In a recent paper published online in Molecular Psychiatry, Skafidas et al.1 report a classifier for identifying individuals at risk for autism spectrum disorders (ASDs). Their classifier is based on 267 single-nucleotide polymorphisms (SNPs) that were selected from the results of a pathway analysis using cases from the Autism Genetic Resource Exchange (AGRE).1 Using within-sample cross-validation, the authors claim a classification accuracy for ASDs of 85.6%. They subsequently applied their classifier to ASD cases from the Simons Foundation Autism Research Initiative (SFARI) and controls from the Wellcome Trust Birth Cohort (WTBC) and report ASD classification accuracy of 71.7%.

We believe that the claims made by Skafidas et al.1 are inconsistent with current knowledge of the genetics of ASDs,2 and inconsistent with the expected precision of risk predictions for complex psychiatric disorders. Further, as classification accuracy depends on the size of the discovery sample, the results are also inconsistent with the size of the sample they employed (only 123 controls were included in the discovery set).

Despite the fact that seizures are commonly associated with autism spectrum disorder (ASD), the effectiveness of treatments for seizures has not been well studied in individuals with ASD. This manuscript reviews both traditional and novel treatments for seizures associated with ASD. Studies were selected by systematically searching major electronic databases and by a panel of experts that treat ASD individuals. Only a few anti-epileptic drugs (AEDs) have undergone carefully controlled trials in ASD, but these trials examined outcomes other than seizures. Several lines of evidence point to valproate, lamotrigine, and levetiracetam as the most effective and tolerable AEDs for individuals with ASD. Limited evidence supports the use of traditional non-AED treatments, such as the ketogenic and modified Atkins diet, multiple subpial transections, immunomodulation, and neurofeedback treatments.

Although specific treatments may be more appropriate for specific genetic and metabolic syndromes associated with ASD and seizures, there are few studies which have documented the effectiveness of treatments for seizures for specific syndromes. Limited evidence supports l-carnitine, multivitamins, and N-acetyl-l-cysteine in mitochondrial disease and dysfunction, folinic acid in cerebral folate abnormalities and early treatment with vigabatrin in tuberous sclerosis complex.

Abstract

Background Abundant, indirect epidemiological evidence indicates that influenza contributes to all-cause mortality and cardiovascular hospitalisations with studies showing increases in acute myocardial infarction (AMI) and death during the influenza season.

Objective To investigate whether influenza is a significant and unrecognised underlying precipitant of AMI.

Design Case-control study.

Setting Tertiary referral hospital in Sydney, Australia, during 2008 to 2010.

Patients Cases were inpatients with AMI and controls were outpatients without AMI at a hospital in Sydney, Australia.

Main outcome measures Primary outcome was laboratory evidence of influenza. Secondary outcome was baseline self-reported acute respiratory tract infection.

Results Of 559 participants, 34/275 (12.4%) cases and 19/284 (6.7%) controls had influenza (OR 1.97, 95% CI 1.09 to 3.54); half were vaccinated. None were recognised as having influenza during their clinical encounter. After adjustment, influenza infection was no longer a significant predictor of recent AMI. However, influenza vaccination was significantly protective (OR 0.55, 95% CI 0.35 to 0.85), with a vaccine effectiveness of 45% (95% CI 15% to 65%).

Conclusions Recent influenza infection was an unrecognised comorbidity in almost 10% of hospital patients. Influenza did not predict AMI, but vaccination was significantly protective but underused. The potential population health impact of influenza vaccination, particularly in the age group 50–64 years, who are at risk for AMI but not targeted for vaccination, should be further explored. Our data should inform vaccination policy and cardiologists should be aware of missed opportunities to vaccinate individuals with ischaemic heart disease against influenza.

Abstract

PROBLEM:

Post-vaccination autoimmune phenomena are a major facet of the autoimmune/inflammatory syndrome induced by adjuvants (ASIA) and different vaccines, including HPV, have been identified as possible causes.

METHOD OF STUDY:

The medical history of three young women who presented with secondary amenorrhea following HPV vaccination was collected. Data regarding type of vaccine, number of vaccination, personal, clinical and serological features, as well as response to treatments were analyzed.

RESULTS:

All three patients developed secondary amenorrhea following HPV vaccinations, which did not resolve upon treatment with hormone replacement therapies. In all three cases sexual development was normal and genetic screen revealed no pertinent abnormalities (i.e., Turner's syndrome, Fragile X test were all negative). Serological evaluations showed low levels of estradiol and increased FSH and LH and in two cases, specific auto-antibodies were detected (antiovarian and anti thyroid), suggesting that the HPV vaccine triggered an autoimmune response. Pelvic ultrasound did not reveal any abnormalities in any of the three cases. All three patients experienced a range of common non-specific post-vaccine symptoms including nausea, headache, sleep disturbances, arthralgia and a range of cognitive and psychiatric disturbances. According to these clinical features, a diagnosis of primary ovarian failure (POF) was determined which also fulfilled the required criteria for the ASIA syndrome.

CONCLUSION:

We documented here the evidence of the potential of the HPV vaccine to trigger a life-disabling autoimmune condition. The increasing number of similar reports of post HPV vaccine-linked autoimmunity and the uncertainty of long-term clinical benefits of HPV vaccination are a matter of public health that warrants further rigorous inquiry.

Trends in Hospitalizations of Children With Inflammatory Bowel Disease Within the United States From 2000 to 2009

Science post imageBackground: The incidence and prevalence of pediatric inflammatory bowel disease (IBD) seems to be increasing in North America and Europe. Our objective was to evaluate hospitalization rates in children
with IBD in the United States during the decade 2000 to 2009.

Methods: We analyzed cases with a discharge diagnosis of Crohn disease (CD) and ulcerative colitis (UC) within the Healthcare Cost and Utilization Project Kids’ Inpatient Database, Agency for Healthcare Research and Quality.

Results: We identified 61,779 pediatric discharges with a diagnosis of IBD (CD, 39,451 cases; UC, 22,328 cases). The number of hospitalized children with IBD increased from 11,928 to 19,568 (incidence, 43.5Y71.5 cases per 10,000 discharges per year; P G 0.001). For CD, the number increased from 7757 to 12,441 (incidence, 28.3Y45.0; P G 0.001)and for UC, 4171 to 7127 (15.2Y26.0; P G 0.001).

Overall, there was a significant increasing trend for pediatric hospitalizations with IBD, CD,
and UC (P G 0.001). In addition, there was an increase in IBD-related complications and comorbid disease burden (P G 0.01).

Conclusion: There was a significant increase in the number and incidence of hospitalized children with IBD in the United States from 2000 to 2009.  Read the full text at American Federation for Medical Research.

ABSTRACT:


We report the history of a child with autism and epilepsy who, after limited response to other interventions following her regression into autism, was placed on a gluten-free, casein-free diet, after which she showed marked improvement in autistic and medical symptoms. Subsequently, following pubertal onset of seizures and after failing to achieve full seizure control pharmacologically she was advanced to a ketogenic diet that was customized to continue the gluten-free, casein-free regimen. On this diet, while still continuing on anticonvulsants, she showed significant improvement in seizure activity. This gluten-free casein-free ketogenic diet used medium-chain triglycerides rather than butter and cream as its primary source of fat. Medium-chain triglycerides are known to be highly ketogenic, and this allowed the use of a lower ratio (1.5:1) leaving more calories available for consumption of vegetables with their associated health benefits. Secondary benefits included resolution of morbid obesity and improvement of cognitive and behavioral features. Over the course of several years following her initial diagnosis, the child’s Childhood Autism Rating Scale score decreased from 49 to 17, representing a change from severe autism to nonautistic, and her intelligence quotient increased 70 points. The initial electroencephalogram after seizure onset showed lengthy 3 Hz spike-wave activity; 14 months after the initiation of the diet the child was essentially seizure free and the electroencephalogram showed only occasional 1-1.5 second spike-wave activity without clinical accompaniments.

ABSTRACT

The question of whether the prevalence increase observed in autism due to an actual increase in the incidence of autism is a matter of concern to professional psychologists, and has been a matter of debate. As professionals trained in diagnosis and research methodology, the opinions of psychologists are of interest. We report the results of what we believe to be the first survey of professional opinion on the topic. Results suggest that among professional psychologists with a terminal degree (n = 88), the majority believe that diagnostic changes can not fully account for the observed increase; 72% reported either the true rate may have, or definitely has, increased. In this sample, the professionals who are certain about the occurrence of a real increase (n=20) are five times as many as those who do not think the increase has occurred (n=4). These results are not meant to document whether or not an increase has or has not occurred, but instead speak to the question of consensus opinion among professional psychologists. What experts believe is an empirical question, and statements about what experts believe should be empirically based.

Autism Linked to Increased Genetic Change in Regions of Genome Instability

Science post imageRead the full report at Science Codex.

Children with autism have increased levels of genetic change in regions of the genome prone to DNA rearrangements, so called "hotspots," according to a research discovery to be published in the print edition of the journal Human Molecular Genetics. The research indicates that these genetic changes come in the form of an excess of duplicated DNA segments in hotspot regions and may affect the chances that a child will develop autism -- a behavioral disorder that affects about 1 of every 88 children in the United States, according to the Centers for Disease Control.

Earlier work had identified, in children with autism, a greater frequency of rare DNA deletions or duplications, known as DNA copy number changes. These rare and harmful events are found in approximately 5 to 10 percent of cases, raising the question as to what other genetic changes might contribute to the disorders known as autism spectrum disorders.

The new research shows that children with autism have -- in addition to these rare events -- an excess of duplicated DNA including more common variants not exclusively found in children with autism, but are found at elevated levels compared to typically developing children. The research collaboration includes groups led at Penn State by Scott Selleck; at the University of California Davis/MIND Institute by Isaac Pessah, Irva Hertz-Picciotto, Flora Tassone, and Robin Hansen; and at the University of Washington by Evan Eichler.

Research: From the Superb to the Questionable

Polio vaxBelow is an article that ran in Vaccination News.  Thank you to VN for allowing us to excerpt it here.

By  F Edward Yazbak MD

It is safe to say that in the last few years, researchers who dared question a vaccination policy or only mention vaccination and autism in the same sentence were certain to get a public and unrelenting flagellation.

I was therefore overjoyed when the accomplishment of a distinguished researcher in that venue was recognized. It was certainly wonderful to hear that the Briloff Committee at Baruch College very recently awarded The Briloff Prize for 2012 to Dr. Gayle DeLong for her magnificent exposé titled “Conflicts of Interest in Vaccine Safety Research”. In the citation, the Committee described Dr. DeLong’s publication as “an excellent exposition of ethical issues and biases in the examination of conflicts of interests related to vaccine safety research. The main thrust of this paper is the questioning of the ethics of industry sponsorship of vaccine use.”

 The abstract of Dr. DeLong’s article  on PubMed summarizes the extensive document quite clearly:

“Conflicts of interest (COIs) cloud vaccine safety research. Sponsors of research have competing interests that may impede the objective study of vaccine side effects. Vaccine manufacturers, health officials, and medical journals may have financial and bureaucratic reasons for not wanting to acknowledge the risks of vaccines. Conversely, some advocacy groups may have legislative and financial reasons to sponsor research that finds risks in vaccines. Using the vaccine-autism debate as an illustration, this article details the conflicts of interest each of these groups faces, outlines the current state of vaccine safety research, and suggests remedies to address COIs. Minimizing COIs in vaccine safety research could reduce research bias and restore greater trust in the vaccine program.”
Dr. DeLong’s previous publication (2011) titled “A positive association found between autism prevalence and childhood vaccination uptake across the U.S. population”  was, I thought, just as remarkable.  Its PubMed abstract was also an informative and clear summary of the author’s extensive research:

Science Summary: Higher levels of several toxic metals found in children with autism

Science post imageIn a recently published study in the journal Biological Trace Element Research, Arizona State University researchers report that children with autism had higher levels of several toxic metals in their blood and urine compared to typical children. The study involved 55 children with autism ages five to 16 years old compared to 44 controls of similar age and gender.

The autism group had significantly higher levels of lead in their red blood cells (+41 percent) and significantly higher urinary levels of lead (+74 percent), thallium (+77 percent), tin (+115 percent), and tungsten (+44 percent). Lead, thallium, tin, and tungsten are toxic metals that can impair brain development and function, and also interfere with the normal functioning of other body organs and systems.   Read the full study Toxicological Status of Children with Autism vs. Neurotypical Children and the Association with Autism Severity.

Toxic Metal Burdens May Epigenetically Play Principal Roles as Environmental Factors in Autistic Disorders

  Science post image Estimation of autistic children by metallomics analysis

Scientific Reports 3, Article number: 1199 doi:10.1038/srep01199
Clarification of the pathogenesis and treatment of autism spectrum disorders is one of the challenges today. In this study, we examine scalp hair concentrations of 26 trace elements for 1,967 children with autistic disorders (1,553 males and 414 females). Five-hundred and eighty-four (29.7%), 347 (17.6%) and 114 (5.8%) subjects was found deficient in zinc, magnesium and calcium, respectively, and 2.0% or less in the other essential metals. The incidence rate of mineral deficiency was highly observed in infants aged 0-3 year-old. In contrast, 339 (17.2%), 168 (8.5%) and 94 (4.8%) individuals was found suffering from high burden of aluminium, cadmium and lead, and 2.8% or less from mercury and arsenic burden.

These findings suggest that infantile zinc- and magnesium-deficiency and/or toxic metal burdens may epigenetically play principal roles as environmental factors in autistic disorders and that metallomics approach may lead to early screening and prevention of the neurodevelopment disorders.

Michael Pichichero's Reasoning on Mercury for Global Treaty

PichicheroBy Jim Thompson

Dr. Michael Pichichero is an industry scientist and he endorses a mercury-based compound called Thimerosal as a “safe” and “effective” preservative in vaccines worldwide. 

In a recently published report “Perspective – Report to WHO: No New Concerns About Thimerosal” he acknowledges that his “institution has received research grants from GlaxoSmithKline, Sanofi Pasteur, Pfizer, Novartis, and Crucell for new vaccine and product development.”  Also he states in his report that “The evidence suggests the 2008 endorsement of the use of thimerosal as a safe and effective preservative in vaccines for children worldwide should remain.” 

In addition he alludes to his remote presentation to the United Nations Negotiating Committee Meeting on April 3-4, 2012 which was made for “their consideration and vote” regarding the continuation of mercury in vaccines used worldwide.   And it was in that same time frame that the World Health Organization's (WHO's) Strategic Advisory Committee (SAGE) in Geneva recommended that “Thimerosal, a preservative used to prevent contamination in multidose vaccine vials, be exempted from a pending international treaty aimed at reducing global health hazards by limiting exposure to mercury.”  (See WHO Weekly Epidemiological Record).

Now it is possible that this industry scientist’s reasoning is based on an unfounded presumption that mercury leaves the brain faster than mercury from fish.  He states “[a] total of five studies of blood and hair mercury in children have now been published, and all show that the foundational presumption of similar pharmacokinetics between methylmercury and ethylmercury was incorrect.”  But do these studies really indicate what happens in a child’s brain? 

To answer that one cannot rely solely on human studies reporting reduced mercury content in blood and hair.  It is also important to recognize the fact that an animal study clearly shows that Thimerosal vaccine preservative injections result in inorganic mercury levels in brain tissue in infant monkeys at higher levels and longer time frames than from exposure to mercury in fish.

Autism Science Digest: Aluminum Toxicity in Mitochondrial Dysfunction and ASD

ASD coverThank you to our friends at Autism Science Digest magazine for allowing us to excerpt this article. 

Aluminum Toxicity in Mitochondrial Dysfunction and ASD

By Nancy Mullan, MD, and Amy Yasko, PhD, AMD, FAAIM

Currently, there is intense interest and discussion surrounding the high incidence of mitochondrial disease and/or dysfunction in children with autism spectrum disorders (ASDs). This interest is fueled at least in part by the 2008 Hannah Poling decision.1,2 In this landmark case, the federal government’s Vaccine Injury Compensation Program (VICP) agreed to award damages to the Poling family when their daughter Hannah, who had an underlying mitochondrial disorder, developed autism-like symptoms after receiving a series of vaccines in a single day. Because Hannah Poling’s father is a medical doctor who was in the department of neurology at Johns Hopkins Hospital at the time that his daughter’s vaccine injury occurred, her case carried great weight. The Poling case, therefore, served to draw a great deal more attention to mitochondrial disorders within autism than these disorders had previously received.

A carefully executed review and meta-analysis of mitochondrial dysfunction in ASD by Rossignol and Frye discerned that the prevalence of full syndrome mitochondrial disease in children with ASD is significantly higher than it is in children in general.3 Their analysis also revealed that many children with ASD have findings on laboratory tests that indicate some degree of mitochondrial dysfunction, although not full syndrome mitochondrial disease. Together, these findings indicate a high degree of abnormal mitochondrial function in children with ASD, which other research has corroborated.2,4-9

Best of AofA: Brian Deer's Second Award - As Meaningless As The First

Dumb deerAuthor's Note: This post originally ran in 2011, after the vaccine lobby's hired gun Brian Deer received his second "Press Award," to explain why his second such award is as meaningless as his first. Later that same year, Deer won another "award" from the UK pharma front group "HealthWatch." Then just a few days ago, another front group in the UK run by pharma-backed "science" writer Simon Singh gave Dr. Andrew Wakefield - whose Lancet paper was vindicted by colleague Prof. John Walker-Smith's successful appeal earlier this year - a mock award for "quackery." In response, we are re-running this piece to remind readers that Brian Deer's "awards" are just as farcical. 

By Jake Crosby

The UK’s “Press Awards” are not nicknamed the “Hackademy Awards” for nothing, especially in the case of Brian Deer. He has been given not one, but two such awards. The claim, made by Brian Deer, that the UK Press Awards are like the Pulitzer Prize is laughable and absurd.

The UK’s Society of Editors runs the Press Awards. Sitting on the Editors’ advisory council is Les Hinton, who recently resigned as CEO of Dow Jones in the wake of the Murdoch phone hacking scandal. Also on that committee is Rebekah Brooks, who resigned as senior executive of News International - which publishes The Sunday Times - and was then arrested.

For over a decade,  Brian Deer's only award was based on a faulty premise. It was called “Specialist Reporter of the year.” The judges said Deer was “the only journalist in Britain that polices the drug companies.” However, during the year for which he won his award, 1998, Brian Deer wrote an article alleging that patients who suffered neurological injury from the DTP vaccine were not really injured and should therefore not have received legal compensation for their injuries. That is the exact opposite of “policing” the drug companies, but is instead harrassing the victims of defective drug company products. In 2004, Glenn Frankel reported in the Washington Post that one of Brian Deer’s specialties “was tracking down false claims of damage from vaccines.

Weeks after the bogus premise behind his first award was reported on Age of Autism, Brian Deer was nominated for “News Reporter of the Year” and also for “Specialist Reporter of the year,” the latter of which he won at the ceremony in London’s Savoy Hotel on April 5th, 2011. That award was given to Deer for his smear campaign against Dr. Andrew Wakefield.

The measure of any great or even good journalist must be his independence. Journalism awards are supposed to be based on independent assessments of reporters’ work, otherwise they are meaningless. Furthermore, it seems too perfect that Brian Deer was nominated for a Press Award (that he would later win) mere weeks after Age of Autism revealed he had only won one award.

How surprising can this really be given that the Academy of Judges for this year’s awards ceremony included Richard Caseby, managing editor of The Sunday Times? Caseby became notorious for his exchange with Rosemary Kessick – one of the few parents of the Lancet 12 children that Brian Deer actually interviewed.

Following a 6-hour interrogation of Kessick by Deer in 2003, during which he falsely gave his name as “Brian Lawrence,” she complained to The Sunday Times executive editor John Witherow. The exchange is detailed by Dan Olmsted in his article,  An Elaborate Fraud, Part 2: In Which a Murdoch Newspaper’s Deceptive Tactics Infect the British Medical Journal.

Unfortunately, Kessick might as well have been complaining to GlaxoSmithKline, the board of which has retained News International boss, James Murdoch, since 2009. John Witherow recently wrote in a self-congratulatory piece about The Sunday Times’ investigative journalism on July 17th:

There have, of course, been many other investigations, including Brian Deer's outstanding work on exposing the doctor behind the false MMR scare.

This sentence exposes a clear desire to try and shift the arguments off the ground of the Sunday Times and GSK and into a more general arena so showing that what happened to Wakefield was a result of universal investigating and popular will. In fact one of the most staggering things about the Wakefield case was that Deer carried sole responsibility for it prior to lodging it with the GMC; no other investigative journalist in the world uncovered or wrote anything original critical of Wakefield besides Deer. 

Instead of Witherow responding to Kessick’s complaint, Richard Caseby wrote back:

Abstract

Hans Asperger originally used the term "autistic psychopathy" to describe his patients on the autism spectrum, leading to a possible confusion with psychopathic disorder and delinquent behaviour. We conducted a penal register search for 177 former patients of Asperger's clinic with a childhood diagnosis of "autistic psychopathy" or features of the disorder in Austria. The mean percentage of registered convictions was similar to that in the general male population of Austria over the studied time period. A qualitative assessment of offence types in Asperger's former patients suggests that the nature of offences does not differ from that in the general population. In this original cohort of Asperger's patients, convictions were no more common than in the general male population.

Abstract

Background: The proper understanding of a true risk from vaccines is crucial for avoiding unnecessary adverse reactions (ADRs). However, to this date no solid tests or criteria have been established to determine whether adverse events are causally linked to vaccinations.

Objectives: This research was carried out to determine whether or not some serious autoimmune and neurological ADRs following HPV vaccination are causal or merely coincidental and to validate a biomarker-based immunohistochemical (IHC) protocol for assessing causality in case of vaccination-suspected serious adverse neurological outcomes.

Methods: Post-mortem brain tissue specimens from two young women who suffered from cerebral vasculitis- type symptoms following vaccination with the HPV vaccine Gardasil were analysed by IHC for various immuno- inflammatory markers. Brain sections were also stained for antibodies recognizing HPV-16L1 and HPV-18L1 antigen which are present in Gardasil.

Results: In both cases, the autopsy revealed no anatomical, microbiological nor toxicological findings that might have explained the death of the individuals. In contrast, our IHC analysis showed evidence of an autoimmune vasculitis potentially triggered by the cross-reactive HPV-16L1 antibodies binding to the wall of cerebral blood vessels in all examined brain samples. We also detected the presence of HPV-16L1 particles within the cerebral vasculature with some HPV-16L1 particles adhering to the blood vessel walls. HPV-18L1 antibodies did not bind to cerebral blood vessels nor any other neural tissues. IHC also showed increased T-cell signalling and marked activation of the classical antibody-dependent complement pathway in cerebral vascular tissues from both cases. This pattern of complement activation in the absence of an active brain infection indicates an abnormal triggering of the immune response in which the immune attack is directed towards self-tissue.

Conclusions: Our study suggests that HPV vaccines containing HPV-16L1 antigens pose an inherent risk for triggering potentially fatal autoimmune vasculopathies.

Practice implications: Cerebral vasculitis is a serious disease which typically results in fatal outcomes when undiagnosed and left untreated. The fact that many of the symptoms reported to vaccine safety surveillance databases following HPV vaccination are indicative of cerebral vasculitis, but are unrecognized as such (i.e., intense persistent migraines, syncope, seizures, tremors and tingling, myalgia, locomotor abnormalities, psychotic symptoms and cognitive deficits), is a serious concern in light of the present findings. It thus appears that in some cases vaccination may be the triggering factor of fatal autoimmune/neurological events. Physicians should be aware of this association.

Abstract

We tested whether maternal vitamin D insufficiency during pregnancy is related to the autism phenotype. Serum 25(OH)-vitamin D concentrations of 929 women were measured at 18 weeks' pregnancy. The mothers of the three children with a clinical diagnosis of autism spectrum disorder had 25(OH)-vitamin D concentrations above the population mean. The offspring of 406 women completed the Autism-Spectrum Quotient in early adulthood. Maternal 25(OH)-vitamin D concentrations were unrelated to offspring scores on the majority of scales. However, offspring of mothers with low 25(OH)-vitamin D concentrations (<49 nmol/L) were at increased risk for 'high' scores (≥2SD above mean) on the Attention Switching subscale (odds ratio: 5.46, 95 % confidence interval: 1.29, 23.05). The involvement of maternal vitamin D during pregnancy in autism requires continued investigation.

AofA Science Summary: Are systemizing and autistic traits related to talent and interest in mathematics and engineering?

Science post imageProfessor Simon Baron Cohen's research includes the theory of the extreme male brain: "Research on relatives of people with Asperger syndrome and autism has found that their fathers and grandfathers are twice as likely to be engineers as the general population. Natural science students have more relatives with autism than humanities students. Asperger syndrome is found more often in mathematicians and their siblings than in the general population. Both mothers and fathers of children with Asperger syndrome tend to score high on systemizing. Both mothers and fathers of children with autism or Asperger syndrome often have father who worked in systemizing occupations. Both mothers and fathers of children with autism have a strongly masculine pattern of brain activity when doing systemizing activity.*"  The study below found otherwise.

Testing some of the central claims of the empathizing-systemizing theory. Morsanyi K, Primi C, Handley SJ, Chiesi F, Galli S. Source School of Psychology, University of Plymouth, UK Department of Psychology, University of Florence, Italy. Abstract In two experiments, we tested some of the central claims of the empathizing-systemizing (E-S) theory.

Experiment 1 showed that the systemizing quotient (SQ) was unrelated to performance on a mathematics test, although it was correlated with statistics-related attitudes, self-efficacy, and anxiety. In Experiment 2, systemizing skills, and gender differences in these skills, were more strongly related to spatial thinking styles than to SQ. In fact, when we partialled the effect of spatial thinking styles, SQ was no longer related to systemizing skills.

Additionally, there was no relationship between the Autism Spectrum Quotient (AQ) and the SQ, or skills and interest in mathematics and mechanical reasoning. We discuss the implications of our findings for the E-S theory, and for understanding the autistic cognitive profile. ©2011 The British Psychological Society. PMID: 23034108 [PubMed - in process]

Reversible blindness in bilateral optic neruritis associated with nasal flu vaccine.

Crawford CGrazko MBRaymond WR 4thRivers BAMunson PD.

Abstract BACKGROUND:

Various case reports have shown possible associations between optic neuritis and different vaccines. Some of the vaccines include influenza, hepatitis B and anthrax

PURPOSE:

To present evidence for a causal relationship between optic neuritis and Live Attenuated Influenza Vaccine (LAIV), administered as nasal flu vaccine.

METHODS:

Case Report. In a 13-year-old male with bilateral optic neuritis, detailed clinical history, neuro-ophthalmologic examination, magnetic resonance imaging, stereo-disc photos, visual field testing, ocular coherence tomography, blood tests and cerebral spinal fluid analysis were performed.

RESULTS:

Exam findings on presentation: BCVA: 20/CF OD; 20/LP OS. Positive relative afferent pupil defect OD. Unremarkable anterior segment and posterior segment exam. No papillitis or papilledema. Global visual field defect OU based on Humphrey 30-2. MRI: diffuse enlargement of Optic Chiasm with inflammation of distal optic nerves bilateral. Blood cultures and CSF were negative. Patient received 3 divided doses of methyl prednisone with mild improvement of vision upon hospital discharge and marked improvement of vision at 2 month follow up.

CONCLUSION:

In this child, no infectious, vascular, granulomatous, viral or immune-related cause of optic neuritis was identified. This case provides compelling evidence that supports the nasal flu vaccination as a cause of optic neuritis.

Abstract

Children with autism spectrum disorders (ASD) experience high rates of anxiety, sensory processing problems, and gastrointestinal (GI) problems; however, the associations among these symptoms in children with ASD have not been previously examined. The current study examined bivariate and multivariate relations among anxiety, sensory over-responsivity, and chronic GI problems in a sample of 2,973 children with ASD enrolled in the Autism Treatment Network (ages 2-17 years, 81.6 % male). Twenty-four percent of the sample experienced at least one type of chronic GI problem (constipation, abdominal pain, bloating, diarrhea, and/or nausea lasting three or more months). Children with each type of GI problem had significantly higher rates of both anxiety and sensory over-responsivity. Sensory over-responsivity and anxiety were highly associated, and each provided unique contributions to the prediction of chronic GI problems in logistic regression analyses. The results indicate that anxiety, sensory over-responsivity and GI problems are possibly interrelated phenomenon for children with ASD, and may have common underlying mechanisms.

• Neurological Abnormalities in ASD

Children with autism have been found to have many neurological abnormalities. These include differences in brain function, structure and connectivity, neurotransmitter and metabolic abnormalities and electrical disturbances in the brain including seizures. This talk will review some of the important aspects of these neurological abnormalities and their treatments.

Saturday, August 4, 2012, 10:00 AM - 12:00 PM

One Talk Covering Two Common Issues

• Mitochondrial Disorders in Autism Mitochondria

There is strong evidence that many children with autism also have a mitochondrial disorder, which means that the mitochondria produce less fuel for the body and for the brain. This talk will discuss the challenges of how to test for mitochondrial disorders, as well as the current treatments available for them.

• Seizures in Autism

A New National Survey on Treatments: Approximately 25% of children and adults with autism have seizures, and another 50% have sub-clinical seizures that are often undetected but may affect their intellectual functioning. This presentation will briefly review seizure issues in autism, and then present the new results of a national survey of over 500 children and adults with seizures, with a comparison of the benefits and possible side effects of many medical, dietary, and nutritional treatments.

Dr. Richard Frye, M.D., Ph.D., who is the Director of Autism Research and Associate Professor of Pediatrics at The University of Arkansas for Medical Sciences, speaks across the country on pediatric neurological disorders.

Gene Expression Profiles of Inflamed Bowel Biopsy Tissue in ASD Children Are Consistent with Inflammatory Bowel Disease

Background: Chronic gastrointestinal (GI) symptoms in children with autism spectrum disorders (ASD) are common and not well understood. It is unclear if GI symptoms and intestinal mucosal inflammatory changes seen in children with ASD represent a variant of inflammatory bowel disease (IBD) versus non-specific colitis or “normal” mucosal cellular composition. Some studies have demonstrated histochemical and immunohistochemical features of the bowel mucosa, lamina propria and mucosal basement membrane which may be unique to children with ASD. The recent emergence of gene expression profiling as a valid methodology for distinguishing various forms of IBD potentially adds a further tool in defining the characteristics of ASD-associated intestinal inflammation.

Objectives: The goal of this study was to use a molecular approach to evaluate gene expression profiles in both histologically inflamed and non-inflamed ileocolonic biopsy specimens from ASD children with chronic GI symptoms and to compare them to gene expression profiles in ileocolonic tissue of neurotypical children with Crohn’s disease. Significant overlap of gene expression in these two groups would suggest that ASD-GI represents an IBD variant; differences in the ASD-GI gene expression profile would highlight the nature of its distinction from Crohn’s disease.

Methods: Study tissue consisted of ileocolonic biopsies from two groups: (1) children with an ASD undergoing ileocolonoscopy for active gastrointestinal symptoms and, (2) neurotypical children diagnosed with Crohn’s disease.  All tissue specimens were collected under appropriate IRB approval. For each individual (seven per group; fourteen in total) two biopsies were used: one from the terminal ileum with active inflammatory changes and one from the colon demonstrating normal mucosa (control).  Total RNA was isolated from the individual tissue biopsy specimens and used to query whole genome DNA microarrays. For each of the two groups, ASD-GI and CD, differential gene expression was determined by comparing the inflamed tissue within a group to the control tissues from the same group. Next, differential gene expression was compared between the ASD-GI and CD groups to evaluate similarities and differences.  

Results: In each group there were ~2000 transcripts differentially expressed between inflamed and control tissue. Within the 900 differentially expressed genes shared by both ASD-GI and CD, two highly relevant biological functional groups represented by these transcripts were gastrointestinal disease (including CD [p = 0.001] and IBD [p = 0.001]) and inflammatory response [p = 0.000003]. In the 912 differentially expressed transcripts unique to ASD-GI, the most significant biological functional group represented was gastrointestinal disease (including IBD and CD). In contrast, there were 1200 genes uniquely differentially expressed in CD and the primary biological functions represented by these transcripts were immune response [p = 6.6 x 10-14] and autoimmune disease [p = 4 x 10-7].    

Conclusions: These results demonstrate that ASD-GI presents a gene expression profile significantly overlapping with Crohn’s disease and consistent with the larger category of inflammatory bowel disease.

Abstract

Idiopathic autism, caused by genetic susceptibility interacting with unknown environmental triggers, has increased dramatically in the past 25 years. Identifying environmental triggers has been difficult due to poorly understood pathophysiology and subjective definitions of autism. The use of antidepressants by pregnant women has been associated with autism. These and other unmetabolized psychoactive pharmaceuticals (UPPs) have also been found in drinking water from surface sources, providing another possible exposure route and raising questions about human health consequences. Here, we examined gene expression patterns of fathead minnows treated with a mixture of three psychoactive pharmaceuticals (fluoxetine, venlafaxine & carbamazepine) in dosages intended to be similar to the highest observed conservative estimates of environmental concentrations. We conducted microarray experiments examining brain tissue of fish exposed to individual pharmaceuticals and a mixture of all three. We used gene-class analysis to test for enrichment of gene sets involved with ten human neurological disorders. Only sets associated with idiopathic autism were unambiguously enriched. We found that UPPs induce autism-like gene expression patterns in fish. Our findings suggest a new potential trigger for idiopathic autism in genetically susceptible individuals involving an overlooked source of environmental contamination.

Are Names of Children with Attention Deficit Hyperactivity Disorder More 'Hyperactive'?

Source

Child and Adolescent Division, Psychiatry Department, Geha Mental Health Center, Petah Tiqva, Israel.

Abstract

Background: The role of the meaning of given names has been noted in psychotherapy as well as in everyday life. This study aimed to investigate the possible association between the nature of given names of children and attention deficit hyperactivity disorder (ADHD) diagnosis. Sampling and Methods: A total of 134 given names of children and adolescent patients diagnosed as having ADHD were compared with those of an age- and gender-matched randomly chosen control group from the general population. The first names of the two cohorts were compared with regard to the following: the literal meaning of their names, whether the name constitutes a verb, the prevalence of each name and their length (number of syllables). Results: The meaning of first names of children and adolescents with ADHD combined type were rated by referees as expressing significantly more activity and containing less syllables than the names of controls. In addition, the prevalence of their names was significantly lower than that of names used in the general population. All findings remained significant following Bonferroni adjustment. Conclusions: Our findings demonstrate an intriguing relationship between children's given names and ADHD diagnosis. Given names may serve as a possible predictor of later diagnosis of ADHD. Clinicians should be more attentive to given names in the context of child psychiatric evaluation and therapy.

Abstract

Thimerosal, an organomercury compound, has been widely used as a preservative. Therefore, concerns have been raised about its neurotoxicity. We recently demonstrated perturbation of early serotonergic development by prenatal exposure to thimerosal (Ida-Eto et al. (2011) [11]). Here, we investigated whether prenatal thimerosal exposure causes persistent impairment after birth. Analysis on postnatal day 50 showed significant increase in hippocampal serotonin following thimerosal administration on embryonic day 9.

Furthermore, not only serotonin, striatal dopamine was significantly increased. These results indicate that embryonic exposure to thimerosal produces lasting impairment of brain monoaminergic system, and thus every effort should be made to avoid the use of thimerosal.

Abstract

Abstract Objective: Weight gain and metabolic adverse effects of second-generation antipsychotics (SGAs) have become a major concern, particularly in youth. However, the specific contribution of SGAs versus other medications or the underlying illness is unclear. Methods: In a chart review study of psychiatric outpatients aged ≤18 years treated with SGAs and psychiatric controls without lifetime SGA, use body mass index (BMI) z-scores between patients and controls were compared in the entire sample, patients without co-medications, diagnostic subgroups, and age subgroups. In patients with follow-up data, weight z-score change was calculated. Results: Altogether, 592 Caucasian patients aged 4-18 (mean: 10.0) years with a psychiatric diagnosis were included. BMI z-scores in 96 youth treated with SGAs for 9.0±6.1 months were significantly higher than in 496 patients without lifetime SGA use (0.81±1.1 vs. 0.05±1.2; p<0.0001). BMI z-score differences remained significant in all age groups <16 years old. In sub-analyses, results remained the same after eliminating patients on any co-medication (0.82±1.2 vs. 0.23±1.2; p<0.0001) and in patients with (0.75±1.2 vs. 0.17±1.1, p<0.0001) or without autism spectrum disorders (1.1±1.0 vs. -0.02±1.2, p<0.0001). Significantly more SGA-treated youth were obese (27.1% vs. 9.5%, odds ratio [OR]: 3.55, 95% confidence interval [CI]:2.07-6.08) or overweight (21.9% vs. 8.3%, OR: 3.11, 95%CI: 1.75-5.52). In 24 patients (92.3% antipsychotic-naïve) with 6.6 months follow-up, weight z-score increased significantly from -0.17±1.5 to 0.25±1.4 (p<0.0001) with 12.5% transitioning to overweight or obese status.

Conclusion: These data show robust and significant differences in sex- and age-adjusted body weight and weight status in young pediatric Caucasian samples with and without use of SGAs independent of Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision (DSM-IV-TR) (American Psychiatric Association 2000 ) diagnosis and nonantipsychotic medications. Weight status and metabolic effects of SGAs require careful attention, especially in youth.

Dr. Ian Lipkin of Columbia - A Scientist on the Road to Damascus?

Ian LipkinBy Kent Heckenlively, Esq.

There is a most curious interview with Dr. Ian Lipkin in the April 2012 issue of Discover magazine entitled "In the Lab with the World's Greatest Virus Hunter".  I can't help but notice that Dr. Lipkin, director of the Center for Infection and Immunity at Columbia University's Mailman School of Public Health and the scientist who first identified West Nile Virus sounds more like a bio-med autism parent than a CDC spokesman who claims that while we don't know what causes autism, "we're sure it's not vaccines."

Many will no doubt remember it was Lipkin's study which  supposedly  disproved the work of Dr. Andrew Wakefield regarding the persistence of the vaccine strain of the measles in the gut of children with autism.  And it's certainly true that Lipkin has done little to counter that impression. 

However, a closer look at Lipkin's study reveals a more complicated picture.  Lipkin used the same lab as Wakefield and did identify the measles virus from one of the children with autism he studied. The patient selection criteria was significantly different than that used by Wakefield, and as I have written previously, Lipkin has recently used Wakefield's research in the footnotes to his recent article showing that different bacterial colonies are present in the guts of children with autism.  If Wakefield's research was so dishonest, why would Lipkin ever cite him?

Perhaps all this has set the stage for a conversion on the question of autism, similar to that of the apostle Paul, a former Christian hunter who after having a vision of Christ on the Road to Damascus, became one of the founders of the early Church.  For as much as Dr. Lipkin took the wrong road in regards to Dr. Wakefield's work, there has also been evidence of an exceptionally humane side to the man. 

When Dr. Mady Horning released her study showing that the neurotoxic effects of thimerosal in mice were dependent upon a certain genetic profile, the autism community worried that the long knives were out for her.  This could explain why only certain infants were harmed by the thimerosal in vaccines and not others.  Dr. Horning was sheltered by Dr. Ian Lipkin who made her his research partner, probably saving her academic career in the process.

Recently I've come across Lipkin in the controversy over the XMRV retrovirus and its possible link to both ME/chronic fatigue syndrome and autism.  When the situation with Dr. Judy Mikovits and the Whittemore-Peterson Institute fell apart, Dr. Lipkin had the power to determine whether the research would continue.  I am told by sources that Dr. Lipkin was actually threatened with legal action by various entities and he told them to take a hike.  Instead of succumbing to this pressure, he put Drs. Mikovits, Frank Ruscetti of the National Cancer Institute and discoverer of the first human retrovirus, as well as Jose Montoya of Stanford University, and others in charge of determining the possible link between XMRV (or a related human retrovirus) and these diseases.

Lipkin's willingness to remain agnostic on the question of XMRV (or other related human retroviruses) opens up some other possibilities into how a retrovirus could cause conditions like ME/chronic fatigue syndrome and autism.  A virus or other pathogen may cause collateral damage that is not simply due to the infection, but how the body responds to the pathogen. 

From the Discover magazine interview of April 2012:

Have we reached the point where we can link specific infections to specific psychiatric disorders?

No, the connection is much more complex.  When I worked with LCMV, it became clear that any sort of pertubation could damage the nervous system.  Nerves find their way to specific locations through signposts that are part of the immune system.  And if you increase immunological molecules of certain types, a nerve may jog this way as opposed to the way it's supposed to go.  It may not make a difference what the infectious agent is-bacterial, viral, or parasitic.

Abstract: Conflicts of interest (COIs) cloud vaccine safety research. Sponsors of research have competing interests that may impede the objective study of vaccine side effects. Vaccine manufacturers, health officials, and medical journals may have financial and bureaucratic reasons for not wanting to acknowledge the risks of vaccines. Conversely, some advocacy groups may have legislative and financial reasons to sponsor research that finds risks in vaccines. Using the vaccine-autism debate as an illustration, this article details the conflicts of interest each of these groups faces, outlines the current state of vaccine safety research, and suggests remedies to address COIs. Minimizing COIs in vaccine safety research could reduce research bias and restore greater trust in the vaccine program.

AofA Science Summary: Autism behaviors may be eased by gluten-free, casein-free diet: Penn State College of Medicine

Science post imageAutism behaviors may be eased by gluten-free, casein-free diet: Penn State College of Medicine

Posted on February 29, 2012 by Stone Hearth News

A gluten-free, casein-free diet may lead to improvements in behavior and physiological symptoms in some children diagnosed with an autism spectrum disorder (ASD), according to researchers at Penn State. The research is the first to use survey data from parents to document the effectiveness of a gluten-free, casein-free diet on children with ASD.

Research has shown that children with ASD commonly have GI [gastrointestinal] symptoms, said Christine Pennesi, medical student at Penn State College of Medicine. Notably, a greater proportion of our study population reported GI and allergy symptoms than what is seen in the general pediatric population. Some experts have suggested that gluten- and casein-derived peptides cause an immune response in children with ASD, and others have proposed that the peptides could trigger GI symptoms and behavioral problems.

The team  which included Laura Cousino Klein, associate professor of biobehavioral health and human development and family studies asked 387 parents or primary caregivers of children with ASD to complete a 90-item online survey about their childrens GI symptoms, food allergy diagnoses, and suspected food sensitivities, as well as their children’s degree of adherence to a gluten-free, casein-free diet. The teams results appeared online this month in the journal Nutritional Neuroscience.

Pennesi and Klein and their team found that a gluten-free, casein-free diet was more effective in improving ASD behaviors, physiological symptoms and social behaviors for those children with GI symptoms and with allergy symptoms compared to those without these symptoms. Specifically, parents noted improved GI symptoms in their children as well as increases in their children’s social behaviors, such as language production, eye contact, engagement, attention span, requesting behavior and social responsiveness, when they strictly followed a gluten-free, casein-free diet.

According to Klein, autism may be more than a neurological disease — it may involve the GI tract and the immune system.

There are strong connections between the immune system and the brain, which are mediated through multiple physiological symptoms,” Klein said. “A majority of the pain receptors in the body are located in the gut, so by adhering to a gluten-free, casein-free diet, you’re reducing inflammation and discomfort that may alter brain processing, making the body more receptive to ASD therapies.

The team found that parents who eliminated all gluten and casein from their children’s diets reported that a greater number of their childrens ASD behaviors, physiological symptoms and social behaviors improved after starting the diet compared to children whose parents did not eliminate all gluten and casein. The team also found that parents who implemented the diet for six months or less reported that the diet was less effective in reducing their childs ASD behaviors.

According to the researchers, some of the parents who filled out the surveys had eliminated only gluten or only casein from their children’s diets, but survey results suggested that parents who completely eliminated both gluten and casein from their childs diet reported the most benefit.

While more rigorous research is needed, our findings suggest that a gluten-free, casein-free diet might be beneficial for some children on the autism spectrum, Pennesi said. It is also possible that there are other proteins, such as soy, that are problematic for these children.

The reason Klein and Pennesi examined gluten and casein is because they are two of the most common diet offenders.

“Gluten and casein seem to be the most immunoreactive, Klein said. A childs skin and blood tests for gluten and casein allergies can be negative, but the child still can have a localized immune response in the gut that can lead to behavioral and psychological symptoms. When you add that in with autism you can get an exacerbation of effects.

Kleins advice to parents of children with ASD?

If parents are going to try a gluten-free, casein-free diet with their children, they really need to stick to it in order to receive the possible benefits, she said.

It might give parents an opportunity to talk with their physicians about starting a gluten-free, casein-free diet with their children with ASD.

Abstract

ABSTRACT Autism is a heterogeneous group of complex developmental disabilities that result from a number of possible etiologies. There are a well-known number of comorbidities associated with autism spectrum disorders (ASD), including, commonly, gastrointestinal (GI) pathology, which can include variable combinations of constipation, diarrhea, abdominal pain, gastroesophageal reflux, and vomiting. An American Academy of Pediatrics consensus panel has recommended that prospective studies be carried out to determine the prevalence of GI disorders in ASD and their pathophysiologic basis. In a recent article, Williams et al. [B. L. Williams, M. Hornig, T. Parekh, and W. I. Lipkin, mBio 3(1):e00261-11, 2012] have provided one such study of autism with GI comorbidities by presenting evidence of Sutterella species in ileal mucosal biopsy specimens from patients diagnosed with ASD but not in control children with GI symptoms, suggesting a specific role for Sutterella in ASD. Sutterella sequences represented ~1 to 7% of the total bacterial sequences, and this is a very large effect size on the ileal mucosal composition of the autism phenotype, rivaling or perhaps exceeding the effect size of the ileal Crohn's disease phenotype. This study opens a new field of investigation to study the etiology or consequences of GI comorbidities in ASD.

Autism Diagnosis Age

Big headBy Anne Dachel

The latest discovery about autism is being covered everywhere in the news.  New research from the University of North Carolina, Chapel Hill, has found signs of brain development problems in babies as young as six months using MRI scans. Lead researcher Jason Wolff feels this is very significant because he believes 'there is a potential to intervene, to disrupt autism before it becomes entrenched.'  He described it as 'a whole brain phenomenon.' 

Of course this is only an early study and more needs to be done.  Naturally it doesn't tell us what causes the brains of autistic children to be different and we're cautioned that no one saying that doctors can diagnosis autism in a six month old. 

As far as the cause of autism is concerned, Wolff said it's due to 'a complex interaction between genes and a child's experiences with the world.'   It sounds like 'a child's experiences with the world' could be just about anything and Wolff didn't elaborate.

Reading the coverage this study is getting makes autism sound more like a curiosity than a devastating disorder plaguing a generation of children and one that mainstream medicine can't explain.  You'd never know that this once-rare disorder now strikes one percent of children and almost two percent of boys alone.  There's no sense of urgency in any of the stories on MRI's and autism. 

Sometimes it seems that no one is really interested in finding out anything significant about autism.  Experts are only obligated to come up with some new findings every few months to make it look like someone somewhere is doing something.  That's what's happening with this latest research.   If scientists can find evidence of autism in babies at six months, it would be proof that the parents who claim that their child suddenly regressed into autism following their 18 or 24 month vaccinations are wrong.  It was all just a big coincidence.  The signs of autism were really there much earlier.

Geraldine Dawson, chief science officer at Autism Speaks, was in USA Today trying to capitalize on the findings. 

She'd like to look for the signs of autism in babies in the womb.  Dawson wonders "if brain scans will spot differences in autistic brains even earlier than 6 months, and if the differences could even begin in the womb."

CBS NEWS published the piece, Study: Brain scans detect early signs of autism .  This story began by telling us, "No one is exactly sure what causes autism."  That settled, we hear, "There's also hope that with a better understanding of what causes autism, there may eventually be a more effective treatment or even prevention." 

If you listen to video, CBS News medical correspondent Dr. Jonathan LaPook is heard saying, "I've spoken to a lot of parents of kids who have autism and they are up against it, emotionally, financially.  There's often a sense of guilt.  Was it something I did after the child was born?  This study shows that changes start so early, they may have a sense of relief. "  

In the coverage from MSNBC, Geraldine Dawson was cited saying, "The goal is to be able to reduce the symptoms or even possibly prevent the syndrome from developing." 

ABC News quoted Dr. Nancy Minshew at the University of Pittsburgh who said, 'This adds to the evidence that autism develops on its own, so to speak, and not because parents did something or did not do something to cause autism.'

Autistic Children Have Different Guts

Stomach_acheManaging Editor's Note: We'd beg to differ on the autistic children also suffer from gastrointestinal disorders, but so far the connection, if any remains unclear but this is worth noting:

(Ivanhoe Newswire)-- An interesting observation has been made that many autistic children have a different kind of bacteria in their intestinal tract than non-autistic children do.

Brent Williams and colleagues at the Mailman School of Public Health at Columbia University found that bacteria belonging to the group Sutterella are one of the major populations of microorganisms living in the gut of some autistic children. Sutterella was not found in tissue samples from non-autistic children.

It is an enigma what the correlation is between the developmental disorder autism and the existence of Sutterella. Jorge Benach, Chairman of the Department of Microbiology at Stony Brook University and a reviewer of the report is quoted as saying, "Sutterella has been associated with gastrointestinal diseases below the diaphragm, and whether it's a pathogen or not is still not clear. It is not a very well-known bacterium."

Frequently, autistic children also suffer from gastrointestinal disorders, but so far the connection, if any remains unclear. Autism itself is still poorly understood.

"The relationship between different microorganisms and the host and the outcomes for disease and development is an exciting issue," Christine A. Biron, the Brintzenhoff Professor of Medical Science at Brown University and editor of the study was quoted as saying.

Abstract

BACKGROUND:

Autism may involve an autoimmune pathogenesis. Immunotherapy may have a role in autistic children who have brain auto-antibodies.

AIM:

This study aimed to investigate the frequency of serum antineuronal auto-antibodies, as indicators of the presence of autoimmunity to brain, in a group of autistic children. We are the first to measure the relationship between these antibodies and the degree of the severity of autism.

METHODS:

Serum antineuronal antibodies were measured, by indirect immunofluorescence technique, in 80 autistic children, aged between 6 and 12 years, in comparison to 80 healthy-matched children. The severity of autism was assessed by using the Childhood Autism Rating Scale.

RESULTS:

Autistic children had significantly higher percent positivity of serum antineuronal antibodies (62.5%) than healthy controls (5%), P<0.001. The frequency of the positivity of serum antineuronal antibodies was significantly higher in children with severe autism (87.5%) than children with mild to moderate autism (25%), P<0.001. Similarly, the frequency of the positivity of these antibodies was significantly higher in female children with autism (90%) than male autistic children (53.3%), P=0.001.

CONCLUSIONS:

Serum antineuronal antibodies were found in a subgroup of autistic children and they were significantly correlated to the severity of autism. Thus, autism may be, in part, one of the pediatric autoimmune neuropsychiatric disorders. Further wide-scale studies are warranted to shed light on the etiopathogenic role of antineuronal antibodies in autism. The role of immunotherapy in autistic patients, who are seropositive for antineuronal antibodies, should also be studied.

Abstract

CONTEXT:

Autism spectrum disorders (ASDs) have been suggested to represent the extreme end of a normal distribution of autisticlike traits (ALTs). However, the evidence of this notion is inconclusive.

OBJECTIVE:

To study whether there are similar genetic and/or environmental etiologies behind ASDs and ALTs.

DESIGN:

A nationwide twin study.

PARTICIPANTS:

Consenting parents of all Swedish twins aged 9 and 12 years, born between July 1, 1992, and December 31, 2001 (n = 19 208), were interviewed by telephone to screen for child psychiatric conditions, including ASDs.

MAIN OUTCOME MEASURES:

Two validated cutoffs for ASDs, 2 cutoffs encompassing the normal variation, and 1 continuous measure of ALTs were used with DeFries-Fulker extreme-end analyses and standard twin study methods.

RESULTS:

We discerned a strong correlation between the 4 cutoffs and the full variation of ALTs. The correlation was primarily affected by genes. We also found that the heritability for the 4 cutoffs was similar.

CONCLUSION:

We demonstrate an etiological similarity between ASDs and ALTs in the normal variation and, with results from previous studies, our data suggest that ASDs and ALTs are etiologically linked.

Maternal Characteristics and Hospital Policies as Risk Factors for Nonreceipt of Hepatitis B Vaccine in the Newborn Nursery

O'Leary, Sean T. MD, MPH*,†,‡; Nelson, Christina MD, MPH; Duran, Julie MPH‡,§

Supplemental Author Material

Background: A birth dose of hepatitis B vaccine (HBV) is a primary focus of the Advisory Committee on Immunization Practices' strategy to eliminate transmission of hepatitis B virus in the United States. We sought to assess the impact of maternal characteristics and hospital policy on the receipt of a birth dose of HBV.

Methods: A retrospective cohort study was performed using data from the 2008 Colorado birth registry. Hospital policy was assessed by state health department personnel. Univariate and multivariate logistic regression analyses were used to examine the association of maternal characteristics and hospital policy with nonreceipt of HBV.

Results: A total of 64,425 infants were identified in the birth cohort, of whom 61.6% received a birth dose of HBV. Higher maternal education and income were associated with nonreceipt of HBV (master's degree vs. eighth grade or less: adjusted odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.49–1.85; >$75,000 vs. <$15,000: adjusted OR = 1.21, 95% CI = 1.13–1.30). Lack of a hospital policy stipulating a universal birth dose strongly predicted nonreceipt of a birth dose of HBV (policy with no birth dose vs. policy with a birth dose: adjusted OR = 2.21, 95% CI = 2.13–2.30).

Conclusions: Maternal characteristics such as higher education and income are associated with nonreceipt of the HBV during the perinatal period. To effectively reduce risk of perinatal hepatitis B transmission, hospitals should stipulate that all infants are offered HBV and ensure that these policies are implemented and followed.

AofA Science Summary: possible link between the elevated serum levels of neurokinin A and anti-ribosomal P protein antibodies in children with autism

The possible link between the elevated serum levels of neurokinin A and anti-ribosomal P protein antibodies in children with autism.

Mostafa GAAl-Ayadhi LY.

Abstract

ABSTRACT:

BACKGROUND:

Neurogenic inflammation is orchestrated by a large number of neuropeptides. Tachykinins (substance P, neurokinin A and neurokinin B) are pro-inflammatory neuropeptides that may play an important role in some autoimmune neuroinflammatory diseases. Autoimmunity may have a role in the pathogenesis of autism in some patients. We are the first to measure serum neurokinin A levels in autistic children. The relationship between serum levels of neurokinin A and anti-ribosomal P protein antibodies was also studied.

METHODS:

Serum neurokinin A and anti-ribosomal P protein antibodies were measured in 70 autistic children in comparison to 48 healthy-matched children.

RESULTS:

Autistic children had significantly higher serum neurokinin A levels than healthy controls (P < 0.001). Children with severe autism had significantly higher serum neurokinin A levels than patients with mild to moderate autism (P < 0.001). Increased serum levels of neurokinin A and anti-ribosomal P protein antibodies were found in 57.1% and 44.3%, respectively of autistic children. There was significant positive correlations between serum levels of neurokinin A and anti-ribosomal P protein antibodies (P = 0.004).

CONCLUSIONS:

Serum neurokinin A levels were elevated in some autistic children and they were significantly correlated to the severity of autism and to serum levels of anti-ribosomal P protein antibodies. However, this is an initial report that warrants further research to determine the pathogenic role of neurokinin A and its possible link to autoimmunity in autism. The therapeutic role of tachykinin receptor antagonists, a potential new class of anti-inflammatory medications, should also be studied in autism.

Abstract PURPOSE:

: Autism spectrum disorders are the most common developmental disorders, affecting 1 in 165 Canadian children. Although the experiences of the caregivers of children with autism have been examined to some extent, a thorough investigation of the benefits of this experience is warranted.

METHODS:

: The lived experiences of 8 married female primary caregivers of children with autism were assessed through a phenomenological study involving background questionnaires and one-on-one, semistructured interviews. All recruited participants completed the study.

RESULTS:

: Benefits were found in all areas of questioning, including financial, social, familial, health, and employment implications, in addition to benefits arising from activities and involvements taken on as a result of raising a child with autism. The findings shed light on an unconventional aspect of the effects of raising a child with autism.

CONCLUSIONS:

: Costs to these women's experiences were not predominant, and benefits arising from the caregiving role lead to positive accounts of their lived experiences. Results have broader implications for the understanding of the primary caregiver situation and the improvement of interactions with individuals with these lived experiences. In this way, clinical nurse specialists may encourage and contribute to support systems that foster a positive experience for caregivers of children with autism spectrum disorder, the children they care for, and their families.

The War on Science – The British Medical Journal & Dr. Wakefield

BMJ GibberishBy Ed Arranga

In January 2011, the British Medical Journal (BMJ) published a blistering 3-part series (here, here, here) and an editorial (here) accusing Dr. Wakefield of committing fraud in his study of bowel disease. 

The tone is harsh, the articles lengthy and involved, the findings absolute, and the judgment final. Dr. Wakefield is a fraud. To top it off, it’s published in the British Medical Journal – one of the UK’s most prestigious journals. There’s only one problem. It’s a manufactured piece of gibberish with no basis in fact.

Dr. Wakefield is being attacked in an attempt to suppress science – specifically his Lancet study (here) that was published in 1998. Wakefield found bowel disease in children with autism spectrum disorder and raised questions about the safety of the MMR (measles, mumps, and rubella) vaccine. The study is valid and scientifically sound.

The British Medical Journal’s campaign to discredit Dr. Wakefield may be the greatest suppression of science episode ever attempted. It is estimated that over 150 million Americans were duped into believing the claims made against him.

The attacks on Dr. Wakefield are a crude reminder that there has always been conflict between those who serve science and those who want to censor it. Science advances at a cost, and the British Medical Journal has shown they are willing to pay any price – to sacrifice science itself – in order to declare victory on the battlefield of autism and vaccines.

Dr. Wakefield is a man of honor, principle, and integrity. He came to the US in 2004, as many scientists do, to continue his research without fear of reprisals. Seven years after leaving the UK – and 13 after his Lancet study – the British Medical Journal pursued Wakefield across the Atlantic in a campaign to silence him once and for all. Science be damned.

The British Medical Journal misjudged Dr. Wakefield’s commitment to science and picked a fight with the wrong guy.

Why Pick a Fight Based on a Lie?

Culture is a tricky thing. Did the British Medical Journal think it would just blow into town and tell a lie so big no one would notice? Did the editors seriously believe the same type of tabloid journalism that is standard practice in the UK would find a welcome home in the US? 

Obviously they did. The allegations, the character assassination, the sensational overblown trumpeting of “Wakefield the fraud,” and the claim of unbiased investigative journalism had, after all, been spoon fed to the British, with nary a hitch. The British public had been duped. Why not the Americans?

To any student of Anglo-American history, this was a risky venture. Americans are fiercely independent – the British not so much. We don’t take kindly to other nations targeting Americans. Europe, on the other hand, is a swirling pot of nations, used to shooting at each other for centuries.

The greatest difference between the US and UK lies in how Americans fight to protect their freedoms. It’s a strange and somewhat dangerous concept to outsiders looking in. But it’s a value that shapes our thoughts and actions from cradle to grave.

We take our freedoms seriously, particularly the freedom of speech. The BMJ’s campaign to silence Wakefield flies in the face of what this country holds most dear.

Do aluminum vaccine adjuvants contribute to the rising prevalence of autism?

Abstract

Autism spectrum disorders (ASD) are serious multisystem developmental disorders and an urgent global public health concern. Dysfunctional immunity and impaired brain function are core deficits in ASD. Aluminum (Al), the most commonly used vaccine adjuvant, is a demonstrated neurotoxin and a strong immune stimulator. Hence, adjuvant Al has the potential to induce neuroimmune disorders. When assessing adjuvant toxicity in children, two key points ought to be considered: (i) children should not be viewed as "small adults" as their unique physiology makes them much more vulnerable to toxic insults; and (ii) if exposure to Al from only few vaccines can lead to cognitive impairment and autoimmunity in adults, is it unreasonable to question whether the current pediatric schedules, often containing 18 Al adjuvanted vaccines, are safe for children? By applying Hill's criteria for establishing causality between exposure and outcome we investigated whether exposure to Al from vaccines could be contributing to the rise in ASD prevalence in the Western world. Our results show that: (i) children from countries with the highest ASD prevalence appear to have the highest exposure to Al from vaccines; (ii) the increase in exposure to Al adjuvants significantly correlates with the increase in ASD prevalence in the United States observed over the last two decades (Pearson r=0.92, p<0.0001); and (iii) a significant correlation exists between the amounts of Al administered to preschool children and the current prevalence of ASD in seven Western countries, particularly at 3-4months of age (Pearson r=0.89-0.94, p=0.0018-0.0248). The application of the Hill's criteria to these data indicates that the correlation between Al in vaccines and ASD may be causal. Because children represent a fraction of the population most at risk for complications following exposure to Al, a more rigorous evaluation of Al adjuvant safety seems warranted.

Abstract

Infection by RNA virus induces oxidative stress in host cells. Accumulating evidence suggests that cellular redox status plays an important role in regulating viral replication and infectivity. In this study, experiments were performed to determine whether the thiol antioxidant glutathione (GSH) blocked influenza viral infection in cultures of Madin-Darby canine kidney cells or human small airway epithelial cells. Protection against production of active virus particles was observed at a low (0.05-0.1) multiplicity of infection (MOI). GSH inhibited expression of viral matrix protein and inhibited virally induced caspase activation and Fas upregulation. In BALB/c mice, inclusion of GSH in the drinking water decreased viral titer in both lung and trachea homogenates 4 d after intranasal inoculation with a mouse-adapted influenza strain A/X-31. Together, the data suggest that the thiol antioxidant GSH has an anti-influenza activity in vitro and in vivo. Oxidative stress or other conditions that deplete GSH in the epithelium of the oral, nasal, and upper airway may, therefore, enhance susceptibility to influenza infection.

Abstract AIM:

The aim of this study was to determine whether GSH-C4, a hydrophobic glutathione derivative, affects in vitro and in vivo influenza virus infection by interfering with redox-sensitive intracellular pathways involved in the maturation of viral hemagglutinin (HA).

RESULTS:

GSH-C4 strongly inhibited influenza A virus replication in cultured cells and in lethally infected mice, where it also reduced lung damage and mortality. In cell-culture studies, GSH-C4 arrested viral HA folding; the disulfide-rich glycoprotein remained in the endoplasmic reticulum as a reduced monomer instead of undergoing oligomerization and cell plasma-membrane insertion. HA maturation depends on the host-cell oxidoreductase, protein disulfide isomerase (PDI), whose activity in infected cells is probably facilitated by virus-induced glutathione depletion. By correcting this deficit, GSH-C4 increased levels of reduced PDI and inhibited essential disulfide bond formation in HA. Host-cell glycoprotein expression in uninfected cells was unaffected by glutathione, which thus appears to act exclusively on glutathione-depleted cells.

INNOVATION:

All currently approved anti-influenza drugs target essential viral structures, and their efficacy is limited by toxicity and by the almost inevitable selection of drug-resistant viral mutants. GSH-C4 inhibits influenza virus replication by modulating redox-sensitive pathways in infected cells, without producing toxicity in uninfected cells or animals. Novel anti-influenza drugs that target intracellular pathways essential for viral replication ("cell-based approach") offer two important potential advantages: they are more difficult for the virus to adapt to and their efficacy should not be dependent on virus type, strain, or antigenic properties.

CONCLUSION:

Redox-sensitive host-cell pathways exploited for viral replication are promising targets for effective anti-influenza strategies.

 

Autism and PANDAS

AUTISM PANDAS  teresa conrick- graphic adriana gamondes
By Teresa Conrick

My daughter, Megan's recent diagnosis of an autoimmune condition coupled with an abnormal EEG are big, red flags that help illustrate why she is so ill.  Finding that out hardly ends my journey for more answers to help improve her health and her life.  The disturbing behaviors and symptoms of vocal tics, dilated pupils, agitation, enuresis, and OCD are a barometer of brain dysfunction.  Add in estrogen-induced seizures that developed at age seventeen in tandem to her autoimmune diagnosis and that may be another clue.  As a result, I have been exploring more of the issues that connect her to those children who have a P.A.N.D.A.S. (Pediatric Autoimmune Neuropsychiatric Diagnosis Associated with Streptococcal Infections) diagnosis as Megan has had numerous bouts of Strep and other infections that exploded into severe movement and vocal tics over the years.  Her original regression into an autism diagnosis slowly happened after vaccinations along with increasing viral and bacterial infections as a toddler, then an acute rash, fever and loss of language after her MMR vaccine.  We now seem to be in the land of chronic waxing and waning of symptoms and the most sobering part --- we are not alone.


More parents are finding each other and connecting via their child's medical issues.  Autism and P.A.N.D.A.S. may be cousins of a similar origin as there is overlap in symptoms, both behavioral and medical.  A good place to learn more about P.A.N.D.A.S. is this informative site.  A warrior mother in the P.A.N.D.A.S. trenches, Diana Pohlman, developed it in 2009 as she decided to bring parents, research and researchers together to investigate why their children were becoming acutely affected by a monster that Streptococcus bacteria seemed to awaken.  Like so many of us, she saw her son regress into an immune illness that severely affected his mood, behaviors, functioning -- his life.  More and more children each year seem to be developing tics, severe anxiety, obsessive compulsions, involuntary movements and psychiatric issues, not randomly, but due to an infection affecting the brain.  It is usually Streptococcus, an evil little bacteria that these mothers despise, because it is stealing their children.  So Autism parents and P.A.N.D.A.S.parents are beginning to link arms to tackle both cause and cure. As it states on Diana's website above, "Parents Helping Parents," is a key for many families to compare medical issues and treatments.

P.A.N.D.A.S. is a medical diagnosis yet many still do not understand it thus, there is confusion on its causation, how to diagnose it and then appropriate treatments.  We in the trenches of Autism are familiar with these issues as we have been dealing with them for too many years.  Our toddler or child becomes ill, either through an infection or after vaccination and there is a regression in skills. Odd, perseverative and debilitating behaviors creep in.  Life forever changes.  Doctors dismiss the cause and labels are given.  Precious time is lost then more medical symptoms, more labels. A stinging reality -- lack of proper medical treatments cause worsening behaviors.  This continues to happen at an alarming rate.


Some significant research continues to evolve with P.A.N.D.A.S., and the names Cunningham, Swedo and Murphy are becoming instrumental in connecting the hated bacteria to the hosts they have kidnapped.  Another interesting development was the apparent acknowledgement from Dr. Tom Insel that P.A.N.D.A.S. was indeed a real, medical illness. For those who do not know him, Dr. Insel is Director of the National Institute of Mental Health (NIMH), the component of the National Institutes of Health "charged with generating the knowledge needed to understand, treat, and prevent mental disorders", per the website,  including Autism and now also, P.A.N.D.A.S.

According to Science magazine writer Jon Cohen in an article entitled "Controversial CFS Researcher Arrested and Jailed", Dr. Mikovits was arrested on "felony charges that she is a fugitive from justice." 

Dr. Mikovits was the research director at the Whittemore Peterson Institute for Neuro-Immune Diseases in Reno, Nevada until she was fired on September 29, 2011.  Upon being fired she returned to her home in southern California where her husband was staying.  On November 4, the WPI filed suit against Dr. Mikovits, claiming she had kept lab notebooks and other information in her laptop, flash drives, and in her personal e-mail account.  A preliminary injunction on this matter was to be held in Nevada's Second District Judicial Court on November 22, 2011.

Lois Hart, an attorney for Dr. Mikovits denies that her client has any notebooks or other proprietary items.  Age of Autism must note the unusual circumstances which would cause the WPI to arrest Dr. Mikovits when a hearing on the preliminary injunction had already been set.  After her arrest on Friday, November 18, Dr. Mikovits was not allowed to post bail and has spent the weekend in jail.  A hearing for Dr. Mikovits in Ventura, California will take place on Tuesday, November 22 at the Ventura County Government Center, Hall of Justice, Room 13 at 1:30.  She remains in jail at the time of this writing.

The hearing in California will prevent Dr. Mikovits from attending the hearing in Nevada.

Abstract

Interactions between genetic and environmental risk factors underlie a number of neuropsychiatric disorders, including schizophrenia (SZ) and autism (AD). Due to the complexity and multitude of the genetic and environmental factors attributed to these disorders, recent research strategies focus on elucidating the common molecular pathways through which these multiple risk factors may function. In this study, we examine the combined effects of a haplo-insufficiency of glutamate carboxypeptidase II (GCPII) and dietary folic acid deficiency. In addition to serving as a neuropeptidase, GCPII catalyzes the absorption of folate. GCPII and folate depletion interact within the one-carbon metabolic pathway and/or of modulate the glutamatergic system. Four groups of mice were tested: wildtype, GCPII hypomorphs, and wildtypes and GCPII hypomorphs both fed a folate deficient diet. Due to sex differences in the prevalence of SZ and AD, both male and female mice were assessed on a number of behavioral tasks including locomotor activity, rotorod, social interaction, pre-pulse inhibition, and spatial memory. Wildtype mice of both sexes fed a folic acid deficient diet showed motor coordination impairments and cognitive deficits, while social interactions were decreased only in males. GCPII mutant mice of both sexes also exhibited reduced social propensities. In contrast, all folate-depleted GCPII hypomorphs performed similarly to untreated wildtype mice, suggesting that reduced GCPII expression and folate deficiency are mutually protective. Analyses of folate and neurometabolite levels associated with glutamatergic function suggest several potential mechanisms through which GCPII and folate may be interacting to create this protective effect. © 2011 Wiley Periodicals, Inc.

Odds Are It's Wrong: Science News on Statistics and Medical Care

StatsManaging Editor's Note: Thank you to Jean B. for sending me this article from Science News.

For better or for worse, science has long been married to mathematics. Generally it has been for the better. Especially since the days of Galileo and Newton, math has nurtured science. Rigorous mathematical methods have secured science’s fidelity to fact and conferred a timeless reliability to its findings.

During the past century, though, a mutant form of math has deflected science’s heart from the modes of calculation that had long served so faithfully. Science was seduced by statistics, the math rooted in the same principles that guarantee profits for Las Vegas casinos. Supposedly, the proper use of statistics makes relying on scientific results a safe bet. But in practice, widespread misuse of statistical methods makes science more like a crapshoot.

It’s science’s dirtiest secret: The “scientific method” of testing hypotheses by statistical analysis stands on a flimsy foundation. Statistical tests are supposed to guide scientists in judging whether an experimental result reflects some real effect or is merely a random fluke, but the standard methods mix mutually inconsistent philosophies and offer no meaningful basis for making such decisions. Even when performed correctly, statistical tests are widely misunderstood and frequently misinterpreted. As a result, countless conclusions in the scientific literature are erroneous, and tests of medical dangers or treatments are often contradictory and confusing.

Replicating a result helps establish its validity more securely, but the common tactic of combining numerous studies into one analysis, while sound in principle, is seldom conducted properly in practice.

Experts in the math of probability and statistics are well aware of these problems and have for decades expressed concern about them in major journals. Over the years, hundreds of published papers have warned that science’s love affair with statistics has spawned countless illegitimate findings. In fact, if you believe what you read in the scientific literature, you shouldn’t believe what you read in the scientific literature.

“There is increasing concern,” declared epidemiologist John Ioannidis in a highly cited 2005 paper in PLoS Medicine, “that in modern research, false findings may be the majority or even the vast majority of published research claims.”

Ioannidis claimed to prove that more than half of published findings are false, but his analysis came under fire for statistical shortcomings of its own. “It may be true, but he didn’t prove it,” says biostatistician Steven Goodman of the Johns Hopkins University School of Public Health. On the other hand, says Goodman, the basic message stands. “There are more false claims made in the medical literature than anybody appreciates,” he says. “There’s no question about that.”

Nobody contends that all of science is wrong, or that it hasn’t compiled an impressive array of truths about the natural world. Still, any single scientific study alone is quite likely to be incorrect, thanks largely to the fact that the standard statistical system for drawing conclusions is, in essence, illogical. “A lot of scientists don’t understand statistics,” says Goodman. “And they don’t understand statistics because the statistics don’t make sense.”

Abstract

Autism is a complex genetic disorder with multiple etiologies whose molecular genetic basis is not fully understood. Although a number of rare mutations and dosage abnormalities are specific to autism, these explain no more than 10% of all cases. The high heritability of autism and low recurrence risk suggests multifactorial inheritance from numerous loci but other factors also intervene to modulate risk. In this study, we examine the effect of birth rank on disease risk which is not expected for purely hereditary genetic models.We analyzed the data from three publicly available autism family collections in the USA for potential birth order effects and studied the statistical properties of three tests to show that adequate power to detect these effects exist. We detect statistically significant, yet varying, patterns of birth order effects across these collections. In multiplex families, we identify V-shaped effects where middle births are at high risk; in simplex families, we demonstrate linear effects where risk increases with each additional birth. Moreover, the birth order effect is gender-dependent in the simplex collection. It is currently unknown whether these patterns arise from ascertainment biases or biological factors. Nevertheless, further investigation of parental age-dependent risks yields patterns similar to those observed and could potentially explain part of the increased risk. A search for genes considering these patterns is likely to increase statistical power and uncover novel molecular etiologies.

XMRV (HGRV) is Not Dead - The Rituximab Story

Rituximab-rituxan-715856By Kent Heckenlively, Esq.

I think that we have not cared for people with ME (myalgic encephelomyelitis, otherwise known as chronic fatigue syndrome) to a great enough extent.  I think it is correct to say that we have not established proper health care services for these people, and I regret that." - Apology from the Norwegian Directorate of Health on publication of a study showing that the cancer drug rituximab is effective in the treatment of chronic fatigue syndrome/ME.

What was reason for this unprecedented apology from the public health authorities in Norway?

It was the publication of a study which showed that the drug rituximab improved the health of 10 of 15 patients (67%) with chronic fatigue syndrome/ME and that 2 of the 15 patients given the drug staged a complete recovery from their condition.  You can read about the study in Medscape.

Why is this important to the autism community?

It's important because chronic fatigue syndrome/ME and autism share many common clinical indicators, including immune disregulation, increased oxidative stress, heavy metal retention, co-infection by other pathogens, and mitichondrial insufficiency.  What is effective in treating chronic fatigue syndrome/ME may end up having some relevance to treatments for autism.  I have written before about my daughter with autism having tested positive for XMRV.  You can read my previous article for background on XMRV.

The researchers I have spoken with about XMRV and autism have told me their suspicion that the retrovirus likes to enter B cells which have the CD20 receptor.  They also suspect that it isn't the retrovirus itself which is doing the harm, but the toxins or auto-antibodies which are produced in response to the retrovirus.  Rituximab specifically targets those B cells which have the CD20 receptor.  It is a very targeted type of chemotherapy, although it is not without significant risks.

B cells are part of the immune system, but when they go haywire they may cause cancer, or diseases like rheumatoid arthritis.  Rituximab is approved for the treatment of rheumatoid arthritis and many types of lymphoma.

The question of why rituximab's depletion of B cells helps those with chronic fatigue syndrome/ME remains unexplained.  The researchers specifically noted they had searched for XMRV and not found evidence of its presence, but that touches on the greater issue of whether the currently validated test for XMRV is accurate.
