"A first-ever vaccine created by University of Guelph researchers for gut bacteria common in autistic children may also help control some autism symptoms. The groundbreaking study by Brittany Pequegnat and Guelph chemistry professor Mario Monteiro appears this month in the journal Vaccine.
"They developed a carbohydrate-based vaccine against the gut bug Clostridium bolteae.
"C. bolteae is known to play a role in gastrointestinal disorders, and it often shows up in higher numbers in the GI tracts of autistic children than in those of healthy kids.
"More than 90 per cent of children with autism spectrum disorders suffer from chronic, severe gastrointestinal symptoms. Of those, about 75 per cent suffer from diarrhea, according to current literature. Little is known about the factors that predispose autistic children to C. bolteae,' said Monteiro. Although most infections are handled by some antibiotics, he said, a vaccine would improve current treatment.
"'This is the first vaccine designed to control constipation and diarrhea caused by C. bolteae and perhaps control autism-related symptoms associated with this microbe,' he said.
"Autism cases have increased almost sixfold over the past 20 years, and scientists don't know why. Although many experts point to environmental factors, others have focused on the human gut.
"Some researchers believe toxins and/or metabolites produced by gut bacteria, including C. bolteae, may be associated with symptoms and severity of autism, especially regressive autism."
So I guess all those experts at the Mayo Clinic and at the AAP
who just four years ago said , there is no association between bowel disease and autism have egg all over their faces.
"The journal Pediatrics had the story, Incidence of Gastrointestinal Symptoms in Children With Autism: A Population-Based Study which reported on a study from the Mayo Clinic:" No significant associations were found between autism case status and overall incidence of gastrointestinal symptoms or any other gastrointestinal symptom category.
"Conclusion: As constipation and feeding issues/food selectivity often have a behavioral etiology, data suggest that a neurobehavioral rather than a primary organic gastrointestinal etiology may account for the higher incidence of these gastrolintestinal symptoms in children with autism."
This would also include Dr. Nancy at NBC: Autism and Gut Issues: But Dr. Nancy Said There's No Connection!
So why is there more bowel disease in ASD kids? Why are you only looking for a vaccine to control symptoms and searching for causation? It's probably because the money's in treatment, not prevention.
