Histopathologist from the Lancet study Rebuffs Brian Deer’s Article in British Medical Journal
By John Stone
A letter in on-line BMJ today from, Susan E Davies, one of the signatory histopathologists to the Lancet paper (HERE), rebuts Brian Deer’s imputation that there was anything amiss with the interpretation of the histopathology results in the study. This should finally knock on the head the claim made by Deer first in the Sunday Times in February 2009 that Andrew Wakefield had manipulated the results of the biopsy tests for his own purposes (HERE & HERE ).
Deer wrote in his article published a fortnight ago (HERE):
“The lead pathologist for the Wakefield project, and an author of the now retracted paper, was Susan Davies, now at Addenbrooke’s Hospital, Cambridge. At weekly meetings with paediatricians, the unexceptional results were confirmed. For four of the 12 she made additional notes recording the position more bluntly: "no abnormality detected". “
Deer based his report on evidence given by Davies to the GMC hearing in 2007 but it now looks clear that he put too much emphasis on isolated statements. Instead, Davies’s letter substantially corroborates the account of the matter that Wakefield gave in his complaint to the UK Press Complaints Commission (HERE). This is the text of Davies’s letter (HERE):-
Caution in assessing histopathological opinions. 30 April 2010
As one of the pathologists in question, I wish to respond to some of the issues raised in the recent article by Brian Deer(1), and accompanying editorial by Nick Wright(2), on the histopathological aspects of autistic enterocolitis. There is some misrepresentation of my involvement and lack of understanding of the process in studies involving histopathology.
Firstly, at the time in question I was working solely for the NHS and acted as the key pathologist for the clinical gastroenterology paediatric team. I was not the lead pathologist for this, or any other Wakefield project.
