A Comparison of Urinary Mercury between Children with Autism Spectrum Disorders and Control Children

16 Feb

Researchers are still looking at the question of whether autism is caused by mercury intoxication. One of the measures used in the past is to check the mercury content in the urine of autistic and non autistic children. Claims have been made that autistic children are “poor excretors” of mercury. This is defined as “more mercury in the urine than other children” or “less mercury in the urine of other children”.

A group of researchers from the UK and US have tested a group of autistic children, special needs non autistic children, siblings and regular school children. What did they find? No difference.

Background

Urinary mercury concentrations are used in research exploring mercury exposure. Some theorists have proposed that autism is caused by mercury toxicity. We set out to test whether mercury concentrations in the urine of children with autism were significantly increased or decreased compared to controls or siblings.

Methods

Blinded cohort analyses were carried out on the urine of 56 children with autism spectrum disorders (ASD) compared to their siblings (n = 42) and a control sample of children without ASD in mainstream (n = 121) and special schools (n = 34).
Results

There were no statistically significant differences in creatinine levels, in uncorrected urinary mercury levels or in levels of mercury corrected for creatinine, whether or not the analysis is controlled for age, gender and amalgam fillings.

Conclusions

This study lends no support for the hypothesis of differences in urinary mercury excretion in children with autism compared to other groups. Some of the results, however, do suggest further research in the area may be warranted to replicate this in a larger group and with clear measurement of potential confounding factors.

There were outliers of high mercury content in the special needs children (both autistic and non autistic). Expect those promoting the autism/mercury connection to focus on those children and to build connections between the funding agencies and pharmaceutical companies.

Attorney for Prof. Walker-Smith: alleged link between MMR and autism utterly disproved

14 Feb

Prof. John Walker-Smith was a colleague of Andrew Wakefield, a co-author on the no-retracted 1998 Lancet paper and shared the same fate as Mr. Wakefield after the General Medical Council Hearings: he was struck off the medical register. Prof. Walker-Smith has appealed (Mr. Wakefield did not). A few news stories have come up about this appeal. In Doctor struck off over MMR controversy appeals against ruling, the Guardian notes:

Prof John Walker-Smith tells high court he was denied a fair hearing before he was struck off by the General Medical Council

Many are looking to this appeal for vindication of Mr. Wakefield and his theories on MMR being linked to and causal in autism. Prof. Walker-Smith’s attorney appears to have made a rather clear statement to the contrary:

Miller said it had been important that the disciplinary panel “separate out research from the clinical medicine – but that was a task that appeared to be beyond them”.

The judge asked Miller whether the alleged link between MMR and the vaccine “has now been utterly disproved” in the opinion of “respectable medical opinion”.

Miller said that was “exactly” the position.

edit to add:

I took the statement “The judge asked Miller whether the alleged link between MMR and the vaccine “has now been utterly disproved” ” to be a mistaken report by the Guardian because, as written, it does not make sense. My own interpretation was that the actual question was whether the MMR and *autism* was the point. However, I should have made that assumption very clear in the above piece and I apologize for that. I have written the paper as well as some other people who might be able to clarify the statement.

The Panic Virus: now in paperback

9 Feb

The Panic Virus came out just over a year ago. We discussed it on Left Brain/Right Brain (here and here). As one who has spent a great deal of time reading and writing about the autism/vaccine discussion, I found the book to be extremely well researched and very well written.

The author, Seth Mnookin, now teaches science writing at the Massachusetts Institute of Technology (MIT) and writes for the PLoS blogs.

Here is a blurb on the book:

WHO DECIDES WHICH FACTS ARE TRUE?

In 1998 Andrew Wakefield, a British gastroenterologist with a history of self-promotion, published a paper with a shocking allegation: the measles-mumps-rubella vaccine might cause autism. The media seized hold of the story and, in the process, helped to launch one of the most devastating health scares ever. In the years to come Wakefield would be revealed as a profiteer in league with class-action lawyers, and he would eventually lose his medical license. Meanwhile one study after another failed to find any link between childhood vaccines and autism.

Yet the myth that vaccines somehow cause developmental disorders lives on. Despite the lack of corroborating evidence, it has been popularized by media personalities such as Oprah Winfrey and Jenny McCarthy and legitimized by journalists who claim that they are just being fair to “both sides” of an issue about which there is little debate. Meanwhile millions of dollars have been diverted from potential breakthroughs in autism research, families have spent their savings on ineffective “miracle cures,” and declining vaccination rates have led to outbreaks of deadly illnesses like Hib, measles, and whooping cough. Most tragic of all is the increasing number of children dying from vaccine-preventable diseases.

In The Panic Virus Seth Mnookin draws on interviews with parents, public-health advocates, scientists, and anti-vaccine activists to tackle a fundamental question: How do we decide what the truth is? The fascinating answer helps explain everything from the persistence of conspiracy theories about 9/11 to the appeal of talk-show hosts who demand that President Obama “prove” he was born in America.

The Panic Virus is a riveting and sometimes heart-breaking medical detective story that explores the limits of rational thought. It is the ultimate cautionary tale for our time.

Autism SA battles for funds

9 Feb

For most within the autism communities, I suspect that charities are chosen with great care. Whether under- or un-employed autistic or a parent concerned about providing for a child, each dollar counts to many of us. But if you will allow me to suggest a charity to consider: Autism South Africa

I was reminded of Autism SA while reading another blog. The Simons Foundation SFARI blog has a discussion of a recent study on Autism in Africa. The study they focus on is Excess of non-verbal cases of autism spectrum disorders presenting to orthodox clinical practice in Africa – a trend possibly resulting from late diagnosis and intervention. On many levels this study is important to me. But, what I’m writing about now is based on a comment:

Things are not improving fast enough. South Africa’s main autism charity, Autism SA, has only two months left if it doesn’t get funds to continue. http://www.sowetanlive.co.za/news/2012/02/08/autism-sa-battles-for-funds The majority of doctors, psychologists and other healthcare practitioners in South Africa and the rest of Africa are not trained to diagnose autism.

Autism South Africa’s website includes a link to how to donate. I just sent a few Rand their way, it’s pretty easy.

A Multisite Study of the Clinical Diagnosis of Different Autism Spectrum Disorders

5 Feb

This study came out towards the end of last year. Given the current interest in the DSM-5 diagnostic criteria and how they may impact the numbers of individuals diagnosed with PDD-NOS and Asperger syndrome, this seems timely.

The study had a large number of authors. As a multi-site study, this is not surprising. The lead author is Cathy Lord. She is part of the DSM-5 work group on neurodevelopmental disorders.

The author list and the abstract are below. I’ll pull the conclusion from the abstract out for now:

Clinical distinctions among categorical diagnostic subtypes of autism spectrum disorders were not reliable even across sites with well-documented fidelity using standardized diagnostic instruments. Results support the move from existing subgroupings of autism spectrum disorders to dimensional descriptions of core features of social affect and fixated, repetitive behaviors, together with characteristics such as language level and cognitive function

To put it simply (and with less precision, but let’s go with this): Whether one is diagnosed as Asperger, PDD-NOS or Autistic Disorder is more dependent on where one is diagnosed than what one’s scores are on the tests given.

Seems likely this is part of the reason why there’s a move to incorporate all ASD’s under a single label.

The “lines” between autistic disorder, PDD-NOS and Asperger syndrome are blurred to say the least.

Here is the full author list:

And here the abstract:

CONTEXT:

Best-estimate clinical diagnoses of specific autism spectrum disorders (autistic disorder, pervasive developmental disorder-not otherwise specified, and Asperger syndrome) have been used as the diagnostic gold standard, even when information from standardized instruments is available.

OBJECTIVE:

To determine whether the relationships between behavioral phenotypes and clinical diagnoses of different autism spectrum disorders vary across 12 university-based sites.

DESIGN:

Multisite observational study collecting clinical phenotype data (diagnostic, developmental, and demographic) for genetic research. Classification trees were used to identify characteristics that predicted diagnosis across and within sites.

SETTING:

Participants were recruited through 12 university-based autism service providers into a genetic study of autism.

PARTICIPANTS:

A total of 2102 probands (1814 male probands) between 4 and 18 years of age (mean [SD] age, 8.93 [3.5] years) who met autism spectrum criteria on the Autism Diagnostic Interview-Revised and the Autism Diagnostic Observation Schedule and who had a clinical diagnosis of an autism spectrum disorder. Main Outcome Measure Best-estimate clinical diagnoses predicted by standardized scores from diagnostic, cognitive, and behavioral measures.

RESULTS:

Although distributions of scores on standardized measures were similar across sites, significant site differences emerged in best-estimate clinical diagnoses of specific autism spectrum disorders. Relationships between clinical diagnoses and standardized scores, particularly verbal IQ, language level, and core diagnostic features, varied across sites in weighting of information and cutoffs.

CONCLUSIONS:

Clinical distinctions among categorical diagnostic subtypes of autism spectrum disorders were not reliable even across sites with well-documented fidelity using standardized diagnostic instruments. Results support the move from existing subgroupings of autism spectrum disorders to dimensional descriptions of core features of social affect and fixated, repetitive behaviors, together with characteristics such as language level and cognitive function.

Transcripts from the GMC hearings

2 Feb

With the defamation suit by Mr. Wakefield filed in Texas there is the strong possibility that the discussions will ensue again about what actually happened during Mr. Wakefield’s research at the Royal Free hospital. The one record of this is in the transcripts for the GMC hearings. These can be found online in a few places (casewatch and Sheldon 101’s blog Vaccines Work, for example). These are useful resources but somewhat cumbersome. Most people are not going to download a file to check a quote in context. And context can be very important, as we’ve seen here on Left Brain/ Right Brain where previous discussions by Mr. Wakefield’s supporters often involved pulling quotes out of context.

I don’t want to clutter this site with the transcripts, but I do want them in a place where internet search engines can find them and people can easily link and check quotes. So I am now uploading them to a new blog. It should take a few days to get the transcripts online in this format. About 30 days worth are up now.

In doing so I re-read some of the pages. One of the best examples of what happened is covered on Day 28. This is the day when the mother of Child 12 (last of the 12 children in the Lancet study) testified.

This one day’s testimony addresses many of the discussion topics which come up repeatedly in online discussions:

1) Parents of the Lancet Children were not prevented from testifying at the GMC.

2) She was the only one who did testify. She was the only one called by the GMC. The defense appears to have not called any of the parents.

3) Mr. Wakefield’s attorney declined the opportunity to even cross examine this parent.

4) The idea that Mr. Wakefield only reported what parents told him isn’t well supported by the evidence. Rather, there is a very circular route for the idea that the MMR causes autism. Mr. Wakefield and Mr. Barr (the attorney working on the litigation) were in contact with this parent multiple times before the child was seen at the Royal Free.

5) Some of the children in the Lancet study were registered with Legal Aid at the time of the study, and well before the Lancet paper was published.

6) The idea that the children were referred through normal channels is not accurate. While this child was referred through general practitioners, there was much contact between the mother, Mr. Wakefield and the attorney before that. One letter from the attorney makes it clear that they expressly told the parents to be sure to get the GP referral.

7) The idea that this work was not a research study isn’t really accurate. Mrs. 12 repeatedly gives her impression that they were involved in a research study.

Yes, this has all been covered before. Unfortunately, I fear this will all be covered repeatedly as this new case works its way through the court.

With that, here are some excerpts from the Day 28 testimony. Which you can check in context.

Q I think it is right that at around the same time, as well as that contact with Dr Wakefield, did you also have some contact with a firm of solicitors called Dawbarns?
A Yes, that is right.

Q Can you tell us how that came about. Why did you get in touch with them?
A The same mother told me about them as well.

Q What was your understanding of what they were doing?
A They were trying to really put a stop to the MMR vaccine being used and obviously to stop any damage that was being done to children.

Emphasis added. Mrs. 12 thought that Dawbarns “were trying to really put a stop to the MMR vaccine being used”.

After contacting the lawyers, she received a letter. This is dated 18 July 1996. Her son wasn’t seen at the Royal Free until 18 October, 1996, three months later:

“Dear [Mrs 12],

Thank you for contacting us regarding the MMR vaccination. We are investigating a number of vaccine damage cases and are also (with Messrs Freeth Cartwright Hunt Dickens of Nottingham) co-ordinating and managing the Mumps Measles and Rubella cases on behalf of the Legal Aid Board for the whole country. Recently the Legal Aid Board has also extended our contract to investigate claims following the Government’s measles/rubella vaccination campaign in the autumn of 1994.

To give you an idea of our work I enclose an information pack which consists of a copy of a fact sheet which we have produced on the MMR vaccine and a fact sheet on ourselves.

We have built up a considerable volume of evidence that vaccines can cause injury to children, and we are hoping to take compensation claims to court. See the fact sheets for more information. Legal Aid is now being granted in vaccine damage cases where we can show a close link up in time between the vaccine being administered and the onset of recognised side effects. In claims being brought on behalf of children the Legal Aid Office does not take into account the finances of the parents, but there are sometimes difficulties in obtaining legal aid …”

She was supplied with a “fact sheet” written by Mr. Wakefield. No contamination of the study there, right? In the Lancet he’s just reporting what the parents told him. No mention of the issue of the parents being supplied with a “fact sheet” to guide them.

Richard Barr (the attorney managing the litigation effort and teamed with Andrew Wakefield) wrote her on 14 August 1996

“We are also in touch with other experts and together they are hoping to establish a link between the vaccine, inflammatory bowel disease and autism. There is a clear cut biological mechanism for linking the two conditions. I suggest it might be worth your while to contact Dr Wakefield. If you would like me to do so I will be happy to make the introduction for you. May I have permission to send him a copy of the statement that I have prepared for [Child 12]?”

They are hoping to establish a link and “there is a clear cut biological mechanism for linking the two conditions [bowel disease and autism]”. Two months before being seen at the Royal Free she is informed about the effort to link MMR with autism and bowel disease and the idea that autism and bowel disease are linked.

Clearly any study reporting “what the parents told us” is contaminated at this point.

If you think the study could be salvaged, even with this level of contamination, here is a discussion of the fact sheet supplied to the parents as mentioned above:

Q The next document was a fact sheet, and that apparently comes from the Royal Free Hospital School of Medicine, as you will see at the top of the page. If I can just run through what some of that says, it is headed,

“Inflammatory Bowel Disease, measles virus and measles vaccination.

What is inflammatory Bowel Disease (IBD)?

IBD comprises 2 conditions that have many similarities. Crohn’s disease and ulcerative colitis. Crohn’s disease may affect any part of the bowel, from mouth to anus, whereas ulcerative colitis affects the large bowel only. Many people now believe that these two conditions are part of a single spectrum of intestinal disease. IBD is often difficult to diagnose in children, especially Crohn’s disease, and this may lead to a delay in diagnosis with frustration for parents, doctors and, in particular, the affected children.

What is the link with measles and measles vaccine?

Measles virus was put forward as a possible cause of Crohn’s disease in 1989. The dramatic rise in the incidence of inflammatory bowel disease in developed countries over the last 30 years, in the face of live measles vaccination, also suggested a link between the vaccine and the disease.

Several groups from around the world have now identified measles virus in tissues affected by Crohn’s disease and an immune response to measles virus in the blood of patients with Crohn’s disease and ulcerative colitis. Early exposure to measles virus appears to be a major risk factor for developing Crohn’s disease later in life, and one study recently linked live measles vaccine to both Crohn’s disease and ulcerative colitis. Several new studies are currently underway that are designed to clarify the association between measles vaccination and inflammatory bowel disease. Although no studies have formally examined the issue, we have been aware of a large number of new cases of childhood IBD following the MR revaccination campaign in November 1994”.

Then the fact sheet sets out what you would look for (and what you should do: contact Andrew Wakefield):

Q The next document was a fact sheet, and that apparently comes from the Royal Free Hospital School of Medicine, as you will see at the top of the page. If I can just run through what some of that says, it is headed,

“Crohn’s disease. The symptoms and signs of Crohn’s disease in childhood are often insidious and non-specific and may lead to a delay in diagnosis. Intestinal symptoms include mouth ulcers, cramping abdominal pains, loss of appetite, diarrhoea with or without blood and problems in the anal region, including skin tags, tears or abscess formation. However, children commonly present with weight loss and failure to thrive as the only indications that they may have Crohn’s disease. But be aware, unexplained joint paints, sore eyes and skin rashes can also be the presenting symptoms of Crohn’s disease.

Ulcerative colitis is often more clear-cut, with diarrhoea, urgency and blood and mucus mixed in with the stools. Again, growth failure and symptoms such as joint pain may precede the intestinal problems.

What should we do?

If you suspect that your child has inflammatory bowel disease, prompt referral to a specialist centre is essential. Either the diagnosis will be excluded and your mind put at rest, or it will be confirmed and the appropriate treatment instituted. As a first step you should contact Dr Andrew Wakefield at the Royal Free Hospital”,

A document by Wakefield, possibly from the Royal Free says that there is a link between Crohn’s disease and the measles vaccine. This given to prospective study subjects before being seen at the Royal Free. But no contamination of the study subjects again, right?

Child 12 was registered with Legal Aid before in August, two months before being seen by the Royal Free:

Q Also enclosed with that letter of 14 August 1996 were the legal aid forms. I think that is right. Did you fill in the legal aid forms in order for an application to be made for your child to be legally aided?
A Yes.

One issue that Mr. Wakefield has brought up in recent years is the concern over vaccines containing the Urabe strain of mumps. Mr. Wakefield has gone into detail about how he was informed by a “whistleblower” about how the government handled the licensure of those vaccines. Mr. Wakefield had those discussions with the whistleblower in 1999 but appears to have done little with the information until the past few years. Why? Perhaps this comment by his colleague Richard Barr will shed some light onto this: “Although Immravax and Pluservix were withdrawn on safety grounds, the particular problem they caused was fairly limited. ” It was the opinion of Mr. Barr at the time that the Urabe strain mumps concerns with some of the MMR vaccines was “fairly limited”. Mr. Barr and Mr. Wakefield, of course, had a different avenue to pursue: the measles/gut disease/autism hypothesis.

In Sept. 1996, Barr sent Mrs. 12 a newsletter:

Under the heading, “Pilot study”,

“If we can prove a clear link between the vaccines and autism/inflammatory bowel disease this will be exceedingly useful, not only for cases involving those conditions, but also for other types of damage such as epilepsy.

To obtain the evidence to do this, we will be running a pilot study. Around 10 children with symptoms which are closely linked to the vaccine will be extensively tested by a team of doctors headed by Dr Wakefield at the Royal Free Hospital in London. We will be selecting children to take part in the study from details and medical notes we already have. The investigations will involve a whole battery of tests to be carried out by a number of leading experts in their fields. We will of course be liaising closely with the families concerned and the doctors will be giving very full details of what will be involved”.

Need I point it out again? Before even arriving at the Royal Free, Mrs. 12 was informed about the need to provide a clear link between vaccines and autism/bowel disease.

Q We have heard from the Dawbarns newsletter that I read to you previously that as far as the solicitors were concerned there was a pilot study being arranged. Did you have any understanding or awareness whether your little boy was a part of that pilot study at all?
A He was referred to Dr Wakefield by my GP for investigations, which I understood to be research investigations, but that was the route he was referred.

She felt that her child was being referred for “research investigations”

Mr. Wakefield is keen to tell everyone that the referrals came through the GP’s. He doesn’t mention that he and Mr. Barr made sure ahead of time that they went through the GP’s:

“Dear Mrs [12]

Many thanks for your letter of 10 September 1996. I will contact some other parents in your area and if they agree then you can all swap names and addresses. It is interesting how isolated people feel (and sometimes are!).

I would like to see the records. These may well be helpful if we have any difficulties over legal aid. At the moment I am still waiting to hear from them.”

So that was the end of the correspondence, and I now want to ask you about the actual referral, which you have explained to us was through your GP to the Royal Free Hospital in respect of your boy. We have been through this already, but just to remind you, if you go back to the GP records, please, page 126, this is a letter that I asked you about when I first began to question you, Mrs 12, the letter from Dr Wakefield, and we see in that the suggestion that you in fact you should go to your GP for a referral. Did you do that?

Emphasis added.

On admission to the Royal Free:

Q “Soils – not had diarrhoea. Has variable abdominal pain”, and then I cannot read the rest of that sentence. Mr Miller is trying to assist me – “occurring every week”. Thank you. “Mother had not associated vaccination with his problems until met a parents support group”. Does that set out the problem as far as his gastrointestinal symptoms were concerned, I mean obviously in brief terms?
A Yes.

“Mother had not associated vaccination with his problems until met a parents support group”. Earlier in the transcript it is noted that this parent group included the mother of Child 6 and 7 and this is where Mrs. 12 was put in touch with Mr. Barr and Mr. Wakefield.

After her son was seen at the Royal Free, here’s the letter Mrs. 12 wrote. Note that she read the proposed “clinical and scientific study notes”. But this was just a routine referral, right?

“Dear Professor Walker-Smith,

I am writing following [Child 12’s] visit to the Royal Free Hospital last Friday 18 October 1996. My husband and I have thought long and hard about this situation since the appointment. We have also re-read Dr Wakefield’s proposed clinical and scientific study notes.

We do feel that [Child 12] does have a problem in that most children of his age do not soil themselves a number of times a day. As well as being pale in colour and foul smelling (as are his motions in general), this soiling is always very loose, which might explain why he is not always aware that he has done anything. Although I would not say it was diarrhoea exactly.

Obviously I do not wish to put my son through any procedures unnecessarily but there must be a reason why he has these problems. Also, as I mentioned to you at our meeting, [Child 12] is not growing or putting on weight like my other two children.

I keenly await the results of the blood tests and if you feel they warrant further investigations my husband and I are happy for him to be referred on to Dr Wakefield’s study project. As you pointed out, it might not help [Child 12] but if not hopefully it will be of benefit to others. There is also the chance that [Child 12] has a problem that can be detected and helped.

I do hope to hear from you in due course.”

In a letter to Mr. Wakefield she notes:

“Finally, I would like to say how nice it was to meet you at the JABS open meeting on 4 October in London. I found your short discourse both informative and interesting. I wish you all the best with your research.”

Yes, Wakefield was lecturing at JABS (an organization focused on vaccine injury) meetings. Mrs. 12 attended. This is Oct. 4, two weeks before her child was seen at the Royal Free.

Once again, we are in the merry-go-round. Mr. Wakefield only reported what the parents told him, except that here we have a clear example of a parent hearing from Mr. Wakefield on more than one occasion about what he was investigating.

The first visit to the Royal Free was not with Mr. Wakefield (Mr. Wakefield did not have clinical duties). Child 12 wasn’t even going to be referred to Mr. Wakefield at first:

Q So that was from your point of view, but you say in your letter to Dr Wakefield, Professor Walker-Smith’s main reasons for not referring [Child 12] on to Dr Wakefield was the absence of blood in the faeces and the lack of diarrhoea, you were saying that is what Professor Walker-Smith’s view was, is that correct?
A Yes.

But a blood test was “slightly abnormal” so they did make the referral.

“Dear [Mrs 12],

I do apologise for the delay in replying to your letter of 28 November. The slight abnormality that you referred to in your letter was that one of the markers of inflammation was just slightly above the normal range, it just means that we should go ahead. I understand that [Child 12] is coming in in the New Year to have a colonoscopy.”

A “slight abnormality” was enough to warrant a colonoscopy. Oddly enough, a later letter states that the blood tests were not abnormal.

The psychiatrist was not very clear on autism diagnosis:

Q If you to go page 18 in the medical records, we have a note dated 10 January, and in fact we have heard some evidence from Dr Berelowitz and he has given evidence in relation to all the children, including your son, and it was his evidence that this was his note, and we see at the bottom a diagnosis of “language delay ? [attention deficit disorder]” and then “? Asperger’s”: do you have any recollection of that?

The Royal Free didn’t think child 12 should have an MRI or a lumbar puncture.

Q If we go back to the Royal Free records – you can put FTP7 away, you will not need it again – at page 21 – it is on 6 January, so the day after the admission – at the bottom of the page it says, “[Ward round] Professor Walker-Smith” and it is a note signed by presumably a junior doctor, “colonoscopy” and then it gives, “prominent lymphoid follicles …” and “? some minor inflammatory changes” and then it says, “not to have MRI or L.P.” In other words, not to have an MRI scan and not to have a lumbar puncture. Then, Wednesday to have a barium meal. Were you aware at all of that note, Mrs 12? Were you aware at the time that that instruction had been given?
A No.

Emphasis added. But a colonoscopy and lumbar puncture were performed:

Q You say that you recall your son having a lumbar puncture and an MR scan; were you there for those?
A Yes.

Q You have obviously given consent for the MR but were you actually there when they were carried out?
A Yes.

Q Both of them?
A Yes.

Again, Mrs. 12 felt this was a research project:

Q You have told us that you thought that your son was part of a research investigation. Did you have any understanding as to which of those investigations, all of them or any of them, were part of the research investigations?
A As far as I understood, it was all part of the research into this possible link between the problems that [Child 12] had and the vaccine.

The tests apparently showed some immune activation

“Dear [Mr and Mrs 12],

I am writing to confirm the results from [Child 12]’s visit in the New Year. All were normal, including test for Fragile X, except the immune test. This shows evidence of persistent viral infection; i.e. [Child 12]’s immune system is activated in such a way that indicates it is trying to deal with some sort of ongoing viral infection. If you need to discuss these further please contact Dr Wakefield. I have passed on your query about gluten free diets to Dr Wakefield. I hope that [Child 12] is well and that his aching knees are settling”.

Then she gives some results at the bottom of the page. It shows,

“Full blood count and inflammatory markers – normal (i.e. no evidence of anaemia or inflammation”,

and various other negative tests.

Emphasis added. But above we read that the reason why Child 12 was referred for a colonoscopy was because a blood test indicated possible inflammation.

In June 1997, after the work at the Royal Free was finished, the attorney, Richard Barr, wrote to Mrs. 12:

“Thank you for your letters of 3 and 10 May 1997. I am sorry about the delay in coming back to you. I inevitably seem to be behind with my correspondence.

I haven’t heard anything more from the Vaccine damage Tribunal”.

Then he says,

“I haven’t had a copy of the Meridian TV item”,

so obviously you had made some reference to it, because he says,

“I would be very interested to see a copy if you can organise it some time.

We are all waiting for Andy Wakefield to deliver the goods and I really think that if he can provide the proof he thinks he can it is going to be much easier to win the cases.

I am interested in your comments about the rise in the incidence of mumps. What you say, of course, is absolutely correct.

I don’t think you have been updated on our fact sheet recently and in case it is of interest I enclose a further updated version. You will see that once again the section on autism has been extended. Don’t be deceived by the fact that it may not look quite as long as before. We have reduced the print size”.

Emphasis added.

After an extensive examination by the GMC’s attorneys, the defense was given an opportunity to cross exam:

THE CHAIRMAN: Mrs 12, as I indicated earlier, this is now the opportunity for representative counsel of the three doctors to cross-question you if they feel it appropriate. Are you happy to continue?
A Yes, that is fine.

THE CHAIRMAN: At any stage if you think that you need a little break, just give me a little hint and I am sure that the Panel will be quite sympathetic. Mr Coonan.

MR COONAN: Sir, I have no questions, thank you.

Mr. Coonan would be Mr. Wakefield’s attorney. He declined the opportunity to examine the one parent from the Lancet 12 who appeared at the GMC.

Mrs 12 was cross examined by Mr. Miller, attorney for Professor Walker-Smith.

Even as a summary this is long. But at least now people can easily check quotes in context.

Estimating the Prevalence of Autism Spectrum Conditions in Adults: Extending the 2007 Adult Psychiatric Morbidity Survey

1 Feb

You may recall that a couple of years ago a study came out looking at the prevalence of autism in adults in the United Kingdom. They found a prevalence of about 1%, the same as in children.

There’s now a follow up study. The press release is below. The study can be found here. I hope to have the time to go into this in more detail in the next couple of days.

University of Leicester researchers lead on new autism study published today
Britain’s first adult autism survey reveals previously ‘invisible’ group with autism

New research on autism in adults has shown that adults with a more severe learning disability have a greater likelihood of having autism.

This group, mostly living in private households, was previously ‘invisible’ in estimates of autism.

Dr Terry Brugha, Professor of Psychiatry at the University of Leicester, led research on behalf of the University for the report Estimating the Prevalence of Autism Spectrum Conditions in Adults: Extending the 2007 Adult Psychiatric Morbidity Survey, which has today been published by the NHS Information Centre.

The report involved a survey of adults from learning disability registers in Leicestershire, Lambeth and Sheffield between August 2010 and April 2011.

Today’s report presents findings from a new study based on a sample of people with learning disabilities living in private households and communal care establishments. The findings are combined with information from the Adult Psychiatric Morbidity Survey (APMS) 2007, previously published by the NHS Information Centre, which included research on autism also led by Dr Brugha.

Dr Brugha, also a consultant psychiatrist working in the NHS with the Leicestershire Partnership NHS Trust, said: “We were surprised by how many adults with moderate to profound learning disability had autism because previous estimates pointed to lower rates in this group. Because they form a very small part of the adult population, when we added these new findings to the rate we had previously found in adults living in private households, and able to take part in our national survey in 2007, the overall percentage of adults in England with autism did not increase significantly over our 2007 estimate of 1%.”

“Our finding that about 60% of men with profound learning disabilities and 43% of women with profound learning disabilities have autism has never been shown previously. It may also seem surprising how many live at home with parents or carers who provide 24 hour care and shoulder a considerable burden: 42% of men and 29% of women with severe learning disabilities living with family members and in other private households have autism. Taken together with the 2007 survey findings this means that most adults with autism live in private households, and before these two surveys they remained largely invisible”.

Dr Brugha added “This new information will be of particular importance for those who plan and provide services to support those with learning disabilities. In March 2010, the Government published a national strategy for autism and guidance for the condition, with the view to improving the quality of services provided to adults with autism in England. Such improvements can only be achieved if the number of people with recognised and unrecognised autism is quantified. The strategy gave special emphasis to the need to train staff who have responsibility for identifying people with autism and their care. It will be vital to repeat such studies in future years in order to make sure that the national strategy is working effectively.”

Sally-Ann Cooper, Professor of Learning Disabilities at the University of Glasgow, who also contributed to the latest study commented: “Until now routine statistics have not been gathered on the numbers of people with learning disabilities who also have autism leaving this as a hidden problem. Our study clearly shows that the more severe to profound an adult’s learning disability is, the more likely they will be found to have autism if actually assessed.”

Mother Jones: Rep. Dan Burton’s Legacy: Lots of Sick Kids

1 Feb

Dan Burton, representative to the U.S. House of Representatives from Indiana announced today he would not seek re-election this year. Mother Jones has an article to mark the end of Dan Burton’s career in congress: Rep. Dan Burton’s Legacy: Lots of Sick Kids. The link says a lot “rep-dan-burton-goodbye-and-good-riddance”.

Stephanie Mencimer of Mother Jones starts out:

So Rep. Dan Burton (R-Ind.) is finally retiring, after two decades in Congress. He’s got a notable record of craziness, having doggedly pursued President Bill Clinton during the Monica Lewinsky scandal while knowing full well he’d had an affair himself and even fathered a child out of wedlock. He famously claimed to have shot up a “head-like object” (likely a melon or a pumpkin) to try to re-create the alleged “murder” of former Clinton deputy White House counsel Vince Foster, who committed suicide. But Burton doesn’t get enough credit for what may be his lasting legacy: helping turn Americans away from life-saving childhood vaccines.

Representative Burton has an autistic grandchild. Mr. Burton is of the belief that vaccines were causal in that autism. If you’ve read David Kirby’s book, “Evidence of Harm, Mercury in Vaccines and the Autism Epidemic: A Medical” you know that Rep. Burton is a major figure in that narrative.

Rep Burton helped promote Andrew Wakefield’s ideas, including a hearing held in 2000. Mr. Wakefield’s testimony is not exactly what I would call accurate. As is now well known, Mr. Wakefield was financially supported by attorneys seeking to prove a link between the MMR vaccine and autism. When Rep. Burton asked him about financial support, here’s how Mr. Wakefield responded:

Mr. Burton. Who funded your study, Dr. Wakefield?
Dr. Wakefield. We did. We have a small charitable
contribution, but—-
Mr. Burton. A charitable organization did; I see.
Dr. Wakefield. We found it a little difficult to get
funding—-

Mr. Burton cut Mr. Wakefield off at this point, addressing another speaker at the hearing. “A charitable contribution” is a rather odd way to describe money from attorneys. Mr. Burton held at least six hearings on vaccines. That is not a problem. However, the evidence was going from weak to strongly against him over the years.

Mr. Burton has thankfully been more quiet on the issue in his recent years in office. Still, I’m with Mother Jones on this. Good Bye and Good Riddance.

Joint ASAN-Autism Society Statement on DSM 5

31 Jan

Below is a joint statement by the Autistic Self Advocacy Network and the Autism Society of America on the DSM-5.

Dear Friend,

As two national organizations committed to working to empower the autism and Autistic communities today and into the future, the Autism Society of America and the Autistic Self Advocacy Network issue the following joint statement regarding the definition of Autism Spectrum Disorder within the DSM-5:

The autism spectrum is broad and diverse, including individuals with a wide range of functional needs, strengths and challenges. The DSM-5’s criteria for the new, unified autism spectrum disorder diagnosis must be able to reflect that diversity and range of experience.

Over the course of the last 60 years, the definition of autism has evolved and expanded to reflect growing scientific and societal understanding of the condition. That expansion has resulted in improved societal understanding of the experiences of individuals on the autism spectrum and their family members. It has also led to the development of innovative service-provision, treatment and support strategies whose continued existence is imperative to improving the life experiences of individuals and families. As the DSM-5’s final release approaches and the autism and Autistic communities prepare for a unified diagnosis of ASD encompassing the broad range of different autism experiences, it is important for us to keep a few basic priorities in mind.

One of the key principles of the medical profession has always been, “First, do no harm.” As such, it is essential that the DSM-5’s criteria are structured in such a way as to ensure that those who have or would have qualified for a diagnosis under the DSM-IV maintain access to an ASD diagnosis. Contrary to assertions that ASD is over diagnosed, evidence suggests that the opposite is the case – namely, that racial and ethnic minorities, women and girls, adults and individuals from rural and low-income communities face challenges in accessing diagnosis, even where they clearly fit criteria under the DSM-IV. Furthermore, additional effort is needed to ensure that the criteria for ASD in the DSM-5 are culturally competent and accessible to under-represented groups. Addressing the needs of marginalized communities has been a consistent problem with the DSM-IV.

Individuals receive a diagnosis for a wide variety of reasons. Evidence from research and practice supports the idea that enhancing access to diagnosis can result in substantial improvements in quality of life and more competent forms of service-provision and mental health treatment. This is particularly true for individuals receiving diagnosis later in life, who may have managed to discover coping strategies and other adaptive mechanisms which serve to mask traits of ASD prior to a diagnosis. Frequently, individuals who are diagnosed in adolescence or adulthood report that receiving a diagnosis results in improvements in the provision of existing services and mental health treatment, a conceptual framework that helps explain past experiences, greater self-understanding and informal support as well as an awareness of additional, previously unknown service options.

Some have criticized the idea of maintaining the existing, broad autism spectrum, stating that doing so takes limited resources away from those most in need. We contend that this is a misleading argument – no publicly funded resource is accessible to autistic adults and children solely on the basis of a diagnosis. Furthermore, while the fact that an individual has a diagnosis of autism spectrum disorder does not in and of itself provide access to any type of service-provision or funding, a diagnosis can be a useful contributing factor in assisting those who meet other functional eligibility criteria in accessing necessary supports, reasonable accommodations and legal protections. As such, we encourage the DSM-5 Neurodevelopmental Disorders Working Group to interpret the definition of autism spectrum disorder broadly, so as to ensure that all of those who can benefit from an ASD diagnosis have the ability to do so.

The Autism Society and Autistic Self Advocacy Network encourage other organizations and groups to join with us in forming a national coalition aimed at working on issues related to definition of the autism spectrum within the DSM-5. Community engagement and representation within the DSM-5 process itself is a critical component of ensuring accurate, scientific and research-validated diagnostic criteria. Furthermore, our community must work both before and after the finalization of the DSM-5 to conduct effective outreach and training on how to appropriately identify and diagnose all those on the autism spectrum, regardless of age, background or status in other under-represented groups.

Sincerely,
Ari Ne’eman

Autistic Self Advocacy Network

Generation Rescue’s tax form 990 for 2010

31 Jan

Generation Rescue’s tax forms (form 990) for 2010 have been made publicly available.

2010 was the second highest year financially for Generation Rescue. Here are their yearly totals:

2006: $318,695
2007: $425,317
2008: $1,185,255
2009: $623,597
2010: $1,078,471

GENERATION RESCUE IS DEDICATED TO RECOVERY FOR CHILDREN WITH AUTISM SPECTRUM DISORDERS BY PROVIDING GUIDANCE AND SUPPORT FOR MEDICAL TREATMENT

The largest expense was for “research”: $307,439. The description is not very detailed:

GR CONTINUES ITS COMMITMENT TO DISCOVERING THE CAUSES OF AUTISM SPECTRUM DISORDERS AS A MEANS OF IMPROVING TREATMENTS AND QUALITY OF LIFE, WHILE WORKING TOWARDS A PREVENTION AND A CURE. ANGELS DONATE THEIR TIME TO ANSWER QUESTIONS, GIVE GUIDANCE AND PROVIDE RESOURCES FOR FAMIILIES STARTING OUT ON THEIR OWN.

More on this later.

Other expenses? Marketing and Awareness, for one: $135,128

MARKETING & AWARENESS
GR IS DEDICATED TO SPREADING AWARENESS AND INFORMATION ABOUT AUTISM TO THE POPULATION AT LARGE, TO ENSURE THE UNDERSTANDING AND SUPPORT FOR THE DISORDER. GR WORKS CLOSELY ON A GRASSROOTS AND NATIONAL LEVEL TO ENGAGE FAMILIES IN THE PROCESS.

Rescue Family Grant Program: $96, 431

GR’S RESCUE FAMILY GRANT PROGRAM PROVIDES AUTISM TREATMENT SUPPORT TO INDIVIDUALS AND FAMILIES AFFECTED BY AUTISM SPECTRUM DISORDERS. GR PROUDLY PROVIDES FAMILIES WITH THIS UNIQUE AUTISM TREATMENT PROGRAM, WHICH MAY NOT OTHERWISE BE COVERED BY SCHOOL DISTRICTS, COUNTY PROGRAMS, INSURANCE OR OTHER GRANT-GENERATING ENTITIES.

Other program services: $328,660.

You may recall that this year Generation Rescue teamed up with AutismOne to produce the AutismOne conference. They made the conference “free” to attendees (with a $25 fee). Generation Rescue put out $76,467 to support the conference. Someone is obviously paying (exhibitors? Speakers?), Generation Rescue made $38,883 on the conference. Compare this with their comedy event where they spent $98,422 to make $15,327. Autism One is a much better deal for them.

Remember those research expenses mentioned above? I assume that this charge is included there: “Strategic Autism Initiative” got $100,000 “for researching the causes of autism:”. What’s the Strategic Autism Initiative? Simply put: Andrew Wakefield. That’s the organization he created after leaving Thoughtful House. Been wondering how Andrew Wakefield is paying the bills since losing that job? Well this gives you a big clue.

(For comparison, their “Family Grant” program received less money: $93,122 for 111 recipients.)

Under compensated board members, officers, etc., they list:

Jenny McCarthy, President, Director (10 hours/week, no pay)
Jonathan B Handley, Director (10 hours/week, no pay)
Lisa Handley, Director (10 hours/week, no pay)
and
Candace MacDonald, Executive Director (40 hours/week, $128,613)

Total in salaries and other compensation $260,569. (in 2009, this was $364,686)

Generation Rescue’s mission statement for 2010?

GENERATION RESCUE (GR) IS DEDICATED TO RECOVERY FOR CHILDREN WITH AUTISM SPECTRUM DISORDERS BY PROVIDING GUIDANCE AND SUPPORT FOR MEDICAL TREATMENT TO DIRECTLY IMPROVE THE CHILD’S QUALITY OF LIFE FOR ALL FAMILIES IN NEED

This has been evolving.

2009:

GENERATION RESCUE,INC IS AN INTERNATIONAL MOVEMENT 0F SCIENTISTS AND PHYSICIANS RESEARCHING THE CAUSES AND TREATMENTS FOR AUTISM, ADHD, AND CHRONIC ILLNESS WHILE PARENT-VOLUNTEERS MENTOR THOUSAND OF FAMILIES IN RECOVERING THEIR CHILDREN

2008:

CONTINUING RESEARCH, EDUCATION AND DISSEMINATION OF INFORMATION TO THE GENERAL PUBLIC AND MEDICAL PROFESSIONAL RELATING TO MERCURY TOXICITY AND ITS EFFECT ON CHILD DEVELOPMENT

(Generation started out as a major proponent of the idea that autism was a misdiagnosis for mercury poisoning)

One might notice that the “research” budget is significantly higher than that allocated to Mr. Wakefield’s organization. They allocate $307,439 for research. Compare this to 2009, when their support of research appears to be a single entry of $30,000 given to the HEAL Foundation.

$100,000 is going to Mr. Wakefield. Where is the other $208,439 going? Generation Rescue at one point felt they could do a vaccinated/unvaccinated study for $809,721. At that time it was proposed as a 2 year study. Is it in the works?
