Autism and mental retardation – genetic overlap

30 May

Post taken from Medical News Today

Researchers working with Professor Gudrun Rappold, Director of the Department of Molecular Human Genetics at Heidelberg University Hospital, have discovered previously unknown mutations in autistic and mentally impaired patients in what is known as the SHANK2 gene, a gene that is partially responsible for linking nerve cells. However, a single gene mutation is not always enough to trigger the illness. In some cases, a certain threshold of mutation must be exceeded. The researchers conclude from their results that a correct inner structure of the nerve cell synapses is necessary to enable the normal development of language, social competence, and cognitive capacity. Essential for the success of the project were the studies by the Heidelberg research team with the doctoral student Simone Berkel and collaboration with a Canadian research team headed by Steve Scherer. The study has already been published online in the leading scientific journal Nature Genetics.

Autism is a congenital perception and information-processing disorder of the brain that is often associated with low intelligence, but also with above-average intelligence. The disease is characterized by limited social communication and stereotypical or ritualized behavior. Men are affected much more frequently than women. Autism and mental retardation can occur together but also independently of one another and are determined to a great extent by hereditary factors. Some of the responsible genes have already been identified but the precise genetic mechanisms have not yet been explained.

Genetic makeup of hundreds of patients analyzed

Professor Rappold and her team focused their studies on the SHANK2 gene, which encodes a structural protein at the nerve cell synapses. It is responsible for the mesh structure of the basic substance in the postsynapse. Only when the postsynapse is properly structured can nerve impulses be correctly transmitted. The researchers analyzed the genetic material of a total of 396 patients with autism and 184 patients with mental retardation. They found different mutations in their SHANK2 genes in the area of individual base pairs, but also variants in the number of gene copies. The mutations led to varying degrees of symptoms. None of the observed gene variants occurred in healthy control persons. “Apparently an intact postsynaptic structure is especially important for the development of cognitive functions, language, and social competence,” explained Professor Rappold.

Identical mutations as the cause of different diseases

Some of the genetic mutations identified were new occurrences of mutations that were not inherited from the parents, but some of the mutations were also found in one parent. Since there are also healthy carriers of gene variants, we must assume that a certain threshold of gene mutations must be exceeded for the disease to appear. “Moreover, the same mutation can be present in an autistic patient with normal intelligence and in a mentally impaired patient,” said Professor Rappold. There is some overlap in the clinical symptoms of mental retardation and autism, which can now be explained by a common genetic cause.

Polls show vaccine refusers are mainstream?

29 May

This is the claim put forth in a recent “vaccine choice” rally. You’ve probably already read about the rally in Kev’s piece The American Rally for Personal Rights – bit of a damp squib. In his piece on the rally, Is the anti-vaccine movement fizzling?, Orac has videos courtesy of Bruce Critelliplus.

The rally started out with (amongst other statement) a statement from the conference organizers pointing to a survey they commissioned:

“We are mainstream America! And there’s no denying it. We have some important and special news to announce that was shared earlier this week in a press conference. Three weeks ago the center for personal rights contracted with Harris Interactive to conduct a national survey, the first of its kind…..

And here are the results:

Today, the majority of American Parents believe that they should have the rights to decide which vaccines their children should receive without regard to mandates

Chicago AntiVax Rally May 26 2010-Part 1 from Bruce Critelli on Vimeo.

If you’ve read this blog much before, you probably know I like to look at the numbers. So I checked the poll.

Here’s the first question:

All children should receive 69 doses of 16 vaccines before age 18, as recommended by the federal government.

Wow. All children? The Federal government does not recommend that all children get vaccines, in any number. The federal government acknowledges that some children are unable to be vaccinated due to medical conditions.

So, I would have disagreed with question one. Strongly. Does that mean that I agree with the center for personal choice? Hardly.

How many people did agree with question 1? 42%. Another 39% were neutral. I put it that the majority of people polled (and whoever wrote that question) do not understand the vaccine program.

Kind of makes it hard to take the rest of the poll seriously.

But, I like to look at trends. One trend I keep being told is valid is that vaccine refusers tend to be more educated and more well off financially. Basically, smart successful people tend to question vaccines, with the implication that this means the idea has merit.

The poll doesn’t bear this out.

Take question 2, the Government Mandate question quoted in the rally:

“Parents should have the right to decide which vaccines their children receive without government mandates.”

Parents with a high school education or less were in favor 51% of the time

Parents with a college education were in favor 57% of the time

Parents with grad school education? 48% of the time. Still high, but isn’t that interesting. Grad school educated parents were about 10 points less favorable to the idea than college educated parents.

How about income levels?

Parents with $75K annual income were in favor 48% of the time. Still high, but isn’t that interesting. High income parents were about 10 points less favorable to the idea than middle class families.

The income trend–where the high income parents were much less favorable than the middle income families–was the case for 4 of 5 questions:

Parents should have the right to decide which vaccines their children receive without government mandates.

I am concerned about serious adverse effects of vaccines.

The government should fund an independent scientific study of fully vaccinated vs. unvaccinated individuals to assess long-term health outcomes.

I am concerned that the pharmaceutical industry has undue influence over government vaccine mandates.

Frankly, I’d probably be counted as supporting the ideas of the self-styled vaccine choice movement based on careful wording of surveys. Doesn’t mean I actually support those organizations.

As an aside, the effort to rebuild Dr. Wakefield’s image is on. It’s just really weak. Dan Olmsted blogged about it at the Age of Autism blog. It is a rather odd piece. First, Dan Olmsted, regular at the Autism One conference (this rally was basically a satellite to that conference), didn’t attend the rally. Nor did any of the principle AoA bloggers. Mr. Olmsted finishes his piece with a statement about how autism was invented in America with thimerosal….How that supposedly supports Mr. Wakefield and his MMR hypothesis, I am unable to ascertain.

Mr. Wakefield’s book came out this week. You can read a good review of it here, Andrew Wakefield Fights Back, and save yourself the time and money of buying the book. Mr. Wakefield’s supporters have targeted Amazon.com to boost the ratings of the book, pushing it to something under 20 in the new books bestsellers list. At the same time, Barns and Noble had the book at about 28,000. In other words, don’t expect it to be on any real best seller lists soon. They are just manipulating a rather useless number.

Age of Autism called for a rally to support Mr. Wakefield following his appearance on the Today Show. There is no followup, no pictures and the post calling for the rally is rather uncluttered by comments from people claiming to have attended. Not even a comment from David Kirby, a short subway ride away. I really wish I had been there with a camera to see if there was any turnout at all.

On short notice, skeptics were able to rally more people to attend the “vaccination choice” rally in Chicago.

Yes, a fair fraction of the roughly 200 people who attended the rally were there as a protest. The rally, timed to coincide with the AutismOne conference, pulled only a small fraction of the AutOne attendees.

Are these groups “mainstream”? Do they represent the real thoughts of the people? I rather think not.

There’s been a bit of a blogstorm this week on Andrew Wakefield. I’m sure he will pop up from time to time in the future, but, let’s face it: He’s old news. He’s been telling everyone who will listen that “he’s not going away”. Doesn’t mean he’s still relevant.

Social influence and the autism epidemic

28 May

Prof. Peter Bearman at the University of Columbia has spent considerable effort studying the autism data from the California Department of Developmental Services.

I wrote about Prof. Bearman’s paper Social influence and the autism epidemic before. It just popped up in pubmed.

When I checked the website for the center where Prof. Bearman’s team works, I found the press release from the paper:

Study: “Social influence” playing role in increased autism diagnoses

Social influence plays a substantial role in recent increases in autism diagnoses, according to a study in the March, 2010 issue of the American Journal of Sociology.

The study, by researchers from the Institute for Social and Economic Research at Columbia University, found that children living near a child who has been previously diagnosed with the disorder are far more likely to be diagnosed themselves in the following year. The proximity effect is not due to environmental factors or contagious agents, the study found. Rather, it is due mainly to parents learning about autism from other parents who have a child diagnosed with autism.

“We show that the likelihood of getting an autism diagnosis is clearly associated with person-to-person transmission of information,” said Peter Bearman, a sociologist who authored the study along with Ka-Yuet Liu and Marissa King. “Parents learn about autism and its symptoms; learn about doctors who are able to diagnose it; and learn how to navigate the process of obtaining a diagnosis and services from parents who have already been through the process with their own child.”

The researchers stress that the results do not mean that autism is not real or that it is overdiagnosed. “Our study doesn’t address the underlying cause of autism,” Dr. Bearman said. “We are describing the mechanism by which the number of diagnoses is increasing. It could be that the real incidence of the disorder is only now being uncovered. I think that is a reasonable message from this paper.”

In California, where this study was conducted, the number of autism cases handled by the California Department of Developmental Services increased 636 percent between 1987 and 2003.

The Columbia University team looked at data on over 300,000 children born between 1997 and 2003 throughout California. The team found that children who live within 250 meters of a child with autism have a 42 percent higher chance of being diagnosed with the disorder in the following year compared with children who do not live near a child with autism. Children who lived between 250 meters and 500 meters from a child with autism were 22 percent more likely to be diagnosed. The chance of being diagnosed decreases significantly the farther children live from another child with autism.

The study used several tests to determine whether these results could indeed be explained by a social influence effect, or if environmental toxicants or a virus are to blame. For example, the researchers looked at children who live close to each other, but on opposite sides of school district boundaries. These children are likely exposed to the same environmental conditions, but their parents likely belong to different social networks. The research shows that the proximity effect only exists when parents reside in the same school district. Children who live equally close to a child with autism but in another school district were no more likely to be diagnosed with the disorder than children who do not have a neighbor with autism.

The results also showed the proximity effect to be strongest among children on the milder side of the autism spectrum. That is also consistent with a social influence explanation, Dr. Bearman says. “Parents of severely disabled kids are more likely to recognize the disorder without needing input from social contacts, so we would expect to see a weaker social influence effect there, and that’s exactly what we found.”

The Strength of Social Influence

The data set used in the study allowed the researchers to judge just how strong the influence effect is compared to other factors that may be driving the epidemic. For example, previous studies have found a link between autism and parents’ ages. Parents today are having children later in life, and that could be causing autism cases to increase. Other studies have found that parents’ education plays a role as well. Better educated parents may be more likely to obtain a diagnosis for their children.

The Columbia team found that each of these factors plays a role in the epidemic, but the social influence phenomenon was the strongest. The researchers estimate that the proximity effect explains about 16 percent of the recent increases in autism diagnoses. Put another way, if no child lived within 500 meters of a child with autism, there would be a 16 percent reduction in autism diagnoses. That effect was stronger than the other factors tested. For example, the mother’s age explained about 11 percent of the increase. The mother’s education accounted for 9 percent.

The study was funded by the NIH Pioneer award for innovative health research.

What caught my eye was that last paragraph, where they note that 16% of the increase can be accounted for from this social influence phenomenon, but also that 11% was due to increased maternal age and maternal education accounts for another 9%.

This is in addition to diagnostic substitution, which accounts for about 25% of the increase in the CDDS client caseload.

One of the footnotes in the Social Influence paper also caught my eye:

The strong positive association of autism (during the period of increasing prevalence, 1992–2000) with socioeconomic status (King and Bearman 2009b), coupled with the increasingly negative socioeconomic status gradient for MR (arising from differential abortion rates for fetuses identified as chromosomally damaged through amniocentesis), has led to a relative stigma reversal and a consequent decline in the rate of MR diagnoses.

King and BEarman, 2009b is a “working paper” at Columbia University (“The Increased Prevalence of Autism.” Working paper. Columbia University, Paul F. Lazarsfeld Center for the Social Sciences.)

One feature that is very interesting in the paper is the how the level of “functioning” of the child relates to the social influence effect. The basic result of the paper is that when a family lives near another family with an autistic child, they are more likely to obtain CDDS services under the autism label. That effect is stronger for “high functioning” autism. To me, at least, this seemed counter intuitive. Here is a graph from the paper showing that the social influence effect means that a child with “high-functioning” autism is about 40% more likely to be registered with the CDDS if he/she lives close to a family with an autistic child.

The trend with proximity is very clear, as shown in the figure below. The probability of a child be registered with the CDDS with an autism label drops off very smoothly and clearly with distance to a family whose child was recently diagnosed. This is not seen for mental retardation.

As the authors point out:

Compared with children who are 501 meters–1 kilometer away from their nearest neighbor with autism, those in close proximity (1–250 meters) to a child with autism have a 42% higher chance of being diagnosed with autism in the subsequent year. Proximity of 201–500 meters increases the chance by 22%. In contrast, being farther away from a child with autism reduces the chance of a diagnosis.

I know this is a repeat in many respects. But I also have found this work to be very interesting and thought it worthwhile to bring up these points I didn’t discuss before.

Death better than autism says Andrew Wakefield

28 May

When I first got involved in this, 15 years ago, I got a call from a parent in the North of England who said ‘Dr Wakefield please do not judge me harshly but when I die I’m taking my child with me, because I’m the only one who loves him’ and I didn’t judge that mother at all. In fact I was moved by the love of a mother must have for her child to take his life rather than him fall upon a society that really didn’t give a damn.

http://vimeo.com/12079650 from 2:30 to 3:25.

Those who are regular readers of LBRB may guess how I felt upon hearing such words coming from a man who swore as a doctor to do no harm. If nothing else, they confirm exactly the type of human being Andrew Wakefield is. I also note he waited until _after_ the GMC hearings before expressing such an extreme viewpoint.

I believe that death is not better than autism. Part of the reason LB/RB exists and continues to exist is to counter the idea that autistic people are second hand citizens who can be done away with because of false ideas that they are ‘inconvenient’. There are no reasons based in any morality that it is ever OK to kill another human being. The fact that the other human being might be autistic is irrelevant.

I was already disgusted and appalled at the money grabbing callousness of Andrew Wakefield. Now I find myself more than anything, relieved that the GMC acted as they did and that he has no more access to children in the UK.

The American Rally for Personal Rights – bit of a damp squib

27 May

Yesterday was the American Rally for Personal Rights (an anti-vaccine rally) held between 3pm and 5pm in a park in Chicago, US. In attendance was ex-doctor Andrew Wakefield in whose honour the rally was held.

Hoping for thousands, the organisers got what looks like a hundred or so (click for full size).

including one young man (A certain J. Crosby, Age of Autism Editor) who carried the sign ‘Autistics for Wakefield’

I’m not entirely certain who the autistics were. I mean I see Jake but no one else. Also in attendance were Wade Rankin, Erik Nanstiel, Boyd Haley, Bob Krakow and Jim Moody and for ‘name’ anti-vaxxers that was it. No Jenny McCarthy, No Jim Carrey, No Generation Rescue, No Age of Autism bigwigs (aside from young master Crosby of course).

Of course for bloggers such as I, this is a tad disappointing. There’s not really a lot to talk about when nothing much happens, nobody of any consequence shows up and the whole thing resembles a rain-soaked firecracker.

On the bright side, there were The Refusers who I’m pretty sure would’ve been good for a very hearty laugh. Aside from that – nothing really to tell. The sun was out, some anti-vaxxers waved a few signs around and the world collectively yawned.

See ANB’s take on it, he actually attended the rally himself.

Andrew Wakefield/Today Show interview transcript

27 May

Reformatted and tidied up from a commenter on a Yahoo Group

INTRO

MATT LAUER: [But]…in the years following his publication in The Lancet.no large scale study could reproduce exactly what Dr. Wakefield’s small study found. Dr. Wakefield is here for an exclusive interview. Doctor, good morning.

WAKEFIELD: Good morning Matt.

MATT LAUER: It may sound like a strange way to start the interview but…do I still refer to you as Doctor?

WAKEFIELD: Yes, they can’t take away the fact that I have a medical degree.

MATT LAUER: You were not surprised by this action … the stripping of your medical license. Why?

WAKEFIELD: Not at all. It was determined from the very beginning I believe, the pressure the government brought on the GMC .. to find this ruling.

MATT LAUER: You don’t think this was an impartial panel?

WAKEFIELD: I think that the panel .. whether they believe they were influenced or not .. were certainly of this opinion .. when I read their decision which came out in February .. this decision had been made from the outset.

MATT LAUER: Doctor is this the final blow to your credibility? Doctor, I mean if you look at the studies that have been conducted since your research wved your theories. The fact that The Lancet has since said, “If we knew then what we know now, we wouldn’t have published the study in the first place”. You lost your job down in Texas and now your medical license. Is that it?

WAKEFIELD: The findings we made originally have been replicated in five different countries of the world. So, the bowel disease in these children exists. This is a little bump on the road .. and .. that’s how it should be perceived. It’s a bump on a very bumpy road .. but .. it’s a bump. What it does not detract from is the fact there are millions of children out their suffering .. and .. the fact that vaccines can cause autism. That’s a fact that’s accepted by the American government … because they have been settling cases of vaccine induced autism since 1991.

MATT LAUER: You say to me the findings have been replicated. I have seen studies, several major studies. Your study involved twelve children … I’ve seen studies that involved hundreds of thousands of children that do not replicate your findings. And, so, today .. will you sit across from me and tell me you still believe there is a possible link between tha particular vaccine .. the MMR vaccine .. and .. autism in children?

WAKEFIELD: Not only do I think it .. but .. the American government has conceded that it exists. A causal relationship between vaccines and autism exists .. and .. they have actually been secretly settling cases as early as 1991. Out of court as well.

MATT LAUER: As you know, we have talked to people since we had a chance to meet .. when you were kind enough to sit down for that exclusive interview with us .. and .. people in our government have said “NO! NO! We no longer believe this. We went out and checked out the possibilities and we no longer believe this to be true.” And .. every doctor I’ve spoken to says “It’s dangerous … it’s dangerous to even keep talking about it because .. every time you talk about it .. parents stop vaccinating their children .. and .. some children are dying from preventable diseases”.

WAKEFIELD: Matt, you are missing the point. The point is .. despite denying it .. in the public relations campaign they waged against me and against the parents .. they are conceding these cases in vaccine court.

MATT LAUER: What’s your next step .. real quickly?

WAKEFIELD: My next step is to continue this work till it’s natural conclusion. These parents are no going away, the children aren’t going away ..and .. I most certainly am not going away.

MATT LAUER: Dr. Andrew Wakefield, thank you for joining us. I appreciate your time….

Anne Dachel, Age of Autism Editor, makes remarkable claim

27 May

I was browsing the comments section of a seemingly innocuous story about autism – that early intervention might not be the universal panacea once thought – when I came across a comment from Anne Dachel, one of the leading ‘thinkers’ and editors behind the online anti-vaccine blog Age of Autism.

…I think a disorder that was unheard of 25 years ago…

I had to read it a couple of times to make sure I was seeing it right – I was – Anne Dachel believes autism was unheard of prior to 1985.

To say this is a remarkable claim is being overly fair to Dachel. Its one of those claims that is regularly made by the Age of Autism team that leaves one’s jaw on one’s chest with the sheer audacity of either its boldness or stupidity. It reminds one of John Best’s claim that autism was unheard of in China prior to 1999. Another rampant piece of stupidity.

As previously noted, Dachel writes for Age of Autism. I’ll leave you to form your own conclusions as to the accuracy of their blogging based on their Editors own bizarre beliefs about autism.

Study Finds Supplements Contain Contaminants

27 May

A story in the New York Times by Gardiner Harris discusses the results of a Congressional investigation on dietary supplements. Many were found to be contaminated with heavy metals and/or pesticides:

Nearly all of the herbal dietary supplements tested in a Congressional investigation contained trace amounts of lead and other contaminants, and some supplement sellers made illegal claims that their products can cure cancer and other diseases, investigators found.

The levels of heavy metals — including mercury, cadmium and arsenic — did not exceed thresholds considered dangerous, the investigators found. However, 16 of the 40 supplements tested contained pesticide residues that appeared to exceed legal limits, the investigators found. In some cases, the government has not set allowable levels of these pesticides because of a paucity of scientific research.

You can read the actual report in summary, highlights and full report.

The report focused on herbal supplements like Ginko and St. John’s Wort. The levels were low as noted:

GAO also found trace amounts of at least one potentially hazardous contaminant in 37 of the 40 herbal dietary supplement products tested, though none in amounts considered to pose an acute toxicity hazard. All 37 supplements tested positive for trace amounts of lead; of those, 32 also contained mercury, 28 cadmium, 21 arsenic, and 18 residues from at least one pesticide. The levels of heavy metals found do not exceed any FDA or Environmental Protection Agency (EPA) regulations governing dietary supplements or their raw ingredients, and FDA and EPA officials did not express concern regarding any immediate negative health consequences from consuming these 40 supplements.

Earlier this year, Kirkman Labs (who markets their supplements towards the autism parent community) was found to have a number of supplements contaminated with antimony.

A representative for the Council for Responsible Nurtirion downplayed the contamination issues:

Steve Mister, president of the Council for Responsible Nutrition, a trade association representing the dietary supplement industry, said it was not surprising that herbal supplements contained trace amounts of heavy metals, because these are routinely found in soil and plants. “I don’t think this should be of concern to consumers,” Mr. Mister said.

Andrew Wakefield sets out his talking points in a new book

27 May

Only a few years ago it seemed you couldn’t go into an online discussion without hearing David Kirby’s talking points from his book Evidence of Harm. I recall hearing over and over about pink’s disease, Minimata disease and many more “facts” that had really nothing to do with autism.

Now it seems to be Dr. Wakefield’s chance to shape (again) the discussion. His book “Callous Disregard” is sort of published (published but not generally available from what I can see). Luckily, a blogger for Examiner.com seems to have a copy and he lays out Mr. Wakefield’s responses to the ethics lapses which cost him his license in the UK. The talking points seem mostly to be about Mr. Wakefield, rather than about autism, but let’s go through them and see how they stand up to scrutiny, shall we?

Keep one thing in mind, Mr. Wakefield’s arguments seem to this observer to be of the type to mire people in details and confuse the issues with sidetracks.

Regarding financial conflicts of interest, Wakefield says that the funds for the Lancet 12 study came from the National Health Service. According to Wakefield, the money he received from lawyer Richard Barr was for a separate study looking for measles in the intestine of affected children. Wakefield states that the parents of the 12 children in the Lancet study came to him before he was hired as an expert on MMR litigation.

Wakefield writes that he was not required in 1997 to publish in the Lancet article his role of being an expert on MMR litigation but he did notify appropriate officials: “Long before publication ? details of my involvement as an expert in the litigation had been provided to my senior coauthors, the dean of the medical school, and the editor of The Lancet.”

As with much of Mr. Wakefield’s explanation, Brian Deer has responded to this one. But, let’s take a different look:

Andrew Wakefield was the key person in the Royal Free Hospital’s press conference on his paper in the Lancet. At that time, Mr. Wakefield was in the employ of lawyers seeking to litigate MMR injury cases. At that time he called into question the safety of the MMR vaccine.

INTERVIEWER: But if you say there’s at least a question mark over it now, should the vaccine continue to be administered while you’re investigating?

DR ANDREW WAKEFIELD: I think if you asked members of the team that have investigated this they would give you different answers. And I have to say that there is sufficient anxiety in my own mind of the safety, the long term safety of the polyvalent, that is the MMR vaccination in combination, that I think that it should be suspended in favour of the single vaccines, that is continued use of the individual measles, mumps and rubella components.

What do you think? Should a person working as a paid expert in MMR litigation announce this in a press conference where he calls for the suspension of the MMR vaccine? I would suggest that pretty much anyone who looked at this would say, “Yes, he should have made his conflict of interest public”.

Mr. Frandsen continues:

In a letter to pediatric gastroenterologist John Walker-Smith in February 1997, Wakefield explained his reasons for acting as an expert:

“Vaccination is designed to protect the majority, and it does so at the expense of a minority of individuals who suffer adverse consequenses…If this disease is caused by the MMR vaccination, then these childen (sic) are the few unfortunates that have been sacrificed to protect the majority of the children in this country. If that is the case, our society has an absolute obligation to compensate and care for those who have been damaged by the vaccine for the greater good.”

Which is irrelevant to the question of whether Mr. Wakefield’s actions were ethical. Really, how does the above apply to, say, whether Mr Wakefield had a conflict of interest or performed procedures without ethical approval? It doesn’t.

Wakefield was accused of conducting unnecessary and invasive medical procedures such as lumbar puncture on children with autism. Wakefield states that the history of developmental regression justified lumbar punctures. Later it would be discovered that neuro-inflammation in children in autism showed abnormal cytokine levels in cerebral spinal fluid. In addition, Swedish autism expert Christopher Gillberg advocates lumbar punctures to exclude encephalitis, and the procedure is conducted on children with autism in the U.S.

First, many lumbar punctures were performed before ethical approval was granted. Second, and more importantly, many of the lumbar punctures were found to be unnecessary. Here is but one comment from the GMC finding on Mr. Wakefield:

The Panel has taken into account that there is no evidence in Child 3’s clinical notes to indicate that a lumbar puncture was required. Professor Rutter and Dr Thomas, experts on both sides, considered that such a test was not clinically indicated.

Note–experts from both sides considered that the test was not clinically indicated. So, even Mr. Wakefield’s expert agreed that there was no reason to do a lumbar puncture on this child.

Anecdote here–I don’t think I have ever run into a parent who had their autistic child undergo a lumbar puncture. Autism is not a general indication for lumbar puncture. How many times have you read in the comments on, say, the Age of Autism blog, “When we got our lumbar puncture…”

Mr. Frandsen continues:

Regarding “data fixing” alleged by a British journalist, Wakefield said there were no allegations by the GMC that he manipulated data: “In the hands of someone determined to discredit the work, discrepancies between the routine clinical report (which may have come, for example, from a pathologist with an interest in brain disease or gynecological pathology) and the standardized expert analysis were falsely reported in the national media as ‘fixing’ of the data.”

One good reason why “data fixing” was not a charge by the GMC is very simple–the information on “data fixing” came out from the GMC hearings. The charges were, not surprisingly, made before the hearings.

I would like to see what an investigation into the question of data fixing would conclude.

On the decision by the Lancet’s editors to retract the article because the 12 patients in the study were not “consecutively referred,” Wakefield responds, “This is bizarre, since it is factually entirely correct – these were the first 12 children to be referred to the care of Walker-Smith with a regressive developmental disorder and intestinal symptoms.” Wakefield writes in the book that he indeed did have ethics committee approval to conduct the research elements of the Lancet study.

Let’s look at this in pieces–Mr. Wakefield is redefining “consecutively referred” to suit his needs. How did the GMC interpret “consecutively referred”?

The Panel is satisfied that a general reader would interpret the wording in 30a to mean that children were referred to the gastroenterology department with gastrointestinal symptoms and that the investigators had played no active part in that referral.

But, Mr. Wakefield’s team did play an active part in the recruitment of at least some of the children involved in the study. Not all of the children were referred for GI complaints.

Or, to put it quite simply: the statement “consecutively referred” was supposed to tell us all that there was no bias in how the patients came to be in the care of the Royal Free. But the truth was that there were huge biases involved.

Here is what the GMC had to say on this question:

Having regard to its findings in relation to Child 1, 9, 5 and 10, namely that these children were admitted to undergo a programme of investigations for research purposes, and that they all lacked a history of gastrointestinal symptoms, the Panel is satisfied that these referrals did not constitute routine referrals to the gastroenterology department.

Now let’s address the last sentence in that section above “Wakefield writes in the book that he indeed did have ethics committee approval to conduct the research elements of the Lancet study.”

This is one of those things where Mr. Wakefield and his supporters try to bury people in the details to create doubt. He claims that there was an approval in place, for project 162-95. The GMC rejected that idea:

The Panel has heard that ethical approval had been sought and granted for other trials and it has been specifically suggested that Project 172-96 was never undertaken and that in fact, the Lancet 12 children’s investigations were clinically indicated and the research parts of those clinically justified investigations were covered by Project 162-95. In the light of all the available evidence, the Panel rejected this proposition.

Why would they reject the idea? Project 162-95 allowed Prof. Walker-Smith to take two extra biopsies for research purposes when he did colonoscopies on patients.

Rather than get mired in the details ask a simple question: How does that allow the team to, say, perform lumbar punctures? Simple answer, it doesn’t.

Wakefield also cites conflict of interest among his critics. Professor Michael Rutter of the Institute of Psychiatry, a witness for the prosecution in the GMC case, had been a paid expert by vaccine manufacturers and the U.S. government. Dean Arie Zuckerman of the Royal Free Hospital wrote to the British Medical Association in October 1996 worried that Wakefield’s study could lead to a case against the government.

Assume it is all true. Does it change anything about Mr. Wakefield’s ethical lapses? It is the researcher version of “But mom, the other kids shoplift too”.

Wakefield answers the charges that it was unethical to take blood samples from children at his own child’s birthday party in 1999 to compare with samples of children with autism. “The blood was taken by a suitably qualified medical practitioner with standard aseptic precautions. Children were rewarded with the equivalent of just over $7. The entire procedure passed off without mishap or complaint. This process did not have the approval of an EC (Ethics Committee), which I now accept was naïve, but it was most certainly not unethical,” Wakefield writes.

Let’s boil this down to the basics: Mr. Wakefield made children into study subjects without first obtaining ethics approval.

That is unethical. By definition. Mr. Wakefield is not in a position to say “it wasn’t that bad an ethical breach” or “it happened safely”. What he really can’t say is “well, it would have been approved if I had asked”. None of those excuses work at all. His actions were unethical.

As if to make that point, the article goes on:

Wakefield compares that to a measles and rubella (MR) campaign the UK administered to approximately 8 million school children in November 1994: “In contrast, the MR campaign had multiple ethical failings on many levels, but the most staggering omission of all seems to me to have been the failure to alert parents to the known threat of severe adverse reactions – to deny them the fundamental right of informed consent in making a decision about their child. It puts the birthday party into the shade and rather makes a mockery of the post-GMC headlines about my callous disregard.”

Basically, Mr. Wakefield is saying, “other people were more unethical, so you should ignore my small ethical breaches”.

The birthday party story just fills in the narrative that Mr. Wakefield had a “callous disregard” for obtaining ethics approvals. Whether it was for very serious procedures on disabled children (lumbar punctures) or smaller actions like blood draws from non-autistic young children, he exhibited a pattern of unethical behavior.

“My experience serves as a cynical example to discourage others,” writes Wakefield. “As a consequence, many physicians in the United Kingdom and United States will not risk providing the care that is due to these children.”

This is a diversionary tactic. He’s using disabled children as a shield. Doctors in the US and the UK–and the world over–should not provide “care” that is not clinically required and potentially risky in order to obtain research results to support litigation. And that is where Mr. Wakefield failed.

In his piece, Mike Frandsen goes on with another talking point by Dr. Wakefield: that the US Government has acknowledged that vaccines cause autism. He cites the Hannah Poling case, the Bailey Banks case and the Hiatt case.

Again, let’s avoid getting bogged down in the details of those case and ask the simple question: did any of them involve Mr. Wakefield’s hypothesis of persistent measles in the gut? Answer, no.

This is another diversion.

Mr. Frandsen goes on to state:

Injury claims filed with the National Vaccine Injury Compensation Program since 1989 total 12,356. Claims involving deaths from vaccines number 1,035 in the same time period. According the VICP website, 52 cases have been filed for deaths since 1989 involving MMR and 19 cases filed for deaths involving the measles vaccine. Of those cases alleging injury or death due to vaccines, the U.S. government has compensated 2,440 awards totaling more than 1.8 billion dollars, though none of the awards have been compensated specifically for autism, according to the government’s statistics.

Again, what does any of this have to do with Mr. Wakefield’s research? Nothing. If they had a single case that was on point, they’d use it.

More to the point, what does this have to do with whether Mr. Wakefield’s research was performed *ethically*? Answer: nothing.

That’s always a good question to ask as Mr. Wakefield attempts to reinvent his image: does his excuse really address the issues? Mostly, do they address the issues of whether he acted ethically in his research activities? The answer is a very clear “no”.

Do you think vaccines are related to autism?

24 May

Do you think vaccines are related to autism? That is the question that the Today Show has posed in an online poll.

The Age of Autism has called for a Poll Mob via Twitter:

http://bit.ly/a69a4X Take NBC poll, do you think there is autism vaccine link. So far 54% yes.

Well, in the two hours since they posted that, the “yes” answer has gone from 54% to 44%.

If you have the time and the inclination, let them know what you think. Do you think vaccines are related to autism.
