Penn Point: Anti Vaccination is Bull Andrew Wakefield and Jenny McCarthy

21 Jun

Penn of Penn and Teller has an internet TV show called Penn Point. In the recent installment Penn discusses Andrew Wakefield and Jenny McCarthy. I hesitated posting this as Penn is proficient, fluent even in, in profanity. So be warned. I also hesitate because I don’t want to get into the “My celebrity is better than your celebrity” arguments. I’m not putting this out because Penn is an expert. No, he’s no expert. He’s a celebrity. A celebrity who wants to champion the little guy being trampled by “the Man”. In this case, he says, “The man is right”, Mr. Wakefield and Ms. McCarthy are wrong.

Penn Point: Anti Vaccination is Bull*** Andrew Wakefield and Jenny McCarthy

Penn and Teller have been working for some time on an episode of their Cable TV program “Bullshit” which takes on the anti-vaccine movement. They fought with Showtime to do anti-aniti-vaccination. Yes, they had to fight to do this show. The anti-vaccine groups have had the sympathy of the media for some time. But, times are changing. Now, even a show like Bullshit, which takes on “The Man” (the establishment), is willing to take a critical look at people like Andrew Wakefield, Jenny McCarthy and Oprah.

The short bit in Penn Point notes that at the time they did the show Mr. Wakefield was not yet struck off so they were more careful with him. Keep that in mind when the episode airs. They went easy on him. Also of note, Penn references the Bad Astronomy blog. Bad Astronomy mentions this Penn Point in Penn’s – and the syringe’s – point.

The Penn Point show is here:

I could write the responses to that episode now, complete with complaints about how Mr. Wakefield’s study isn’t completely discredited ( [a] “it isn’t a study, it is a case series, [b] it has been replicated in five countries, [c] how dare he claim that Jenny McCarthy isn’t helping people–look at her books and talks….etc.).

But, again, I’ll stress: I’m blogging this not to say Penn is correct or to use his words as some sort of expert in the discussion. No. To me this is about the fact that the media viewpoint has shifted away from sympathy and false balance for the vaccines-caused-an-autism-epidemic groups. Consider the recent episode of Frontline and the recent episode of Dateline which both covered the vaccine-autism discussion and (especially in the case of Dateline) Mr. Wakefield. Both were very critical of Mr. Wakefield, and that was before Mr. Wakefield was struck off the General Medical Council register.

The groups focusing on vaccine causation have relied upon a sympathetic media for some time. Without it, they would have had a much harder time putting out a message which their media representative claims “…has severely eroded confidence in the cornerstone of health care: THE CHILDHOOD VACCINE PROGRAM.”

That said, I was actually looking forward to winding down discussion of Mr. Wakefield. He’s moved from front-page news in reputable media sources to a late night guest on AM radio shows which concentrate on UFO’s.

But, as long as I am on the subject of Mr. Wakefield (regular guy), let me make a few recent observations:

Mr. Wakefield recently gave a talk in London. Or, as it was billed, people were able to have an “audience” with Andrew Wakefield. The lecture presented his current stump speech and was followed by a book signing. About 40 people attended. The live feed of the event was to be carried “pay per view”, with a fee of about US$70. The organizers abandoned that idea and put it out free. Even with that they were only able to get about 150 online viewers, which included many skeptics (including members of the Bad Science forum).

A good example of the sort of information Mr. Wakefield’s speeches include is a shifting of blame for the drop in immunizations in the UK to the government. It was there decision, he asserts, to remove the single vaccines which led to the outbreaks. As noted in the Telegraph recently, the UK has never had a single mumps vaccine:

‘Rubbish,’ says Salisbury. ‘There was no mumps vaccination licensed for routine use – certainly none available in the UK. We had never used a single mumps vaccination.

We could go on and on. Mr. Wakefield, who has supposedly thoroughly researched vaccines and their safety, still thinks the Amish have prohibition on vaccination. Just for example. Rather than go through all those points, I’ll leave you with this. The “audience” had to be moved to a different location than originally planned. The organizers claimed there were “threats” that caused the move. The Bad Science community, however, noted:

The venue is the offices of a well regarded independent television production company. So Becky Fisseux wrote some of the directors: “I’m writing to express my extreme disappointment that such a well thought of production company as Objective is playing host to this event tomorrow evening.” … continuing with an explanation of the anti-vax nature, and rise of measles ending with …”Should you allow this event to go ahead, I fear your company’s reputation will be seriously tarnished, and respectfully ask you to reconsider your decision.”

She got a reply from a director who was confused… and that they will look into it. She says “Next morning, at about 9am I received emails from two directors saying that their rehearsal studio had been booked via a third party who was known to them, but the person who took the booking was not informed of the nature of the event, nor of the links to Wakefield and the anti-vax lobby. They withdrew the offer of the room.”

It’s not longer about a scientific debate when it comes to vaccines and autism and Mr. Wakefield. It’s about image management. If Penn is any indication, they need a lot of “management” for Mr. Wakefield’s image.

addendum: I forgot to credit the Countering Age of Autism blog for bringing the Penn Point episode to my attention.

Age of Autism Abandon Pretence part II

16 Jun

A while back Kev wrote a piece, Age of Autism Abandon Pretence, pointing out how they are drifting away from any real connection to the autism communities in favor of attacking the vaccine program. It wasn’t shocking then to anyone who reads the Age of Autism blog. It isn’t shocking now.

In her piece, Dr. Mayer Eisenstein’s New Book Merits Close Attention, Anne Dachel wrote:

These are people I’m in touch with everyday and who’ve written on autism and on vaccines. Some I’ve had on my threads for years. And as someone who’s been active in the national autism community for a long time, I’ve seen tremendous changes. More and more people are speaking out. We are now an organized and united group, thanks mainly to the power of the Internet. Our message has severely eroded confidence in the cornerstone of health care: THE CHILDHOOD VACCINE PROGRAM. (And keep in mind that there are many more experts writing about this, people I’ve never been in contact with, all challenging the unwavering safety claims of our health officials.)

Bold added by me.

Previous comments on the Age of Autism blog include:

With less than a half-dozen full-time activists, annual budgets of six figures or less, and umpteen thousand courageous, undaunted, and selfless volunteer parents, our community, held together with duct tape and bailing wire, is in the early to middle stages of bringing the U.S. vaccine program to its knees.

True vaccine safety advocates don’t resort to attempts to bring “… the vaccine program to its knees” or eroding “…the cornerstone of health care”.

Andrew Wakefield in the Sunday Telegraph

14 Jun

Andrew Wakefield has been much in the news lately. “Much” is a relative term. He hasn’t been in the news to the level of his hey-day when the his MMR hypothesis was new and given some credibility. But with the decision of the GMC to remove him from the medical register, he has been back in the news. Mr. Wakefield apparently decided to ride this expected wave of publicity by timing his book to coincide with the decision.

Mr. Wakefield’s book tour was not very extensive, and involved some minor and strange outlets, including “Coast to Coast“, a late-night American radio show that bills itself as “Coast to Coast AM – UFOs, strange occurrences, life after death and other unexplained phenomena. Overnight talk radio with daytime ratings”

His tour has not gone unnoticed by the mainstream media. The Sunday Telegraph has a story about him (unfortunately not online as yet):

Needle and Dread
In Britain he’s been struck off and widely discredited. In the US Andrew Wakefield, MMR Pariah, has been reborn–as an unapologetic figurehead for the ‘anti-vaccine’ movement. It’s a long way from Harley Street, reports Alex Hannaford.

If that title isn’t clear enough, the article opens with a picture of Mr. Wakefield with the caption: “Poster boy Andrew Wakefield continues to spark religious-like fervour among supporters

Once, Mr. Wakefield was able to obtain favorable press at least somewhere in the mainstream press.

Times have changed.

NIH funded research includes search for possible vaccine-autism link

11 Jun

Much time is spent discussing whether a study of autism and vaccination status could or should be undertaken. Generation Rescue has been trying to get funding for such a study, but their proposal is weak and vague. The question arises, why doesn’t any group with real strong credentials consider this project?

Would you be surprised to find out that it is already ongoing? And that the principle researcher is someone with mainstream credibility?

It turns out that potential environmental causation of autism, including vaccines, are a part of a study which (if all went according to schedule) just finished the data collection phase. The NIH funded project, GENE-ENVIRONMENT INTERACTIONS IN AN AUTISM BIRTH COHORT, was headed by Prof. Ian Lipkin of Columbia University. The project started in 2003 and was prospectively monitoring a cohort of children diagnosed with ASD’s and another cohort of controls.

The project is discussed below:

Reports of increasing prevalence of autism spectrum disorders (ASDs), a set of highly genetic conditions, are intensifying interest in the role of environmental exposures, including infectious, immune, and toxic factors. Retrospective studies exploring associations between environmental factors and ASDs are compromised by selection bias, small sample sizes, possibly invalid diagnosis, and absence of biologic measures. This prospective study will employ an unselected birth cohort of 75,500 in which cases are ascertained through screening of the entire population, diagnoses established using uniform procedures, extensive histories and clinical data obtained, and biologic samples collected serially throughout pregnancy and early childhood. The application of high throughput laboratory assays to derive maximal information from developmentally-influenced, finite, and nonrenewable biologic samples, and inclusion of early screening and diagnostic assessments, will permit an unprecedented, rich view of the longitudinal trajectory and nascent signs and symptoms of ASDs, facilitate discovery of biomarkers, and afford unique insights into the role of gene:environment interactions in ASD pathogenesis. Specific aims are to: (1) establish the autism Birth Cohort (ABC) through ascertainment of cases of autism spectrum disorder (ASD, N=150-233) and selection of controls (N-1000) from the Norway Mothers and Child (MoBa) cohort; (2) examine biologic pathways that may predispose to ASD, through evaluation of immune, endocrine, and neuroregulatory factors in mothers during early gestation or at birth and in children, at birth or 30 months postnatal; (3) identify environmental factors that may be directly or indirectly associated with ASD, including pre- or postnatal infection, vaccination, very low birth weight or other obstetric risk factors in which infections are implicated, dietary and/or environmental exposure to methylmercury; (4) describe the natural history of clinical, anthropometric, and neurobehavioral features of ASD; and (5) explore genotypic influences that may be directly or indirectly associated with ASD by testing associations of ASD and/or its endophenotypes with family history of autoimmune disease or selected candidate genes, and investigating conditional gene-environment effects using antecedent factors found to influence ASD risk.

Emphasis added.

Prof. Lipkin was a member of the team which looked at children with gastrointestinal disorders, Lack of Association between Measles Virus Vaccine and Autism with Enteropathy: A Case-Control Study. Amongst other findings, they found that (a) regression was not correlated with MMR vaccination and (b) persistent measles infections are not present in the guts of autistic kids more than in non-autistic kids. Basically it was the study that most closely replicated some of Mr. Wakefield’s team’s efforts and showed that Mr. Wakefield’s results were not reproducible.

Another study, THE CHARGE STUDY: CHILDHOOD AUTISM RISKS FROM GENETICS AND THE ENVIRONMENT, includes “vaccines” in the project terms. This study has been funded to the tune of about US$5,000,000 and is headed by Prof. Irva Hertz-Picciotto, who has stated that vaccines should be considered for research into autism causes.

If you are wondering if mercury is being investigated, AUTISM IN A FISH EATING POPULATION continues study on methyl mercury exposures in the Seychelles. Also, the University of Washington has a study ongoing, NEUROIMMUNOTOXICOLOGY OF MERCURY. Johns Hopkins has a study now going on 4 years, GENETIC SUSCEPTIBILITY TO MERCURY-INDUCED IMMUNE DYSFUNCTION IN AUTISM & ASD. Also, the University of Texas has a study, EPIDEMIOLOGICAL RESEARCH ON AUTISM IN JAMAICA, which also is monitoring heavy metal exposures.

I have two questions. First, why do groups like Generation Rescue, SafeMinds, the National Autism Association and TACA claim that vaccine-autism and mercury-autism research isn’t being done? They are represented on government committees. Second, what do they hope to learn from doing their own study that isn’t going to be done better and sooner by other groups?

Generation Rescue’s Vaccinated/Unvaccinated Study

8 Jun

Generation Rescue and other groups have been calling for an independent study of health outcomes comparing vaccinated and unvaccinated populations. They recently announced at the AutismOne conference that they had announced that they had procured funding for the project. They had been trying to get funding for this project from a settlement from a lawsuit against Airborne. The funds from that lawsuit have not been distributed yet. So if Generation Rescue has funding, it is from some other source.

That said, documents filed in Generation Rescue’s bid for the Airborne settlement money gives us a chance to see their proposed study design. Let me pull some of the highlights out for discussion.

The “purpose” of the grant is listed as:

Funding for study on vaccinated verse (sic) unvaccinated children to ensure the safely and well being of children worldwide.

They request $809,721 for the project.

Here is a segment of the statement of the problem to be addressed:

The U.S. and many other countries appear to be experiencing a silent pandemic with 1 in 5 children now suffering from learning disabilities, sensory deficits, and developmental delays. Neuro-developmental disorders such as autism, attention deficit hyperactivity disorder (ADHD), mental retardation, and cerebral palsy, are increasingly common, very costly, and cause lifelong disability. In 2003, the National Survey of Children’s Health reported that 0.5% (I in 200) children ages 6-17 had autism, 11.5% had learning disabilities, 8.8% had ADHD, and 6.3% had behavior problems. By 2007, the prevalence of autism in the U.S. had risen to 1 in 150 children (Rice et aI., 2007). There are a number of physical ailments that children with Childhood Neuro-developmental Disorders (NDs) typically manifest including: food allergies and eczema, general gastrointestinal distress, constipation and diarrhea, yeast overgrowth, immune system deregulation, sleep disturbances, and high levels of environmental toxins.

Why study vaccines? According to the proposal:

What could be causing these increases in NDs and disability among children in the US.? Hypotheses proposed to explain these increases have included changes in diet coupled with reduced physical activity and/or increased sedentary behavior, low birth weight, stress, medication use in pregnancy, infections and environmental toxins. Although it remains widely debated, certain routine childhood vaccinations have been suggested as contributing to the increase in neuro-developmental disorders. A recent examination of the vaccinating practice of other countries showed that the United States vaccinates children on average double that of all other first world countries; the U.S. uses 36 compared to 18 at other countries. In fact, the United States utilizes more vaccines than any other country in the world yet it has the worst mortality rate among children 5-years-old and under of the top 30 developed countries. Coincidently, some of the countries with the lowest vaccination rates also report the lowest rates of autism. It has been theorized the child’s body is overwhelmed by the combination of heavy metals (mercury, lead aluminum), live viruses (particular from their vaccines), and bacteria. These serve to slow or shut down normal biochemical pathways leading to NDi physical and mental manifestations.

I believe the “recent examination of the vaccinating practice” mentioned in the above paragraph refers to the pseudo-study Generation Rescue generated “AUTISM AND VACCINES AROUND THE WORLD: Vaccine Schedules, Autism Rates, and Under 5 Mortality”, which I discussed at length here. Generation Rescue’s “examination” was amazingly manipulative. For example, they compared a recent study on the autism rate in the U.S. for children born in 1994 to a French study from 1997 on children born between 1976 and 1985. Of course the rate in the US was higher than the rate in France. That doesn’t have anything to do with their current vaccine schedules.

What are Generation Rescue’s research credentials?

Research Programs: With some of the top scientists in the world, research is dedicated to finding more of the causative factors and treatment approaches for children with NDs.

Sort of vague there. I note that Generation Rescue decided not to tout their phone survey as an example of their research efforts. Given that in many cases the survey showed exactly the opposite of what Generation Rescue claimed in their cherry-picked publicity, this is understandable. It is still interesting that Generation Rescue seems to realize that the survey was not an asset.

That said, who are “some of the top scientists in the world”? Although not named in the proposal, it is worth checking who these “top scientists” might be. From their website, here is s Generation Rescue’s “Science Advisory Board”?

Richard Deth, Ph.D.
Professor, Department of Pharmacology, Northeastern University, Pharmaceutical Sciences

Brian Hooker, Ph.D.
Principle Consultant
Brian Hooker Consulting

Jerry Kartzinel, M.D.
Pediatric Partners of Ponte Verde

Woody R. McGinnis, M.D.
Research Coordinator, Behavioral Nutrition

I’ll leave it to you to look these gentlemen up, but they are perhaps not what most people would call “top scientists in the world”. Their papers are not very highly cited autism. Also, Generation Rescue does not appear to be using their “top scientists” for this project. Which begs the question: what is the actual project?

I. Project’s Primary Purpose, and the Need it Addresses. The goal of this project is to test the association between vaccinations and both acute and chronic neuro-developmental disorders and the efficacy of preventive health strategies. This will be achieved by conducting a retrospective cross-sectional study comparing the incidence of chronic illnesses (i.e., asthma, obesity, and eczema), neuro-developmental disorders (i.e., autism, ADHD and learning disorders), and overall health and well-being among a random sample of vaccinated and unvaccinated children (5-18 years of age). The study will obtain information from a random sample of two populations: I) children being horne-schooled and belong to the National Horne Educational Research Institute (NHERI); and, 2) children among the 30,000 unvaccinated patients being provided health care at the Homefirst Health Services in Chicago. Data will be collected from medical charts and parental reports via website health surveys and the standardized measures including the Autism Diagnostic Questionnaire.

The project proposal is vague and very brief. But let’s consider some details presented.

Not surprisingly, they chose to work with the Homefirst clinic in Chicago. Homefirst comes up quite often in discussions of proposed vaccinated/unvaccinated studies. This results largely from the fact that the director of Homefirst, Dr. Mayer Eisenstein has stated with no equivocation that there are zero autistic children who were born in his clinic and didn’t receive vaccines.

There is some confusion about how many of Homefirst’s patients are actually unvaccinated. Generation Rescue states that 30,000 are unvaccinated, but this is actually the estimate for all the children at Homefirst, vaccinated and unvaccinated:

“We have a fairly large practice. We have about 30,000 or 35,000 children that we’ve taken care of over the years, and I don’t think we have a single case of autism in children delivered by us who never received vaccines,” said Dr. Mayer Eisenstein, Homefirst’s medical director who founded the practice in 1973.

For the moment, let’s take Dr. Eisenstein at his word. What possible biases are there that they should be working around? One example–we don’t know the status of patients who have left Homefirst. Consider the parents who joined Homefirst specifically to avoid autism. After their child is diagnosed, is it conceivable that they not return to Homefirst and would find a different clinic? How do they plan to control for this? Also, one can not minimize the fact that Dr. Eisenstein has a lot riding on the reputation that he has built on the “no vaccines, no autism” slogan.

Even without this, researchers I have been in contact with have questioned how useful clinical notes such as these could be in screening, much less diagnosing, autism. From what I can see, Dr. Eisenstein’s practice does not include psychologists or other staff to test for autism, so that would not be directly included in the notes.

As an aside, the lack of autistics in his practice hasn’t stopped Dr. Eisenstein from joining the alternative treatment of autism. The Chicago Tribune discussed Dr. Eisenstein, his somewhat troubled past and his foray into treatments like Lupron in Autism doctor: Troubling record trails doctor treating autism.

NHERI is a new name to me. I have not heard much about them or their founder in autism discussions before. As an aside, one quote from the NHERI website was quite interesting–“”Whoever has the data controls the policy.” Kay Coles James, Virginia State Cabinetmember”.

The “Autism Diagnostic Questionnaire” is not a standard diagnostic instrument by any means. In fact, it is difficult to find out what it is at all. A google search for “Auism Diagnostic Questionnaire” gives only two hits (or did before I published this piece). The questionnaire appears to be this worksheet from the Autism Research Institute (DAN). I can find no information on how it is scored or how accurate it is.

One thing missing in this proposed study is actual contact with the children. “Standard measures” could mean a lot of things, but if they were planning on screening children and then testing probable cases using an ADOS and ADI-R (which one might argue would be “standard”), wouldn’t they mention that? If so, wouldn’t they mention who would perform such tests. None of the staff assigned to this study appears to be a psychologist, for example. The Staff for the project are listed as:

Project Stafjing: The Project Director will have a Masters’ degree and will be responsible foroverseeing the implementation, quality assurance and reporting of this project. Dr. A. Mawson is Professor of Pediatrics and Medicine at University of Mississippi Medical Center (UMMC), and Principal Investigator of the Mississippi Study Center for the National Children’s Study. Dr. B. Ray is President of the National Home Education Research Institute and an experienced researcher in home education. Dr. S. Buttross is Professor and Chief of the Division of Child Developmental Disorders in the Department of Pediatrics; UMMC; and Dr. W. May is Professor of Biostatistics, Department of Medicine, UMMC. The combined experience of these investigators ensures the highest standards of quality and scientific rigor.

Generation Rescue and others have often called for an “independent” research. Left unvoiced is whether “independent” means “independent of the government and pharmaceutical companies” or whether “independent” includes being free from ties to the vaccines-cause-autism groups.

The “Project Director”, Dr. Mawson, is a vocal supporter of Andrew Wakefield. Below is a letter by him you can find in multiple places on the web. Note this was not included in the research proposal:

Dear Dr. Crippen,

I would like to point out that Trisha Greenhalgh’s assessment of Andrew Wakefield’s paper was itself seriously flawed!

You do a disservice to Wakefield and the scientific community by perpetuating this myth of the flawed study and the paper that should have been “rejected” by The Lancet.

The paper is actually excellent–a superb case study that will join the ranks of other famous case studies, such as the link between rubella infection and congenital rubella syndrome (Gregg 1941) and between exposure to thalidomide and embryopathy (McBride 1956).

Greenhalgh states that the paper set out to test a hypothesis that was unstated –of a causal relationship between exposure to MMR and autism — and the design of the study was all wrong. She starts out with an incorrect assumption about the nature of the study and then continues to build on her incorrect foundational argument. Her argument may look impressive to the layman and most medical practitioners perhaps, but not to anyone who knows anything about study design, i.e. epidemiologists, and the reviewers of the paper for The Lancet, who clearly understood that the paper was not an hypothesis-testing paper but a hypothesis-generating paper. It was, in short, a case series analysis.

The paper, once understood in this light, as case series analysis, is truly remarkable, well written and brilliantly documented. It concluded by stating the hypothesis, based on parents’ reports, that the children’s’ signs and symptoms were temporally connected to MMR vaccination. Subsequent studies may not have substantiated the hypothesis; but that does not detract from or invalidate the merits of the paper as a case series and as, essentially, a hypothesis paper.

Anthony Mawson.

I’d be interested in Prof. Mawson’s take on the quality of the Wakefield Lancet article now that it has been retracted. More to the point, the fact that the study is not a true “case series” in the fact that the subject selection was highly biased. There is an “Anthony Mawson” who is a signatory on the “We Support Andy Wakefield” website.

Dr. B. Ray is the President of NHERI, the homeschooling group involved in the research and is not a medical professional nor an epidemiologist.

Dr. Susan Buttross appears to be rather reasonable. The website for a clinic she is affiliated with has links to sites like the CDC and the AAP when discussing vaccines and autism. She worked on the Mississippi Autism Task Force, whose report can be found here. That report does not discuss vaccines one way or the other. It does discuss that toxins have been “implicated”:

To further complicate the findings, there is mounting suspicion that environmental factors play a role in many cases. A genetic predisposition may cause certain individuals to be more sensitive to environmental toxins. Specific environmental toxins have not yet been identified, however, lead, mercury, and other chemical toxins have been implicated. There has been concern that certain dietary components may be a causative factor in some cases. Viral infections including rubella, measles, and CMV (cytomegalic virus) have also been linked to ASD. Illicit drugs and alcohol used by the mother during pregnancy are also known to increase the risk of a child developing ASD.

Interviews with her can be heard here, here and here.
Mississippi Autism Task Force

Dr. W. May is, I believe, Warren May. I have no real details on what connection he may have to the autism communities and to the question of vaccines.

In the introduction I pointed out that Generation Rescue was attempting to get funding for this project from the Airborne settlement. The Ariborne suit was brought by the Center for Science in the Public Interest (CSPI). CSPI was not supportive of the Generation Rescue proposal, noting that the project was vague and the sample groups likely heavily biased and that Generation Rescue was not actually conducting the study, but was managing it, building in overhead costs that might not be warranted.

I tend to agree with CSPI that the proposed study is far from being strong enough to be very convincing, one way or the other, on the question of vaccines and autism. There are some potentially reasonable people associated with this proposal. But I would think that any active involvement by Dr. Mayer Eisenstein would seriously taint the study. Further, should Dr. Mawson still support Andrew Wakefield, given Wakefield’s multiple ethical lapses and clearly biased study design, I would think that too would cast somewhat of a pall on the study.

Can an study comparing outcomes of unvaccinated and vaccinated populations be performed? Like any study, a lot depends on how definitive the answer you want is. Prometheus at the Photon in the Darkness blog has discussed the limitations of these studies and, also how they could be done. One early example is in his post “Let’s put on a Study!” Dr. David Gorski goes into the details as well in The perils and pitfalls of doing a “vaccinated versus unvaccinated” study. I agree with his conclusions:

Still, if the government caves and decides to do such a study, it is up to us in the scientific community to make sure that it’s done by no one but the best epidemiologists, in other words, that it’s a proper study that correctly controls for confounders and can answer the question being asked, not the dubious study custom designed to have the maximal chance of a false positive result, which is of course what the anti-vaccine movement really wants.

The questions raised by a vaccinated/unvaccinated study are far to important to be handled by anything less than the best researchers with access to the best data. I fear that Generation Rescue’s plan doesn’t meet either count.

Urine test for autism? Hmmm

4 Jun

Following on from Lisa Jo’s well placed concerns about this study,I also have a few. Namely the references. Not being scientifically qualified to tackle the meat of the paper I look straight at what the researcher uses to support his ideas. So far I’ve found these references the authors base their paper on:

1) Kidd, P. M. Autism, an extreme challenge to integrative medicine. Part: 1: The knowledge base. Altern. Med. Rev. 2002, 7 (4), 292–316.

2) Ashwood, P.; Anthony, A.; Pellicer, A. A.; Torrente, F.; Walker-Smith, J. A.; Wakefield, A. J. Intestinal lymphocyte populations in children with regressive autism: evidence for extensive mucosal immunopathology. J. Clin. Immunol. 2003, 23 (6), 504–17.

3) Bolte, E. R. Autism and Clostridium tetani. Med. Hypotheses 1998, 51 (2), 133–44

4) James, S. J.; Cutler, P.; Melnyk, S.; Jernigan, S.; Janak, L.; Gaylor, D. W.; Neubrander, J. A. Metabolic biomarkers of increased oxidative stress and impaired methylation capacity in children with autism. Am. J. Clin. Nutr. 2004, 80 (6), 1611–7

At the very least, relying on studies from Alternative Medical Review, studies co-authored by Andrew Wakefield, studies from Medical Hypothesis and studies co-authored by Jim Neubrander should give rise to questions over the credibility of this paper. Is it enough to scupper it? Of course not. But when we take Lisa Jo’s questions into the bargain – that autism does not always, if ever, have a distinct GI component, I have to wonder about this paper.

Addressing the ‘too many too soon’ hypothesis

3 Jun

Regular readers may be aware that I blogged about a study recently that demonstrated the early stages of tackling the ‘too many too soon’ hypothesis. It came in for some fierce criticism in the comment section so I wrote to the lead author to get his thoughts. What follows is his answer to me via email:

Reviewing your blog, there are two related criticisms of our study.

First, I must clarify the conflict of interest comment. Though less relevant in my mind, it addresses the other limitations noted by your readers. This study was completely unfunded – not by any pharmaceutical company, not by the CDC. We did this all in our free time because of a simple non-financial “conflict” – as infectious disease physicians we take care of children who suffer needlessly from vaccine preventable diseases. This clarification of funding leads to point 2 – because we
did not have millions of dollars at our disposal we chose to use pre-existing data to address a common parental concern for which we could not find any evidence-based talking points.

This strategy had significant benefits – once we had the idea for this study we got right to work and did not have to wait 7-10 years to see what the outcomes might be. However, as we acknowledge in the discussion (and your readers point out), the use of pre-existing data also introduces limitations. We did not have control over which outcomes were tested, nor which children were included or excluded from the original study.

Nevertheless, I believe this study was accepted for publication in an academic medical journal because it offers a unique methodology that may be used to study the effects of delayed vaccination on any outcome of choice, whether it be the incidence of vaccine-preventable diseases or the proposed vaccine side effect du jour. Unfortunately, I do not have the resources to perform these studies myself.

A separate question – which is really a critique of the original NEJM study (with which I was not involved) and not ours per se – is why the authors chose to exclude the children they did. In the time since you e-mailed be I believe “Luna_the_cat” has explained this fairly clearly. Basically, the original study excluded children with brain injuries that would not have been related to vaccination (except for a few – pneumococcal and haemophilus influenza meningitis which vaccines PREVENT) and this seemed reasonable in the initial study. Furthermore, the majority of these exclusion criteria are prenatal or congenital diagnoses that would have predated vaccination anyway.

Finally, regarding lack of “controls”. This was not a “vaccinated versus unvaccinated” study, nor was it intended to be. It was designed to address the “too many too soon” hypothesis. Our “controls” were those children in the cohort who received fewer vaccines later during the first year of life. In this case the “exposure” was timely vaccine receipt – which was never associated with any adverse neurodevelopmental outcomes.

AutismOne Generation Rescue conference expells registered attendees

2 Jun

Autism News Beat has this story in full in Listening to parents at AutismOne. AutismOne is a parent convention with a major focus on alternative medicine. To put them in perspective, Jenny McCarthy is a frequent keynote speaker and Andrew Wakefield was honored by AutismOne last year after it was revealed that his study was possibly tainted by misreporting of results.

If you recall, AutismNewsBeat was expelled from a previous AutismOne conference. He had just asked, respectfully, an important question of Hannah Poling’s mother (Hannah Poling is the child whose case before the vaccine court was conceded on the basis of vaccines aggravating an underlying mitochondrial disorder). To my knowledge, AutismNewsBeat has no been given a clear reason for the expulsion.

A filmmaker/Journalist was present at this year’s AutismOne. Lars Ullberg had applied for press credentials and was denied. AutismOne responded to this request stating:

Autism One is not prepared to offer press passes to you or your crew. Although you and each of your crew members may pay the registration fee as regular attendees, subject to the usual terms of attendance, neither you nor your crew members are permitted to conduct any videography, photography, audio recording, or press interviews; furthermore neither you nor your crew members are permitted to quote attendees, presenters, exhibitors, volunteers, or staff in any manner that will be quoted, “on the record,” or used for public or private media or instructional purposes. Additionally, you and your crew members must identify yourselves accurately with your affiliations to those to whom you speak and also not mislead them to think that you are simply seeking information with which to help your child. Finally, you may not eavesdrop on private conversations between attendees. In summary, Autism One grants no permission to you or your crew to report on this conference or its attendees. Should we become aware that you are not following these guidelines, we will not hesitate to ask you to leave the conference.

AutismNewsBeat asked AutismOne for details on why Mr. Ullberg was removed from the conference, but he has yet to receive a response.

I find the wording and possible intent of this sentence rather odd: ” Autism One grants no permission to you or your crew to report on this conference or its attendees”. If an attendee chose to be interviewed, would that not be OK? The conference appears to be speaking for its attendees.

In addition, a public health official was in attendance for this year’s AutismOne conference. This person also was asked to leave. According to AutismNewsBeat:

A staff member of a western state department of public health was reportedly attending a session on vaccines and parental rights. According to one source, the speaker was advising parents how to apply for and receive vaccine exemptions. The session was interrupted by an AutismOne organizer who commandeered a microphone to announce that a state health department staff member was present, so parents should be careful about what was discussed.

A short time later four Westin O’Hare security guards entered the room, identified the staffer, and directed her to leave the conference facility.

Perhaps in the case of the journalist, AutismOne was afraid of bad press. But haven’t parent groups been asking for some time for people to listen to them? A public health official attends the conference in order to listen and is expelled.

Generation Rescue and Autism One appear to be working in a very defensive, entrenched mode. Internet chatter is mentioning closed sessions where Andrew Wakefield spoke. Closed sessions? Expelling journalists? Refusing permission for journalists to report on what attendees have to say–even if the journalist clearly identifies himself? Asking public health officials to leave for no apparent reason? Again, this comes across to me as an entrenched, defensive mindset.

Andrew Wakefield – as succesful an author as researcher

Andrew Wakefields supporters were hoping his new book would be a bestseller. That ain’t going to happen given how much a publishing insider revealed to me how many he has actually sold:

He sold a total of 1017 copies. Top sales 157 copies in NYC. 46 in LA, 43 in Atlanta (perhaps CDC people wanted to see what he said?!), 38 in Boston, 24 in Chicago, 18 in Seatlle and 17 copies in his hometown of Austin

Ouch. It’ll be interesting to see how well the book does as interest in it fades. Or maybe ‘well’ isn’t the right word.
