Autism & Mercury – Wagnitz Challenges Fombonne

The mercury autism debate continues. While not a subscriber to the mercury vaccine/autism link I do not think debate and discussion should be closed on this or any other subject related to autism. Toxicologist Michael Wagnitz seems somewhat more qualified to present information on the “mercury” side of the debate than David Kirby and presents some interesting points in rebuttal of Psychiatrist Dr. Eric Fombonne.

The mercury, autism debacle: How stupid do they think we are?

Last weekend the Sixth International Meeting for Autism Research took place in Seattle. The meeting claimed to draw the top 900 autism researchers and scientists from around the world. One of the key participants was Dr. Eric Fombonne of Montreal Children’s Hospital at McGill University. Dr. Fombonne, a psychiatrist, presented his research on mercury. His work involved testing the blood and hair of 147 children. Roughly half of his subjects were diagnosed with autism and half were considered neurologically typical controls. He found no difference in mercury levels in the patients hair or blood.

The first question one might ask is why a psychiatrist is considered qualified to do toxicological work. Most parents are concerned about the mercury exposure that their children received as newborns and infants from mandatory vaccines. The vaccine schedule in Canada, where Dr. Fombonnes study was done, and the United States were quite different in the 1990’s. Dr. Fombonne,s patients were not tested after vaccination. If he had talked to any reputable toxicologist, they would have told him that the ethylmercury from vaccines clears the blood in about seven days. Ethylmercury, a short-chain alkyl mercury compound, is rapidly distributed to the brain, kidneys and other tissue. The hair tested would need to be from a first haircut to show this mercury exposure. Even if this was the case, research has shown that autistic kids do not excrete mercury efficiently. The hair would not contain any measurable amounts of mercury. It’s to bad that McGill University does not have any toxicologists who could have explained to Dr. Fombonne that his work was a waste of time and money.

If one was really interested in determining the body burden of mercury they would perform the urinary porphyrin profile analysis (UPPA). Porphyrins are precursors to heme, the oxygen carrying component of blood. Mercury inhibits the conversion of specific porphyrins to heme. This test is backed by decades of published research. Recently it was shown in two published, peer-reviewed studies, that mercury inhibited porphyrins were significantly higher in autistic patients when compared to age matched controls (1)(2). The other way to test for mercury in the body is by using a provoking agent and measuring mercury in the urine.

The organizers of this meeting did not reveal that when Dr. Fombonne isn’t conducting epidemiological studies or doing heavy metal analysis, he is appearing on behalf of vaccine manufacturers defending the safety of mercury. Dr. Fombonne refers to the amount of mercury in vaccines as “trace”. Again, if he were a toxicologist or chemist, he would realize that the concentration of mercury in a multi-dose vaccine vial is 250 times higher than what the United States Environmental Protection Agency (EPA) classifies as hazardous waste.

Autism & Thimerosal – Geier & Geier (2007) Study Suggests A Link?

One of the great debates in autism discussions has been between those who believe that mercury based vaccine preservatives cause or contribute to incidents of autism and those who do not subscribe to that theory. The overwhelming consensus from the scientific community has been that there is no evidence to support such a link. Notwithstanding that consensus there are still a large number of parents of autistic children ( I am not one of them ) and one journalist/author (David Kirby) who believe that there is indeed a link. A few of the parents have been very vocal. Some, if internet discussions can be believed, have gone as far as harassing and threatening those who oppose their views. At least those are the allegations advanced by some “neurodiversity” commentators some of whom are equally as hostile and rude to those who disagree with their views as the extremist few among the mercury-thimerosal advocacy groups. Now, another study by Geier & Geier (2007) apparently suggests that there is a causal connection between Thimerosal and autism. Hopefully, this study will be neither rejected nor accepted based solely on prior belief. Hopefully the scientific professionals capable of properly analyzing this study will do so and offer their commentary. Hopefully hostility and hatred between the few extremists in both the mercury-vaccine and the neurodiversity groups will stand aside in favor of reason and proper scientific assessment of this study and any further evidence relevant to this issue which might arise.

The following commentary, however, appears to indicate that the old pattern of jumping to conclusions about issues in the mercury-autism debate, based on ideological pre-disposition will, unfortunately, continue to prevail and that the world autism community will be inflicted with more needless hostility between the mercury and neurodiversity groups. The author’s readiness to conclude that the study “leaves little doubt” does not suggest the kind of reasoned professional analysis that will be needed to properly interpret and assess the study.

The Journal of Toxicology and Environmental Health, Part A: Current Issues, an authoritative journal featuring original toxicological research, has published, “A Case Series of Children with Apparent Mercury Toxic Encephalopathies Manifesting with Clinical Symptoms of Regressive Autistic Disorders,” by Geier and Geier (2007).

This new study leaves little doubt there is a direct causal link between mercury exposure from Thimerosal-preserved biological products (vaccines and Rho(D) products) and mercury poisoning diagnosed as an autism spectrum disorder (ASD).

Thimerosal (49.55% mercury by weight) is a highly toxic mercury compound used as a preservative in some OTC and prescription drugs, including most flu shots given to pregnant women, infants, children, adults, and the elderly.

On April 19, 2007, Dr. Larry L. Needham, Chief, Organic Analytical Toxicology Branch, CDC, announced to the US National Academy of Sciences’ Institute of Medicine that Thimerosal was among the “Chemicals Linked to ASD.”

Thus, Geier and Geier (2007) provide the first clinical case-series of ASD patients that confirmed this causal role for Thimerosal-preserved drugs in patients having a regressive ASD diagnosis.

The Geiers describe a case-series of eight patients who had:

— a regressive ASD diagnosis,

— elevated levels of androgens,

— excreted significant amounts of mercury after a chelation challenge,

— biochemical evidence of decreased function in their glutathione pathways,

— no known significant mercury exposures except from Thimerosal-preserved vaccines and Rho(D)-immune globulin preparations, and

— alternative causes for their regressive ASDs ruled out.

This clinical study also found a significant dose-response relationship between the severity of the ASD symptoms and the total mercury dose these children received from Thimerosal-preserved drugs.

Based on differential diagnosis, these patients were exposed to significant mercury amounts from Thimerosal-preserved biologic drugs during their fetal and neonatal development as well as between 12 and 24 months of age. Thus, these initially normally developing children suffered mercury toxic encephalopathies that manifested with clinical symptoms consistent with their regressive ASD diagnosis.

Hence, mercury poisoning should be considered as a cause for those children exhibiting the symptoms of an ASD in any differential diagnosis designed to assess underlying causes.

Today, any parent or other healthcare provider can easily confirm whether, or not, a non-chelated autistic child is mercury poisoned by having urinary porphyrin profile analysis (UPPA) testing run at LabCorp (Test#120980) or Laboratoire Philippe Auguste (Urine Porphyrin Profile).

Evidence of Harm – The Sequel

In recent years theories that autism increases have been caused by either the MMR vaccine itself or thimerosal, the mercury based vaccine preservative, once more widely used, has dominated much public discussion of autism – despite an almost total lack of support for the vaccine causes autism theories amongst the world scientific community. But the controversy generated by the Wakefield study and the David Kirby/Robert Kennedy Jr anti-mercury campaigns has had an impact – on famlies already stressed by the realities of their children’s autism and on a decline, at least temporarily, in the numbers of persons getting their children vaccinated against serious, dangerous diseases. Evidence of harm? You bet. Not the kind Kirby and Company rant about on the Huffington post though.

Study reveals impact of the MMR controversy on parents of children with autism
Medical Studies/Trials

Published: Thursday, 29-Mar-2007

Researchers have found that the MMR controversy caused parents of children with autism feelings of stress, guilt and frustration. Their study is published in Archives of Disease Childhood.

In the course of 10 focus group discussions across the UK between 2003 and 2005 involving 38 parents of children with autism, scientists from the Medical Research Council (MRC) discovered the effects of the uncertainty caused by the MMR controversy on these parents. Their aim was to assess how the parents had been affected and identify their specific needs to inform how these might be met in future debates around immunisation.

In 1998, Andrew Wakefield and his colleagues published an article in which they claimed to have found a link between the MMR vaccine and the onset of autistic spectrum disorder, although most of his co-authors subsequently disassociated themselves from the suggestion that there was a link between the vaccine and autism.

The controversy that followed affected parents’ decision-making with regards to MMR vaccination. The Health Protection Agency’s figures show immunisation rates across the UK population fell from 92% before the controversy, to 80% by 2003/04 (http://www.hpa.org.uk/infections/topics_az/vaccination/cover.htm). Vaccination rates have since started to increase again as parental confidence in the vaccine has begun to recover. However, until now no research had looked at the impact of the MMR controversy on the parents of children with autism.

Dr Shona Hilton and her colleagues at the MRC Social and Public Health Sciences Unit in Glasgow found that many parents of children with autism have come under great stress and pressure as a result of the scare.

Dr Hilton found that some have experienced agonising uncertainty as to whether the MMR vaccine may have provoked their child’s or children’s autism. Many have wondered whether they are to blame for their child’s condition or felt they had “let their children down” by deciding to vaccinate. Even those who felt that their child’s autism was not linked to the MMR vaccine, either because of family history or because they had avoided vaccination, had suffered as a result of the ambiguous advice they felt that they had received.

The discussions also showed that most parents found it extremely difficult to make subsequent decisions about further vaccination for their children with autism and later children. Many parents felt let down by health professionals and health visitors as well as GPs. This appeared to be a result of the lack of clarity and consistency in what they were told. It may also have been a result of the perceived lack of empathy with and understanding of the realities of caring for a child with autism.

Dr. Hilton said: “It is clear from a review of the literature that there has been a lack of follow-up of the impact of this health scare on those likely to be most directly affected – those living day in and day out with children with autism. These parents in particular have been under a huge amount of stress about the possible impact of their decision to vaccinate or not. Often, those they turned to for guidance and advice, their health visitors and GPs, were not able to provide them with the support they needed.

Dr Hilton added “we are planning to conduct further research into whether health professionals feel that they are well-enough equipped to deal with parents during such health controversies, and how they can be better-supported. We hope to be able to develop new information materials and to identify other support that health professionals need in the difficult task they face of communicating with parents at the height of any future health controversies.”

The Autism Vaccine Link – A Dangerous Urban Myth

The vaccine-autism debate has been raging for years despite a lack of scientific evidence to support the belief in a link between thimerosal, the mercury based preservative once widely used in vaccines, and increased rates of autism. In New Brunswick a couple of years ago I received some very heated responses when I posted on an autism discussion newsgroup a British Medical Journal article which called into question the existence of any vaccine autism link. But the belief continues on in the media fueled by Robert Kennedy Jr. and David Kirby. Arthur Caplan is a bioethics professor at the University of Pennsylvania and he has written an excellent opinion piece in the Philadelphia Inquirer/Centre Daily.Com in which he describes the vaccine causes autism link as an urban myth and also describes the horrible consequences that have ensued from this urban legend. Many parents fearing the autism link refuse to vaccinate their children against deadly diseases putting them and all of us at risk of an outbreak of these diseases.

“Fact: No link of vaccine, autism

What must it be like to spend a huge amount of time every waking day trying to change public health practice – only to find out that you were wrong?

That is precisely what has happened to the proponents of the theory that mercury in vaccines – contained in the preservative thimerosal, which once was used (and is used no longer) in vaccines – is responsible for a nearly 20-year explosion in autism and other neurological disorders among American children.

This urban legend has had very real – and terrible – consequences. It has led, and continues to lead, many parents to avoid getting their kids and themselves vaccinated against life-threatening diseases. The failure to vaccinate has caused many preventable deaths and avoidable hospitalizations from measles, whooping cough, diphtheria, flu, hepatitis and meningitis. And fear of vaccines puts each one of us at risk that we, our children or grandchildren will become part of a deadly outbreak triggered by someone whose parents avoided getting their child vaccinated for fear of autism.

Recent research on many fronts in medicine and science has nailed the coffin shut on the mercury-in-vaccines-

causes-autism hypothesis. The connection is just not there. Perhaps the key fact, which has garnered little attention, is that thimerosal has been removed from vaccines in this and other countries for many years, with no obvious impact on the incidence of autism. The most recent data point toward a correlation with nothing at all to do with vaccines: the increasing age at which people (particularly men) have children seems to be associated with an increase in autism and other neurological problems.

Still, some of the most fervent anti-vaccine critics cannot let go. They continue to tell devastated parents of children with autism that vaccines are to blame. Others are still out on the lecture circuit peddling books and articles that bash vaccines and invoke mercury as a problem. Still others pepper the Internet with the false message that vaccines and autism do go hand in hand – it is just that the government, or the pharmaceutical companies, or organized medicine, or all of them, are keeping the truth from us all.

Less than two years ago, Robert Kennedy Jr. published an article in Salon.com alleging that the government knew of and covered up the autism-vaccines connection. Thimerosal was, Kennedy told large audiences and many media reporters, to blame.

Kennedy was hardly alone in fingering vaccines as the cause of the epidemic of autism affecting American children. David Kirby’s 2005 best-selling book, Evidence of Harm, and many other articles, newsletters and advocacy blogs fanned the flames. Some continue to do so.

Proponents of the thimerosal/mercury-causes-

autism theory have had a powerful impact on public opinion. When one of my students recently conducted a pilot study of attitudes about the new cervical-cancer vaccine, fears about autism were prominent among the reasons many respondents gave for being wary of the vaccine. Friends of mine continue to tell me of parents in Lafayette Hill, Voorhees, Greenville and Downingtown who won’t have their children vaccinated because of the risk of autism. States continue to allow parents to opt out of vaccines on “philosophical” grounds – perhaps the only arena in American public life where “secular philosophy” is given legal standing in public policy. And even some young health-care workers report that they don’t get important vaccines that would protect them, their families and their vulnerable patients against death because of worries about autism and vaccines.

Science and medicine have not bought the thimerosal/mercury-autism link. For years the Centers for Disease Control and Prevention, the American Academy of Pediatrics, the Children’s Hospital of Philadelphia’s Vaccine Education Center, the National Academy of Sciences, the Food and Drug Administration, and countless other prestigious organizations and scientists have said the data do not support mercury in vaccines as the cause of autism.

Now, with the mercury long out of vaccines, what is there left to say? Why won’t the slandering of vaccines as the cause of autism stop?

There has always been a great deal of antipathy toward vaccines – in part because vaccines do have a tiny chance of causing death or other serious side-effects. Parents who have been through that hell have a hard time hearing or sending any other message other than “vaccines are bad.” And those who made careers out of peddling the vaccine-autism link – in the face of a lack of evidence – have really been motivated by a distrust of medicine, science, government and experts, a distrust that has little to do with scientific studies or expert opinions. Even government officials have never really cared enough about public health to do much to counteract the incredible damage the autism-vaccine proponents have done. That is not acceptable.

Our nation is spending a fortune on plans to cope with the prospect of a bioterror attack. State, city and federal agencies are trying to figure a plan if avian flu mutates into a form in which it can start killing people. Hospital officials are worrying over how to cut back on preventable deaths in our hospitals and nursing homes. Those in charge of keeping disease transmission in hospitals, schools and public spaces to a minimum are fretting over what steps to take. The answer to every one of these challenges involves – vaccines.

This nation’s future, its national security, the safety of its health-care institutions, and the safety of its citizens depends upon vaccination. It is way past time that message got heard by parents, teachers, nurses, doctors, hospital administrators, the media and politicians. If there has been a more harmful urban legend circulating in our society than the vaccine-autism link, it is hard to know what it might be. At a time when vaccines may be our last best hope in facing some of the greatest challenges we and our children face, this legend needs to be put to rest. Vaccination, not vaccine-bashing, is what this nation needs.
