Autism Reality

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).
