BETHESDA, Md., March 5 /U.S. Newswire/ -- The just-released March 2003 issue of
the science journal, Pediatrics, features commentary from Drs. Karen Nelson and
Margaret Bauman on the possible role of thimerosal as a cause of autism.
Thimerosal is a mercury-based preservative used in many vaccines. While Bauman
and Nelson consider the autism-thimerosal link ''improbable'', many scientists
and parent advocacy groups think otherwise and blame its use for the devastating
rise in autism which now affects up to 1 in 150 children.
Thousands of parents have reported biological and neurodevelopmental changes in
their children directly following administration of mercury-containing vaccines.
Symptoms, including sudden onset of shyness, GI distress, loss of motor skill
function, allergies, the inability to speak, tremors and autonomic disturbances,
mimic those associated with mercury poisoning. In 1999, the FDA issued a
statement indicating some children may have been exposed to unsafe levels of
mercury via thimerosal-containing vaccines. Public attention to the thimerosal
issue increased after several congressional hearings and after lawmakers snuck a
provision into the Homeland Security Bill that would protect drug companies from
thimerosal-based lawsuits.
''The Nelson-Bauman commentary has a number of inaccuracies that call into
question the legitimacy of the paper's conclusions,'' said Sallie Bernard,
Executive Director of the advocacy group Safe Minds and the lead author of two
autism-mercury papers cited by the Pediatrics article. ''For example, they claim
that survivors of acrodynia, a form of mercury poisoning, did not have
behavioral disorders suggestive of autism but case descriptions clearly show
that they did, such as loss of speech, odd behaviors, and social withdrawal.
Likewise, the authors remark that mercury studies from the Faroe Islands found
no cases of autism, but these studies by design excluded any children with
neurological disease.''
Lyn Redwood, RN, President of Safe Minds and a co-author of the two
autism-mercury papers, pointed out that the Pediatrics authors base their
argument of thimerosal safety on a purportedly ''weak association'' between
neurodevelopmental disorders and exposure to thimerosal containing vaccines
found by the Centers for Disease Control in an unpublished study. ''The
supposedly weak association is a mischaracterization. Safe Minds obtained an
earlier version of the CDC study that in fact found a 2 1/2 times increase in
the risk of developing autism after exposure to increased thimerosal in
vaccines. In a court of law, a relative risk of 2.0 or greater is sufficient to
substantiate that a given exposure caused disease.''
Many parents are angry that the Nelson-Bauman article compares symptoms of
mercury poisoning to those found in classic but often inadequate descriptions of
autistic children. Lori McIlwain, co-founder of parent advocacy group MOMA, says
that once the word ''autism'' comes up, the medical community puts their
blinders on. ''After receiving a mercury-containing vaccine, my child had
tremors and unusual sweating patterns, which doctors don't associate with
autism, yet they diagnosed him with autism based on the more well-known
symptoms. He was also exposed to thimerosal during pregnancy via my RhoGAM(tm)
injection, and he has almost every symptom listed on the FDA's web site for
prenatal mercury exposure.''
A thorough review of the Pediatrics article is currently underway by Safe Minds.
One area of investigation is the failure of the authors to acknowledge the high
mercury levels found in children with autism. During the Institute of Medicine
review of thimerosal in 2001, Dr. Jeffrey Bradstreet presented a study of 191
children with autism with documented mercury levels 500 percent greater than
those of children without autism.
