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).
