I saw the before and after videotapes of this child and the transformation is remarkable. Environmental toxins might also be important in weakening the immune system. It is possible that several of the yeast metabolites inhibit the Krebs Cycle and thus general cell energy production. The high concentration of the unusual yeast sugar arabinose may inhibit gluconeogenesis. This child had been completely normal until being treated for strep throat at nine months of age.
Severe hypoglycemia can markedly impair neurological function.
In addition the arabinose may have other unknown toxic roles. I have tested infants who lost eye contact with the mother, an early symptom of autism, after antibiotic administration. Nystatin restored normal eye contact. I don't think we can afford to have all the data before we take action. The pharmaceutical industry knew about the yeast overgrowth problem in the 1950's when oral antibiotics were introduced.
