In vitro platelet function in infantile autism.

• It has previously been demonstrated that patients with infantile autism demonstrate impaired in vivo platelet behaviour. Therefore, in 14 children (13 boys and 1 girl) with infantile autism (aged 2-14, mean 6 years) and 12 healthy control boys (aged 6-15, mean 11 years) we studied in vitro platelet reactivity using ADP- and collagen-induced platelet aggregation. In each child a total of 7 different final concentrations of ADP and 4 different concentrations of collagen were employed. At all concentrations of ADP and collagen used the autistic children consistently exhibited diminished platelet aggregability; the differences, however, did not reach statistical significance. Therefore a wider panel of in vitro tests is apparently required and a larger group of patients be studied to help elucidate the functional/metabolic platelet defect met in infantile autism.
