Childhood autism: a complex disorder.

Abstract

Twenty-four-hour urine samples from psychotic and autistic children were precipitated with benzoic acid at pH 4.3. Fractionation of the aromatic complexes thus formed with benzoic acid-protein and peptides and uric acid, proteins and peptides on G-25 columns-yielded filtration patterns that may be of diagnostic value. Peptide material could be extracted from the formed complexes and refractionated on P2 gels. Increased levels of peptide material, especially of N-substituted peptides, could be demonstrated. Several bioactive factors (Reichelt et al. 1981) are under study. Possible etiological factors are discussed, and a working hypothesis is presented.
