Antibodies against Food Antigens in Patients with Autistic Spectrum Disorders
Mean SEM and individual titers of AGA-IgG (anti-α-gliadin IgG) are reported; normal range cutoff is indicated by the dotted line (50 U/mL). (a) The investigated subjects were divided in three groups to be compared on the basis of diet regimen: ASDs children on a regular diet (AU RD) or on GF/CF diet (AU GF/CF) and healthy children (HC RD); AGA-IgG were increased in ASDs versus healthy children (, Kruskal Wallis test, Dunn's multiple comparison test). (b) The investigated subjects were divided in four groups to be compared on the basis of normal/altered intestinal permeability: ASDs children with normal (AU normal) or altered (AU altered) LA/MA values and healthy children with normal (HC normal) or altered LA/MA values (HC altered); AGA IgG titers in ASDs were increased irrespective of intestinal permeability (, Mann Whitney test).
