Abstract
A large number of autoimmune disorders have a gastrointestinal (GI) dysfunction component that may interplay with genetic, hormonal, environmental and/or stress factors. This narrarive review investigates possible links between autism, immune system abnormalities and GI symptoms in a subgroup of children with autism. A literature search on Medline (1950 to September 2010) was conducted to identify relevant articles by using the keywords ‘autism and gastrointestinal’ (71 publications) and ‘autism and immune’ (237 publications), cross-referencing and general searching to evaluate the available literature on the immunological and GI aspects of autism. Sufficient evidence exists to support that a subgroup of children with autism may suffer from concomitant immune-related GI symptoms.

†Anecdotal reports that suggest restricted diets may ameliorate disorder symptoms have not been strongly supported or refuted by the scientific literature to date. The literature also does not fully address the possibility that a subgroup of individuals may respond to such diets.
