Brief Summary:
The purpose of this study is to determine if human immunoglobulin given by mouth twice a day is effective in treating the persistent gastrointestinal (GI) problems such as diarrhea, constipation, abdominal pain, and bloating, in children with autism.

Condition or disease Intervention/treatment Phase
Autism Autistic Disorder Child Development Disorders, Pervasive Gastrointestinal Diseases Signs and Symptoms, Digestive Drug: Oralgam (human immunoglobulin) Phase 2

Detailed Description:

Autistic GI Dysfunction (AGID) is a term that describes a constellation of GI signs and symptoms often found in children with autistic disorder, including abdominal pain, constipation, chronic diarrhea, alternating constipation and diarrhea, gaseousness, bloating, and reflux.

The objective of this study is to assess the potential efficacy of oral immunoglobulin in reducing a wide range of GI symptoms in children and adolescents diagnosed with autistic disorder.
