Gluten Free Diet in People With Schizophrenia: A Pilot Study

Status Completed

Clinical Trial Summary

Background: Celiac disease is an immune-mediated reaction to gluten, presenting with diarrhea, weight loss, abdominal complaints and a range of less common associated neurologic and psychiatric symptoms. Evidence of a link between schizophrenia and celiac disease dates back to 1961. Recent evidence shows that 5.5% (age adjusted) of persons with schizophrenia participating in the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study had a level of antibodies to tTG that is consistent with a diagnosis of celiac disease (compared to 1.1% of the comparison sample). An unexpected finding was that 23.4% (age adjusted) of the CATIE sample had antibodies to gliadin (compared to 2.9% of the comparison sample). It is hypothesized that a gluten free diet in people with schizophrenia who have Celiac disease or gluten sensitivity will have improvement in symptoms and quality of life.

Objectives: The aim of this proposed pilot study is to establish the feasibility of a initiating and maintaining a Gluten-free diet in these two groups. For this study The investigators will identify 8 individuals who have positive assays to tTG antibodies and confirmed celiac disease (N=4), or positive assays for anti-gliadin antibodies (N=4). The investigators plan to consent at least 2 subjects from each group and ask them to participate in a two-week open label treatment of a gluten free diet. The groups are;

1. Celiac disease (positive tTG antibody); and

2. Positive assay on Antigliadin antibodies
