Wheat gluten challenge in schizophrenic patients

Abstract

Eight chronic schizophrenic patients were maintained on a diet free of gluten, cereal grains, and milk (CM-F diet) and challenged in a double-blind manner with dietary wheat gluten and placebo. While on the CM-F diet, each patient received a daily challenge of 30 g of gluten for 5 weeks and a placebo challenge for 8 weeks. No deterioration in clinical status as measured by the BPRS was noted on gluten challenge. Serum alpha 1 acid glycoprotein measurement demonstrated no evidence of inflammatory response to gluten challenge. The data suggest that sensitivity to dietary gluten is not characteristic of young chronic schizophrenic patients.
