Celiac disease and type 1 diabetes mellitus are both autoimmune diseases which have a common genetic predisposition. The aim of this study was to determine the prevalence of manifest and latent celiac disease in type 1 diabetic patients.
Anti-endomysium IgA was tested by indirect immunofluorescence using sections of human umbilical cord for screening in 100 adult patients with type 1 diabetes mellitus and in 80 age and sex matched controls with no known disease. Distal duodenal biopsy, human leukocyte antigen typing, urinary D-xylose excretion test, stool analysis, biochemistry profile, blood counts, serum ferritin level and small intestinal radiography were performed in anti-endomysium IgA positive cases. Small bowel biopsy specimens consistent with celiac disease were defined as manifest celiac disease, while positive antiendomysium IgA and normal intestinal histology with the presence of human leukocyte antigen class II antigens consistent with the disease were defined as latent celiac disease.
Anti-endomysium IgA was positive in eight diabetic patients, while it was negative in all controls. Celiac disease was found in a total of six (6%) patients, four with manifest and two with latent disease. Only one patient had symptoms.
The prevalence of celiac disease is increased in patients with type 1 diabetes mellitus. Since many patients may be asymptomatic, it is suggested that all diabetic patients should be screened for this disease.
