UNLABELLED: The prevalence of celiac disease is higher in children with type 1 diabetes mellitus (DM) than in the general pediatric population, but may vary widely across countries. Sensitive and specific antibody tests are available for detecting celiac disease. AIMS: To evaluate the prevalence in France of histologically documented celiac disease in a vast cohort of children with type 1 DM, and to describe the features of celiac disease and treatment response. METHODS: Retrospective cohort study of 950 children with type 1 diabetes seen between 1994 and 2001. Antibodies to gliadin, reticulin, endomysium and transglutaminase were looked for one to seven times in each patient. RESULTS: Fifteen patients (1.6%) had biopsy-confirmed celiac disease. Symptoms led to the diagnosis in six patients (mean age, 7 years) and screening tests in nine patients (mean age, 11 years). Anti-endomysium antibodies were consistently positive. Tests for HLA-DQB1 0201 and/or 0302 were positive. Anti-endomysium antibody seroconversion was seen in two patients, 2 and 6 years, respectively, after the diagnosis of diabetes. In another patient, the biopsy became abnormal 6 years after the first positive anti-endomysium antibody test (latent form). After a mean of 3 years on a gluten-free diet, significant increases were noted in body weight (P=0.04) and insulin dose (P=0.05); clinical symptoms completely resolved in five of the six symptomatic patients. CONCLUSIONS: The prevalence of celiac disease is higher in children with type 1 DM than in the general pediatric population. Serological screening is useful for diagnosing asymptomatic celiac disease, detecting seroconversion and monitoring latent forms of disease.
