Abstract
OBJECTIVE
To evaluate the prevalence of beta-cell autoimmunity and the usefulness of a type 1 diabetes screening in patients with celiac disease.
RESEARCH DESIGN AND METHODS
We measured GAD antibodies (GADAs), insulinoma-associated protein 2 antigens (IA-2As), and insulin autoantibodies (IAAs) in 188 young Italian patients with celiac disease (66 male [35.1%]). Mean age at celiac disease diagnosis was 5.4 years (0.5-17.1), and mean celiac disease duration was 4.2 years (0-28.8). Celiac disease was diagnosed by jejunal biopsy after positivity for endomysial and tissue transglutaminase antibody was confirmed.
RESULTS
GADAs were positive in seven patients (3.7%), and IA-2As were positive in two patients. IAAs were negative in all cases. Metabolic evaluation was normal, and no patients developed diabetes during follow-up. There was no significant association among beta-cell autoimmunity and sex, age, pubertal stage, family history, or coexistence of other autoimmune disorders; compliance to a gluten-free diet was confirmed.
CONCLUSIONS
Our results showed a low prevalence of beta-cell autoimmunity and do not support a precocious screening for beta-cell autoimmunity in young celiac disease patients.
