Some children with type 1 diabetes mellitus may have or may develop celiac disease. Positive antigliadin antibodies, especially specific antibodies (eg, antiendomysial, antitransglutaminase) are important risk markers. If antibody tests are positive, a jejunal biopsy is required to confirm or refute a diagnosis of celiac disease. Once celiac disease is confirmed, the individual should remain on a gluten-free diet for life.
