Screening for Celiac Disease in a Pediatric Primary Care Setting.

Celiac disease (CD) is an autoimmune enteropathy in genetically predisposed individuals triggered by the ingestion of gluten. The prevalence in adults in the United States is increasing. Despite recognition of asymptomatic patients that benefit from screening and improved diagnostics, the majority of patients remain undiagnosed. The purpose of this study is to determine the prevalence of CD in at-risk and not-at-risk pediatric patients in a primary care practice routinely screening for CD. The records of 2325 pediatric patients who underwent serological testing with immunoglobulin A tissue transglutaminase (tTG) during a 5-year period were reviewed. Patients were categorized as at-risk or not-at-risk for CD. The prevalence of CD in at-risk patients was 1:26, the prevalence of CD in not-at-risk patients was 1:111. Our results suggest that the prevalence of CD in children approximates that of US adults and that the true prevalence in children without known risk factors may be increasing.
