Clinical and demographic comparison of celiac disease diagnosed during adulthood versus childhood and adolescence: A single-center experience

Background and Aim: Celiac disease (CeD) is mainly reported from the northern and western parts of India. In central India, it is believed to be a disease of children, with limited data among adults diagnosed for the first time after the age of 18 years. Hence, we aimed to describe CeD's clinical and demographic features among adults and children/adolescents in central India. Methods: This is a retrospective analysis of a prospectively maintained database of all patients diagnosed for CeD from 2010 to 2019. The disease in adults was confirmed when symptoms developed for the first time after 18 years and had positive anti-transglutaminase antibodies with villous atrophy on duodenal biopsy. It was compared with pediatric patients with CeD diagnosed during the same time period. Results: Of the 170 patients diagnosed with CeD, 118 were adults and 52 were children or adolescents. The mean age of presentation of adult CeD was 37.3 +/- 11.93 years, while in the pediatric and adolescent group it was 9.19 +/- 5.4 years. Classical presentation with chronic, painless, small-bowel-type diarrhea was seen in 44.1% of adults compared to 57.7% in the pediatric age group. Among the adult patients, 55.9% presented with nonclassical symptoms, which included abdominal pain (40.7%) and weight loss (36.4%). The common presenting symptom in children other than diarrhea was weight loss (50%) and abdominal pain (34.6% ). Conclusion: CeD is common in central India, with an increasing number of patients being diagnosed for the first time after 18 years of age and presenting more often with nonclassical symptoms.
