This study found a high incidence of early-onset IBD and an over-representation of Indian ethnicity among pediatric patients with inflammatory bowel disease in Asia. South Asian CD patients were more likely to have symptomatic perianal disease.
BACKGROUND There remains a dearth of Asian epidemiological literature for paediatric inflammatory bowel disease (PIBD). AIM To describe the presenting features of PIBD from 7 Asia-Pacific pediatric gastroenterology centers via a central standardised electronic data platform. METHODS Clinical, endoscopic and radiologic data at diagnosis from the registry were extracted between 1(st) January 1995 to 31(st) December 2019. Disease phenotypic characteristics were classified as per the Paris classification system. RESULTS There was a distinct rise in new PIBD cases: Nearly half (48.6%) of the cohort was diagnosed in the most recent 5 years (2015-2019). The ratio of Crohn's disease (CD):Ulcerative colitis (UC):IBD-Unclassified was 55.9%:38.3%:5.8%. The mean age was 9.07 years with a high proportion of very early onset IBD (VEO-IBD) (29.3%) and EO-IBD (52.7%). An over-representation of the Indian/South Asian ethnic group was observed which accounted for 37.0% of the overall Singapore/Malaysia subcohort (6.8%-9.0% Indians in census). Indian/South Asian CD patients were also most likely to present with symptomatic perianal disease (P = 0.003). CD patients presented with significantly more constitutional symptoms (fever, anorexia, malaise/fatigue and muscle-wasting) than UC and higher inflammatory indices (higher C-reactive protein and lower albumin levels). CONCLUSION We observed a high incidence of VEO-IBD and an over-representation of the Indian ethnicity. South Asian CD patients were more likely to have symptomatic perianal disease.
