Abstract
Background The global prevalence of inflammatory bowel disease (IBD) is increasing. However, population-level data are scarce for Asian populations. Aims To outline and compare paediatric and adult IBD incidence and prevalence data in Korea, describe prescription patterns, and analyse outcomes of anti-tumour necrosis factor (anti-TNF) use in a nationally representative cohort. Methods IBD was identified based on the presence of Rare and Intractable Disease diagnosis codes for Crohn's disease (CD) and ulcerative colitis (UC). We calculated age-based prevalence and incidence, and examined prescription patterns. We used Cox proportional hazard model to calculate the hazard ratio (HR) for undergoing surgery. Results The prevalence of CD increased between 2006 and 2015, particularly among teenagers aged 10-19 years (12.7-35.5 patients per 100,000 people). The use of anti-TNF agents increased from 3.2% to 22.9% in paediatric CD patients. Early use of an anti-TNF agent increased 25-fold in CD patients. Further, CD patients aged 0-14 years were most likely to undergo fistulectomy (HR, 2.63; 95% confidence interval [CI], 1.73-3.97). Children with UC had a higher risk of undergoing surgery (HR, 3.01; 95% CI, 1.33-6.83) than adults. Early use of an anti-TNF agent in CD patients was associated with lower odds of surgery than late-stage use. Conclusion These data demonstrate that the prevalence of IBD has increased over time, especially among paediatric patients. Given the magnitude of paediatric IBD disease burden, a multi-faceted approach is needed for early detection and vigilant monitoring to aim for better prognosis.
