摘要 AIM To examine the incidence and trends in pediatric inflammatory bowel diseases(IBDs) over 2000-2015 and project the incidence to 2018. METHODS A 16-year prospective study of IBD patients < 19 years of age was conducted in the Czech Republic(the Pilsen region). All incident IBD cases within a well-defined geographical area were retrieved from a prospectively collected computerized clinical database. Historical Czech data were used for comparison(1990-2001). Our catchment population was determined from the census data. We calculated the incidence by relating the number of newly diagnosed cases to the size of thepediatric population-at-risk in each calendar year. Age/sex, disease type, place of residence, and race/ethnicity were identified. RESULTS In total, 170 new IBD cases [105 Crohn's disease(CD), 48 ulcerative colitis(UC), and 17 IBD-unclassified(IBD-U)] were identified. The median age at IBD diagnosis was 14.2 years, 59.4% were males, and 97.1% were Caucasians. A male preponderance of IBD(P = 0.026) and CD(P = 0.016) was observed. With 109209 person-years in the catchment area, the average incidence of IBD per 100000 person-years was 10.0(6.2 for CD, 2.8 for UC, and 1.0 for IBD-U) for children aged 0 to 19 years; for those aged 0 to 15 years, the incidence rate was 7.3(4.6 for CD, 2.0 for UC, and 0.7 for IBD-U). An increase in incidence with age was observed(P = 0.0003). Over the 16-year period, the incidence increased for IBD patients(P = 0.01) and CD in particular(P < 0.0001), whereas the incidence for UC(P = 0.09) and IBD-U(P = 0.339) remained unchanged. IBD-projected data from 2016 to 2018 were 12.1, 12.3 and 12.6 per 100000 personyears, respectively.CONCLUSION Pediatric-onset IBD incidence is around its highest point. The increase, which is particularly pronounced for CD, may be challenging to relate to causes of pediatric disease.
