Epidemiology of Inflammatory Bowel Disease in the Songpa-Kangdong District, Seoul, Korea.
The purpose of this study is to evaluate the incidence, prevalence, clinical characteristics and prognosis of Crohn's disease and ulcerative colitis over time in a district of Seoul, Korea.
|Study Design:||Observational Model: Cohort|
|Official Title:||Epidemiology of Inflammatory Bowel Disease in the Songpa-Kangdong District, Seoul, Korea.|
- Incidence rate and prevalence rate of IBD [ Time Frame: 1986-2017 (up to 31 years) ] [ Designated as safety issue: No ]
- Annual incidence rate of Crohn's disease and ulcerative colitis
- Prevalence rate of Crohn's disease and ulcerative colitis as of Dec 31, 2017.
- Clinical features of patients with IBD [ Time Frame: 1986-2017 (up to 31 years) ] [ Designated as safety issue: No ]
- Clinical characteristics of patients newly diagnosed with Crohn's disease or ulcerative colitis: gender, presenting symptoms, duration between symptoms to diagnosis, and phenotypes, etc.
- Clinical course of patients newly diagnosed with Crohn's disease or ulcerative colitis: development of complications (strictures, perforations), intestinal resection rate, hospitalization rate, mortality, and pregnancies and their outcomes
- Treatment modalities of IBD and their trends: use of medication (5-ASA, corticosteroids, immunomodulators, and biologic agents, etc.)

The Songpa-Kangdong cohort of IBD
Incident cases of IBD in the Songpa-Kangdong district, a well-defined administrative area in Seoul, the capital of Korea, beginning in 1986, when the first patient with IBD was diagnosed, until 2017. For the prevalent cases, the inhabitants with IBD at Dec 31, 2007 in the Songpa-Kangdong district are included.
Inflammatory bowel disease (IBD), which is comprised of Crohn's disease (CD) and ulcerative colitis (UC) is a chronic inflammatory disease of gut with uncertain etiopathogenesis. According to our previous study (Yang, et al. Inflamm Bowel Dis 2008; 14: 542-549), the incidence and prevalence of IBD in Korea are still low compared with those in Western countries, but are rapidly increasing. However, the long-term trends of epidemiology of CD and UC together with their characteristics and prognosis in Korea are uncertain yet. The investigators therefore aim to elucidate the incidence and prevalence of CD and UC over a 30-year period, from 1986 to 2017, in the Songpa-Kangdong district of Seoul, Korea. In addition, the investigators also aim to reveal the clinical features at the time of diagnosis of IBD, long-term evolution of disease and prognosis.
