Abstract
Inflammatory bowel disease (IBD) had been uncommon in China until about 1990, but since then, it has been seen in the clinical setting more and more. The prevalence and phenotype of IBD in the Chinese population is not well known. The present study investigates the trend of prevalence in ulcerative colitis (UC) and Crohn's disease (CD) in Wuhan City, central China, and evaluates clinical features, extraintestinal manifestations, and the treatment of IBD in the last 14 years. Three hundred and eighty-nine patients with UC and 63 patients with CD were retrospectively collected from 5 central hospitals in Wuhan City, in which high-quality endoscopic and histological diagnoses were available from 1990 to 2003. UC and CD were diagnosed based on clinical, experimental, radiological, endoscopic, and histological examinations according to the internationally accepted Lennard-Jones criteria. The trend toward prevalence of UC and CD increased between 1990 and 2003 in Wuhan City. There was no change in the sex and age distribution comparing 1990 to 1996 with 1997 to 2003 both in UC and CD. However, the number of individuals with higher education and a professional occupation during 1997 to 2003 was significantly higher than that during the period 1990 to 1996 in patients with UC (OR 2.1, 95% CI 1.27-3.35, P = 0.004; OR 2.2, 95% CI 1.31-3.61, P = 0.003). The mean age of patients with CD was significantly younger than that of UC at the time of diagnosis (32.6 ± 12.5 vs. 42 ± 14.5, P < 0.0001). The ratio of male to female patients was 1.53:1 in UC and 2.32:1 in CD, respectively. The mean duration of onset of the disease to diagnosis was 1.4 years in UC and 1.1 years in CD. The extra intestinal manifestations of UC and CD were 5.7% and 19%, respectively, and complications of UC and CD were 6.4% and 50.8%, respectively. Only 3% of UC patients required surgery, whereas 27% of CD patients underwent surgical procedures (P < 0.001). The prevalence of IBD has increased in Wuhan City, central China, but is not as high as in Western countries. The disease in Wuhan City has often been associated with young adult professional males with a high level of education. The clinical presentation of UC was often mild and had few extra intestinal manifestations.Keywords
