Background: Ulcerative proctitis, one of the disease types of ulcerative colitis, is considered one of the initial manifestations of ulcerative colitis. Prevention of aggravation of ulcerative proctitis is important for improving the prognosis of ulcerative colitis. Here we reviewed the epidemiology, diagnosis, and management of ulcerative proctitis. Summary: The number of patients with ulcerative proctitis is increasing. Disease extension occurs in many patients with ulcerative proctitis. Differential diagnosis from other chronic proctitis is important and should be performed based on the clinical history and endoscopical and histological features. Mesalazine suppository has been the first-line therapy for patients with ulcerative proctitis because of its high effectiveness and safety. Topical treatment of ulcerative proctitis, particularly using mesalazine suppository has been underused in clinical practice. Key Messages: Mesalazine suppositories are more effective than dose intensification of oral mesalazine for relapsed patients with maintenance dose of oral mesalazine. However, low adherence to rectal mesalazine has hindered remission in patients with ulcerative proctitis.
Background/AimsThe influences of Helicobacter pylori eradication therapy on the disease course of inflammatory bowel disease (IBD) are still unclear. We therefore conducted a multicenter, retrospective cohort study to evaluate the safety of H. pylori eradication therapy for IBD patients.MethodsIBD patients with H. pylori eradication from 2005 to 2015 (eradication group) and control patients (non-eradication group; 2 paired IBD patients without H. pylori eradication matched with each eradicated patient) were included. IBD exacerbation (increased/additional IBD drug or IBD-associated hospitalization/surgery) and disease improvement based on the physicians’ global assessment were investigated at baseline, and at 2 and 6 months after eradication or observation.ResultsA total of 429 IBD (378 ulcerative colitis, 51 Crohn’s disease) patients, comprising 144 patients in the eradication group and 285 patients in the non-eradication group, were enrolled at 25 institutions. IBD exacerbation was comparable between groups (eradication group: 8.3% at 2 months [odds ratio, 1.76; 95% confidence interval, 0.78–3.92; P=0.170], 11.8% at 6 months [odds ratio, 1.60; 95% confidence interval, 0.81–3.11; P=0.172]). Based on the physicians’ global assessment at 2 months, none of the patients in the eradication group improved, whereas 3.2% of the patients in the non-eradication group improved (P=0.019). Multivariate analysis revealed that active disease at baseline, but not H. pylori eradication, was an independent factor for IBD exacerbation during 2 months’ observation period. The overall eradication rate was 84.0%–comparable to previous reports in non-IBD patients.ConclusionsH. pylori eradication therapy does not alter the short-term disease activity of IBD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
