TNF inhibitors have improved treatment options for patients with inflammatory bowel disease (IBD) and three TNF inhibitors, infliximab, adalimumab and golimumab are available for treatment of ulcerative colitis in Switzerland. However, these drugs have been tested under ideal conditions in randomized controlled trials. Real-world data are needed to complement this information. It is the aim of the investigators to study, whether patients with ulcerative colitis can be effectively treated with golimumab in a real world setting in Switzerland.||The investigators used data from the Swiss IBD cohort study (SIBDC) in Switzerland and identified all SIBDC patients with UC treated with Golimumab and performed a retrospective chart review. The investigators acquired patient reported outcomes and objective measures for inflammation at baseline, at 6-10 weeks and at 6 and 12 months after golimumab treatment. Primary endpoint was clinical response (i.e. meaningful improvement) at 6-10 weeks. Secondary endpoints were clinical response at 6 and 12 months and clinical remission (i.e. free of symptoms of disease).
