The most feared event, acute severe UC, can lead to life-threatening and systemic complications. Little is known about the determinants of severity in UC. The investigators hypothesize that distinct severity phenotypes of UC arise from intricated host-microbiota mechanisms influencing repair mechanisms. Our first and main objective is to study the natural history of UC during a one-year time period in a cohort of patients.",[71,72,73],"Ulcerative Colitis","Inflammatory Bowel Disease (IBD)","Acute Severe Ulcerative Colitis",[75,76,77,78],"Acute severe ulcerative colitis","Ulcerative colitis","Inflammatory bowel disease","Biobank","NOT_YET_RECRUITING","2025-07-21",{"date":82,"type":83},"2025-07-24","ACTUAL",{"date":85,"type":65},"2025-09",{"date":87,"type":65},"2027-09",{"name":5,"class":6},1]
