A Multicenter Prospective Cohort Study on the Clinical Prognosis of Ulcerative Colitis
Mucosal healing or histological remission is an important target for the treatment of inflammatory bowel disease. In this study, patients with mucosal healing are defined as a control group, observing their clinical outcomes for 3 years, and describing the recurrence rate. The secondary objective is to study the operative rate, glucocorticoid utilization rate, treatment escalation rate, hospitalization rate and incidence of related complications.
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
