Background And Aims:
Acute severe ulcerative colitis (UC) (ASUC) requiring hospitalization affects up to 1 in 4 patients with UC. There is a paucity of prospective and multicenter clinical cohorts to study treatment trends and predictors of disease outcomes. Here, we conduct a US-based multicenter prospective clinical cohort of ASUC to study predictors of the need for medical rescue therapy and colectomy.
Methods:
A total of 94 patients hospitalized for ASUC were included across 5 academic centers from December 2018 to December 2021. Demographic, clinical, and laboratory data were collected throughout the hospitalization. Patients were followed up to 1-year post-hospitalization to identify predictors of the need for rescue therapy and colectomy.
Results:
A total of 21 (22.3%) patients required colectomy within 1 year of admission with 11 (12%) requiring colectomy during the index admission. On multivariate analyses, a BMI < 21.5 kg/m2 (OR = 6.16, P = .02), a simple clinical colitis activity index (SCCAI) greater than 8 (OR = 14.44, P = .01) and an albumin level at admission lower than 2.4 g/dL (OR = 10.61, P = .04) were significant predictors of inpatient colectomy after adjusting for sex, age, and duration of disease.
Conclusions:
In a prospective, multicenter cohort of patients hospitalized with ASUC, BMI, SCCAI, and albumin at admission were important determinants of colectomy risk during the index hospitalization and within 1 year of admission. Colectomy rates remain high-22.3% in this cohort across 5 academic, tertiary care centers-underscoring the need to identify the highest-risk patients, establish novel treatment and care paradigms, and examine opportunities to standardize care.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
