Mortality rates of ulcerative colitis (UC) in some hospital series published in the early 1900s. Overall mortality was from 20% to 55% of the patients with UC. The mortality during the first year after acute UC onset was up to 75%. Reported studies were made in tertiary-care referral centers, most likely including only the more severe cases of UC.
