Older adults with acute severe ulcerative colitis have similar steroid non-response and colectomy rates as younger adults

BACKGROUND There is paucity of data on outcomes of acute severe ulcerative colitis (ASUC) in older adults (>= 60 years of age).AIM To assess steroid non-response rates during the index admission for ASUC in older adults. Secondary outcomes were response to medical rescue therapy and colectomy rates; at index admission, 3 and 12 mo.METHODS This retrospective multicentre cohort study included ASUC admissions who received intravenous steroids between January 2013 and July 2020 at two tertiary hospitals. Electronic medical records were reviewed to collect clinical, biochemical, and endoscopic data. A modified Poisson regression model was used for analysis.RESULTS Of 226 ASUC episodes, 45 (19.9%) occurred in patients >= 60 years of age. Steroid non-response rates were comparable in older adults and patients < 60 years of age [19 (42.2%) vs 85 (47%), P = 0.618, crude risk ratio (RR) = 0.89 [95% confidence interval (CI): 0.61-1.30], adjusted RR = 0.99 (0.44-2.21). Rates of response to medical rescue therapy in older adults was comparable to the younger cohort [76.5% vs 85.7%, P = 0.46, crude RR = 0.89 (0.67-1.17)]. Index admission colectomy [13.3% vs 10.5%, P = 0.598, crude RR = 1.27 (0.53-2.99), adjusted RR = 1.43 (0.34-6.06)], colectomy at 3 mo [20% vs 16.6%, P = 0.66, crude RR = 1.18 (0.61-2.3), adjusted RR = 1.31 (0.32-0.53)] and colectomy at 12 mo [20% vs 23.2%, P = 0.682, crude RR = 0.85 (0.45-1.57), adjusted RR = 1.21 (0.29-4.97)], were similar between the two groups.CONCLUSION In older adults with ASUC, the steroid non-response rate, response to medical rescue therapy, and colectomy rate at index admission, 3 and 12 mo is similar to patients less than 60 years of age.

Automated summary

This study aimed to assess the non-response rates to steroids during the index admission for acute severe ulcerative colitis (ASUC) in older adults (>= 60 years of age). The study found that the non-response rates were similar in older adults and patients younger than 60 years of age. Additionally, the response to medical rescue therapy and the colectomy rates were also similar between the two groups.
