Intravenous steroids were less effective in ulcerative colitis patients with older-onset disease, compared with younger-onset patients, according to data from nearly 500 individuals.
A combination of rising ulcerative colitis rates and an aging population has driven an increase in older-onset UC worldwide, Shinji Okabayashi, MD, of Kyoto University, and colleagues wrote in a study published in Alimentary Pharmacology & Therapeutics.
Data on differences in disease history between younger- and older-onset cases have been inconsistent, but one meta-analysis suggested a higher rate of surgery in older-onset cases, the authors of the current study wrote. "The higher risk of surgery may be due to the difference in effectiveness of intravenous steroid treatment, which is one of the important treatment options to avoid surgery for a severe course of UC," but data on the effectiveness of IV steroids for older-onset UC are lacking.
The researchers reviewed data from 467 adults with ulcerative colitis at 27 centers in Japan. The participants were hospitalized and received their initial intravenous steroids between April 2014 and July 2019. The treatment was a daily dose of 40 mg or more of IV prednisoloneor its equivalent, with dosing according to current guidelines. The primary outcome was clinical remission after 30 days.
