RESUMO
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.

Vedolizumab is used in the treatment of inflammatory bowel disease and is generally well tolerated. We report a 20-year-old man who presented with right flank pain on a background of ulcerative colitis. He was on vedolizumab with his last dose 1 week before the onset of symptoms. Kidney function tests revealed a serum creatinine of 171 µmoL/L and a C-reactive protein of 74 mg/L. Kidney biopsy demonstrated focal acute interstitial nephritis. He was prescribed oral prednisolone and achieved complete recovery of renal function within 3 weeks. At the follow-up after 4 months, his renal function remains normal.
RESUMO
Culture-independent molecular techniques have demonstrated that the majority of the gut microbiota is uncultivable. Application of these molecular techniques to more accurately identify the indigenous gut microbiome has moved with great pace over recent years, leading to a substantial increase in understanding of gut microbial communities in both health and a number of disorders, including irritable bowel syndrome (IBS). Use of culture-independent molecular techniques already employed to characterise faecal and, to a lesser extent, colonic mucosal microbial populations in IBS, without reliance on insensitive, traditional microbiological culture techniques, has the potential to more accurately determine microbial composition in the small intestine of patients with this disorder, at least that occurring proximally and within reach of sampling. Current data concerning culture-based and culture-independent analyses of the small intestinal microbiome in IBS are considered here.
