Abstract
There is limited data on Vedolizumab utilization in elderly patients. Our study aims to assess the effectiveness and safety of Vedolizumab in this subset population.
Databases including Cochrane Central, Embase, Medline (via Ovid), Scopus, and Web of Science were searched in August 2022 to identify studies that assessed Vedolizumab therapy in elderly patients. Pooled proportion and risk ratios (RR) were calculated.
Total 11 studies with 3546 IBD patients (1314 elderly and 2232 young) were included in the final analysis. Pooled rate of overall and serious infections in the elderly cohort was 8.45% (95% CI=6.27-11.29; I223%) and 2.59% (95% CI=0.78-8.29; I276%), respectively. However, there was no difference in overall infection rates between elderly and young patients. Pooled rate of endoscopic, clinical, and steroid-free remission for elderly IBD patients was 38.45% (95% CI=20.74-59.56; I293%), 37.95% (95% CI=33.08-43.06; I213%), and 38.8% (95% CI=31.6-46.4; I277%), respectively. Elderly patients had lower steroid-free remission rates [RR 0.85, 95% CI=0.74-0.99; I20%, P=0.03]; however, there was no difference in rates of clinical (RR 0.86, 95% CI=0.72-1.03; I20%, P=0.10) or endoscopic remission (RR 1.06, 95% CI=0.83-1.35; I20%, P=0.63) compared with younger patients. Pooled rate of IBD-related surgery and IBD-related hospitalizations was 9.76% (95% CI=5.81-15.92; I278%) and 10.54% (95% CI=8.37-13.2; I20%), respectively for the elderly cohort. There was no statistical difference in IBD-related surgeries between elderly and young IBD patients, RR 1.20 (95% CI=0.79-1.84; I216%), P=0.4.
Vedolizumab is equally safe and effective for clinical and endoscopic remission in elderly and younger populations.
