Abstract:
Recurrent Clostridioides difficile infection remains common despite optimized antibiotic therapy. Two Food and Drug Administration-approved donor-derived fecal microbiota-based products, fecal microbiota, live-jslm (Rebyota / RBL) and fecal microbiota spores, live-brpk (Vowst / VOS) reduce recurrence when administered after completion of standard antibiotics. This review summarizes the clinical development programs supporting these products, including pivotal randomized trials, open-label extensions, durability data, safety outcomes, and emerging real-world evidence. We also discuss patient selection, timing after antibiotics, diagnostic considerations, and practical implementation. These therapies represent standardized, evidence-based approaches to restoring colonization resistance and preventing recurrent infection in appropriately selected adults.

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
