Abstract

Background: Immunocompromised patients are particularly vulnerable to Clostridioides difficile infection (CDI), hospitalizations and recurrences. Studies have shown that fecal microbiota transplant (FMT) is safe and effective in immunocompromised patients. Aims: To examine the outcomes of FMT for CDI in a diverse cohort of immunocompromised patients stratified by medication class. Methods: We performed a retrospective, long-term follow-up study of FMT in immunocompromised patients, including those undergoing chemotherapy, with inflammatory bowel disease (IBD) on immunomodulators, prior solid organ transplant on immunosuppressants, on chronic steroids 20 mg/day or higher for a minimum of three months, or HIV positive. Primary outcomes included adjusted primary cure rate within 8 weeks, as well as rates of non-response, recurrences, relapses and adverse events. Secondary outcomes included adjusted overall cure rate. Primary cure rate was defined as patients not requiring repeat CDI treatment within 8 weeks after index FMT, and overall cure rate was defined as resolution of CDI symptoms after index FMT or second FMT. Results: Our cohort included 77 immunosuppressed patients (53.2% female, median age 39.1 years, range 7–95 years). The majority of our cohort were IBD patients on biologics (62.3%). Adjusting for colectomies and deaths, our primary and overall cure rates were 85.1% and 86.5%, respectively. Twelve patients received FMT for severe or fulminant CDI with a 3-month survival rate of 91.7%. 11.7% of patients experienced serious adverse events following FMT. Conclusions: Our study supports the efficacy and safety of FMT in immunocompromised patients, though future research is needed to further ascertain the potential effects of immunosuppression on FMT outcomes.
