Fecal Microbiota Transplantation for refractory immune checkpoint inhibitor-associated colitis
Abstract
We report the first case series of immune checkpoint inhibitors (ICI)-associated colitis successfully treated with fecal microbiota transplantation, with reconstitution of the gut microbiome and a relative increase in the proportion of regulatory T-cells within the colonic mucosa. These preliminary data provide evidence that modulation of the gut microbiome may abrogate ICI-associated colitis. Preliminary evidence from two cases suggests that fecal microbiota transplantation may provide a viable treatment option for a severe adverse effect of immune checkpoint blockade therapy in patients with cancer.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
