Bezlotoxumab in the treatment of Clostridioides difficile infections: a real-life experience.

OBJECTIVE: Following the approval of bezlotoxumab in 2017, studies evaluating its effectiveness in prevention of Clostridioides difficile infection under "real-life" conditions are scarce. METHODS: We conducted a retrospective study developed in a large tertiary care hospital describing the use and outcomes of patients with Clostridioides difficile infection (CDI) treated with bezlotoxumab. RESULTS: A total of 16 patients were include, all of whom had an episode of CDI with high probability of recurrence and 14 of them had some kind of immunosuppression. Bezlotoxumab was effective in the prevention of CDI recurrence in 11 of the 14 cases in which follow up was possible, without significant side effects. CONCLUSIONS: Bezlotoxumab was well tolerated and the incidence of recurrent CDI in a high-risk population for recurrence was only 21.4%.
