Abstract
Introduction: Recurrent Clostridioides difficile infection (rCDI) is common, with symptoms ranging from diarrhea to life-threatening sepsis. This study aimed to assess the real-world outcomes of patients with rCDI in the United States (US) who received fecal microbiota, live-jslm (RBL), the first US Food and Drug Administration-approved microbiota-based therapy for the prevention of rCDI after antibiotic treatment.
Methods: Adults with rCDI who received RBL between July 2023 and August 2024 at home or in a clinic and had ≥ 8 weeks of follow-up or experienced CDI recurrence at any time after RBL administration were included. Treatment success, defined as no CDI recurrence within 8 weeks of RBL, was assessed overall and in subgroups stratified by age, number of prior CDI recurrences, duration of the antibiotic washout period, prior bezlotoxumab use, and RBL administration setting.
Results: Among 196 patients who received RBL, 176 had either ≥ 8 weeks of follow-up or had < 8 weeks of follow-up but experienced CDI recurrence during that period. The treatment success rate at 8 weeks was 83.0%. No significant differences were observed in treatment success rates among subgroups based on age (< 65 years old vs. ≥ 65 years old: 85.9% vs. 80.2%, p = 0.20), duration of the antibiotic washout period (24 h: 80.0%, 48 h: 84.5%, 72 h: 85.0%, p = 0.68), number of prior CDI recurrences (< 3 vs. ≥ 3: 82.5% vs. 83.1%, p = 0.60), or prior bezlotoxumab use (86.4% vs. 83.7%, p = 1.00). Patients receiving RBL at home had a higher treatment success rate compared to those receiving RBL in a clinic (87.3% vs. 62.5%, p < 0.01).
Conclusions: RBL was highly effective in preventing rCDI in a real-world setting, including at-home administration. The effectiveness was also observed among high-risk subgroups, such as patients ≥ 65 years old and those with ≥ 3 prior CDI recurrences.
期刊介绍：
Infectious Diseases and Therapy is an international, open access, peer-reviewed, rapid publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of infectious disease therapies and interventions, including vaccines and devices. Studies relating to diagnostic products and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to, bacterial and fungal infections, viral infections (including HIV/AIDS and hepatitis), parasitological diseases, tuberculosis and other mycobacterial diseases, vaccinations and other interventions, and drug-resistance, chronic infections, epidemiology and tropical, emergent, pediatric, dermal and sexually-transmitted diseases.
