This study evaluated the therapeutic efficacy and safety of washed microbiota transplantation (WMT) for recurrent Clostridioides difficile infection (CDI). The results showed that 90.7% of CDI patients achieved clinical cure after WMT treatment. WMT may be particularly recommended for patients with severe conditions or complex comorbidities.
Objectives: Fecal microbiota transplantation (FMT) has been recommended for the treatment of recurrent Clostridioides difficile infection (CDI). We aimed to evaluate the therapeutic efficacy and safety of washed microbiota transplantation (WMT), a new method of FMT, for CDI across various medical settings.Methods: This multicenter real-world cohort study included CDI patients undergoing WMT. The primary outcome was the clinical cure rate of CDI within 8 weeks after WMT. Secondary outcomes included the CDI recurrence rate and reduction in total abdominal symptom score (TASS) during the follow-up period. Adverse events related to WMT were recorded.Results: Altogether 90.7% (49/54) of CDI patients achieved clinical cure after treated with WMT. The cure rate was 83.3% for cases with severe and complicated CDI (ScCDI) (n = 30) and 100% for non-ScCDI cases (n = 24) (P = 0.059). No difference was observed in the clinical cure rate between patients with first and recurrent CDI (91.9% vs 88.2%, P = 0.645). One week post-WMT, TASS showed a remarkable decrease compared to that at baseline (P < 0.001). Totally, 8.2% (4/49) of patients suffered CDI recurrence during the follow-up period. A WHO performance score of 4, age >= 65 years, higher TASS score, and higher Charlson comorbidity index score were potential risk factors for efficacy (P = 0.018, 0.03, 0.01, 0.034, respectively). Four (3.8%) transient adverse events related to WMT were observed.Conclusions: This study emphasizes the attractive value of WMT for CDI. Early WMT may be recommended for CDI, especially for those in serious condition or with complex comorbidities.
