Washed microbiota transplantation for ribotype 027 Clostridioides difficile infection in a pregnant woman with two-year follow-up: a case report.

Abstract

Clostridioides difficile ( C. difficile) is one of the major causes of nosocomial infections. The pregnant women, who were considered at low risk for C. difficile infection (CDI), have attracted attention with increasing reports. Oral vancomycin, the only first-line treatment for the pregnant women infected with C. difficile, came with the problem of increasing strains resistance that was associated with decreased efficacy. Fecal microbiota transplantation (FMT) is recommended for severe, fulminant and recurrent CDI, while it is avoided in the pregnant women due to safety concerns. We reported a pregnant woman case with primary ribotype 027 CDI, who got a successful outcome with washed microbiota transplantation (WMT), an improved FMT, via enema. The specific strain of ribotype 027 was related to severe outcomes but was not reported in the pregnant women. The follow-up lasted two years, the patient's diarrhea was fully alleviated without recurrence. The baby had normal growth and development and no adverse events were recorded in both of them. This case provides evidence for the efficacy and safety of WMT in the pregnant women infected with C. difficile, indicating that WMT via enema may be a strategy for this population in treating CDI.
