Abstract

Fecal microbiota transplantation (FMT) is a widely accepted alternative therapy for Clostridioides difficile infection and other gastrointestinal disorders. Thorough donor screening is required as a safety control measure to minimize transmission of infectious agents in FMT. We report the donor screening process and outcomes at a fecal microbiota bank in Korea. From August 2017 to June 2020, the qualification of 62 individuals as FMT donors was evaluated using clinical assessment and laboratory tests. Forty-six (74%) candidates were excluded after clinical assessment; high body mass index (>25) was the most common reason for exclusion, followed by atopy, asthma, and allergy history. Four of the remaining 16 (25%) candidates failed to meet laboratory test criteria, resulting in a 19% qualification rate. FMT donor re-qualification was conducted monthly as an additional safety control measure, and only three (5%) candidates were eligible for repeated donation. As high prevalence of multidrug-resistant organisms (55%) and Helicobacter pylori (44%) were detected in qualified donors during the screening, a urea breath test was added to the existing protocol. The present results emphasize the importance of implementing a donor re-qualification system to minimize risk factors not identified during initial donor screening.
