Clostridioides difficileinfections are a growing concern in the hospital setting. Current prevention methods include infection control strategies, antibiotic stewardship, and proper hand hygiene. However, the occurrence ofC. difficilestill manages to cause nosocomial outbreaks especially in vulnerable populations. Probiotics have been historically questioned for their use in the prevention of antibiotic-associated diarrhea and more specifically,C. difficileinfections.This meta-analysis pools 10 randomized controlled trials for the prevention ofClostridioides difficileinfections (CDI) from reviewing the Cochrane Central Register of Controlled Trials (CENTRAL).A prioriinclusion criteria remained as follows: RCTs, blinded/open trials, all populations, articles, or conference abstracts. Exclusion criteria excluded publications published outside 2013-2023*, non-English language trials, pre-clinical trials/protocols, case reports/series/systematic reviews, duplicates, probiotics not specified in methods, non-RCTs, incomplete/no outcomes reported, no confirmation ofClostridioides difficileinfection. Probiotic strains tested in these trials mainly includedLactobacillus spp. and Bifidobacterium spp. Some studies showed significant benefits while others did not find significant improvement in the prevention ofC. difficileinfections.The meta-analysis suggests that probiotics may have a positive effect in preventing CDI during antibiotic treatment. The study results had large levels of statistical heterogeneity which indicates an argument for further large-scale research to provide more definitive evidence on the efficacy of probiotics in CDI prevention.
