BackgroundFecal microbiota transplantation (FMT) could be a novel treatment option for several chronic diseases associated with altered gut microbiota.PurposeTo examine the conduct and reporting of studies assessing FMT.Data SourcesCochrane Central Register of Controlled Trials, PubMed, EMBASE, and Web of Science from inception to 31 January 2017.Study SelectionTwo reviewers independently examined titles and abstracts to identify all English-language reports of human clinical studies assessing the safety or efficacy of FMT.Data ExtractionThree reviewers independently assessed study types and characteristics and the reporting of important methodological components of the FMT intervention.Data SynthesisMost (84%) of the 85 published reports found addressed the use of FMTs for Clostridium difficile infection or inflammatory bowel disease, and most (87%) were non-randomized controlled trials. Important methodological components that were not reported in published studies included the following: eligibility criteria for donors (47%), materials used for collecting stools and the period of collection (96%), methods used for conservation of stools (76%), the amount and type of stools used (for example, fresh or frozen), and duration of stool conservation (67%). Many (58%) did not report an analysis of microbiota composition.LimitationsLack of universal consensus regarding the most important methodological components of FMT and inability to assess the actual conduct of studies and whether the publication process affected the completeness of reporting.ConclusionKey components of FMT interventions, which are necessary to replicate and understand study findings about efficacy and safety, are poorly reported.Primary Funding SourceNo specific funding.
