We defined multidrug-resistant organisms as vancomycin-resistant Enterococcus faecium (VREfm), and multidrug-resistant Gram-negative Enterobacterales. Methods: We searched the EMBASE, Cochrane Central, and PubMed databases from inception to medio November 2023. We included randomised and controlled clinical trials (RCTs), that investigated the effect of antibiotics on the eradication of multidrug-resistant organisms in intestinal carriers. Finally, we performed a meta-analysis. Results: We included five RTCs in the systematic review. In four studies an effect of antibiotics on the eradication of MRO was shown at the end of intervention, but it was not sustained at follow-up. In the fifth study, the effect at the end of intervention was not reported, and there was no observed effect of the intervention at follow-up. We included four studies in the meta-analysis, and it suggests an effect of antibiotics on the eradication of MRO in intestinal carriers at the end of follow-up with a p-value of 0.04 (95% confidence interval 1.02\u20131.95). None of the studies reported a significant increase in resistance to the study drug. Gastrointestinal disorders were the most frequent non-severe adverse event. Conclusions: The effect of antibiotics on the eradication of multidrug-resistant organisms in intestinal carriers was not statistically significant in any of the five included studies; however, we found a significant effect in the pooled meta-analysis. As the confidence interval is large, we cannot determine the clinical importance of this finding, and it should be further investigated.<\/jats:p>","DOI":"10.3390\/antibiotics13080747","type":"journal-article","created":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T09:48:54Z","timestamp":1723196934000},"page":"747","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Effect of Antibiotics on the Eradication of Multidrug-Resistant Organisms in Intestinal Carriers\u2014A Systematic Review with Meta-Analysis"],"prefix":"10.3390","volume":"13","author":[{"given":"Maja Johanne S\u00f8ndergaard","family":"Knudsen","sequence":"first","affiliation":[{"name":"Department of Clinical Microbiology, Copenhagen University Hospital\u2013Amager and Hvidovre, 2650 Hvidovre, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6158-2927","authenticated-orcid":false,"given":"Ingrid Maria Cecilia","family":"Rubin","sequence":"additional","affiliation":[{"name":"Department of Clinical Microbiology, Copenhagen University Hospital\u2013Amager and Hvidovre, 2650 Hvidovre, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0531-0553","authenticated-orcid":false,"given":"Andreas Munk","family":"Petersen","sequence":"additional","affiliation":[{"name":"Department of Clinical Microbiology, Copenhagen University Hospital\u2013Amager and Hvidovre, 2650 Hvidovre, Denmark"},{"name":"Gastrounit, Medical Section, Copenhagen University Hospital-Amager and Hvidovre, 2650 Hvidovre, Denmark"},{"name":"Department of Clinical Medicine, University of Copenhagen, 2200 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1712","DOI":"10.1093\/jac\/dkaa074","article-title":"Association between vancomycin-resistant Enterococcus faecium colonization and subsequent infection: A retrospective WGS study","volume":"75","author":"Rubin","year":"2020","journal-title":"J.
