Abstract

Abstract: The ESCMID-EUCIC guideline on decolonization of multidrug-resistant Gram-negative bacteria carriers does not recommend routine decolonization and highlights the necessity of well-powered and designed randomized clinical trials. Based on this limited evidence, we decided to conduct a scoping review with the aim of describing and discussing the last published studies investigating the efficacy and safety of decolonization therapies in drug-resistant Enterobacteriaceae carriers. Studies published in PubMed from January 1, 2017 to December 28, 2021 were retrieved. A PICO (population, intervention, comparator, outcome) framework was used for article selection as follows: Population defined as any patient of any age in any setting with screening sample yielding for drug-resistant Enterobacteriaceae; Intervention defined as any decolonization; Controls defined as patients receiving no intervention (spontaneous decolonization) or a different decolonization therapy; Outcomes defined as a microbiological, clinical, epidemiological and adverse event. A total of 679 records were initially identified, of which 647 were excluded because they were not related to decolonization therapies. Other 18 records were excluded because not related to our aims, target bacteria, or study design. A total of 12 clinical studies were included, of which 4 were randomized clinical trials and 8 were non-randomized studies. The majority of studies evaluated selective decontamination of the digestive tract or selective oropharyngeal decontamination regimens. Selected studies were characterized by high heterogeneity. Further high-quality studies with proper design and sample size calculation are warranted. Highlights: Decolonization may be an interesting strategy for MDR Gram-negative bacteria. Data on efficacy/safety of decolonization are heterogeneous. The long-term efficacy/safety of decolonization needs to be further evaluated.
