Antibiotic resistance rates in Cutibacterium acnes isolated from patients with acne vulgaris: a systematic review and meta-analysis
Abstract
Background: Cutibacterium acnes (C. acnes) is closely related to the pathogenesis of acne, and studies related to the antibiotic resistance rates of C. acnes have been reported worldwide; however, relevant systematic reviews and meta-analyses are still lacking. The aim of this study was to systematically evaluate the resistance in C. acnes to relevant antibiotics, that this information may be used to provide a rational basis for the antibiotic treatment of acne.
Methods: Relevant studies in PubMed, the Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Data were systematically searched from January 1, 2005, to April 1, 2025, and the resistance rates of C. acnes isolates to quinolones, macrolides, tetracyclines, and other relevant antibiotics were collected. The combined resistance rate was calculated via the R language program package 4.3.2, with subgroup analyses based on different years, continents, countries, provinces in China and different drug susceptibility testing methods.
Results: A total of 8,846 studies were systematically retrieved and 23 studies were included, corresponding to 2,046 isolates of C. acnes, which have shown antibiotic resistance rates ranging from high to low: 48.17% (95% CI: 41.16-55.24%) for roxithromycin, 45.64% (95% CI: 20.49-73.22%) for clarithromycin, 43.33% (95% CI: 27.81-60.29%) for azithromycin, 29.20% (95% CI: 22.14-37.43%) for erythromycin, 22.38% (95% CI: 14.69-32.56%) for clindamycin,…
