The efficacy and adverse events of delafloxacin for treating acute bacterial skin and skin structure infections: A systematic review and meta-analysis

Abstract

Background: Acute bacterial skin and skin structure infections (ABSSSI) cause significant morbidity and mortality in hospitalized patients and outpatients as well. Newer fluoroquinolones such as delafloxacin might be a useful medication for treating infections of skin caused by gram-positive bacterial species that are resistant. Aims and Objectives: The aim of this study was to evaluate all the literature on delafloxacin in databases and make comparisons of its efficacy with antimicrobial drugs routinely used to treat skin infections. Materials and Methods: A detailed search on different databases was conducted using, Cochrane Central Register of Controlled Trials, PubMed, and Embase. Primary outcome was microbiological cure at the end of the follow-up period. Absence of the signs and symptoms at the termination of the follow-up period and clinical response to medications was regarded as the secondary outcome. Results: The pooled efficacy of delafloxacin was at 80% (95% confidence interval 1.01 [0.97, 1.06]; P = 0.51). No statistically significant difference was found between intravenous delafloxacin and comparator drugs. Conclusion: The effectiveness of delafloxacin was found to be non-inferior to tigecycline and linezolid. Efficacy and pooled cure rate of delafloxacin was also found to be superior to vancomycin.
