Echinocandins versus non-echinocandins for the treatment of invasive candidiasis: A meta-analysis of randomized controlled trials

Introduction: Echinocandins are frequent use antifungals in the treatment of invasive candidiasis, and it is important to update information on their efficacy and safety for optimal antifungal drug treatment. The aim of this study is to clarify whether echinocandins are superior to non-echinocandins for the treatment of invasive candidiasis. Methods: We conducted a meta-analysis of RCTs of echinocandins and non-echinocandins for adult invasive candidiasis. The MEDLINE, Web of Sciences, Cochrane Register of Controlled Trials, and ClinicalTrials.gov databases before June 2019 were used. The risk ratio (RR) and 95% confidence interval (95% CI) were calculated using the Mantel-Haenszel method random-effects model. Results: We identified 14,846 articles and screened, and five studies were included meta-analysis. The treatment success ratio for echinocandins was significantly higher than that for non-echinocandins (RR = 1.14, 95% CI 1.06-1.22, p = 0.0003). In regard to adverse events, there was no significant difference between the two treatment groups. A subgroup analysis showed that the treatment success ratio for echinocandins was significantly higher than that for azoles (RR = 1.20, 1.08-1.34, p = 0.001), whereas no significant differences were observed between echinocandins and polyenes. In safety analysis, the incidence ratio of electrolyte disorder (RR = 0.50, 0.33-0.76, p = 0.001), renal disorder (RR = 0.19, 0.09 -0.40, p < 0.0001), and fever (RR = 0.46, 0.23-0.93, p = 0.03) were significantly lower in patients receiving echinocandins than in those receiving polyenes. Conclusions: This meta-analysis based on RCTs was first to show that use of echinocandins was associated with improved clinical success. Echinocandins may be useful as a first-line drug for invasive candidiasis. (C) 2020 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases. Published by Elsevier Ltd.
