Efficacy and Safety of Antibiotics for Treatment of Scrub Typhus: A Network Meta-analysis
Abstract
Importance: Antibiotics have been used for many years to treat scrub typhus, but their efficacy and safety have not been studied thoroughly.
Objective: To compare and rank different antibiotics to identify which one can safely eliminate Orientia tsutsugamushi and efficiently alleviate fever in patients with scrub typhus.
Data sources: An electronic search of PubMed and Embase was conducted, from database inception to July 12, 2019. The study was conducted from July 12 to September 2, 2019.
Study selection: Randomized clinical trials and retrospective studies that evaluated the use of antibiotics for treatment in patients diagnosed with scrub typhus caused by O tsutsugamushi were included. Records of articles in English were considered eligible. Studies were assessed independently by 2 reviewers, with disagreement resolved by consensus. Of 6408 studies initially identified, 10 randomized clinical trials and 4 retrospective study met the criteria for further analysis.
Data extraction and synthesis: This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension statement for systematic reviews incorporating network meta-analyses of health care interventions. Data were independently extracted by 2 reviewers and synthesized with frequentist random-effects network meta-analyses.
Main outcomes and measures: The primary outcome was efficacy of the antibiotic, considered as the number of patients who achieved complete healing with an antibiotic.…
