Macrolides versus other antibiotics in pediatric scrub typhus: A meta-analysis.

Background: While Doxycycline is the recommended drug for treating scrub typhus, there is a growing trend of using Macrolides and Other antibiotics due to their perceived advantages. In this study, we compared the efficacy of Macrolides versus Other antibiotics in the treatment of pediatric scrub typhus.

Methods: Meta-analysis of randomized controlled trials (RCTs) with GRADE (Grading of Recommendations, Assessment, Development and Evaluation) application. Major databases were searched till 30 December 2022. Children of all age groups were included. Primary outcomes included mortality rate and time to defervescence (h).

Results: Of the 103 citations retrieved, 5 trials, including 383 children up to 15 years of age with probable and confirmed cases of scrub typhus, were included. None of the trials reported mortality rate. The pooled results from the trials found no significant difference between Azithromycin and Other antibiotics for any of the outcome measures. The certainty of evidence for the primary outcome was deemed to be of "very low certainty", while the certainty of evidence for the secondary outcomes ranged from "low to moderate certainty".

Conclusions: The current meta-analysis revealed that there was no significant difference between Azithromycin and Other antibiotics (such as Doxycycline and Chloramphenicol) in the treatment of scrub typhus in children. However, it's important to note that the evidence generated for the primary outcome was of "very low certainty".
