ABSTRACT
BACKGROUND:
Doxycycline (DX) is the first-line therapeutic agent for scrub typhus. Macrolides, especially azithromycin (AZ), have been found to be equally efficacious as DX for treating scrub typhus in adults. We conducted this study to compare the efficacy of AZ versus DX in pediatric scrub typhus. STUDYDESIGN:
Open-label randomized controlled trial.METHODS:
Children 1-14 years of age suffering from acute febrile illness of ≥5 days and with a positive scrub IgM serology were randomized to receive either DX (2.2 mg/kg/dose twice daily in <40 kg; 100 mg BD in >40 kg for 7 days) or AZ (10 mg/kg/day for 5 days). The primary outcome was defervescence within 7 days of DX or 5 days of AZ.RESULTS:
We had 75 children randomized and analyzed using an intention-to-treat approach and 60 children analyzed via per-protocol analysis. The proportion of children achieving defervescence was comparable in 2 groups [per-protocolanalysis:
90.9% in the DX group vs. 96.3% in the AZ group, RR 0.94 (95% CI 0.83-1.08)]. On Kaplan-Meier curves, AZ showed a significantly higher probability of defervescence at any time point during treatment as compared with DX (log-rank test P value 0.035).CONCLUSION:
AZ and DX had comparable rates of defervescence among children with scrub typhus. Trial registration No. CTRI/2020/01/022991.
