Time to Mycoplasma Pneumoniae RNA Clearance for Wheezy vs. Non-Wheezy Young Children with Community-Acquired Pneumonia.

Abstract:

OBJECTIVES:We sought to investigate the dynamics of Mycoplasma pneumoniae (Mp) RNA in hospitalized young children with community-acquired pneumonia (CAP) and to explore whether Mp RNA clearance differed for wheezy and non-wheezy group after the onset of azithromycin treatment. METHODS:We included hospitalized young children (1-72 months of age) with CAP caused by Mp infection. Mp RNA was detected as soon as the patient was admitted and the dynamics of Mp-RNA were monitored after the beginning of azithromycin treatment on Days 4, 7, 14 and 28. RESULTS:Among 40 hospitalized young children with Mycoplasma pneumoniae pneumonia (Mpp), 16 had wheezing. Time to first positive Mp-RNA confirmation after symptom onset of Mpp was similar for the wheezy group (median 7 days, interquartile range 7-10.5) and the non-wheezy group (median 7 days, interquartile range 5.8-8.3). The duration of positive Mp-RNA detection after the onset of azithromycin treatment was shorter among the wheezy group than in the non-wheezy group (median 4 vs. 7 days; hazard ratio 2.083; 95% confidence interval: 1.023-4.244). CONCLUSIONS:Mp-RNA clearance was significantly faster among Mpp young children with wheezing than in those without wheezing after the onset of azithromycin treatment.Lay summaryWe sought to investigate the dynamics of Mycoplasma pneumoniae (Mp) RNA in hospitalized young children with community-acquired pneumonia and to explore whether Mp RNA clearance differed for wheezy and non-wheezy group after the onset of azithromycin treatment. Our study suggested that Mp-RNA clearance was significantly faster among Mycoplasma pneumoniae pneumonia young children with wheezing than in those without wheezing after the onset of azithromycin treatment.
