ABSTRACT
OBJECTIVE: To evaluate the efficacy and safety of azithromycin in eradicating Ureaplasma and preventing bronchopulmonary dysplasia (BPD) in preterm infants.
DESIGN: Six literature databases and three clinical trial registration platforms were searched for studies up to 22 July 2024. The meta-analysis was performed using RevMan V.5.3.
RESULTS: A total of 1723 preterm infants from 10 randomised controlled trials and 3 case series were included. In all preterm infants, azithromycin significantly improved Ureaplasma clearance (relative risk (RR)=1.47, 95% CI 1.17 to 1.85) and reduced the duration of mechanical ventilation (mean difference (MD)=-2.16, 95% CI -2.65 to -1.68), duration of supplemental oxygen (MD=-5.46, 95% CI -6.65 to -4.37) and length of stay (MD=-4.98, 95% CI -7.19 to -2.76) compared with placebo; however, there was no significant reduction in BPD, BPD-death or mortality, with low quality of evidence. In Ureaplasma-positive preterm infants, azithromycin significantly reduced BPD-death (RR=0.83, 95% CI 0.70 to 0.99) and mechanical ventilation (MD=-2.20, 95% CI -2.72 to -1.69), compared with placebo, and significantly increased Ureaplasma clearance rate. Additionally, compared with erythromycin, azithromycin reduced BPD, without a statistically significant difference. Compared with placebo, azithromycin showed no statistically significant differences in the incidence of necrotising enterocolitis, retinopathy, intraventricular haemorrhage, etc. CONCLUSIONS: Low-quality evidence indicated prophylactic use of azithromycin could reduce the incidence of BPD-death and the duration of mechanical ventilation in Ureaplasma-positive preterm infants. However, such benefits were not observed in all preterm infants. Meanwhile, azithromycin was found to be safe for administration in preterm infants.
