PURPOSE: This study aims to evaluate the effects of azithromycin on lung function in children with cystic fibrosis (CF) through a systematic review and meta-analysis of randomized controlled trials (RCTs). The study primarily focuses on its impact on FEV1 (forced expiratory volume in 1 second), FVC (forced vital capacity), and the progression of lung function decline.
METHODS: Electronic searches were conducted across PubMed,Cochrane Central, Embase, Web of Science, and China National Knowledge Infrastructure databases, including studies published up to November 1, 2024. Inclusion criteria required RCTs involving children with CF, azithromycin as the intervention, and placebo controls. Meta-analyses were performed using random-effects models, and heterogeneity was assessed using the I² statistic. Sensitivity analyses were conducted to ensure the robustness of results.
FINDINGS: Eight RCTs were included, covering a total of 625 participants. Meta-analysis revealed that azithromycin significantly improved FEV1 compared to the control group, with a standardized mean difference (SMD) of 0.58 (95% CI: 0.03-1.14), though substantial heterogeneity was observed (I² = 82.8%). However, no statistically significant improvement in FVC was detected (SMD: 0.62, 95% CI: -0.04 to 1.29, I² = 85.4%). Additionally, azithromycin reduced the relative risk of lung function decline (RR: 0.79, 95% CI: 0.62-1.00), with moderate heterogeneity (I² = 45.5%). Sensitivity analyses confirmed the stability of these results.
IMPLICATIONS: Azithromycin shows potential in improving FEV1 and slowing lung function decline in children with cystic fibrosis, likely through its anti-inflammatory and immunomodulatory effects. Further large-scale studies are warranted to confirm its long-term efficacy, evaluate safety, and optimize treatment strategies, including potential combination therapies.
