Inhaled antibiotics in non-cystic fibrosis bronchiectasis: A meta-analysis.

OBJECTIVE

To evaluate the efficacy and safety of inhaled antibiotics for the treatment of non-cystic fibrosis bronchiectasis (NCFB).

METHODS

Pubmed, Cochrane library, Embase, Elsevier, OVID, Springerlink, Web of knowledge and NEJM were searched for randomized controlled trials (RCTs) on inhaled antibiotics in treatment of NCFB from inception until April 2015. Meta-analysis was conducted to assess the efficacy and safety of inhaled antibiotics in the treatment of NCFB.

RESULTS

Twelve RCTs involving 1154 participants were included. They showed that inhaled antibiotics were more effective in reduction of sputum bacterial density, eradication of P. aeruginosa, prolonged time to exacerbation and reduction of new pathogens emergence with no significant difference in adverse events compared with control groups. However, we did not find significant benefits of inhaled antibiotics in reducing the risk of acute exacerbation, improving health-related quality of life and reduction of P. aeruginosa resistance. Moreover, inhaled antibiotics exerted a statistically significant reduction in FEV1%.

CONCLUSIONS

Inhaled antibiotics may be an alternative pathway to inhibit airway inflammation with no more adverse events in patients with NCFB.
