Azithromycin in Bronchiolitis Obliterans Syndrome

Official Title: “Randomized Double-blind Placebo-controlled Prevention Trial of Azithromycin in Lung Transplantation.”

Preventive treatment with azithromycin reduces the prevalence fo Bronchiolitis Obliterans Syndrome after lung transplantation.

- Prospective, interventional, randomized, double-blind, placebo-controlled trial. - Clinical setting (tertiary University Hospital). - Investigator-driven, no pharmaceutical sponsor. - Lung transplant recipients. - Add-on of study-drug (placebo or azithromycin) to 'standard of care' (standardized, routine immunosuppressive and infectious prophylactic protocol). - 1:1 inclusion ratio (placebo:azithromycin). - Randomisation at discharge after informed consent.
