Long-Term Azithromycin for Bronchiolitis Obliterans Syndrome After Lung Transplantation

Abstract

Azithromycin can improve airflow limitation in a significant proportion of patients with even long-standing BOS. The majority of responders were identified after 3 months of treatment. Results indicate the predictive value of BAL neutrophilia for treatment response and pretreatment course of FEV1 as a variable for disease progression. Beneficial effects on gastroesophageal reflux disease may be a mechanism of action.
