Sickle cell anemia (SCA) is a life-threatening, monogenic disorder associated with early death when compared to individuals without SCA. Pulmonary complications, namely acute chest syndrome, obstructive lung disease and pulmonary hypertension, are the most common causes of death in patients with SCA. Recent studies suggest that lung specific inflammation is a hallmark of SCA and underlies pulmonary pathology. To date, no therapy has been shown to improve the pulmonary complications of SCA. Macrolides have pleomorphic effects in the lung with improvement in pulmonary function, symptoms and inflammatory markers demonstrated in several inflammatory pulmonary conditions such as cystic fibrosis, asthma, COPD and post-transplant bronchiolitis obliterans. Investigators hypothesize that low dose macrolide therapy is well tolerated and can improve pulmonary function and symptoms in patients with SCA. The objective of this project is to assess the feasibility of macrolides to attenuate or reverse the decrease in %predicted FEV1 in adults with SCA in a single-site, randomized, placebo-controlled feasibility trial.
