Asthma and chronic sickle cell lung disease: a dynamic relationship

Abstract

Chronic lung disease is a significant source of morbidity and mortality in patients with sickle cell disease. Asthma and sickle cell lung disease share many of the same clinical features and pathophysiological mechanisms. Though there is growing evidence of an association between sickle cell disease and airway hyper-reactivity, there is still no consensus on the definition of asthma in sickle cell lung disease. This review will explore what we know about asthma and airway hyper-reactivity in sickle cell disease and whether currently available asthma therapies may be beneficial in delaying or averting the progression of sickle cell lung disease.
