Circulating fibrocytes as biomarkers of impaired lung function in adults with sickle cell disease.

ABSTRACT: Lung injury and fibrosis are common in patients with sickle cell disease (SCD). Fibrocytes, a population of circulating, bone marrow-derived cells, have been linked to development and progression of tissue fibrogenesis and have been implicated in the development of lung fibrosis in preclinical models of SCD. We tested the hypothesis that the levels and activation state of circulating fibrocytes during steady state are associated with abnormal pulmonary function in adults with SCD. In a prospective cohort of steady-state adults with SCD and healthy age- and race-matched control participants, we measured the concentration and activation state of circulating fibrocytes and assessed pulmonary phenotype with pulmonary function tests (PFTs), a respiratory questionnaire, 6-minute walk test, high-
