We describe changes in pulmonary function measures across time in Duchenne muscular dystrophy patients treated with glucocorticoids (GCs) > 1 year compared to GC naïve patients in the Cooperative International Research Group Duchenne Natural History Study, a multicenter prospective cohort study. 397 participants underwent 2799 pulmonary function assessments over a period up to 10 years. Fifty-three GC naïve participants ( 1 year cumulative GC treatment. Forced vital capacity (FVC), peak expiratory flow rate (PEFr), maximal inspiratory and expiratory pressures were performed and calculated as a percent predicted (%p). GC treatment slowed the rate of pulmonary decline as measured by FVC%p, in ..View full abstract
