Abstract
We assessed prophylactic use of bisphosphonate (BP) in Duchenne muscular dystrophy (DMD) patients on glucocorticoid (GC) therapy. Fifty-two DMD patients on daily GC were offered BP (oral risedronate). Patients were reviewed for tolerability, side effects, bone pain, and fracture frequency. Bone mineral density (BMD) was determined by annual dual energy X-ray absorptiometry. BP-treated patients were compared with 15 BP-naïve patients (untreated cohort). Side effects occurred in 9 patients. Thirty-six patients continued BP therapy for over 12 months (mean, 3.6 years). Five treated patients reported bone pain. Three treated patients suffered a vertebral fracture, significantly less than in the untreated cohort (5/15). Lumbar spine adjusted BMD Z-scores remained unchanged in treated patients and were significantly greater than in the untreated cohort. Prophylactic oral risedronate therapy was tolerated by most DMD patients. It appears to maintain BMD and may reduce fracture rate in DMD patients on GC. Muscle Nerve 54: 79-85, 2016.
