A Pilot Trial of Prednisone in Facioscapulohumeral Muscular Dystrophy
1997
Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant, 4q35-linked, slowly progressive muscular dystrophy with no known effective treatment. Since prednisone improves strength in Duchenne dystrophy, we performed a pilot, open-label trial of prednisone in eight subjects fulfilling strict diagnostic criteria for FSHD. Prednisone (1.5 mg/kg/day; maximum 80 mg/day) was administered for 12 weeks. Manual muscle testing, maximum voluntary isometric contraction testing, and muscle mass estimations by dual energy x-ray absorptiometry and urinary creatinine excretion were performed at baseline and at 12 weeks. There were no significant changes in strength or muscle mass. We conclude that prednisone given for 12 weeks does not produce major improvement in strength or increase muscle mass in FSHD. The study did not have sufficient power or length of follow-up to address the possibility that prednisone might arrest or slow disease progression. NEUROLOGY 1997;48: 46-49
