Comparison of Deflazacort and Prednisone in Duchenne Muscular Dystrophy

Objective Duchenne muscular dystrophy (DMD) is a degenerative disease that usually becomes clinically detectable in childhood as progressive proximal weakness. No cure is yet available for DMD, but the use of steroids improves muscle strength and function. This study has been carried out to select the best steroid for the management of DMD. Materials & Methods This study is a single-blind, randomized clinical trial with a sample volume of 34 DMD patients. Half of these patients were treated with deflazacort (0.9 mg/ kg daily) and the other half with prednisone (0.75 mg/kg daily) for a period of 18 months. The motor function score and excess body weight were registered one year after the start and also at the end of the study and compared between the two groups. Results Deflazacort was more effective in the improvement of motor function after one year, but there was no significant difference between the two drugs at the end of the study (18 months after start). Weight gain after one year and at the end of the study was higher in prednisone group and steroid treatment with deflazacort appears to cause fewer side effects than prednisone regarding weight gain. Conclusion Deflazacort seems to be more effective than prednisone in the improvement of motor function causing fewer side effects, particularly weight gain. This medication may be important for the improvement of motor function and could be used as the best steroidal treatment for Duchenne muscular dystrophy.
