Long-Term Steroid Therapy in Duchenne Muscular Dystrophy-Positive Results versus Side Effects.
OBJECTIVE
In tins retrospective study, positive results and side effects of long-term steroid treatment for Duchenne muscular dystrophy were analyzed. Results of an average follow-up period of 65 months (range, 49-79 mo) are described.


METHODS
Nineteen male patients receiving steroids (0.9 mg/kg deflazacort) were compared with the natural history of Duchenne muscular dystrophy given in the literature. Additionally, 13 of these 19 patients were compared with an age-matched control group of 13 patients with Duchenne muscular dystrophy who were not receiving steroid treatment. They were not treated because of loss of independent walking before their first examination in our department or after informed consent with the parents. The same investigators followed all patients.


RESULTS
Muscle strength, functional grade according to Vignos scale, and timed functional tests were significantly better in patients on steroids. The vital capacity was significantly improved in treated versus untreated boys; cardiologic examinations revealed no obvious difference. The main side effects of steroids in patients with Duchenne muscular dystrophy were obesity (2 of 13), cataracts (6 of 13), and short stature (II of 13). Rates of infectious diseases or of bone fractures resulting from osteoporosis were not increased.


CONCLUSIONS
Long-term steroid treatment in Duchenne muscular dystrophy (average. 65 mo) proved beneficial m terms of muscle strength, function, and tolerable side effects, as compared with untreated patients with Duchenne muscular dystrophy.
