A corticosteroid with mixed glucocorticoid-mineralocorticoid actions was previously shown to improve neuromuscular function in muscular dystrophic chickens. The significance of that finding was recently underscored by reports that a mixed-action corticosteroid improved muscle function in Duchenne dystrophy patients, albeit at high doses. In the present study a pure glucocorticoid improved function and retarded muscle histopathology in the chicken, but a pure mineralocorticoid did not. These observations suggest that elucidation of mechanisms by which glucocorticoids beneficially affect dystrophic muscle could lead to development of more effective therapies.
