Nine children with Duchenne muscular dystrophy were given Sanorex (mazindol), a growth hormone inhibitor, daily for 6 months. There was no significant change in their muscle function, but there was a significant reduction in weight gain and in levels of growth hormone, somatomedin C, hair zinc, serum zinc, and serum LDH. Selenium and glutathione peroxidase in the serum increased significantly. Thirteen other children with growth hormone deficiency had a significant reduction in hair selenium following growth hormone administration. These results show a significant relationship between growth hormone and selenium nutritional status and confirm our previous reports indicating an effect of growth hormone on zinc nutritional status. It is possible that prolonged therapy with a growth hormone inhibitor would attenuate the course and improve the longevity of patients with muscular dystrophy.

The reduced growth hormone and insulin-like growth factor-I concentrations in growth hormone deficiency and normal ageing are associated with reduced muscle mass and strength, and slower muscle protein synthesis. Recent research has addressed the hypothesis that growth hormone and insulin-like growth factor-I have an anabolic effect in adults, including the elderly. These hormones stimulate whole-body and muscle protein synthesis, at least under some conditions. There is increasing evidence to justify long-term administration of growth hormone to promote muscle growth in growth hormone deficient adults. However, the long-term effects on muscle mass and function in the elderly do not seem beneficial enough to justify widespread hormone replacement therapy. These hormones may be useful anabolic agents to counteract muscle wasting under other conditions, including surgical stress, renal failure, muscular dystrophy, glucocorticoid administration and HIV infection, but more clinical trials are needed to determine the functional significance of the protein anabolic effects under these conditions.
