Use of a ghrelin agonist to improve the catabolic effects of glucocorticoid treatment
A method and pharmaceutical composition for inhibiting the effect of glucocorticoids, particularly dexamethasone, which suppress growth hormone secretion, by administering ghrelin or a ghrelin analogue, for example, H-Inp-D-Bal-D-Trp-Phe-Apc-NH 2 (SEQ ID NO:73) or other suitable ghrelin agonist, to counteract the catabolic effects of dexamethasone and other natural glucocorticoids.
1. A method to ameliorate the catabolic effects of excess glucocorticoids in an individual in need of such treatment comprising administering to said individual a therapeutically effective amount of a non-native ghrelin agonist, wherein said non-native ghrelin agonist is H-Inp-D-Bal-D-Trp-Phe-Apc-NH 2 (SEQ ID NO:73), and wherein said excess glucocorticoids are the result of the long term administration of dexamethasone to said individual.
2. A method according to claim 1 , wherein said glucocorticoid induced catabolic effects are selected from the group consisting of reduction in growth, reduction in growth rate, reduction in body weight, reduction in lean body mass, reduction in IGF-1 levels and reduction in bone mass.
3. A method according to claim 2 , wherein said amelioration alleviates the reduction in growth in an individual with excess glucocorticoids.
4. A method according to claim 2 , wherein said amelioration alleviates the reduction in growth rate in an individual with excess glucocorticoids.
5. A method according to claim 2 , wherein said amelioration alleviates the reduction in body weight in said individual with excess glucocorticoids.
6. A method according to claim 2 , wherein said reduction in body weight is due in part to a loss in lean body mass.
7. A method according to claim 2 , wherein said amelioration alleviates the reduction in IGF-1 levels in said individual with excess glucocorticoids.
8. A method according to claim 2 , wherein said amelioration alleviates the reduction in bone mass in said individual with excess glucocorticoids.
9. A method for allowing the long term administration of therapeutic doses of glucocorticoids to treat a disease or condition, comprising alleviating the catabolic effects of the administration of said long term therapeutic doses of glucocorticoids by the administration of a non-native ghrelin agonist to an individual, wherein said non-native ghrelin agonist is H-Inp-D-Bal-D-Trp-Phe-Apc-NH 2 (SEQ ID NO:73), and wherein said administered glucocorticoid is dexamethasone.
10. A method according to claim 9 , wherein said therapeutic doses of glucocorticoids are administered to an individual to treat asthma and said catabolic effects of said long term administration of therapeutic doses of glucocorticoids are alleviated by the administration of a non-native ghrelin agonist.
