Glucocorticoid Induced Whole Body Catabolisme
- Conditions
- Whole Body Catabolisme Induced by Glucocorticoids
- Interventions
- Drug: Calcium SupplementDrug: Glucocorticoids
- Registration Number
- NCT01762540
- Lead Sponsor
- University of Aarhus
- Brief Summary
The main purpose of the trial is to advance our knowledge on the possible mechanism underlying the catabolic effects of long-term treatment with glucocorticoid.
- Detailed Description
Long-term treatment with glucocorticoid induces a general state of catabolism and increases insulin resistance. The underlying mechanisms are insufficiently characterized, however glucocorticoid induced changes of Growth Hormone (GH) and the Insulin-like growth factor I (IGF-I) appear to be of outmost importance.
We wish to investigate the mechanism behind glucocorticoid induced catabolism and insulin resistance.
More specific we wish to investigate:
* Whether glucocorticoid induces IGF-I inhibiting substances in serum or interstitial fluid that block the ability of IGF-I to phosphorylate its receptor in vitro
* Whether glucocorticoid inhibits intracellular IGF-I and insulin signaling in vitro and in vivo
* The mechanisms by which growth hormone counteracts the CG-mediated inhibition of IGF-I action
