Study Summary

Obesity is associated with reduced growth hormone (GH) secretion. Reduced GH secretion in obesity is associated with increased cardiovascular disease risk. However, it is not yet known how reduced GH increases cardiovascular disease risk in obesity. The investigators hypothesize that reduced GH contributes to dysfunction of the mitochondria. Therefore, the investigators hypothesize that treatment of obese subjects with reduced GH secretion with GH will improve mitochondrial function and that this improvement in mitochondrial function will contribute, in part, to the effects of GH to improve metabolic parameters in obesity. The investigators propose to study skeletal muscle mitochondria in obese subjects with reduced GH secretion using magnetic resonance spectroscopy and muscle biopsies before and after treatment with GH.

Primary Outcome

The primary objective of this study is to determine the effects of growth hormone on mitochondrial function as assessed by 31P-MRS in obese subjects with reduced GH secretion. Mitochondrial function was represented by ViPCr, a measure of phosphocreatine recovery after sub-maximal exercise. Univariate regression analyses was performed to assess the relationship between the change in skeletal muscle IGF-1 mRNA after 12 weeks treatment with rhGH to change in ViPCr.
