Does growth hormone-stimulated IGF-1 generation in cirrhosis reflect hepatocellular dysfunction?
Cirrhosis is associated with low IGF-1 levels and an attenuated response to exogenous GH. These findings correlate better with the extent of hepatic dysfunction rather than the presence of portal hypertension or malnutrition.
Our study showed that plasma leptin levels but not %fat are associated with BMD and the presence of vertebral fractures in postmenopausal women, suggesting that circulating leptin might play a physiological role in maintaining bone mass as well as better bone quality.
