Summary

In this study we plan to demonstrate that ethanol induces skeletal muscle autophagy to degrade MAA adducts.

Detailed Description

Hypothesis: Ethanol mediated modification of skeletal muscle proteins to form MAA adducts that in turn induce skeletal muscle autophagy. Patients with alcoholic steatosis, hepatitis and cirrhosis (n=10 each) will be recruited from the liver transplant nutrition clinic or the hepatology inpatient service and their body composition quantified using anthropometry, bioelectrical impedance analysis, CT image analysis and DEXA if available. Control Subjects. Controls will be recruited by advertisement. All control subjects will have a normal clinical history, physical examination, and screening chemistries. They will not have any significant medical conditions requiring the use of medications. Their nutritional status within 20% of normal as defined by ideal body weight.
