Study Details

Study Description

Brief Summary

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

Condition or Disease Intervention/Treatment Phase
  • Other: Biopsies

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.

Arms and Interventions

Arm Intervention/Treatment
Alcoholic Steatosis

This group will have 10 patients with alcoholic steatosis which is milder disease and muscle biopsies will be performed

Other: Biopsies
Biopsy will be done on the Vastus Lateralis muscle in all groups

Cirrhosis

This group will consist of 10 patients with cirrhosis. We anticipate a 50% difference in these patients and the controls in the autophagy readouts and muscle biopsies will be performed

Other: Biopsies
Biopsy will be done on the Vastus Lateralis muscle in all groups

Steatohepatitis

This group will have 10 patients with alcoholic steatohepatitis that have more severe necroinflammation in the liver but for a shorter duration of illness and muscle biopsies will be performed

Other: Biopsies
Biopsy will be done on the Vastus Lateralis muscle in all groups

controls

This group will consist of 10 patients who are healthy and have no liver disease diagnosis and muscle biopsies will be performed

Other: Biopsies
Biopsy will be done on the Vastus Lateralis muscle in all groups

Outcome Measures

Primary Outcome Measures

  1. Skeletal Muscle Autophagy [4 hours]

    We will measure Malonyldialdehyde Acetaldehyde protein adducts to see skeletal muscle proteolysis during a one time muscle biopsy
