Brief Summary:
The objective of this study is to better understand the influence of insulin resistance upon treatment response in hepatitis C virus treated with PEG Intron and Rebetol.

Condition or disease Intervention/treatment Phase
Chronic Hepatitis C Drug: PEG-Intron Plus REBETOL Phase 4

Detailed Description:
The relationship between HCV and IR is an evolving one. This study will allow a more formal evaluation of this relationship. Four hundred patients will be treated using weight based Peg Intron and Rebetol. Clinical and biochemical data related to IR will be collected to determine if any such factors can predict who will have a sustained virological response. To evaluate patients for insulin resistance, the HOMA score (the product of the fasting insulin level and blood glucose level), waist circumference, and body mass index will be measured.

Primary Outcome Measures :
  1. Difference in treatment response rates between those with insulin resistance those without.

Secondary Outcome Measures :
  1. Which marker of Insulin Resistance (i.e. the HOMA score, Waste Circumference or BMI) is the best measure for risk of hypo responsiveness.

  • Any other causes for chronic liver disease other than chronic hepatitis C besides obesity.
  • Hemoglobinopathies (e.g., Thalassemia) or any other cause of hemolytic anemia.
  • Evidence of advanced liver disease such as a history of or presence of ascites, bleeding varices, or hepatic encephalopathy.
  • Preexisting medical condition that could interfere with the patient's participation in the protocol including: CNS trauma or active seizure disorders requiring medication; diabetes mellitus; serious pulmonary disease; immunologically mediated diseases; gout attack within 12 months; or any medical condition requiring, or likely to require during the course of the study, chronic systemic administration of steroids.
  • Patients with evidence of ischemia on stress testing, an arrhythmia, cardiac failure, coronary surgery, uncontrolled hypertension, angina or a myocardial infarction within 12 months.
  • Patients with a history of organ transplantation will be excluded.
  • Patients taking insulin sensitizing drugs.
