  3. Documentation of hepatitis C infection by demonstration of a positive test for hepatitis C antibody and HCV RNA level of 2000 copies/mL or greater.
  4. Histopathologic features consistent with chronic hepatitis C at the time of enrollment. A liver biopsy done for a subject within 24 months prior to his or her participation may be used as the baseline biopsy.
  5. Patients infected with genotype 1.
  6. Patients with CD4+ cell counts greater than 100 cells/mm(3).
  7. Ability to sign the Informed Consent document, and willingness to comply with the study requirements and clinic policies.
  8. Neutrophil count greater than 1000 cells/mm(3).
  9. Platelets greater than 75,000/mm(3).
  10. Hemoglobin greater than 10.5 g/dL.
  11. ALT less than 7 times the NIH upper limit of normal.
  12. Serum lipase less than 1.5 times the NIH upper limit of normal.
  13. Not pregnant or breast-feeding.
  14. If the patient is able to become pregnant, then she must use two effective methods of contraception during the study. Effective contraceptive methods include abstinence, surgical sterilization of either partner, barrier methods such as diaphragm, condom, cap, or sponge, or use of hormonal contraception with an anti-HIV regimen that will not alter metabolism of hormonal contraception. This is advised on the basis of using ribavirin, which may have a potential teratogenic effect on the fetus in pregnant women.
  15. Willingness to not become pregnant until 7 months after completion of ribavirin therapy.
  16. Male subjects who are not documented to be sterile agree to either abstain from intercourse or consistently and correctly use a condom while their female partner (if applicable) agrees to use one of the appropriate medically accepted methods of birth control listed above from the date of screening until 7 months after their last dose of ribavirin.
  17. Patients with a documented addiction are currently in an addiction-free period for at least 6 months and in the clinical judgment of the investigator are not at risk of relapse.
  18. Opioid-dependent patients are in a supervised methadone treatment program.
  19. Need to have a primary doctor outside of OP8 or as part of the OP8 training clinic who will be taking care of the patients for their HIV infection and liver disease.
  20. Willing to designate a person for durable power of attorney on the NIH form for medical research and medical care purposes at the NIH Clinical Center.
  21. Able to learn to safely inject medication Alb-IFN subcutaneously or be able to find another person or a clinic to inject the medication for him/her.
  22. Willingness to abstain from alcohol use during the trial.
  23. Willingness to allow stored blood or tissue samples to be used in the future for studying HIV disease and immune function.
  24. Willingness to permit HLA typing to be performed.

EXCLUSION CRITERIA:

1. Patient cannot be on other experimental therapies (including expanded access/compassionate use of antiretrovirals) during his/her participation in this protocol.
2. Patients cannot have used interferon or peginterferon previously for the treatment of hepatitis C.
3. Mixed genotypes (e.g., 1/2, 1/4). Mixed genotype 1a/1b will be enrolled.
4. Liver histology which, in the opinion of Clinical Center pathologist, is consistent with any other co-existent cause of chronic liver disease as defined as: chronic hepatitis B with positive HBsAg autoimmune hepatitis with a positive ANA greater than 1 unit or positive anti mitochondrial antibody greater than 1 unit; cholestatic disease with persistent elevation of alkaline phosphatase; primary biliary cirrhosis or sclerosing cholangitis; Wilson's disease; alpha-1-antitrypsin deficiency; steatohepatitis (alcoholic or non alcoholic) with marked steatosis, many Mallory bodies, or extensive zone 3 periportal fibrosis.
5. Hemochromatosis or secondary iron overload as defined by (1) an elevated serum ferritin or an iron saturation (serum iron/IBC times 100%) of greater than 50%, and (2) presence of 3+ or more stainable iron on liver biopsy according to the study pathologist. Those subjects with, or a history of previous phlebotomy for iron overload will undergo HFE genetic counseling and those with a positive HFE genetic test demonstrating homozygosity for C282Y and H63D are not eligible. Those who have compound heterozygosity to C282Y and H63D are also not eligible.

7. PT-INR greater than 2 or history of hemophilia or known history of Vitamin K deficiency or use of anticoagulants.
8. Organ transplant recipient other than cornea or hair transplant.
9. Estimated Creatinine clearance (eGFR) less than 50 mL/min.
10. A serum alpha-fetoprotein level (greater than 20 ng/mL, unless the subject has a negative ultrasound before enrollment.
