Peginterferon Alpha-2a and Ribavirin to Treat Hepatitis C in HIV-infected Patients

INCLUSION CRITERIA

• Age greater than or equal to18 years.
• Documentation of HIV-1 infection by licensed ELISA test and confirmed by a Western Blot.
• Documentation of Hepatitis C infection by demonstration of a positive test for hepatitis C antibody and on HCV RNA level of 2000 or greater.
• Histopathologic features consistent with chronic hepatitis C on liver biopsy at the time of enrollment. A liver biopsy done for a subject within a year prior to his or her participation may be used as the baseline biopsy.
• Patients with CD4+ cell count greater than 200 cells/mm3 or CD4+ cell percentage greater than 14%.
• Ability to sign informed consent and willingness to comply with the study requirements and clinic policies.
• Serum phosphorus greater than or equal to 2.2 mg/dL and less than or equal to 4.4 (normal range NIH 2.3-4.3 mg/dL).
• Neutrophil count greater than or equal to 1000 cells/mm3.
• Platelets greater than or equal to 50,000/ mm3.
• Hemoglobin greater than or equal to 10.5 mg/dL.
• ALT less than 7 X the NIH upper limit of normal.
• Serum lipase less than 1.5 X the NIH upper limit of normal.
• Not pregnant or breast-feeding. Pregnancy test must be negative within two weeks prior to dosing with study medications.
• 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 in pregnant women.
• 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.
• 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.
• Able to learn to safely inject medication subcutaneously or be able to find another person or a clinic to inject for him/her.
