||Participants With Viral Decline at Day 3 & 28 With Predictors of Post Treatment Response [ Time Frame: Day 3 and Day 28 ] [ Designated as safety issue: No ]
HCV viral kinetics were used to predict rates of sustained virology response (SVR) in HIV/HCV connected subjects.
Measure was determined by analyzing the population of participants with virologic decline of more than 1.0 log at day 3 combined with viral load of less than 5.0 log IU/ml at day 28 to predict sustained virology response

|Brief Title ICMJE||Peginterferon Alpha-2b And Ribavirin to Treat Hepatitis C in HIV-Infected Patients|
|Official Title ICMJE||A Non-Randomized, Open Label, Study to Assess Hepatitis C Viral Kinetics in Predicting the Clinical Response in Patients With Hepatitis C Infection Coinfected With HIV-1 Treated With Peginterferon Alpha-2b and Ribavirin|
This study will evaluate the safety and effectiveness of combination therapy with peginterferon alfa-2b and ribavirin for treating hepatitis C virus (HCV) infection in HIV-infected patients. In studies of patients with hepatitis C alone, interferon alfa-2b plus ribavirin treatment eradicated the HCV in almost half the patients. Peginterferon alfa-2b is a compound that results from attaching a polyethylene glycol molecule to interferon alfa-2b. This compound stays in the blood longer than unmodified interferon alfa-2b, causing a higher blood concentration and thus maintaining activity against the hepatitis C virus.
HIV-infected patients 21 years of age and older with chronic hepatitis C infection and a viral load greater than 2000 copies/mL may be eligible for this 2 1/2-year study. Candidates will be screened with blood and urine tests and possibly a liver biopsy, if a recent one is not available. The liver biopsy is done to determine the severity of liver disease. For this test, patients are admitted to the NIH Clinical Center for 1 to 2 days. A sedative is injected into an arm vein, the skin in the area over the biopsy site is numbed with a local anesthetic, and a needle is inserted rapidly into and out of the liver to obtain a small tissue sample. The patient remains in the hospital overnight for monitoring. A chest X-ray, electrocardiogram (EKG) and liver ultrasound are also done. Within 4 weeks of the screening tests, candidates who appear eligible for the study will have a physical examination, medical history and repeat blood tests. Women who can become pregnant will have serial pregnancy tests throughout the study.
Patients who meet the study criteria and decide to participate will begin treatment with weekly injections under the skin of peginterferon alfa-2b and take ribavirin pills twice a day by mouth. In addition, patients will continue to take all other medications prescribed by their doctor. Clinic visits will be scheduled as follows:
|Detailed Description||Hepatitis C infection occurs in one-third of all HIV-infected individuals. Liver disease has become more clinically significant among patients coinfected with HIV and HCV. Several studies have shown that coinfected individuals develop earlier and severe liver disease. Interferon with ribavirin has become the therapy of choice among people with non-genotype 1a. This is a pilot study to address the relationship of clinical response to combination therapy to the virologic and immunologic parameters. The study will also address the safety and efficacy of the peginterferon alfa-2b among HIV- infected individuals. The predictive ability of baseline HCV viral load, rate of decline of HCV viral load, HIV viral load and CD4 counts to the clinical response of chronic hepatitis to peginterferon and ribavirin will also be studied. Approximately sixty patients who are infected with both HIV and HCV and also have evidence of fibrosis will receive peginterferon alfa-2b and ribavirin for 48 weeks. In order to enroll sixty patients for this study, we will be screening a total of 180 patients. During the 72 weeks study these patients will be monitored for HCV viral load, and other HIV viral load and CD4 counts. Viral kinetics will also be monitored closely and the slope of second, slower phase decline of HCV viral load, which corresponds to the rate of infected cell death presumably may lead to sustained hepatitis C virologic response. The results of the study will enable us to better delineate the possible predictors of sustained response to peginterferon and ribavirin. The safety and tolerability of a combination therapy with peginterferon and ribavirin among HIV-infected individuals on antiretroviral therapy will further define the standard therapy of chronic hepatitis C in HIV-infected individuals.|

|Eligibility Criteria ICMJE||
Age greater than or equal to 18 years.
Documentation of HIV-1 infection by any licensed ELISA test and confirmed by a Western Blot.
Documentation of Hepatitis C infection by demonstration of a positive test for hepatitis C antibody.
HCV RNA level greater than 2000 IU/ml by bDNA.
Infected with HCV genotype 1.
Histopathologic features consistent with chronic hepatitis C on liver biopsy at the time of enrollment.
Patients with CD4 greater than 300 cells/mm(3).
Ability to sign informed consent and willingness to comply with the study requirements and clinic policies.
Serum creatinine less than 1.5 mg/dL.
Serum phosphorus greater than or equal to 2.2 mg/dL (normal range NIH 2.3-4.3 mg/dL).

If capable of pregnancy: use of effective contraception during study: effective contraception 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 OP8 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.
