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: * Days 1, 3, 5, 7, 10 and 21 - Blood will be drawn for safety tests and to measure blood levels of HIV and HCV. * Weeks 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 52, 56 and 64 - Blood and urine tests will be done to determine the side effects of treatment and its effect on the HCV infection. * Week 48 or end of treatment - Treatment will stop after 48 weeks. At this time, or earlier for those who do not complete the 48 weeks, patients will return to the clinic for a routine test.
This study will evaluate the safety and effectiveness of adding the experimental drug adefovir dipivoxil to lamivudine for treating hepatitis B virus (HBV) infection in HIV-infected patients with liver cirrhosis. Adefovir inhibits HBV by interfering with replication of the virus's genetic material. In some people, the drug has been active against strains of HBV that are resistant to lamivudine; it may also have some activity against HIV. HIV-infected patients 21 years of age and older with chronic hepatitis B infection and liver cirrhosis who have received lamivudine treatment for at least 1 year may be eligible for this 48-week study. Candidates will be screened with a complete medical history, blood tests and a 24-hour urine collection. Blood tests include HLA typing (a test of genetic markers on white blood cells that permit specialized immunology studies). Within 4 weeks, candidates who appear eligible for the study will have a physical examination and medical history, an abdominal ultrasound (imaging test using sound waves) to check for cancer of the liver, chest X-ray and electrocardiogram (EKG). Blood and urine tests will also be done, and women who can become pregnant will have a pregnancy test. Patients who meet the study criteria and decide to participate will then start treatment with one 10-mg adefovir pill per day by mouth. In addition, patients will continue to take all other medications prescribed by their doctor. Follow-up clinic visits will be scheduled as follows: * Days 1, 3, 5, 7, 10 and 21 - Blood will be drawn for specialized immunology tests and to measure blood levels of HIV and HBV. * Weeks 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44 - Blood and urine (single sample) tests will be done to determine the side effects of adefovir and its effect on the HBV infection. * Week 48 or early termination (end of study) - Blood tests (including tests for hepatitis C and D), abdominal ultrasound and a 24-hour urine collection to evaluate kidney function will be done. * Monthly visits beyond week 48 - Based on the HBV response to treatment and the availability of the drug from the sponsor, patients may be offered to extend their treatment with adefovir. Those who continue will have monthly follow-up visits for blood and urine (single sample) tests.
