Adherence to Hepatitis C Virus Therapy in HIV/Hepatitis C-Coinfected Patients.
Summary of "Adherence to Hepatitis C Virus Therapy in HIV/Hepatitis C-Coinfected Patients."
Adherence to hepatitis C virus (HCV) therapy has been incompletely examined among HIV-infected patients. We assessed changes in interferon and ribavirin adherence and evaluated the relationship between adherence and early (EVR) and sustained virologic response (SVR). We performed a cohort study among 333 HIV/HCV-coinfected patients who received pegylated interferon and ribavirin between 2001 and 2006 and had HCV RNA before and after treatment. Adherence was calculated over 12-week intervals using pharmacy refills. Mean interferon and ribavirin adherence declined 2.5 and 4.1 percentage points per 12-week interval, respectively. Among genotype 1/4 patients, EVR increased with higher ribavirin adherence, but this association was less strong for interferon. SVR among these patients was higher with increasing interferon and ribavirin adherence over the first, second, and third, but not fourth, 12-week intervals. Among HIV/HCV patients, EVR and SVR increased with higher interferon and ribavirin adherence. Adherence to both antivirals declined over time, but more so for ribavirin.

Medical and Biotech [MESH] Definitions
INFLAMMATION of the LIVER in humans caused by HEPATITIS DELTA VIRUS, a defective RNA virus that can only infect HEPATITIS B patients. For its viral coating, hepatitis delta virus requires the HEPATITIS B SURFACE ANTIGENS produced by these patients. Hepatitis D can occur either concomitantly with (coinfection) or subsequent to (superinfection) hepatitis B infection. Similar to hepatitis B, it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.
A family of hepatotropic DNA viruses which contains double-stranded DNA genomes and causes hepatitis in humans and animals. There are two genera: AVIHEPADNAVIRUS and ORTHOHEPADNAVIRUS. Hepadnaviruses include HEPATITIS B VIRUS, duck hepatitis B virus (HEPATITIS B VIRUS, DUCK), heron hepatitis B virus, ground squirrel hepatitis virus, and woodchuck hepatitis B virus (HEPATITIS B VIRUS, WOODCHUCK).
Hepatitis A Virus
A species in the genus HEPATOVIRUS containing one serotype and two strains: HUMAN HEPATITIS A VIRUS and Simian hepatitis A virus causing hepatitis in humans (HEPATITIS A) and primates, respectively.
Hepatitis Delta Virus
A defective virus, containing particles of RNA nucleoprotein in virion-like form, present in patients with acute hepatitis B and chronic hepatitis. It requires the presence of a hepadnavirus for full replication. This is the lone species in the genus Deltavirus.
INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally, and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.
: A single nucleotide polymorphism (SNP) upstream of the IL28B gene (rs12979860) predicts sustained virological response (SVR) to peginterferon-ribavirin therapy in chronic hepatitis C patients. There...
Polymorphism in tumor necrosis factor-related apoptosis-inducing ligand receptor 1 is associated with poor viral response to interferon-based hepatitis C virus therapy in HIV/hepatitis C virus-coinfected individuals.
OBJECTIVE(S): HIV/hepatitis C virus (HCV) coinfection causes accelerated liver disease compared to HCV monoinfection, and only 30-60% of HIV/HCV-coinfected individuals respond to HCV therapy with pegy...
ABSTRACT: We reported a 23 years old male with chronic hepatitis C virus infection, discontinued from pegylated interferon/ribavirin combination therapy due to a lack of early virological response. He...
Abstract In the United States, approximately 30% of all human immunodeficiency virus (HIV)-positive patients are also infected with hepatitis C virus (HCV). Both viruses share similar routes of transm...
: We hypothesized that hepatitis C virus (HCV) load and genotype may influence all-cause mortality in HIV-HCV-coinfected individuals.
Insulin resistance is common in people coinfected with HIV and Hepatitis C virus (HCV) and is associated with poor responses to treatment for HCV. Pioglitazone is an FDA-approved medicatio...

This study will evaluate the impact of standard hepatitis C virus treatment on brain deficits in people who are infected with both HIV and the hepatitis C virus.
The purpose of this research study is to find out the effect of the investigational drug NOV-205 on the level of hepatitis C virus in the blood and whether NOV-205 is well-tolerated at dif...
