BACKGROUND Effective treatment for hepatitis C virus (HCV) in patients coinfected with human immunodeficiency virus type 1 (HIV-1) remains an unmet medical need. METHODS We conducted a multicenter, single-group, open-label study involving patients coinfected with HIV-1 and genotype 1 or 4 HCV receiving an antiretroviral regimen of tenofovir and emtricitabine with efavirenz, rilpivirine, or ra...
Background Clinical response to highly active antiretroviral therapy (HAART) varies among different populations. A portion of this variability may be due to variation in genes involved in the absorption, distribution, metabolism, and excretion (ADME) of HAART. Design To identify genetic factors involved in virologic responses to HAART, 13 genes in ADME pathways were analyzed in a cohort of HI...
HIV-infected pregnant women with undetectable plasma HIV RNA concentrations at delivery pose a minimal risk of vertical transmission. We studied the kinetics and the determinants of the virologic response to antiretroviral therapy in 117 consecutive pregnancies. Patients who initiated therapy during pregnancy had a VL decrease of 2 and 2.5 log(10) after 4 and 24 weeks, respectively. Therapeutic...
BACKGROUND/AIMS Combined treatment of pegylated interferon-α (PEG-IFN) and ribavirin (RBV) has long been accepted as the standard treatment for chronic hepatitis C virus (HCV) infection. Many predictive factors for treatment response have been identified. The aim of this study was to evaluate the efficacy and safety of combined PEG-IFN plus RBV and to examine the value of serum uric acid as a p...
Rapid virologic response (RVR) and complete early virologic response (cEVR) are associated with sustained virologic response to hepatitis C virus (HCV) therapy. We retrospectively examined baseline and on-treatment factors associated with RVR (HCV RNA undetectable at week 4) and cEVR (HCV RNA undetectable at week 12, regardless of week 4 response). The analysis comprised 1550 HCV genotype-1 pat...
BACKGROUND Chronic hepatitis C virus (HCV) infection is a cause of major complications in persons who are also infected with the human immunodeficiency virus (HIV). However, the treatment of HCV infection in such persons has been associated with a high rate of intolerance and a low rate of response. We conducted a multicenter, randomized trial comparing peginterferon plus ribavirin with interfe...
BACKGROUND Peginterferon (PEG-IFN) α-2a has been shown to induce a sustained virologic response (SVR) in 20-30% of "hepatitis B e antigen (HBeAg)"-negative patients. AIM To determine the safety and efficacy of PEG-IFN α-2a in HBeAg-negative, genotype D-naive patients and to analyze the predictors of response. METHODS This prospective, multicenter, open-label, nonrandomized trial was conduct...
CD4 T lymphocyte proliferative responses to hepatitis C virus (HCV) antigens were evaluated before and during an anti-HCV regimen (interferon-alpha2a and ribavirin) in 36 patients coinfected with HCV and human immunodeficiency virus (HIV), to determine whether immune responses against HCV antigens are present in such patients, whether these responses are modified by anti-HCV treatment, and whet...
BACKGROUND Among patients with hepatitis C virus (HCV) monoinfection, 25-hydroxyvitamin D [25(OH)D] concentrations are positively associated with a response to peg-interferon/ribavirin. Data on the relation between 25(OH)D concentrations and HCV treatment response in HIV-infected patients are limited. OBJECTIVE The objective was to determine whether baseline 25(OH)D concentrations predict vir...
