Identification of prevalent infection by hepatitis C virus (HCV) is based serologically on detecting anti-HCV immunoglobulin G, using immunoassays, immunoblot assays, and, more recently, immunochromatography-based rapid tests. None discriminate between active and resolved HCV infection. Tests for detecting HCV RNA identify active HCV infection but are costly. Serologic assays for HCV antigens h...

Data are limited on the effectiveness and safety of peginterferon plus ribavirin in HIV-infected Asian patients with acute or chronic HCV infection. HIV-infected Taiwanese patients with acute HCV infection received peginterferon plus weight-based ribavirin for 24 weeks (n = 24), and those with chronic HCV genotype 1 or 6 (HCV-1/6) and HCV genotype 2 or 3 (HCV-2/3) infection received response-gu...

Alcohol use disorder (AUD) and hepatitis C virus (HCV) infection frequently co-occur. AUD is associated with greater exposure to HCV infection, increased HCV infection persistence, and more extensive liver damage due to interactions between AUD and HCV on immune responses, cytotoxicity, and oxidative stress. Although AUD and HCV infection are associated with increased morbidity and mortality, H...

Background and Aims: Many studies have provided evidence for the role of hepatitis B and C viruses in the development of liver cancer. Although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with HBV and HCV. This study was performed to determine the frequency of HBV/HCV-coinfection in Mashhad, North-East of Iran. Mat...

chronic hepatitis c might lead to several immunological dysfunctions. studies have shown a positive association between hepatitis c virus (hcv) infection and psoriasis. these results suggest that the infection may be one of the triggering factors for the development or exacerbation of psoriasis. here, we present a case of chronic hcv infection with psoriasis who developed exacerbation of skin l...

Background: Regulatory T cells (Tregs) have been involved in impaired immunity and may have a pivotal role in persistence of viral infections. Objective: To develop a simple and reliable in-house three color flow cytometery of peripheral blood to understand the role of HCV infection in the increase of Tregs. Methods: The level of naturally occurring CD4+CD25+FoxP3+ regulatory T cells (nTregs) i...

Abstract Globally, approximately 1.5 million new Hepatitis C virus (HCV) infections occur annually. A vaccine to prevent chronic HCV infection would limit transmission and pathogenesis of HCV. To understand immunity in high risk populations, we prospectively followed antibody negative high-risk people who inject drugs (PWIDs) a protocol designed for monthly follow-up. We demonstrated previously...

A retrospective cohort study was established of injecting drug users (IDUs) to assess evidence for hepatitis C virus (HCV) protective immunity through a comparison of incidence of initial HCV infection and HCV reinfection. Incidence of initial HCV infection was determined among HCV seronegative IDUs, and HCV reinfection determined among IDUs with newly acquired HCV infection, HCV viraemia and s...

BACKGROUND Chronic hepatitis C virus (HCV) infection causes a substantial health and economic burden in the United States. With the availability of direct-acting antiviral agents, recently approved therapies and those under development, and 1-time birth-cohort screening, the burden of this disease is expected to decrease. OBJECTIVE To predict the effect of new therapies and screening on chron...

Introduction. Several viruses including hepatitis C virus (HCV) and human immunodeficiency (HIV) can induce vasculitis. Aim. We aimed to study the incidence, risk factors, severity of skin vasculitis in patients with HCV HCV/HIV coinfection. Patients Methods. T he group included 331 (254 77 coinfection) referred a specialized hepatology center for antiviral therapy infection. Results. Skin was ...
