Hepatitis C virus (HCV) is a global health care problem. Diagnosis of HCV infection is mainly based on the detection of anti-HCV antibodies as a screening test with serum samples. Recombinant immunoblot assays are used as supplemental tests and for the final detection and quantification of HCV RNA in confirmatory tests. In this study, we aimed to compare the HCV core antigen test with the HCV R...

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...

Human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection is characterized by higher serum HCV RNA loads compared with HCV mono-infection. However, the relationship between HIV and HCV replication remains to be clarified. HIV Vpr has been shown to play an essential role in HIV replication. In this study, we aimed to explore the role of Vpr in HCV replication and pathogenesis. We t...

V léčbě infekce virem lidské imunodeficience (HIV) bylo již před delší dobou dosaženo několika zlomových momentů, které vedly k významnému zlepšení prognózy HIV pozitivních pacientů, a zároveň tak umožnily soustředit pozornost na faktory mortality nesouvisející primárně s HIV. Ukázalo se, že zásadní roli zde hraje mortalita hepatální, zejména onemocnění způ...

Background: High-risk behaviors in people with severe mental illnesses, such drug injection by shared equipment and unprotected sex, expose them to the risk of blood-borne infections as hepatitis B virus (HBV) C (HCV) infections. Objectives: This study aimed determine prevalence HBV HCV serum markers illnesses Tehran, Iran. Methods: In this cross-sectional study, schizophrenia, bipolar disorder...

The viral load of different hepatitis C virus (HCV) subtypes, including the globally distributed HCV-1b and the unique Indonesian subtype HCV-1c, was analyzed using serum samples obtained from Indonesian blood donors and patients with chronic liver disease. The mean viral load of HCV-1c was comparable with that of HCV-1b, suggesting that HCV-1c is as pathogenic as HCV-1b. On the other hand, the...

results of 45 patients, 4 (8.9% [95% ci: 4.4-15.6]) had detectable genomic hcv-rna in their pbmc specimens. hcv genotypes were determined in the pbmcs of these subjects showed that 2 (50.0%) subjects with occult hcv infection had hcv subtype 3a, and 2 (50.0%) had hcv subtype 1b. conclusions this study found that 8.9 % of the iranian candidates for liver transplant with cryptogenic cirrhosis had...

BACKGROUND Hepatitis C viral (HCV) load detection and quantification is routinely accomplished by HCV RNA measurement, an expensive but essential test, both for the diagnosis and treatment of chronic hepatitis C (CHC). HCV core antigen (Ag) testing has been suggested as an attractive alternative to molecular diagnostics. The aim of the study was to evaluate an automated chemiluminescent immunoa...

BACKGROUND During HCV infection, the activation status of peripheral blood monocytes and its impact on HCV replication are poorly understood. We hypothesized that a modified activation of peripheral blood monocytes in HIV-HCV coinfected compared to HCV monoinfected patients may contribute to different monocytes reservoirs of HCV replication. METHODS We performed a case-control analysis involv...
