The relationship between acute myeloid leukemia (AML), acute lymphocytic leukemia, chronic myeloid leukemia (CML), and refractory anemia with excess of blasts (RAEB) and antibodies to human T-cell lymphotropic virus types I and II (HTLV-I and HTLV-II), and hepatitis B virus and hepatitis C virus (HCV) was investigated in a multicenter case-control study. There were 431 cases enrolled in the stu...

Hepatitis C virus (HCV) is increasingly common among human immunodeficiency virus (HIV)-infected men who have sex with men. We evaluated the efficacy of HCV core antigen in diagnosing acute HCV in an HIV-infected cohort. Compared with HCV polymerase chain reaction, core antigen proved sensitive (100%) and specific (97.9%). As a quick, simple, and cost-effective test, it has considerable utility...

Introduction: Hepatitis D virus (HDV) is a 35 nm in diameter agent that depends on hepatitis B surface antigen in order to proliferate and accumulate. Infection with delta agent can occur spontaneously with hepatitis B virus infection and it cause acute hepatitis or develop as secondary infection in the patients with hepatitis B. Hepatitis D virus (HDV) has several genotypes based on genome seq...

Background: Scleroderma is a chronic systemic disorder that affects the connective tissues. It is characterized by several immune manifestations, inflammation, vascular damage, and fibrosis. Some of the viral infections with complex mechanisms are involved in the development and progression of many autoimmune diseases, such as scleroderma. The present study aimed to investigate the serological ...

â  hepadnaviruses employ an unusual strategy for the production of enormous number of virions during replication which makes rapid and substantial genetic sequence changes and alterations. the pathogenesis and clearance of hepatitis b virus (hbv) infection are engaged by the selection and expression of viral mutants durâ­ing virus-host interactions. mutations in regulatory regions such as the b...

CD4+ Treg-cells (regulatory T-cells) probably contribute to the impaired virus-specific T-cell responses in chronic HCV (hepatitis C virus) infection; however, their antigen-specificity has remained elusive. In the present study, we analysed peripheral blood CD4+ Treg-cells in patients with chronic hepatitis C and subjects with self-limited HCV infection and characterized individual Treg-cell c...

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...
