autoimmunity and viral infections are closely associated fields, and viruses have been proposed as a likely aetiological, contributory or triggering factors of systemic autoimmune diseases. hepatitis c virus seems to be the virus usually associated with the appearance of autoimmune diseases, and the relationship between chronic hepatitis c virus infection and some autoimmune disease has been st...

context hepatitis b and hepatitis c (hbv and hcv) infections are both major causes of hepatocellular carcinoma (hcc). however, hcc caused by each of these two viruses has unique characteristics that should be studied independently to that of another one. while hbv- and hcv-related hccs share similar host and environmental risk factors such as male gender, age above 50 years old, family history ...

Literature review shows that hepatitis C infection may increase the risk of non-hodgkin lymphoma. Reactivation of hepatitis B infection has been reported in patients with hairy cell leukemia after chemotherapy and/or splenectomy. We present hepatitis B surface (HBs) antigenemia and concurrent hepatitis C virus (HCV) seropositivity in a case of hairy cell leukemia. Key Words: Hairy cell leukemi...

objectives: patients with hepatitis c virus infection are at high risk of getting hepatitis a virus. hepatitis a virus is an important widespread virus that usually causes more severe medical consequences in patients with chronic liver disease. the purpose of this study was to evaluate prevalence of hepatitis a virus antibody in patients with chronic hcv in isfahan province, iran. methods: a cr...

Abstract Background: Distribution of hepatitis C virus genotypes varies geographically and can be associated with clinical aspects. The virus has six major genotypes and eleven sub-genotypes. According to the recent studies, in hepatitis C patients, treatment duration and ribavirin dosage should be determined based on the type of virus genotype. Be...

conclusions health care providers need to pay special attention to sexual transmission of hcv among hiv-infected individuals, and should recommend control/preventive measures for hcv sexual transmission. results age of the index samples was 38.71 ± 7 years, and 33.2 ± 6.3 for their main heterosexual partners; the mean duration of sexual relationship for couples was 11.9 (median = 8.5) years. mu...

Background and Aims: Viral hepatitis is a global health problem with a high mortality rate. Recently, a new Flavi-like virus, provisionally named hepatitis G virus (HGV), has been described. HGV does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (...

conclusions the majority of hiv-infected persons in the city of kashan were also hcv positive. genotype 1 was the predominant type, alongside subtype a. considering the high prevalence of hcv among the hiv-infected persons, as well as the impact of occupation, education, illicit drug use, and imprisonment on the incidence of both infections, health policy makers must introduce health programs a...
