The positive rates of hepatitis B surface antigen (HBsAg) and antibody to hepatitis C virus (anti-HCV) were analyzed according to year, sex, age, and serum ALT levels in 1,370 patients with hepatocellular carcinoma (HCC) who visited the Korea Cancer Center Hospital between January 1989 and December 1994. The positive rate of HBsAg was 68.8 to 76.0% per year in patients with HCC, while that of a...
BACKGROUND Hepatitis C virus (HCV) has a lower prevalence in children and knowledge is limited regarding the natural outcome of HCV infection in children. AIM To study the risk factors of HCV acquisition and predictors of persistence in Egyptian children. METHODS Children, 1-9 years of age, were evaluated for acquisition of HCV (anti-HCV positive regardless of viraemia) and persistence of H...
The hepatitis C antibody reactivity rate in 91,748 blood donors tested using the ORTHO HCV C-100 ELISA system was 0.51%. Specificity of ELISA positive reactions was measured using a recombinant immunoblot assay (RIBA). The aim of this study was to identify markers in ELISA positive donors which were predictive of a RIBA positive result. Samples from 430 ELISA positive donors were tested by the ...
A retrospective cohort of injection drug users with newly acquired hepatitis C virus (HCV) infection was established to examine viral clearance. Newly acquired HCV infection was defined by anti-HCV antibody seroconversion within a 2-year interval. Stored serum samples were tested for HCV RNA, with viral clearance defined as >/=2 consecutive negative HCV RNA test results after infection. Ninety-...
Background. Hepatitis C virus (HCV) infection is the most common chronic blood-borne infection in the United States and a leading cause of morbidity and mortality. Previous analyses of the US National Health and Nutrition Examination Survey (NHANES) indicated approximately 3.6 million noninstitutionalized persons with antibody to HCV (anti-HCV). However, state-level prevalence remains less unde...
BACKGROUND Chronic seronegative hepatitis C virus (HCV) infection is defined as being HCV antibody (anti-HCV) negative, but HCV RNA positivity occurs in individuals infected with human immunodeficiency virus (HIV). However, associated factors are not well established because of the small number of reported cases. METHODS Multivariate logistic regression analysis of HIV-infected subjects from ...
Hepatitis C virus (HCV) infection affects ≥ 180 million individuals worldwide especially those living in developing countries. Recent advances in direct-acting therapeutics promise effective treatments for chronic HCV carriers, but only if the affected individuals are identified. Good treatment coverage therefore requires accurate epidemiological data on HCV infection. In 2014, we determined th...
Hepatitis C virus (HCV) infection is considered by the World Health Organization (WHO) to be a serious public health concern and one of the major public health priorities. In 2005, it was estimated that there are 185 million anti-HCV positive people in the world, which constitutes 2.8% of the global population. Our study estimates the anti-HCV seroprevalence in the working age population (15-64...
From 1992 to 1995 we studied 232 (69% male, 87% Caucasian) anti-human immunodeficiency virus (anti-HIV) positive Brazilian patients, through a questionnaire; HIV had been acquired sexually by 50%, from blood by 32%, sexually and/or from blood by 16.4% and by an unknown route by 1.7%. Intravenous drug use was reported by 29%; it was the most important risk factor for HIV transmission. The alanin...
The induction of protective or therapeutic cellular immunity against hepatitis C virus (HCV) is a difficult goal. In a previous work we showed that immunization with a recombinant adenovirus encoding HCV-NS3 (RAdNS3) could partially protect mice from challenge with a vaccinia virus encoding HCV antigens. We sought to investigate whether systemic administration of an immunostimulatory monoclonal...
