Protective measures against occupational exposure to the hepatitis B virus (HBV) and hepatitis C virus (HCV) must be taken in order to prevent infection in dental care workers. To determine the best way to protect these workers, our study examined viral hepatitis infection in dental care workers in regions with a high prevalence of HCV infections in Japan. In total, 141 dental care workers (inc...

BACKGROUND Several retrospective and prospective studies report an increased prevalence of non-organ-specific autoantibodies (NOSAs) in patients with hepatitis C virus (HCV) related chronic liver disease (CLD). Some of the data so far available are controversial and the true prevalence of NOSAs in the general population is still not known. AIM To explore the prevalence of NOSAs, their relatio...

The aim of this study was to determine if knowledge of both the serum HCV RNA and serum anti core IgM antibody status enabled one to predict the histological severity in chronic hepatitis C. We studied 45 female patients with chronic hepatitis C infection. The presence or absence of IgM antibodies to HCV and HCV RNA by PCR in each patient's serum was determined. Liver biopsies performed were sc...

Identification of anti-hepatitis C virus (anti-HCV) human antibody clones with broad neutralizing activity is important for a better understanding of the interplay between the virus and host and for the design of an effective passive immunotherapy and an effective vaccine. We report the identification of a human monoclonal Fab (e137) able to bind the HCV E2 glycoprotein of all HCV genotypes but...

AIM This study was designed to evaluate the frequency of antibody against these viruses in individuals attending the endoscopy ward of Taleghani hospital Tehran, Iran. BACKGROUND Blood-borne viruses such as hepatitis B and hepatitis C virus and HTLV-1 virus are among the world's public health problems. Hepatitis viruses cause liver problems and HTLV-1 infection can lead to adult T-Cell lympho...

INTRODUCTION Occult hepatitis B infection (OBI) is considered to be one of the major risks for patients suffering from end-stage renal disease (ESRD) on regular hemodialysis (HD) and patients with chronic hepatitis C virus (HCV) infection. This study compared the prevalence of OBI among these two high-risk groups in the Suez Canal region, Northeastern Egypt, to obtain a better national overview...

Hepatitis C virus (HCV) is an important health care problem in haemodialysis. Hepatitis C virus is both a cause and complication of kidney diseases. Yet there are limited information on antibody against HCV in patients on haemodialysis. The purpose of this study was to determine the prevalence of anti-HCV and the risk factors associated with HCV infection in a cohort of 100 participants on haem...

The performance of a fully automated, random access, enhanced chemiluminescence immunoassay (Ortho/ECi) for the detection of antibody to hepatitis C virus (HCV) (anti-HCV), HBsAg, and antibody to HBsAg (anti-HBsAg), in human serum was compared to a Abbott second-generation enzyme immunoassay (EIA 2.0). The Ortho/ECi assays employ an immunometric technique with enhanced chemiluminescence for opt...

BACKGROUND The relationship between hepatitis C virus (HCV) infection and acute or chronic glomerulonephritis (GN) is not well understood. METHODS Two hundred and eighty-four patients with biopsy-proven GN and other renal diseases were studied in a multicentre survey performed during the period 1992-1995. Several clinical parameters were collected for each patient at the time of renal biopsy....
