In this cross sectional anonymous study, blood samples of 285 dentists and Physicians were tested for hepatitis B surface antigen (HBs Ag), hepatitis B envelope Ag (HBe Ag), antibodies to: hepatitis B suface (anti-HBs), hepatitis B core Ag (anti-HBc) and hepatitis B envelope Ag (anti-HBe) by ELISA-3 and antibody to hepatitis C virus (anti-HCV) by ELISA-3 and immunoblotting tests. The results su...
Acute hepatitis B virus (HBV) infection is typically distinguished from chronic disease by a positive IgM anti-hepatitis B core antigen (anti-HBc) test. Patients with chronic hepatitis B remain hepatitis B surface antigen (HBsAg) positive, often with raised serum alanine aminotransferase (ALT) activities, for more than six months. The presence of hepatitis B e antigen (HBeAg) and HBV-DNA correl...
BACKGROUND AND AIM The best strategy for managing patients with resolved hepatitis B virus infection (HBsAg negative, anti-HBc antibodies positive with or without anti-HBs antibodies) and hematological malignancies under immunosuppressive therapies has not been defined. The aim of this study was to prospectively analyze the risk of hepatitis B virus reactivation in these patients. MATERIAL AN...
The woodchuck hepatitis virus is a naturally occurring hepatitis B-like virus that infects the eastern woodchuck. Direct immunofluorescence staining for woodchuck hepatitis virus core antigen in liver biopsies demonstrated the presence of this antigen in 14 of 17 chronically infected woodchucks, and in 8 of 10 woodchucks undergoing acute infections. Fluorescent localization of woodchuck hepatit...
background and aims: many studies have provided evidence for the role of hepatitis b and c viruses in the development of liver cancer. although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with hbv and hcv. this study was performed to determine the frequency of hbv/hcv-coinfection in mashhad, north-east of iran. mat...
Receptor sites for polymerized human serum albumin (pHSA) on the envelope of hepatitis B virus (hepatitis B surface antigen) and antibodies to pHSA in sera of patients with liver disease were differentiated by an indirect fluorescent antibody method. Analysis of the specificities of pHSA receptors and antibodies to pHSA by hemagglutination inhibition suggested that pHSA receptors reacted with a...
Background & Aims: Hepatitis B virus is one of the causes of acute and chronic hepatitis. Due to multiple hospitalization and blood transfusion, thalassaemic patients are at higher risk of this infection. Duration of the immunity after vaccination in this high-risk group and the need for booster vaccination is uncertain. The aim of this study was to find antibody titration and immunity to Hepat...
conclusions we introduced an anti-hbsp antibodies elisa, designed for locally circulating hbv strains. correlation observed of anti-hbsp with liver fibrosis staging regardless of viral replication and liver inflammation suggests anti-hbsp antibodies as possible indicator for hbv-associated liver fibrosis. results seven out of eighty (9%) chb patients were positive for anti-hbsp antibodies. mean...
