Background Hepatitis A virus (HAV) can cause significant pathology in patients with chronic hepatitis B virus (HBV), however, HAV can be prevented by vaccination. The aim of this study was to determine the implication of vaccination against HAV vaccine in patients with chronic hepatitis B. Materials and methods The seroprevalence of anti-HAV IgG antibodies was investigated in the patients wit...

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...

OBJECTIVES To determine the prevalence of antibodies to hepatitis B core antigen, hepatitis C virus, and HIV in entrants to Irish prisons and to examine risk factors for infection. DESIGN Cross sectional, anonymous survey, with self completed risk factor questionnaire and oral fluid specimen for antibody testing. SETTING Five of seven committal prisons in the Republic of Ireland. PARTICIP...

OBJECTIVE To review management of incidents involving exposure to blood reported to an occupational health unit. DESIGN Analysis of all reported incidents from January 1989 to June 1991. SETTING London teaching hospital. SUBJECTS 447 health care workers and students. MAIN OUTCOME MEASURES Immunisation against hepatitis B virus before exposure, proportion of known source patients tested ...

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...

The full-length putative structural proteins encoded by open reading frame 2 (ORF2) and ORF3 of hepatitis E virus have been cloned and expressed in recombinant baculovirus. Sera obtained from 28 Sudanese pediatric patients with acute hepatitis and 19 pediatric control patients were analyzed for reactivity to hepatitis E virus by using the baculovirus-expressed ORF2 and ORF3 proteins in a Wester...

results 12 (14.8%) patients had positive results for both hdv rna and anti-hdv. the mean alt level was higher in hdv positive patients (75.9 u/ml) than hbv-mono-infected individuals; however, the mean hbv viral load was lower in coinfected patients than hbv-mono-infected patients. phylogenetically, genotype i was the only detected genotype, and the most closely related isolates were of turkish,...

Co infection with hepatitis C virus and hepatitis D virus (HDV) is less common than that with HIV and HCV, although more attention has been given to HCV co infection as a result of its higher frequency of chronic disease. The present investigation was attempted to determine the exact prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis D virus (HDV) infection among liver...
