the immune clearance phase or chronic hepatitis phase (hbeag-positive, high levels of serum hbv-dna, elevated alt, and active liver disease ), and the inactive carrier state or asymptomatic phase (hbsag-positive in serum without hbeag, hbv-dna levels than < 105 copies/ml, and normal alt lev...

Antibody to HCV (anti-HCV) can be detected in 30% of chronic hepatitis B, in 10-46% of alcoholic cirrhosis, in 40-70% of cases of hepatocellular carcinoma HBsAg negative and in 0-83% of patients with auto-immune chronic active hepatitis. Assays for HCV antigen will require technology ...
HDV prevalence was 41.9% whiting HBsAg carries and was associated with age (PR = 1.96; 95% CI 1.12-3.42; p = 0.01), hepatitis B virus (HBV) infection (PR = 4.38; 95% CI 3.12-6.13; p < 0.001), and clinical hepatitis (PR =1.44; 95% CI 1.03-2.00; p = 0.03)....
In order to evaluate the interference of hepatitis delta virus (HDV) in hepatitis B viral particle (HBsAg, HBcAg) expression in the liver of chronic HDV patients, 39 and 81 liver biopsies of HBsAg carriers seropositive for anti-HDV and anti-HDV negative controls, respectively, were studied. ...
Viral replication, over than 10^sup 3^ copies/ml, was detected in 61% of positive HBsAg patients. Three viral genotypes were detected: D (95%), B (3%) and A (3%). Occult hepatitis was detected in 4% of sera with "anti-HBc isolated" profile. In conclusion, the risk of vertical ...
Objective: To evaluate the applicability of SBA-15 silica as an adjuvant in immunizations with purified particles of the viral protein HBsAg, the main component of hepatitis B vaccine, Butang , produced by Instituto Butantan. Methods: BALB/c mice orally or subcutaneously received 0.5 g of HBsAg...
Occult hepatitis B virus (HBV) infection is a peculiar form of chronic viral infection identified since the early 80's and can be defined as the presence of HBV DNA in the serum and/or in the liver tissue of patients negative for the HBV surface antigen (HBsAg) using usual serological ...
The yeast Saccharomyces cerevisiae, which produces huge quantities of the surface antigens of the human virus of the B hepatitis HBsAG, HBpreS2Ag and HbpreS1Ag are constructed by using methods of gene engineering. The effective biosynthesis of antigens in the yeast was achieved by the use of...
