BACKGROUND Co-infections of hepatitis B and C viruses are frequent with HIV due to shared routes of transmission. In most of the tertiary care health settings, HIV reactive patients are routinely tested for HBsAg and anti-HCV antibodies to rule out these co-infections. However, using the routine serological markers one can only detect active HBV infection while the occult HBV infection may be m...

I read with interest the article by Stief et al. published in your journal recently1. It showed us that hepatitis B virus (HBV) infection remains a significant problem in prisons, and it was related with other published studies2,3. The finding on higher prevalence of HBV infection in the male gender and in prisoners with positive history of intravenous drug use and STD demonstrated a new strate...

BACKGROUND Patients under haemodialysis are considered at high risk to acquire hepatitis B virus (HBV) infection. Since few data are reported from Brazil, our aim was to assess the frequency and risk factors for HBV infection in haemodialysis patients from 22 Dialysis Centres from Santa Catarina State, south of Brazil. METHODS This study includes 813 patients, 149 haemodialysis workers and 77...

The clinical course of 10 liver transplant recipients who had hepatitis B virus (HBV) and five recipients with HBV and D (delta) infection before transplantation is described. Six patients who underwent eight transplants died. The estimated one and two year survival rates in patients with HBV only before transplantation were 74% and 67% respectively. The estimated one and two year survival in p...

CONTEXT The clinical outcome of hepatitis B virus (HBV) infection is variable, ranging from spontaneous recovery to an inactive carrier state, chronic hepatitis, occult HBV infection, liver cirrhosis, or hepatocellular carcinoma. EVIDENCE ACQUISITION This variable pattern and clinical outcomes of the infection were mainly determined by virological and host genetic factors. Since the most of h...

During previous studies of susceptibility to hepatitis B virus (HBV) infection, HBV DNA was detected in 2/6 wild-caught baboons. In the present study, HBV DNA was amplified from 15/69 wild-caught baboons. All animals were negative for HBV surface antigen and antibody against HBV core antigen. Liver tissue from 1 baboon was immunohistochemically negative for HBV surface antigen but positive for ...

Dysfunctional CD8+ T cells present in chronic virus infections can express programmed death 1 (PD-1) molecules, and the inhibition of the engagement of PD-1 with its ligand (PD-L1) has been reported to enhance the antiviral function of these T cells. We took advantage of the wide fluctuations in levels of viremia which are typical of chronic hepatitis B virus (HBV) infection to comprehensively ...

conclusions the mir-155 appeared to be suppressed during hbv infection. the significantly higher mir-155 levels in alt-elevated patients infected with hbv suggest that mir-155 levels in pbmcs correlate with the immune state of patients with chronic hbv infection. results in the hbv-infected patients, the mir-155 levels were significantly lower than in the healthy controls (p = 0.001). chronic h...

Hepatitis B virus (HBV) is the leading cause of chronic liver disease and liver-related death worldwide, with the majority of these cases occurring in areas of Africa and Asia where HBV prevalence is high. Many of the countries that are affected by hepatitis B are also affected by a high HIV burden, leading to frequent HIV/HBV co-infection. The consequences of co-infection, including increased ...
