A sentinel study on viral hepatitis is currently being carried out in the village of Cavunge in a semiarid rural region of the state of Bahia, northeastern Brazil. This study has identified individuals in whom anti-HBc IgG was the only serological marker for hepatitis B virus (HBV). This serological pattern may constitute evidence of occult HBV infection. This study Investigated the possibility...

UNLABELLED Previous studies have suggested that prior exposure to hepatitis B virus (HBV) infection may increase the risk of development of hepatocellular carcinoma (HCC) in patients with chronic hepatitis C. The aim of this study was to compare the prevalence of previous or occult HBV infection in a cohort of hepatitis B surface antigen-negative patients with histologically advanced chronic he...

In this issue of the Iranian journal of Kidney Diseases, the case report of “Successful Pregnancy in a Kidney Transplant Recipient With Chronic Hepatitis B Virus Infection” by Kashif and colleagues1 confronts us to different challenging topics in nephrology. First, hepatitis B virus (HBV) infection has been discovered after kidney transplantation with a negative report of hepatitis B surface an...

Aim . Assessment of the clinical impact previous hepatitis B infection (PHB). Key points PHB is characterized by presence viral DNA in organism (including intrahepatic cccDNA and integrated DNA). Possible virus persistence patient's hepatocytes potentiates agent transmission risk via haemotransfusion, organ transplantation haemodialysis. Occult HBV individuals can reactivate at background immun...

Introduction and objective: Hepatitis B virus (HBV) is a member of Hepadnaviridae and a major causative agent of chronic and acute hepatitis, liver cirrhosis and hepatocellular carcinoma. Genotype determination of HBV is based on PCR-RFLP and sequencing of genome of the virus. The genotype formation is mainly due to mutations of HBV precore, S, and YMDD (tyrosine-methionine-aspartate-aspartate ...
