AIMS The aim of this study was to investigate the genomic mutations in the circulating Hepatitis B virus strains causing infection in the Indian population. Further, we wanted to analyze the biological significance of these mutations in HBV mediated disease. METHODS 222 HBsAg positive patients were enrolled in the study. The genotype and mutation profile was determined for the infecting HBV i...

Chronic hepatitis B is considered a major public health problem, and its treatment entails increasing health budget expenses with high-cost drugs covered by Unified National Health System. The objective of this study was to compare the efficacy of interferon (conventional; pegylated - PEG2a) and lamivudine (LAM) for the treatment of chronic hepatitis B through a systematic review, selecting ran...

A novel hepatitis B virus (HBV) strain (W29) was isolated from serum samples in the northwest of China. Phylogenetic and distance analyses indicate that this strain is grouped with a series of distinct strains discovered in Vietnam and Laos that have been proposed to be a new genotype I. TreeOrderScan and GroupScan methods were used to study the intergenotype recombination of this special group...

To determine the prevalence of serological markers of viral hepatitis B in university students of the city of Abancay, we performed a cross-sectional study on 240 students from three universities, from January to October 2010. Informed consent was requested to every student, an epidemiological record was filled, and a venous blood sample was drawn to determine the presence of HBsAg, total anti ...

Nine children born to HBsAg positive mothers, who became chronic HBsAg carriers with associated liver disease, were followed for five to 10 years. Five children with active hepatitis or active cirrhosis at presentation achieved complete remission within six years, while three HBeAg positive patients with minimal histological lesions remained unchanged.

BACKGROUND Early age at infection with hepatitis B virus (HBV) increases the risk of chronic HBV infection. In addition early age at infection may further increase the risk of persistent viral replication beyond its effect on chronicity. The effects of perinatal and early postnatal transmission on the risk of prolonged hepatitis B e antigenaemia in children with chronic HBV infection are not we...

Entecavir is a guanosine analogue with activity against hepatitis B virus. The aim of this 4-year trial was to evaluate entecavir treatment in nucleos(t)ide-naïve HBeAg-positive chronic hepatitis B patients. Forty-nine patients received entecavir and nine of them withdrew from the trial at the end of week 96. The initial mean value of alanine aminotransferase was 79.4 +/- 41.5 IU/L, and at the ...

Background The presence of HBV DNA in the liver (with detectable or undetectable HBV DNA in the serum) of individuals tested HBsAg negative by currently available assays is defined occult B Infection (OBI). It remains a potential transmission threat and risk to HBV chronic infection. The purpose of this study was to determine the OBI prevalence among HBsAg negative subjects and to characterize ...

The Hepatitis B virus (HBV) genome has a circular, partially double stranded DNA. It belongs to the hepadnaviridae family of viruses and replicates within infected liver cells. The HBV is not a cytotoxic virus. Viral nucleocapsid antigens, HBeAg and/or HBcAg, expressed with HLA class I antigens on the hepatocytes plasma membrane are believed to be the major targets for activated cytotoxic T cel...

A total of 250 hepatitis B surface antigen positive sera were screened for antibody to hepatitis B surface antigen. It was found that seven (3%) sera showed concurrently circulating surface antigen and surface antibody to hepatitis B virus. The level of antibody to surface antigen was not affected by HBeAg and most of the cases were found in chronic hepatitis B carriers.
