BACKGROUND Delayed-type hypersensitivity (DTH) test responsiveness is associated with HIV disease progression; however it is unknown whether other immune markers, such as hepatitis B virus (HBV) vaccine seroresponse, also predict HIV outcomes. METHODS Eligible participants received HBV vaccine after HIV diagnosis, had non-anergic DTH testing at the time of last HBV vaccination, and available ...

Background & Aims: Hepatitis B virus is one of the causes of acute and chronic hepatitis. Due to multiple hospitalization and blood transfusion, thalassaemic patients are at higher risk of this infection. Duration of the immunity after vaccination in this high-risk group and the need for booster vaccination is uncertain. The aim of this study was to find antibody titration and immunity to Hepat...

Hepatitis B virus (HBV) causes significant global health problems despite the presence of a potential vaccine. HBV chronic cases are increasing rapidly in developing countries like Bangladesh. Here, we report the complete genome sequence of an HBV genotype C strain isolated from a chronic patient identified at an outdoor hospital section.

Women (175) who participated in an in vitro fertilization (IVF) programme were possibly exposed to hepatitis B virus. Later it became evident that 79 women had a hepatitis B infection, 49 were exposed but not infected and 47 were not exposed. Hepatitis B immunoglobulin (HBIg) and recombinant hepatitis B vaccine (HBvaxDNA) were offered to all women and partners except for those with established ...

BACKGROUND Hepatitis B is an important public health concern in South Africa (SA). The hepatitis B virus (HBV) vaccine was introduced into the South African Expanded Programme on Immunisation (EPI-SA) in 1995. There is no 'catch-up' programme in place. The duration of protection after hepatitis B vaccination in the SA population is unknown. Waning of vaccine-induced immunity leaves people at ri...

Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus (HBV) and is a major global health problem. HBV is the most common serious viral infection and a leading cause of death in mainland China. Around 130 million people in China are carriers of HBV, almost a third of the people infected with HBV worldwide and about 10% of the general population in the coun...

 ABSTRACT Background: Hepatitis B virus (HBV) infection in patients who lack detectable hepatitis B surface antigen (HBsAg) is called occult hepatitis B infection. Such infections have been frequently identified in patients with chronic hepatitis Cliver disease, but their prevalence is not known. Methods: 207 patients with chronic hepatitis C who were HCV -RNA and antiHCV positive were stu...

objective (s):the aim of this study was to determine the correlation between vaccine therapy and appearance of mutations in hepatitis b surface antigen (hbsag)-positive chronic hepatitis b virus (hbv) patients. materials and methods: 16 patients received the hbv vaccine and another 16 individuals from the control group did not. the surface gene was amplified and directly sequenced from samples ...

Lamivudine monoprophylaxis against hepatitis B virus (HBV) reinfection after liver transplantation is associated with recurrence due to escape mutants and second generation recombinant HBV vaccine is not effective. We studied the efficacy of two courses each of three double-doses (20 microg) of third-generation recombinant pre-S containing vaccine (Sci-B-Vac) in 20 patients on lamivudine prophy...

This commentary describes the need for a birth dose monovalent hepatitis B virus (HBV) vaccine and an effective programme for the prevention of mother-to-child-transmission (MTCT) of HBV in Africa. Current World Health Organization guidelines recommend routine maternal screening for HBV followed by treatment of highly infectious HBV-infected mothers, and HBV birth dose vaccination and the admin...
