can Isolated hepatitis B core antibody in HIV-infected patients response to hepatitis B vaccine help to elucidate the cause?

Persistence of immunity to hepatitis B vaccine as infants, 17 years earlier

Background: In Iran scince 1992, hepatitis B vaccination was a part of the national vaccination program. Hepatitis B vaccination is effective in the epidemiology of hepatitis B. The aim ofthis study was to evaluate the long – term persistence of immunity. Methods: This cross-sectional analytical study was conducted on children and adolescents aged between 6-18 years in Birjand, who recei...

The Study of Cerumen Hepatitis B Infection in Chronic Hepatitis B Patients by Real-Time PCR

Introduction: The hepatitis B is a viral infection that causes a big problem globally. About 2 billion people worldwide are infected and there are now about 400 million HBV-DNA carriers around the world. HBV infection is the ninth cause of death worldwide and infects about 350 million new cases each year in the world. HBV-DNA can be spotted in different body secretions and fluids, including se...

Surface protein mutations in chronic hepatitis B patients who received hepatitis B vaccine therapy

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...

Immune Response to Standard Hepatitis B Vaccination in HIV-Infected Patients

Background: Due to their similar routes of transmission, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infection occurs considerably. HBV infection progresses more rapidly in HIV-infected patients. Therefore, HBV vaccination of all non-immune HIV infected patients is recommended. On the other hand, HIV-infected subjects have suboptimal responses to HBV vaccine. In this study...

An Investigation of the Immune Response to Hepatitis B Vaccination in Hemodialysis Patients at Dialysis Centers of Tehran (2016)

Background: Hemodialysis (HD) patients are at an increased risk of acquiring the hepatitis B (HB) virus and having lower protective antibody levels as well as shorter durations of seroprotection. This study aims to determine the immune response of HB vaccination in HD patients referring to dialysis centers of the Tehran North Health Network. Materials and Methods: This descriptive study was co...
