The purpose of this study is to develop and characterize immunological assays on blood samples.
Chronic hepatitis B patients of the following 4 groups will be asked to participate in the study:
- Group A: Immune tolerant patients
- Group C: Healthy carriers
- Group D: Hepatitis B envelope antigen (HBeAg)-negative chronic hepatitis B patients
Allocation: Non-Randomized, Intervention Model: Parallel Assignment, Masking: Open Label

The majority of childbearing age women with hepatitis B virus infection were still in the immune tolerance period. Our recent research had shown that most puerperae after delivery had elev...
The study consists to Identify viral variants involved in the transmission of hepatitis C and characterize the antigenic and functional properties of their envelope glycoproteins at very e...
Does vaccinating hemodialysis patients with Twinrix® (combination vaccine against hepatitis A and hepatitis B) result in a difference in hepatitis B antibody response in comparison to the...
The goals of therapy against chronic hepatitis B are to decrease the morbidity and mortality related to chronic HBV infection. Currently available antiviral therapy can suppress viral repl...
This study will identify and characterize immune factors involved in hepatitis C infection and elimination of the virus. Individual responses to hepatitis C infection vary; some people ar...
Worldwide there is variation in prevalence of Hepatitis D viral infection. Superinfection and co infection with hepatitis B viral infection is known to occur in 15-20 million people.
Blood transfusion is one route of transmission of hepatitis E virus (HEV). The aim of this study was to assess both the prevalence of HEV antibodies and HEV infection in New Zealand blood donors.
Dried blood spots (DBS) specimens can be used for hepatitis C virus (HCV) infection screening in cases where serum specimens are difficult to obtain. However, uncertainties surround the sensitivity an...
Persons with HIV infection are at increased risk for hepatitis B virus infection. In 2016, the World Health Organization resolved to eliminate hepatitis B as a public health threat by 2030.
This study was carried out to determine the incidence of HBV infection in the young generation born after mandatory implementation of hepatitis B vaccination since 1992. Repeat blood donors born betwe...
INFLAMMATION of the LIVER in humans due to infection by VIRUSES. There are several significant types of human viral hepatitis with infection caused by enteric-transmission (HEPATITIS A; HEPATITIS E) or blood transfusion (HEPATITIS B; HEPATITIS C; and HEPATITIS D).
INFLAMMATION of the LIVER in humans caused by HEPATITIS DELTA VIRUS, a defective RNA virus that can only infect HEPATITIS B patients. For its viral coating, hepatitis delta virus requires the HEPATITIS B SURFACE ANTIGENS produced by these patients. Hepatitis D can occur either concomitantly with (coinfection) or subsequent to (superinfection) hepatitis B infection. Similar to hepatitis B, it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.
INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally, and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.
Physiological and psychological symptoms associated with withdrawal from the use of a drug after prolonged administration or habituation. The concept includes withdrawal from smoking or drinking, as well as withdrawal from an administered drug.
A family of hepatotropic DNA viruses which contains double-stranded DNA genomes and causes hepatitis in humans and animals. There are two genera: AVIHEPADNAVIRUS and ORTHOHEPADNAVIRUS. Hepadnaviruses include HEPATITIS B VIRUS, duck hepatitis B virus (HEPATITIS B VIRUS, DUCK), heron hepatitis B virus, ground squirrel hepatitis virus, and woodchuck hepatitis B virus (HEPATITIS B VIRUS, WOODCHUCK).

An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produc...
