Hepatitis B virus (HBV)-specific T-cell responses are important in the natural history of HBV infection. The number of known HBV-specific T-cell epitopes is limited, and it is not clear whether viral evolution occurs in chronic HBV infection. We aimed to identify novel HBV T-cell epitopes by examining the relationship between HBV sequence variation and the human leukocyte antigen (HLA) type in ...
BACKGROUND/AIMS The widespread use of cytotoxic chemotherapy and immunosuppressants has resulted in reactivation of hepatitis B virus (HBV) recently becoming an issue. Although rituximab (an anti-CD20 monoclonal antibody) has revolutionized the treatment of lymphoma, recent reports have suggested that rituximab therapy increases the risk of viral-mediated complications, and particularly HBV rea...
background: the outcome of hepatitis b virus (hbv) infection is chronic or resolved hbv infection. over the time, the levels of hbsag or anti-hbs declined and were not detectable in their sera and was named as isolated anti-hbc. the purpose of this study was to assess the prevalence of isolated anti-hbc in previously hbv infected individuals.methods: from april 2000 to september 2008, the resul...
Although the prevalence of chronic hepatitis B virus (HBV) infection in patients with chronic kidney disease remains low in developed countries, clinicians should be aware of the rationale for treatment in this setting. This patient population presents particular features and various complicating conditions requiring special treatment strategies. Interferon, the standard treatment for HBV infec...
Background: It has been arguedthat unprecedented degree of human leukocyte antigen (HLA) loci polymorphism within a population is requiredto avoid the devastating effects of infectious diseases. The present study was conducted to determine the associations between some of HLA classI genes and the outcome of hepatitis B virus (HBV) infection. Methods: Using sequential sampling method, 64 individ...
BACKGROUND Chronic hepatitis B virus (HBV) infection related hepatocellular carcinoma (HCC) is a major health problem in the Asia-Pacific region including Thailand. Several factors have been proposed as contributing to hepatocarcinogenesis. This study was aimed to investigate the impact of CYP2C19 genotypic polymorphism in HCC related to chronic HBV infection in Thailand. MATERIALS AND METHOD...
Previous studies have revealed the association between SNPs located on human leukocyte antigen (HLA) class II genes, including HLA-DP and HLA-DQ, and chronic hepatitis B virus (HBV) infection, mainly in Asian populations. HLA-DP alleles or haplotypes associated with chronic HBV infection or disease progression have not been fully identified in Asian populations. We performed trans-ethnic associ...
BACKGROUND Immune cells and molecules play a vital role in initiating, maintaining, regulating immunological homeostasis and inflammation in many pathological and physiological processes; however, the changes on expressions and functions of these cells and molecules in hepatitis B virus (HBV) infection have not been elucidated well. OBJECTIVES The current study aimed to determine the expressi...
Hepatitis B, a common infectious disease of liver, is transmitted by blood and body fluids like semen and vaginal fluid that carry hepatitis B virus (HBV). In chronic infection, medical care is required to decrease possibility of cirrhosis and liver cancer. In the present report, the hepatoprotective effect of an Echinacea purpurea preparation (Echiherb®) has been described...
AIM To explore whether copy number variations (CNVs) of toll-like receptor 7 (TLR7) are associated with susceptibility to chronic hepatitis B virus (HBV) infection. METHODS This study included 623 patients (495 males and 128 females) with chronic hepatitis B virus infection (CHB) and 300 patients (135 females and 165 males) with acute hepatitis B virus infection (AHB) as controls. All CHB pat...
