Chronic hepatitis B virus (HBV) infection is influenced by both viral and host factors. In genome-wide association studies, the human leucocyte antigen HLA-DPA1 and related polymorphism rs3077 were found to be associated with susceptibility to and spontaneous clearance of HBV infection. Here, we evaluated the association between HLA-DPA1 mRNA expression and the risk of HBV infection. HLA-DPA1 and rs3077 polymorphisms were investigated in 169 patients with chronic HBV and 217 healthy controls (HCs) from Sichuan Han blood donors using sequence-based typing and meta-analysis for HLA-DPA1 alleles. HLA-DPA1 mRNA levels were measured by real-time polymerase chain reaction. The results showed that HLA-DPA1 and rs3077 were associated with HBV infection in the Sichuan population. Rs3077T and DPA1*01:03 played protective roles in HBV infection, and rs3077C and DPA1*02:02 increased susceptibility to HBV infection. We found that the HLA-DPA1 mRNA expression was decreased in the CHB group; in particular, the 3077CT, 3077TT, DPA1*01:03 and DPA1*02:01 alleles showed a significant decrease. Our results demonstrated, for the first time, that expression of HLA-DPA1 alleles and rs3077 affected the risk of HBV infection. Genotypes with lower HLA-DPA1 expression had a greater susceptibility to HBV infection. Thus, further independent studies are needed to strengthen the associations of these polymorphisms with susceptibility to and clearance of HBV infection in Chinese populations.

Aim: This research was aimed to uncover the hepatitis B virus (HBV) and hepatitis C virus (HCV) related diseases burden in Asia over the past 3 decades, estimating from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019.
Methods: Age-standardised rates, case numbers of prevalence, disability-adjusted life-years (DALYs), incidence and deaths with 95% uncertainty intervals (UI) for HBV/HCV-related diseases from 1990 to 2019 were derived from GBD 2019 database, with the estimated annual percentage changes (EAPCs) calculated. Our analysis also encompassed the association between the Sociodemographic Index (SDI) and the burden of HBV/HCV-related diseases, future disease burden predictions in six selected countries and various risk factors.

In this article, we provide commentary on the recent article by Zhao . We focus on the shifts in the gut microbiota of patients with hepatitis B virus (HBV)-associated cirrhosis/portal hypertension (PH) following transjugular intrahepatic portosystemic shunt (TIPS) and the implications for understanding the mechanisms, diagnosis, and treatment. By comparing the gut microbiota composition and dynamic changes before and after TIPS in patients with and without hepatic encephalopathy, the authors found an increase in non-probiotic bacteria in those who developed hepatic encephalopathy post-TIPS, with species present only in the hepatic encephalopathy group.

Background: Chronic hepatitis B virus (HBV) infection is a major risk for development of hepatocellular carcinoma (HCC), a frequent malignancy with a poor survival rate. HBV infection results in significant endoplasmic reticulum (ER) stress and activation of the unfolded protein response (UPR) signaling, a contributing factor to carcinogenesis. As part of the UPR, the ER-associated degradation (ERAD) pathway is responsible for removing the burden of misfolded secretory proteins, to re-establish cellular homeostasis.

Viral hepatitis B is infamous for being contracted in young adulthood and adolescence, as high-risk behaviors like unprotected sexual intercourse and intravenous drug abuse are common. Most infections caused by the hepatitis B virus (HBV) are cleared without any long-term sequelae, but some may persist and cause chronic hepatitis B (CHB). This chronicity may produce a state of prolonged inflammation and significantly increase the risk of developing colorectal adenomas (CRA) and colorectal carcinomas (CRC).
