The host range of hepatitis B virus (HBV) is limited to humans and chimpanzees. As discussed in the literature, numerous studies in humans and chimpanzees have generated a great deal of information on the mechanisms that cause viral clearance, viral persistence, and disease pathogenesis during acute or chronic HBV infection. Relevant pathogenetic studies have also been performed in those few species representing natural hosts of hepadnaviruses that are related to HBV, such as the woodchuck hepatitis virus and the duck hepatitis virus. Further insight has been gained from multidisciplinary studies in transgenic or humanized chimeric mouse models expressing and/or replicating HBV to varying degrees. We provide here a concise summary of the available HBV mouse models as well as of the contributions of these models to our understanding of HBV pathogenesis.

Background: Splenectomy is an effective yet invasive intervention for alleviating portal pressure in patients with hepatitis cirrhosis. However, the current prognostic indicators for predicting long-term overall survival of these patients have several limitations.

Aim: To assess the potential of preoperative total bilirubin-albumin (B/A) ratio as a prognostic indicator for patients with hepatitis cirrhosis undergoing splenectomy.

Cholesterol metabolism regulator SREBP2 inhibits HBV replication via suppression of HBx nuclear translocation.

Front Immunol

January 2025

Department of Hepatology, Center for Pathogen Biology and Infectious Diseases, Institute of Translational Medicine, The First Hospital of Jilin University, Changchun, Jilin, China.

The intricate link between cholesterol metabolism and host immune responses is well recognized, but the specific mechanisms by which cholesterol biosynthesis influences hepatitis B virus (HBV) replication remain unclear. In this study, we show that SREBP2, a key regulator of cholesterol metabolism, inhibits HBV replication by interacting directly with the HBx protein, thereby preventing its nuclear translocation. We also found that inhibiting the ER-to-Golgi transport of the SCAP-SREBP2 complex or blocking SREBP2 maturation significantly enhances HBV suppression.

Background: Viral infections can increase the likelihood of an individual developing membranous nephropathy (MN). Limited information is available regarding the treatment approaches for such cases. We conducted a review focusing on hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV)-associated MN.

Unusual Cutaneous Manifestations in a Patient with a History of Hepatitis B: A Case of Scleromyxedema and Literature Review.

Clin Cosmet Investig Dermatol

January 2025

Department of Dermatology, Guangzhou Dermatology Hospital, Guangzhou, Guangdong, People's Republic of China.

Scleromyxedema (SM) is a rare primary cutaneous mucinosis characterized by systemic papules and scleroderma-like manifestations, often associated with monoclonal gammopathy. We present the case of a 37-year-old male with SM who developed yellowish plaques on the neck and back over three years. Histopathological examination revealed mucin deposition, fibroblast proliferation, and fibrosis, supporting the diagnosis.

Hepatitis B core-related antigen as a promising serological marker for monitoring hepatitis B virus cure.

World J Hepatol

January 2025

Department of Infectious Diseases, Institute for Viral Hepatitis, The Key Laboratory of Molecular Biology for Infectious Diseases, Chinese Ministry of Education, The Second Affiliated Hospital of Chongqing Medical University, Chongqing 400010, China.

Hepatitis B virus (HBV) infection is a global health concern. The current sequential endpoints for the treatment of HBV infection include viral suppression, hepatitis B e antigen (HBeAg) seroconversion, functional cure, and covalently closed circular DNA (cccDNA) clearance. Serum hepatitis B core-related antigen (HBcrAg) is an emerging HBV marker comprising three components: HBeAg, hepatitis B core antigen, and p22cr.
