Background: Chronic hepatitis B (CHB) remains a global health dilemma with high morbidity and mortality. Human males absent on the first (hMOF) (a histone acetyltransferase) is responsible for DNA damage repair, tumorigenesis and cell cycle regulation. Persistence of HBV DNA contributes to cirrhosis and hepatocellular carcinoma (HCC) in CHB patients. Histone acetyltransferase enhances HBV replication, however the precise underlying mechanism of hMOF in HBV replication in CHB patients remains to be explored. This study aims to investigate the correlation between hepatic hMOF and HBV DNA replication in CHB patients, and may provide new insights towards the treatment of CHB patients.
Methods: hMOF in liver biopsy (CHB, n = 33 HBeAg; n = 20 HBeAg, and three healthy controls) was determined, using immunohistochemistry, qPCR and Western blot. The correlation between hMOF and HBsAg, as well as, HBeAg were determined.
Results: A positive correlation between hMOF and HBV DNA in overall CHB patients was observed. A distinct positive correlation between hMOF and HBsAg and/or HBeAg in HBeAg CHB patients was also detected, however not observed between hMOF and HBsAg in HBeAg CHB patients. No correlation was observed between hMOF and hepatic inflammation severity and fibrotic stage in CHB patients.
Conclusions: Hepatic hMOF might contribute to host HBV clearance in CHB patients and possible pathogenesis.

Probability analysis of hepatocellular carcinoma in hepatitis patients in the gray zone.
Front Med (Lausanne)
December 2024
Department of Infectious Diseases, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, China.
Objective: To investigate the probability of hepatocellular carcinoma (HCC) in a large number of gray-zone (GZ) patients with chronic hepatitis B (CHB) in clinical practice.
Methods: The patients with CHB who were diagnosed and treated in our hospital from January 2013 to January 2023 were analyzed retrospectively.
Results: According to the different levels of HBeAg, ALT and HBV DNA, GZ patients were divided into four categories: (1) Gray zone A (GZ-A): HBeAg positive, normal ALT level, HBV DNA ≤ 10 IU/ml; (2) Gray zone B (GZ-B): HBeAg positive, ALT>ULN, HBV DNA ≤ 2 × 10 IU/ml; (3) Gray zone C (GZ-C): HBeAg negative, normal ALT level, HBV DNA ≥ 2 × 10 IU/ml; and (4) Gray zone D (GZ-D): HBeAg negative, ALT > ULN, serum HBV DNA ≤ 2 × 10 IU/ml.
Complete Heart Block in a Patient Declining Pacemaker Implantation: A Discussion on Patient-Centered Care and Shared Decision-Making.

Permanent pacemaker (PPM) implantation is the standard of care in patients with complete heart block (CHB) and second-degree type II atrioventricular (AV) block irrespective of patient symptoms when the conduction abnormality is irreversible. CHB generally constitutes a medical emergency that can be fatal if not urgently treated. This is in contrast to first-degree AV block and second-degree type I AV block, which require PPM implantation only in very special circumstances.

Coexistence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) has been observed in some chronic hepatitis B (CHB) patients (DP patients), but the clinical outcomes and comprehensive characterization of immune micro-environmental changes for this specific population remain inconclusive. In this study, we retrospectively analyze the prognosis of 305 patients in Foshan City, Guangdong Province, China, and also investigated the molecular immunology changes in HBsAg and anti-HBs double positive CHB patients (DP group), CHB patients who had recovered from IFN-ɑ treatment (RP group), and healthy controls (HC group) using T cell receptor (TCR) and B cell receptor (BCR) immune repertoire sequencing. Our findings revealed that 22.

Background & Aims: Flares after nucleos(t)ide analogue (NA) cessation are common and potentially harmful. Predictors of flares are required for risk stratification and to guide off-treatment follow-up.
Method: This multicenter cohort study included virally suppressed patients with chronic hepatitis B (CHB) who were hepatitis B e antigen negative at NA cessation.

This study aimed to investigate the impact of IL-35 on the prognosis of patients with HBV-ACLF. We recruited 69 patients with HBV-ACLF, 20 patients with chronic hepatitis B (CHB), 17 patients with liver cirrhosis (LC), and 20 healthy controls (HCs) from a regional infectious disease treatment center in China. Plasma levels of IL-35 at baseline were detected using ELISA.
