Published: April 2023

Background: Hepatitis E virus (HEV) is the most common cause of acute viral hepatitis, and mainly transmitted via faecal-oral contamination or consumption of contaminated food products. However, limited data on the surface stability and HEV sensitivity to chemical disinfectants are available.

Aim: To establish an HEV-based carrier assay to evaluate its surface stability and the virucidal activity of nine surface disinfectants.

Methods: A recently developed robust HEV-3 cell culture system for an HEV-based carrier assay.

Findings: Alcohol-based disinfectants were insufficient to eliminate HEV infectivity, whereas disinfectants based on aldehyde, peracetic acid, oxygen, and/or quaternary ammonium inactivated HEV.

Conclusion: These findings have strong implications for the recommendation of evidence-based hygiene guidelines to reduce HEV transmission.

Hepatitis B virus (HBV) infection is a major global health concern, with liver transplantation (LT) serving as a critical treatment for end-stage liver disease caused by HBV. However, the risk of HBV reinfection after LT remains significant, necessitating effective prophylaxis. Today, the combination of hepatitis B immune globulin (HBIG) and high-barrier nucleos(t)ide analogues (NUCs) is the standard of care for preventing HBV recurrence post-LT but concerns about the cost of HBIG and access to high-barrier NUCs have led to a reduction in the use, dose, and duration of HBIG in recent years.

Background: Glecaprevir/pibrentasvir is an effective antiviral therapy for hepatitis C virus infection and is generally regarded safe in patients with renal impairment. However, renal complications are a notable, albeit rare, concern.

Case Presentation: We report a case of acute kidney injury in a man in his 50s with chronic hepatitis C virus, chronic obstructive pulmonary disease, morbid obesity, a history of heroin dependence, and untreated type 2 diabetes mellitus.

Background: Patients with chronic hepatitis B virus (HBV) infection are characterized by impaired immune response that fails to eliminate HBV. Immune checkpoint molecules (ICMs) control the amplitude of the activation and function of immune cells, which makes them the key regulators of immune response.

Methods: We performed a multiparametric flow cytometry analysis of ICMs and determined their expression on intrahepatic lymphocyte subsets in untreated and treated patients with HBV in comparison with non-pathological liver tissue.

Background: Inflammation is a critical component in the process of resolved hepatitis B virus (HBV) infection. The neutrophil-to-lymphocyte ratio (NLR) serves as a sensitive indicator of systemic inflammation and immune activation. Our study aimed to investigate the correlation between elevated NLR levels and the risk of all-cause mortality in patients with resolved HBV infection.
