We tested the frequency of occult hepatitis B infection (OBI) among Egyptian healthcare workers (HCWs). We tested 132 HCWs for hepatitis B virus (HBV) DNA by nested polymerase chain reaction (PCR), and hepatitis C virus antibody (anti-HCV) by ELISA. HCV RNA was measured by nested PCR in anti-HCV-positive HCWs. HBV-DNA-positive HCWs were subjected to HBV genotyping. We included 132 HCWs who were negative for hepatitis B surface antigen and positive for hepatitis B core antibody (anti-HBc). OBI was detected in 7 male HCWs, and HBV E genotype was detected in 3, HBV D in 2 and HBV D and E in 2. Two OBI-positive HCWs had a history of neonatal hepatitis B vaccination. Anti-HCV seropositivity was detected in 17 HCWs who were positive for anti-HBc; 15 of whom were positive for HCV RNA by nested PCR. HCV infection was confirmed by anti-HCV and HCV RNA in 1 of 7 HCWs with OBI. In conclusion, Egyptian HCWs have a significant rate of OBI and HBV E genotype is prevalent.

Orthoflaviviruses are emerging arthropod-borne pathogens whose replication cycle is tightly linked to host lipid metabolism. Previous lipidomic studies demonstrated that infection with the closely related hepatitis C virus (HCV) changes the fatty acid (FA) profile of several lipid classes. Lipids in HCV-infected cells had more very long-chain and desaturated FAs and viral replication relied on functional FA elongation and desaturation.

The determinants of hepatitis C virus (HCV) viral load remain incompletely understood and may differ in females, who are relatively protected from the consequences of HCV infection during their reproductive years. We aimed to evaluate how age affects the relationship between sex and viral load. = 922 patients (males = 497, median age 62 years), all naïve to direct antiviral agents, were studied.

Free-of-charge hepatitis C virus antibody (HCV Ab) screening in some key populations and in 1969-1989 birth cohorts have been funded in Italy as the first step in confirming diagnosis in individuals who may be unaware of their infection. The purpose of this study is to leverage existing in-hospital routine screening data to better understand the distribution of HCV. A retrospective study of hospitalized patients (PTs) tested for HCV Ab for 5 years (from January 2017 to December 2022) in San Raffaele hospital was conducted according to age categories: birth year group before 1947 (patients older than 76 years old), birth year group 1947-1968, birth year group 1969-1989, and two other groups with birth year groups 1990-2000 and 2001-2022 (with patients younger than 33 years old) using the TriNetX platform.

Sofosbuvir, a nucleotide analogue, is an antiviral medication that belongs to the class of direct-acting antivirals (DAAs). It is primarily used in the treatment of chronic hepatitis C virus (HCV) infections. Sofosbuvir works by inhibiting the replication of HCV, disrupting its ability to produce RNA and effectively reducing the viral load in the body.

Hepatitis C Virus (HCV) is a blood borne pathogen that affects around 200 million individuals worldwide. Immunizations against the Hepatitis C Virus are intended to enhance T-cell responses and have been identified as a crucial component of successful antiviral therapy. Nevertheless, attempts to mediate clinically relevant anti-HCV activity in people have mainly failed, despite the vaccines present satisfactory progress.
