The presence of hepatitis C virus (HCV) in normal cervical smears (CS) obtained from 22 HCV-seropositive and 50 HCV-seronegative patients was assessed by reverse-transcriptase-polymerase chain reaction (RT-PCR). The presence of HCV in serum was established by use of enzyme-linked immunosorbent assay, Western blot test, and RT-PCR. HCV was detected in 36.4% (n=8) of CS cells recovered from 22 HCV-seropositive patients, but not in CS samples obtained from 50 HCV-seronegative patients. Furthermore, cells from the CS of 2 seropositive/smear-positive patients and 1 seropositive/smear-negative patient were isolated; HCV RNA was detectable in the cervical lymphocytes of the 2 smear-positive patients, but not in epithelial cells or granulocytes. HCV RNA is detectable in the CS of some HCV-seropositive women. The clinical importance of these data requires further study.

Background: Direct acting antivirals (DAAs) have demonstrated remarkable efficacy, in achieving hepatitis C viral (HCV) elimination rates higher than 90%. One particular concern associated with treatment failure is the emergence of resistance associated substitutions (RASs) in the genome. The occurrence of RASs highlights the adaptability and resilience of the HCV.

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.
