Hepatitis C reinfection by treatment pathway among people who inject drugs in Tayside, Scotland.

J Viral Hepat 2021 Sep 15. Epub 2021 Sep 15.

Gut Group, Division of Molecular and Clinical Medicine, School of Medicine, University of Dundee, Dundee, Scotland.

The efficacy of direct acting antivirals (DAA) provides an excellent opportunity to scale up HCV diagnosis and treatment, achieving the WHO target of HCV elimination by 2030. However, HCV reinfection among people who inject drugs (PWID) remains a concern and may impede elimination efforts. We assessed reinfection rates among PWID across six specialised treatment pathways, following DAA-based and interferon-based therapies in Tayside, Scotland. Read More

Association between ezetimibe usage and hepatitis C RNA levels in uninfected kidney transplant recipients who received hepatitis C infected kidneys.

Clin Transplant 2021 Sep 15:e14485. Epub 2021 Sep 15.

Division of Nephrology & Hypertension, Department of Medicine, University of Utah, Salt Lake City, UT, USA.

Kidney transplantation (KT) from hepatitis C virus infected(HCV+) donors to HCV negative recipients achieve excellent graft function but have relatively higher rates of post-KT co-infections presumably due to prolonged HCV viremia in transmission-and-treat approach. Ezetimibe acts as an antagonist of Niemann-Pick C1-Like 1 receptor required for HCV entry and theoretically can reduce HCV viremia. However, no data is available to examine the role of ezetimibe as a bridge therapy between KT surgery and direct acting antiviral(DAA) initiation. Read More

FADS2-dependent fatty acid desaturation dictates cellular sensitivity to ferroptosis and permissiveness for hepatitis C virus replication.

Cell Chem Biol 2021 Sep 11. Epub 2021 Sep 11.

Natural Science Division, Ochanomizu University, Bunkyō-ku, Tokyo 112-8610, Japan; Institute for Human Life Innovation, Faculty of Core Research, Ochanomizu University, Bunkyō-ku, Tokyo 112-8610, Japan.

The metabolic oxidative degradation of cellular lipids severely restricts replication of hepatitis C virus (HCV), a leading cause of chronic liver disease, but little is known about the factors regulating this process in infected cells. Here we show that HCV is restricted by an iron-dependent mechanism resembling the one triggering ferroptosis, an iron-dependent form of non-apoptotic cell death, and mediated by the non-canonical desaturation of oleate to Mead acid and other highly unsaturated fatty acids by fatty acid desaturase 2 (FADS2). Genetic depletion and ectopic expression experiments show FADS2 is a key determinant of cellular sensitivity to ferroptosis. Read More

Quantifying transmission dynamics of acute hepatitis C virus infections in a heterogeneous population using sequence data.

PLoS Pathog 2021 Sep 14;17(9):e1009916. Epub 2021 Sep 14.

MIVEGEC, CNRS, IRD, Université de Montpellier - Montpellier, France.

Opioid substitution and syringes exchange programs have drastically reduced hepatitis C virus (HCV) spread in France but HCV sexual transmission in men having sex with men (MSM) has recently arisen as a significant public health concern. The fact that the virus is transmitting in a heterogeneous population, with different transmission routes, makes prevalence and incidence rates poorly informative. However, additional insights can be gained by analyzing virus phylogenies inferred from dated genetic sequence data. Read More
