BACKGROUND: Donors with hepatitis C (HCV) viremia are rarely utilized for orthotopic heart transplantation (OHTx) due to post-transplant risks. New, highly effective HCV antivirals may alter the landscape. METHODS: An adult patient unsuitable for bridging mechanical support therapy accepted a heart transplant offer from a donor with HCV viremia. Upon daily logarithmic rise in HCV viral load and adequate titers to ensure successful genotyping, once daily sofosbuvir 400 mg / velpatasvir 100 mg (Epclusa) was initiated empirically pending HCV genotype (genotype 3a confirmed after initiation of therapy)...

BACKGROUND: Statins are a class of therapeutics used to regulate serum cholesterol and reduce the risk of heart disease. Although statins are highly effective in removing cholesterol from the blood, their consumption has been linked to potential adverse effects in some individuals. The most common events associated with statin intolerance are myopathy and increased risk of developing type 2 diabetes mellitus. However, the pathological mechanism through which statins cause these adverse effects is not well understood...

OBJECTIVES: Excessive consumption of added sugars in the human diet has been associated with obesity, type 2 diabetes (T2D), coronary heart disease (CHD) and other elements of the metabolic syndrome. Recent studies have shown that non-alcoholic fatty liver disease (NAFLD) is a critical pathway to metabolic syndrome. This model assesses the health and economic benefits of interventions aimed at reducing intake of added sugars. METHODS: Using data from US National Health Surveys and current literature, we simulated an open cohort, for the period 2015-2035...

BACKGROUND & AIMS: Patients with hepatitis C virus (HCV)-associated cirrhosis and clinical significant portal hypertension (CSPH, hepatic venous pressure gradient [HVPG] 10 mmHg or greater), despite achieving sustained virological response (SVR) to therapy, remain at risk of liver decompensation. We investigated hemodynamic changes following SVR in patients with CSPH and whether liver stiffness measurements (LSMs) can rule out the presence of CSPH. METHODS: We performed a multicenter prospective study of 226 patients with HCV-associated cirrhosis and CSPH who had SVR to interferon-free therapy at 6 Liver Units in Spain...

REVIEW
Nicolas Goossens, Francesco Negro
Hepatitis C virus (HCV) infection is a prevalent condition associated with numerous extrahepatic manifestations. Epidemiologic studies have found that HCV is associated with increased cardiovascular morbidity and mortality, in particular with carotid atherosclerosis, cerebrovascular events, and coronary heart disease. The mechanisms involved encompass a chronic systemic inflammatory state, insulin resistance, and a potential, direct infection of the vascular endothelium. Sustained virologic response with interferon-based regimens is associated with reduced cardiovascular events, although this must be validated with newer direct-acting antivirals...

Previous studies have grouped all donors positive for hepatitis C virus (HCV) antibody (Ab). Only recently has donor HCV nucleic acid testing (NAT) become routine, and the impact of Ab and NAT status on organ utilization is unknown. Using the United Network for Organ Sharing database, we identified 9290 donors from 2015 to 2016 for whom both HCV Ab and NAT data were available and compared organ utilization by HCV status. Overall, 93.8% of donors were Ab negative and NAT negative (Ab-NAT-), 0.15% were Ab negative and NAT positive, 1...

BACKGROUND AND AIMS: Oxidative modification of lipoproteins is a crucial step in atherosclerosis development. Isotopic-reinforced polyunsaturated fatty acids (D-PUFAs) are more resistant to reactive oxygen species-initiated chain reaction of lipid peroxidation than regular hydrogenated (H-)PUFAs. We aimed at investigating the effect of D-PUFA treatment on lipid peroxidation, hypercholesterolemia and atherosclerosis development. METHODS: Transgenic APOE*3-Leiden...

Tanshinone IIA (TSA), a pharmacologically active component isolated from Danshen, may prevent cardiovascular diseases due to its anti-inflammatory, anti-oxidative, and anti-adipogenic effects. Porphyromonas gingivalis, a major periodontal pathogen, may contribute to the progression of atherosclerosis. Here, we studied the effects of TSA on atherosclerosis in ApoE(-/-) mice with P. gingivalis infection. Eight-week-old ApoE(-/-) mice were randomized to (a) phosphate-buffered saline (PBS), (b) P. gingivalis, and (c) P...

BACKGROUND: Until recently, transplantation from hepatitis C-positive donors was relatively contraindicated as eradication of active hepatitis C previously required an interferon-based regimen that has been associated with rejection in solid organ transplantation. New interferon-free treatment regimens for hepatitis C have fewer adverse events and higher cure rates than interferon-based regimens. Interferon-free regimens have been shown to be safe in the liver transplantation literature, but little is known about the safety and efficacy of treatment in heart transplantation...
