Endothelial Dysfunction and Subclinical Atheromatosis in Chronic HCV Infection. Response to DAA Agents. (C-Endys)
Personalized Medicine in HCV Chronic Infection. Endothelial Dysfunction and Subclinical Atheromatosis in Patients With HCV Infection. Characterization and Potential Reversibility With Direct Antiviral Agents.
Hypothesis: In addition to the liver deleterious effects, Chronic Hepatitis C (CHC) can cause changes in other organs highlighting the increased cardiovascular risk (CVR) through accelerated atherosclerosis, whose consequences may persist even after healing infection with new antiviral treatments. This can have major impact on the health system. Obtaining a Sustained Virological Response (SVR) with a free Interferon (IFN) antiviral treatment is probably able to reverse, at least partially, increased vascular risk induced by Hepatitis C virus (HCV) and perhaps ultimately reverse the subclinical atherosclerosis.
Aims: To study the presence of early-subclinical atherosclerotic disease (endothelial dysfunction and subclinical atherosclerosis) in patients with CHC and evaluate the influence of treatment in the short and medium term on the CVR derived. Studying these same issues but in patients with established atherosclerotic disease.

Detailed Description
Design:
Prospective interventional study.
Patients and methods:
Tracked on a population of 80 patients with CHC (estimated fibrosis F2-F3),
An evaluation of the CVR will be performed by determining biomarkers of endothelial activation and macrophage activation, measuring flow-mediated vasodilation and atherosclerotic damage.
All evaluations will take place prior (at baseline) and after antiviral treatment. Particularly, all determinations will be performed immediately before and 3, 12 and 24 months after the end of antiviral treatment.
In order to improve the diagnostic accuracy in terms of discriminating liver damage associated to Non Alcoholic Fatty Liver Disease (NAFLD) from HCV infection, the investigators will use the owl-liver® technique in all patients before and after treatment.
Sample size: Considering the primary endpoint the flow-mediated vasodilation (FMD), data have been reported on FMD of 7.6 ± 2.4% in healthy subjects and 5.1 ± 2.2% in subjects with risk factors (Dalli et al Rev Esp Cardiol 2002; 55: 928-35). Assuming these SD and a correlation coefficient of 0.3 between the two measurements, 80 patients will be needed to detect a change of 1% in vasodilation with an output of 90% and a significance level of 5%.
Variables and tasks:
Task 1. Assessment of endothelial function.
- -Vasodilation mediated by ultrasound brachial flow through the rate of increase of brachial artery diameter (d2) as compared to baseline (d1) after a ischemia time (300 mmHg) for 4 minutes (FMD = (d2-d1) / d1 (x 100).
- -Endothelial function biomarkers: ICAM-1, VCAM-1, E-selectin, P-selectin, MCP-1, angiopoietin-2, sTWEAK and ADMA.
- - Macrophage activation biomarkers: Gal-3BP, sCD163 and sCD14.
Task 2. Assessment of atherosclerotic damage. Common carotid, internal carotid and carotid bulb (bilateral) will be explored by ultrasound. The images will be electronically stored in DICOM format.
The analyzed parameters will be:
- cIMT (Carotid intima media thickness and carotid intima-media thickness) defined as the distance between the interface of the carotid lumen with arterial intima and the interface of medium with adventitia of the distal arterial wall. They will be measured on the back wall in a free-plaque area in the common carotid (cIMT CC) in the carotid bulb (cIMT -B), and internal carotid (cIMT -CI).
- Presence of carotid plaques in these territories. Plaque will be defined following the Mannheim criteria.
- Presence of atherosclerotic plaque: to distinguish between focal and diffuse thickening. In the focal plate area, maximum thickness and Gray Scale Median (GSM) will be quantified. In the diffuse thickening (IMT> 1.5 mm) only the GSM will be quantified.
Task 3. Assessment of vascular risk. Classic and emerging vascular risk assessment.
- -Study of classic risk factors: through REGICOR and Framingham Score tables. Fatty Liver Index to exclude or confirm NASH (BMI, waist circumference, triglycerides and GGT). Metabolic syndrome will be detected by the NCEP-ATPIII.
- - Study of emerging vascular risk factors, including proinflammatory factors. In this way, the investigators will analyze the plasma levels hcPCR, homocysteine, Lp(a), pentraxin 3, SAA, oxidized LDL, PON1, PCSK9 and elevated plasma levels of von Willebrand factor factor (VWF)
- - Qualitative lipoprotein changes: the total concentration of lipoprotein (VLDL, LDL, HDL) will be determined as well as their composition (total cholesterol, triglycerides, phospholipids, protein, apolipoprotein B, lipoprotein ratio / total triglyceride mass VLDL, LDL and HDL, number of VLDL, LDL and HDL, cholesterol molecules per particle and triglyceride molecules per particle).
- - Insulin resistance by HOMA.
- -HbA1c
- - Rx Thorax.

Other: Cardiovascular risk in HCV patients
Intervention: The only intervention to be carried out along the study will consist of a complete evaluation of cardiovascular risk of HCV patients both at baseline (pre-treatment) and after HCV treatment, through performing different tests (see below) Chronic HCV patients who are going to be treated with new DAAs according to current guidelines will be studied at different times before and after the end of the treatment. The participation in the study will not influence neither the indication to treat nor the treatment used. Anti-HCV regimens will be used according to clinical practice as indicated into the current guidelines |
Cardiovascular risk assessement (through Flow-mediated vasodilatation "FMV", measurement of endothelial function biomarkers, carotid ultrasound, etc.) This is a prospective study. The only intervention planned will consist of performing different tests that define the individual cardiovascular risk. These tests will be carried out on a single group cohort at different times. Notwithstanding, the investigators will record the exposure to DAA to assess any change in CVR. Anti-HCV regimens will be used according to clinical practice as indicated into the current guidelines (1) (1)European Association for Study of Liver. EASL Recommendations on Treatment of Hepatitis C 2015. J Hepatol. 2015 Jul;63(1):199-236. doi: 10.1016/j.jhep.2015.03.025. Epub 2015 Apr 21. PubMed PMID: 25911336. |
