The functional state of endothelium at chronic hepatitis C
Abstract
Aim of investigation. To study the functional state of endothelium at patients with chronic hepatitis C (CHC).
Materials and methods. Forty patients with CHC in relapse phase were investigated. In all cases activity of inflammatory process was assessed, indication of НСV RNA was carried out and assessment of HCV genotype in blood serum, quantity of desquamated endotheliocytes (DEC), level of nitric oxide (NO), endothelin-1 (Et-1) and functional activity of von Willebrand factor (vWF) in blood plasma was investigated.
Results. At patients of CHC elevation of DEC quantity has been registered in comparison to group of generally healthy persons (5,9±1,18·104/l and 3,02±1,2·104/l respectively, р=0,001), decrease of NO level (18,6±3,02 and 29,43±3,34 mcmol/l, р=0,001), increase of Et-1 concentration (0,7±0,21 and 0,3±0,13 fmol/l, р=0,0001) and vWF functional activity (102,1±4,75 and 80,11±2,77%, р=0,003) in blood plasma. At evaluation of dynmics of endothelial disorders during combined antiviral the rapy (AVT) studied parameters in the basic group of patients (n=10) underwent significant changes: DEC amount decreased by 35,5% from initial value, NO level increased by 35%, concentration Et-1 decreased by 63%, vWF functional activity decreased by 16% from an initial level that testifies decrease of damage activity and dysfunction of endothelium.
Conclusions. At CHC there are signs of damage and dysfunction of endothelium. Combined AVT by Reaferon in combination to ribavirin at such patients is accompanied by significant improvement of endothelium functional parameters.
