| Summary: | The presented method of integrated assessment of liver fibrosis degree based on the comparison of the data obtained in the study of electric and viscoelastic parameters of erythrocytes by the dielectrophoresis method using the electro-optical system of the detection cells and method for indirect elastometry. A high degree of comparability of the results of the above-described methods was established when the degree of fibrosis F 2-4 in the absence of marked cytolysis, cholestasis, inflammatory syndrome, metal overload. It is shown that parallel using the methods of dielectrophoresis and indirect elastography is needed in the presence of a rise of transaminases, gammaglutamyltranspeptidase more than 5 norms, expressed dysproteinemia, syndromes of iron overload, copper to increase the accuracy in determining the degree of liver fibrosis. The evaluation of dynamics of changes of the degree of fibrosis during antiviral therapy is more accurate by the method of indirect elastometry, and the method of dielectrophoresis is preferable in the treatment of nonalcoholic fatty liver disease. In cases of restrictions on the use of the method for indirect elastography (marked obesity, ascites, cholelithiasis, pregnancy, presence of pacemaker, prosthesis) to determine the degree of fibrosis the method of dielectrophoresis of red blood cells can be used. Simultaneous use of both methods (using the identified discriminatory values) allows to reduce or to neutralize their disadvantages, dependence on associated syndromes, to expand the possibilities of their application, to improve the diagnostic accuracy in determining each of the degrees of liver fibrosis. Integrated application of both methods — indirect elastography and dielectrophoresis of red blood cells — for determining the degree of liver fibrosis allows to achieve high levels of sensitivity (88.9 percent) and specificity (100 percent) compared to the “gold standard” — biopsy of the liver. |
