Диагностика хронических диффузных заболеваний печени представляет одну из актуальных проблем современной гепатологии. Cегодня ультразвуковая сдвиговая эластография дает возможность провести объективную количественную оценку упругости печени при фиброзе и определить его выраженность. Однако оценка влияния неалкогольной жировой болезни печени (НАЖБП) на количественные показатели эластометрии у пациентов с фиброзом до настоящего  времени остается предметом дискуссий.  </p></sec><sec><title>Цель исследования</title><p>Цель исследования: изучение на основании верифицированных патоморфологических данных влияния  НАЖБП на результаты сдвиговой эластографии.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведен ретроспективный  анализ результатов обследования 137 пациентов с хроническими диффузными заболеваниями печени, госпитализированных в НИИ–ККБ №1 г. Краснодара в 2015– 2016 гг. для морфологической верификации процесса и уточнения диагноза. В 1-ю группу вошло 117 пациентов с отсутствием жировых изменений в паренхиме. Во 2-ю группу (n = 20) были включены больные со стеатозом печени. В работе использована ультразвуковая  диагностическая система Aixplorer (Франция). Всем  пациентам выполнялась двухмерная сдвиговая волновая эластометрия (2DSWE) с определением упругости печени. Результаты распределены по шкале Metavir.</p></sec><sec><title>Результаты</title><p>Результаты. У больных 1-й группы (без стеатоза) при проведении ROC-анализа были получены пороговые значения упругости, при которых диагностическая эффективность метода сдвиговой эластографии в определении стадии фиброза (по Metavir) оказалась наиболее  оптимальной: для F2 &gt; 6,8 кПа (чувствительность 85,7%,  специфичность 52,9%, AUROC 0,684); для F3 &gt; 8,5 кПа  (чувствительность 91%, специфичность 57,1%, AUROC  0,745); для F4 &gt; 14 кПа (чувствительность 95,7%, специфичность 52,2%, AUROC 0,791). Установлено, что наличие стеатоза увеличивало упругость ткани печени. Так,  в подгруппе sF0 (со стеатозом) отмечался достоверный  рост модуля Юнга до Ме = 11,2 кПа (95% CI 7,3–17,5) по сравнению с Ме = 6,1 кПа (95% CI 5,4–9,6) в подгруппе F0 (без стеатоза) (P = 0,0168, AUROC = 0,741). В подгруппе sF0+sF1 (со стеатозом) упругость печени также оказалась увеличенной до Ме = 9,95 кПа (95% CI 6,8–13,0)  по сравнению с Ме = 6,65 кПа (95% CI 5,6–9,5) в подгруппе F0+F1 (без стеатоза) (P = 0,0295, AUROC = 0,707).  Это увеличение составило 83,6 и 49,6% соответственно.</p></sec><sec><title>Заключение</title><p>Заключение. Выполненное исследование подтвердило эффективность метода сдвиговой эластографии в оценке взаимосвязи показателей жесткости паренхимы печени с морфологической стадией фиброза,  а также способствовало доказательному утверждению о влиянии стеатоза на упругость печени. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim</title><p>The aim: to study of the effect of NAFLD on the results of shear elastography (based on the results of liver biopsy).  </p></sec><sec><title>Materials and methods</title><p>Materials and methods. We have performed outcome analysis in 137 patients, treated from 2015 to 2016. All patients had chronic diffuse liver diseases and were hospitalized for morphological evaluation and diagnosis clarification. Group 1 (n = 117) with no fat changes in the liver parenchyma. Group 2 (n = 20) with steatosis of the liver.  In our work, we used: scanner Aixplorer (France). All patients underwent shear wave elastography (2DSWE) with the study of the quantitative index of stiffness of liver tissue, staging the results on the Metavir scale.</p></sec><sec><title>Results</title><p>Results. In the 1st group of patients (without steatosis), in the ROC analysis, cutoff values of elasticity were obtained, the diagnostic efficiency of the Metavir stage of fibrosis was the most optimal: for F2 &gt; 6.8 kPa (sensitivity 85.7, specificity 52, 9, AUROC 0.684); For F3 &gt; 8.5 kPa (sensitivity 91, specificity 57.1, AUROC 0.745); For F4 &gt; 14 kPa (sensitivity 95.7, specificity 52.2, AUROC 0.791). It was found, that the presence of steatosis significantly increases the elasticity of the liver tissue. So, in the subgroup sF0 (with steatosis) was a significant increasing of young's module Ме = 11,2 kPa (95% CI 7,3–17,5) compared to Ме = 6,1 kPa (95% CI 5,4– 9,6) in the subgroup F0 (without steatosis) (P = 0,0168, AUROC = 0,741) and up to Ме=9,95 kPa (95% CI 6,8–13,0) in the subgroup sF0 + sF1 (with steatosis) compared with Ме=6,65 kPa (95%CI 5,6–9,5) of the subgroup F0 + F1 (without steatosis) (P = 0.0295, = 0.707). This increase was, respectively, 83,6% and 49.6%  </p></sec><sec><title>Сonclusions</title><p>Сonclusions. This study confirmed the effectiveness of the shear wave elastography method in assessing the relationship between stiffness parameters and the morphological fibrosis of the liver parenchyma and also contributed to the final confirmation of the effect of steatosis on  liver stiffness.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фиброз печени</kwd><kwd>стеатоз печени</kwd><kwd>НАЖБП</kwd><kwd>эластография сдвиговой волной</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hepatic fibrosis</kwd><kwd>steatosis</kwd><kwd>NAFLD</kwd><kwd>shear wave elastography</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Калинин Е.Ю., Щербаков П.Ю., Распереза Д.В.
