Стадия заболевания у всех пациентов подтверждалась морфологическим исследованием с определением индекса гистологической активности (ИГА) и стадии фиброза (F). Эти данные сопоставлялись с данными неинвазивной оценки фиброза печени – результатами биохимических тестов (коэффициенты де Ритиса, APRI), ультразвуковых исследований с допплерографией, видеоденситометрией, эластометрией (ЭМ) с помощью аппарата FibroScan («EchoSens», Франция).Результаты. Выявлены достоверные различия в показателях эластичности ткани печени в зависимости от стадии фиброза (F0, F1, F2, F3, F4) – р&lt;0,001 при HCV­инфекции и р&lt;0,05 при HBV­инфекции. Чувствительность и специфичность ЭМ составила от 0,8 до 0,99 (площадь под ROC­кривой). Проведен канонический дискриминантный анализ с составлением территориальной карты, позволяющий, используя данные ультразвукового исследования, отнести стадию фиброза к легкой, умеренной и тяжелой.Выводы. Применение неинвазивных методов оценки фиброза целесообразно при первичном обследовании HCV RNA­ и HBV DNA­позитивных больных. Высокая диагностическая точность позволяет сегодня считать эластометрию методом выбора диагностики фиброза печени при ее диффузных поражениях.</p></abstract><trans-abstract xml:lang="en"><sec><title>Aim of investigation</title><p>Aim of investigation.

Overall 188 HCV RNApositive patients and 61 HBV DNA-positive were investigated. The stage of disease in all patients was verified by morphological study with assessment of histological activity index (HAI) and stage of fibrosis (F). These data were compared to data of non-invasive evaluation of liver fibrosis – i.e. results of biochemical tests (de Ritis coefficients, APRI), ultrasound investigation with Doppler ultrasonography, videodensitometry, elastometry (EM) by FibroScan device («EchoSens», France).</p></sec><sec><title>Results</title><p>Results. Significant differences in scores of liver tissue elasticity in relation to stage of fibrosis (F0, F1, F2, F3, F4) – р&lt;0,001 were revealed at HCV-infection and р&gt;&lt;0,05 at HBV-infection. EM sensitivity and specificity ranged from 0,8 to 0,99 (area under the ROC-curve). Canonical discriminant analysis with drawing of territorial map, that allow to define fibrosis stage as mild, moderate or severe, using data of ultrasound investigation, was carried out. Conclusions. Application of non-invasive methods of evaluation of fibrosis is reasonable at primary investigation of HCV RNA-and HBV DNA-positive patients. Today high diagnostic accuracy allows to consider elastometry as a method of choice in diagnostics of liver fibrosis in diffuse liver diseases. &gt;&lt;0,001 were revealed at HCV-infection and р&lt; 0,05 at HBV-infection.
