Одной из наиболее актуальных проблем ультразвуковой сдвиговой эластометрии печени является отсутствие отчетливых цифровых дифференциально-диагностических критериев наличия и выраженности фиброза при воспалении.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: оценить возможность нового ультразвукового параметра – крутизны дисперсии скорости сдвиговых волн (shear wave dispersion slope, SWDS) в решении этой проблемы.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 166 пациентов с различной патологией печени. В зависимости от отсутствия или наличия фиброза, а также воспалительных изменений в печени (по данным биопсии и серологических исследований крови) обследованные разделены на 3 группы. Контрольная группа состояла из 10 здоровых доноров. Измерения скорости сдвиговых волн (SWS), крутизны дисперсии скорости сдвиговых волн (SWDS) и оценку аттенуации ультразвука (ATI) в печени проводили на ультразвуковой диагностической системе Canon Medical Aplio i800 (Токио, Япония) с помощью стандартного конвексного преобразователя 1–8 MГц.</p></sec><sec><title>Результаты</title><p>Результаты. Показатели SWS, SWDS и ATI (медиана и 95% ДИ) в контрольной группе составили 1,2 (1,1–1,6) м/с, 10,1 (9,7–14,3) м/с/кГц и 0,54 (0,41–0,63) дБ/см/МГц соответственно. Исследование основной группы показало, что между SWS и SWDS существует тесная корреляция (Spearman's rho = 0,74). При этом у пациентов группы с воспалением имели место достоверно (p &lt; 0,01) более высокие значения SWDS по сравнении с контрольной группой и группой без воспаления –16,4 (15,3–17,9) м/с/кГц против 10,1 (1,7–14,3) м/с/кГц и 12,7 (12,1–14,3) м/с/кГц соответственно. У больных подгруппы с фиброзом, но без воспаления, также было отмечено достоверное (p &lt; 0,01) повышение SWDS с 12,0 (11,4–12,8) м/с/кГц при F0–1 до 16,5 (12,9–20,3 ) м/с/кГц при F3–4 по МЕТАВИР.</p></sec><sec><title>Заключение</title><p>Заключение. Использование абсолютных значений SWDS не способствовало достижению цели настоящего исследования – обнаружению отчетливых критериев дифференциальной диагностики наличия и выраженности фиброза печени у больных с гепатитом. Тем не менее, результаты исследования дают основание сделать достаточно уверенное заключение о том, что оценка взаимотношений SWDS и SWS с помощью формулы бинарной логистической регрессии (logit(p) = 0, 4152 SWDS (м/с/кГц) – 0,1344 SWS (м/с) – 6,5115) может стать ценным дополнительным методом ультразвуковой диагностики воспалительных изменений в печени.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: one of the most pressing problems of ultrasound shear wave elastometry of the liver is the lack of distinct digital differential diagnostic criteria for the presence and severity of fibrosis in inflammation.</p></sec><sec><title>Purpose</title><p>Purpose. To evaluate the possibility of a new ultrasonic parameter – the shear wave dispersion slope (SWDS) in solving this problem.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 156 patients with various liver pathologies were examined. Depending on the absence or presence of fibrosis, as well as inflammatory changes in the liver (according to biopsy and serological blood tests), the examined patients were divided into three groups. The control group consisted of 10 healthy donors. Measurements of the shear wave velocity (SWS), shear wave dispersion slope (SWDS) and the assessment of ultrasound attenuation (ATI) in the liver were performed using the Canon Medical Aplio i800 ultrasound diagnostic system (Tokyo, Japan) using a standard convex transducer.</p></sec><sec><title>Results</title><p>Results. The indicators of SWS, SWDS and ATI (Median and 95% CI) in the control group were Me 1.2 (95% CI 1.1–1.6) m/s, Me 10.1 (95% CI 9.7–14.3) m/s/kHz and Me 0.54 (95% CI 0.41–0.63) dB/cm/MHz, respectively. The study of the main group showed that there is a close correlation between SWS and SWDS (Spearman's rho = 0.74). At the same time, patients in the subgroup with inflammation had significantly (p &lt; 0.01) higher SWDS values compared with the control group and the subgroup without inflammation – Me 16.4 (95% CI 15.3–17.9) m/s/kHz versus Me 10.1 (95% CI 9.7–14.3) m/s/kHz and Me 12.7 (95%CI 12.1–14.3) m/s/kHz. In patients of the subgroup with fibrosis, but without inflammation, there was also a significant (p &lt; 0.01) increase in SWDS from Me 12,0 (95% CI 11.4–12.8) m/s/kHz at F0-1 to Me 16,5 (95% CI 12.9–20.3) m/s/kHz at F3–4 METAVIR.</p></sec><sec><title>Conclusion</title><p>Conclusion. The use of absolute SWDS values did not contribute to the achievement of the purpose of this study – the detection of criteria for the differential diagnosis of the presence and severity of liver fibrosis in patients with hepatitis. Nevertheless, the results of the study provide grounds for making a fairly confident conclusion that the assessment of the relationship between SWDS and SWS using the binary logistic regression formula (logit(p) = 0, 4152 SWDS (м/с/кГц) – 0,1344 SWS (м/с) – 6,5115) can become a valuable additional method for ultrasound diagnostics of inflammatory changes in the liver.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фиброз печени</kwd><kwd>воспаление печени</kwd><kwd>скорость сдвиговых волн (SWS) в печени</kwd><kwd>дисперсия скорости сдвиговых волн (SWDS) в печени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liver fibrosis</kwd><kwd>inflammation of the liver</kwd><kwd>the velocity of shear waves (SWS) in the liver</kwd><kwd>the dispersion slope of shear wave velocity (SWDS) in the liver</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">Зубарев А.В., Гажонова В.Е., Гусакова Е.В., Чуркина С.О., Миронова Е.В.
