В настоящее время «золотым стандартом» дифференциальной диагностики болезни Иценко–Кушинга является катетеризация нижних каменистых синусов с забором проб венозной крови и определением уровня адренокортикотропного гормона (АКТГ). Данные литературы свидетельствуют о широкой вариабельности чувствительности и специфичности катетеризации нижних каменистых синусов в пределах 85–100 и 67–100 % соответственно, что может приводить к ошибочной диагностике источника гиперпродукции АКТГ и, как следствие, неверному и несвоевременному лечению.</p><p>Цель исследования – улучшение результатов дифференциальной диагностики болезни Иценко–Кушинга путем применения билатеральной одномоментной катетеризации кавернозных и нижних каменистых синусов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Когортное одноцентровое ретро- /проспективное исследование с участием 70 пациентов с подтвержденным АКТГ-зависимым гиперкортицизмом. С целью дифференциальной диагностики выполняли расчет ряда показателей: центрально-периферический градиент, пролактин-нормализованное отношение АКТГ, градиент успешности катетеризации. Оценку результатов катетеризации проводили путем сравнения с данными магнитно-резонансной томографии гипофиза с контрастным усилением и интраоперационными данными.</p></sec><sec><title>Результаты</title><p>Результаты. Исследование центрально-периферического градиента показало необходимость его оценки одновременно на уровне кавернозных и нижних каменистых синусов. Такой подход позволяет существенно повысить чувствительность и специфичность применяемого градиента – до 93,1 и 85,7 % соответственно. Пролактин-нормализованное отношение АКТГ является предиктором 2‑й линии в дифференциальной диагностике болезни Иценко– Кушинга с чувствительностью и специфичностью, достигающими 94,7 и 28,6 % соответственно. Градиент успешности катетеризации отражает возможные гемодинамические особенности конкретного синуса, не служит показателем корректного позиционирования микрокатетеров в сосудистом русле.</p></sec><sec><title>Выводы</title><p>Выводы. Билатеральная одномоментная катетеризация кавернозных и нижних каменистых синусов является эффективным методом дифференциальной диагностики болезни Иценко–Кушинга и эктопического АКТГ-зависимого синдрома.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Currently, the “gold standard” of differential diagnosis of Cushing’s disease is inferior petrosal sinus sampling and measurement of the adenocorticotropic hormone (ACTH) level. The studied literature data indicate a wide variability in the sensitivity and specificity of inferior petrosal sinus sampling in the range of 85–100 and 67–100 %, respectively, which can lead to an erroneous diagnosis of the source of ACTH hyperproduction and, as a consequence, to incorrect and untimely treatment.</p></sec><sec><title>Aim</title><p>Aim.To improve the results of differential diagnosis of Cushing»s disease by using bilateral simultaneous sampling of the cavernous and inferior petrosal sinuses.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Cohort single-center retro/prospective study of 70 patients with confirmed ACTH-dependent Cushing’s syndrome. For the purpose of differential diagnosis, a number of indicators were calculated: central-peripheral ratio, prolactin-normalized ACTH ratio, successful catheterization. Sampling results were evaluated in comparison with contrast-enhanced pituitary magnetic resonance imaging data and intraoperative data.</p></sec><sec><title>Results</title><p>Results. The study of the central-peripheral ratio showed the need to assess it simultaneously at the level of the cavernous and inferior petrosal sinuses. This approach makes it possible to significantly increase the sensitivity and specificity of the applied gradient to 93.1 and 85.7 %, respectively. Prolactin-normalized ACTH ratio is a second line predictor in the differential diagnosis of Cushing’s disease with sensitivity and specificity reaching 94.7 and 28.6 %, respectively. The gradient of successful catheterization is a reflection of possible hemodynamic features of a particular sinus, does not serve as an indicator of the correct positioning of microcatheters in the vascular bed.</p></sec><sec><title>Conclusion</title><p>Conclusion. Bilateral simultaneous sampling of the cavernous and inferior petrosal sinuses is an effective method of differential diagnosis of Cushing’s disease and ectopic ACTH-dependent syndrome.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Иценко–Кушинга</kwd><kwd>центрально-периферический градиент</kwd><kwd>пролактин-нормализованное отношение адренокортикотропного гормона</kwd><kwd>градиент успешности катетеризации</kwd><kwd>катетеризация кавернозных и нижних каменистых синусов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Cushing’s disease</kwd><kwd>central-peripheral ratio</kwd><kwd>prolactin-normalized adenocorticotropic hormone ratio</kwd><kwd>successful catheterization</kwd><kwd>cavernous and inferior petrosal sinuses sampling</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">Fleseriu M., Auchus R., Bancos I. et al.
