Диагностика гиперчувствительного пневмонита (ГП) при помощи высокоразрешающей компьютерной томографии (ВРКТ) представляет собой непростую задачу. К наиболее сложным аспектам заболевания относятся дифференциальная диагностика его фибротического (фГП) и нефибротического (нфГП) фенотипов, а также их разграничение с обычной интерстициальной пневмонией (ОИП) при идиопатическом легочном фиброзе. Определение фиброзных изменений на ранней стадии развития позволяет существенно ускорить начало антифибротической терапии и улучшить прогноз заболевания.</p></sec><sec><title>Цель</title><p>Цель: выявить ключевые признаки при ВРКТ для достоверного разделения фГП и нфГП, провести дифференциальную диагностику между фГП и ОИП.</p></sec><sec><title> Материал и методы</title><p> Материал и методы. Проведен ретроспективный анализ данных 73 пациентов с морфологически верифицированным диагнозом ГП, у которых была выполнена ВРКТ. При этом у 21 больного определен нфГП, у 52 – фГП. Группу сравнения составили 24 пациента с типичной рентгенологической картиной ОИП. Анализ выявленных при ВРКТ изменений осуществляли качественными и полуколичественными методами. Достоверность качественных различий выраженности признака оценивали на основании точного теста Фишера, полуколичественных различий – с помощью теста Манна–Уитни.</p></sec><sec><title>Результаты</title><p>Результаты. Проведенный анализ исследований ВРКТ показал, что наличие и выраженность определенных ВРКТ-признаков достоверно различаются между выделенными группами пациентов в качественном и/или полуколичественном выражении. В случаях с ГП распределение изменений было в основном равномерным и диффузным, без четкого преобладания в отдельных долях. При ОИП имело место диффузное краниокаудальное распределение, причем в аксиальной плоскости изменения носили преимущественно субплевральной характер.</p></sec><sec><title>Заключение</title><p>Заключение. На основании результатов исследования можно предположить, что фГП достоверно отличается от нфГП по таким признакам, как наличие и степень выраженности симптомов матового стекла, сотового лeгкого, ретикулярных изменений и тракционных бронхоэктазов. При сравнении групп фГП и ОИП отличительными признаками фГП являлись наличие центрилобулярных очагов, симптома мозаичной плотности, а также диффузное аксиальное распределение признаков.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Diagnosis of hypersensitivity pneumonitis (HP) using high-resolution computed tomography (HRCT) is not an easy task. The most difficult aspects of the disease include differential diagnosis of its fibrotic (fHP) and non-fibrotic (nfHP) phenotypes, as well as their differentiation from usual interstitial pneumonia (UIP) in idiopathic pulmonary fibrosis. The determination of fibrous changes at an early stage of development can significantly accelerate the beginning of antifibrotic therapy and improve the prognosis.</p></sec><sec><title>Objective</title><p>Objective: to identify key HRCT signs for reliable differentiation of fHP and nfHP, to carry out differential diagnostics between fHP and UIP.</p></sec><sec><title>Material and methods</title><p>Material and methods. The data of 73 patients with morphologically verified HP, in whom HRCT had been performed, were retrospectively analysed. In 21 patients, nfHP was determined, and in 52 patients fHP was identified. The comparison group consisted of 24 patients with a typical radiological UIP pattern. The analysis of the changes detected during HRCT was carried out by qualitative and semi-quantitative methods. The significance of qualitative differences in a sign manifestation was assessed by Fisher’s exact test, semi-quantitative differences were evaluated using Mann–Whitney test.</p></sec><sec><title>Results</title><p>Results. The results of the study allow to assume, that the presence and degree of manifestation of certain HRCT signs significantly differ between the selected groups of patients in qualitative and/or semi-quantitative terms. In cases of НP, the distribution of changes was mostly uniform and diffuse, with no clear predominance in certain lobes. In UIP, diffuse craniocaudal distribution took place, and in the axial plane, the changes were mainly subpleural in nature.</p></sec><sec><title>Conclusion</title><p>Conclusion. Based on the results of the study, it can be assumed that fHP significantly differs from nfHP in such features as the presence and degree of manifestation of ground glass and honeycombing symptoms, reticular changes and traction bronchiectases. When comparing the fHP and UIP groups, the distinctive signs of fHP were centrilobular nodules, mosaic pattern, as well as diffuse axial sign distribution.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>высокоразрешающая компьютерная томография легких</kwd><kwd>гиперчувствительный пневмонит</kwd><kwd>интерстициальные заболевания легких</kwd><kwd>обычная интерстициальная пневмония</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-resolution pulmonary computed tomography</kwd><kwd>hypersensitivity pneumonitis</kwd><kwd>interstitial lung  diseases</kwd><kwd>usual interstitial pneumonia</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">Raghu G, Remy-Jardin M, Ryerson CJ, et al.
