The main variants of AAV are granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA).</p> <p><bold>Aims</bold> — to define the prevalence of pulmonary involvement in AAV patients and describe its computed tomography (CT)-patterns.</p> <p><bold>Methods.</bold> A retrospective study was conducted. The study included patients with GPA and MPA. The diagnosis was established in accordance with the American College of Rheumatology (1990) criteria of GPA or the Chapel-Hill (2012) conference AAV definitions, as well as the classification criteria of GPA and MPA of the American College of Rheumatology and the European Alliance of Associations for Rheumatology (2022). All patients underwent chest CT. The primary endpoint was lung involvement, as determined by the results of a clinical and instrumental examination.</p> <p><bold>Results.</bold> 243 patients (median age of onset 49.0 (35.0; 59.0); 167 (68.7%) women) with AAV were included in the study, including 171 with GPA and 72 with MPA. Lung damage was established in 175 (72.0%) patients (121 (70.8%) in GPA and 54 (75.0%) in MPA). The following variants of pulmonary involvement in AAV were registered: parenchymal infiltrates — 103 (58.9%); alveolar hemorrhage — 33 (18.9%); nodular disease — 58 (33.1%); cavities — 28 (16.0%); subclinical interstitial lung disease (ILD) — 43 (24.6%); ILD — 8 (4.6%); signs of fibrosis — 135 (77.1%); bronchiectasis — 24 (13.7%); and pleural effusion — 3 (1.7%). In GPA patients, cavities were more prevalent (p &lt; 0.001), so alveolar hemorrhage was in MPA (p &lt; 0.001). PR3-ANCA (OR: 3.25; 95% CI: 1.40–7.49) and general symptoms (fever, weight loss) (OR: 2.41; 95% CI: 1.28–4.54) were associated with pulmonary damage according to the logistic regression model.</p> <p><bold>Conclusions. </bold>Pulmonary involvement in AAV is frequent. Among 243 patients with MPA and GPA who underwent a CT scan of the chest, 72% had lung abnormalities. These findings may have important implications for the diagnosis and management of AAV lung manifestations.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Поражение легких при васкулитах, ассоциированных с антинейтрофильными цитоплазматическими антителами (АНЦА-ассоциированных васкулитах, ААВ), представляет актуальную клиническую проблему в связи с влиянием на прогноз заболевания. Основными нозологическими вариантами ААВ являются гранулематоз с полиангиитом (ГПА), микроскопический полиангиит (МПА) и эозинофильный гранулематоз с полиангиитом (ЭГПА).</p> <p><bold>Цель исследования</bold> — определить частоту и структуру поражения легких при ААВ.</p> <p><bold>Методы.</bold> В ретроспективное исследование включали пациентов с ГПА и МПА, диагноз которых устанавливали в соответствии с критериями Американской коллегии ревматологов (1990 г.), определениями и номенклатурой, принятыми на конференции в Чапел-Хилл (2012 г.), а также классификационными критериями ГПА и МПА Американской коллегии ревматологов и Европейского альянса ревматологических ассоциаций (2022 г.). Всем пациентам была выполнена компьютерная томография легких. Исследование АНЦА осуществлялось методом иммуноферментного анализа. Основным оцениваемым исходом было поражение легких, установленное по результатам клинико-инструментального обследования.</p> <p><bold>Результаты.</bold> В исследование включено 243 пациента с ААВ. Поражение легких выявлено у 175 (72,0%) из них, в том числе у 121 (70,8%) из 171 пациента с ГПА и у 54 (75,0%) из 72 пациентов с МПА. Были зарегистрированы следующие клинико-рентгенологические варианты поражения легких при ААВ: инфильтративное поражение — 103 (58,9%) пациента; диффузное альвеолярное кровотечение (ДАК) — 33 (18,9%); узловые образования — 58 (33,1%); полости распада — 28 (16,0%); субклиническое интерстициальное заболевание легких (ИЗЛ) — 43 (24,6%); определенное ИЗЛ — 8 (4,6%); фиброзные изменения — 135 (77,1%); бронхоэктазы — 24 (13,7%); плевральный выпот — 3 (1,7%) пациента. У пациентов с ГПА чаще определялись полости деструкции легочной ткани (р &lt; 0,001), а у пациентов с МПА — развитие ДАК (р &lt; 0,001). По данным многофакторного регрессионного анализа наличие АНЦА к протеиназе-3 (ОШ — 3,25; 95%-й ДИ: 1,40–7,49) и конституциональных симптомов (ОШ — 2,41; 95%-й ДИ: 1,28–4,54) ассоциировалось с поражением легких.</p> <p><bold>Заключение.</bold> Поражение легких выявлено у 72,0% пациентов с ААВ и с одинаковой частотой встречалось при ГПА и МПА, хотя варианты его отличались при двух типах ААВ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>anti-neutrophil cytoplasmic antibody-associated vasculitis</kwd><kwd>pulmonary</kwd><kwd>X-ray computed tomography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>АНЦА-ассоциированные васкулиты</kwd><kwd>поражение легких</kwd><kwd>компьютерная томография</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Jennette JC, Falk RJ, Bacon PA, et al. 2012 revised International Chapel Hill Consensus Conference Nomenclature of Vasculitides.
