Проведен анализ клинического случая генерализованного ассоциированного антинейтрофильных цитоплазматических антител васкулита у подростка 16 лет. Случай демонстрирует сложность и длительность диагностического поиска, обусловленные полиморфной и постепенно развивающейся симптоматикой (поражение органов оториноларингологии, суставов, почек, глаз). Длительность болезни на момент постановки диагноза превышала 12 месяцев. Отсроченная диагностика увеличивает риск необратимых органных повреждений, что определяет серьезный долгосрочный прогноз даже при успешном начальном ответе на лечение. Таким образом, повышение осведомленности педиатров о клинических особенностях ассоциированных антинейтрофильных цитоплазматических антител васкулитов является ключевым фактором для улучшения исходов у данной категории пациентов.</p></abstract><trans-abstract xml:lang="en"><p>The article aims to describe the pediatric challenges in treating patients having granulomatosis with polyangiitis (GPA) and emphasize the importance of using a multidisciplinary approach in managing multiple organ pathology of uncertain origin. To achieve this goal, the authors analyze a clinical case of generalized antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis in a 16-year-old adolescent. The findings highlight the complexity and extended duration of a diagnostic search determined by polymorphic and gradually developing symptoms (damage to the ENT organs, joints, kidneys, and eyes). Therefore, the patient was found to have the specified disease after it had persisted for over a year. Delayed identification of the condition increases the risk of enduring organ damage, which could subsequently result in a poor prognosis despite an initial positive reaction to treatment. Thus, to improve the clinical outcomes of ANCA-associated vasculitis in teenagers, it is essential to raise awareness of the condition’s peculiarities among pediatricians.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>АНЦА-ассоциированный системный васкулит</kwd><kwd>гранулематоз Вегенера</kwd><kwd>гранулематоз с полиангиитом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ANCA-associated systemic vasculitis</kwd><kwd>Wegener's granulomatosis</kwd><kwd>granulomatosis with polyangiitis (GPA)</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">Муркамилов И.
