Persistence of clinical manifestations and recurrent exacerbations of the disease in adolescents can determine the prognosis for decades of working age, leading to a decrease in the quality of life, socialisation and educational success.</p> <p>Some patients demonstrate severe recurrent course of the disease which do not respond on standard topical anti-inflammatory preparations. Comorbid diseases (not only atopic ones) could serve additional factors complicating atopic dermatitis control achievement. The adolescent patient (well-known for low adherence to topical treatment) could become a special difficulty in clinical management.</p> <p>A clinical case of successful systemic therapy (upadacitinib 15 mg once daily) of severe atopic dermatitis patient comorbid with immunologically-driven joint disease presented. Previous topical treatment of atopic dermatitis was inefficient. Effectiveness (indexes SCORAD and DLQI, digital itch scale) and safety (laboratory data and complains) were evaluated for more than 1 year (15 months) of therapy. Rapid and sustain positive changes in course control of atopic dermatitis with possible T2-associated and other inflammatory mediators were demonstrated.</p></abstract><trans-abstract xml:lang="ru"><p>Атопический дерматит ― гетерогенное в отношении воспалительного патогенеза и прогноза тяжести течения заболевание кожи.</p> <p>Типичными клиническими проявлениями заболевания являются интенсивный зуд и экзематизация кожи.</p> <p>Распространённость атопического дерматита заметно выше у детей, чем у взрослых пациентов. Сохранение клинических проявлений и рецидивы обострений заболевания у подростков могут определять прогноз на десятилетия трудоспособного возраста, приводить к снижению качества жизни, социализации и образовательных успехов.</p> <p>У отдельных пациентов отмечается тяжёлое, непрерывно рецидивирующее течение заболевания, не отвечающее на стандартные наружные противовоспалительные средства. Дополнительным фактором, затрудняющим достижение контроля над течением атопического дерматита, могут стать коморбидные заболевания, в том числе не относящиеся к атопическим. Особенную сложность может представлять ведение такого пациента в подростковом возрасте, для которого характерна низкая приверженность наружной терапии.</p> <p>Представлено описание клинического случая успешной системной терапии (упадацитиниб в дозе 15 мг/сут) пациентки с коморбидным тяжёлым атопическим дерматитом, иммунологически опосредованным поражением суставов и неэффективностью предшествовавшей наружной терапии по основному заболеванию. На протяжении более чем 1 года терапии (15 месяцев) оценивались эффективность (индексы SCORAD и DLQI, числовая шкала зуда) и безопасность (лабораторные и субъективные данные) терапии. Продемонстрирована быстрая и стойкая положительная динамика в достижении контроля над течением атопического дерматита, в патогенезе которого могут участвовать как Т2-ассоциированные, так и другие медиаторы воспаления.</p></trans-abstract><kwd-group xml:lang="en"><kwd>clinical case</kwd><kwd>atopic dermatitis</kwd><kwd>adolescent</kwd><kwd>JAK-inhibitors</kwd><kwd>upadacitinib</kwd><kwd>comorbidity</kwd><kwd>heterogeneity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>клинический случай</kwd><kwd>атопический дерматит</kwd><kwd>подростки</kwd><kwd>ингибиторы янус-киназ</kwd><kwd>упадацитиниб, коморбидность</kwd><kwd>гетерогенность</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Langan SM, Irvine AD, Weidinger S.
