Трудности диагностики связаны с одной стороны, с необходимостью гистологической верификации диагноза, с другой стороны, с гетерогенностью проявлений заболевания. Частое сосуществование ЭоЭ и других аллергических заболеваний подчеркивает единство патогенетических путей, объединенных реакциями мукозального иммунитета. Приведенный нами клинический случай демонстрирует возможность диагностики ЭоЭ в отсутствии характерных жалоб и эндоскопической картины у пациента, имеющего поливалентную аллергию и длительный анамнез тяжелой БА. Своевременное применение эффективной терапии способствует предотвращению ремоделирования стенки пищевода с развитием стриктур, которые могут значительно ухудшать качество жизни пациента.</p></abstract><trans-abstract xml:lang="en"><p>We presented a clinical case of diagnosing eosinophilic esophagitis in a patient suffering from severe asthma for a long time and receiving therapy with genetically engineered biological drugs: Dupilumab. Difficulties in diagnosis are associated, on the one hand, with the need for histological verification of the diagnosis, and on the other hand, with the heterogeneity of the manifestations of the disease. The frequent coexistence of EoE and other allergic diseases emphasizes the unity of pathogenetic pathways united by mucosal immune reactions. Our clinical case demonstrates the possibility of diagnosing EoE in the absence of characteristic complaints and endoscopic picture in a patient with polyvalent allergies and a long history of severe asthma. Timely use of effective therapy helps prevent remodeling of the esophageal wall with the development of strictures, which can significantly worsen the patient’s quality of life.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Бронхиальная астма</kwd><kwd>гастроэзофагеальная рефлюксная болезнь</kwd><kwd>мукозальный иммунитет</kwd><kwd>Т2-воспаление</kwd><kwd>эозинофильный эзофагит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Bronchial asthma</kwd><kwd>gastroesophageal reflux disease</kwd><kwd>mucosal immunity</kwd><kwd>T2 inflammation</kwd><kwd>eosinophilic</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">Durrani S.R., Mukkada V.A., Guilbert T.W.
