Clinical Case of Diagnosis of Eosinophilic Esophagitis in A Patient Who Was Suffering for A Long Time with Severe Bronchial Asthma and Receiving Therapy with A Gerd (Dupilumab)

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.
