PG - e00804 LID - 10.1002/rcr2.804 [doi] LID - e00804 AB - Dupilumab, a human monoclonal antibody against interleukin-4 (IL-4) and IL-13, has been approved for treating severe asthma and eosinophilic chronic rhinosinusitis (ECRS). Patients with ECRS are often candidates for endoscopic sinus surgery (ESS). However, a considerable number of patients have recurrent ECRS. ECRS is an important factor influencing asthma control. Here, we present two cases of severe asthma and recurrent ECRS after ESS. Although they had been treated with inhaled corticosteroids and a long-acting beta2-agonist, they experienced frequent asthma exacerbations. Laboratory examinations revealed increased serum eosinophils and immunoglobulin E (IgE). Furthermore, the Asthma Control Test (ACT) score and forced expiratory volume in 1 sec (FEV(1)) were indicative of airway obstruction. After treatment with dupilumab, asthma, rhinosinusitis symptoms, and pulmonary function improved remarkably. Dupilumab therapy improved quality of life in these patients with severe asthma and ECRS.
