Patients With Severe Eosinophilic Asthma Treated With Benralizumab

Retrospective study studying severe eosinophilic asthma. Patients with this disease who are on benralizumab treatment for at least 4 months before the start of the study will be included. The purpose of this study is to analyze the predictive factors of response in patients with this type of disease treated with benralizumab, who obtain a complete response during their follow-up. The results of the study will be obtained through the review of medical records, where demographic characteristics such as age, gender and smoking will be assessed; presence of comorbidities; clinical-functional variables; response variables (exercises, cycles of oral corticosteroids, admissions, visits to the emergency room or unscheduled, cumulative dose of oral corticosteroids, absenteeism from work) and side effects.
