RESUMO

INTRODUCTION: Asthma is one of the most common chronic diseases and affects around 334 million people worldwide. The estimated prevalence of severe asthma is 3-10% of the asthmatic population. Mepolizumab has demonstrated efficacy in reducing exacerbations, oral corticosteroid use, and improving quality of life, asthma control, and lung function in patients with severe eosinophilic asthma (SEA). Our study aimed to check the response to mepolizumab in a series of severe asthma patients regarding exacerbations, oral corticosteroid use, asthma control, quality of life, and lung function and to compare the response between patients with and without nasal polyps. METHOD: This is a retrospective, multicenter study of RE-ASGRAMUR (Register of Severe Asthma of the Region of Murcia) performed in eight hospitals of the Region of Murcia (Spain) under routine clinical practice conditions. We included patients diagnosed with SEA who completed at least 1 year of treatment with mepolizumab. We analyzed clinical characteristics, drug tolerance, and effectiveness: exacerbations, ACT, miniAQLQ, forced expiratory volume in 1 s (FEV1), and use of oral corticosteroids. We also compared the results between patients with and without nasal polyps. RESULTS: The median of exacerbations before treatment was 3 and decreased to 0 after treatment (mean decrease of 77.4%). The median diary oral prednisone intake was 15 mg before treatment and 5 mg after treatment (mean 56% reduction). We have obtained a significant improvement in other variables: ED visits and hospitalizations, asthma control (ACT), quality of life (miniAQLQ), and lung function (FEV1). Thirty-four out of 70 patients (48.57%) fulfilled the criteria of super-responder, and 17 out of 70 (24.29%) had a complete response. More patients in the group with nasal polyps fulfilled the criteria of super-responder and complete response to mepolizumab. CONCLUSIONS: Mepolizumab is a safe and effective treatment for SEA patients, improving exacerbations, oral corticosteroid intake, asthma control, quality of life, and lung function. In patients with associated nasal polyposis, there is a statistically significant higher proportion of super-responders and complete responders.

RESUMO

INTRODUCTION: Clinical trials and real-life studies have been published showing effectiveness of benralizumab in severe eosinophilic asthmatic patients. The aim of the present study is to describe super-responders to benralizumab in a series of 79 patients who completed at least 1 year of treatment, and to compare super-responders with non super-responders. METHODS: This is a multicenter study of the Register of Severe Asthma of the Region of Murcia (RE-ASGRAMUR) Group performed in eight hospitals under the conditions of routine clinical practice. Patients with zero exacerbations and no oral corticosteroid therapy for asthma were considered super-responders. We analyzed clinical, functional, and inflammatory parameters of selected patients. RESULTS: In all, 50 of the 79 patients (63%) met the super-responder criteria. In addition, 36% of the patients (26/71) were considered as complete responders to treatment (super--responder + Asthma Control Test [ACT] ≥ 20 + forced expiratory volume in 1 s [FEV1] ≥ 80%). The super--responders were significantly older in age (P = 0.0029), had higher eosinophils count (P = 0.0423), higher proportion of nasal polyps (P = 0.036), and they had less severe disease at baseline. After 1 year of treatment, the super-responders had higher levels of ACT questionnaire (23 vs 19, P = 0.0007) and better percentage of FEV1 (83 vs 75, P = 0.0359). CONCLUSION: Almost two of the three patients treated with benralizumab were super--responders after 1 year of treatment and 36% had a complete response. Super-responders were associated with older age, higher eosinophils count, had nasal polyposis as comorbidity, and had less severe disease at baseline. This data illustrated the good real-life response of patients with severe eosinophilic asthma to the treatment with benralizumab.
