Abstract
Background: Studies comparing biological therapies for severe asthma usually have a selection bias considering that some of these therapies are indicated for allergic asthma and others for eosinophilic asthma. Severe mixed asthma (SMA) was considered in patients with both allergic and eosinophilic (mixed) severe asthma. In SMA, dupilumab, omalizumab, mepolizumab, and benralizumab, can be used. Currently there are no head-to-head studies comparing the clinical response of biological therapies in this group of patients.
Objective: To compare the effectiveness of four biological therapies in SMA.
Methods: Prospective study with one year of follow-up. Severe asthma patients with markers for allergic asthma (total IgE >100IU/L and sIgE to aeroallergens) and eosinophilic asthma (Eosinophils >150 cells/ml) were recruited. Sociodemographic and clinical characteristics were evaluated at baseline to assess significant differences between groups. The primary outcome was the proportion of patients achieving > 20 points in the Asthma Control Test (ACT), and as secondary outcomes we evaluated the number of severe exacerbations of asthma per year and change in FEV1.
Results: A total of 133 patients participated in the study (dupilumab n=43, omalizumab=32, mepolizumab=32, benralizumab=26). At baseline, the groups did not have significant differences in sociodemographic or clinical characteristics. After one year with biological therapies, the four groups presented a significant improvement in clinical outcomes with few between groups differences. There was no difference for the main outcome (ACT) in the four groups. Dupilumab and mepolizumab demonstrated a higher interval improvement in FEV1 than omalizumab. Dupilumab users had the highest proportion of patients who achieved a 200 ml improvement in FEV1 over omalizumab and benralizumab. The greatest adherence was observed among benralizumab users.
Conclusion: In SMA the four biological therapies offer similar symptom control according to ACT but there are some differences according to FEV1 and adherence. Therefore, the selection of these therapies in SMA must be based on particular aspects of each patient.
期刊介绍:
JACI: In Practice is an official publication of the American Academy of Allergy, Asthma & Immunology (AAAAI). It is a companion title to The Journal of Allergy and Clinical Immunology, and it aims to provide timely clinical papers, case reports, and management recommendations to clinical allergists and other physicians dealing with allergic and immunologic diseases in their practice. The mission of JACI: In Practice is to offer valid and impactful information that supports evidence-based clinical decisions in the diagnosis and management of asthma, allergies, immunologic conditions, and related diseases.
This journal publishes articles on various conditions treated by allergist-immunologists, including food allergy, respiratory disorders (such as asthma, rhinitis, nasal polyps, sinusitis, cough, ABPA, and hypersensitivity pneumonitis), drug allergy, insect sting allergy, anaphylaxis, dermatologic disorders (such as atopic dermatitis, contact dermatitis, urticaria, angioedema, and HAE), immunodeficiency, autoinflammatory syndromes, eosinophilic disorders, and mast cell disorders.
The focus of the journal is on providing cutting-edge clinical information that practitioners can use in their everyday practice or to acquire new knowledge and skills for the benefit of their patients. However, mechanistic or translational studies without immediate or near future clinical relevance, as well as animal studies, are not within the scope of the journal.
