简要总结
The purpose of this cross-sectional, multicenter study is to determine the prevalence of an eosinophilic phenotype of blood eosinophil count ≥ 300 cells/mm3 among severe asthma patients who attend to sites specialized in the management of severe asthma in several countries in the AstraZeneca International Region. The prevalence of an atopic phenotype and asthma control, will also be studied.
详细描述
To determine the prevalence of an eosinophilic phenotype of blood eosinophil count ≥ 300 cells/mm3 among severe asthma patients attending their routine clinical visit at sites specialized in the management of severe asthma in several countries in the AstraZeneca International Region. The prevalence of an atopic phenotype and the status of asthma control, will also be studied. It is expected that this study will contribute to the understanding of severe asthma, ultimately helping to inform therapeutic decisions and addressing patients' needs.
