Background: The ORBE II study showed the real-world effectiveness of benralizumab in severe eosinophilic asthma (SEA). This subgroup analysis aimed to characterize patients and outcomes based on baseline blood eosinophil count (BEC) and/or fractional exhaled nitric oxide (FeNO) levels.
Methods: In this analysis of the ORBE II retrospective study, SEA patients receiving benralizumab were categorized into subgroups based on individual or combined BEC/FeNO levels, according to the following thresholds: high BEC (hiBEC): ≥300 cells/μL; low BEC (loBEC): <300 cells/μL; high FeNO (hiFeNO): ≥50 ppb; low FeNO (loFeNO): <50 ppb.

Asthma is a chronic inflammatory disease that affects about 5% of the world's population and generates high health and social costs. Proper management of the disease requires a correct diagnosis, based on objective measures of functional impairment, as well as symptom control and assessment of the future risk of exacerbations.It has been estimated that 18% of asthma patients in Western Europe have severe asthma and approximately 50% of them have poor control.

Tezepelumab, a human monoclonal antibody (mAb), inhibits thymic stromal lymphopoietin, a pivotal factor in the pathophysiology of asthma. Although randomized clinical trials have demonstrated the efficacy of Tezepelumab, evidence gaps remain in real-world scenarios.

USA is a heterogeneous entity with different endotypes and phenotypes. Nowadays, the biological drugs approved with asthma indication are omalizumab, mepolizumab, reslizumab, benralizumab and dupilumab.

The aim of this study was to compare the effectiveness of biologics in these two conditions. We included 318 patients (24 ACO and 297 asthma) treated with monoclonal antibodies and followed for at least 12 months.

This paper, developed by consensus of staff physicians of accredited asthma units for the management of severe asthma, presents information on the process and requirements for already-existing asthma units to achieve official accreditation by the Spanish Society of Pneumology and Thoracic Surgery (SEPAR). Three levels of specialized asthma care have been established based on available resources, which include specialized units for highly complex asthma, specialized asthma units, and basic asthma units. Regardless of the level of accreditation obtained, the distinction of "excellence" could be granted when more requirements in the areas of provision of care, technical and human resources, training in asthma, and teaching and research activities were met at each level.
