Early and Sustained Response to Benralizumab in Severe, Eosinophilic Asthma: A Real-World Observational Study.

Purpose: Although studies have evaluated benralizumab, a monoclonal IL-5 receptor α antibody in severe eosinophilic asthma (SEA), in real-world settings, additional evidence is needed to further characterize its effectiveness in specific patient populations. Our study aimed to evaluate asthma control over 56 weeks in patients treated with benralizumab in Swiss real-world settings.

Patients And Methods: Conducted across 13 centres, this prospective, observational, non-interventional study involved 73 adults with physician confirmed SEA.

The total-breath method yields higher values of DLCO and TLC than the conventional method.

Background: The 2017 ATS/ERS technical standard for measuring the single-breath diffusing capacity (DLCO) proposed the "rapid-gas-analyzer" (RGA) or, equivalently, "total-breath" (TB) method for the determination of total lung capacity (TLC). In this study, we compared DLCO and TLC values estimated using the TB and conventional method, and how estimated TLC using these two methods compared to that determined by body plethysmography.

Method: A total of 95 people with COPD (GOLD grades 1-4) and 23 healthy subjects were studied using the EasyOne Pro (ndd Medical Technologies, Switzerland) and Master Screen Body (Vyaire Medical, Höchberg, Germany).

Functional Predictors Discriminating Asthma-COPD Overlap (ACO) from Chronic Obstructive Pulmonary Disease (COPD).

Background: A significant proportion of patients with obstructive lung disease have clinical and functional features of both asthma and chronic obstructive pulmonary disease (COPD), referred to as the asthma-COPD overlap (ACO). The distinction of these phenotypes, however, is not yet well-established due to the lack of defining clinical and/or functional criteria. The aim of our investigations was to assess the discriminating power of various lung function parameters on the assessment of ACO.
