Anti-IL5 therapy is associated with attenuated lung function decline in severe eosinophilic asthma patients from the Belgian Severe Asthma Registry.

BACKGROUND: Asthmatics have accelerated lung function decline over time compared with healthy individuals. OBJECTIVE: To evaluate risk factors for accelerated lung function decline. METHODS: In a longitudinal analysis on severe asthmatics enrolled in the Belgian Severe Asthma Registry with at least 2 visits a minimum of 12 months apart, we compared characteristics of patients with and without decline (loss of post-bronchodilation forced expiratory volume in 1 s [FEV1] (% predicted)/y greater than zero) over time. Multiple linear regression was applied to study the factors independently associa... Mehr ...
