摘要:

The article reports on research which attempted to determine if eosinophilic inflammation of the airway is associated with the risk of exacerbations of asthma. Researchers conducted a randomized, double-blind, placebo-controlled, parallel-group study of 61 subjects who had refractory eosinophilic asthma and a history of recurrent severe exacerbations. They found that mepolizumab was associated with significantly fewer severe exacerbations than placebo over the course of 50 weeks and that mepolizumab significantly lowered eosinophil counts in the blood (P<0.001) and sputum (P=0.002). They concluded that mepolizumab therapy reduces exacerbations and improves AQLQ scores in patients with refractory eosinophilic asthma.and that eosinophils have a role as important effector cells in the pathogenesis of severe exacerbations of asthma in the patient population that they studied.
