Nasal polyposis (NP) is a comorbidity of type 2 severe asthma (SA) which could influence response to SA biologics.
We evaluated (super-) response in SA patients with (NP +) and without NP (NP-) enrolled in the Belgian Severe Asthma Registry (BSAR).
914 patients, of whom 31% NP + , were included. At enrollment, NP + patients had higher annual exacerbation rates, higher number of emergency room visits and more elevated type 2 biomarkers. In the longitudinal subanalysis of 104 patients, both groups had significant and similar asthma responses to asthma biologics, except for a greater increase in FEV in the NP + group. Super-response was achieved in 33 patients (32%), irrespective of NP status or type of biologic.
In conclusion, both NP + and NP - patients had positive treatment responses, with some able to achieve super-response. In SA patients with NP, a greater FEV improvement as compared to SA patients without NP was observed.
鼻息肉病（NP）是2型重度哮喘（SA）的一种合并症，可能影响对SA生物制剂的反应。
我们评估了比利时重度哮喘登记处（BSAR）登记的伴有NP（NP+）和不伴有NP（NP-）的SA患者的（超）反应。
纳入了914例患者，其中31%为NP+。入组时，NP+患者的年加重率更高、急诊就诊次数更多且2型生物标志物水平更高。在对104例患者的纵向亚分析中，两组对哮喘生物制剂的哮喘反应均显著且相似，但NP+组的第一秒用力呼气容积（FEV）增加幅度更大。33例患者（32%）实现了超反应，与NP状态或生物制剂类型无关。
总之，NP+和NP-患者均有积极的治疗反应，部分患者能够实现超反应。在伴有NP的SA患者中，与不伴有NP的SA患者相比，观察到FEV改善更明显。
