基线分数呼出的氧化 (FeNO) 水平可以预测严重喘的治疗反应. 较高的FeNO水平 (≥25ppb) 与改善的肺功能和减少与抗IL-5/5R生物药物的口服皮质类固醇使用有关.
科学领域:
- 呼吸系统医学 呼吸系统医学
- 免疫学 免疫学 免疫学
- 生物标志物 生物标志物
背景情况:
- 严重喘管理仍然具有挑战性,生物治疗反应的预测因素有限.
- 抗干白素-5 (IL-5) 和抗干白素-5受体 (IL-5R) 生物药物对酸性喘有效.
- 在预测治疗结果方面,基线部分呼出的氧化 (FeNO) 的作用尚未完全确定.
研究的目的:
- 调查基线FeNO水平是否可以预测在严重喘中对抗IL-5/5R生物药物的治疗反应.
- 评估FeNO水平对肺功能,临床症状和类固醇节约效应的影响.
主要方法:
- 分析了一组104名患有严重酸性喘的患者,这些患者接受了抗IL-5/5R生物药物治疗.
- 患者根据基线FeNO水平 (<25ppb与≥25ppb) 进行了分层.
- 评估了FEV1,FEF25-75,喘控制测试 (ACT) 分数,恶化和皮质类固醇剂量的变化.
主要成果:
- 在治疗后,FeNO基线较高 (≥25ppb) 的患者在FEV1% (11.2%对3.34%,p=0.012) 和FEV25-75% (9.6%对2.1%,p=0.05) 中显著改善.
- 较高比例的FeNO≥25ppb患者减少或停止服用口服皮质类固醇 (94.1%与71.7%相比).
- 多变量分析证实FeNO≥25ppb作为改善肺功能和减少口服皮质类固醇使用的预测因素.
结论:
- 基线FeNO水平可以作为在严重的eosinophilic喘中对抗IL-5/5R生物治疗反应的预测生物标志物.
- 较高的FeNO水平与更好的肺功能改善和更大的类固醇节约效应有关.
- FeNO有可能指导治疗选择,以优化严重喘的结果.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
