概括
较高的血中乙氨基酸基数 (BEC) 和分数呼出的氧化 (FeNO) 预测了生物治疗严重喘患者的肺功能改善. 这些生物标志物,特别是结合起来,可以指导个性化治疗策略.
科学领域:
- 肺病学和呼吸系统医学
- 免疫学 免疫学 免疫学
- 生物标志物发现发现
背景情况:
- 之前关于严重喘前生物标志物和后生物结果的研究仅限于单个生物标志物和受控试验.
- 关于联合生物标志物对喘生物治疗反应的预测价值的现实数据很少.
研究的目的:
- 在现实环境中研究生物治疗后,预生物标志物水平 (个体和组合) 与喘结果的变化之间的关系.
- 评估免疫球蛋白E (IgE),血液中乙氨基酸计数 (BEC) 和部分呼出的氧化 (FeNO) 对治疗反应的预测值.
主要方法:
- 来自国际严重喘登记处的3751名严重喘患者的基于登记处的队列研究 (2017年5月-2023年2月).
- 研究了IgE,BEC和FeNO的生物学前水平.
- 对恶化率,症状控制和肺功能 (FEV1) 的12个月前至12个月后生物学变化进行了分析.
主要成果:
- 在抗IgE,抗IL5/5R和抗IL4Rα疗法中,更高的生前BEC和FeNO与更大的生后FEV1改善有关.
- 生物学前BEC预测抗IL5/5R的生物学后非控制性喘的可能性较低.

Bronchodilators are critical in managing asthma, a chronic respiratory condition characterized by airway constriction due to inflammation and hyper-reactivity. Specifically, bronchodilators ease this constriction by relaxing the bronchial muscles, facilitating easier breathing.
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce...

125
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
277
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
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...
