概括
室内灰尘子皮下免疫疗法 (HDM SCIT) 在过敏性鼻炎患者中显示出症状改善的趋势,但与安慰剂没有显著差异. 需要进一步的研究来确认长期益处和疾病修饰.
科学领域:
- 过敏和免疫学 过敏和免疫学
- 免疫治疗是一种免疫疗法.
- 临床试验 临床试验
背景情况:
- 之前的家用灰尘子皮下免疫疗法 (HDM SCIT) 试验在样本大小和基线治疗标准化方面存在局限性.
- 在HDM SCIT的最佳基线治疗方面缺乏共识.
研究的目的:
- 评估HDM SCIT在中度至重度过敏性鼻炎 (AR) 患者的疗效,这些患者接受了基线的鼻内皮质类固醇 (INCS).
主要方法:
- 进行了一项随机的,安慰剂对照试验,涉及皮肤病原虫pteronyssinus (Derp) 敏感患者.
- 所有参与者都按照ARIA指南接受了标准护理,包括INCS.
- 主要终点是12个月后鼻腔症状和药物使用的复合得分.
主要成果:
- 该研究包括144名患者 (108名HDM-SCIT,36名安慰剂).
- 一年后,在HDM-SCIT和安慰剂组之间没有观察到复合得分的显著差异 (p > 0.05).
- 在HDM-SCIT组中,血清Derp特定IgG4水平显著增加 (p ≤0.001).
结论:
- 一年长的HDM SCIT显示出过敏性鼻炎症状和药物减少的趋势,但在与INCS同时使用时,并没有明显优于安慰剂.
- 建议进行长期研究,以探索疾病修饰潜力.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
241
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...

01:25Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
224
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
