概括
在接受 cetuximab 治疗之前,评估 alpha-gal 特定 IgE 是至关重要的. 使用alpha-gal和cetuximab的基细胞激活测试 (BAT) 能够有效预测严重的过敏反应,有助于对过敏反应风险的评估.
科学领域:
- 免疫学 免疫学 免疫学
- 药理学 药理学是指药理学的学科.
- 过敏和临床免疫学
背景情况:
- 塞图西马布的使用可能会在初次暴露时引发过敏反应.
- 预测严重反应对于 cetuximab 治疗期间的患者安全至关重要.
- 阿尔法-加尔综合征是一个与红肉过敏和潜在的 cetuximab 反应有关的新兴问题.
研究的目的:
- 评估基激活试验 (BAT) 对α-gal和cetuximab的诊断实用性.
- 预测对 cetuximab 的过敏反应的严重程度.
- 为了评估 cetuximab 诱导的过敏反应的风险.
主要方法:
- 对38名接受 cetuximab 初始治疗的患者进行前性研究.
- 在 cetuximab 服用前测量血清IgE (sIgE) 到alpha-gal的水平.
- 皮肤试验和BAT与alpha-gal和cetuximab在alpha-gal敏感患者的表现.
主要成果:
- 24%的患者表现出对α-gal的sIgE升高;8/9对 cetuximab作出反应.
- 对alpha-gal的BAT在所有敏感患者中都是积极的,在严重反应中激活率更高 (p=0.03).
- 对 cetuximab 的 CD63 BAT 阳性反应与严重的 4 级反应 (p≤0.001) 有很强的相关性.
结论:
- 在启动 cetuximab 治疗之前,应评估血清IgE 到alpha-gal.
- 使用alpha-gal或cetuximab的BAT可以预测反应严重程度和过敏反应风险.
- 这些测试有助于对有严重过敏症的危险患者进行分层对 cetuximab.

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
267
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...
