概括
多发性硬化症 (MS) 患者对ocrelizumab的IgE介导过敏反应罕见但显著. 过敏史和较少的输液是危险因素,ofatumumab是安全的替代品.
科学领域:
- 免疫学 免疫学 免疫学
- 神经学 神经学
- 药理学 药理学是指药理学的学科.
背景情况:
- 针对CD20的单克隆抗体ocrelizumab是多发性硬化症 (MS) 的关键治疗方法.
- 输液相关反应 (IRR) 是常见的与ocrelizumab,但IgE介导的过敏反应是罕见的,并没有很好地理解.
- 了解这些罕见的过敏反应对于患者的安全和治疗管理至关重要.
研究的目的:
- 确定MS患者对ocrelizumab IgE介导过敏反应的发生率.
- 为了确定与这些罕见的过敏反应相关的危险因素.
- 评估诊断方法和替代治疗选择.
主要方法:
- 在2018年至2024年期间,对387名多发性硬化症患者接受了ocrelizumab治疗的回顾性分析.
- 过敏性评估,包括皮肤刺伤测试 (SPT) 和皮内测试 (IDT),用于严重的IRR (等级≥3).
- 统计分析以确定IgE介导反应的独立预测因子.
主要成果:
- 在387名患者中,有24.3%的患者经历了IRR,其中4.9%是3级.
- 六名患者 (1.6%) 被诊断出IgE介导反应,通过积极的IDT和临床症状得到证实;SPT是负的.
- 在IgE阳性患者中,过敏史 (66.7%与26.5%,p=0.028) 显著更常见. 过敏史 (OR 11.5) 和较少的输液 (OR 0.60) 是独立的危险因素.
- 在6名患者中,有5名患者能够耐受转换为ofatumumab.
结论:
- 对ocrelizumab的IgE介导过敏反应虽然不常见,但需要及时识别.
- 皮内检测 (IDT) 是这些反应的宝贵诊断工具.
- 患有过敏史的患者可能面临更高的风险. 奥法图马布为已确认对奥克雷利祖马布过敏的患者提供了安全的替代方案.

Allergic Drug Reactions
1.3K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
1.7K
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...

Pharmacovigilance
1.6K
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

Hypersensitivities
7.2K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...
