概括
一名儿科患者因银河糖-α-1,3-银河糖 (alpha-gal) 过敏而经历过敏反应,包括疹,在因银河糖-α-1,3-银河糖 (alpha-gal) 过敏后输注. 症状在转换为阿达利穆马布后消失,突出显示阿尔法作为生物疗法中的潜在过敏原.
科学领域:
- 免疫学 免疫学 免疫学
- 胃肠病学 胃肠病学
- 过敏学 过敏学
背景情况:
- 哺乳动物肉类过敏包括对银河糖-α-1,3-银河糖 (alpha-gal) 的延迟过敏.
- 阿尔法-在非灵长类哺乳动物和生物制剂中存在,如infliximab.
- 这种过敏可以表现为对来自哺乳动物来源的药物的反应.
研究的目的:
- 描述一个克罗恩病的儿科病例,呈现出对infliximab的过敏反应.
- 调查婴儿病人的Infliximab治疗和哺乳动物肉类过敏的发展之间的联系.
- 评估在疑似因弗力西马布诱导的α-gal过敏的患者中阿达利穆马布的疗效.
主要方法:
- 一个患有克罗恩病的儿科患者的病例报告.
- 监测患者的过敏反应 (尿疹,) 在infliximab输注后.
- 通过血清IgE对alpha-gal的升高来诊断哺乳动物肉类过敏.
- 停止使用infliximab并开始使用adalimumab治疗.
主要成果:
- 患者在第一次注射Infliximab后大约6小时内出现了疹和.
- 症状进展为慢性疹,随后接受了因弗利西马布治疗.
- 诊断证实了高血清IgE特定于alpha-gal.
- 在停止使用infliximab并开始使用adalimumab后,症状完全消失.
结论:
- 在易受影响的个体中,infliximab可以触发银河糖-α-1,3-银河糖 (alpha-gal) 过敏,甚至在儿童群体中.
- 对于患有对含有α-gal的生物制品过敏反应的患者,应考虑哺乳动物肉类过敏.
- 在这种情况下,Adalimumab可以作为一种安全有效的替代治疗方法.

Hypersensitivities
737
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...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
173
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Allergic Drug Reactions
875
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...
