概括
直接药物诱导试验 (DPT) 对欧洲成年人非立即反应的青素过敏脱标是安全的. 皮肤测试 (ST) 的值很差,而淋巴细胞转化测试 (LTT) 证实了T细胞参与.
科学领域:
- 过敏和免疫学 过敏和免疫学
- 临床药理学 临床药理学
- 皮肤病学 皮肤病学
背景情况:
- 青素是常见的过敏触发剂,但诊断是复杂的.
- 目前的诊断工作包括皮肤测试 (ST) 和药物诱导测试 (DPT).
- 需要更快的取消标签策略,特别是在欧洲成年人中.
研究的目的:
- 评估欧洲成年人患有低风险青素过敏的直接DPT没有先前的ST的安全性.
- 通过淋巴细胞转化试验 (LTT) 分析ST和T细胞参与的作用.
主要方法:
- 在西班牙马拉加 (2023) 的269名青素过敏患者的前性评估.
- 患者有非立即反应或未知反应.
- 直接单剂量DPT进行;阳性病例接受了ST和LTT.
主要成果:
- 只有5.9%的患者呈阳性DPT,主要是阿莫西西林或阿莫西西林 - 克拉夫兰酸.
- 积极的DPT反应大多是轻微的黄斑斑泡状液.
- 在19%的DPT阳性病例中,ST呈阳性,而LTT在86.7%的病例中呈阳性.
结论:
- 直接单剂量DPT是一种安全的方法,用于在选定的成年患者中取消青素过敏的标签.
- 在这个人群中,ST的诊断价值有限.
- 在青素过敏中,LTT有效地证实了T细胞介导的过敏性.

Allergic Drug Reactions
799
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...

Factors Affecting Drug Response: Overview
1.7K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Pharmacovigilance
755
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.
