Allergy and asthma proceedings
|October 29, 2025
概括
这项研究引入了一种新的诊断方法,用于儿童对丹塞过敏的诊断. 皮肤刺伤测试 (SPT) 显示敏感性低,而皮内测试 (IDT) 和药物诱导测试 (DPT) 证明在诊断丹塞过敏时具有价值.
科学领域:
- 儿科过敏和免疫学
- 临床药理学 临床药理学
- 药物过敏的诊断 药物过敏的诊断
背景情况:
- 丹塞是一种广泛使用的抗药,很少引起过敏反应.
- 诊断工具,如皮肤刺探测试 (SPT) 和皮肤内测试 (IDT) 对于丹塞过敏的敏感性不清楚,特异性和最佳度.
- 药物挑测试 (DPT),黄金标准,以前没有记录在儿科ondansetron过敏病例.
研究的目的:
- 在儿科患者中评估对疑似丹塞过敏的初步诊断策略.
- 评估SPT,IDT和DPT在诊断儿童丹塞过敏症中的有用性.
主要方法:
- 对儿童患者 (3-16岁) 的回顾性审查,评估了对丹塞过敏性的评估 (2019-2025年).
- 连续的诊断测试:SPT (2 mg/mL的翁丹塞特朗),其次是IDT (0.02和0.2 mg/mL) 对于负的SPT结果.
- 对那些皮肤测试结果为负的患者进行了药物诱导测试 (DPT).
主要成果:
- 所有七名儿科患者的SPT结果均为负,表明敏感性低.
- 在有过敏反应史的三名患者中,IDT呈阳性 (其中一人0.02 mg/mL,两人0.2 mg/mL).
- 在皮肤检测结果为负的4名患者中,有3名患者的DPT呈阴性;整体而言,有3名患者的过敏性得到证实.
结论:
- 这是第一个建议使用DPT诊断方法的儿科病例系列,用于治疗ondansetron过敏症.
- SPT表现出有限的敏感性,而IDT是有价值的,特别是在过敏症的情况下.
- DPT似乎是安全的,并且适用于患有阴性皮肤测试结果的儿科患者,以检测ondenansetron过敏症.

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
594
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption
240
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

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...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists
801
Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.

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...
