概括
与输液相关的反应 (IRR) 在阿尔茨海默病 (AD) 的多纳尼马布治疗中很常见,大多为轻度至中度. 以前的药物过敏预测了IRR,但重新挑战往往是可以容忍的.
科学领域:
- 神经学 神经学
- 药理学 药理学是指药理学的学科.
- 免疫学 免疫学 免疫学
背景情况:
- 输液相关反应 (IRR) 和过敏是已知的与治疗抗体相关的不良事件.
- 描述IRR对于有效预测和管理这些事件至关重要.
- 这项研究重点关注早期症状性阿尔茨海默病 (AD) 的多纳尼马布治疗.
研究的目的:
- 在接受donanemab治疗早期症状性阿尔茨海默病 (AD) 的参与者中描述输液相关反应 (IRR).
- 确定IRR的预测因素,并评估IRR后重新挑战的结果.
- 评估IRR与实验室标记物 (如三酶水平) 之间的关联.
主要方法:
- 从多个donanemab临床试验 (TRAILBLAZER-ALZ,TRAILBLAZER-ALZ 2等) 的数据进行了汇总. ) 的情况.
- 用于描述IRR和相关事件的描述性统计数据.
- 一个随机森林模型确定了IRR和40个基线变量之间的潜在关联.
主要成果:
- 在2727名接受donanemab治疗的参与者中,有8.3%的参与者经历了IRR,大多为轻度至中度.
- 常见的症状包括恶心/吐,寒和红斑.
- 以前的药物过敏和过敏反应是IRR的显著预测因素 (p < 0.01).
- 在37.9%的参与者中,随着可用的IRR后和基线实验室值的增加,观察到酸酶水平升高.
- 重复注射通常是可以容忍的,65.1%之前经历过IRR的参与者接受了随后的注射.
- 用抗组胺剂进行预防并没有降低重新挑战时的IRR风险.
结论:
- 输液相关反应 (IRR) 是阿尔茨海默病 (AD) 的多纳尼马布治疗期间常见的现象.
- 大多数IRR是轻度到中度的,重试通常是成功的.
- 严重的IRR和过敏反应可能会发生,强调需要仔细监测.
- 预测因素,如先前的药物过敏和过敏反应,需要考虑风险管理策略.

Alzheimer's Disease: Treatment
1.1K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Alzheimer's Disease: Overview
1.9K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...
