概括
治疗性血交换 (PEX) 可以改善严重的阿马托克辛相关急性肝衰竭 (AT-ALF) 患者的无肝移植生存率. 这项回顾性研究发现,PEX对肝脏脑病发作2级或更高的患者有益.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 毒理学 毒理学 毒理学
- 关键护理医学 关键护理医学
背景情况:
- 与氨毒素相关的急性肝衰竭 (AT-ALF) 在没有肝移植的情况下死亡率很高.
- 在AT-ALF中治疗性血交换 (PEX) 的疗效仍然不确定.
- 对像AT-ALF这样的罕见疾病进行随机对照试验具有挑战性.
研究的目的:
- 调查治疗性血交换 (PEX) 对AT-ALF.患者的无肝移植生存率的影响.
- 评估PEX作为AT-ALF辅助疗法的安全性和有效性.
- 提供现实世界的证据,以指导临床实践管理AT-ALF.
主要方法:
- 一项多中心的国际回顾性研究 (Amanita-PEX) 从2013年到2024年分析了111名患有AT-ALF的患者.
- 患者接受了标准护理 (SOC) 或至少一次PEX会话.
- 主要结局是28天的无肝移植生存期.
主要成果:
- 虽然整体28天存活率没有显著差异,但PEX在肝脏脑病变 (HE) 级别≥2.2的患者中显示有好处.
- 在HE≥2小组中,PEX与较高的无LTX存活率有关 (36.4%与SOC中的19.1%相比).
- 在HE≥2 (HR0.37) 的患者中,PEX在28天内独立降低了死亡或LTX的风险.
结论:
- 辅助治疗性血交换 (PEX) 与AT-ALF和肝脑病变等级≥2.2的患者的无肝移植生存率增加有关.
- 这些发现表明PEX可能是严重AT-ALF病例的有价值的治疗选择.
- 进一步的研究可以探索AT-ALF管理的最佳PEX协议.

Anticholinesterase Agents: Poisoning and Treatment
1.5K
Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...
