概括
在急性缺血性中风患者中,补充甲基普雷尼索隆并没有改善残疾的结果. 然而,它显著降低了这一组患者的死亡率和症状性内出血率.
科学领域:
- 神经学
- 临床试验
- 药理学
背景情况:
- 由于大血管封闭而导致的急性缺血性中风 (LVO) 是需要快速干预的危急情况.
- 血管内血栓切除术是LVO的标准治疗方法,但结果可能会变化.
- 静脉注射甲基普雷迪尼索隆等辅助疗法的作用在改善结果方面仍然不确定.
研究的目的:
- 在LVO引起的急性缺血性中风患者中,评估低剂量静脉注射甲基普雷尼索隆作为内静脉血栓切除术的辅助剂的疗效和安全性.
- 评估甲基普雷尼索隆对残疾,死亡率和症状性内出血的影响.
主要方法:
- 这是一项随机,双盲,安慰剂对照试验,涉及中国82家医院的1680名患者.
- 患有急性缺血性中风和临近内LVO的患者随机分别接受静脉注射甲基普雷尼索隆 (2 mg/ kg/ 天3天) 或安慰剂,此外还进行了血管内血栓切除术.
- 主要疗效结论是90天后修改的兰金评分;安全结论包括90天死亡率和48小时内症状性内出血.
主要成果:
- 补充甲基普雷尼索隆在90天后没有显著改善修改后的兰金评分的整体分布 (调整后的几率比,1. 10;P=. 17).
- 甲基普雷尼索隆组在90天内死亡率显著降低 (23. 2% 与 28. 5% 相比; P=. 03).
- 在甲基普雷迪尼索隆组中观察到明显较低的症状性内出血率 (8. 6% 与 11. 7% 相比; P=. 04).
结论:
- 在LVO引起的急性缺血性中风患者的内血管血栓切除术后,静脉注射甲基普雷尼索隆并没有显著改善整体残疾.
- 甲基普雷尼索隆通过降低死亡率和症状性脑内出血的发生率显示出潜在的益处.
- 在此背景下,进一步的研究可能会探索最佳的患者选择或治疗方案.

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists
295
Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists

Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Clinical Trials: Overview
4.3K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
