概括

甲氨酸可以作为皮质醇的替代品,用于上腺静脉采样 (AVS) 在初级阿尔多斯特隆症 (PA),特别是当皮质醇结果不清楚时. 然而,由于成本和可用性,皮质醇仍然是标准的,而甲氨酸作为补充选择.

科学领域:

内分泌学在内分泌学.
临床化学临床化学
手术创新在外科创新.

背景情况:

主要阿尔多斯特主义 (PA) 的诊断和治疗取决于通过上腺静脉采样 (AVS) 准确的亚型.
对AVS选择性的皮质醇测量可以受到昼夜变化,压力或共同分泌的限制,影响诊断准确度.
研究替代生物标志物,如甲氨酸,对于改善AVS解释性至关重要.

研究的目的:

为了评估甲尼林作为皮质醇的替代品在评估选择性和侧面化在AVS的PA期间.
为了比较基於甲氨酸与皮质醇的AVS解释的诊断一致性和临床实用性.
为了确定甲尼林在皮质醇测定解释性有限的情况下是否提供优势.

主要方法:

对102名经过AVS治疗的PA患者进行了回顾性分析.
选择性和横向化速率的比较,使用皮质醇和甲基氨酸测定,并定义了截止点.
包括重复采样和不同程度的皮质醇共分泌的患者.

主要成果:

基于皮质醇的AVS实现了90.2%的双边选择性.
甲氨酸和皮质醇显示了83.6%的一致选择性分类,非选择性样本的比例相似.
侧面化指数显示,甲非林和皮质醇之间81%的一致性,基于皮质醇共分泌的选择性或侧面化没有显著差异.

结论:

甲非林是一种可行的替代生物标志物,用于对初级阿尔多斯泰龙症的AVS解释,特别是当皮质醇测量是模两可的时.
在经验丰富的中心与优化的协议,甲基氨酸并没有超过皮质醇对AVS.
由于成本和可访问性,皮质醇仍然是AVS的主要标准,而甲基内弗林在特定的临床场景中是有价值的辅助剂.

Adrenergic Agonists: Therapeutic Uses

Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Adrenergic Agonists: Mixed-Action Agents

Adrenergic Agonists: Mixed-Action Agents

Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
