概括
在自身免疫艾迪逊病 (AAD) 患者的剩余上腺皮功能 (RAF) 影响了血甲基氨酸 (MN) 水平. 即使是最小的内源性皮质醇产生也会影响MN,突出显示上腺功能和甲基醇胺代谢物之间的联系.
科学领域:
- 内分泌学 在内分泌学.
- 代谢研究的研究.
- 临床诊断 临床诊断 临床诊断
背景情况:
- 剩余的上腺皮功能 (RAF) 在约三分之一的患有自身免疫阿迪森病 (AAD) 的患者中存在.
- 在AAD中RAF的临床意义,特别是它对神经内分泌标记物的作用,仍然不完全理解.
研究的目的:
- 调查RAF对AAD患者血甲基内 (MN) 和诺米甲基内 (NMN) 水平的影响.
- 为了检查在RAF和没有RAF的患者中,在辅热激素刺激后,MN和NMN的变化.
主要方法:
- 一组70名AAD患者 (50名RAF患者,20名对照患者) 接受了可辛素刺激测试.
- 在基线,30分钟和60分钟后收集血液样本以分析血清皮质醇和血MN/NMN,使用LC-MS/MS.
- 在采样之前,患者暂时停止了葡萄糖皮质类药物和弗鲁多皮质替代剂的治疗.
主要成果:
- 在基线33%的患者中可以检测到甲基尼 (MN),在刺激后略有下降.
- 与对照组相比,RAF患者在基线和60分钟显示出可检测的MN的可能性更高 (分别为p=0.035和p=0.048).
- 在所有时间点检测到的MN和皮质醇水平之间观察到正相关性 (p<0.001). 诺美坦尼弗林 (NMN) 水平保持不变.
结论:
- 即使是最小的内源性皮质醇产生,表明RAF,在AAD患者中显著影响血MN水平.
- 这些发现表明,在AAD中,监测MN作为与剩余上腺功能相关的标志物具有潜在的作用.

1.7K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

01:31Hormones of the Adrenal Glands
2.6K
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

01:17Anatomy of the Adrenal Glands
2.4K
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
The adrenal gland comprises two distinct...

01:30Adrenergic Agonists: Therapeutic Uses
858
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.

01:27Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
1.4K
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
