概括
68Ga-Pentixafor PET/CT准确地预测了原发性阿尔多斯顿症 (PA) 患者的手术结果,与上腺静脉采样 (AVS) 相似. 在PET/CT上较高的SUVmax值可以指导在PA管理中进行更少侵入性的腹腔镜部分上腺切除术的决定.
科学领域:
- 内分泌学和核医学 核医学
- 瘤成像和诊断 瘤成像和诊断
- 手术预测结果的预测.
背景情况:
- 原发性阿尔多斯子症 (PA) 的诊断和管理需要精确的阿尔多斯子产生腺瘤的横向化.
- 目前的诊断方法,如上腺静脉采样 (AVS),具有侵入性和局限性.
- 需要新的成像技术来改善PA患者手术成功的预测.
研究的目的:
- 为了比较68Ga-Pentixafor PET/CT与AVS在预测PA上腺切除术后的功能结果中的准确性.
- 评估68Ga-Pentixa对于PET/CT在指导腹腔镜部分上腺切除术中的有用性.
- 确定PA中成功手术结果的成像预测因素.
主要方法:
- 在接受68Ga-Pentixa治疗的PA患者中,对PET/CT和AVS进行前性招募.
- 随机选择手术可接受的患者进行部分或全部上腺切除术.
- 使用术后阿尔多激素外科结果 (PASO) 标准评估功能性结果.
主要成果:
- 68Ga-Pentixafor PET/CT在预测手术成功方面显示出与AVS相似的准确性 (例如,部分/完全成功的78.89%和74.44%).
- 68Ga-Pentixa对PET/CT的较高SUVmax是完全临床成功的独立预测指标 (AUC0.896,截止值9.8).
- 对于SUVmax>9.8的部分和总上腺切除术的结果没有显著差异;对于SUVmax<9.8的总上腺切除术有利.
结论:
- 68Ga-Pentixafor PET/CT是一种有价值的工具,用于预测PA中的上腺切除结果,为AVS提供了替代方案.
- SUVmax是一个关键的成像生物标志物,可以指导部分和总上腺切除术之间的选择.
- 这种成像方法支持更有针对性和潜在的更少侵入性治疗策略.

Adrenal Gland Disorders
1.3K
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...

Adrenergic Antagonists: Pharmacological Actions of ɑ-Receptor Blockers
514
α-Adrenergic antagonists, known as α-blockers, exert their effects by inhibiting α-adrenoceptors, leading to specific physiological actions. α1-blockers and α2-blockers have distinct pharmacological actions and therapeutic applications.
α1-blockers: These drugs inhibit α1-adrenoceptors on smooth muscle cells, resulting in vasodilation. This vasodilation lowers blood pressure, making α1-blockers valuable in treating hypertension. Additionally,...

Anatomy of the Adrenal Glands
1.8K
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...

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...

Adrenergic Agonists: Therapeutic Uses
693
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.
