概括
患有上腺意外瘤 (AIs) 的患者可能因皮质醇过量而面临骨折风险增加. 这项研究表明了潜在的联系,虽然在统计学上并不显著,但强调了需要更好地识别激素活性AI.
科学领域:
- 内分泌学 在内分泌学.
- 骨的新陈代谢 骨的新陈代谢
- 老年医学 老年医学
背景情况:
- 上腺意外瘤 (AIs) 可以高分泌皮质醇,导致过度暴露于葡萄糖皮质激素.
- 这种过量的皮质醇可能会降低骨矿物质密度,增加骨折风险.
- 在AI患者中,皮质醇过量往往无法测量,导致骨折风险的诊断不足.
研究的目的:
- 调查过多的皮质醇水平与AI患者的脆弱性骨折发生率之间的关联.
- 为了确定患有AI和亚临床皮质醇过剩的患者是否有更高的骨折风险.
主要方法:
- 对14886名患有AI的50岁以上患者进行了回顾性队列研究 (2015-2022年).
- 基于德甲抑制试验 (DST) 和尿液/血清皮质醇水平的皮质醇过量状态的分类.
- 使用考克斯的比例危险模型分析骨折发生率,对共变量进行调整,并将死亡率视为竞争风险.
主要成果:
- 1.8%的患者通过DST确认了自主皮质醇分泌 (ACS);1.4%的患者从其他测试中显示了有意义的结果.
- 62.8%的患者没有接受过多的皮质醇检测.
- 患有ACS,暗示皮质醇过量或未经测试的病情的患者表现出增加骨折风险的趋势 (HR分别为1.42,1.41和1.28),但这些并没有达到统计学意义.
结论:
- 虽然趋势表明上腺瘤和皮质醇过量患者的骨折风险较高,但这些发现在统计学上并不显著.
- 在未经测试的患者中观察到的高风险可能表明大量未被诊断的,荷尔蒙活性AI有助于二次骨质疏松症.
- 需要进一步的研究来证实这些关联,并改善AI管理中皮质醇过剩的诊断策略.

Adrenal Gland Disorders
1.2K
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...

Hormones of the Adrenal Glands
2.0K
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...

Bone Disorders
3.3K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hypothalamic-Pituitary Axis
58.3K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Anatomy of the Adrenal Glands
1.7K
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...

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...
