概括
将下午晚些时候的皮质醇测量添加到夜间德甲抑制测试 (ODST) 中,可以提高诊断的准确性. 上皮质激素 (ACTH) 测试对于特定的患者群体也是有益的.
科学领域:
- 内分泌学 在内分泌学.
- 临床诊断 临床诊断 临床诊断
- 激素检测测试验 激素检测试验
背景情况:
- 夜间德克萨米他抑制试验 (ODST) 是一种敏感但不完全特定的诊断工具.
- 标准ODST的特异性在80-90%之间,可能导致误诊.
研究的目的:
- 评估是否结合下午晚些时候的皮质醇和ACTH测量可以提高ODST的准确性.
- 评估这些新型测量在各种患者群体中的诊断效用.
主要方法:
- 一项前性研究,涉及健康成年人,口服避孕药使用者,CKD患者和患有ACTH依赖的库辛综合征 (活跃或缓解) 的个人.
- 标准的1毫克ODST进行,在早上8-9点和下午3-4点抽取皮质醇和ACTH的血液样本.
主要成果:
- 大多数组中,下午晚些时候的皮质醇水平明显低于上午水平,除了活跃的库辛综合征.
- 虽然早晨和下午晚些时候的皮质醇在健康个体中表现出高特异性,但在口服避孕药使用者和CKD患者中,其特异性较低.
- 下午晚些时候的ACTH测量显示了健康,口服避孕药和CKD组的高特异性,对于诊断依赖ACTH的库辛综合征的100%灵敏度.
结论:
- 下午晚些时候的皮质醇测量代表了ODST的一个有价值的修改,提高了它的特异性.
- ACTH测量对于区分口服避孕药使用者和CKD患者的病情特别有用.
- 在广泛采用这些增强的ODST协议之前,建议进一步验证.

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

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...
