概括
腹腔外科手术 (BS) 可以影响德甲抑制测试 (DST) 结果,导致皮质醇水平升高和手术后血德甲度降低. 这可能会导致患者出现错误的DST结果.
科学领域:
- 内分泌学 在内分泌学.
- 代谢手术 代谢手术
背景情况:
- 1毫克德甲抑制试验 (DST) 用于诊断库辛综合征.
- 减肥手术 (BS) 对DST表现的影响尚未得到充分证实.
- 肥胖本身可能会影响DST结果.
研究的目的:
- 评估腹手术 (BS) 之前和之后的个体内DST结果.
- 评估血中德克萨米他水平和其他影响DST可靠性的因素BS后.
- 为了比较后BS患者,严重肥胖个体和健康对照的DST结果.
主要方法:
- 在BS之前和BS后2年接受DST的38名受试者的前性纵向研究.
- 在BS后的患者 (n=21),没有BS的严重肥胖患者 (pwO,n=10) 和健康对照者 (n=7) 之间比较DST结果和血中德克萨米他水平.
- 多变量分析以确定血甲松度的预测因素.
主要成果:
- 与BS前患者相比,BS后患者在DST后表现出更高的皮质醇水平 (0.9比0.7μg/dL).
- 四名BS后患者的皮质醇升高 (>1.8μg/dL) 没有自主皮质醇分泌.
- 在BS后的患者中,血中甲松水平显著降低 (1.9 ng/dL),而不是pwO (3.7 ng/dL) 和对照 (4.0 ng/mL).
- 腹腔外科手术 (BS) 和性激素结合环球蛋白水平独立预测了较低的血甲松度.
结论:
- 腹部外科手术后的患者表现出改变的DST结果,皮质醇水平较高,德甲水平较低,可能导致错误阳性.
- 在BS后的患者中,应考虑测量甲以准确解释DST.
- 需要进一步的研究来验证这些发现,并探索潜在的机制.

Hypoglycemia and Glucagon
143
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
34
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

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...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
91
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
