概括
染细胞瘤和状细胞瘤 (PPGLs) 中的二次糖尿病 (DM) 源于瘤诱导的代谢变化. 手术切除这些瘤显著改善或消除了二次DM,这表明涉及非上腺机制.
科学领域:
- 内分泌学 在内分泌学.
- 代谢障碍 代谢障碍 代谢障碍
- 在瘤学瘤学.
背景情况:
- 二次性糖尿病 (DM) 影响了多达50%的分泌性血红细胞瘤和横瘤 (PPGLs) 患者.
- PPGLs诱导高代谢状态,通过上腺体机制导致胰岛素抵抗,影响糖解,脂解和激素分泌.
- 在PPGL中,二次性DM的表现从轻微的胰岛素耐药性到严重的状态,如糖尿病酸性脂肪酸症,各不相同.
研究的目的:
- 为了阐明PPGL中二次DM的发病因子.
- 探索瘤表型对血糖控制的影响.
- 评估手术干预的有效性,并确定有助于DM改善的潜在非上腺体机制.
主要方法:
- 对PPGLs和二次DM的现有文献的审查.
- 分析甲醇胺对葡萄糖代谢和胰岛素分泌的直接和间接影响.
- 术后结果与药物阻断的比较.
主要成果:
- 由PPGLs分泌的上腺素和上腺素会通过上腺刺激和改变的代谢途径引起胰岛素抵抗.
- 瘤表型影响胰岛素分泌,上腺瘤会损害胰岛素分泌,而上腺瘤可能会增强胰岛素分泌,从而导致不同的葡萄糖表型.
- 手术导致二次DM的实质性改善,有高达80%的缓解率,表明除上腺阻塞之外的机制.
结论:
- 在PPGL中,二次性DM是由瘤分泌物诱导的复杂代谢变化驱动的.
- 手术治疗在治疗二次DM方面非常有效,突出显示了瘤切除的重要性.
- 需要进一步的研究来探索非上腺作用的机制,并评估针对PPGL相关的DM的新型抗糖尿病药物.

Hypoglycemia and Glucagon
287
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...

Adrenal Gland Disorders
1.6K
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...

Diabetes Mellitus: Type 2 and Gestational
2.5K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
1.3K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are...

Pathophysiology of Diabetes
971
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
