概括
接受胰岛素治疗的孕期糖尿病 (GDM) 的母亲的新生儿在出生时表现出明显的尿路代谢概况. 这些早期生物标志物可能有助于监测婴儿,并预测未来的慢性疾病风险.
科学领域:
- 代谢学 代谢学 代谢学
- 新生儿健康 新生儿健康
- 内分泌学 在内分泌学.
背景情况:
- 孕期糖尿病 (GDM) 对胎儿和新生儿的健康有风险.
- 无法控制的GDM可能会导致后代长期的健康问题,包括肥胖和2型糖尿病.
- 在糖尿病母亲 (NDM) 的新生儿中识别早期生物标志物对于监测和早期诊断至关重要.
研究的目的:
- 使用NMR和GS-MS分析糖尿病母亲 (NDMs) 新生儿的尿道代谢概况.
- 确定潜在的生物标志物来监测NDM和预测慢性疾病倾向.
- 为了比较接受饮食治疗与胰岛素治疗的母亲和对照组的婴儿之间的代谢概况.
主要方法:
- 使用了核磁共振 (NMR) 光谱和气色谱-质谱 (GS-MS).
- 分析了来自26名新生儿的尿样 (21名新生儿,5名对照) 在出生至产后六个月的五个时间点.
- NDMs被分为饮食治疗 (NDM-饮食) 和胰岛素治疗 (NDM-胰岛素) 组.
主要成果:
- 在出生时 (T1),与NDM饮食和对照婴儿相比,在NDM胰岛素婴儿中观察到七种尿代谢物的显著变化.
- 改变的代谢物包括乙酸盐,乳酸盐,甘氨基/,异酸盐,N,N-二甲基甘氨酸,N-乙糖胺和N-碳酸.
- 这些代谢变化与酸盐,甘氨酸,血清,三氨酸,氨酸,氨酸,氨酸,氨基糖,核酸糖和酸盐代谢等途径有关,但在以后的时间点没有出现.
结论:
- 在胰岛素治疗中患有GDM的母亲的婴儿出生时,特定的尿路代谢概况可以作为早期指标.
- 这些发现表明这些婴儿的慢性疾病风险监测和早期诊断的潜在生物标志物.
- 早期营养 (母体和配方) 被认为是影响这些早期代谢差异的潜在因素.

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...

Pathophysiology of Diabetes

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,...
