概括
某些免疫球蛋白产品,如Privigen,可以暂时增加 (1-3) -β-D-葡萄糖水平在接受全原造血细胞移植 (allo-HCT) 的患者. 这一发现对于在接受免疫球蛋白替代疗法 (IgRT) 的患者中解释诊断生物标志物结果至关重要.
科学领域:
- 生物化学 生物化学
- 免疫学 免疫学 免疫学
- 医学诊断 医学诊断 医学诊断
背景情况:
- (1-3)-β-D-葡萄糖是真菌细胞壁的组成部分,也是侵入性真菌感染的生物标志物.
- 异质造血细胞移植 (allo-HCT) 接受者经常接受免疫球蛋白替代疗法 (IgRT).
- 不同IgRT产品对血清β-D-葡萄糖水平的影响在很大程度上仍未被描述.
研究的目的:
- 为了研究不同免疫球蛋白产品对alo-HCT患者血清β-D-葡萄糖水平的影响.
- 评估IgRT后血清β-D-葡萄糖和IgG水平变化之间的相关性.
主要方法:
- 在接受IgRT (2021-2024) 的allo-HCT患者的血清β-D-葡萄糖水平的回顾性分析.
- 纳入标准:IgRT前后7天内测量的血清β-D-葡萄糖.
- 在不同类型的免疫球蛋白产品中评估β-D-葡萄糖水平的变化,并评估效应大小.
主要成果:
- 分析了125次IgRT (Privigen,Venoglobulin,Venilon-I) 的使用情况.
- 普利维根的使用导致血清β-D-葡萄糖的显著增加 (大效果大小,p < 0.01),在~3周后恢复到基线.
- 温球蛋白或威尼隆-I时没有观察到β-D-葡萄糖的显著变化;Privigen是水平升高的独立因素.
结论:
- 不同的免疫球蛋白产品对IgRT后的血清β-D-葡萄糖水平产生不同的影响.
- 选择免疫球蛋白产品可能会影响解释β-D-葡萄糖作为真菌感染生物标志物.

Hypoglycemia and Glucagon
1.1K
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...

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
722
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
