概括

接受治疗的Gaucher病患者的葡萄糖氨酸 (lysos-Gb1) 水平降低,但这些水平仍然很高,这表明疾病活动或炎症正在进行中. 对治疗疗效和疾病机制的进一步研究是有必要的.

科学领域:

生物化学生物化学
遗传学遗传学是一个
医学研究医学研究

背景情况:

氏病 (Gaucher disease,简称GD) 是一种由于β-葡萄糖酶缺乏而导致的溶解体储存障碍.
可用的是疾病修饰疗法 (DMT),如酶替代疗法 (ERT) 和基质减少疗法 (SRT).
葡萄糖氨酸 (lyso-Gb1) 是GD的敏感和特定生物标志物.

研究的目的:

为了评估GD患者的干血斑点lyso-Gb1水平.
根据治疗状态,GD类型,ERT剂量,治疗持续时间和状态来评估lysogb1水平.
探索lyso-Gb1与其他GD生物标志物之间的关联.

主要方法:

在100名GD患者中测量了干血斑点lysogb1水平.
分析包括治疗状态,性别,GD类型/基因型,ERT剂量,DMT持续时间和状况.
检查了与胆三酶和血红蛋白的相关性.

主要成果:

与接受治疗的患者相比,未接受治疗的患者的中位数lyso-Gb1更高 (195 vs 47.1 ng/mL).
接受治疗15年以上的患者的lysogb1比接受治疗15年以下的患者高 (62.9 vs 35.1 ng/mL).
脊髓切除术患者的lysogb1水平 (83.4 ng/mL) 比非脊髓切除术患者 (40.7 ng/mL) 高. 莱索-Gb1与胆三酶正相关,与血红蛋白负相关.
随着时间的推移,在接受DMT的小组患者中观察到lysogb1的适度下降.

结论:

虽然DMT导致lyso-Gb1的适度下降,但水平仍然明显高于正常范围.
持续高的lysogb1可能表明正在进行的炎症或疾病负担.
需要进一步研究导致lysogb1升高的潜在机制,尽管接受了治疗.

关键词:

戈舍氏病是戈舍氏病的一种疾病.生物标志物生物标志物酶替代疗法是一种酶替代疗法.这就是lyso-Gb1的原因.降解疗法是基质的降解疗法.

Lysosomal Hydrolases

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
