概括

高压液体染色学 (HPLC) 在慢性病 (CKD) 患者中准确测量HbA1c,与度抑制免疫试验 (TINIA) 不同,度抑制免疫试验在贫血患者中失败. 建议使用HPLC进行可靠的糖尿病监测.

科学领域:

临床化学临床化学
腎臟病學 (nephrology) 是一種醫學專業.
内分泌学在内分泌学.

背景情况:

慢性病 (CKD) 在监测血糖控制方面存在挑战,特别是在糖尿病患者中.
慢性病患者的贫血和尿血使得血红蛋白A1c (HbA1c) 的准确测量变得复杂.

研究的目的:

为了比较度抑制免疫试验 (TINIA) 和高压液体染色学 (HPLC) 对非透析CKD患者HbA1c测量的性能.
在这个人群中确定影响HbA1c测量精度的因素.

主要方法:

进行了一项分析横截面研究,对127名非透析CKD患者进行了分析.
使用TINIA和HPLC方法测量HbA1c水平.
分析了两种方法之间的相关性和一致性,以及贫血和碳amylated血红蛋白 (CHb) 的影响.

主要成果:

在27%的贫血患者中,TINIA未能检测到HbA1c,而HPLC为所有患者提供了可测量的结果.
在100名患者中,在TINIA和HPLC之间观察到强烈的正相关性 (R2=0.861) 和实质性一致性 (科恩卡帕0.657),这两种方法都产生了结果.
与TINIA相比,HPLC报告了糖尿病CKD患者的HbA1c水平显著更高. 碳氨基化血红蛋白 (CHb) 与HbA1c测量和血清尿素水平相关.

结论:

在CKD患者,特别是贫血患者中,HPLC在HbA1c测量方面优于TINIA,因为它提供了完整的评估.
由于低血红蛋白和高碳amylated血红蛋白等因素的干扰,TINIA低估了糖尿病CKD患者的HbA1c.
在CKD中精确的HbA1c监测需要对贫血和其他生化变化的强有力的方法.

Renal Drug Clearance: Comparison Between Renal Excretion Methods

Renal Drug Clearance: Comparison Between Renal Excretion Methods

Renal clearance is a critical parameter encompassing kidney filtration, secretion, and reabsorption processes. It is calculated using a specific equation to determine the rate at which the kidneys clear a drug.
Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...

Drug Dosing in Renal Diseases: Measurement of Glomerular Filtration Rate

The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area. This equation is...
