概括
估计的膜过率 (eGFR) 方程很难预测脏捐赠者的测量GFR (mGFR). 技术-99m二乙烯-三胺-五乙酸盐 (99mTc-DTPA) 剪影是捐赠后功能更好的指标.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 核医学就是核医学.
- 移植医学 移植医学
背景情况:
- 脏捐赠者接受功能评估,以确保捐赠者的安全和接受者的结果.
- 技术-99m二乙烯-三胺-五乙酸盐 (99mTc-DTPA) 光学是测量膜过率 (mGFR) 的验证方法.
- 现有的方程估计GFR (eGFR),但它们在脏捐赠者中的准确性需要评估.
研究的目的:
- 为了比较常用的eGFR方程与99mTc-DTPA光谱基的mGFR在脏捐赠者的准确性.
- 评估捐赠后一年的mGFR趋势.
- 为了确定这个特定人群中mGFR的最佳预测方程.
主要方法:
- 34名脏捐赠者被招募并被跟踪了一年.
- 测量GFR (mGFR) 用99mTc-DTPA光学扫描在捐赠前和捐赠后确定.
- 估计的GFR (eGFR) 用MDRD,CKD-EPI和Nankivell方程计算,并与mGFR进行比较.
主要成果:
- 测量GFR (mGFR) 在捐赠后的残留脏中增加了32.3%.
- 在正常体重和超重的捐赠者之间没有观察到mGFR的显著差异.
- 所有测试的eGFR方程都显示与mGFR的相关性和一致性较差,具有显著的偏差和差异.
结论:
- 通常使用的eGFR方程对于评估印度脏捐赠者的功能是不可靠的.
- 与eGFR方程相比,99mTc-DTPA光学图提供了对mGFR的更准确的评估.

Renal Clearance
780
The glomerular filtration rate (GFR) is a critical marker of kidney function, reflecting the efficiency of filtration by the glomeruli. Renal clearance of specific substances, such as inulin or creatinine, is commonly used to measure GFR.
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...

Factors Affecting Renal Clearance: Renal Impairment
59
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Kidney Transplant I: Introduction
2
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Renal Drug Excretion: Glomerular Filtration
192
The kidney serves as the primary organ responsible for eliminating drugs and their metabolites from the body. This process, known as renal elimination, starts with glomerular filtration and results in urine formation. Each kidney houses millions of functional units called nephrons, where urine production occurs. A nephron has two main components: a renal corpuscle and a renal tubule.
Drugs gain access to the kidney via the renal artery, which progressively branches off into afferent arterioles....

Renal Drug Clearance: Comparison Between Renal Excretion Methods
83
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...

Determination of Renal Drug Clearance: Graphical and Midpoint Methods
83
Renal clearance, a crucial parameter in pharmacokinetics, can be determined using two different methods: the graphical method and the midpoint method. These methods provide insights into the rate of drug excretion by the kidneys and aid in assessing renal function.
The graphical method involves plotting the rate of drug excretion in urine against the plasma drug concentration. By analyzing the graph, the clearance can be calculated and obtained. Drugs rapidly excreted by the kidneys exhibit a...
