背景情况:
- 使用先进树脂的血液吸收 (HA) 弹被开发用于增加透析期间的毒素去除.
- 这些弹,当与透析器一起使用时,旨在改善除了传统的扩散和对流之外的尿素毒素的消除.
- 这项研究调查了HA在血液透析 (HD) 和血液过 (HDF) 中对广泛的溶液,包括与蛋白质结合的毒素的疗效.
研究的目的:
- 评估血液吸收 (HA) 盒子在血液透析 (HD) 和血液过 (HDF) 过程中增强各种分子量溶液的去除效果.
- 为了比较不同透析方式的溶液去除效率,包括低流量HD (LFHD),高流量HD (HFHD) 和稀释后HDF,加和不加HA.
- 评估HA对蛋白质结合尿性毒素的清除的影响,这些毒素很难通过常规透析去除.
主要方法:
- 这是一项前性研究,涉及20名接受过六次透析的患者.
- 透析方式有系统地变化,包括低流量HD (LFHD),LFHD与HA (LFHD-HA),高流量HD (HFHD),HFHD与HA (HFHD-HA),稀释后HDF和HDF与HA (HDF-HA).
- 保持了常规治疗参数,只有透析方式在每次会议之间被改变.
主要成果:
- 血液过 (HDF) 治疗,有或没有HA,与LFHD和HFHD相比,显示出更高的尿素和肌氨酸减少比率 (RR).
- 在相同的治疗模式内,添加HA并没有显著改变小分子去除.
- 与单独使用LFHD相比,LFHD-HA显示了β2-微型球蛋白,肌球蛋白,益乳素和羔羊无免疫球蛋白轻链 (λFLC) 的RR增加. 与单独使用HFHD相比,HFHD-HA同样增加了肌球蛋白,α1-微球蛋白和λFLC的RR.

Dialysis
561
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Filtration and Urine Formation
49.1K
The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys.

Renal Drug Excretion: Glomerular Filtration
116
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
55
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...

Heart Failure Drugs: Diuretics
313
Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Methods for Studying Drug Absorption: In situ
191
In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
