The Effects of AST-120 on Endothelial Dysfunction in Patients With Chronic Kidney Disease

2014-08-27 03:12:24 | BioPortfolio


Indoxyl sulfate (IS) is a uremic toxin that accelerates the progression of chronic kidney disease (CKD). AST-120 (Kremezin®; Kureha Corporation, Tokyo, Japan) removes indole, which is the precursor of IS, in the intestine, and reduces the accumulation of IS. This drug has been shown to retard the deterioration of renal function in CKD patients through reducing the levels of IS.

IS was reported to promote aortic calcification and stimulate the proliferation of vascular smooth muscle cells (VSMC). IS also inhibits endothelial proliferation and wound repair. With this background, the investigators will performed the study whether AST-120 improve the endothelial dysfunction in CKD patients.


The purpose of this study is to examine whether Kremezin, Indoxyl sulfate lowering agent improve endothelial dysfunction in stage 3,4 chronic kidney disease patients

Medical and Biotech [MESH] Definitions

A severe irreversible decline in the ability of kidneys to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal failure, either acute (KIDNEY FAILURE, ACUTE) or chronic (KIDNEY FAILURE, CHRONIC), requires HEMODIALYSIS.

The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

Conditions in which the KIDNEYS perform below the normal level for more than three months. Chronic kidney insufficiency is classified by five stages according to the decline in GLOMERULAR FILTRATION RATE and the degree of kidney damage (as measured by the level of PROTEINURIA). The most severe form is the end-stage renal disease (CHRONIC KIDNEY FAILURE). (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002)

A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.

Sudden liver failure in the presence of underlying compensated chronic LIVER DISEASE (e.g., LIVER CIRRHOSIS; HEPATITIS; and liver injury and failure) due to a precipitating acute hepatic insult.
