NASPI: N-Acetylcysteine vs. Ascorbic Acid for Prevention of Contrast Induced Nephropathy in Renal Insufficiency Undergoing Coronary Catheterization

2014-08-27 03:43:20 | BioPortfolio

Summary

The contrast induced nephropathy (CIN) has been known to be associated with significant clinical and economic consequences. Many studies were performed to find the pathophysiology and preventive measures for CIN. But the results were somewhat frustrating. Recently, it has been reported that the N-acetylcysteine and ascorbic acid might have preventive effects for CIN by their antioxidant effects.There have been no study to compare these two antioxidant.

Description

N-acetylcysteine and ascorbic acid may prevent the CIN in the patients with underlying renal insufficiency who is undergoing the coronary angiography. The effect may derive from the antioxidant function of these two antioxidant. We studied to find which of the two antioxidants is more beneficial in prevention of CIN

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.

A condition due to a dietary deficiency of ascorbic acid (vitamin C), characterized by malaise, lethargy, and weakness. As the disease progresses, joints, muscles, and subcutaneous tissues may become the sites of hemorrhage. Ascorbic acid deficiency frequently develops into SCURVY in young children fed unsupplemented cow's milk exclusively during their first year. It develops also commonly in chronic alcoholism. (Cecil Textbook of Medicine, 19th ed, p1177)

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.

A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.

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.
