N-Acetylcysteine to Prevent Radiocontrast Nephropathy in Emergency Department Patients

2014-08-27 03:26:39 | BioPortfolio


Multiple agents have been studied to prevent radiocontrast nephropathy after the administration of radiocontrast agents. One of these agents is N-acetylcysteine. Previous trials to assess the efficacy of n-acetylcystenine in the prevention of contrast nephropathy have been promising.

Previous work in this field has limited applicability to the Emergency Department (ED) patient population for two reasons:

1. Many of the pretreatment strategies employed in these studies take several hours or even days to perform, which is not feasible in acutely ill ED patients.

2. Most of these studies were conducted in patients undergoing cardiac catheterization. This may be a very different population than patients in the ED undergoing abdominal or chest computed tomography.

We wish to study the efficacy of N-acetylcysteine as an agent to prevent radiocontrast nephropathy in ED patients undergoing computerized tomography. We propose a randomized, double-blind, controlled trial comparing saline hydration plus N-acetylcysteine versus saline hydration alone. The hypothesis of this study is that N-acetylcysteine with normal saline will be more effective than saline alone in the prevention of radiocontrast nephropathy.

Medical and Biotech [MESH] Definitions

Renal syndrome in human immunodeficiency virus-infected patients characterized by nephrotic syndrome, severe proteinuria, focal and segmental glomerulosclerosis with distinctive tubular and interstitial changes, enlarged kidneys, and peculiar tubuloreticular structures. The syndrome is distinct from heroin-associated nephropathy as well as other forms of kidney disease seen in HIV-infected patients.

A phenylacetamide that was formerly used in ANALGESICS but nephropathy and METHEMOGLOBINEMIA led to its withdrawal from the market. (From Smith and Reynard, Textbook of Pharmacology,1991, p431)

A form of chronic interstitial nephritis that is endemic to limited areas of BULGARIA, the former YUGOSLAVIA, and ROMANIA. It is characterized by a progressive shrinking of the KIDNEYS that is often associated with uroepithelial tumors.

A plant genus of the family ARISTOLOCHIACEAE. Species of this genus have been used in traditional medicine but they contain aristolochic acid which is associated with nephropathy. These are sometimes called 'snakeroot' but that name is also used with a number of other plants such as POLYGALA; SANICULA; ASARUM; ARISTOLOCHIA; AGERATINA; and others.

Nitro-phenanthrenes occurring in ARISTOLOCHIACEAE and other plants. They derive from stephanine (APORPHINES) by oxidative ring cleavage. The nitro group is a reactive alkylator (ALKYLATING AGENTS) that binds to biological macromolecules. Ingestion by humans is associated with nephropathy (NEPHRITIS). There is no relationship to the similar named aristolochene (SESQUITERPENES).
