Renal Effects of Two Iodinated Contrast Media in Patients at Risk Undergoing Computed Tomography
Summary
It is well known that X-ray contrast media can affect kidney function in some patients, especially when administered intra-arterially, and patients who already suffer from reduced kidney function and diabetes mellitus may be at increased risk. It is widely accepted to use low-osmolar or iso-osmolar contrast media, especially in patients at risk for contrast media-induced nephropathy. However, little is known about the intravenous use of X-ray contrast media in risk patients, such as contrast-enhanced CT examinations. The main purpose of this study is to evaluate and compare the effects on kidney function of two contrast media, the iso-osmolar iodixanol and the low-osmolar iopamidol in patients at risk of kidney damage associated with the injection of contrast media. Due to the iso-osmolar feature, it is expected less influence on renal function following administration of iodixanol. A standard hydration procedure, based on available guidelines will be given to all patients to prevent negative effects on the kidneys. Serum creatinine (SCr ) concentrations will be measured before and up to 7 days after contrast media administration to evaluate the effects on renal function.

Medical and Biotech [MESH] Definitions
Renal Insufficiency
Conditions in which the KIDNEYS perform below the normal level in the ability to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal insufficiency can be classified by the degree of kidney damage (as measured by the level of PROTEINURIA) and reduction in GLOMERULAR FILTRATION RATE. The most severe form is KIDNEY FAILURE. Renal function may deteriorate slowly (RENAL INSUFFICIENCY, CHRONIC) or precipitously (RENAL INSUFFICIENCY, ACUTE).
Nephrocalcinosis
A condition characterized by calcification of the renal tissue itself. It is usually seen in distal RENAL TUBULAR ACIDOSIS with calcium deposition in the DISTAL KIDNEY TUBULES and the surrounding interstitium. Nephrocalcinosis causes RENAL INSUFFICIENCY.
Renal Insufficiency, Chronic
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)
Uranyl Nitrate
Bis(nitrato-O)dioxouranium. A compound used in photography and the porcelain industry. It causes severe renal insufficiency and renal tubular necrosis in mammals and is an effective lymphocyte mitogen.
Cardio-renal Syndrome
Condition where a primary dysfunction of either heart or kidney results in failure of the other organ (e.g., HEART FAILURE with worsening RENAL INSUFFICIENCY).
