iothalamate-meglumine and Kidney-Tubular-Necrosis--Acute

Twenty-one patients slated for high-dose arteriography were studied to investigate the impact of predisposing medical conditions upon contrast medium induced acute renal failure. The study suggests that predisposing medical conditions are the most important factor determining the incidence of acute renal failure and the probability, speed, and degree of recovery of renal function. Patients with diabetes mellitus incur the highest risk of contrast medium induced acute renal failure. A dose relationship is also suggested. Contrast medium doses containing more than 100 g of iodine uniformly produced acute tubular necrosis in patients with predisposing medical conditions. Conversely, contrast medium doses containing less than 80 g of iodine produced clinically manifest acute renal failure in only one of 14 patients with predisposing medical conditions. Subclinical levels of acute renal failure were recognized in a large number of patients by routine measurement of radionuclide filtration fractions, serum creatinine levels, and urine osmolality and sodium concentration.
