The effects on urine and serum profiles of intravenous injection of diatrizoate, iohexol, or saline were studied in male rats pretreated with steroids or saline. Using urinary albumin, glucose, sodium, and the enzymes lactate dehydrogenase (LDH), gamma-glutamyltransferase (GGT), and N-acetyl-beta-D-glucosaminidase (NAG) as markers of glomerular and tubular function, it was found that diatrizoate caused temporary glomerular and tubular dysfunction; the effect was independent of the kind of pretreatment. Iohexol did not cause increased glomerular permeability in steroid- and saline-pretreated rats. When used following saline, iohexol induced increased excretion of three tubular components, whereas iohexol plus steroids caused increased excretion of all five tubular components. The dysfunctional effect of iohexol plus steroids was less than that of diatrizoate plus steroids. The serum components revealed no abnormalities induced by either contrast media or methylprednisolone. Pretreatment with steroids has no effect on the glomerular or tubular dysfunctional effect of diatrizoate, whereas it worsens the temporary tubular dysfunctional effect of iohexol in rats.

The effects of intravenous diatrizoate, iohexol, ioxilan, or saline on albumin, glucose, sodium and the enzymes N-acetyl-beta-D-glucosaminidase (NAG), lactate dehydrogenase (LDH), and L-gamma-glutamyltransferase (GGT) in the urine of 24 normal Wistar rats were followed for seven days. During the first two hours after administration of diatrizoate, all profile components changed markedly; the albumin excretion was significantly greater than following ioxilan and iohexol; glucose, LDH, and GGT excretions were significantly greater than following ioxilan. Iohexol and ioxilan caused a higher excretion of albumin, LDH, and GGT than saline. Iohexol also increased glucose and sodium levels. Glucose and GGT were significantly higher following iohexol than following ioxilan. Both high osmolar and low osmolar contrast media may cause temporary glomerular and tubular damage. Urine profile components are affected most by diatrizoate, less by iohexol, and least by ioxilan.

We assessed the nephrotoxicity of a non-ionic contrast medium, Iohexol, in 18 elderly patients. They were divided into two groups. Group 1 consisted of 12 patients with glomerular flow rate (GFR) above 60 ml/min/1.73 m2 (range 69-136; average 96) and group 2 consisted of 6 patients with GFR below 60 ml/min/1.73 m2 (range 38-59; average 49). Urine samples, collected before, immediately after, and on the third and sixth days after drip infused pyeloureterography (DIP) were analyzed for gamma-glutamyl transpeptidase (gamma-GTP), N-acetyl-beta-D-glucosaminidase (NAG), beta 2-microglobulin (beta 2-MG) and albumin. In group 1, immediately after DIP, the urinary excretion of albumin, gamma-GTP and NAG were significantly increased (p < 0.01, p < 0.01, p < 0.01). In group 2, immediately after DIP, the urinary excretion of gamma-GTP and beta 2-MG were significantly increased (p < 0.01, p < 0.1). The gamma-GTP and NAG values in both groups suggest that the damage of proximal tubules cells will not continue for more than 4 days. However, as for the reabsorption of beta 2-MG on proximal tubules, in group 2 the value did not return to the pre DIP level until 6 days after DIP. We believe it is important to postpone injection of non-ionic contrast medium within 6 days of its last usage.
