The nephrotoxic potentials of a high-osmolar contrast medium, diatrizoate, and of a low-osmolar contrast medium, ioxaglate, were compared during early degenerative gentamicin-induced nephropathy in the rat. Male rats (13-22/group) were uninephrectomized. Six days later, the aorta was clamped above the renal artery, and either diatrizoate or ioxaglate was administered (1 ml/min for 3 min) via an aortic puncture into the remaining kidney. Some of the rats received chronic treatment with gentamicin (50 mg/kg/day i.m., 4 days), starting 2 days before and ending 1 day after contrast medium administration. Two control groups, only one of which received gentamicin, were subjected to a 3-min renal ischemia. The creatinine clearance (CrCl) per 100 g body weight was determined before and 24 and 48 h after contrast medium injection. A second study (6 rats/group) evaluated urinary N-acetyl-beta-D-glucosaminidase (NAG) excretion and the histologic appearance of the kidneys (blinded analysis) in the same experimental groups. Gentamicin induced a significant decrease in CrCl at baseline (0.35 +/- 0.19 vs. 0.41 +/- 0.19 ml/min; p < 0.01) and an increase in urinary NAG (128 +/- 92 vs. 39 +/- 57 mumol/h/mmol creatinine; p < 0.01). Taking into account these differences at baseline, univariate repeated-measures analysis showed that on day 1 diatrizoate caused a more marked decrease in CrCl than ioxaglate (p < 0.05), whether or not gentamicin was also administered. On day 2, the depressant effect of diatrizoate associated with gentamicin persisted (CrCl vs. day 0 = -0.19 +/- 0.10 ml/min), while that of diatrizoate alone returned to baseline (-0.05 +/- 0.24 ml/min).(ABSTRACT TRUNCATED AT 250 WORDS)
