Effects on renal haemodynamics and tubular function of the contrast medium Ioxaglate in renal transplant patients.
The aim of this study was to evaluate the effects of Ioxaglate on renal haemodynamics and tubular function in renal transplant patients at increased risk of nephrotoxicity. 21 patients undergoing either intravenous pyelography or arteriography with Ioxaglate were studied. Renal clearance studies were carried out 1 day before and 1 day after administration of Ioxaglate (173 +/- 37 ml) injected into each patient. None experienced any adverse reaction. Mean serum creatinine, glomerular filtration rate (GFR), effective renal plasma flow (ERPF) and urinary NAG excretion were unaltered by ioxaglate. No patient suffered a nephrotoxic reaction or acute oliguria that required dialysis as a result of the administration of contrast material. In the subset of seven patients receiving cyclosporine the same results were observed. In the subset of 10 patients with a GFR lower than 60 ml/min before injection of Ioxaglate were also observed no significant change in mean GFR, ERPF and urinary NAG excretion. Only two patients had a transient decrease of GFR of between 10 and 20%. The results of this study show that the ionic, low osmolar contrast medium ioxaglate may be used safely in patients with a renal transplant thus extending previous data obtained in patients with chronic renal failure.
