Nephropathy due to radiocontrast media presents with a wide spectrum of changes from reversible renal dysfunction to oliguria requiring dialysis. Nineteen patients (mean age 4.5 +/- 3.7 years) were included. Mean +/- SD values of the variables obtained before and 48 hours after angiography were the following: plasma creatinine: 0.6 +/- 0.10 and 0.6 +/- 0.16 mg/dl; endogenous creatinine clearance: 76.1 +/- 17.0 and 80.9 +/- 19.3 ml/min/1.73 m2; plasma osmolality: 279 +/- 23 and 298 +/- 39 mOsm/kg H2O; urine osmolality: 429 +/- 225 and 459 +/- 196 mOsm/kg H2O; fractional sodium excretion: 2.1 +/- 1.3% and 2.4 +/- 1.3%; plasma uric acid: 3.9 +/- 1.3 and 3.4 +/- 1.0 mg/dl; urinary AST/creatinine: 5.2 +/- 4.8 and 4.2 +/- 2.6 mU/mg; ALT/creatinine: 16.8 +/- 12.4 and 15.3 +/- 12.6 mU/mg; LDH/creatinine: 52.0 +/- 39.6 and 42.3 +/- 31.5 mU/mg; NAG/creatinine: 20.1 +/- 2.8 and 16.8 +/- 2.3 mU/mg, respectively. The changes in renal function parameters and urinary enzyme levels were insignificant statistically (p > 0.05). In conclusion, iopromid injection at maximum doses of 5 ml/kg does not result in injury to the tubular epithelium leading to increased urinary enzyme levels.

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.

The role of urinary biomarkers of kidney injury in the prediction of adverse clinical outcomes in acute renal failure (ARF) has not been well described. The relationship between urinary N-acetyl-beta-(D)-glucosaminidase activity (NAG) and kidney injury molecule-1 (KIM-1) level and adverse clinical outcomes was evaluated prospectively in a cohort of 201 hospitalized patients with ARF. NAG was measured by spectrophotometry, and KIM-1 was measured by a microsphere-based Luminex technology. Mean Acute Physiology, Age, Chronic Health Evaluation II (APACHE II) score was 16, 43% had sepsis, 39% required dialysis, and hospital mortality was 24%. Urinary NAG and KIM-1 increased in tandem with APACHE II and Multiple Organ Failure scores. Compared with patients in the lowest quartile of NAG, the second, third, and fourth quartile groups had 3.0-fold (95% confidence interval [CI] 1.3 to 7.2), 3.7-fold (95% CI 1.6 to 8.8), and 9.1-fold (95% CI 3.7 to 22.7) higher odds, respectively, for dialysis requirement or hospital death (P < 0.001). This association persisted after adjustment for APACHE II, Multiple Organ Failure score, or the combined covariates cirrhosis, sepsis, oliguria, and mechanical ventilation. Compared with patients in the lowest quartile of KIM-1, the second, third, and fourth quartile groups had 1.4-fold (95% CI 0.6 to 3.0), 1.4-fold (95% CI 0.6 to 3.0), and 3.2-fold (95% CI 1.4 to 7.4) higher odds, respectively, for dialysis requirement or hospital death (P = 0.034). NAG or KIM-1 in combination with the covariates cirrhosis, sepsis, oliguria, and mechanical ventilation yielded an area under the receiver operator characteristic curve of 0.78 (95% CI 0.71 to 0.84) in predicting the composite outcome. Urinary markers of kidney injury such as NAG and KIM-1 can predict adverse clinical outcomes in patients with ARF.
