However, a late sample is not always feasible, for example, in patients treated with peritoneal dialysis (7 days per week) or frequent hemodialysis (4-7 days per week).

This is a comment on "Plasma Iohexol Clearance for Assessing Residual Kidney Function in Dialysis Patients." Am J Kidney Dis. 2015 Oct;66(4):728-30. Determination of residual renal function with iohexol clearance in hemodialysis patients. Kidney Int. 1996; 49:232–235.

Classically, urea (molecular wt 5 60) is used to determine the urea reduction ratio (URR) or clearance, based on volume of distribution (Kt/V). These methods are subject to many errors. The purpose of this study was to determine whether Sterner, G & Prütz, K-G 2016, ' Plasma clearance of iohexol in hemodialysis patients requires prolonged blood sampling ', American Journal of Kidney Diseases, vol. 67, nr. 5, s.

METHODS: Ten hemodialysis (HD) patients were evaluated. However, a late sample is not always feasible, for example, in patients treated with peritoneal dialysis (7 days per week) or frequent hemodialysis (4-7 days per week). Furthermore, relatively little is known about extrarenal CLiohexol in humans, including its source (presumably hepatic), variability, and dependence on serum iohexol concentrations. 1996-01-01 · The renal clearance of iohexol was evaluated as an alternative method for RRF assessment (iohexol-derived RRF) in hemodialysis patients.

Iohexol clearance for the determination of glomerular filtration rate: 15 years' experience in clinical practice.

The total clearance of iohexol was 70.4 +/- 24.6 ml/min and was very close to dialyzer clearance, as estimated from blood flow and extraction ratio. The plasma iohexol level after dialysis was related to the dose administered, iohexol clearance, and the patients' body weight. We aimed to characterize iohexol, molecular weight 821 Da, clearance during continuous hemofiltration (CH) and continuous hemodialysis (CHD). METHODS: Using an in vitro model, iohexol sieving coefficients (SC) and saturation coefficients (SA) were determined with the M100 membrane at ultrafiltration/dialysate rates of 1, 2, 3, 4, and 6 l/h. Plasma clearance of iohexol in hemodialysis patients requires prolonged blood sampling Sterner, Gunnar LU and Prütz, Karl-Göran LU ( 2016 ) In American Journal of Kidney Diseases 67 (5) .

This could jeopardize estimation of residual kidney function when incremental dialysis is used. The URR and iohexol reduction ratio (IoRR) were also different (0.63+/-0.02 vs. 0.69+/-0.02; P < 0.002) with a urea but not Io rebound (URR30 min 0.59+/-0.02, P < 0.05). Calculated urea clearance (C(urea)), 247+/-21 ml/min, significantly overestimated DDQ C(urea) (157+/-10 ml/min P < 0.001). Total body clearance of iohexol (C mg iodine/ml) was administered to 42 hemodialysis patients following routine HD. A single blood sample was obtained approximately 44 hours later (pre-HD) to determine the plasma clearance of iohexol using x-ray fluorescence methods. The use of iohexol clearance to determine GFR in patients with severe chronic renal failure–A comparison between different clearance techniques.

CONCLUSION: Iohexol clearance is a valid method for measuring GFR in patients at any stages of renal failure. Elimination rate and clearance of the contrast media were measured as indices of their dialyzability. RESULTS: After 4 hours of hemodialysis, 78.4+/-6.5% of iohexol and 72.4+/-6.0% ioxaglate were eliminated. Clearance of iohexol was higher than that of ioxaglate at all sampling times. No severe hemodynamic change nor adverse reaction were observed.

Thus, we believe that properly performed plasma iohexol clearance using long sampling time is a suitable technique for estimating residual kidney function in patients receiving hemodialysis. Determination of residual renal function with iohexol clearance in hemodialysis patients. Author links open overlay panel Suzanne K. Swan 1 Charles E. Halstenson 1 Bertram L. All clearance measurements are reported in mL/min/1.73 m 2, and median [IQR] values were as follows: 24-hour plasma CL iohexol, 7.1 [5.3-9.4]; 4-hour plasma CL iohexol, 12.7 [7.8-18.0]; 24-hour urinary CL iohexol, 2.3 [0.5-4.3]; and 24-hour urinary CL urea,cr, 3.2 [1.6-5.4]. Iohexol clearance determinations are now per-formed at numerous hospitals in Sweden. A national quality assurance program, now including 20 different laboratories, was initiated in 1996. All use versions of the HPLC technique.
