Hemodialysis Patients without Urine Collection', Seminars in with KRU in haemodialysis patients to see if iohexol clearance can be used to substitute KRU.

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. 811.

Tom C Zwart Department of Clinical Pharmacy and Toxicology, Leiden University Medical Center, Albinusdreef 2, 2333ZA, Leiden, the Netherlands. The average deviation between Iohexol and (99m)Tc-DTPA clearance was 7.4 ml/min/1.73 m2. Allergic and nephrotoxic side effects were not observed. 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.

This result agrees with data from anuric patients for whom extrarenal iohexol clearance was measured between 2 hemodialysis sessions. 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.

BibTex; Full citation Publisher: 'Springer Science and Determination of residual renal function with iohexol clearance in The blood clearance of iosimenol during clinical hemodialysis was predicted as, on average, approximately 85 mL/min with the high-flux membranes and 47 mL/min with the low-flux membrane. Conclusion The dialyzability of iosimenol was evaluated using a newly developed in vitro dialysis system, and iosimenol was readily cleared from blood with all four tested membranes.

Comparison of iohexol and 51Cr-EDTA clearances 1177.

The `apparent' mass of iohexol, defined as plasma concentration times estimated distribution volume, fell to 29% and 21% of pre-dialysis levels after 3 h and 6 h HD, respectively (P <0.01), but increased after HD, and more so after the short dialysis, reaching 46% of the predialysis mass 24 h after 3 h HD vs 36% after 6 h HD (P <0.05).

We read with interest the recent article by Shafi et al1 reporting discrepancies between plasma and urinary clearance of iohexol in dialysis patients. 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).

Tom C Zwart Department of Clinical Pharmacy and Toxicology, Leiden University Medical Center, Albinusdreef 2, 2333ZA, Leiden, the Netherlands.

The obtained results were qualitatively similar to those obtained by analysis of the dialysate but those measurements had a higher variability.

No severe hemodynamic change nor adverse reaction were observed. First studies in humans documenting biochemical properties and pharmacokinetics parameters (15-18) showed that iohexol is excreted unchanged in urine and its renal clearance is almost identical to 51 Cr-EDTA clearance. The reliability of GFR determination by iohexol plasma clearance was demonstrated a few years later by Krutzén et al.

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) . p.811-811

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.
