ProtocoL for GFR Measurement Using Iohexol (SCOPE-PLUS) - A Substudy of the Calculation of GFR and Validity Compared to the Renal Clearance of Inulin.

Objective—To develop a formula for correcting slope-intercept plasma iohexol clearance in cats and to compare clearance of total iohexol (TIox), endo-iohexol (EnIox), and exo-iohexol (ExIox). Animals—20 client-owned, healthy adult and geriatric cats. Procedures—Plasma clearance of TIox was determined via multisample and slope-intercept

Andrahandsanalys när estimerat GFR (eGFR) beräknad från kreatinin, clearance and the 2-sample clearance (5, 120) yielded a regression equation not significantly different from the line of identity (Fig 1) with coefficient of determination R2 5 .9009. Concordance coefficient was .930 (Pearson 5 .949, accuracy coefficient 5 .980). In cats, 10-point iohexol plasma clearance ranged from 6.10 to 72.85 mL min21 m22. Iohexol: studies comparing iohexol with inulin clearance To the best of our knowledge, only two studies have compared urinary clearances of iohexol and inulin [ 100 , 101 ] (Table 2 ).

NCI Thesaurus (NCIt) Iohexol is a benzenedicarboxamide compound having N-(2,3-dihydroxypropyl)carbamoyl groups at the 1- and 3-positions, iodo substituents at the 2-, 4- and 6-positions and an N-(2,3-dihydroxypropyl)acetamido group at the 5-position.

(GFR) during pregnancy have been overcome by the introduction of iohexol (Omnipaque ®) clearance [2, 3]. 23 Aug 2016 For plasma iohexol clearance studies, the mean GFR measured by inulin was 66 ± 40 mL/min/1.73 m2. Median bias for iohexol was +3% (95% CI The clearance equation is: Clearance The iohexol is measured and the GFR is calculated [16]. In 1999, the MDRD equation for eGFR was published.

För att lättare förstå begreppet renal clearance kan man ta ett exempel med kreatininclearance. Doseringen av läkemedel som främst utsöndras via njurarna (renal elimination) bör vid nedsatt njurfunktion anpassas så att läkemedelskoncentrationen inte blir för hög och allvarliga biverkningar drabbar patienten. Detta är särskilt viktigt hos äldre, eftersom njurfunktionen påtagligt minskar med stigande ålder.

Comparison of iohexol plasma clearance formulas vs. inulin urinary clearance for measuring glomerular filtration rate October 2020 Clinical Chemistry and Laboratory Medicine -1(ahead-of-print)

Iohexol: studies comparing iohexol with inulin clearance To the best of our knowledge, only two studies have compared urinary clearances of iohexol and inulin [ 100 , 101 ] (Table 2 ). Both showed excellent correlation between the two methods, but the statistical tools used in the original publications were limited and re-analysed data demonstrated less impressive concordance [ 3 ]. Serum iohexol concentration for each serum sample was measured using deltaDOT Ltd.'s previously validated high‐performance capillary electrophoresis method. 24 Glomerular filtration rate was estimated from the iohexol clearance data by application of a compartmental model and a dog‐specific correction formula, 13 normalized to body weight in kilograms.
