Data from: Kinetic estimation of GFR improves prediction of dialysis and recovery after kidney transplantation

Background: The early prediction of delayed graft function (DGF) would
facilitate patient management after kidney transplantation. Methods: In a
single-centre retrospective analysis, we investigated kinetic estimated
GFR under non-steady-state conditions, KeGFR, in prediction of DGF.
KeGFRsCr was calculated at 4h, 8h and 12h in 56 recipients of deceased
donor kidneys from initial serum creatinine (sCr) concentrations,
estimated creatinine production rate, volume of distribution, and the
difference between consecutive sCr values. The utility of KeGFRsCr for DGF
prediction was compared with, sCr, plasma cystatin C (pCysC), and
KeGFRpCysC similarly derived from pCysC concentrations. Results: At 4h,
the KeGFRsCr area under the receiver operator characteristic curve (AUC)
for DGF prediction was 0.69 (95% CI: 0.56–0.83), while sCr was not useful
(AUC 0.56, (CI: 0.41–0.72). Integrated discrimination improvement analysis
showed that the KeGFRsCr improved a validated clinical prediction model at
4h, 8h, and 12h, increasing the AUC from 0.68 (0.52–0.83) to 0.88
(0.78–0.99) at 12h (p = 0.01). KeGFRpCysC also improved DGF prediction. In
contrast, sCr provided no improvement at any time point. Conclusions:
Calculation of KeGFR from sCr facilitates early prediction of DGF within 4
hours of renal transplantation.
