The effect of IGL-1 preservation solution on outcome after kidney transplantation: A retrospective single-center analysis

Tijdschriftbijdrage - Tijdschriftartikel

Institut Georges Lopez-1 (IGL-1) solution is increasingly used for kidney preservation, although little information on outcomes is available. Outcomes of all deceased donor kidneys preserved by IGL-1, University of Wisconsin solution (UW), or histidine-tryptophan-ketoglutarate (HTK) and transplanted in our center (2000-2018) were analyzed. Multivariable analysis for delayed graft function (DGF), functional DGF, estimated glomerular filtration rate (eGFR, CKD-EPI equation), proteinuria, acute rejection, death-censored graft loss, and patient survival were performed. A double robust approach, consisting of propensity score weighting and correction for confounders, minimized the risk of bias. In total, 1943 transplants were included: 234 with IGL-1, 1046 with UW, and 663 with HTK. As IGL-1 was only introduced in 2014, a prespecified sensitivity analysis of 917 kidneys (2010-2018) was performed using the same statistical approach. After weighting, IGL-1 retained a higher proportion of kidneys donated after circulatory death (DCD). IGL-1 was not independently associated with any of the outcomes when compared to UW or HTK. Sensitivity analysis between 2010 and 2018 showed similar results. In this retrospective analysis, using robust methodology to reduce the risk of bias, IGL-1 preservation results in equal outcomes compared to UW or HTK, despite more DCD transplants in the IGL-1 group.
