Abstract:
Purpose:The incidence of chronic kidney disease (CKD) has been increasing due to improved survival after liver transplantation (LT). Risk factors of kidney injury after LT, especially perioperative management factors, are potentially modifiable. We investigated the risk factors associated with progressive CKD for 10 years after LT.
Methods:This retrospective cohort study included 292 adult patients who underwent LT at a tertiary referral hospital between 2000 and 2008. Renal function was assessed by the e stimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease formula. The area under the curve of serial eGFR (AUCeGFR) was calculated for each patient to assess the trajectory of eGFR over the 10 years. Low AUCeGFR was considered progressive CKD. Linear regression analyses were performed to examine the associations between the variables and AUCeGFR.
Results:Multivariable analysis showed that older age (regression coefficient = -0.53, P < 0.001), diabetes mellitus (DM) (regression coefficient = -6.93, P = 0.007), preoperative proteinuria (regression coefficient = -16.11, P < 0.001), preoperative acute kidney injury (AKI) (regression coefficient = -14.35, P < 0.001), postoperative AKI (regression coefficient = -3.86, P = 0.007), and postoperative mean vasopressor score (regression coefficient = -0.45, P = 0.034) were independently associated with progressive CKD.
Conclusion:More careful renoprotective management is required in elderly LT patients with DM or preexisting proteinuria. Postoperative AKI and vasopressor dose may be potentially modifiable risk factors for progressive CKD.
