Abstract

Background Chronic kidney disease (CKD) is a frequent long-term complication after liver transplantation (LT) and is associated with poor long-term survival. The aim of our study was to identify the risk factors of developing post-transplant CKD at 1 year, during the pre-operative, peri-operative, and post-LT phases. Methods All consecutive patients who underwent primary LT between July 2013 and February 2018 were analyzed. To assess the impact of peri- and post-operative factors on renal function at 1 year we performed a propensity score matching on gender, age of the recipient, Model for End-Stage Liver Disease (MELD) score, etiology of the hepatic disease, and estimated Glomerular Filtration Rate (eGFR) at baseline. Results Among the 245 patients who underwent LT, 215 had available data at one year (Y1), and 46% of them had CKD. Eighty-three patients in the CKD group and 83 in the normal renal function group were then matched. The median follow-up was 35 months (27-77). Patients with CKD at Y1 had a decreased 5-year survival compared to patients with normal renal function at one year: figures were 62% and 90%, respectively, p = 0.001. The independent predictors of CKD at Y1 were major complications (OR = 2.2, 95% CI [1.2-4.2]), p = 0.015, intensive care unit (ICU) stay > 5 days (OR = 2.2, 95% CI [1.3-5.1]), p = 0.046, ICU serum lactate level at 24 h >= 2.5 mmol/L (OR = 3.8 95% CI [1.1-8]), p = 0.034, need for post-LT renal replacement therapy (OR = 6.4 95% CI [1.4-25]), and MELD score >= 20 (OR = 2.1 95% CI [1.1-3.9]), p = 0.019. Conclusions The peri-operative period has a major impact on CKD incidence. Early recognition of patients at high risk of CKD may be critical for implementation of nephroprotective measures.
