| Summary: | OBJECTIVE: To investigate risk factors for the development of chronic kidney disease and death two years postliver transplantation. METHOD: Associations between clinical and laboratory parameters and the development of chronic kidney disease and survival two years post-liver transplant were analyzed in a cohort of 148 adult patients with hepatic cirrhosis consecutively submitted to liver transplantation in a referral Brazilian center. RESULTS: Median age at liver transplantation was 56 (range, 20-73) years, and 105 (70.9%) patients were males. The prevalence of chronic kidney disease at two years post-liver transplantation was: stage 1 or no chronic kidney disease, 27.5%; stage 2, 33.8%; stage 3, 34.6%; stages 4-5, 4.7%. Four variables were independently associated with the stage of chronic kidney disease two years after liver transplantation: (i) age (at liver transplantation), (ii) male gender, (iii) median tacrolimus levels in the first three months post-liver transplantation, and (iv) median of serum creatinine in the first six months post-liver transplantation. Two variables showed independent association with death in two years post-liver transplantation: (i) stay in Intensive Care Unit for three or more days after the liver transplantation surgery and (ii) median of serum creatinine levels in the first six months post-liver transplantation equal or higher than 1.3 mg/dL. CONCLUSIONS: Administration of the lowest effective dose of tacrolimus and adoption of strategies to spare renal function are important measures to reduce the risk of late chronic kidney disease and death post-liver transplantation especially in high risk patients.
