Long-term Survival and Evolution of the Kidney Function for Liver Transplant Patients Who Required Postoperative Dialysis

Abstract Patients who underwent orthotopic liver transplantation (OLT) frequently develop chronic kidney disease, with those who present postoperative acute kidney failure and require renal replacement therapy (RRT) at higher risk. The objective of the study was to assess the kidney function and long-term survival of patients who underwent OLT and required RRT during or in the immediate postoperative period. Medical records of OLT and postoperative RRT patients with over 6-month survival were reviewed between January 1, 2005, and December 31, 2015. A variance analysis was carried out for repeated measurements to compare the estimate glomerular filtration rate (eGFR) baseline with the different periods (statistical significance level P 2 , respectively. The comparison of the eGFR baseline within the different periods was statistically significant at 1 year and at 3 years. Four patients died, 3 of them due to sepsis and 1 due to recurrence of hepatitis C virus infection. The average survival was 28 months. The probability of surviving at 1 year was 100%, at 3 years was 84.21% (95% confidence interval: 58.65–94.62), and at 5 and 10 years was 78.6% (95% confidence interval: 52.49–91.39). In conclusion, we have found a progressive worsening of the kidney function in the long term in patients who required postoperative dialysis. However, actuarial survival of these patients was very successful.
