title: Comparison of results of combined liver-kidney transplantation vs. isolated liver transplantation.
abstract: BACKGROUND
  Combined liver-kidney transplantation (LKT) is the best therapeutic option for patients with end-stage liver and kidney disease.
  
  
  OBJECTIVE
  To analyze baseline characteristics and clinical outcome of LKT compared to isolated liver transplantation (LT).
  
  
  METHODS
  The study included 16 LKT performed between 1998 and 2006 and 32 LT matched by age, sex, date and indication for transplantation. Demographic, pretransplant, post-transplant and survival variables were analyzed.
  
  
  RESULTS
  As planned by the study design, mean age, distribution by sex and indication for LT were similar between groups. The most common indication for LT was HCV- and/or alcohol-induced cirrhosis. The most common indication for KT was renal failure, in most cases secondary to glomerulonephritis. Twelve patients (69%) were on dialysis before LKT. Hepatocellular carcinoma and diabetes mellitus pre-transplantation were similar between groups. However pretransplant arterial hypertension (AHT) was higher in LKT than LT (50% vs. 19%; p = 0.02). In the post-transplant: reoperation due to bleeding, bacterial infections, liver rejection, AHT and median creatinine levels at 1st and 3rd years were similar in LKT and LT. In contrast, early post-transplant dialysis was higher in LKT than LT (31% vs. 3%; p = 0.01). Survival rates at 1st, 3rd, 5th and 7th years were similar in both groups (87.5%, 74%, 74% and 66% vs. 81%, 75%, 75% and 75% in LT and LKT, respectively).
  
  
  CONCLUSIONS
  LKT is an effective therapeutic option in patients with end-stage liver and kidney disease. Most early and late complications and long-term survival are similar to those observed with LT.
