ABSTRACT
The outcome of patients with cirrhosis and chronic kidney disease treated with combined liver-kidney transplantation (CLKT) is not well known because most series of patients treated with CLKT include not only patients with cirrhosis but also patients with inherited diseases without cirrhosis. To evaluate to what extent the combined kidney transplantation impairs posttransplantation outcome compared to liver transplantation (LT) alone, the outcome of patients with cirrhosis and chronic kidney disease treated with CLKT (n = 20) was compared to that of a group of patients with cirrhosis without chronic kidney disease treated with LT alone matched by age, sex, year of transplantation and severity of cirrhosis (n = 60). The primary end point of the study was survival, and secondary end points were outcome of renal function and complications within 6 months of transplantation. Patients with CLKT had a higher incidence of bacterial infections and transfusion requirements compared to LT patients. The incidence of acute renal failure during the first 6 months was similar, yet the severity of renal failure was greater in patients with CLKT. Hospital and intensive care unit (ICU) stays were longer in the CLKT group. One- and three-year survival probabilities in patients treated with CLKT were 80 and 75% compared to 97 and 88%, respectively, in patients treated with LT. In conclusion, CLKT for patients with cirrhosis and chronic kidney disease is associated with a relatively high frequency of postoperative complications that moderately impairs short-term survival. However, 3-year survival of patients with cirrhosis treated with CLKT is excellent.
