Combined liver and kidney transplantation (CLKT) has been proposed as effective treatment for patients with chronic diseases of both organs, some with hepatorenal syndrome and for liver-based metabolic diseases affecting kidney. This study is undertaken to analyze results of CLKT at a single center. Of 2690 LTs performed between 1992 and 2007, there were 39 CLKTs; most common indications were metabolic, cirrhosis and polycystic disease. With follow-up of up to 170 months, 11 died (overall survival 71.8%); one-, five-, and 10-yr patient and liver graft survival is 77%, 73.7%, and 73.7%, respectively, and kidney graft survival is 77%, 70%, and 70%, respectively. Survival among metabolic group (78.6%) appeared to be better than non-metabolic group (68%); however, this difference was not significant (p = 0.39). Fifteen surviving patients (53.6%) have mild/moderate renal impairment (creatinine ≥125 μmol/L). None has severe renal failure (serum creatinine ≥250 μmol/L) or end-stage renal disease requiring hemodialysis. CLKT has good results in selected groups of patients. It provides protection to kidney allograft in liver-based metabolic diseases affecting kidney. The rate of acute rejection episodes of kidney is low. Significant proportion develops long-term mild/moderate renal dysfunction. Careful attention to immunosuppression to minimize nephrotoxicity may help.
