Long-Term Outcomes of Simultaneous Liver-Kidney Transplant Patients with Hepatitis B Compared to with Liver Transplant Alone.

ABSTRACT

BACKGROUND: The number and survival rate of simultaneous liver-kidney transplant (SLKT) recipients have increased dramatically since 2002. However, the long-term effectiveness of SLKT in patients with hepatitis B is unknown. MATERIAL/METHODS: Forty-six patients who visited the Organ Transplant Center of the Shanghai First People's Hospital between January 2001 and May 2005 had hepatitis B virus infection and renal failure (any degree), and underwent organ transplantation 21 patients underwent SLKT and 25 patients underwent liver transplant (LT) alone. RESULTS: The 1-, 3-, and 5-year survival rates of SLKT recipients were 90.5%, 81.0%, and 81.0%, respectively. Incidence of acute hepatic allograft rejection between SLKT recipients and LT recipients (33% vs. 16%) did not reach significance (P=0.170). Despite higher infection rate, more prevalent hepatitis B relapse, and longer stay in the intensive care unit, SLKT recipients experienced significantly higher 1-year survival rate (90.5%) compared with LT recipients (60%, P=0.019). Multivariate regression analysis revealed that postoperative renal failure (odds ratio (OR)=48, P=0.003) and Risk/Injury/Failure/Loss/End-stage (RIFLE) stage (OR=8, P=0.012) were independent risk factors for postoperative death after LT. CONCLUSIONS: SLKT in patients with hepatitis B had higher early-stage infection rate, but had a higher long-term survival rate compared with the LT group. Although the incidence of postoperative hepatitis B relapse in SLKT recipients was higher, timely and reasonable treatment can ensure long-term survival of patients. Worsening RIFLE stage of recipients can predict high mortality when only given LT. SLKT might be a better choice for RIFLE stage 2 or 3 patients than LT alone.
