Abstract

BACKGROUND:

The indications for simultaneous and sequential pediatric liver (LTx) and kidney (KTx) transplantation have not been well defined. We herein report the results of our experience with these procedures in children with end-stage liver disease and/or subsequent end-stage renal disease.

PATIENTS AND METHODS:

Between 1984 and 1995, 12 LTx recipients received 15 kidney allografts. Eight simultaneous and seven sequential LTx/KTx were performed. There were six males and six females, with a mean age of 10.9 years (1.5-23.7). One of the eight simultaneous LTx/KTx was part of a multivisceral allograft. Five KTx were performed at varied intervals after successful LTx, one KTx was performed after a previous simultaneous LTx/KTx, and one KTx was performed after previous sequential LTx/KTx. Immunosuppression was with tacrolimus or cyclosporine and steroids. Indications for LTx were oxalosis (four), congenital hepatic fibrosis (two), cystinosis (one), polycystic liver disease (one), A-1-A deficiency (one), Total Parenteral Nutrition (TPN)-related (one), cryptogenic cirrhosis (one), and hepatoblastoma (one). Indications for KTx were oxalosis (four), drug-induced (four), polycystic kidney disease (three), cystinosis (one), and glomerulonephritis (1).

RESULTS:

With a mean follow-up of 58 months (0.9-130), the overall patient survival rate was 58% (7/12). One-year and 5-year actuarial patient survival rates were 66% and 58%, respectively. Patient survival rates at 1 year after KTx according to United Network of Organ Sharing (liver) status were 100% for status 3, 50% for status 2, and 0% for status 1. The overall renal allograft survival rate was 47%. Actuarial renal allograft survival rates were 53% at 1 and 5 years. The overall hepatic allograft survival rate was equivalent to the overall patient survival rate (58%). Six of seven surviving patients have normal renal allograft function, and one patient has moderate chronic allograft nephropathy. All surviving patients have normal hepatic allograft function. Six (86%) of seven sequentially transplanted kidneys developed acute cellular rejection compared with only two (25%) of eight simultaneously transplanted kidneys (P<0.04).

CONCLUSIONS:

Simultaneously transplanted kidneys were less likely to develop rejection than sequentially transplanted kidneys in this series. This did not have any bearing on patient or graft survival rates. Mortality correlated directly with the severity of United Network of Organ Sharing status at the time of kidney transplantation. Candidates for simultaneous or sequential LTx/KTx should be prioritized based on medical stability to optimize distribution of scarce renal allografts.
