BACKGROUND: The impact of renal replacement therapy (RRT) on the long-term survival outcomes of pediatric liver recipients remains controversial.
METHODS: A total of 224 patients aged <18 years, who underwent liver transplantation (LT), were divided into two groups: patients who underwent renal replacement therapy (RRT) (group R, n = 25, 11.2%) and those who did not (group N, n = 199, 88.8%). The posttransplant patient survival outcomes according to RRT use constituted the primary end-point. RRT was initiated preoperatively in 12 patients (48.0%) and postoperatively in 13 [early: <6 months after LT (n = 5, 20.0%) and late: ≥6 months after LT (n = 8, 32.0%)]. The indications for RRT included liver disease involving the kidney (44.0%) and hepatorenal syndrome (56.0%).
RESULTS: The age at the time of LT (71.6 vs. 19.1 months) was higher, the pediatric end-stage liver disease score was lower (9.9 vs. 21.2), and the duration of hospitalization posttransplantation (41.0 vs. 27.0 days) was longer, while the rates of hepatic artery thrombosis (8.0% vs. 3.5%) were higher in group R (p < .05). The number of patients (60.0% vs. 93.0%; p < .001) and graft survival rates (68.0% vs. 93.0%; p < .001) were significantly lower in group R. Multivariate analysis revealed that posttransplant RRT and hepatic artery complications were risk factors for patient survival outcomes. Renal function was recovered in 7 patients (28.0%) in group R, and 9 (36.0%) eventually underwent kidney transplantation.
CONCLUSION: The survival outcomes of children requiring posttransplant RRT were significantly worse than those of children, who did not undergo RRT. Physicians should pay meticulous attention to patients requiring post-LT RRT.
