Abstract
Objective: To determine the impact of infant recipient body weight at primary liver transplantation (LT) on both recipient and graft survival rates in complete national data from Poland.
Methods: We conducted a single-center, retrospective cohort study including 142 LT recipients below 1 year of age with body weights below 10 kg who received primary and isolated LT between 2001 and 2017. Patients were divided into two study groups according to body weight at the time of LT: (1) Group I (≤6.0 kg, 32 patients) and (2) Group II (6.1-9.9 kg, 110 patients). Independent impact of body weight on patient and graft survival were assessed using survival curves and a multivariable Cox regression analysis. The univariate predictors of mortality or retransplantation at 1 year post-LT were recipient body weight of ≤6 kg at transplantation, pediatric end-stage liver disease score, urgent LT, graft from deceased donor, cold ischemia time, post-LT hepatic artery thrombosis, and post-LT dialysis.
Results: No statistically significant impact of body weight ≤6 kg on 1-year failure-free survival was found based on the multivariable analysis (p = 0.063). Body weight ≤6 kg was associated with longer post-LT intensive care unit and post-LT hospital stays (p = 0.013 and 0.025, respectively).
Conclusions: Since no evidence of independent negative impact of recipient body weight ≤6 kg on failure-free survival 1 year post-LT was found, LT in infants with end-stage liver disease in Poland should be performed according to medical indications and urgency when an appropriate donor is available.
