Comparative Survival Analysis of Dialysis and Renal Transplantation in HBV-Infected End-Stage Renal Disease Patients.

BACKGROUND: The potential risks and benefits of kidney transplantation in patients with end-stage renal disease (ESRD) infected with hepatitis B virus (HBV) have been a subject of debate. This study aimed to provide real-world data on the relative risks of death and clinical outcomes associated with kidney transplantation in this context. METHODS: We conducted a longitudinal cohort study using the National Health Insurance Research Database from 1997 to 2013, extracting cohorts of patients who are HBV-infected ESRD. The main outcome measure was overall survival, whereas the secondary measure was the relative risk of death and survival benefit through propensity-score matching (1:1). RESULTS: Of the 4895 patients who are HBV-infected with ESRD, 172 renal transplant recipients were enrolled for analysis. There was a numeric trend towards higher overall survival rates in renal transplant recipients, although this was not statistically significant (P = .057). A significant survival benefit was observed in the renal transplant group if the follow-up was longer than one year (P = 0.007). The relative risks of death among renal transplant recipients were initially higher at 2.0 times that of patients on chronic dialysis, presenting in a hyperbolic pattern with equal risks at 462 days. The likelihood of survival became equal until 1649 days. CONCLUSIONS: Our study suggests that kidney transplantation may be a viable option for patients who are HBV-infected with ESRD, given the significant improvement in quality of life and reduction of death risks observed four to five years after successful transplantation. This real-world data can help clinicians make informed decisions regarding the management of ESRD in patients who are HBV-infected.
