Background: The actual prognostic impact of prior lupus nephritis (LN) diagnosis on end-stage kidney disease (ESKD) patients remains questionable, especially in relation to outcomes of kidney transplantation (KTx) We aim to determine the survival of the graft and recipient after the KTx procedure among patients with ESKD due to LN in comparison to non-LN.
Methods: This meta-analysis included retrospective studies from the last two decades, focusing on the KTx’s outcomes among ESKD due to LN in comparison to non-LN. We establish the graft/recipient survival rate at different follow-up intervals as the primary outcome, and acute graft rejection and pooled graft failure rate as secondary outcomes. All analyses were performed with the random-effect model (REM) and were presented as odd ratio (OR; within 95% confidence interval (CI)). The protocol of this study was registered in PROSPERO: CRD42023394310.
Results: A total of 1,299 KTx (368 LN patients) from 10 studies with >10 years of follow-up were thoroughly reviewed. All checkpoints (at 1-, 5-, 10, and 15-year post-KTx) on graft survival rate demonstrated comparable outcomes in either LN or non-LN (e.g., at 10-year follow up (OR, 1.08 [0.40, 2.91]; p = 0.88). Similar findings at all checkpoints for recipient survival rate were also observed without statistically significant difference between LN and non-LN arm (e.g., at 10-year checkpoint; OR, 0.99 [0.68, 1.46]; p = 0.98). Both of our secondary analyses also presented insignificant differences (p = 0.70 and = 0.16, respectively).
Conclusions: Our findings suggested that prognosis of ESKD due to complicated LN is equal compared to ESKD associated with non-LN etiologies, suggesting the impact of LN as the inducing cause of ESKD on KTx outcome is relatively neglectable.
