Lupus nephritis (LN) predominately affects females of childbearing age. This study aims to characterize pregnancy outcomes in kidney transplant recipients (KT) with LN compared to other glomerulonephritis (other-GN) and non-glomerular diseases (non-GN). We analyzed 1022 KT with 1867 pregnancies and 1932 outcomes reported to Transplant Pregnancy Registry International.

Conclusions: The majority of pregnancies in KT with LN resulted in live births with high rate of preeclampsia and prematurity. Overall, post-transplant pregnancies in LN are successful and the outcomes are similar to KT with other ESRD etiologies.
