Relationship of lupus nephritis and pregnancy: A narrative review.

Abstract

Pregnancy in women with lupus, particularly those with lupus nephritis (LN), carries an increased risk of adverse outcomes. Women with active LN at the time of conception are at a high risk of poor maternal and fetal outcomes. Recent studies indicate that even in the presence of quiescent disease, factors such as hypertension and positive lupus anticoagulant are predictors of worse pregnancy outcomes. Consequently, pre-conception evaluation is essential to ensure that pursuing pregnancy is safe and timely, and to facilitate proper planning for optimizing medical regimens, discontinuing teratogenic agents, and treating active disease. Additionally, pre-existing LN is associated with higher rates of preeclampsia and hemolysis, elevated liver enzymes, and low platelet count syndrome. Women with lupus and prior LN can have successful pregnancies, but a multidisciplinary approach with close monitoring is essential for optimal outcomes. By systematically reviewing the available evidence, this narrative review aims to provide a comprehensive update on the complex interaction between LN and pregnancy, offering insights to guide clinical practice and future research in this field.
