Summary

Pregnancy outcomes in lupus nephritis are impacted by proteinuria, hypertension, and antiphospholipid antibodies, which predict fetal loss. Renal quiescence during pregnancy is key for favorable maternal outcomes.

CRITICAL ROLE OF DYSREGULATED AUTOPHAGY IN PATHOPHYSIOLOGY OF PODOCYTOPATHY.

Kidney360·2026

Area of Science:

  • Obstetrics and Gynecology
  • Nephrology
  • Rheumatology

Background:

  • Analyzed 70 pregnancies in 48 women with lupus nephritis.
  • Investigated outcomes for pregnancies developing lupus nephritis during gestation and those with pre-existing lupus nephritis.

Purpose of the Study:

  • To identify predictors of fetal loss and adverse maternal outcomes in pregnancies complicated by lupus nephritis.
  • To assess the impact of disease activity on pregnancy outcomes.

Main Methods:

  • Retrospective analysis of 70 pregnancies in 48 women with lupus nephritis.
  • Categorized pregnancies into those where lupus nephritis developed during pregnancy (Group A) and those with known lupus nephritis (Group B).
  • Multivariate analysis to determine independent predictors of fetal loss and maternal outcomes.

Main Results:

  • Overall fetal loss rate was 36%, with no significant difference between groups.
  • Proteinuria, arterial hypertension, and antiphospholipid antibodies were independent predictors of fetal loss.
  • Renal quiescence at pregnancy onset was the sole predictor of favorable maternal outcome; 3.9% of patients in Group B progressed to irreversible renal failure.

Conclusions:

  • Proteinuria, hypertension, and antiphospholipid antibodies independently predict adverse fetal outcomes in lupus nephritis pregnancies.
  • Maintaining renal quiescence before and during pregnancy is crucial for favorable maternal outcomes.
  • Early identification and management of these risk factors can improve pregnancy outcomes for women with lupus nephritis.
