Pregnancy in women with systemic lupus erythematosus (SLE) carries risks. While lupus flares during pregnancy don't affect outcomes, specific factors predict pregnancy loss and preterm birth, aiding risk assessment.

Area of Science:

  • Rheumatology
  • Obstetrics
  • Immunology

Background:

  • Systemic lupus erythematosus (SLE) is an autoimmune disease impacting multiple organs.
  • The course and risks of pregnancy in SLE patients require further elucidation.
  • Existing data on lupus pregnancy outcomes are limited.

Purpose of the Study:

  • To prospectively evaluate the course of pregnancy in patients with SLE.
  • To identify risk factors for lupus flares during pregnancy.
  • To determine predictors of adverse pregnancy outcomes in SLE.

Main Methods:

  • Prospective follow-up of 64 patients (74 pregnancies) with SLE since 1987.
  • Monthly clinical assessments and collection of pregnancy-related data.
  • Emphasis on monitoring lupus flare occurrence and specific biomarkers.

Main Results:

  • The flare rate during pregnancy (1.63/person-year) was significantly higher than postpartum or in non-pregnant individuals.
  • Lupus flares during pregnancy did not correlate with adverse pregnancy outcomes.
  • Low C3/C4 and high anticardiolipin antibodies predicted pregnancy loss.
  • Prednisone dose, aspirin use, second-trimester diastolic blood pressure, initial C3 levels, and race predicted preterm birth.

Conclusions:

  • Maternal lupus flares and preterm birth represent significant risks in SLE pregnancies.
  • Predictive markers for pregnancy loss and preterm birth in SLE pregnancies have been identified.
  • Early identification of at-risk pregnancies allows for targeted monitoring and management.
