Summary

Continuing hydroxychloroquine (HCQ) during pregnancy is recommended for women with systemic lupus erythematosus (SLE). Discontinuing HCQ increases lupus activity without affecting fetal outcomes.

Area of Science:

  • Obstetrics and Gynecology
  • Rheumatology
  • Pharmacology

Background:

  • Systemic lupus erythematosus (SLE) management during pregnancy often requires hydroxychloroquine (HCQ).
  • Understanding HCQ's impact on maternal and fetal health in SLE pregnancies is crucial.

Purpose of the Study:

  • To evaluate lupus activity and pregnancy outcomes in women with SLE based on HCQ treatment during pregnancy.
  • To compare outcomes between women who continued HCQ, ceased HCQ, or had no HCQ exposure.

Main Methods:

  • Prospective study of 1987-2002 pregnancies in women with SLE.
  • Categorized pregnancies into: no HCQ (163), continuous HCQ (56), and HCQ cessation (38).
  • Compared pregnancy/fetal outcomes and lupus activity across groups.

Main Results:

  • No significant differences in miscarriage, stillbirth, or congenital abnormalities among groups.
  • Significantly higher lupus activity and flare rates in women who stopped HCQ.
  • Women continuing HCQ required lower average prednisone doses.

Conclusions:

  • Continuation of HCQ during pregnancy is recommended for SLE patients.
  • Findings support the safety of HCQ, with no observed fetal toxicity.
  • Cessation of HCQ increases maternal lupus activity, similar to nonpregnant individuals.
