摘要

Objectives

The primary objective of this prospective cohort study was to assess the usefulness of a predefined multidisciplinary care pathway-based management on pregnancy outcome(s) in women with SLE who already had at least one adverse obstetric outcome(s).

Methods

Between March 2010 and March 2023, all consecutive, consenting women with SLE who already had at least one previous adverse obstetric outcome (preterm labour, pre-eclampsia, termination of pregnancy, miscarriage, intrauterine growth retardation (IUGR), preterm birth, low birth weight (LBW), intrauterine death (IUD) or stillbirth] were prospectively screened and counselled. The protocol comprised preconception and post-natal drug and disease status review, periodic ante-natal visits for the monitoring of pregnancy and drug and disease status review and post-natal drug and disease status review and contraception advice. Therapeutic changes were made as necessary at each visit.

Results

A total of 213 women were screened and 197 women (age, 28 ± 6.34 years) were enrolled who had 226 pregnancies. Previous poor obstetric outcomes were miscarriage(s), 186; termination of pregnancy, 4; preterm labour, 51; IUGR, 36; IUD or stillbirth, 16; low birth weight (LBW), 44 and pre-eclampsia, 4. Seventy-seven (39%) women had secondary APS and 37 (19%) had a history of lupus nephritis. There were 194/226 (86%) live births [40 LBW (18%); caesarean section in 101 (45%)]. Thirty pregnancies culminated in miscarriages and 2 in IUDs (14%). Sixty-eight patients (30%) experienced lupus flare during pregnancy (36 mild, 20 moderate and 8 severe).

Conclusion

Our experience underscores the usefulness of a predefined multidisciplinary care pathway-based management for improving pregnancy outcomes in women with SLE who had previous adverse outcomes.

Key Points

• In women with SLE who had previous adverse obstetric outcome(s) a risk of poor outcome in subsequent pregnancy remains.

• Good pregnancy outcomes in these women could be achieved by predefined multidisciplinary care pathways focussed on addressing all relevant issues.

• Improved access to rheumatology services and collaboration between rheumatologists and obstetricians is key to improving outcomes in SLE pregnancies.
