This study looked at pregnancy outcome among Lupus patients over a 2-decade period (1990-2010), compared to otherwise healthy individuals. The numbers don’t look good:
1) 26% of lupus pregnancies did not result in livebirths, with the presence of the Antiphospholipid antibodies being associated with a 3-fold increase risk of miscarriage;
2) complication rates were 50% among mothers, 33% among foetuses;
3) SLE flared in 46%, with pre-eclampsia in 8% and HELLP in 5%;
4) intrauterine growth restriction, premature delivery and Caesarean rates were significantly higher among Lupus patients.


In largest study to date, 81% of pregnant women with lupus had no complications.

In this more recent and much larger study (largest-to-date) looking solely at Lupus patients (PROMISSE), the pregnancy outcome numbers are far better. Maternal complication rate was below 20%.
This may be attributable to better management of SLE: ensuring disease remission (preferably) before embarking on pregnancy, and very close follow-up during pregnancy.
Risk factors for poorer outcomes have been identified. Read on.

This is a good checklist for Lupus patients before, during and after pregnancy: the “do’s” and “don’t’s”; including what drugs to avoid, and, more importantly, what drugs to continue. The worst thing one can do is to enter into pregnancy with active disease, or to risk disease flaring during pregnancy, because vital medicines were stopped due to misinformation or misconceived notions like wanting to go “au naturale”.
