Abstract

Background

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory condition with multi-organ involvement predominantly affecting young women. There are very limited studies in pregnancy in Asian SLE patients and therefore we embarked on this study to identify pregnancy outcomes of Malaysian women with SLE.

Materials and methods

We performed a retrospective study of pregnancy outcomes in SLE patients in our institution from January 2007 to December 2014. A total of 71 pregnancies from 44 women were analysed.

Results

The mean age of our cohort was 30.5 ± 3.9 years. The rate of active disease at conception, antiphospholipid syndrome and lupus nephritis were 22.5%, 32.4% and 57.7% respectively. SLE flare occurred in 33 out of 71 pregnancies whereas 19 pregnancies were complicated with preeclampsia. The livebirth rate for our cohort was 78.9%, whilst preterm delivery was 42.9%. On univariate analysis, active disease and flare in pregnancy were both strongly associated with foetal loss and preterm delivery. Lupus nephritis (p = 0.011), SLE flare (p = 0.008) and antiphospholipid syndrome (p = 0.032) significantly increased the risk of preeclampsia. Aspirin and hydroxychloroquine were protective against foetal loss [odds ratio (OR) 0.12] and preeclampsia (OR 0.25), respectively. On multivariate analysis, active disease was a predictor of SLE flare (p = 0.002) and foetal loss (p = 0.018) and SLE flare was the main predictor of preterm delivery (p = 0.006).

Conclusions

Pregnancies in women with SLE should be planned and aspirin and HCQ use were beneficial in reducing adverse pregnancy outcomes.
