Pregnant patients with systemic lupus erythematosus (SLE) represent a high-risk group. The aim of this study is to describe the pregnancy outcomes among SLE patients who were followed prospectively at a conjoint high-risk pregnancy/rheumatology clinic from 2007 to 2021 and to identify predictors of adverse maternal and fetal outcomes. This study included 201 singleton pregnancies of 123 women with SLE. Their mean age was 27.16 ± 4.80 years, and their mean disease duration was 7.35 ± 5.46 years. Secondary antiphospholipid syndrome (APS) was diagnosed in 77 (38.3%) pregnancies. The pregnancy was planned in 104 (51.7%) pregnancies. Flares occurred in 83 (41.3%) and pre-eclampsia in 15 (7.5%) pregnancies. Full-term pregnancy occurred in 93 (46.3%), fetal loss (miscarriage and intra-uterine fetal death) in 41 (20.4%), and prematurity in 67 (33.3%) of the pregnancies, respectively. Seven neonates died from complications of prematurity, and another one died from cardiac congenital anomalies. In the multivariate analyses, unplanned pregnancy was associated with eight times higher risk of disease flare OR = 7.92 (p < 0.001), lupus nephritis flare during pregnancy increased the odds of pre-eclampsia occurrence four times OR = 3.98 (p = 0.02), while disease flares during pregnancy predicted prematurity OR = 2.49, p = 0.049. Patients with secondary APS had three times increased risk of fetal loss OR = 2.97, p = 0.049. To conclude, unplanned pregnancy, disease flares, and APS have been identified as predictors for adverse maternal and/or fetal outcomes. Pregnancy planning is necessary to reduce maternal and fetal complications.
