    Abstract:
    OBJECTIVE: Pregnant women with SLE have higher probabilities of maternal complications. SLE during pregnancy has alternating patterns of remission and flare-ups; however, most pregnant SLE patients tend to worsen with associated poor obstetric and perinatal outcomes. This study aimed to describe obstetric outcomes in pregnant women with SLE. METHODS: This retrospective study was performed between 2011 and 2020 at a highly complex referral health center in Cali, Colombia. Pregnant women with a diagnosis of SLE were included. Demographic, clinical, and laboratory features and obstetric and fetal outcomes, including intensive care unit (ICU) characteristics, were evaluated. RESULTS: Forty-eight pregnant women with SLE were included. The median age was 29 (25-33.7) years. The SLE diagnosis was made before pregnancy in 38 (79.1%) patients, with a median disease duration of 46 (12-84) months. Thirteen (27.1%) patients had lupus nephritis. Preterm labor (34, 70.8%), preeclampsia (25, 52%), and preterm rupture of membranes (10, 20.8%) were the most common obstetric complications. A relationship between a greater systemic lupus erythematosus pregnancy disease activity index (SLEPDAI) and the development of hypertensive disorders during pregnancy was established (preeclampsia = p < 0.0366; eclampsia = p < 0.0153). A relationship was identified between lupus nephritis (LN) and eclampsia (p < 0.01), preterm labor (p < 0.045), and placental abruption (p < 0.01). Seventeen (35.4%) patients required ICU admission; 52.9% of them were due to AID activity, 17.6% for cardiovascular damage, 11.7% for septic shock, and 5.8% for acute kidney failure. Fetal survival was 89.5% (N = 43/48). Among the live births, two (4.2%) newborns were diagnosed with neonatal lupus, and two (4.2%) were diagnosed with congenital heart block. One maternal death was registered due to preeclampsia and intraventricular hemorrhage. CONCLUSIONS: This study is the first to describe SLE during pregnancy in Colombia. SLE was the most prevalent AID in this cohort, and complications included preterm labor, preeclampsia, and postpartum hemorrhage. A higher SLEPDAI and lupus nephritis predicted adverse maternal outcomes.
