Feto-maternal outcomes of pregnancies in women with SLE: Experience from a tertiary care center of Asia

Objective We aim to quantify the risk of maternal and fetal complications in patients with SLE in order to identify the impact of SLE on pregnancy and of pregnancy on SLE. Methods This retrospective record review study was conducted in Aga khan university hospital, Karachi, from Jan 1998 to Dec 2019. All pregnant patients with SLE diagnosed and delivered during this time were included in the study. Categorical variables were analyzed by using chi-square test and fisher exact test. Whereas quantitative point estimate was estimated as mean and SD. We matched the data and computed crude odds ratio of pre-eclamptic patients with respect to age of conception, gravida, and body mass index in both case and control group. Results The SLE disease activity was monitored during pregnancy under SLEDAI-2K Scoring system. The patients with mild (25.6%) and moderate (25.6%) disease activity were prevalent and most antenatal patients (51.7%) had flare up in third trimester. Adverse maternal outcomes include pre-eclampsia (28.8%), eclampsia (3.2%), cesarean section (57.6%), and thrombocytopenia (9.6%), whereas perinatal outcomes includes intrauterine growth retardation (24%), preterm birth <34 weeks (19.2%) and <37 weeks (63.2%), APGAR Score < 7 at 1 min (5.6%), and neonatal death (5.6%) found to be statistically significant in between two groups There were more high-risk patients (42) with positive IgG (88%), IgM (83.3%), and lupus anticoagulant (33.3%) as compared to low-risk APS group. Conclusion Planned pregnancy and less severe disease flares during pregnancy is associated with more favorable feto-maternal outcomes.
