A Comparison of Obstetric Outcomes in Antiphospholipid Syndrome Among Pregnant Women With Systemic Lupus Erythematosus.

Objective The aim of this study was to evaluate the maternal and perinatal outcomes in systemic lupus erythematosus (SLE) women with antiphospholipid syndrome (APS). Methods This retrospective case-control study was conducted among pregnant women with SLE with and without APS. Group A included SLE patients with APS, whereas group B included pregnant SLE women without APS. Data were expressed as mean ± standard deviation (SD). Frequency and percentage were computed for categorical data. The chi-square test was used to analyze the difference between categorical data. Results Out of 125 cases of SLE, APS was found in 72 (57.6%) women. Almost 95.8% of patients were on treatment (aspirin and enoxaparin) in group A. Preterm delivery (31.89±7.36 versus 34.46±4.97; p=0.021) and termination of pregnancy (18.1% [13/72] versus 5.7% [3/53]; p=0.04) were statistically significant in group A. Among these terminations, second-trimester intrauterine death is found to be more in group A (SLE with APS) (16.7% [12/72]) as compared to group B (SLE without APS) (5.7% [3/53]) with a p-value of 0.05. Perinatal outcomes including NICU admissions (39% [23/59] versus 24% [12/50]; p=0.071) and neonatal death (12.3% [7/57]; p=0.015) were also found to be statistically significant between the two groups. Conclusion APS with SLE is associated with adverse pregnancy outcomes such as preterm birth, termination of pregnancy due to second-trimester fetal loss, more NICU admission, and neonatal deaths when compared to the control group. Hence, pregnancies with APS with SLE require vigilant monitoring and frequent follow-ups to ensure a positive pregnancy outcome.
