- Risk of adverse pregnancy outcomes in pregnant women with SLE [ Time Frame: Up until 28 days after end of pregnancy ]Fetal death, neonatal death, preterm delivery or termination of pregnancy, and small for gestational age neonate confirmed by chart review and autopsy report.
- Change in patterns of ASA use in the LEGACY cohort from baseline ( <or equal to 12 weeks gestation) to end of pregnancy [ Time Frame: From ≤ 12 weeks gestation (baseline) to 8-12 weeks after delivery (postpartum) ]The Adherence to Refills and Medications Scale (ARMS), a validated self-reported questionnaire developed for patients with chronic disease with low literacy, measures ASA adherence. A self-reported aspirin adherence questionnaire consisting of 3 to 6 questions about the use of aspirin during current pregnancy measures ASA use. A visual analogue scale from 0 to 10 measures frequency of ASA ingestion. Change in ASA use will be measured by the questionnaires. Frequencies of dosage of ASA will also be measured.
- Baseline predictors of adverse pregnancy outcomes [ Time Frame: First trimester (up to 20 weeks) ]
Baseline covariates such as lupus anticoagulant antibodies, a subtype of anticoagulant antibodies, Antiphosphatidylserine/prothrombin antibodies (aPS/PT), antihypertensive use, disease activity, platelet levels will be measured and defined by the physician-in-charge. Nephritis history, race/ethnicity, nulliparity, maternal age, pre-gestational diabetes, obsesity (BMI above 30) and medication use (corticosteroids, antimalarials, immunosuppressive and low-dose aspirin) will be characterized.
Measures for disease activity include the SLE Pregnancy Disease Activity Index (SLEPDAI), a widely-recognized adaptation of the validated SLE Disease Activity Index, reflects disease activity in pregnancy context.
- Comparison of Antiphosphatidylserine/prothrombin antibodies (aPS/PT) in SLE pregnancies from ≤ 12 weeks pregnant (baseline) to 8-12 weeks after delivery (postpartum) [ Time Frame: From ≤ 12 weeks gestation (baseline) to 8-12 weeks after delivery (postpartum) ]Positive results for Antiphosphatidylserine/prothrombin antibodies (aPS/PT) and and lupus anticoagulant results in pregnant women with SLE with and without adverse pregnancy outcomes
