Abstract

This study aims to analyze factors related to pregnancy outcomes in women with positive antiphospholipid antibodies and previous adverse pregnancy outcomes (APOs) prospectively. Patients' characteristics were described. Factors associated with obstetric complications were analyzed using logistic regression analysis. A total of 128 females with 73.4% non-criteria obstetric antiphospholipid syndrome (NC-OAPS) were included. APOs accounted for 38.3%, of which 65.3% were fetal losses. Live birth rates in criteria OAPS and NC-OAPS were similar (76.5% and 74.5%). For the whole patients, antinuclear antibody (ANA) titer ≥ 1:160 (OR 5.064, 95% CI (1.509, 16.995), P = 0.009) was a risk factor for APOs and low molecular weight heparin (LMWH) use (OR 0.149, 95% CI (0.029, 0.775), P = 0.024)) was a protective factor. Age (OR 1.159, 95% CI (1.011, 1.329), P = 0.034) and previous APOs ≥ 3 times (OR 3.772, 95% CI (1.14, 12.435), P = 0.029) were risk factors for fetal loss, and LMWH use (OR 0.068, 95% CI (0.009, 0.486), P = 0.007) was a protective factor. Regular rheumatology visits was a protective factor for APOs and fetal loss (OR 0.085, 95% CI (0.024, 0.306), P < 0.001; OR 0.019, 95% CI (0.004, 0.104), P < 0.001). The proportion of it decr...Continue Reading
