Abstract：
The current treatment to prevent pregnancy morbidity (PM) associated with antiphospholipid antibodies (aPL) is based on the use of low dose aspirin and low molecular weight heparin (henceforth defined as standard of care (SoC) treatment). Despite the SoC, up to 30% of women with aPL continue to have pregnancy complications. The global antiphospholipid syndrome (APS) score (GAPSS) is a tool to quantify the risk for the aPL-related clinical manifestations. In this study, we investigated the individual clinical response to SoC in women with aPL after stratifying them according to their GAPSS.
One-hundred-fourty-three women (352 pregnancies) with aPL ever pregnant treated with SoC therapy were included. The patients GAPSS was then grouped according to the patients\' GAPSS into low risk (< 6), medium risk (6-11), and high risk (≥12).
The live birth rate was 70.5% (248 out of the 352 pregnancies), 45 patients (31%) experienced at least one event of PM, defined as early or late. Patients were stratified according to GAPSS values, in order to identify a low risk group (GAPSS <6, n = 72), a medium risk group (GAPSS 6-11, n = 66) and a high risk group (GAPSS ≥12, n = 5). When considering patients who ever experienced any PM while treated with SoC, all patients in the high risk group experienced PM, while patients in the medium group had a significant higher rate of PM when compared to the low risk group [29 (43.9%) patients V.s. 11 (15.3%), respectively; p < 0.001]. When analysing the number of pregnancies in the three groups, patients in the high risk group had significantly lower live birth rates, when compared to the other groups [11 (40.7%) live births vs. 100 (62.1%) and 137 (82.5%), respectively; p < 0.05]. Furthermore, patients with medium risk group also had significantly lower live birth rates, when compared to the lower risk group (p < 0.001).
GAPSS might be a valuable tool for to identify patients with a higher likelihood of response to SoC.
