Brief summary

The purpose of the study is to evaluate the ability of placental angiogenesis markers to predict the risk of PE in pregnancy in women with primary APS. To construct reference intervals of placental angiogenesis markers specific to women affected by primary APS in pregnancy by measuring the levels of sFlt-1and PlGF in serum maternal serum and their sFlt-1/PlGF ratio during the trimesters of gestation (I TM, II TM and III TM). For this aim the study will involve recruiting two groups of subjects, one will be cases and one will be controls.

Interventions

OTHERCollection of epidemiological and anamnestic data and collection of biological material (peripheral blood)

Patients will be enrolled in the study during the first trimester of gestation or later, if the diagnosis of APS is made during pregnancy followed by clinical practice. During the quarterly visits scheduled by clinical practice, the following will be collected relevant clinical information and the additional biological samples for analysis of serum levels of sFlt-1 and PlGF. A follow-up postpartum visit is scheduled by clinical practice at 6 weeks after completion of delivery.
