Research Article: Placental lesions in patients with antiphospholipid antibody syndrome: experience of a single tertiary-care Italian reference center

Date Published: 2024-09-19

Abstract:
Introduction: Abnormal placentation contributes to obstetric morbidity in antiphospholipid antibodies syndrome (APS). The placenta is the main target of antiphospholipid antibodies (aPL) in obstetric APS and is the site of dysfunctional inflammatory responses and thrombosis. Standard treatment for APS during pregnancy includes low-dose aspirin (LDA) plus low molecular weight heparin (LMWH) and, in refractory cases, hydroxychloroquine (HCQ). Recently, a systematic review of the literature identified five main pathological placental lesions in APS patients: placental infarction, decidual vasculopathy, decidual inflammation, increase of syncytial knots due to syncytiotrophoblast death, and decrease in vasculosyncytial membranes. The aims of this study were to investigate whether placental lesions associate with obstetrical outcomes in a cohort of APS patients.
