The association between antiphospholipid antibodies (aPL) and thrombophilic state in antiphospholipid syndrome (APS) is well recognized, but the underlying pathophysiology remains incompletely elucidated. Several findings suggest the role of complement system (CS) in the pathogenesis of antiphospholipid syndrome (APS). The importance of CS in APS is understandable since complement-derived inflammatory mediators increase vascular permeability, activate platelets and promote release of cytokines from monocytesthat favor systemic inflammation and coagulation. It has been demonstrated in a mouse model of aPL-induced pregnancy loss that complement activation can amplify the fetal injury. CS activation has been also documented in patients with APS, but there are far fewer clinical data.

Abstract
The association between antiphospholipid antibodies (aPL) and thrombophilic state in antiphospholipid syndrome (APS) is well recognized, but the underlying pathophysiology remains incompletely elucidated. Several findings suggest the role of complement system (CS) in the pathogenesis of antiphospholipid syndrome (APS). The importance of CS in APS is understandable since complement-derived inflammatory mediators increase vascular permeability, activate platelets and promote release of cytokines from monocytesthat favor systemic inflammation and coagulation. It has been demonstrated in a mouse model of aPL-induced pregnancy loss that complement activation can amplify the fetal injury. CS activation has been also documented in patients with APS, but there are far fewer clinical data.File | Dimensione | Formato | |
