Antiphospholipid Syndrome: A Comprehensive Clinical Review

Le résumé fourni par la source

Background: Antiphospholipid syndrome (APS) is a rare systemic autoimmune disease characterized by persistent antiphospholipid antibodies (aPL) in combination with recurrent thrombosis in the veins and/or arteries, obstetric morbidity, and various non-thrombotic associated complications. APS can be primary, as an isolated condition, or secondary in the context of another autoimmune disease, especially systemic lupus erythematosus. This comprehensive clinical review aims to summarize the current understanding of APS pathogenesis, diagnostic approaches, and treatment strategies for this unique clinical entity. Methods: A comprehensive review of the existing literature on APS was conducted, focusing on pathophysiological mechanisms, current diagnostic criteria, and therapeutic approaches. Results: APS pathogenesis involves complex interactions between aPL, phospholipid-binding proteins, and the coagulation cascade. Apart from the cardinal features of thrombosis and APS-related obstetric morbidity, APS is associated with a wide spectrum of clinical manifestations. Diagnosis remains challenging due to overlapping symptoms with other conditions, and clinicians should maintain a high index of suspicion in order to set the diagnosis. The recently published 2023 ACR/EULAR criteria although not definitive for clinical decision-making, these criteria offer clinicians a valuable tool to aid in determining whether further investigation for APS is warranted. Continued refinement of these criteria through ongoing feedback and updates is anticipated. Treatment strategies center on anticoagulation, but individualized approaches are necessary. Conclusions: Early diagnosis and multidisciplinary management of APS are critical to reducing morbidity and improving outcomes. Moreover, familiarization with the 2023 ACR/EULAR criteria is encouraged, recognizing that ongoing feedback and updates will contribute to their ongoing refinement and improvement. While VKAs remain the mainstay of treatment for most APS patients further research is needed to optimize treatment strategies and deepen our understanding of APS’s underlying disease mechanisms.
