Antiphospholipid Syndrome (APS)

Flashcards
0/15
Pregnancy Management in APS
Combination of low-dose aspirin and heparin (usually low molecular weight heparin) to reduce the risk of miscarriage and other complications.
Main Clinical Manifestation of APS
Thrombosis, which can occur in both arterial and venous systems, often leading to conditions such as deep venous thrombosis or stroke.
Livedo Reticularis in APS
A mottled discoloration of the skin often seen in APS patients, believed to be due to microvascular thrombosis.
Antiphospholipid Antibodies
Autoantibodies targeted against phospholipid-binding proteins including lupus anticoagulant, anticardiolipin antibodies, and anti-beta-2 glycoprotein I.
Definition of APS
An autoimmune disorder characterized by the presence of antiphospholipid antibodies causing thrombosis and/or pregnancy-related complications.
APS Diagnostic Criteria
Requires one clinical (vascular thrombosis or pregnancy morbidity) and one laboratory (presence of antiphospholipid antibodies) criterion for diagnosis.
Common Obstetric Manifestation of APS
Recurrent miscarriages, which are often seen as a hallmark of APS in the obstetric population.
Management of Thrombotic Events in APS
Long-term anticoagulation therapy is the mainstay treatment to prevent new thrombotic events, using vitamin K antagonists like warfarin or direct oral anticoagulants (DOACs).
Primary vs Secondary APS
Primary APS occurs in the absence of any other related disease, whereas Secondary APS is associated with another autoimmune disorder, commonly Systemic Lupus Erythematosus (SLE).
Catastrophic APS
A rare, severe form of APS characterized by multiple organ thromboses and a high risk of morbidity and mortality, requiring aggressive anticoagulation and immunosuppression.
Thrombocytopenia in APS
A common hematological finding in APS, usually mild and does not typically result in bleeding, despite low platelet counts.
Pediatric APS
Children can also be affected by APS, presenting similarly to adults with thrombosis and requiring similar management strategies.
The Role of Immunoglobulins in APS
Intravenous Immunoglobulin (IVIG) may be used in refractory APS, particularly in the setting of catastrophic APS or when anticoagulation alone is insufficient.
Role of Aspirin in APS
Used prophylactically in low-risk APS patients to reduce the likelihood of thrombotic events due to its antiplatelet effects.
INR Target for Warfarin Therapy in APS
The target INR in APS patients on warfarin is typically 2-3 for venous thromboembolism and 2.5-3.5 for arterial thrombosis.
