Summary
Antiphospholipid syndrome (APLS) involves circulating antibodies causing blood clots, pregnancy loss, and low platelets. It often occurs with autoimmune diseases, leading to vascular damage and thrombosis.
Area of Science:
- Immunology
- Pathology
- Hematology
Context:
- Antiphospholipid syndrome (APLS) is a significant autoimmune disorder.
- Characterized by specific autoantibodies and clinical manifestations.
Purpose:
- To detail the pathogenesis and morphological features of Antiphospholipid Syndrome.
- To highlight the association with other medical conditions.
Summary:
- APLS is defined by antiphospholipid antibodies, recurrent thrombosis (arterial/venous), pregnancy loss, and thrombocytopenia.
- It frequently co-exists with autoimmune diseases like lupus erythematosus, neoplasms, and infections.
- Pathogenesis involves antibody-mediated endothelial damage, promoting thrombosis and impairing fibrinolysis.
- Morphological findings include thrombosis, angiomatosis, hemorrhage, and vascular alterations without significant inflammation, potentially involving vasculitis.
Impact:
- Enhances understanding of APLS pathophysiology.
- Provides a basis for improved diagnostic criteria and therapeutic strategies.
