[Catastrophic antiphospholipid syndrome].

Catastrophic antiphospholipid syndrome is the most dangerous form of the antiphospholipid syndrome, which is characterized by rapid onset of thrombosis in small vessels of many organs and intravascular coagulation, thrombocytopenia and hemolytic anemia. The syndrome develops over a short period of time with acute multi-organ failure, including kidney, respiratory, cardiovascular, central nervous system and adrenal glands, often associated with disseminated thrombotic microangiopathy. The catastrophic antiphospholipid syndrome involves three or more systems, organs and/or tissues, the development of symptoms must occur within less than one week, it is necessary to confirm the histopathological vascular occlusion in at least one organ or tissue, and laboratory confirmation of the presence of antiphospholipid antibodies in the serum on two occasions over an interval of 12 weeks. This syndrome is characterized by a high mortality despite the use of optimal treatment. Early diagnosis and aggressive treatment of patients with catastrophic antiphospholipid syndrome is essential to save the life of these patients. In the last 10 years, the mortality in this disease decreased from 50% to 30% with simultaneous treatment with anticoagulants, corticosteroids, plasmapheresis and immunoglobulins.
