Based on this statement, Definite CAPS diagnosis requires:

a) Vascular thrombosis in three or more organs or tissues and
b) Development of manifestations simultaneously or in less than a week and
c) Evidence of small vessel thrombosis in at least one organ or tissue and
d) Laboratory confirmation of the presence of aPL.VDRL, which detects antibodies against syphilis, may have a false positive result in aPL-positive patients (aPL bind to the lipids in the test and make it come out positive), although the more specific test for syphilis, FTA-Abs, that use recombinant antigens will not have a false-positive result. Treatment
In people without symptoms, no treatment is required. In people with antiphospholipid antibody-associated thrombosis, anticoagulants such as warfarin are used to prevent further thrombosis. If warfarin is used, the INR is kept between 2.0 and 3.0. Direct-acting oral anticoagulants may be used as an alternative to warfarin, but not in people who are "triple positive" with all types of antiphospholipid antibody (lupus anticoagulant, anticardiolipin antibody and anti-β2 glycoprotein I antibody).Anticoagulation appears to prevent miscarriage in pregnant people. In pregnancy, low molecular weight heparin and low-dose aspirin are used instead of warfarin because of warfarins teratogenicity. People with recurrent miscarriages are often advised to take aspirin and to start low molecular weight heparin treatment after missing a menstrual cycle. In refractory cases plasmapheresis may be used. Prognosis
The long-term prognosis for APS is determined mainly by recurrent thrombosis, which may occur in up to 29% of patients, sometimes despite antithrombotic therapy.
History
Antiphospholipid syndrome was described in full in the 1980s, by E. Nigel Harris and Aziz Gharavi. They published the first papers in 1983. The syndrome was referred to as "Hughes syndrome" among colleagues after the rheumatologist Graham R.V. Hughes (St. Thomas Hospital, London, UK), who brought together the team. Research
APS ACTION (the AntiPhospholipid Syndrome Alliance for Clinical Trials and InternatiOnal Networking), is the first-ever international research network that has been created to design and conduct large-scale, multicenter clinical trials in persistently antiphospholipid antibody (aPL) positive patients. The network consists of a multidisciplinary group of physicians and investigators from around the world who are interested in antiphospholipid syndrome (APS) research. The primary mission of APS ACTION is to prevent, treat, and cure antiphospholipid antibody (aPL) associated clinical manifestations through high quality, multicenter, and multidisciplinary clinical research.
