title: [Circulating anticoagulants excluding hemophilia. Multicenter survey undertaken under the aegis of the French National Society of Internal Medicine apropos of 207 cases].
abstract: A retrospective multicentre study, undertaken under the aegis of the French National Society of Internal Medicine, involved 200 subjects with acquired circulating anticoagulants; 130 were female and 77 were male; mean age was 45 +/- 23 years (range: 10 months to 80 years). Mean duration of follow-up was 23 months. In 130 subjects the anticoagulants were detected as a result of a systematic screening examination. The main overt clinical manifestations were haemorrhages, venous or arterial thrombosis and spontaneous abortion. Typing of the anticoagulant, performed in 166 cases, showed the presence of an antiprothrombinase in 141; this enzyme is not responsible for severe bleeding unless it is associated with other disorders of coagulation; less frequent were an anti-factor VIIIc (n = 16) and an anti-factor V (n = 2) anticoagulants. An underlying pathology was found in 172 subjects, including systemic lupus erythematosus (n = 60), induced lupus (n = 11), discoid lupus (n = 3), infection (n = 23), blood disease (n = 19), cancer (n = 15) and vasculitis (n = 15); other factors were pregnancy (n = 5) and medicines (n = 6). The anticoagulant disappeared spontaneously in 10 cases and in 33 of the 115 subjects treated. In subjects with lupus and in children under twelve years of age, an antiprothrombinase was regularly identified at typing.
