[Antiphospholipid antibodies in 146 women with repeated pregnancy losses].

Antiphospholipid antibodies are associated with arterial and venous thrombosis and recurrent abortions. However, the prevalence of these antibodies in repeated miscarriages varies in different reports. To obtain quantitative data with restricted criteria and discuss the origin of the variability on the literature, we investigated the presence of antiphospholipid antibodies in 146 women who had 2 or more consecutive pregnancy losses and in 99 women whose pregnancies were successful. Antiphospholipid antibodies (lupus anti-coagulant or anticardiolipin antibodies of 20 or more IgG units) were found in 45% of women with pregnancy losses and in 9% of controls (p < 0.001). The type of loss was determined according to the trimester of pregnancy and the time of the fetal loss. 68% of patients with antiphospholipid antibodies had at least one fetal loss on the second or third trimester compared with 45% of patients without fetal loss (p < 0.01). Further studies should be conducted using more rigorous definition of clinical and laboratory characteristics in a way to allow better comparison between studies.

Results of thrombolysis in the treatment of arterial ischemia of the limbs according to mode of administration.

After reviewing the principles, results and complications of thrombolytic therapy with "classical" agents (Streptokinase and Urokinase) used via intravenous, intraarterial route, or intraoperatively, and with more "modern" agents (APSAC, scuPA, tPA), we discuss the future of thrombolysis in the treatment of arterial ischemia of the limbs. Several items need to be clarified: --indication of thrombolysis among other treatments, mainly surgery, of arterial ischemia depends on the clinical staging of ischemia, its causes and the site of arterial obstruction; --method of delivery of the thrombolytic agent must provide the highest local concentration and the lowest systemic side effects; --efficacy of each thrombolytic agent must be analyzed when used in peripheral arterial ischemia, but also in other diseases such as myocardial infarction.
