Abstract
To investigate the effects of pre-conception thromboprophylaxis among patients with recurrent spontaneous abortion and antiphospholipid syndrome. A randomized placebo-controlled trial enrolled patients with a history of recurrent spontaneous abortions and antiphospholipid syndrome who attended an Egyptian center between January 2011 and June 2013. Using a computer-generated sequence, patients were randomly allocated to receive 41 mg enoxaparin subcutaneously plus 81 mg aspirin daily pre-conception, or to receive placebo pre-conception. All patients received enoxaparin and aspirin following identification of fetal heart pulsation. The primary outcomes were live-birth rate and clinical-pregnancy rate at 0-6 months, and at 6-12 months. Intention-to-treat analyses were performed. Clinicians, investigators, and data analysts were masked to the treatment assignments. The study enrolled 180 patients(90 in each group). No significant difference was observed between the intervention and control groups in the live-birth rate (67[74%] vs 59[66%]; P=0.25). At 0-6 months, the clinical-pregnancy rate was higher in the intervention group (50[56%]vs 30[33%], P=0.02). No significant difference between the intervention and control groups was obs...Continue Reading
