Brief summary

Adverse pregnancy outcome as recurrent abortion, premature labor and severe preeclampsia due to antiphospholipid syndrome is attributed to placental thrombosis; So, the traditional treatment is oral low dose aspirin plus subcutaneous low molecular weight heparin. Results in most studies are unsatisfactory because other pathologies do exist. Impaired synthesis of endogenous nitric oxide has been recently put forward. In this study we compare the traditional treatment with low dose aspirin plus the nitric oxide donors isosorbid mononitrate applied vaginally with the aim of improving pregnancy outcome especially the live birth rate

Interventions

Prospective, randomized controlled trial. Two groups of pregnant women each 17 cases with a history of recurrent abortion or premature labor due to antiphospholipid syndrome were randomized to a control group treated once daily with oral low dose aspirin 81 mg plus subcutaneous low molecular weight heparin 40 mg, and a study group treated once daily with low dose aspirin 81 mg plus isosorbid mononitrate 20 mg tablet applied vaginally. Treatment started once pregnancy was confirmed by B-hCG and u

Treatment started once pregnancy was confirmed by B-hCG and ultrasound examination and continued until the end of pregnancy. Adherence to the treatment was confirmed by the aspirin tablet and low molecular weight heparin vial return
