Description of intervention(s) / exposure
Prospective, randomized, controlled pilot study of aspirin plus nitric oxide donors treatment of recurrent abortion due to primary antiphospholipid syndrome

Two groups of pregnant with history of recurrent abortion due to primary antiphospholipid syndrome. The control group was treated with acetyl salicylic acid 81 mg oral tablets (low dose aspirin) alone once daily and the study group was treated with low dose aspirin 81 mg oral tablets plus 20 mg isosorbid mononitrate tablets applied vaginally once daily. Treatment in both groups started once pregnancy was confirmed by B-hGC and ultrasound examination and continued till the end of pregnancy. All patients were firmly instructed to adhere to treatment through regular antenatal care followup and drug tablet return

Result was represented by the mean and the standard deviation. Student t test was used to compare between two independent groups, the paired t test was used to compare the results in the same group before and after intervention and the Z test to compare between two proportions. P value of = 0.05 was considered significant.

Summary
Brief summary
Antiphospholipid syndrome (an autoimmune disease) is important cause for recurrent abortion (Three or more spontaneous successive abortion). Low dose aspirin and low molecular weight heparin are used for treatment on the assumption that the disease leads to placental thrombosis and fetal demise but results of treatment are unsatisfactory. Recently, abnormal endogenous nitric oxide synthesis was alleged to play a role.This study was performed to know if treatment with nitric oxide donors (drugs the release nitric oxide in the body) will improve pregnancy outcome and the full term live birth rate
