PURPOSE: To evaluate the effect of aspirin treatment upon fetal loss in mice with experimental antiphospholipid syndrome (APLS). MATERIALS AND METHODS: Experimental APLS was induced in pregnant mice by passive transfer of mouse monoclonal anticardiolipin antibody. The mice were treated with high (100μg/d) or low (10μg/d) does of aspirin, using vitaminC(100μg/d or 10μg/d)as a control. The mice were assessed for the presence of lupus anticoagulants (prolonged aPTT), thrombocytopenia, degree of fetal resorption rate and mean embryo and placental weights. RESULTS: The mice with APLS had a higher fetal resorption rate(45.7± 12.2% vs 2.5 ± 0.4%, P <0.001), reduced placenta mean weight(104 ± 8 mgvs 169 ±7mg, P <0.001), prolonged aPTT (94± 14sec vs 39±4sec, P <0.001), and reduced mean platelet count(597± 186 ± 10 3 /mm 3 vs 847±51 ± 10 3 /mm 3 , P <0.001). The groupof mice with APLS, who were treated with low‐dose aspirin, had a lower resorption rate (11.1 ±9.3% vs 45.7±12.2%, P <0.001), a higher placenta mean weight (178 ± 8 mg vs 104 ± 8 mg, P <0.001), a higher mean embryo weight (1042 ± 134 mg vs 721±91 mg, P <0.001), and a lower aPTT (58±15 sec vs 94±14 sec, P , <0.001). Micewho were treated with high‐dose aspirin also had a lower resorption rate, although not as much as in the low‐dose aspirin group (34.2 ± 12.7% vs 45.7 ± 12.2%, P <0.001). CONCLUSION: Aspirin, especially in low dose, has a protective effect against obstetrical complications associated with experimental APLS.
