Abstract: | Therapy with steroids and aspirin has been reported to benefit pregnancies in patients with lupus anticoagulant (LA). In this study, habitual first-trimester aborters with LA using steroids and aspirin were compared to a control group of untreated habitual aborters without LA. In habitual aborters with LA, 12 of 24 (50%) pregnancies reached the second trimester as compared to 8 of 22 pregnancies (36%) in the control group. Since the treated group did no better than the control group, LA probably is not a cause of first-trimester abortion. However, once the second trimester is reached, a 50% incidence of growth retardation was found, and 42% of fetuses died in the second or third trimester in treated LA patients. Treatment with steroids and anti-platelet aggregating agents may be necessary despite the attendant risks to prevent those sequelae in the second and third trimesters. There was a 29% live birth rate in treated LA patients; the rate was 36% in control patients. However, this rate was produced only by early intervention, which was unnecessary in the control patients. |
