Successful treatment in two women with antiphospholipid antibodies and refractory pregnancy losses with intravenous immunoglobulin infusions.

In two women with antiphospholipid antibodies and recurrent fetal losses refractory to usual treatments, therapy consisting of aspirin, heparin, and intravenous gamma-globulin infusions was successful. Production of antiphospholipid antibodies was not suppressed. The transient decrease in anticoagulant activity noted in one case was not reproduced in vitro and was probably not physiologically important.
