title: Relation of antiphospholipid antibody and placental bed inflammatory vascular changes to the outcome of pregnancy in successive pregnancies of 2 women with systemic lupus erythematosus.
abstract: Histological changes in biopsies from the placental and placental bed in 2 successive pregnancies of 2 women with systemic lupus erythematosus and antiphospholipid antibodies were studied. In one of the first 2 pregnancies vasculitis was found in the spiral arteries of the placental bed biopsy, while the other showed perivascular inflammatory infiltration and deciduitis. This was associated with poor pregnancy outcome and elevated antiphospholipid antibodies (aPL). In the subsequent 2 pregnancies prednisolone treatment was tailored to suppress the aPL titer with markedly decreased inflammatory changes and no evidence of vasculitis in the spiral arteries of the placental bed was found. This was associated with a normal pregnancy outcome. A causal relationship between aPL and inflammatory vascular changes in the placental bed as well as a beneficial effect of the corticosteroid treatment in those two women in suggested.
