title: Effect of betamethasone on fetal macrophage function: depression of adherence of immunoglobulin-coated red blood cells.
abstract: In this study, betamethasone was found to significantly inhibit the binding of immunoglobulin-coated O Rh-positive red cells to fetal macrophages. At a dose of 0.15 mg%, betamethasone depressed immune rosette formation to 44% of controls (p less than 0.01); and a dose of 0.60 mg% resulted in an average depression to 22%. This in vitro effect may reflect important alterations in in vivo immune function in infants delivered from mothers who have received antenatal corticosteroids.
