Complement activation, circulating protease inhibitors and pregnancy‐associated proteins in severe preeclampsia

Abstract
Summary.Circulating protease inhibitors, pregnancy‐associated proteins and the split product of complement factor 3 (C3d) were measured in 14 women with severe pre‐eclampsia and their matched controls. Only the mean levels of antithrombin III were observed to be significantly lower in pre‐eclampsia (P<0.02).
