[Immunologic aspects on the etiology of pregnancy toxemia].

Since 70 years ago, the possibility that the etiology of Gravidic Toxemia is inmunologic has been studied. Several researchers agree in the disminution of the levels of IgG with no modifications on the levels of complement fractions. The determination of IgA, IgM, IgC, C3 and C4 was made on fifteen pacients with gravidic toxemia and fifteen pacients that presented no complicated pregnancy. The results are the same as the reported facts like disminution of IgG, it was observed also, a disminution on the complement fractions C3 and C4. The research let us stabblish the posibility of a sikness caused by immune complexs having as an antigenic stimulations the trofoblast.
