ETIOLOGY We propose that the endothelial dysfuction observed in pre-eclamptic women from developing countries seems to be mainly related to nutritional deficiencies as calcium intake, subclinical infections and metabolic disorders, while in developed countries the genetic and immunological alterations seem to be the most probable factors responsible for the development of PE, and it is related with the quality of the prenatal care system.

METABOLIC SYNDROME These results support the proposal that in Andean women at high risk of PE, after the calcium deficit is resolved and the subclinical infections are treated, the metabolic syndrome can be, together with genetic and immunological factors, the responsible cause for the remainder incidence of PE Lopez-Jaramillo et al.
