Preeclampsia is a common disorder of pregnancy resulting in increased blood pressure and end organ effects. The pathogenesis of preeclampsia is multi-factorial. Arginine vasopressin (AVP) is increased in preeclampsia, and the chronic infusion of AVP throughout gestation has previously been shown to be sufficient to produce a phenotype of preeclampsia in C57BL/6J mice representative of some of the cardiovascular and renal events seen in humans. Alterations in T-helper cell populations and their effector cytokines are also known to occur in preeclampsia. Therefore, we proposed that the increased secretion of AVP may be responsible for the immune changes that occur in preeclampsia. We also hypothesized that known pharmacological AVP antagonist, vaptans, may be able to reverse the effects of AVP infusion.
