title: Is ANP responsible for the hemoconcentration in preeclampsia?
abstract: A hypothesis is presented that high plasma concentration of alpha-human Atrial Natriuretic Peptide (ANP) might be responsible for hemoconcentration of preeclampsia (PE), mediated by increased diuresis and shift of fluid to the interstitium. ANP is known as a peptide regulating blood volume by diuresis and natriuresis, and perhaps through increased permeability in vessels. Moreover ANP is an antagonist to the renin-angiotensin-aldosterone (RAA) system, especially when this system is activated quantitatively as in pregnancy or qualitatively as in PE.
