Nitrogen Oxide (NO) in the Pathogenesis of Preeclampsia

Abstract

The concentrations of nitric oxide (NO) donors in the plasma of pregnant women with preeclampsia is several times higher than in healthy pregnant women. Antihypertensive drugs acting not through the NO-mediated mechanisms normalized BP in some women with preeclampsia, but did not significantly reduce the levels of NO donors in the plasma. It appears that preeclampsia is associated with insufficient NO availability for the targets, rather than low intensity of NO synthesis. The concentration of NO donor molecules in the plasma can therefore be a useful additional diagnostic marker of preeclampsia.

Keywords: dinitrosyl iron complexes (DNIC); nitrate; nitrite; nitrogen oxide (NO); preeclampsia.
