PROSTAGLANDIN EXCRETION IN PREECLAMPSIA

目前认为前列腺素代谢紊乱是其中之一

A disturbance of prostaglandin metabolism is currently believed to be one of the major mechanisms in the pathogenesis of preeclampsia. Most previous studies of this theory, however, have included only women who had already developed clinically overt disease. In order to investigate whether prostaglandin abnormalities precede the onset of preeclampsia, we have designed a nested case-control study using stored urine specimens prospectively collected as early as thirteen weeks gestation from women participating in the NICHD Trial of Calcium to Prevent Preeclampsia (CPEP). In this study, we are comparing the urinary excretion of prostaglandin and thromboxane in preeclampsic women before the diagnosis of preeclampsia to that in normal pregnant women at comparable gestational ages. The laboratory analyses have been completed and data analysis is ongoing.
