Gene Expression In Pregnancies Complicated by Preeclampsia

Terminated
Conditions
Preeclampsia
Registration Number
NCT00919360
Lead Sponsor
University of Rochester
Brief Summary

The purpose of this study is to figure out some of the differences in bodily function between women who have preeclampsia and those who do not.

* This may eventually lead to an understanding of its cause. At this time, there is no known way to prevent preeclampsia, and the cause is not known.

* The only treatment is delivery of the baby, even if it is premature, in order to decrease the risk to the mother.

Detailed Description

* Preeclampsia is a pregnancy-related disorder that occurs in about 6% of all pregnancies.

* In its mild for, preeclampsia involves high blood pressure. More severe forms of preeclampsia can lead to more serious pregnancy complications.

* At this time, there is no known way to prevent preeclampsia, and the cause is not known. The only treatment is delivery of the baby, even if it is premature, in order to decrease the risk to the mother.

Inclusion Criteria
  • Gravidas at 32-42 weeks gestation,who have preeclampsia as defined by Sibai et al, 1997.

Not specified
Primary Outcome Measures
NameTimeMethod
Relative pattern of expression in cases and matched controls of a robust set of genes in the VEGF/sFLT mediated model for preeclampsia in the placenta and decidua1- 2 years
Secondary Outcome Measures
NameTimeMethod
Using relative expression analysis in an embedded set of control subjects, determine whether common variables e.g. labor, parity independently influence expression of these genes of interest in the tissues studied1 - 2 years
Determine the population variance for each gene of interest1 - 2 years
From this expression pattern,determine the validity of 18s ribosomal subunit as an endogenous control in this tissue.1- 2 years
