Relation between Plasma Endothelin 1 Levels and T Helper 1: T Helper 2 Cell Immunity in Women with Preeclampsia

Relation between Plasma Endothelin 1 Levels and T Helper 1: T Helper 2 Cell Immunity in Women... The aim of this study was to investigate the relationship between plasma endothelin 1 (ET-1) levels and T helper (Th)-1:Th2 cell immunity in women with preeclampsia. The percentage of Th1 and Th2 cells and the Th1:Th2 cell ratios in peripheral blood from 11 normal pregnant women and 11 patients with preeclampsia at 29–34 weeks of gestation were calculated using flow cytometry. The plasma ET-1 level was also determined using a modified radioimmunoassay. The plasma ET-1 concentrations and the Th1:Th2 cell ratios in normal pregnancies were significantly lower than those in patients with preeclampsia. Negative correlations were found between plasma ET-1 levels and Th2 cells in both the preeclamptic pregnancy groups and in the normal pregnant women. Our results indicate that elevated ET-1 levels are associated with a Th1:Th2 imbalance in preeclampsia. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Gynecologic and Obstetric Investigation Karger

Abstract

The aim of this study was to investigate the relationship between plasma endothelin 1 (ET-1) levels and T helper (Th)-1:Th2 cell immunity in women with preeclampsia. The percentage of Th1 and Th2 cells and the Th1:Th2 cell ratios in peripheral blood from 11 normal pregnant women and 11 patients with preeclampsia at 29–34 weeks of gestation were calculated using flow cytometry. The plasma ET-1 level was also determined using a modified radioimmunoassay. The plasma ET-1 concentrations and the Th1:Th2 cell ratios in normal pregnancies were significantly lower than those in patients with preeclampsia. Negative correlations were found between plasma ET-1 levels and Th2 cells in both the preeclamptic pregnancy groups and in the normal pregnant women. Our results indicate that elevated ET-1 levels are associated with a Th1:Th2 imbalance in preeclampsia.
