INTRODUCTION: The discovery of new treatments that prevent or treat preeclampsia
would be a major advance. Antiangiogenic factors soluble fms-like tyrosine
kinase-1 (sFlt-1) and soluble endoglin (sENG) are secreted in excess from the
placenta, causing hypertension, endothelial dysfunction, and multiorgan injury.
We recently identified metformin and esomeprazole as potential treatments for
preeclampsia. Both reduce placental and endothelial secretion of sFlt-1 and
soluble endoglin, and reduce endothelial dysfunction. OBJECTIVES: We set out to
assess whether combining metformin and esomeprazole would additively reduce
sFlt-1 and soluble endoglin secretion and reduce endothelial dysfunction (verses
drug alone). Metformin and esomeprazole were added to primary placental cells and
tissues, and endothelial cells and their effects on sFlt-1 and soluble endoglin
secretion were assessed in vitro. Tumor necrosis factor-? (TNF-?) was added to
endothelial cells to induce dysfunction in vitro. We examined the ability of
metformin + esomeprazole to rescue TNF-? induced vascular cell adhesion
molecule-1 (VCAM-1) and Endothelin-1 (ET-1) expression, leukocyte adhesion
(markers of endothelial dysfunction). RESULTS: Combining metformin and
esomeprazole was additive at reducing sFlt-1 secretion and expression of sFlt-1
e15a mRNA isoform in primary cytotrophoblast, placental explants and endothelial
cells. In contrast, no additive reduction in sENG was observed with combined
metformin and esomeprazole. The low-dose combination of metformin + esomeprazole
additively reduced TNF-?-induced VCAM-1 mRNA, but not VCAM-1 protein expression.
There was no additive reduction when combining metformin and esomeprazole on
TNF-? induced PBMC adhesion to endothelial cells. However, combining metformin
and esomeprazole additively reduced ET-1 mRNA expression. CONCLUSIONS: In
conclusion combining metformin and esomeprazole additively reduced secretion of
sFlt-1, and markers of endothelial dysfunction. The combination of metformin and
esomeprazole may provide a more effective treatment or prevention for
preeclampsia compared to either as single agents.
