Esomeprazole and sulfasalazine in combination additively reduce sFlt-1 secretion and diminish endothelial dysfunction: potential for a combination treatment for preeclampsia

Abstract

Development and repurposing of therapies that show promise in the prevention or treatment of preeclampsia would be a major advance for the obstetrics field. We recently identified esomeprazole and sulfasalazine as potential candidates for the treatment of preeclampsia. Both reduce placental and endothelial secretion of sFlt-1 and sENG and mitigate endothelial dysfunction in vitro. Here we assessed whether esomeprazole and sulfasalazine in combination would additively attenuate the elevated release of anti-angiogenic factors and markers of endothelial dysfunction, key characteristics of preeclampsia. Primary placental tissue and cells, and primary endothelial cells were treated with esomepraz..
