Treating preeclampsia with sildenafil may protect offspring's cardiovascular health: Study.
Summary: Washington D.C. [USA], Apr 6 (ANI): A new research conducted in rats has found that treating preeclampsia with sildenafil citrate (Viagra) may help protect the cardiovascular health of the offspring.
Washington D.C. [USA], Apr 6 (ANI): A new research conducted in rats has found that treating preeclampsia with sildenafil citrate (Viagra) may help protect the cardiovascular health of the offspring.
The research was presented at the American Physiological Society's annual meeting, Experimental Biology 2019.
An estimated six to 15 million people in the United States are children born of a pregnancy complicated by preeclampsia.
Preeclampsia occurs when women with otherwise normal blood pressure experience elevated blood pressure during pregnancy.
Children of women with preeclampsia during pregnancy have higher blood pressure during childhood and almost double the risk of stroke later in life.
"The ultimate goal of our work is to improve the long-term health of women and children affected by preeclampsia," said Hannah Turbeville, a researcher.
"There are limited guidelines for addressing the health risks to these groups, and we hope not only to bring attention to these risks but also to propel research forward that will inform preventative interventions," said Turbeville.
In previous work, the researchers found that sildenafil citrate, which lowers blood pressure by acting on the nitric oxide pathway, can treat preeclampsia in a rat model of the condition while also decreasing blood pressure in offspring.
In the new work, they wanted to determine how sildenafil citrate affects the offspring's response to stressors that normally increase blood pressure.
To mimic human preeclampsia as much as possible, the researchers used a rat model that develops the condition without a procedure or drug. They then exposed the offspring to a stressor that increases blood pressure.
The researchers observed smaller increases in blood pressure for male offspring of rats treated with sildenafil citrate compared to those that did not receive treatment or received a more commonly used blood pressure medication. The protective effect was not apparent in female offspring.
"Our studies demonstrate the potential for targeted therapy of the nitric oxide pathway to improve the body's response to stressors in the later lives of children of women who experienced preeclampsia," said Turbeville.
"This pathway plays an important role in improving blood flow and lowering blood pressure," he added.
The researchers are working to better understand the gender-specific response to sildenafil citrate. They are also exploring whether the improved response to stressors leads to decreased risk of chronic diseases such as high blood pressure and chronic kidney disease when these offspring become adults.
