Dubbed the "Congo Red Dot Test" by the research team, the test accurately predicted preeclampsia in a study of 347 pregnant women, allowing health care providers to offer better preventive care to pregnant women. The research will be presented February 4 at the Annual Scientific Meeting of the Society for Maternal Fetal Medicine (SMFM) in Chicago.
The World Health Organization estimates that about 63,000 pregnant women die each year because of severe preeclampsia, as well as a related condition called eclampsia, which can cause sudden, convulsive seizures.
"There is a critical need in the developing world for low-cost diagnostics for preeclampsia," said lead researcher Irina Buhimschi, M.D., associate professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale School of Medicine. "This test will help identify high-risk patients that should be transported from remote settings to facilities where there is access to specialized care for preeclampsia, such as magnesium sulfate therapy."
Buhimschi said that despite its effectiveness in preventing eclamptic seizures, magnesium sulfate is underutilized in developing countries. This is due in part to the lack of consistent and low-cost ways to identify preeclampsia patients who are in need of intervention, which the test could provide. She said that the test could also identify women who needed to deliver their babies immediately, in turn reducing the incidence of unnecessary early birth, because delivery is the only effective treatment for preeclampsia.
The team also found that the Congo Red Dot Test could be used as a marker for assessing misfolded proteins. The test is based on a common red dye, originally used to stain textiles, that sticks to misfolded proteins. Previous studies by Buhimschi and her team have found that preeclampsia is a pregnancy-specific protein misfolding disease.
"In this new work, we have seen a link between preeclampsia and other disorders caused by misfolded proteins such as Alzheimer's or prion disease," said Buhimschi. "This may provide the foundation for new therapeutic approaches to reduce the burden of this disorder."
Other Yale School of Medicine authors on the study included Edmund Funai, Guomao Zhao, Antonette Dulay, Sarah Lee, Christina Han, Erika Werner, Stephen Thung and Catalin Buhimschi.
The research was funded by a McKern Award for Perinatal Research.

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
