Scientists identify biomarkers to detect and prevent stillbirth
New biomarkers found in maternal blood may allow doctors to prevent stillbirth, according to new research at the University of Alberta.
“When we started analyzing the blood of women who experienced stillbirth and compared them to healthy women, we noticed there’s a chemical difference,” said David Wishart, lead author and professor in the Department of Biological Sciences. “This suggested that we could predict and potentially prevent stillbirths.”
Using a mass spectrometer, Wishart and his colleagues examined maternal blood, and identified four chemicals that showed up consistently in mothers who experienced stillbirth. Combining this with demographic information about the mothers, the researchers discovered biomarkers for predicting signs of first-trimester stillbirth, including a fifth, previously unknown blood chemical, called verruculotoxin.
“Verrucotoxin is likely produced by microbes and fungi,” explained Wishart, lead of the Metabolomics Innovation Centre. “This is intriguing because there’s anecdotal information about people living in certain areas where there’s high mold instances of having high instances of stillbirth.”
Using this approach, scientists could develop tools and technology to screen for many other, preventable illnesses that affect both women and children, explained Wishart.
“This research is the tip of a bigger iceberg. By looking at the chemicals in the mother’s blood we can actually identify the risk for not just stillbirth, but a whole range of other conditions both for the mother and the fetus.”
Because there is still so little known about the verruculotoxin, further investigation and testing is required before a definite relation to stillbirth can be confirmed.
