The scientific director of the Meharry Center for Women’s Health Research in Nashville and a team of University of Texas researchers have concluded that inhibiting the activity of an enzyme during pregnancy can reduce the incidence of pre-term births in rats.
Also, the enzyme, catechol-O-methyltransferase (COMT), appears to stop the cervix from expanding and stretching, the research showed.
These findings were reported in a recent issue of the specialized journal Reproduction.
“These are important findings, because this study also provides for the first-time a urinary biomarker that may potentially help us predict whether a pregnant woman is at risk for pre-term labor or not,” said Dr. Ayman Al-Hendy, who is a professor and vice chair of the Department of Obstetrics and Gynecology at Meharry Medical College.
Pre-term labor occurs when a pregnant woman delivers at fewer than 37 weeks. The incidence of pre-term births has risen in the last 10 years, from 10 percent to 13 percent, according to Al-Hendy, and more than 1 million pre-term births occur annually, placing a financial impact on the healthcare system between $7 and 8 billion dollars a year.
“Historically, there has not been an effective way to predict pre-term labor and providing effective treatment once it occurs has been even more challenging,” said Al-Hendy.
Pre-term labor is also a health disparities issue. According to Al-Hendy, African-American women are 3-4 times more likely to suffer from the condition.
Prevention of human pre-term labor is still years away, however, Al-Hendy said he and his team are encouraged by the findings from this study — the results of which may prompt researchers to initiate clinical trials in humans.
In addition to Al-Hendy, co-authors of the study include the following: Melissa J. Wentz, Shao-Qing Shi, Leili Shi, Salama A. Salama, Hassan M. Harirah, Hala Fouad, Robert E. Garfield, department of obstetrics and gynecology, University of Texas Medical Branch.
