New biomarker may help diagnose ectopic pregnancies

04.11.2010
Novel serum test may help diagnose early pregnancy location and outcome

Researchers may have identified a promising novel diagnostic biomarker for ectopic pregnancy, according to a study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). In the western world, deaths from ectopic pregnancy are not common but in the developing world one in ten women who are admitted with an ectopic pregnancy die.

An ectopic pregnancy is an abnormal pregnancy that occurs outside the uterine cavity. Most ectopic pregnancies take place in the Fallopian tube but implantation can also occur in the cervix, ovaries and abdomen. Ectopic pregnancy is associated with severe pelvic pain and the need for a blood transfusion. The condition is a leading cause of pregnancy-related first trimester deaths.

"Finding a simple and cost-effective test using biomarkers to diagnose ectopic pregnancies would have a significant impact on reducing emotional distress and unnecessary deaths," said Andrew Horne, PhD, of the University of Edinburgh in the United Kingdom and lead author of the study. "Our study shows that placental growth factor (PIGF), a key molecule in the formation of blood vessels, is a promising novel diagnostic biomarker for ectopic pregnancies."

In this study, researchers obtained trophoblast samples from 40 pregnant women aged 18-45 years undergoing surgical termination of pregnancy, evacuation of uterus for embryonic missed miscarriage or surgery for tubal ectopic pregnancy. Trophoblasts are specialized cells of the placenta that play an important role in embryo implantation. Serum PIGF levels were measured in all trophoblast samples and researchers found that PIGF was reduced in samples from tubal ectopic pregnancies when compare to intrauterine pregnancies.

"The inevitable multiple visits and tests that are currently necessary to diagnose ectopic pregnancies are a sizable expense for health services," said Horne. "Serum PIGF may be the answer to the urgent unmet need for a biomarker for tubal ectopic pregnancy that allows quicker diagnosis and facilitates earlier and less invasive treatment. Large-scale studies are now required to determine its clinical utility."

Other researchers working on the study include: Julie Shaw, Amanda Murdoch, Sarah McDonald, Alistair Williams, Henry Jabbour, W. Colin Duncan and Hilary Critchley of the University of Edinburgh in the United Kingdom.

The article, "Placental growth factor: a promising diagnostic biomarker for tubal ectopic pregnancy," will appear in the January 2011 issue of JCEM.

Founded in 1916, The Endocrine Society is the world's oldest, largest and most active organization devoted to research on hormones and the clinical practice of endocrinology. Today, The Endocrine Society's membership consists of over 14,000 scientists, physicians, educators, nurses and students in more than 100 countries. Society members represent all basic, applied and clinical interests in endocrinology. The Endocrine Society is based in Chevy Chase, Maryland.

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
