Potential driver of severe early-onset preeclampsia identified
Severe early-onset preeclampsia has confounded doctors for more than 2,000 years. It can strike as early as 20 weeks into pregnancy, sending blood pressure soaring and putting both the mother and baby at risk.
Severe early-onset preeclampsia, a condition that can pose serious risks to both mother and baby, has puzzled medical professionals for millennia. A team of researchers led by pregnancy specialist Thomas L. Brown, Ph.D. from Wright State University may have discovered a critical factor behind this dangerous pregnancy complication, potentially paving the way for a treatment without medication.
The researchers found that women suffering from severe early-onset preeclampsia exhibited significantly higher levels of extracellular vesicles—tiny cellular particles—compared to women with healthy pregnancies. Lab tests showed that reducing these particle levels to normal restored normal blood vessel function. If a safe method can be developed to lower extracellular vesicle counts in women with severe preeclampsia, it could prevent the condition's blood vessel dysfunction, potentially averting dangerously high blood pressure.
This research, published in the prestigious Hypertension journal, could lead to improved outcomes for women and babies affected by this life-threatening pregnancy disorder.
