Study Reports Significant Increase in Incidence of Preeclampsia, a Potentially Life-Threatening Pregnancy Complication

FRAMINGHAM, Mass.–(BUSINESS WIRE)–A study published recently in the American Journal of Perinatology
reports a dramatic increase in the incidence of preeclampsia in the
United States. Preeclampsia and early onset preeclampsia have grown 67
percent and 140 percent respectively over the past two decades. The rise
in this life-threatening condition outpaces that of some of the United
States’ most challenging public health concerns, including diabetes,
obesity and Alzheimer’s disease. Preeclampsia is one of the top six
causes of maternal mortality in the United States and is associated with
infant death and potentially lifelong complications for the mother and

Preeclampsia is a complication of pregnancy that typically develops
after 20 weeks gestation. Early onset preeclampsia is a severe form that
occurs before 34 weeks gestation. The condition is characterized by high
blood pressure and is thought to be the result of an abnormal
interaction of the placenta with the mother’s cardiovascular and immune
systems. Today, the only definitive treatment for preeclampsia is
delivery of the newborn regardless of gestational age.

Mothers with preeclampsia account for approximately 10 percent of births
before 34 weeks gestation. Preterm infants, particularly those born at
or before 28 weeks, have a greater likelihood of cardiovascular and
respiratory diseases as well as higher rates of disability, cognitive
delays and behavioral or psychological effects.

“This study demonstrates the growing impact of preterm preeclampsia on
pregnant women, their newborns and society,” said Michael Paidas,
M.D., Professor & Vice Chair, Obstetrics, and Director, Yale Women and
Children’s Center for Blood Disorders and Preeclampsia
Advancement, Department of Obstetrics, Gynecology and Reproductive
Sciences, Yale School of Medicine and a senior author of the study. “The
importance of identifying an effective treatment to prolong pregnancy
and treat preeclampsia cannot be underestimated.”

The study authors call for additional research and assessments to obtain
greater understanding of the societal and economic impact of the disease.
