Pre-eclampsia, a potentially deadly disorder that strikes about 5% of pregnant women, may be an autoimmune disease, Texas researchers reported Monday in the journal Nature Medicine. The team injected mice with antibodies isolated from women with the disorder, and the mice showed symptoms of the problem, including dangerously high blood pressure, protein in the urine and placental abnormalities. The effects of the antibodies could be blocked with the drug losartan, but the medication cannot be used in pregnant women because it can harm a fetus.

Vitamin D deficiency increases the risk of life-threatening preeclampsia during pregnancy five-fold, Pennsylvania researchers reported Friday. Some researchers have suspected that low levels of vitamin D contribute to the disorder, which is characterized by soaring blood pressure and swelling of the hands and feet, but the new study is the first to examine its role directly.

Two proteins secreted by the placenta may be responsible for virtually all cases of preeclampsia, a severe complication of pregnancy that can be fatal to a mother or her baby, researchers report today. Abnormally high levels of the proteins could be used to predict the development of the disorder weeks before symptoms occur, experts said, and the findings suggest new ways to treat the problem.

Taking multivitamins around the time of conception dramatically reduces a woman's risk of preeclampsia, a complication during pregnancy that can be lethal to a woman and her fetus, researchers at the University of Pittsburgh report. Women who took multivitamins at least once a week three months before the start of pregnancy and three months after were 45% less likely to develop preeclampsia compared with women who did not take supplements, the study found.

A disappointing new study has found that vitamin C and E supplements given to healthy pregnant women do not reduce their risk of developing preeclampsia, a complication that can be lethal to both the woman and her fetus. Preeclampsia happens when vessels in the womb constrict, cutting off blood and oxygen to the fetus. It occurs in late pregnancy and produces an increase in blood pressure. The condition kills about 76,000 women and fetuses a year worldwide.

Researchers have made a major step toward the diagnosis and possible treatment of preeclampsia, a sometimes lethal complication of pregnancy that affects as many as 200,000 American women each year. A team in Boston and Washington found that the levels of one protein in the blood of pregnant women were sharply elevated and those of another protein were abnormally low as much as five weeks before the women developed preeclampsia.
