Preeclampsia, lipid peroxidation, and calcium adenosine triphosphate activity of red blood cell ghosts

Article Abstract:

An increase in calcium within cells caused by a decrease in cellular calcium excretion may cause some of the symptoms of preeclampsia during pregnancy. Preeclampsia is an increase in blood pressure and urinary protein excretion during pregnancy. Researchers studied red blood cell membranes of 10 preeclamptic and 10 healthy pregnant women. Red cell membranes from women with preeclampsia were especially sensitive to lipid peroxidation, which inhibits calcium adenosine triphosphatase. This causes cells to accumulate calcium, which might lead to higher blood pressure.

Persistent abnormalities in plasma volume and renal hemodynamics in patients with a history of preeclampsia

Article Abstract:

Women with a history of preeclampsia may have abnormal blood flow to the kidneys. Preeclampsia is a condition during pregnancy characterized by hypertension, protein in the urine and excessive blood clotting. Researchers measured the volume of blood as well as blood supply to the kidneys in 26 women with a history of preeclampsia and 12 women with no such history. Women with a history of preeclampsia had lower blood volume and higher resistance to blood flow in the kidneys.

Interleukin-18 in the plasma of women with preeclampsia

Article Abstract:

Blood levels of interleukin-18 are similar in pregnant women who develop preeclampsia and pregnant women who do not, according to a study of 61 women. Interleukin-18 is involved in inflammation so researchers suspected blood levels might increase during preeclampsia. Further research may be needed to determine what role interleukin-18 plays in preeclampsia.
