HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome versus severe preeclampsia: onset at < or =28.0 weeks' gestation
Our purpose was to determine whether the onset of the HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome in women at < or =28.0 weeks' gestation is associated with an increased risk of adverse maternal and perinatal outcomes in comparison with the risk for women with severe preeclampsia but without the HELLP syndrome at a similar gestational age. Sixty-four patients with either the HELLP syndrome (n = 32) or severe preeclampsia but absent HELLP syndrome laboratory test results (n = 32), admitted at < or =28.0 weeks' gestation between July 1, 1992, and April 30, 1999, were studied. Maternal and perinatal outcomes were compared between the 2 groups. Statistical analysis was performed by the Student t test and the Fisher exact test. There were no significant differences between the 2 groups regarding African-American race (59% vs 75%), nulliparity (50% vs 56%), or the use of corticosteroids (59% vs 78%). There were no maternal deaths. One woman with the HELLP syndrome had a liver hematoma. The rate at which transfusion of blood products was required was significantly greater in women with the HELLP syndrome than in those with severe preeclampsia only (25% vs 3%; P <.05). There were no significant difference...Continue Reading

Blood Clotting Disorders
Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
