Various parameters of the haemostatic and, more importantly, of the fibrinolytic systems were examined in 5 patients with severe pre-eclampsia/eclampsia. All 5 showed signs of haemolysis, elevated liver enzymes and low platelet count (HELLP syndrome). A significant decrease in platelet count (46.4 X 10(9)/litre) and an increase in beta-thromboglobulin (137 ng/ml) were observed in the HELPP patients in comparison with normal pregnant women (267 X 10(9)/litre and 49.3 ng/ml, respectively). No significant differences in fibrinogen levels, activated partial thromboplastin time, prothrombin time and fibrin(ogen) degradation products between the HELLP patient group and the normal pregnant group were observed. However, the antigenic levels of tissue-type plasminogen activator and type 1 plasminogen activator inhibitor were significantly higher in the HELLP pre-eclamptic women than in gestational age-matched controls. In contrast, the antigen levels of type 2 plasminogen activator inhibitor were significantly lower in the patients. These results indicate that platelet activation and alterations in plasminogen activator inhibitors type 1 and type 2 may be involved in the pathophysiological pathway of this syndrome.

Some studies suggest that soluble thrombomodulin (TM) could be used as a marker of preeclampsia or eclampsia. However little is known about the sequential changes of TM during the course of normal pregnancy. Levels of TM were determined in 100 women with uneventful pregnancies. Samples (n = 394) were divided into five study intervals, three during pregnancy, one at delivery and one three days postpartum. As compared with TM levels (median 34.3 ng/ml, range 17.6-61) of a control group of 60 healthy non-pregnant women, TM levels were shown to increase throughout pregnancy, median (and range) values being respectively 38.5 (17.6-72.7) from 11 to 20 weeks, 45.2 (22.6-75.2) from 21 to 30 weeks and 54.3 (25.1-114.5) ng/ml from 31st week to delivery. One hour after delivery TM levels were still elevated and dropped three days postpartum to 40.5 (20.9-79.4) ng/ml. The increase of TM levels was correlated with those of tissue-type plasminogen activator and plasminogen activator inhibitor-1 antigens. The large overlap in TM levels between the study periods seems to preclude a clinical use of TM based on reference values from a control group. Our data suggest that it would be more appropriate to take into account TM baseline values in a given woman to examine her TM increase during pregnancy.
