Breddin thrombagglutination test is followed up in patients with hypercoagulation states--atherosclerosis, atherosclerotic myocardiodysthrophia, angina pectoris gravis and acute myocardial infarction and hypocoagulation states--esential and symptomatic thrombopenia. TAT is positive in 88% of the patients with atherosclerosis and in patients with angina pectoris gravis and myocardial infarction TAT is Vth stage in 100%. TAT is zero stage in 91% in patients with thrombopenia and only in 9%-I stage. The term "zero stage" is introduced.

The efficacy and safety of TAT-59 (miproxifene phospate) were compared with tamoxifen citrate (TAM) in ER-positive or ER-unknown patients with advanced or recurrent breast cancer, using the double-blind method. TAT-59 and TAM were both given 20 mg/body orally for over 12 weeks in daily doses. Eligible cases were 93 in the TAT-59 group and 102 patients in the TAM group. The response rate was shown to be 30.1% (28/93) in the TAT-59 group and 26.5% (27/102) in the TAM group. Statistical equivalence between both treatments was proven at 90% confidence interval (-8.5% < or =, < or = 12.8%). Adverse reactions observed in the patients receiving TAT-59 were hot flush, nausea and vomiting, sweating, anorexia, abnormal values in liver function tests, and anemia, showing no differences from the TAM group. Leukopenia (4.9%) and thrombopenia (2.9%) reactions were found only in the TAM group. Two patients in the TAT-59 group and three in the TAM group discontinued treatment due to adverse reactions. However, these adverse reactions were reversible in both groups. In conclusion, TAT-59 was showed comparable efficacy and safety with TAM in ER-positive or ER-unknown patients with advanced or recurrent breast cancer.

A combined hemostatic defect consisting of a reduction in certain procoagulants, anticoagulants (antithrombin III-ATIII-, protein C-PC-) and components of the fibrinolytic system (plasminogen-Plg-) was demonstrated in very-low-birth-weight infants (VLBW <1,500 g) with gestational age 26-32 weeks. Sixteen of them were healthy, 28 were suffering from RDS and 24 from septicemia. The hemostatic defect was more profound in the RDS group, nevertheless increased TAT (thrombin + ATIII complex) and/or PAP values (plasmin + a2-antiplasmin complex) was a more frequent finding in the septicemic group of infants (91.8 vs. 17.9%). Moderate-to-severe thrombocytopenia was detected in a higher percentage in the septicemic (70.8%) than in the RDS group (50%), and increased D-dimers were demonstrated in 34.8 and 28.6% of the infants, respectively. Elevated TAT or PAP values were not always associated with gross coagulation abnormalities, and advanced disseminated intravascular coagulation (DIC) was only documented in 16.7% of the septicemic and 7.1% of the RDS infants. None of the VLBW neonates presented with clinical evidence of thrombosis, although hemorrhagic manifestations were apparent in 34.8 and 14.3% of the neonates with septicemia or RDS, respectively, mainly due to DIC or severe thrombocytopenia. In conclusion, increased TAT and/or PAP values are good indicators of the in vivo activation of the hemostatic system, but still their impact on sick neonates morbidity and mortality remains unknown.

Paroxysmal Nocturnal Hemoglobinuria (PNH) is a clonal bone marrow disorder which results in the loss of glycosylphosphatidyl inositol (GPI) anchors from cell membranes. As a consequence, membrane inhibitors of complement are lost rendering the cells more susceptible to complement mediated destruction. This results in hemolysis, leukopenia, thrombocytopenia and thrombophilia. Eculizumab, a monoclonal antibody to complement protein 5, has been approved for the treatment of PNH and is associated with a significant reduction in hemolysis, thromboembolic events and fatigue. We prospectively studied the effect of Eculizumab therapy on plasma markers of thrombin generation (D-Dimers, TAT), inflammation (IL-6), soluble P-selectin (sP-selectin), antigenic (TFMP) and functional (fTFMP) tissue factor bearing microparticles and total plasma microparticle ex vivo factor Xa generation (MPFXa) in eleven Eculizumab naive PNH patients. Blood sampling occurred day 1, prior to Eculizumab treatment, then on days 8,15,22,29, 43, 90. Our results demonstrate a statistically significant reduction in D-Dimer, TAT, IL-6, sP-selectin, and TFMP during the induction phase of treatment (day 1-29) which was sustained during the maintenance treatment (day 29-90). Although the serum LDH levels decreased rapidly, there was no correlation between the change in LDH and the markers of thrombin generation and inflammation. Although there was a statistically significant decrease in TFMP, this decrease did not correlate with changes in markers of thrombin generation or inflammation. Ex vivo MPFXa generation did not decrease with Eculizumab treatment suggesting continued microparticle formation despite inhibition of hemolysis. Ex vivo total microparticle FXa generation was found to have an inverse correlation with markers of thrombin generation, suggesting that in PNH patients in vivo thrombin generation occurs by a pathway independent of hemolysis and microparticle generation.
