We examined various hemostatic molecular markers in patients with disseminated intravascular coagulation(DIC), deep vein thrombosis(DVT), pulmonary embolism(PE), acute myocardial infarction(AMI), cerebral thrombosis(CT) and thrombotic thrombocytopenic purpura(TTP). Global tests were sensitive for DIC but not for pre-DIC. However, hemostatic molecular markers such as soluble fibrin were sensitive for both DIC and pre-DIC. Hemostatic molecular markers were also useful for analysis of DIC in a baboon DIC model. Activated protein C-protein C inhibitor complex and plasminogen activator inhibitor-I were useful for the diagnosis of DVT, PE, AMI or CT. These findings suggests that hemostatic molecular markers are useful for the diagnosis of various thrombotic disorders.

Patients in intensive care may be at high risk of in vivo platelet activation because comorbid conditions, such as infections, septicemia, shock, disseminated intravascular coagulation, and cancer represent procoagulant states. Hyperreactivity of platelets with or without a decline of cell count may result in thromboembolic complications potentially associated with the phenomenon of heparin-induced thrombocytopenia. We analyzed the data of 10 patients highly suspected of having heparin-induced thrombocytopenia during their intensive care treatment of 29 plus or minus 22 days. In seven patients, thrombocytopenia coincided with thromboembolic complications. Six patients had additionally undergone fibrinolytic therapy before starting activated partial thromboplastin time-adapted alternative anticoagulation with r-hirudin. In three patients, the platelet count decreased without a clinical manifestation, of heparin-induced thrombocytopenia. R-Hirudin treatment monitored by activated partial thromboplastin time and prothrombin time (PT) was effective and safe. The target value for activated partial thromboplastin time was a twofold prolongation. In four of five patients with deep venous thrombosis, a partial recanalization of the lower extremity could be achieved. Three patients with pulmonary embolism associated with deep venous thrombosis in two cases and in one additional case with an acute myocardial infarction did clinically profit from fibrinolysis with recombinant tissue plasminogen activator (rtPA) and r-hirudin treatment. Two lethal events probably caused by the underlying multimorbidity could not be prevented. No recurrence of thrombosis occurred, and there were no severe bleeding complications attributed to r-hirudin treatment. Platelet counts were significantly reduced on day 9.4 plus or minus 6.4 of heparin administration in all cases (>50% decrease related to the initial values) from 224,000 plus or minus 126,000/microL to 96,000 plus or minus 61,000/microL, and increased during rhirudin treatment to mean values of 224,000 plus or minus 126,000/microL. The heparin-induced platelet activation assay (HIPAA) assay was positive in 8/10 cases, whereas the PF4 enzyme-linked immunosorbent assay showed a positive result in four of eight analyzed cases. In four cases, the assays were concordantly positive. The PF4 enzyme-linked immunosorbent assay was not performed in two cases.

Plasma levels of activated protein C (APC)-protein C inhibitor (PCI) were significantly increased in patients with disseminated intravascular coagulation (DIC), thrombotic thrombocytopenic purpura (TTP), acute myocardial infarction (AMI), pulmonary embolism (PE), or deep vein thrombosis (DVT) and in patients undergoing hemodialysis (HD). Plasma levels of APC-alpha(1)-antitrypsin (AT) complex were significantly increased in patients with DIC and in those with TTP. Plasma levels of PCI were significantly decreased in patients with DIC, non-DIC, or TTP and in those undergoing HD. In the pre-DIC stage, the plasma levels of APC-PCI complex were significantly increased but not those of APC-alpha(1)-AT complex. These data suggest that measurements of APC-PCI complex and APC-alpha(1)-AT complex may be useful for the diagnosis of DIC. After treatment of DIC, the plasma levels of APC-PCI complex and APC-alpha(1)-AT complex were significantly decreased, but not those of PCI. Plasma levels of thrombin-antithrombin complex (TAT), plasmin-alpha(2)-plasmin complex (PPIC), D-dimer, and soluble fibrin monomer (SFM) were markedly increased in patients with DIC or pre-DIC and were moderately increased in patients with non-DIC, TTP, AMI, PE, or DVT and in those undergoing HD. The receiving operating characteristic (ROC) analysis showed that SFM and the APC-PCT complex are useful markers for diagnosis of DIC. The specificity of plasma TAT and PPIC levels was low. The positive rate of APC-PCI complex was higher than 90% with DIC, TTP, AMI, PE, and it was higher than 60% with DVT and HD. Since the APC-PCI complex was elevated not only in patients with venous thrombosis but also in those with arterial thrombosis, components of the protein C pathway might be useful markers for the diagnosis of arterial thrombosis.

A 70-year-old man with adenocarcinoma of the lung suffered from an attack of acute myocardial infarction during hospitalization. Eleven days after the heart attack, clinically obvious disseminated intravascular coagulation (DIC) occurred. The intravascular coagulation abnormalities progressed and eventually the patient died. We suspect that both lung adenocarcinoma and the insult of myocardial infarction may have contributed to the development of DIC in this patient.

A 71-year-old man with acute myelogenous leukemia (AML, M2) developed signs of chest oppression, and was diagnosed as having acute myocardial infarction (AMI). At the same time, his leukemia relapsed in association with disseminated intravascular coagulation (DIC). The patient's risk factors for AMI were hyperlipidemia, hyperglycemia, and a history of smoking. Coronary angiography showed occlusion of the circumflex branch. Percutaneous transluminal angioplasty (PTCA) was performed successfully, followed by administration of heparin. After chemotherapy, the patient's DIC improved and a second remission was attained. When elderly patients with AML show evidence of DIC, we should be aware of AMI as a possible complication. PTCA is a safe operation for such patients.

Viral hepatitis (VH) was diagnosed in 65% of patients with infectious endocarditis (IE) abusing intravenous narcotic drugs. VH caused recurrent course of IE in 8% examinees. The virusological tests of the blood for HBs-antigen or antibodies to viral hepatitis C were positive in 39 patients (group 1) and negative in 21 patients (group 2). VHB, VHC, VHB + VHC were diagnosed in 15, 57 and 28% patients, respectively. An acute course of IE was observed in 72% patients from group 1 and 76% patients from group 2, respectively, subacute course--in 20 and 24%, respectively, recurrent in 8% and 0%, respectively. IE patients with VH often had thrombohemorrhagic complications. DIC syndrome was detected in 25 and 4% patients, hemophthisis--in 33 and 28%, nephritis--in 71 and 48% patients, acute cerebral ischemia--in 7 and 4%, acute myocardial infarction--in 71 and 4%, hypocoagulation--in 53 and 8%, hypercoagulation--in 29 and 50% patients from group 1 and 2, respectively.

A 71-year-old man visited our hospital complaining of fever and a bleeding tendency. The peripheral blood WBC count was 10,400/microliter with 90% promyelocytes. The bone marrow was hypercellular with 88% promyelocytes. Disseminated intravascular coagulation was recognized. The patient was diagnosed as having acute promyelocytic leukemia and was treated with daily oral administration of all-trans retionic acid (ATRA) (45 mg/m2/day) and cytarabine (160 mg/day, intravenous drip infusion for the initial five days). The ATRA treatment induced leukemic cells to undergo mature myeloid differentiation. On day 24 after the start of treatment, the WBC count rapidly increased and acute myocardial infarction appeared, with consciousness disturbance and bilateral Babinski reflex appearing three hours later. Magnetic resonance imaging showed a fresh lacunar infarction of the right lenticular nucleus, and serum levels of IL-6 and PAI-1 were found to be elevated at the onset of infarction. Since there was a possibility that the retinoic acid syndrome (RAS) might have helped bring about the infarctions, we stopped the ATRA treatment and started administration of methyl-prednisolone (500 mg/body/day for 3 days) and gabexate mesilate. The WBC count decreased immediately and the consciousness disturbance improved. In this case, ATRA treatment might have initiated the RAS and resulted in some endothelial damage, thus causing the infarctions.

The developments and trends of hemostatic and antithrombotic drugs in Japan were investigated chronologically for the last 50 years after the 2nd World War. 1. Hemostatic drugs are classified into three groups ; capillary stabilizers, blood coagulants and antifibrinolytics. l) As to capillary stabilizers, flavonoid (rutin, 1949), adrenochrome derivative (carbazochrome, 1954) and conjugated estrogen (Premarin, 1964) were introduced therapeutically. Especially, the soluble types of adrenochrome compounds (Adona 1956, S-Adchnon, 1962) were devised and used widely in Japan. 2) Drugs concerning blood coagulation, thrombin, introduced in 1953, and hemocoagulase, a snake venom introduced in 1966, were used clinically. V.K. groups producing various coagulation factors were introduced as V.K1 (Phytonadione, 1962) and V.K2 (rnenatetrenone,1972), and they were admitted in "The Japanese Pharmacopoeia"editions 8 and 14, respectively). 3) Regarding antifibrinolytic drugs, Japanese researchers have made remarkable contributions. e-Aminocapronic acid (Ipsilon, 1962) and tranexamic acid (Transamin, 1965) were developed and used for various abnormal bleedings or hemorrhage associated with plasmin over-activation. tranexamic acid also proved to suppress inflammations of the throat such as tonsillitis, pharyngitis or laryngitis. 2. Antithrombotic drugs are also divided into three groups; anticoagulants, antiplatelet drugs and fibrinolytics.1) The anticoagulants used therapeutically by injection are heparins (Na-salt, 1951; Ca-salt, 1962) and low-molecular-weight heparins such as dalteparin (1992), parnaparin (1994) and reviparin (1999). The low molecule compounds are superior to the original heparins in reducing the risk of bleeding. As oral anticoagulants, coumarin derivatives, dicumarol (1950), ethylbiscoumacetate (1954), phenylindandione (1956) and warfarin (1962) are known. Warfarin potassium is the main drug for oral therapy of thromboembolism lately. Gabexate mesilate (1989) and nafamostat mesilate (1989) were developed in Japan and used for DIC and acute pancreatitis to inhibit protease enzymes. Argatroban is a unique antithrombin product developed by Japanese researchers in 1990, and is used for vascular or cerebral thrombosis. After noticing in 1968 that aspirin inhibits platelet aggregation and prevents myocardial infraction, projects for developing antiplatelet drugs were initiated worldwide. Ticlopidine, originally developed in France, was introduced in 1981 and prevailed widely in Japan for reducing the risk of thrombotic stroke. Aspirin itself was recognized by the FDA (USA) as an antithrombotic drug in 1988, and was also approved by Japanese authorities in 2000. PGE1 clathrate compounds have also been developed as antiplatelet drugs; alprostadil alfadex for injection (1979), and limaprost alfadex for oral use (1988). The PGI2 product, beraprost sodium, for oral use followed them in 1992. Other antiplatelet drugs with unique mechanisms explored in Japan: Ozagrel (1988), which inhibits TXA2 synthetase, cilostazol (1988), which inhibits cAMP phosphodiesterase, and sarpogrelate (1993), which blocks 5HT in platelets, are the notable drugs in this field. Ethyl icosapentate, from fish oil, is available for antiplatelet therapy. Concerning the fibrinolytic system, plasminogen activators are useful for thromboembolism. The streptokinase from bacterial origin developed in the USA and Europe was not introduced, and urokinase (1965) was the first plasminogen activator developed in Japan. Then tissue plasminogen activators (t-PA) tisokinase (cell culture, 1991), alteplase (genetical recombination, 1991), nateplase (genetical recombination, 1996), monteplase (1998) and pamiteplase (1998) were developed and approved for acute myocardial infarction. Nasaruplase (prourokinase, cell culture,1991) was also approved for the same indication. While the development of the hemostatic drugs ceased in the 1960s, avid project studies for antithrombotic drugs including fibrinolytics began in the 1980s and are progressing now towards new molecular targets. This may be due to the increasing tendency of cardiovascular thromboembolic diathesis in Japan. (The figures in parentheses are the years approved by the Japanese Ministry of Health, Labor and Welfare.)

Maternal septic shock and disseminated intravascular coagulation (DIC) following amniocentesis is a relatively rare condition, and its incidence is only 0.03 approximately 0.19%. Acute myocardial infarction (AMI) associated with DIC is also rare. We report here on a 40-year-old female patient who had septic shock and DIC that was complicated by AMI following amniocentesis. The possible mechanism of AMI in this patient may have been coronary artery thrombosis associated with DIC.

Reduced concentration of tissue factor pathway inhibitor is a risk factor for development of deep venous thrombosis, whereas elevated concentrations of tissue factor pathway inhibitor are observed in patients with acute myocardial infarction and disseminated intravascular coagulation. Presently, we studied the association between inflammation, endothelial cell perturbation, fibrin degradation and the concentration of tissue factor pathway inhibitor in patients suspected for acute deep venous thrombosis. We determined the tissue factor pathway inhibitor -33T/C polymorphism, free and total tissue factor pathway inhibitor, C-reactive protein, von Willebrand factor and D-Dimer in 160 consecutive patients admitted to hospital with a tentative diagnosis of acute deep venous thrombosis. Deep venous thrombosis was identified in 57 patients (18 distal and 39 proximal). The distribution of the tissue factor pathway inhibitor genotypes between patients with and without deep venous thrombosis showed a trend toward significant deviation (P = 0.08). The concentrations of free and total tissue factor pathway inhibitor, C-reactive protein, von Willebrand factor and D-Dimer were significantly higher in patients with deep venous thrombosis than in patients without deep venous thrombosis (P < 0.001 for all quantities). The significant relationship between free and total tissue factor pathway inhibitor and deep venous thrombosis persisted when adjusted for the tissue factor pathway inhibitor -33T/C polymorphism, C-reactive protein, von Willebrand Factor and potentially confounding clinical conditions (P < or = 0.004), but disappeared when adjusted for D-Dimer (P > or = 0.10). We conclude that patients suffering from acute deep venous thrombosis express significantly higher concentrations of tissue factor pathway inhibitor than patients without deep venous thrombosis. The significant relationship is not associated with the -33T/C polymorphism, inflammation or endothelial cell perturbation, but is most likely related to release of tissue factor pathway inhibitor from fibrin deposits.
