Increased hemostatic molecular markers in patients undergoing anticoagulant therapy.

We evaluated several molecular markers of hemostasis in 92 patients with hypercoagulable states treated with anticoagulant therapy. In all patients, the average values of the international normalized ratio (INR) were 1.70 +/- 0.

Diagnosis of disseminated intravascular coagulation by hemostatic molecular markers.

In the present study, the positive rate of thrombin-antithrombin complex (TAT), plasmin-plasmin inhibitor complex (PPIC), soluble fibrin monomer (sFM), and D-dimer for the diagnosis of disseminated intravascular coagulation (DIC) was evaluated. The study comprised 307 patients with DIC, 123 with pre-DIC, and 121 with non-DIC. Plasma levels of TAT, PPIC, sFM, and D-dimer were significantly higher in DIC and pre-DIC patients than in non-DIC patients.

Hemostatic abnormalities in patients with thrombotic complications on maintenance hemodialysis.

Before hemodialysis (HD), plasma levels of tissue factor (TF), free-TF pathway inhibitor (TFPI) and thrombomodulin (TM) were significantly higher in patients with HD than in healthy volunteers. Plasma levels of (T-F) TFPI and plasmin plasmin inhibitor complex (PPIC) were significantly higher in patients with HD than in healthy volunteers. During HD, plasma levels of TF and (T-F) TFPI were not significantly increased, but plasma levels of total TFPI and free TFPI at 1 hour after and at the end of HD were significantly increased, compared with levels before start of HD.

Aberrations of the tissue factor pathway in patients positive for lupus anticoagulant.

To evaluate the relationship between the tissue factor (TF) pathway and lupus anticoagulant (LA), in the present study, we measured the plasma levels of TF antigen and TF pathway inhibitor (TFPI) antigen in patients positive for LA. Plasma TF and TFPI levels in LA-positive patients were significantly higher than levels in healthy volunteers (p < 0.01).

Hemostatic markers in Japanese patients undergoing anticoagulant therapy under thrombo-test monitoring.

The objective of this study was to evaluate several molecular markers of hemostasis in 84 patients with hypercoagulable state, treated with warfarin under thrombo-test (TT) monitoring; TT was expressed as percent of control (TT%). In all patients, the average values of international normalized ratio (INR) of prothrombin time (PT;PT-INR) was 1.68+/-0.
