To study factor VII (F VII) hyperactivity in chronic dialysis patients, we measured the plasma levels of F VII activity (F VII c) and antigen (F VII Ag), prothrombin activation fragments 1 + 2 (F1 + 2), thrombin-antithrombin III complexes (TAT), and thrombomodulin in 28 patients on hemodialysis. Marked elevation of F VII c was found in long-term dialysis patients (185 +/- 30%). This hyperactivity was accompanied by both elevation of the F VII Ag level (153 +/- 28%) and enhanced activation of F VII zymogen, expressed as the F VII c/F VII Ag ratio (1.23 +/- 0.23), but pseudocholinesterase activity was decreased. The 6 patients with ischemic heart disease had slightly higher F VII c (200 +/- 25%) than those without ischemic heart disease (181 +/- 30%), although the difference was not significant. Increased F VII c was accompanied by factor Xa hyperactivity (a high plasma F1 + 2 level) in the long-term dialysis patients, but there was no significant elevation of plasma TAT levels when compared with controls matched for age, sex, and the presence or absence of diabetes mellitus. Plasma TAT levels were significantly correlated with plasma thrombomodulin levels, suggesting that thrombin generation in blood as a result of hemodialysis could induce systemic endothelial cell injury.

DX-9065a is a direct and selective factor Xa inhibitor. We evaluated the usefulness of DX-9065a in anticoagulating specimens for routine laboratory tests. Results using blood anticoagulated with DX9065a corresponded well with results with blood treated with ethylendiamine tetraacetic acid (EDTA) in the complete blood count (CBC), including white blood cell (WBC) differential count and morphology of blood cells. Clinical chemistry results from DX-9065a-treated samples were similar to results obtained with serum specimens except for leucine aminopeptidase (LAP) and cholinesterase (Ch-E). Thus, DX-9065a may be a useful universal anticoagulant for laboratory medicine.
