ABSTRACT
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. In DIC patients, the positive rate of sFM was high and that of
D-dimer was low; the positive rate of PPIC was higher in patients with hematopoietic
malignancy than in those without this disease. In pre-DIC patients, the positive rate
of all markers was low (<0.16), and the positive rate of PPIC was relatively high.
In non-DIC patients, the positive rate of all hemostatic markers was low (<0.16),
that of sFM being the lowest. Scoring the positive rate of TAT, PPIC, and sFM disclosed
the following results: 72% of DIC patients had three or more points, 17.6% of pre-DIC
patients had three or more points, and almost all (96.6%) non-DIC patients had two
or less points. Scoring the positive rate of TAT, PPIC, and D-dimer disclosed the
following results: 52.9% of DIC patients and 27.4% of pre-DIC patients had three or
more points and almost all (96.7%) non-DIC patients had 2 or less points. These data
suggest that the combination of TAT, PPIC, and sFM is useful for making the diagnosis
of DIC.
