Outline of Final Research Achievements

Heparin is frequently used for preventing thrombosis. Heparin-induced thrombocytopenia (HIT), an adverse effect of heparin, is potentially lethal. So, an early diagnosis is needed to avoid iatrogenic worsening. In this study, we examined potential usefulness of total thrombus-formation analysis system (T-TAS) in HIT diagnosis. Platelet-rich thrombus formation in T-TAS is impaired when heparin is mixed with whole blood from healthy volunteers. However, platelet-rich thrombus formation in T-TAS is paradoxically augmented if heparin is mixed with whole blood from HIT patients. These findings indicate that T-TAS may be potentially useful in distinguishing patients with HIT from those without HIT. Further studies are needed to evaluate its clinical usefulness.
