Antithrombotic effect of taurine in healthy Japanese people may be related to an increased endogenous thrombolytic activity

IntroductionPrevention of arterial thrombotic diseases has high priority in developed countries. Taurine (2-aminomethylsulfonic acid), which is rich in sea foods, showed antithrombotic effect in animal models of thrombosis. The present study aimed to investigate such effect in healthy human volunteers.Methods and ResultsIn 101 healthy Japanese people the overall thrombotic status was accessed from non-anticoagulated blood sample by the Global Thrombosis Test (GTT). There was no significant correlation between taurine concentration in urine samples and GTT-Occlusion Times (OT; mainly reactivity of platelets). In contrast, a significant inverse correlation was demonstrated between urine taurine concentrations and GTT-Lysis Times (LT; showing spontaneous thrombolytic activity).ConclusionsOur findings suggest that taurine enhances endogenous thrombolytic activity which could be a mechanism of the earlier observed cardioprotective and antithrombotic effect.
