Abstract

 

Traumatic brain injury (TBI) is a significant problem in modern clinical medicine that has both medical and social importance. Analysis of hemostatic changes is a very important aspect of clinical course of TBI and should be paid special attention on it. This analysis is necessary to make prognosis for the treatment outcomes taking into account associations with genetic factors.

The aim of research was to analyze hemostatic profile changes in patients with TBI with regard to the genotype of -675 4G/5G polymorphism of plasminogen activator inhibitor-1 gene (РАІ-1).

Methods and materials. The research was based on the investigation results of 200 patients with isolated TBI, who were undergoing in-patient treatment at the neurosurgery department at Sumy Regional Clinical Hospital in 2011–2013, and 95 apparently healthy individuals of the control group.

The following change cycling was confirmed during the study: a tendency to hypercoagulability on the 1st day transforming into a state of being incapable of coagulation on the 3rd day. On the 7 day hypercoagulability signs dominated and by the 14 day the laboratory findings had gradually become normal.

Conclusions. According to the analysis of routine hemostatic profile parameters (activated partial thromboplastin time, prothrombin index, platelet count, plasma tolerance to heparin, activated recalcification time, euglobulin clot lysis assay, plasma fibrinogen level) we concluded that there is no association between the studied parameters and the genotypes of the -675 4G/5G polymorphism in the PAI-1 gene in patients with TBI and controls. Our study confirms the necessity of further monitoring of fibrinolytic system, since routine laboratory tests of haemostasis are not always informative as for the fibrinolytic disorders in patients with TBI.
