Clinical Trial Summary

Current study evaluates the relationship between cell immunity, biochemical and genetic markers in patients with sepsis in order to develop algorithm for predicting the course and outcome of severe bacterial infections.

Description:

- To study the state of the immune system in patients with sepsis: the content of blood monocyte subpopulations (classical, intermediate and non-classical monocytes), HLA-DR expression on monocytes, CD64 expression on neutrophils, spontaneous and stimulated production of reactive oxygen species by blood neutrophils etc.; - To study biochemical blood parameters and genetic polymorphism of immune response genes; - To evaluate the relationship between genetic features of the patient's immune system, biochemical blood parameters, immune system cells and the severity of the pathological process. - To develop an algorithm to prevent the development of sepsis in children.
