THE SIGNIFICANCE OF PLATELET-DERIVED GROWTH FACTOR CONCENTRATIONS IN ENDOTHELIOTROPIC NATURAL FOCI INFECTIONS

In recent years, the clinical symptomatology of Astrakhan spotted fever and coxiellosis has worsened. The pathogenesis of these two natural focal, endothelium-dependent infections is rather complicated, multifactorial and not properly studied. The current clinical symptomatology is characterized by severe intoxication syndrome, frequently signs of multiple organ failure, development of hemocoagulation and vascular complications [3, 4, 5]. To date, no early markers of endothelial vascular damage have been proposed for use in practical health care, which enable accurately assessing the severity degree and predicting the further course of the rickettsiae and coxiellosis. Platelet-derived growth factor (PDGF), which is widely used in the diagnosis and prognosis of cardiovascular diseases, various injuries and diabetes mellitus, may become such a marker.
