Pathomorphology of inflammatory response following traumatic brain injury, serum values of interleukins, and gene polymorphisms
Abstrakt
Our present study was aimed to investigate time-profile kinetics of interleukins, vascular endothelial growth factor (VEGF) in acute inflammatory response following traumatic brain injury, and the influence of activated microglial cells in patients who developed severe space occupying lesion (SOL) of secondary traumatic brain injury. Interleukins IL-6, monocyte chemo attractant protein (MCP-1), and VEGF had a significant different time-profile kinetics (p<0.05) in patient with, and without expansive traumatic brain contusions (SOL).
The serum VEGF was significantly higher in trauma patients with uncomplicated brain contusions, and lower in patients with SOL. The patients with septic complications developed the sudden increase of TNF alpha and IL-8 within the first 72 hours.
Our data suggested PSGL and CD68 immunopositivity of microglial cells in both focal and diffuse TBI, predominantly in perivascular space correlated with telolysosome formation in cytoplasma. Polymorphism of PAI-1, MTHFR, eNOS, VEGF, and Apo E genes in TBI were in patients with SOL were bound to show up leucocyte plugging in capillaries.
