Endothelial dysfunction in burn injury

Year: 2019, volume 15 Issue: №2 Pages: 377-379
Heading: Physiology and Pathophysiology Article type: Original article
Authors: Morrison V.V., Bozhedomov A.Yu., Morrison A.V.
Organization: Russian State Medical University, Saratov State Medical University
Summary:

Objective: to estimate the level of markers of endothelial dysfunction in burn injury of various severities. Material and Methods. 57 patients were included in the study. The level of vascular endothelial growth factor (VEGF), endothe-lin, nitric oxide metabolites (NO), and the amount of circulating desquamated endothelial cells were determined in the dynamics of burn injury development. Results. In burn injury there was an increased amount of endothelial dysfunction markers in blood, which is highly expressed on the 7-15th day. Moreover on the 7th day in case of severe and extremely severe burn injury the level of VEGF was increased over 50 times while the amount of endothelin, nitric oxide metabolites and circulating desquamated endothelial cells becomes higher in 3–5 times. Conclusion. The research outcomes have proved the damage of endothelial lining in burn injury.

Systemic inflammatory response and cytokine profile at burn injury in dynamics

Year: 2017, volume 13 Issue: №2 Pages: 229-232
Heading: Physiology and Pathophysiology Article type: Original article
Authors: Morrison V.V., Bozhedomov A.Yu., Simonyan M.A., Morrison A.V.
Organization: Leningrad Regional Clinical Hospital, Saratov State Medical University
Summary:

The aim of the article is to study the dynamics of indices of systemic inflammation in correlation with the following factors: the outcome of the disease, disturbances in proinflammatory cytokines rate and vascular endothelial dysfunction markers rate at burn injury in dynamics. Material and Methods. 152 patients with burn injuries over 30 units by Frank's index were under the study. The research on the level of interleukins, endothelial vessels growth factor, macrophage chemotactic protein, level of endothelin and C-reactive protein was performed with quantitative immuno-enzymatic detection. The amount of circulating of desquamated endothelial cells was accounted by phase-contrast microscopy. Results. Proinflammatory cytokines rate and vascular endothelial dysfunction markers rate significantly increase reaching their maximum indices to the 7-15th day of burn injury and indicating the expressiveness of systemic inflammatory response syndrome. Conclusion. The received data have become important in the determination of increased number of criteria of systemic inflammatory response syndrome depending on the outcomes of the burn injury and endothelial dysfunction development.

Procalcitonin as a diagnostic test for thermal injury

Year: 2014, volume 10 Issue: №1 Pages: 61-64
Heading: Physiology and Pathophysiology Article type: Original article
Authors: Morrison V.V., Bozhedomov A.J.
Organization: Saratov State Medical University
Summary:

Purpose: to determine the diagnostic value of procalcitonin in blood serum with probable development of multiple-organ-failure syndrome in thermal injury. Material and Methods. Procalcitonin test has been performed on the 1st, 3d, 7th, 15th and 30th days after the thermal injury. The expression of systemic inflammatory response syndrome (SIRS), leukocytic intoxication index (Lll) calculated according to Ya.Ya. Kalf-Kalif, levels of C-reactive protein, MCP-1, IL-6, VEGF, endothelin, and a number of circulating endothelial cells have been determined. Results. The increased level of procalcitonin (>0,5 ng/ml) in thermal injury has been observed in 42,7% of recovered patients and in 71,3% of dead patients. Conclusion. It has been found out that procalcitonin test in thermal injury may be used as an early marker for patients liable to develop polyorgan insufficiency syndrome.

Cytoprotective effect of cytoflavinum at treatment of thermal injury of various severity level

Year: 2012, volume 8 Issue: №1 Pages: 038-042
Heading: Physiology and Pathophysiology Article type: Original article
Authors: Bozhedomov A.J., Morrison V.V., Shulaeva N.M., Nikitina V.V., Ivanenko I.L.
Organization: Saratov State Medical University, Saratov City Clinical Hospital №7
Summary:

The purpose of research was studying of cytoprotective effect of cytoflavinum at a thermal trauma of different severity level. Materials and methods. 169 patients with thermal burns with a favorable outcome and gravity of a thermal trauma from 30 to 170 points on Franc were under research. 28 patients took standard dosage of cytoflavinum while complex therapy. Results. Patients with thermal trauma more than 60 points on Franc took Cytoflavinumuse and demonstrated decrease in intensity of system inflammatory response syndrome (SIRS), reduction of band neutrophils portion, lowering of erythrocyte number, smaller activation ofthrombocytopoiesis, dicrease of concentration of vascular endothelial growth factor. Positive effect was not revealed in group of patients with thermal trauma less than 60 points who received cytoflavinum. Conclusion. Use of cytoflavinum was the most effective at thermal trauma gravity more than 60 points on Franc

Diagnostic value of markers of vascular endothe-lial injury in thermal traumas

Year: 2011, volume 7 Issue: №3 Pages: 629-632
Heading: Clinical Laboratory Diagnostics Article type: Original article
Authors: Morrison V. V., Bozhedomov A. Yu., Zakharova N. В., Podgornova A. V.
Organization: Saratov City Clinical Hospital №7, Saratov State Medical University
Summary:

The research goal is to study the composition of biological vascular endothelial injury markers in dynamic development of burn disease. Materials and methods: the investigation included 32 patients with thermal burns. The markers of vascular endothelial growth factor (VEGF), monocyte chemotactic protein-1 (MCP-1) and the number of circulating endothelial cells (CECs) were observed. Results: it was revealed that levels of VEGF, MCP-1 and CECs were significantly increased in patients with thermal traumas. Conclusion: VEGF and MCP-1 were proved to be early and prominent vascular endothelial injury markers in burn disease
