Changes in immunological parameters of polytrauma patients with use of terahertz electromagnetic waves in complex treatment

Introduction Improving the results of treatment and rehabilitation is essential for polytrauma patients. The aim of the study was to prove the effectiveness of terahertz electromagnetic waves (TEW) in polytrauma patients early after traumatic event to improve immune parameters. Material and methods The study included 20 polytrauma patients who were divided into two groups. Patients of the treatment group (n = 10) received TEW early after traumatic event in addition to standard treatment using the damage control approach. Control patients (n = 10) received no TEW therapy in the complex of therapeutic measures. Immunological studies were performed during treatment. The effectiveness of rehabilitation was assessed at a long term using an evaluation scale. Results The mean rehabilitation score was significantly higher in the treatment group compared to the controls. The treatment group showed significantly higher production of TNFα and IL-2, spontaneous production of IFNγ by lymphocytes, phagocyte activity (NBT-test) and absorption activity of monocytes after the use of TEW in comparison with controls. An increased level of IgG and IgM was also noted in patients of the treatment group. Discussion The findings showed that the use of TEW in polytrauma patients early after traumatic event resulted in the increase in cytotoxic activity of lymphocytes and phagocytic cells. The immunostimulating effect of TEW was also achieved through boosting humoral immunity. Conclusion The TEW used early after traumatic event in polytrauma patients resulted in strengthening of the immune system which contributed to more effective rehabilitation.
