Introduction. Combat injuries, including gunshot, shrapnel, and mine-explosive wounds, affect a significant number of soldiers in modern warfare. Notably, most of these injuries involve damage to the soft tissues of the extremities. Surgeons have expressed concerns regarding the unsatisfactory treatment outcomes in this group of combatants, attributing one of the primary challenges to the limited understanding of immune dysfunction pathogenesis in military trauma cases. This study aims to address this gap by examining immune system dysfunctions in combat-related injuries.
The objective of this study is to thoroughly analyze and synthesize the key stages of immune dysfunction occurring over extended periods post-combat trauma, including the subsequent development of traumatic disease and various wound complications.
Materials and Methods. The rising prevalence of combat trauma among soldiers has intensified interest in studying this issue, prompting surgeons and traumatologists to address its various medical aspects comprehensively. The literature search focused on recent publications, allowing for a targeted analysis of the immunological aspects relevant to military medical traumatology.
Results. In the initial stages of severe or combined injuries affecting various tissues—such as tubular bones, joints, blood vessels, and peripheral nerves—systemic inflammatory response syndrome (SIRS) commonly occurs. This stage is marked by an intense activation of innate antibacterial and immune-protective responses, leading to a significant increase in inflammation. This initial response is soon replaced by a prolonged phase known as compensatory anti-inflammatory response syndrome. During this period, immune-protective responses sharply decrease, certain immunocompetent cells become inhibited, and lymphopenia develops. This phase is often accompanied by infectious contamination of wounds with pathogenic and opportunistic microorganisms, resulting in both local purulent-necrotic processes and potentially severe systemic complications, such as septic shock, sepsis, multiple organ failure, and others. The final stage, known as persistent inflammatory, immunosuppressive, catabolic syndrome, is characterized by the chronic progression of traumatic disease, accompanied by ongoing immune system dysfunction in combatants.
Conclusion. In the early period of traumatic injury, the wounded experience sharp inflammatory processes and activation of immune defense mechanisms. At subsequent stages, severe disruptions in the functioning of the immune system, damage to internal organs, and the development of catabolic syndrome are recorded. These changes, especially those resulted from exposure to chronic combat stress preceding the injury, aggravate the processes of infectious decontamination of wounds, regeneration of damaged tissues, and the general process of combatant rehabilitation.
