Various factors orchestrate early immune reactions, such as the amount of affected body surface area, burn depth and cause, inhalation injury, patient age, and chronic medical conditions 9. Though inflammation is inherent and indispensable for normal wound healing 7, burn injuries can induce a state of distorted inflammatory response which can persist up to several years 8 and which can ultimately lead to host tissue damage and organ dysfunction. Later, the milieu is shifted towards an anti-inflammatory response syndrome (AIRS), where the immunosuppressant mediators TGFβ1, and IL-10 prevail 6. The early systemic inflammatory response syndrome (SIRS) is characterized by pro-inflammatory cytokines, such as interleukin 6 (IL-6), IL-8, and tumor necrosis factor alpha (TNFα) and usually lasts for several days 5, 6. Morbidity and mortality can be increased up to 10 years after the initial insult 3.īurn trauma elicits a unique systemic stress response characterized by increased metabolism and inflammation 4. In spite of the development of new therapeutic approaches, burn injuries are still associated with a high mortality rate, most commonly resulting from multiple organ failure, sepsis, and respiratory complications 2. The respective cause and burn degree further dictate clinical management, such as surgical intervention and moist rewarming following heat- and cold-induced injuries, respectively.

Targeting exacerbated neutrophil activation might represent a new therapeutic option for severe cases of burn injury.īurn injury is an umbrella term for a trauma, most commonly affecting the skin or lung, caused by a variety of external challenges, such as thermal extremes, deleterious radiation, alkaline and acidic chemicals, or excessive friction 1. Taken together, our data suggest a role for neutrophil activation and NETosis in burn injuries and burn injury progression. Accordingly, CitH3 and NE were elevated in cases with higher abbreviated burn severity indices (ABSI). Though neutrophil-derived factors did not predict mortality, patients suffering from 3rd degree burn injuries displayed increased CitH3 and NE levels. Leukocyte and neutrophil counts were significantly increased on admission day and day 1, while relative lymphocytes were decreased in the first 7 days post burn trauma. Serum levels of NE, MPO, CitH3, and C3a were remarkably elevated in burn victims compared to healthy controls.

Lastly, we analyzed the association of neutrophil-derived factors with clinical severity scoring systems. In addition, leukocyte, platelet, neutrophil, and lymphocyte counts were assessed. Furthermore, the potential association with mortality, degree of burn injury, and inhalation trauma was evaluated. Serum levels of neutrophil elastase (NE), myeloperoxidase (MPO), citrullinated histone H3 (CitH3), and complement factor C3a were quantified in burn victims over 4 weeks post injury. Though neutrophils represent crucial players in the burn-induced immunological events, the dynamic secretion pattern and systemic levels of neutrophil-derived factors have not been investigated in detail so far. Burn injuries elicit a unique and dynamic stress response which can lead to burn injury progression.
