However, the common usage of antibiotics has led to the rise of antimicrobial drug-resistant pathogens, with an incidence of multi-drug–resistant infection between 10%–17%, which imposes a significant burden on the healthcare system. Antibiotics have been used both parenterally and locally, although topical use is emphasized, as systemic antibiotics may have poor penetrance to the site of infection in sufficiently active concentrations to eliminate microbial pathogens. Traditional therapy for burns has revolved around debridement of devitalized tissue, saline irrigation, and application of antimicrobial agents to reduce the bacterial load in the wound. This leaves patients highly susceptible to infection, which further propagates the immune compromise. Burn injury causes loss of skin, mucosal, and endothelial integrity, as well as up-regulation and eventual dysfunction of the immune system. ![]() A secondary infection can exacerbate immune suppression and dysfunction, as summarized in Figure 1.īurn-induced immune dysfunction. This is thought to leave patients at high risk for infection of the wound, lung, and urinary tract, as well as bacteremia and overwhelming sepsis. After the initial trauma, major findings include the depletion of blood lymphocytes, cytokine suppression, and decreased ability of cells to proliferate on stimulation. This breakdown in the traditional immune defense systems is compounded by a state of relative immune compromise that is observed in burn patients who survive. Burn patients also suffer from gut mucosal loss and endothelial integrity, which permits bacterial translocation and further bacterial exposure. Thus, disruption of this barrier through large surface area burns leaves the patient at risk for immune dysfunction. Indeed, local skin flora impacts the regulation and balance of the leukocyte types in the body. The skin provides an obvious physical barrier as well as a competent immune system. The skin and native microbiota are the first line of defense against environmental pathogens in the body. The burn wound is the most likely portal of entry for pathogens, although greater susceptibility to invasion from the lung, abdomen, and urinary tract have been demonstrated. However, the primary cause of death in all age groups remains infection and subsequent sepsis. Survival rates have improved because of innovation in fluid management, wound care, early nutrition, and infection control. We discuss novel therapeutics for the treatment of burn infection: Probiotics and therapeutic microorganisms, immune modulators, tailored monoclonal antibodies, and extracellular vesicles and proteins.Ĭonclusions: The treatment strategies discussed employ manipulation of structure and function in host immune cells and pathogen virulence for improved outcomes in burn infection.īurn trauma is a common cause of morbidity and death worldwide, with nearly 500,000 patients per year receiving treatment. Results: Topical antimicrobial drugs continue to be standard of care for burn wound injuries, but personalized and molecular treatments that rely on immune manipulation of the host show great promise. Methods: Between February 15 and March 15, 2020, a search of Pubmed and was performed using search terms such as “burn immunotherapy,” “therapeutic microorganisms in burn,” “burn infection clinical trials,” and applicable variations. With resistance to traditional antibiosis looming as a serious threat to patient outcome, advancement in the treatment of burn infections is imperative. Patients are susceptible to overwhelming infection secondary to both the physical breakdown of the skin and mucosal barrier and the immune dysfunction that accompanies the inflammatory response to a major burn. ![]() ![]() Data CDs are fully ISO compliant with Joliet extension.Background: Burn injury continues to be a significant cause of morbidity and death, with infectious complications being the primary cause of death.Supports burning of WAV, MP3, WMA, AU, AIFF, RA, OGG, FLAC, AAC, and a number of other audio file formats. ![]() Audio CDs are recorded with direct digital recording (so perfect audio quality is maintained).Can seamlessly burn audio CDs with no pause between tracks.Express Burn Plus can burn ISO compliant data DVDs and (DVD-R, DVD-RW, DVD+R, DVD+RW).Records CD Recordable (CDR) and CD Re-recordable (CDRW) discs.Mp3 CDs (larger capacity alternative to audio cds).Express Burn is also the fastest CD/DVD writing program in the world using proprietary optimizing systems.
