Resistin forms a network with inflammatory cytokines and is associated with prognosis in major burns

Background: In current intensive care treatment, some patients with severe burns cannot be saved due to progressive organ failure. Further investigation of the pathogenesis of severe burns is needed to improve the mortality rate. In burns, inflammatory cytokines form a network that leads to an inflammatory response. Adipocytes secrete physiologically active substances (adipokines). The roles of adipokines have not been completely clarified in burn patients. This study aimed to determine the relation between serial changes of adipokines and clinical course in severely burned patients.Methods: This was a single-center, retrospective, observational study. Patients' blood samples were collected on the day of injury and around 1 week later. Adipokines (adipo-nectin, angiotensinogen, chemerin, CXCL-12/SDF-1, leptin, resistin, vaspin, visfatin), var-ious inflammatory cytokines, syndecan-1 and C1 esterase inhibitor were measured.Results: Thirty-eight patients were included. Resistin levels were significantly higher in the non-survivors versus survivors on Day 1 after burn injury. Hierarchical clustering analysis showed common clusters on Day 1 and at 1 Week after burn injury (resistin, IL-6, IL-8, IL10 and MCP-1). The correlation coefficient of resistin to SOFA score at 1 Week was significant. Logistic regression analysis showed a significant relation of resistin levels on Day 1 with prognosis; the area under the ROC curve for resistin was 0.801.Conclusions: In the acute phase of burns, resistin was associated with other pro -in-flammatory cytokines and was related to the severity and prognosis of major burns.(c) 2021 Elsevier Ltd and ISBI.

Automated summary

The study aimed to investigate the relationship between changes in adipokines and the clinical course of severely burned patients. The results showed that resistin, an adipokine, was associated with other pro-inflammatory cytokines and was related to the severity and prognosis of major burns.
