The Role of DAMPS in Burns and Hemorrhagic Shock Immune Response: Pathophysiology and Clinical Issues. Review.

Int J Mol Sci 2021 Jun 29;22(13). Epub 2021 Jun 29.

Trauma Team, Acute Care Surgery and Trauma Unit, Careggi University Hospital, Largo A. Brambilla 3, 50134 Florence, Italy.

Severe or major burns induce a pathophysiological, immune, and inflammatory response that can persist for a long time and affect morbidity and mortality. Severe burns are followed by a "hypermetabolic response", an inflammatory process that can be extensive and become uncontrolled, leading to a generalized catabolic state and delayed healing. Catabolism causes the upregulation of inflammatory cells and innate immune markers in various organs, which may lead to multiorgan failure and death. Read More
