Factor XIII in major burns coagulation

Background: In the days following a burn injury, major burn patients (MBP) present a multifactorial coagulation disorder known as acute burn-induced coagulopathy. Several studies have investigated coagulation in MBPs; however, Factor XIII (FXIII), which converts fibrin monomers into a stable clot and promotes wound healing, has not yet been studied. Objective: To determine the kinetics of FXIII and other coagulation factors and cofactors in MBPs in order to clarify coagulopathy in these patients and its potential relationship with surgical bleeding. Methods: Prospective observational pilot study of the kinetics of FXIII and other coagulation factors and cofactors in MBPs during the first 30 days of burn injury. Results: FXIII levels show a significant decline of 75.10% in the interval between the burn injury and surgery, and a decline of 87.70% in the 24 h following surgery. Patients undergo surgery with a median antigenic FXIII of 32%. Plasma levels of most factors decrease significantly 24 h after the burn injury. Conclusion: MBPs experience a significant decrease in plasma levels of FXIII from the time of admission up to 24 h after surgery. Abnormally low levels were observed at the time of surgery that could not be detected by other coagulation tests. The decrease in most factors at 24 h seems to be associated with dilution due to intensive fluid resuscitation.
