Abstract
- The predictive value of circulating free DNA/neutrophil extracellular traps (cf-DNA/NETs) has recently been shown in patients with major trauma for sepsis, multiple organ failure, and mortality. Here we report on the predictive potential of cf-DNA/NETs for mortality in patients with severe burn injury. In a prospective study 32 patients with severe burn injury were included. Blood samples were sequentially obtained on day 1, 3, 5, and 7 after admission. cf-DNA/NETs was directly quantified from plasma by means of rapid fluorescence assay. Time kinetics of cf-DNA/NETs were correlated with clinical data, C-reactive protein (CRP), procalcitonin (PCT), and interleukin (IL)-6. Furthermore sensitivity, specificity, and positive and negative predictive value, as well as receiver operation characteristic (ROC) curves were calculated. Seven patients died within the first month after burn injury. cf-DNA/NETs values from these patients were significantly increased already on day 1 and 3 after admission compared with patients who survived ( p < 0.01). In contrast, PCT levels of nonsurvivors were significantly elevated on day 3 and 5 ( p < 0.01), while CRP and IL-6 did not show any significant difference between survivors and nonsurvivors. At a cutoff of 255 ng/ml, cf-DNA/NETs had sensitivity of 0.8 and specificity of 0.74. ROC revealed largest areas under the curve (AUC) for cf-DNA/NETs on day 1 (0.851) and 3 (0.883) after admission. For all values between day 1 and 7, AUC was 0.815. cf-DNA/NETs seems to be a rapid, valuable marker for prediction of mortality in burn patients. A larger confirmation trial ought to be carried out.
