Serum lipopolysaccharide binding protein levels predict severity of lung injury and mortality in patients with severe sepsis.

<h4>Background</h4>There is a need for biomarkers insuring identification of septic patients at high-risk for death. We performed a prospective, multicenter, observational study to investigate the time-course of lipopolysaccharide binding protein (LBP) serum levels in patients with sever...
