Lipopolysaccharide Binding Protein and Development of Infectious Events in Cirrhotic Patients

Official Title: “Association of Serum Levels of Lipopolysaccharide Binding Protein (LBP) With the Evolution of Pro- and Anti-Inflammatory Cytokines, and the Development of Severe Infectious Events in Cirrhotic Patients”

The purpose of this study is to determine whether plasma levels of lipopolysaccharide binding protein (LBP) are correlated with PBMN pro- and anti-inflammatory cytokine secretion, as well as with the development of severe infectious events in cirrhotic patients with ascites. As a secondary purpose, the study will evaluate the effect of a prophylactic administration of ciprofloxacin on LBP, cytokines and infections in the same patients.
