Fecal calprotectin is a useful screening parameter for hepatic encephalopathy and spontaneous bacterial peritonitis in cirrhosis

Objective: Bacterial translocation, causing intestinal inflammation, is one of the key mechanisms in the pathogenesis of hepatic encephalopathy (HE) and spontaneous bacterial peritonitis (SBP) The presence of fecal calprotectin quantitatively relates to intestinal neutrophil migration and is therefore considered as a marker of intestinal inflammation. We aimed to assess the role of fecal calprotectin concentrations (FCCs) in diagnosing the onset and severity of HE and SBP. Methods: Sixty-one cirrhotics were prospectively included. Forty-two subjects served as controls. Several complications of cirrhosis were diagnosed by reference methods. Stool samples were collected for measuring FCCs. Patients revealing other causes of abnormal calprotectin results, e.g. gastrointestinal bleeding or inflammatory bowel disease were excluded. Multivariate analysis of cirrhosis-associated complications and their relation to FCCs was performed. Results: Fecal calprotectin concentrations were higher in cirrhotics compared with controls (P
