Assessment of the Predictive Value of Fecal Calprotectin for the Outcome of Severe Alcoholic Hepatitis
- Conditions
- Severe Alcoholic Hepatitis
- Interventions
- Biological: fecal calprotectin concentrationBiological: blood collection
- Registration Number
- NCT02808663
- Lead Sponsor
- CHU de Reims
- Brief Summary
Severe alcoholic hepatitis, defined by a "Maddrey discriminant function" above 32, is associated with significant short-term mortality. In patients with liver disease, studies have shown alterations of intestinal bacterial flora and an increase in intestinal permeability leading to bacterial translocation across the intestinal barrier. The mechanism involved may be an activation of intestinal macrophages with a local release of cytokines like interleukin-8 (IL-8).
Calprotectin is a protein present in large amounts in the cytosol of neutrophils. Its presence in feces is related to neutrophil migration in intestinal lumen. Thus, fecal calprotectin may be used as a marker of intestinal inflammation. There is evidence that fecal calprotectin levels are increased in cirrhotic patients dependent on the severity of the disease. The predictive value of fecal calprotectin for the outcome of severe alcoholic hepatitis has never been evaluated.
The main objective of this study was to determine if the initial level of fecal calprotectin and its variation after 7 days had a predictive value for the outcome of severe alcoholic hepatitis. Secondary objectives were to determine if fecal calprotectin concentration was correlated with blood concentration of Lipopolysaccharide (LPS) binding protein and predictive of infections.
