title: Serum lipopolysaccharide-binding protein prediction of severe bacterial infection in cirrhotic patients with ascites.
abstract: Serum lipopolysaccharide-binding protein is increased in a subset of non-infected ascitic cirrhotic patients, a finding previously related to bacterial passage from the gut to the circulation without overt infection. We prospectively analysed the risk factors associated with a first episode of severe bacterial infection in 84 ascitic cirrhotics, followed up for a median of 46 weeks. The cumulative probability of such infection in patients with raised and normal lipopolysaccharide-binding protein was 32.4% and 8.0% (p=0.004), respectively. Increased lipopolysaccharide-binding protein was the only factor independently associated with severe bacterial infection in a multivariate analysis (relative risk 4.49, 95% CI 1.42-14.1). Monitoring of serum lipopolysaccharide-binding protein could, therefore, help to target cirrhotic patients with ascites for antibiotic prophylaxis.
