Antibiotic prophylaxis in patients with cirrhosis: Current evidence for clinical practice.

Patients with cirrhosis show an increased susceptibility to infection due to disease-related immune-dysfunction. Bacterial infection therefore represents a common, often detrimental event in patients with advanced liver disease, since it can worsen portal hypertension and impair the function of hepatic and extra-hepatic organs. Among pharmacological strategies to prevent infection, antibiotic prophylaxis remains the first-choice, especially in high-risk groups, such as patients with acute variceal bleeding, low ascitic fluid proteins, and prior episodes of spontaneous bacterial peritonitis.

Post-load insulin resistance does not predict virological response to treatment of chronic hepatitis C patients without the metabolic syndrome.

Background And Aim: The role of insulin resistance in predicting virological response to therapy of chronic hepatitis C is debated. We assessed the association between basal (defined as homeostasis model assessment of insulin resistance (HOMA-IR)>2) and post-load insulin resistance (as oral glucose insulin sensitivity index<9.8 mg/kg/min) with the rapid and sustained virological responses in chronic hepatitis C.

Radiofrequency ablation of hepatocellular carcinoma in cirrhotic patients.

Background/aims: Radiofrequency ablation is useful for local destruction of primary and secondary hepatic tumors. However there is little information about long-term outcome for patients with hepatocellular carcinoma and cirrhosis. The aims of this study included the analysis of efficacy in local control of tumors, patterns of recurrence and survival rate related to severity of cirrhosis and tumor features.
