• Can Blood Levels of Ammonia Predict Risk and Frequency of Hepatic Encephalopathy in Patients With Cirrhosis?

Can Blood Levels of Ammonia Predict Risk and Frequency of Hepatic Encephalopathy in Patients With Cirrhosis?

Fasting levels of ammonia (NH3) in blood identify patients at risk for complications of overt hepatic encephalopathy (HE), researchers report in the June issue of Clinical Gastroenterology and Hepatology. Patients with HE might benefit from NH3-lowering therapy. Humans have no repository for excess dietary nitrogen, so we convert excess dietary

Can we Promote Liver Regeneration in Patients with Decompensated Cirrhosis?

The combination of granulocyte colony-stimulating factor (G-CSF) and a long-acting form of erythropoietin increases survival of patients with decompensated cirrhosis, researchers report in the June issue of Gastroenterology. The growth factor combination also improved liver function and reduced risk for septic shock within 1 y of treatment. Decompensation in patients

Does FibroScan Accurately Assess Liver Fibrosis?

Vibration-controlled transient elastography (VCTE) with FibroScan can provide an accurate assessment of liver fibrosis in patients with chronic viral hepatitis, but operator-related and patient-related factors affect measurements, report 2 articles published in the April issue of Clinical Gastroenterology and Hepatology. The lowest levels of variation occur in patients with no

  • What are the Roles for Chemokines in Liver Disease?

What are the Roles for Chemokines in Liver Disease?

Sustained hepatic inflammation contributes to the progression of chronic liver diseases such as hepatitis C and non-alcoholic steatohepatitis. In the September issue of Gastroenterology, Fabio Marra and Frank Tacke review the roles of chemokines in liver inflammation and disease progression. In the liver, chemokines regulate the migration and activities of hepatocytes, Kupffer

Can Circulating Membrane Vesicles Promote Portal Hypertension?

Patients with cirrhosis have a large amount of circulating membrane vesicles—breakdown products from inflammation and liver cell damage. However, these ‘microparticles’ (MPs) are not simply debris; they contribute to the systemic vasodilation and portal hypertension associated with cirrhosis, according to the July issue of Gastroenterology. Patients with cirrhosis have persistent
