How Do NS5A Inhibitors Prevent HCV Replication?

Researchers have uncovered the mechanisms of drugs that inhibit the hepatitis C virus (HCV) non-structural protein 5A (NS5A), described in the August issue of Gastroenterology. In a quantitative analysis of the kinetics of NS5A inhibitors, David R. McGivern et al.  show that these agents rapidly inhibit intracellular assembly of virions and

Podcast: How Does Fatty Liver Affect Risk for Cardiovascular Disease?

Modification of risk factors for cardiovascular disease—particularly dyslipidemia—is required to reduce morbidity and mortality in patients with nonalcoholic fatty liver disease (NAFLD). In a Perspective article published in the July issue of Clinical Gastroenterology and Hepatology, Kathleen E. Corey and Naga Chalasani discuss the increased risk of cardiovascular disease among patients with NAFLD, and strategies

How Can We Tell if Patients are Still at Risk for HCC after HCV Therapy?

For patients with chronic Hepatitis C virus infection, high levels of α-fetoprotein after therapy can identify those at risk for hepatocellular carcinoma (HCC), researchers report in the July issue of Clinical Gastroenterology and Hepatology. In persons with chronic HCV infection, lack of sustained virologic response (SVR) 24 weeks after the end

A Window of Opportunity for Treating Patients with Cirrhosis

Despite the ability of nonselective β blockers (NSBBs) to reduce portal pressure and lower the risk of variceal hemorrhage in patients with cirrhosis, these drugs have detrimental effects on those who have developed spontaneous bacterial peritonitis, researchers show in the June issue of Gastroenterology. Variceal hemorrhage, the most common lethal complication of

  • Does Cancer Treatment Bring Back HCV Infection?

Does Cancer Treatment Bring Back HCV Infection?

Treated hepatitis C virus (HCV) infections do not return after patients receive chemotherapy or immunosuppressive therapy, researchers report in the June issue of Clinical Gastroenterology and Hepatology. Cancer chemotherapy leads to HCV reactivation in patients with chronic infections, but little is known about the effect of chemotherapy on HCV infections

How Does Vitamin D Lower Cholesterol?

Researchers have identified a mechanism by which vitamin D reduces levels of cholesterol. In a mouse study published in the April issue of Gastroenterology, Edwin Chow et al. show that activation of the vitamin D receptor increases cholesterol 7α-hydroxylase (CYP7A1)—an enzyme that metabolizes cholesterol—by downregulating its repressor, SHP. Studies have
