Hepatology

A three-year follow-up study of patients in the Hepatitis C Antiviral Long-term Treatment against Cirrhosis (HALT-C) trial revealed that increased mortality among patients with advanced chronic hepatitis C who received long-term peginterferon therapy was attributed to non-liver related causes and occurred primarily in patients with bridging fibrosis. No pattern to this excess mortality was evident to researchers, but deaths were unrelated to the peginterferon treatment. Full findings are published in the April issue of Hepatology, a peer-reviewed journal of the American Association for the Study of Liver Diseases (AASLD).

A two-year trial of entecavir followed by lamivudine (LAM) in patients with chronic hepatitis B virus (HBV) infection resulted in a virologic rebound rate of 24% and 12% drug-resistance rate. Patients who continued on entecavir therapy throughout the study period had undetectable HBV DNA at the two-year endpoint. Details of this trial are published in the April issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases.

New research has determined that patients in the U.S. with hepatitis C virus (HCV) are twice as likely to not have health insurance coverage compared with those without the disease. In fact researchers found only a third of HCV infected Americans have access to antiviral therapy; the remaining are either uninsured or not candidates for therapy due to treatment contraindications. Details of this study are published in the March issue of Hepatology, a peer-reviewed journal of the American Association for the Study of Liver Diseases (AASLD).

In two recent studies, researchers have identified two functional variants in the inosine triphosphatase (ITPA) gene that protect patients with hepatitis C virus (HCV) against anemia brought on by antiviral treatment. The ability to identify those patients protected against treatment-induced anemia will ensure completion of antiviral therapy and successful elimination of the virus. Full findings of these studies appear in the February issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases.

French researchers determined that infection with human immunodeficiency virus (HIV) impaired results of transplant surgery for liver cancer, with more HIV infected patients dropping off the transplantation wait list. The team found that overall survival and recurrence-free survival was not impacted following liver transplantation in patients with controlled HIV disease. Details of this single center study—the largest to date—are published in the February issue of Hepatology, a peer-reviewed journal of the American Association for the Study of Liver Diseases (AASLD).

Researchers from Italy determined that radiofrequency ablation (RFA) is a safe and effective therapy for managing hepatocellular carcinoma (HCC) in cirrhotic patients. The high repeatability of RFA is advantageous in controlling recurrences of cancerous tumors in the liver. Results of this 10-year retrospective study are available in the January 2011 issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases (AASLD).

A new study by German researchers found that a variation in the PNPLA3 (adiponutrin) gene was associated with cirrhosis of the liver and elevated transaminase (liver enzyme) levels in alcoholic Caucasians. The risk of cirrhosis in alcoholics in the genetic high risk group might be as high as 25 to 50%. Full findings are published in the January 2011 issue of Hepatology, a journal of the American Association for the Study of Liver Diseases.

An Italian research team confirmed that the scoring system for Wilson’s disease (WD) provides good diagnostic accuracy with 93% positive and 92% negative predictive values, respectively in children with mild liver disease. In asymptomatic children, a urinary copper excretion above 40 μg/24 hours was suggestive of WD, however the penicillamine challenge test (PCT) did not provide an accurate diagnosis in this patient subset. Results of the study appear in the December issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases (AASLD).

New research shows that anti-microbial medications are a common cause of drug-induced liver injury (DILI) leading to acute liver failure (ALF), with women and minorities disproportionately affected. While ALF evolves slowly, once it does occur a spontaneous recovery is unlikely; however liver transplantation offers an excellent survival rate. Full findings of this ten-year prospective study are published in the December issue of Hepatology, a journal of the American Association for the Study of Liver Diseases.
