This work builds upon the groups' previous research demonstrating liver disease in highly-exposed chemical workers. The study is being presented during Digestive Disease Week 2009 (DDW), the largest international gathering of physicians and researchers in the fields of gastroenterology, hepatology, endoscopy and gastrointestinal surgery. http://www.physorg.com/news162815194.html Medicine & Health Fri, 29 May 2009 11:27:06 EST news162815194 Two new studies address donor factors that could affect outcomes for liver transplant recipients, particularly those with chronic hepatitis C (HCV). One found that donor steatosis, or fat in the liver, does not affect liver disease progression or three-year survival in recipients with or without HCV. However, transplants from people higher on the Donor Risk Index did adversely affect the outcomes of HCV-positive recipients more than recipients without HCV. http://www.physorg.com/news162740009.html Medicine & Health Thu, 28 May 2009 14:33:52 EST news162740009 A new combination therapy of daily consensus interferon (CIFN) and ribavirin is effective for some people with chronic hepatitis C (HCV) who do not respond to standard therapy. The treatment works particularly well in interferon-sensitive patients who have lower fibrosis scores, according to a new study in the June issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD). http://www.physorg.com/news162739824.html Medicine & Health Thu, 28 May 2009 14:30:41 EST news162739824 A technique that `silences,` or turns off, genes shows promise as a potential new treatment for liver fibrosis - the disease that leads to cirrhosis - scientists in Tennessee are reporting. Their study is scheduled for the June 1 issue of ACS` Molecular Pharmaceutics.

One potential route is through veterinarians, who, according to a new report by University of Iowa College of Public Health researchers, are at markedly increased risk of infection with zoonotic pathogens -- the viruses and bacteria that can infect both animals and humans. http://www.physorg.com/news161606092.html Medicine & Health Fri, 15 May 2009 11:35:28 EST news161606092 A main reason why viruses such as HIV or hepatitis C persist despite a vigorous initial immune response is exhaustion. The T cells, or white blood cells, fighting a chronic infection eventually wear out. http://www.physorg.com/news161454772.html Medicine & Health Wed, 13 May 2009 17:33:37 EST news161454772 High serum ferritin, being a hallmark of hereditary hemochromatosis , is frequently found in chronic hepatitis C, alcoholic or non-alcoholic steatohepatitis and non-alcoholic fatty liver disease patients . A study in Italy has investigated the link between ferritin and steatosis in a non-obese cohort of non-alcoholic patients. In southern European populations, high ferritin levels, after exclusion of diagnosis of HH, represent a risk factor for steatosis and clinical relevance, being associated with low platelet count. http://www.physorg.com/news161443860.html Medicine & Health Wed, 13 May 2009 14:31:40 EST news161443860 (AP) -- The top Veterans Affairs official in Miami said Tuesday she has taken steps locally to prevent the kind of problems that exposed patients to contaminated medical equipment at VA hospitals in three states. http://www.physorg.com/news161364220.html Medicine & Health Tue, 12 May 2009 16:32:23 EST news161364220 Dengue fever is the most common infectious disease transmitted by mosquitoes - some 100 million people around the world are infected.

Hepatology is a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD). http://www.physorg.com/news157809387.html Medicine & Health Wed, 01 Apr 2009 12:56:47 EST news157809387 At least 200 million individuals are currently infected with hepatitis C virus (HCV) worldwide. Approximately 30%-50% of patients respond to interferon/ribavirin combination therapy. Response to interferon therapy depends mainly on viral and host genetic factors. The HCV is continually mutating which allows the virus to evade the immune system and overcome interferon treatment. http://www.physorg.com/news157632931.html Medicine & Health Mon, 30 Mar 2009 11:56:25 EST news157632931
