BACKGROUND Acoustic Radiation Force Impulse Imaging (ARFI) is an innovative elastography for staging of liver fibrosis. We evaluated the diagnostic accuracy of different probes to perform ARFI at different insertion depths. METHODS In a prospective study, 89 chronic HCV infected patients underwent ARFI elastography using both available probes (c-ARFI:(More)
BACKGROUND AND AIMS Transient elastography is increasingly being used in patients with chronic liver disease. It has proven particularly useful to identify patients with advanced fibrosis or cirrhosis, while classification of no or little fibrosis appears to be difficult. In general, stiffness values <6 kPa are considered normal, whereas patients with(More)
BACKGROUND HCV protease inhibitors (PIs) boceprevir and telaprevir in combination with PEG-Interferon alfa and Ribavirin (P/R) is the new standard of care in the treatment of chronic HCV genotype 1 (GT1) infection. However, not every HCV GT1 infected patient is eligible for P/R/PI therapy. Furthermore phase III studies did not necessarily reflect real world(More)
Hepatitis delta virus (HDV) is the most severe form of viral hepatitis. Pegylated interferon alfa (PEG-IFNα) is effective in only 25%-30% of patients and is associated with frequent side effects. The aim of this study was to analyze the clinical long-term outcome of hepatitis delta in relation to different antiviral treatment strategies. We studied 136(More)
Determination of hepatitis D virus (HDV) viremia represents the "gold standard" for the diagnosis of HDV infection. Hepatitis B virus (HBV)-HDV coinfection frequently leads to end-stage liver disease and hepatocellular carcinoma. No commercial assay for HDV RNA quantification that includes automated nucleic acid extraction is available, and in-house PCR(More)
BACKGROUND Hepatitis delta frequently leads to liver cirrhosis and hepatic decompensation. As treatment options are limited, there is a need for biomarkers to determine disease activity and to predict the risk of disease progression. We hypothesized that anti-HDV IgM could represent such a marker. METHODS Samples of 120 HDV-infected patients recruited in(More)
BACKGROUND & AIMS Several real world data demonstrated that eligibility for and tolerability of triple therapy against hepatitis C virus (HCV) infection with a first-wave protease inhibitor is limited. With the approval of sofosbuvir (SOF) effective treatment with and without pegylated interferon (PEG-IFN) has become available for most genotypes. However,(More)
BACKGROUND  Hepatitis D virus (HDV) infection affects 15-20 million individuals worldwide and causes severely progressive hepatitis. It is unknown to what extent cellular immune responses contribute to liver disease and control of viral replication in HDV infection. METHODS  Immune cell frequencies and phenotypes were determined in 49 HDV-infected(More)
BACKGROUND AND OBJECTIVE HCV is transmitted mainly by parenteral routes. However, unprotected anal intercourse has also been identified as a risk factor for HCV infection. HCV RNA can be detected in blood, saliva, and bile, but the presence of HCV in stool has not been investigated yet. STUDY DESIGN Therefore, stool samples of 98 patients were collected(More)
BACKGROUND & AIMS The importance of the intestinal microbiota for the onset and clinical course of many diseases, including liver diseases like non-alcoholic steatohepatitis and cirrhosis, is increasingly recognized. However, the role of intestinal microbiota in chronic hepatitis C virus (HCV) infection remains unclear. METHODS In a cross-sectional(More)
