BACKGROUND & AIMS Therapy of chronic hepatitis B with HBV-polymerase inhibitors, in particular tenofovir or adefovir, may affect renal function. To assess renal function more accurately in the normal range, we used the recently validated, Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula to calculate the estimated glomerular filtration(More)
UNLABELLED Tenofovir disoproxil fumarate (TDF) has demonstrated high antiviral efficacy in treatment-naive patients with chronic hepatitis B virus (HBV) infection but experience in nucleoside/nucleotide analogue (NA)-experienced patients is limited. In this retrospective multicenter study we therefore assessed the long-term efficacy of TDF monotherapy in(More)
Incomplete virological response to adefovir dipivoxil (ADV) has been observed in patients with lamivudine-resistant hepatitis B virus (HBV) infection and may be associated with developing resistance and disease progression. We therefore investigated whether the efficacy of viral suppression could be improved by replacing ADV with tenofovir disoproxil(More)
The current preferred treatment for patients with hepatitis C virus (HCV) is combination therapy consisting of pegylated interferon alfa and ribavirin (RBV) for 24-48 weeks. Although this approach appears to be highly effective for patients with HCV genotypes 2 or 3, who have a sustained virological response (SVR) of approximately 80%, the treatment(More)
BACKGROUND Viral hepatitis is major a public health problem affecting millions of people worldwide. Estimates assume 400 000-500 000 people chronically infected with hepatitis C virus (HCV) in Germany. Long-term consequences are the development of liver cirrhosis and hepatocellular carcinoma. The aim of the study was to assess the costs for treating(More)
Surveillance colonoscopy is an important strategy for prevention of colorectal cancer. 5-aminosalicylate (ASA) (mesalazine) is discussed as a chemopreventive agent as it reduces the cancer risk in ulcerative colitis patients. The current study analyses the effect of 5-ASA on Wnt/β-catenin signaling in vitro and in vivo in colon epithelial cells. The effect(More)
BACKGROUND Adequate bowel preparation is essential for accurate colonoscopy. Both oral sodium phosphate (NaP) and polyethylene glycol-based lavage (PEG-ELS) are used predominantly as bowel cleansing modalities. NaP has gained popularity due to low drinking volume and lower costs. The purpose of this randomized multicenter observer blinded study was to(More)
BACKGROUND The aim of this cross-sectional study was to establish an online inflammatory bowel disease (IBD) registry for a first picture of the situation of IBD outpatients' treatment in Germany. METHODS Between March 2006 and July 2007 IBD outpatients from 24 gastroenterological specialist practices and two hospitals in Germany were enrolled in an(More)
Multiple clinical trials have demonstrated the efficacy and safety of tenofovir disoproxil fumarate (TDF) in chronic hepatitis B (CHB). However, long-term efficacy and safety data for TDF in real-life clinical practice are limited. Prospective German field practice study in CHB-mono-infected patients. Patients were TDF-naïve but could have been treated(More)
AIM To evaluate the safety and efficacy of pegylated interferon alfa-2a and ribavirin therapy in elderly patients with chronic hepatitis C infection. METHODS Patients characteristics, treatment results and safety profiles of 4859 patients with hepatitis c virus (HCV) infection receiving treatment with pegylated interferon alfa-2a and ribavirin were(More)
