BACKGROUND & AIMS Standard therapy for autoimmune hepatitis (AIH) is corticosteroids with or without azathioprine. However, 20% of patients do not respond or are intolerant to conventional treatment. Therefore, we evaluated prospectively the efficacy and safety of mycophenolate mofetil (MMF) in inducing and/or maintaining remission in treatment-naïve AIH(More)
Hepatitis C virus (HCV) infection is a global health problem that affects more than 170 million people worldwide. It is a major cause of cirrhosis and hepatocellular carcinoma, making the virus the most common cause of liver failure and transplantation. The standard-of-care treatment for chronic hepatitis C (CHC) has been changed during the last decade and(More)
For many decades, adipose tissue was considered as an inactive body compartment that was only used as an energy store. During the recent years, an increasing amount of data has revealed that adipose tissue is a major endocrine and paracrine organ producing numerous enzymes, hormones and growth factors which are collectively termed as adipokines. Several(More)
We studied the prevalence and clinical significance of anticardiolipin antibodies (aCL) in primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) as similar data are missing. Ninety-nine PBC patients, 41 PSC, 228 HCV, 50 HBV, 111 with other non-viral and non-autoimmune liver disorders and 267 healthy were investigated. In order to evaluate(More)
We describe, for the first time, two adult patients with primary biliary cirrhosis (PBC) who presented palpable purpuric lesions on the lower extremities and buttocks. Skin biopsy was consistent with Henoch-Schonlein purpura (HSP). One of the patients exhibited renal and gastrointestinal involvement, as well. A favourable outcome was achieved in both the(More)

Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and can progress to cirrhosis, liver failure, and hepatocellular carcinoma. In the last two decades, the prevalence of NAFLD has been growing in most developed countries, mainly as a consequence of its close association with obesity and diabetes mellitus. The exact(More)
To the Editor: I would like to thank Dr. Ross. (5) $100 million for antiviral therapy over 20 months is $5 million per month. This is clearly inadequate to treat 147,000 veterans with hepatitis C. This is why legislation should be passed so that all veterans with HCV immediately prequalify for their choice of Medicaid or Medicare. They could then obtain(More)
