INTRODUCTION Liver biopsy remains the gold standard to evaluate fibrosis. However, it is invasive and uncomfortable as well as associated with complications. Transient elastography (FibroScan) is a simple and noninvasive method to assess liver fibrosis by measuring liver stiffness in kilopascals. Body mass index (BMI) greater than 28 is associated with high(More)
Hepatitis C virus causes significant morbidity and mortality worldwide. The infection induces up-regulation of cytokine and chemokines commonly linked to the development of cellular and pro-inflammatory antiviral responses. The current standard in hepatitis C treatment consists of combination regimens of pegylated interferon-alpha plus ribavirin. The impact(More)
The effects of oral administration of valproic acid (VPA) have been studied on the liver of female adult Wistar rats, at doses of 60 and 120 mg/kg/day during 4 and 18 weeks (periods I and II). Other groups received the same doses of VPA with phenobarbital (PB). The animals developed periportal steatosis, more intense at the end of period II and in groups(More)
BACKGROUND Biliary complications, a major source of morbidity after orthotopic liver transplantation (OLT), are increasingly being treated by endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic management has been shown to be superior to percutaneous therapy and surgery. Covered self-expandable metal stents (CSEMSs) may be an alternative to(More)
BACKGROUND The diagnostic efficacy of current tissue sampling techniques for upper GI subepithelial tumors (SETs) appears to be limited. Better tissue acquisition techniques are needed to improve the diagnostic yield in this setting. OBJECTIVE Our purpose was to determine the safety and diagnostic yield of EUS-guided needle-knife incision and forceps(More)
OBJECTIVE Our aim was to prospectively compare the behavior of interleukin 18 (IL-18) levels and other immunological parameters during the first week of hospitalization between acute pancreatitis patients with and without severity criteria, as well as between patients with and without late pseudocyst development. PATIENTS AND METHODS In 36 patients with(More)
