BACKGROUND Proton beam therapy (PBT) may provide useful local-regional treatment for hepatocellular carcinoma (HCC). The purpose of this study was to evaluate the safety and efficacy of PBT for HCC. METHODS Patients with cirrhosis who had radiological features or biopsy-proven HCC were included in the study. Patients without cirrhosis and patients with(More)
Approximately 40% of patients with chronic hepatitis C virus (HCV) infection develop detectable serum cryoglobulins or cryoprecipitates (CP), although most do not show clinical or physical signs of syndromic cryoglobulinemia. Although association of HCV with the extrahepatic complications of cryoglobulinemia is widely recognized, the relationship of(More)
AIM Although hepatic iron deposition unrelated to hereditary hemochromatosis is commonly observed in cirrhosis, its clinical significance is unclear. The aim of this study was to examine the outcomes of cirrhotic patients with and without hemosiderosis. METHODS Patients with an initial liver biopsy demonstrating cirrhosis between January 1993 and December(More)
BACKGROUND AND AIMS Increased levels of nitric oxide (NO) are hypothesized to contribute to renal dysfunction in patients with decompensated cirrhosis. In this study, we examined whether splanchnic and/or peripheral NO levels and L-arginine (L-Arg) correlate with progressive renal dysfunction in cirrhotics. METHODS Serum NO metabolites (NOx) and L-Arg(More)
Mixed cryoglobulinemia (MC) is a syndrome resulting from cold-insoluble immunoglobulin complexes or cryoglobulins (CGs) that precipitate in the serum of 40% to 50% of patients with chronic hepatitis C virus (HCV) infection. The pathogenesis of cryoglobulinemia likely occurs due to chronic viremia and generation of rheumatoid factor following continuous(More)
Chronic Hepatitis C virus (HCV) infection is the leading cause of advanced liver disease worldwide. The virus successfully evades host immune detection and for many years has hampered efforts to find a safe, uncomplicated, and reliable oral antiviral therapy. Initially, interferon and ribavirin therapy was the treatment standard of care, but it offered(More)
Chronic hepatitis C virus (HCV) infection causes cirrhosis in many infected patients; however, a better understanding of the risk factors for fibrosis progression in high HCV prevalence groups such as US veterans is needed. We wished to compare the demographic, clinical characteristics, and independent variables that influence fibrosis in US veterans vs(More)
Two cases of gastrointestinal hemorrhage resulting from Dieulafoy-like lesion of the rectum are presented. Both patients developed acute episodes of massive lower gastrointestinal hemorrhage requiring transfusions. Colonoscopy was performed in both instances and lesions were localized. The patients were successfully treated by alcohol and epinephrine(More)
Fibrosis in livers with hepatitis C virus (HCV) recurrence after liver transplantation (LT) can be rapidly progressive, and the mechanisms underlying this process are poorly understood. In livers with HCV infections in the non-LT setting, there is a significant relationship between the development of structures known as the ductular reaction (DR), hepatic(More)
Oxidation-reduction potential (ORP) is a newer integrated measure of the balance between total oxidants (reactive oxygen species-ROS) and reductants (antioxidants) that reflects oxidative stress in a biological system. This study measures ORP and evaluates the effect of exogenous induction of oxidative stress by cumene hydroperoxide (CH) on ORP in fresh and(More)
