Herbal products, used for centuries in Far Eastern countries, are gaining popularity in western countries. Surveys indicate that persons with chronic hepatitis C (CHC) often use herbals, especially silymarin (milk thistle extract), hoping to improve the modest response to antiviral therapy and reduce side effects. The Hepatitis C Antiviral Long-Term Treatment Against Cirrhosis (HALT-C) Trial, involving persons with advanced CHC, nonresponders to prior antiviral therapy but still willing to participate in long-term pegylated interferon treatment, offered the opportunity to examine the use and potential effects of silymarin. Among 1145 study participants, 56% had never taken herbals, 21% admitted past use, …

BACKGROUND: Excessive alcohol use results in impaired immunity, and it is associated with increased incidence and progression of chronic hepatitis C virus (HCV) infection. Here we investigated the effects of HCV infection and alcohol on myeloid dendritic cells (DC) that are critical in antiviral immunity.

METHODS: Immature and mature DCs were generated from monocytes of chronic HCV infected patients (HCV-DC) and controls (N-DC) with IL-4 plus granulocyte-macrophage colony stimulating factor (GM-CSF) in the presence or absence of alcohol (25 mM). DC allostimulatory capacity was tested in mixed lymphocyte reaction (MLR) and cytokine production by ELISA.

RESULTS: Allostimulatory capacity of HCV-DCs …

Pathogenic Interactions Between Alcohol And Hepatitis C, Gyongyi Szabo

Alcohol is the most commonly abused substance in the United States, and alcohol abuse leads to alcoholic liver disease, a long recognized major public health concern. The high prevalence of chronic hepatitis C virus (HCV) infection, along with the clinical observation that HCV infection is common in alcoholic patients presenting with liver disease, has directed attention to the interaction between alcohol and HCV infection. Clinical studies have identified alcohol use as an independent risk factor for progression of fibrosis in chronic HCV infection. Experimental evidence suggests additive inhibitory effects between HCV and alcohol on antiviral immune responses. In addition, specific …

Complete Resolution Of Gastric Amyloidosis After Autologous Stem Cell Transplantation., Dinu Cherian, Kristin Braun, Neal Flomenberg, Juan P. Palazzo, David Kastenberg

A 48-year-old female with multiple myeloma (MM) and amyloidosis presented with massive upper gastrointestinal (GI) bleeding one week after autologous stem cell transplantation (autologous-SCT). Esophagogastroduodenoscopy (EGD) demonstrated necrotic, purple, pigmented, friable lesions throughout the stomach (Figure 1a), along with a bleeding ulcer in the cardia (Figure 1b, Video 1) which was successfully treated with epinephrine (1:10,000) injections. Biopsies demonstrated nodular amyloid deposition (Figures 2) which was Congo red positive. The patient had no further hematemesis and was discharged home 4 days later. Ten months after autologous-SCT, EGD revealed a normal stomach (Figure 3, Video 2) with …
