ABSTRACT
BACKGROUNDS/AIMS: Hepatitis B virus (HBV) infection and chronic alcoholism are major risk factors for chronic liver disease in Korea. METHODS: We investigated the prevalence of occult HBV infection in 198 non-alcoholic (group I) and 85 chronic alcoholic subjects (group II), none of whom showed the hepatitis B surface antigen (HBsAg). Among chronic alcoholics, 25 patients showed cirrhosis. Using serum samples stored at -70 degrees C, liver enzymes, anti-Hbs, and IgG anti-HBc were measured via EIA and serum HBV DNA was quantified via real time PCR. RESULTS: IgG anti-HBc seropositivity, an indicator of past infection, was higher in group II (64.7%) than in group I (43.4%; p<0.01). Eleven of 283 patients (3.2%) were seropositive for HBV DNA, indicating occult infection, but this value did not differ between groups (group I: 3.5%, 7/198; group II: 4.7%, 4/85; p=0.64). In group II, HBV DNA seropositivity was higher in cirrhotic patients (12%, 3/25) than in non-cirrhotic alcoholic liver disease (1.7%, 1/60; p=0.074). CONCLUSIONS: Past HBV infection was more prevalent in alcoholics than non-alcoholics, but the prevalence of occult HBV infection did not differ between groups. However, alcoholics with cirrhosis tended to show a higher prevalence of occult HBV infection.

Clinical trials of tumor necrosis factor (TNF) inhibitor have demonstrated significant efficacy in those patients with Crohn's disease that is not responsive to other anti-inflammatory drug. Infliximab is a human-murine chimeric monoclonal antibody with a high binding affinity and specificity for TNF-alpha. Yet therapy with infliximab is associated with an increased risk of opportunistic infection, and especially tuberculosis. Here we reported on a case of tuberculous meningitis in 26-year-old man, and he was treated with infliximab for uncontrolled and fistulous Crohn's disease. We also include a review of the literature.

There has been an increase in the number of patients treated with pegylated interferon (PEG-IFN) and ribavirin due to the better antiviral efficacy. The main serious adverse events of PEG-IFN plus ribavirin combination therapy are bone marrow suppression and hemolytic anemia. However, there are few reports of vasculitis occurring during PEG-IFN therapy. We describe a patient who developed vasculitis during the treatment of chronic hepatitis C with PEG-IFN and ribavirin.
