Th antiviral activity and iron metabolism in small animal models or possible clinical 15900046 studies. However, well-designed clinical studies addressing safety and longterm efficacy are needed in order to clarify the risks and benefits of hepcidin-targeted treatment. In summary, we show for the first time that hepcidin can attenuate HCV replication and that this antiviral activity is through activation of STAT3. A strategy to augment hepcidin expression or hepcidin enhancing agents may be an effective therapy to treat patients with chronic MedChemExpress CASIN hepatitis C, including those with existing interferon resistance.Hepcidin Exhibits Antiviral Activity against HCVAcknowledgmentsWe thank Jason Zakkoja and Ton Wang for critical reading of the manuscript and Xiaokui Zhang for technical support.Author ContributionsConceived and designed the experiments: CL HYL.

Immunogenicity and Acceptance of Influenza A (H1N1) Vaccine in a Cohort of Chronic Hepatitis C Patients Receiving Pegylated-Interferon Treatment???Manuel Hernandez-Guerra1,2*, Yanira Gonzalez-Mendez1, Patricia de Molina3, Antonio Z.

Chronic hepatitis C (CHC) patients receiving treatment might be at a higher risk of respiratory bacterial infections after influenza infection. However, there are no observational studies evaluating the immunogenicity, tolerance and acceptance of 2009 
influenza A vaccine in CHC patients. Methods: We evaluated the immunogenicity of influenza A vaccine (PandemrixH) by using the hemagglutination inhibition (HI) titers method in a well defined cohort of CHC patients receiving or not receiving pegylated-interferon and ribavirin, and compared it with healthy subjects (controls). A group of patients with inflammatory bowel disease (IBD) under immunosuppression, thought to 
have a lower immune response to seasonal influenza vaccine, were also included as a negative control group. In addition, tolerance to injection site reactions and acceptance was assessed by a validated questionnaire (Vaccinees’ perception of injection-VAPI-questionnaire). Results: Of 114 subjects invited to participate, 68 accepted and, after exclusions, 72 were included. Post-vaccination geometric mean titers and seroprotection/seroconversion rates were optimal in CHC patients with ongoing treatment (n = 15; 232, CI95 46?166; 93 ; 93 ), without treatment (n = 10; 226, CI95 69?43: 100 ; 100 ) and controls (n = 15;168, CI95 42?80; 93 ; 86 ) with no differences between groups (P = 0.8). In contrast, IBD patients had a significantly lower immunogenic response (n = 27; 60, CI95 42?80;66 ;66 ; P = 0.006).
