Impact of hepatitis C virus infection on lifestyle
AIM: To evaluate the impact of the diagnosis of hepatitis C infection on lifestyle habits such as smoking, drinking, sports activity and diet. METHODS: A self-administered, anonymous question-naire was offered to out-patients with HCV infection consecutively attending three clinical centres in Italy. RESULTS: Of the 275 respondents, 62.2% (171) were male. Mean age was 51 (range 20-80) years. Overall, after the diagnosis of hepatitis C, 74.5% of drinkers had modified (giving up or reducing) alcohol consumption, 21.3% of smokers had modified their habits and 32.3% of subjects who reported sports activity had either stopped or reduced frequency of activity or chose a less fatiguing sport.

Accumulation of dysfunctional effector CD8+T cells in the liver of patients with chronic HCV infection
Background/Aims Hepatitis C virus (HCV) causes a chronic infection that can lead to fibrosis and carcinoma. Immune responses mediated by cytotoxic T lymphocytes (CTLs) could be involved in viral clearance or persistence, and therefore in determining the course of the disease. Methods Intrahepatic and peripheral blood CD8+T cells were obtained from 32 HCV-chronically infected patients and analysed by flow-cytometry for surface markers of differentiation, IFNγ and TNFα production, degranulation capacity and perforin content, after CD3 triggering. Results were compared with those obtained from 13 patients with a non-viral liver disease. Results Intrahepatic CD8+T cells of HCV-infected patients…
