ABSTRACT
The prevalence of HCV infection varies throughout the world, with the highest number of infections reported in Egypt. Zinc has been closely related to the pathogenesis of chronic hepatitis C. Zinc deficiency causes reduction in glutathione [GSH] which has been implicated in various cellular events. Zinc may play an important role as a negative regulator in HCV replication; zinc supplementation increases the therapeutic response of Interferon [IFN]. To detect serum zinc concentration in adult patients with chronic [compensated] hepatitis C prior to treatment with IFN, and correlate the levels with the degree of inflammation and stage of fibrosis. This study was conducted on 40 adult patients chronically infected with HCV as well as 10 healthy subjects serving as a control group. Participants were subjected to complete clinical and laboratory assessment, quantitative analysis of HCV RNA by PCR technique and abdominal ultrasonography, in addition to estimation of serum Zinc by Graphite Furnace Atomic Absorption Spectrometer. A significant negative correlation was found between the level of zinc and liver fibrosis. The mean value of zinc in patients was 39.5ug/dl, while in the control it was 75ug/dl [normal range: 70-80ug/dl]. There was a non significant negative correlation between serum zinc and serum AST, ALT, disease activity and level of viraemia. Our study suggested the possible important protective role of zinc in patients with chronic hepatitis C, as serum zinc levels showed negative significant correlation with the stage of liver fibrosis
