Summary
Brief summary
In previous studies the addition of zinc to standard therapy of hepatitis C induced limited benefits on viral response and some of these studies have reported improved transaminases with zinc therapy. It is important to notice that a group of the hepatitis C patients have beta thalassemia major as well and combination therapy with INF-a plus ribavirin should be suggested for them . Zinc depletion has been reported in patients with beta thalassemia major under treatment of chelator agents such as deferioxamine, deferiprone and deferasirox. Using of zinc accompanied with standard regimen may have a benefit in pharmacotherapy of chronic hepatitis C with beta thalassemia major.So the aim of present study was to evaluate the effect of zinc administration on viral response in patients with chronic hepatitis
