This work was carried out to evaluate T-helper liT-helper 2 (Thl/Th2) cytokine profiles in patients with occult HCV infection versus chronic hepatitis C (CHC) infection, also to investigate any association between theses cytokines and liver histological features in both groups. Serum levels of Thl cytokines (IL-2, IFN-y) and Th2 (IL-4 and IL-IO) were measured in 35 patients with occult HCV infection compared to 50 patients with chronic hepatitis C infection and 30 healthy controls. We have found that Thl cytokines were significantly increased in patients with CHC infection than in both occult HCV infection and control groups (p
