A total of 40 patients with asymptomatic HCV infection were involved in this study at Immunology Department of Military Hospital 108. Frequency of elevated transaminase was 27,5%. The change of amount of TCD4, TCD8, TCD3, B cell was found in 75%. Subjects were divided in to 2 groups: patients with asymptomatic HCV infection and elevated transaminase (group A) and asymptomatic HCV patients without elevated transaminase (group B). Number of TCD4, TCD8, TCD3, BCD19 increased significantly in group A, higher than in group B and controls. There was positive correlation between increasing TCD4, especially TCD8 with transaminase. Response of both T cell and B cell was shown in group A.

Results: the coinfection of HCV/HBV was 23% at group of patients with viral hepatitis, 22% in group of prisoners, 0% in group of venereal disease, normal people in urban areas, people lived in coastline and in islands. Coinfections of HBV/HCV were 47% at group of patients with viral hepatitis, 6% in prisoners. 0% in group of venereal diseases, normal people in urban areas, people lived in islands.
