Peripheral blood T lymphocytes and T cell subsets were analyzed in 19 patients with chronic active hepatitis B virus infection. The T cell subpopulations were defined by indirect immuno-fluorescence using monoclonal antibodies, and additionally, natural killer cell activity against K 562 human erythroleukemic cell has also been defined. All investigated patients have possessed nearly identical clinical and biochemical signs of disease, but on the basis of T lymphocyte subpopulations they could be divided into two groups: low CD4/CD8 ratio group and normal or high CD4/CD8 ratio group. Mechanism responsible for such differences remains hypothetical but it seems reasonable to propose different protocol for immunomodulatory treatment of patients in both groups.
