Abstract
Objective. To identify the relationship between immunological parameters and the severity of liver fibrosis (LF) in patients with chronic hepatitis C (CHC).
Subjects and methods. Examinations were made in 69 men and 48 women (mean age 45.7 ± 2.1 years) with a confirmed diagnosis of CHC. The number and functional activity of T lymphocyte subpopulations were studied by flow cytofluorometry using an EPICS XL cytometer (Beckman Coulter, USA). The serum concentration of interferons (IFN-α, IFN-γ, and IFN-λ) was estimated by an enzyme-linked immunosorbent assay (ELISA). Liver fibroelastometry was performed using a Fibroscan 502 device (Echosens, France), whereas the stage of fibrosis was determined using the METAVIR scoring system.
Results. An increase in the total number of T lymphocytes and T helper cells was detected in patients with CHC at all stages of LF. A significant decrease was found in B lymphocytes in patients with fibrosis stages F3 and F4. There was a tendency of IFN-α to decrease and IFN-λ to increase with progression of fibrosis stage.
Conclusion. The findings not only confirm the opinion about the pronounced immunosuppressive effect of viral hepatitis C, but also emphasize the importance of T cell immunity and IFN-γ in the prognosis of severe LF.
