Dynamics of proinflammatory cytokines serum levels during viral hepatitis type A.

In this study we assessed the dynamics concerning IL-2, sLL-2R and IL-4 serum levels in the course of an acute viral hepatitis A infection. The study group consisted of 48 persons. The serum concentrations of IL-2, sIL-2R and IL-4 were assessed with the use of ELISA methods. In patients the assessments were done twice--in the first and third week of the hospitalisation. In the control group, which consisted of 24 healthy persons the assessments were done once. The obtained data were analysed with the use of c-Cochran and Cox statistical test. We observed a statistically important decrease in IL-2 and IL-4 serum levels in patients with acute viral hepatitis A infection in the first week of the hospitalisation compared to values observed in the control group. We also observed an increase in sIL-2R levels in the course of the disease. The dynamics of IL-2, sIL-2R and IL-4 serum levels in patients with acute hepatitis A infection was of a random type. The assessment of IL-2, sIL-2R and IL-4 serum levels can be helpful in examining the cellular response in viral hepatitis A infection.
