[The clinical significance of immunodeficiency states in patients with viral hepatitis B].

Examination of 374 patients with acute viral hepatitis B made it possible to unravel certain mechanisms of the development of secondary immunodeficiency in the T immunity system: hypoxia and hypoxemia, activation of lipid peroxidation, suppression of antioxidant activity of blood serum, derangement of the synthesis of free radical forms of oxygen by mono- and polynuclear cells and ATR deficiency in them, disturbance of the interferonogenesis and synthesis of cyclic nucleotides, suppression of metabolic activity of immunocompetent cells. The character and intensity of immunodeficiency states underlie the formation of different clinical forms of viral hepatitis B.
