[Clinical evaluation of the structural characteristics of peripheral blood leukocyte DNA in patients with viral hepatitis B].

The DNA structure of peripheral blood leukocytes in healthy donors and in viral hepatitis B patients was studied by the rate of the alkaline denaturation of DNA in cell lysates. An increased rate of the DNA alkaline denaturation of cell lysates was established, which was indicative of the damages in their DNA. The most pronounced damages of DNA were found in granulocytes of patients with highly active chronic hepatitis and hepatic cirrhosis, especially in cases of simultaneous delta-virus infection.

[The interferon therapy of patients with chronic viral hepatitis: the factors affecting the treatment results].

The paper presents clinicoimmunological characterization or therapeutic efficacy of alpha-interferons produced in Russia and criteria of their administration in patients with chronic viral hepatitis. A 6 to 12 months course (single dose 1 x 10(6)-3 x 10(6) IU improves the disease running, hepatic function and corrects immune status in 55.6% of patients with chronic active hepatitis eventuating in liver cirrhosis and in 57.

[The problem of the interferon therapy of patients with chronic viral hepatitis].

In this work the results of the clinico-immunological evaluation of the therapeutic effectiveness of alpha-interferon preparations are presented and criteria suitable for use in screening patients with chronic virus hepatitis, sensitive to interferon therapy, are discussed. The study revealed that the use of alpha-interferon preparations in single doses of 1-3 x 10(6) in a prolonged course of treatment (6-12 months) facilitated essential improvement in the clinical course of the disease and ensures correction of the immune status in 55.6% of patients with chronic active hepatitis (CAH) resulting in cirrhosis of the liver and 57.

[The interferon status and cellular immunity of pregnant women with viral hepatitis B].

The examination of 62 pregnant women with acute viral hepatitis B has established in them inhibition of interferon genesis and the presence of secondary T-cell immunodeficiency. The most pronounced and long-lasting was a fall of gamma-interferon. A simultaneous lowering of alpha-, gamma- and serum interferon was indicative of complicated pregnancy or premorbid condition.

[The treatment of patients with chronic persistent hepatitis B with interferon preparations].

Alpha-interferon preparations were injected intramuscularly in a single weekly dose 1.10(6) - 1.5.
