[Characteristics of secondary immunologic deficiency in children with chronic hepatitis B and the methods of its correction].

A study was made of the immune system of patients with chronic HB-viral infection who showed the signs of secondary immundeficiency. The high frequency of the impairment of immunocompetent cells seen in chronic hepatitis B was established as was the appearance of different-temperature autolymphocytotoxins in response to the infection of mono-nuclears in all the disease stages. The treatment with thymalin proved effective in patients with the lack of cold autolymphocytotoxins or in those with low activity of the latter ones.

[Dynamics of immunological indices in patients with chronic viral hepatitis B and the effect of thymalin therapy].

The work deals with the results of the study of T-lymphocytes and their subpopulations (active, thermostable, theophylline-sensitive and theophylline-resistant) in 102 children with chronic viral hepatitis B, depending on the effectiveness of thymalin therapy. The sensitization of lymphocytes to specific antigens was studied. Among patients with chronic viral hepatitis B and cirrhosis of the liver the homozygous phenotype of haptoglobin is registered essentially more frequently (63.
