[Cell-mediated and humoral immunity in HBS-Ag carriers]
The presence of HBs--Ag in the blood was established in 1.8% of practically healthy persons, in 29.7% of virus hepatitis patients and in 86.0% of serum hepatitis patients. The immunological study of clinically healthy HBs--Ag carriers revealed a statistically significant decrease in the number of T and B lymphocytes and an increased level of serum IgA, IgM and IgG in the blood. Among donors, 7.6% were found to have lymphocytes sensitized to HBs--Ag and 15.4% were found to have lymphocytes sensitized to liver antigen, while for HBs--Ag carriers these data were 62.5% and 50%, respectively.
