[Secretory humoral immunity in children with chronic viral diseases of the liver].

The content of IgE, IgG, IgM and secretory IgA was measured in the stomatopharyngeal secretion (saliva) and in the intestinal secretion (coprofiltrates) of 58 patients aged 3 to 15 years suffering from chronic viral hepatitis and liver cirrhosis. It has been established that in addition to hyperimmunoglobulinemia, children with chronic viral diseases of the liver manifested elevated synthesis of immunoglobulins in the system of local immunity, including a high content of IgE in the alimentary secretions, thus pointing to enhanced antigenic stimulation occurring in this pathology.
