    Abstract:
    A total of 158 patients with pollinosis, bronchial asthma, urticaria and Quincke's edema were examined. The immunoglobulin and C3 levels in sera and the immunoglobulin and albumin levels in saliva were determined by the method of single radial immunodiffusion with the corresponding monospecific antisera. In all the groups of patients subjected to examination the presence of polyclonal hypergammaglobulinemia was detected, which was manifested by a rise in the levels of IgG, IgA and especially IgM; the level of IgD was low. A decrease in the level of C3 was detected in pollinosis patients in the absence of the exacerbation of the disease. No circulating immune complexes were detected. An essential increase in the level of IgG in saliva was revealed, which was due to the local synthesis of this immunoglobulin. In winter the level of salivary IgA in pollinosis patients was found to be essentially below normal, but at the period of exacerbation it increased twofold, probably in response to local stimulation with antigen-allergen. Patients with bronchial asthma and pollinosis were found to have a high level of free secretory component (SC); in pollinosis the level of free SC sharply increased during the stage of exacerbation, which was due to the increase of its synthesis and secretion by the epithelial cells of the mucous membranes. The importance of these data for the pathogenesis of allergic diseases are discussed.
