Abstract
Total levels of IgA, IgM, and IgG were measured in unstimulated whole saliva and serum from 63 individuals with selective IgA deficiency. Values were compared with the incidence of upper respiratory tract infections, antibiotic treatments (necessitated by upper respiratory tract infections), and HLA antigens. A statistically significant increase in salivary IgM and IgG levels was noted in individuals with selective IgA deficiency compared to healthy normal individuals. Healthy individuals with selective IgA deficiency did not have increased concentrations of salivary IgM compared to infectious-prone patients. Nor was there any correlation found between proneness to infections and HLA antigens or between salivary IgM or IgG levels and HLA antigens in this patient material.Keywords
