Abstract:
Immunopathological investigations (demonstration of IgG, IgM, IgE, SIgA and C3) of bronchial mucosa in 32 cases of chronic bronchitis showed in 1/5 of all cases deposits of immunoglobulins of the IgG, M and E class in the basal membrane. The complement factor C3 was found in 1/10 of all cases. SIgA was seen in only 55%. There is a close correlation between the loss of SIgA and deposits of immunoglobulins (IgG, IgM, IgE) in the basal membrane.
