Chronic bronchitis: IgA and C3 in acute exacerbations.
Serum IgA, secretory IgA and serum C3 were estimated in 22 patients of chronic bronchitis with acute exacerbation. These were compared with 22 normal controls. There was no significant difference in the parameters studied. However, all patients showed a significant change in the above parameters when divided into mild, moderate and severe categories depending on the chronicity of the disease. An inverse relationship between serum C3 and secretory IgA was observed.
