Hundred consecutive geriatric subjects between the age of 55-75 years (mean 60 ± 4) were analysed. All the smokers, whether male or female, had more than 40 pack year smoking index and the only mode of smoking had been cigarette and/or beedi. Twenty-eight per cent of the subjects had shown chronic air flow limitation. The air flow limitation was more severe in smokers than in non-smokers. IgA and IgM were significantly higher (p<0.001) in chronic obstructive pulmonary diseases (COPD) cases with no difference in smokers versus controls. It is observed that thymic-dependent IgG response is impaired in COPD subjects.
