ABSTRACT

This study devoted to 200 cases having obstructive pulmonary disease. The data concerning the human and environmental factors was collected through an observation sheet. Estimation of alpha[1-]antitrypsin of the serum was done in randomely selected 40 cases with obstructive pulmonary disease, besides 40 normal healthy individuals as a control using the immunodiffusion technique. In the studied cases with chronic obstructive pulmonary disease, there were 2 cases with severe deficiency and 10 cases with intermediate type of deficiency. Patients with severe deficiency developed their disease at a younger age than the others. Cigarette exposure was less intense in homozygotes than in heterozygotes and the difference was significant. It has been found that patients with homozygous antitrypsin deficiency develop their disease irrespective of smoking histories or exposure to air pollution but those with intermediate deficiency are prone to develop symptomatic obstructive pulmonary disease only if they smoke cigarettes or are exposed unduly to respiratory irritants during the course of their employment
