We describe a patient in whom selective IgA deficiency and homozygous alpha1-antitrypsin deficiency were discovered. Clinically, the patient suffered from chronic sinopulmonary infections, destructive emphysema, and bronchiectasis. The interrelation of IgA and alpha1-antitrypsin was studied. Twenty-three alpha1-antitrypsin-deficient sera were screened for IgA deficiency. None of these sera were deficient in IgA. Fifteen IgA-deficient sera were screened for alpha1-antitrypsin deficiency. In this group, three patients were found to have variant alpha1- antitrypsin phenotypes. Respiratory infections were a prominent complaint in all three of these patients, with bronchiectasis in two patients. We believe that the combination of IgA and alpha1-antitrypsin deficiencies should be considered in the evaluation of any patient with idiopathic bronchiectasis.
