Cleve Clin J Med · 2002

Where this comes from

Abstract

Nonsmokers with signs of emphysema at an earlier age than is typical for emphysema deserve a workup for one of the less common causes of emphysema, which include alpha 1-antitrypsin deficiency, connective tissue diseases, hypocomplementemic urticarial vasculitis syndrome, intravenous drug use, human immunodeficiency virus infection, and several rare metabolic disorders.
