High Prevalence of Viral Infection in Adults with Homozygous and Heterozygous Alpha₁-Antitrypsin Deficiency and Chronic Liver Disease

Abstract

Chronic liver disease in patients with alpha 1-antitrypsin deficiency is associated with a high prevalence of viral infection; this infection, rather than alpha 1-antitrypsin deficiency alone, may be the cause of the liver disease in such patients.
