Replacement therapy for hereditary alpha1-antitrypsin deficiency. A program for long-term administration.

This retrospective chart review describes the efficacy and safety of long-term administration of intravenous alpha1-antitrypsin (AAT) in 14 patients with hereditary AAT deficiency and COPD. During the 12- to 48-month observation period, 12 to 14 patients had stabilization of functional status; 4 patients had reductions in hospitalizations. Thirteen of 14 patients had no decline in pulmonary function. Three patients had self-limited adverse reactions to the AAT with one patient requiring a brief hospitalization.
