Acute allergic reaction and demonstration of specific IgE antibodies against alpha-1-protease inhibitor.
A 44 yr-old female with severe pulmonary emphysema and reduced alpha-1-protease inhibitor (alpha1-PI) serum levels developed an acute anaphylactic reaction following the third intravenous infusion of human alpha1-PI which was administered to prevent the progression of pulmonary emphysema. Specific immunoglobulin E-antibodies against human alpha1-PI could be demonstrated in the patient's serum using an enzyme allergosorbent test. Because of the risk of further severe anaphylactic reaction, the replacement therapy with alpha1-PI was discontinued. Physicians should be aware of this rare complication.
