Alpha-1-antitrypsin phenotypes were determined in 37 patients with rheumatoid arthritis and 40 patients with systemic lupus erythematosus. No significant increase in non-MM phenotypes was found. It appears that alpha-1-antitrypsin phenotypes neither predispose to the development nor enhance the severity of the two rheumatic diseases.
