Alpha 1-antitrypsin serum concentration and phenotypes in ulcerative colitis.
Biemond I., Selby WS., Jewell DP., Klasen EC.
96 unrelated patients suffering from ulcerative colitis were typed for the electrophoretic variants of alpha 1-antitrypsin (alpha 1-AT). None of the phenotypes showed a definite association with this condition. The serum concentration of alpha 1-AT was increased compared with healthy control subjects. There was a positive correlation between the serum concentration of alpha 1-AT and activity of the ulcerative colitis.
