Detection of gluten in human sera by an enzyme immunoassay: comparison of dermatitis herpetiformis and celiac disease patients with normal controls.
We have developed a triple sandwich enzyme immunoassay to detect circulating gluten in human sera. With human sera containing known amounts of added gluten as controls, the assay was sensitive in the range of 0.75 to 75 micrograms of gluten per ml of serum. Forty-one control subjects were compared to 21 patients with dermatitis herpetiformis and 11 patients with celiac disease. The dermatitis herpetiformis and celiac disease patients had significant elevation of serum gluten values over the control subjects. Circulating gluten antigenemia is a previously unrecognized feature which may be important in understanding the pathogenesis of dermatitis herpetiformis and celiac disease.
