Dermatitis herpetiformis and herpes gestationis. Analysis of γA and γM serum proteins by immunoelectrophoresis.

Serums from patients with dermatitis herpetiformis, herpes gestationis and pemphigus vulgaris were examined and compared with serums from normal individuals. Consistent deviations from normal were found, in that the γA globulin fraction was increased. The γM globulins appeared normal in dermatitis herpetiformis and herpes gestationis but decreased in pemphigus vulgaris. The γA and γM globulin changes in dermatitis herpetiformis and in herpes gestationis were similar.
