Leucocyte migration inhibition test with two gastric antigens in pernicious anaemia and in simple atrophic gastritis.

Abstract

Leucocyte migration inhibition test was used for evaluation of cell-mediated immunity in patients with pernicious anaemia (PA) and simple atrophic gastritis (SAG). As antigens microsomal antigen from gastric mucosa of swine foetus and relatively pure hog intrinsic factor (IF) were used. Significant differences were found between PA and SAG with microsomal antigen, but not with IF. It was concluded, that the microsomal antigen might be more active than IF. This observation could contribute to explane the higher incidence of parietal cell antibody than that of IF antibody in PA patients.
