[Immunity in patients with peptic ulcer]

Factors of unspecific defense and immunological state were evaluated in 520 patients with ulcer disease. It was established that these patients revealed disorders of excessive release into the internal medium of the body of food antigens, in particular partially split proteins. The latter induce the immune response. An increase occurs of the production of secretion of IgA in the secretions, IgG in the blood, the T-system of immunity is inhibited, the complement consumption is increased. On the basis of obtained data the author proposes a hypothesis of ulcer formations, the essence of which is that food antigens entering the body causes sensibilization of the organism with a development of an immune-complex reaction of the Arthus phenomenon type in the gastroduodenal zone.
