[The status of general and local humoral immunity in patients with peptic ulcer and chronic gastroduodenitis].

The content of secretory immunoglobulins A and serum immunoglobulins A, M, G, D in the blood serum and biological. fluids (saliva, gastric juice and duodenal contents) was examined in 108 patients with gastric and duodenal ulcer and in 68 patients with chronic gastroduodenitis. The obtained data evidence tense states of the general and local humoral immunity in all patients with gastric and duodenal ulcer and chronic gastroduodenitis. Monotypical changes in patients with diseases of the gastroduodenal zone, apparently, reflect the participation of the immunological component of the ulcerogenic situation already at the stage of preulcer condition.
