Immunologic reactivity in patients with gastroduodenal ulcers

Immune system factors were studied in 158 patients with ulcer disease of the stomach and duodenum before and after different operative procedures. More pronounced alterations of immune reactivity as compared with the parameters in patients with noncomplicated ulcer disease were found which manifested themselves in decreased indices of cell immunity, activation of processes of autoallergization, inhibition of nonspecific factors of defense.
