[The humoral and cellular immunity indices of patients with long-term nonhealing stomach ulcers with the presence of Campylobacter pylori].

The authors relate the data on humoral and cellular immunity in patients with long nonhealing gastric ulcers. It has been shown that if these patients have Campylobacter pylori, there are no specific differences in the response of the immune system. During cicatrization, positive changes can be seen, namely an increase of T helper and decrease of suppressor activity of T lymphocytes together with a decline of the content of IgA and IgG.
