[Dependence of clinical course and outcome of chronic duodenitis on some features of its pathogenesis].

The effects of acid, infectious (Helicobacter pylori) and neuroendocrine factors on the course and outcome of chronic duodenitis were studied in 57 patients aged 15-35 years. Within 5-year follow-up ulcer emerged in 26% of duodenitis patients. Ulceration occurred as a result of high acid production in the basal and stimulated phases, contamination of pyloric-antral mucosa with Helicobacter pylori, unbalance of serum hormones T4, TTH, FSH, ACTH. In risk of ulcerogenesis there were psychological shifts with appearance of pathological reaction to the disease. Consideration of pathogenetic specificity of different duodenitis forms and basing on objective and subjective criteria allow identification of ulcer risk group and early start of optimal therapy.
