RESUMO
AIM: To study efficacy of Helicobacter pylori (Hp) eradication (different schemes) depending on the age of patients with Hp-associated duodenal ulcer (DU). MATERIAL AND METHODS: A total of 182 patients with Hp-associated exacerbated DU (101 males and 81 females) participated in the trial. The patients were divided into three groups according to their age: group 1 (18-39 years)--71 patients, group 2 (40-60 years)--71 patients, group 3 (61-74 years)--40 patients. Before and 4-6 weeks after treatment the patients were examined according to the standard scheme and with esophagogastroduodenoscopy (EGDS) including biopsy from the body and pyloric portion of the stomach. Seventy five patients received omeprasol+clarithromycin +moxicilline (scheme 1), 37 patients --eprasol+clarithromycin+tinidasol (scheme 2), 40 --eprasol+clarithromycin+furasolidon (scheme 3), 30 ---eprasol+clarithromycin+vicram (scheme 4). RESULTS: Hp dissemination in the pyloric stomach was independent of the age, nonatrophic and atrophic gastritis occurred with equal frequency. Contamination of the gastric body in the aged patients was moderate and mild. Atrophic gastritis incidence increased with age. After treatment according to scheme 1, Hp eradication was achieved in all the patients of group 3, 90%--group 1, 87%--group 2; according to scheme 2--100% patients of group 3, 90%--group 2 and 87%--group 1; according to scheme 3--all patients of groups 2 and 3, 90%--group 1; according to scheme 4--100% cases from groups 1 and 87% in group 2. CONCLUSION: Intensity of Hp dissemination in gastric mucosa does not depend on the age; it changes with deterioration of gastric mucosa atrophy and regress of acid production. Hp eradication efficacy in the same schemes of treatment is higher in presenile and senile patients who, therefore, can be treated with less doses of antibiotics.
