Abstract
Background: There is not enough information about the course of the processes of lipid peroxidation-antioxidant defense in middle-aged men who are at risk of developing gastric cancer on the Correa cascade.
 Aims: To analyze of the processes of lipid peroxidation activity and antioxidant defense in men with chronic gastritis and chronic atrophic gastritis in combination with and without the presence of Helicobacter pylori.
 Materials and methods: 173 middle-aged men with an established diagnosis of chronic gastritis were examined, which were divided into 4 groups: group 1 ― patients with chronic gastritis without H. pylori (n=58), group 2 ― patients with chronic gastritis in combination with H. pylori (n=61), group 3 ― patients with chronic atrophic gastritis without H. pylori (n=28), group 4 ― patients with chronic atrophic gastritis in combination with H. pylori (n=26). Evaluation of the content of parameters of the lipid peroxidation system and the antioxidant components activity using spectrophotometric research methods was carried out. For statistical analysis, the software package Statistica 7.0 (Stat Soft, USA) was used. The study was conducted during 20132015.
 Results: Infection H. pylori with chronic and chronic atrophic gastritis accompanied by significant changes in the system of lipid peroxidation, and antioxidant defense components in the form of primary and accumulation of end products, insufficient activity of antioxidant enzymes ― superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase and reducing content of reduced glutathione. The use of an integrating factor to assess the severity of prooxidant activity confirms the development of antioxidant deficiency in patients of these groups.
 Conclusions: In patients with chronic and chronic atrophic gastritis, combined with H. Pylori infection, a more pronounced progression of oxidative stress reactions and a significant lack of antioxidant factors were found in comparison with patients with these forms of gastritis without H. pylori.

Summary
Недостаточно сведений о течении процессов липопероксидации-антиоксидантной защиты у мужчин среднего возраста, которые входят в группу риска развития онкологических заболеваний желудка по каскаду Корреа. Цель работы ― провести анализ активности процессов перекисного окисления липидов и антиоксидантной защиты у мужчин с хроническим гастритом и хроническим атрофическим гастритом в сочетании и без наличия Helicobacter рylori.
