The current data suggest that Helicobacter pylori infection and type 2 diabetes mellitus may affect the state of nitric oxide system, which significantly influences stomach functioning. The aim of the research was to study the state of nitric oxide system in patients with Helicobacter pylori-associated chronic gastritis and concomitant type 2 diabetes mellitus, and to investigate the potential of eupatilin in its correction. 172 patients with confirmed chronic gastritis were enrolled into the
... enrolled into the study. They were divided into 4 groups: І (n=71) included individuals with Helicobacter pylori-positive chronic gastritis and type 2 diabetes mellitus; ІІ (n=21) included patients with Helicobacter pylori-negative chronic gastritis and type 2 diabetes mellitus; ІІІ (n=48) included patients with Helicobacter pylori-positive chronic gastritis without type 2 diabetes mellitus; IV (n=32) was made up with individuals having Helicobacter pylori-negative chronic gastritis without type 2 diabetes mellitus. According to prescribed therapeutic schemes the patients of groups І and ІІІ were additionally subdivided into the following subgroups: groups I-A (n=35) and III-A (n=24) underwent anti-Helicobacter therapy, groups I-В (n=36) and III-B (n=24) were prescribed to receive anti-Helicobacter therapy and eupatilin. Anti-Helicobacter therapy included pantoprazole 40 mg, amoxicillin 1000 mg and clarithromycin 500 mg bid for 10 days. The patients received Eupatilin as an active agent of Stilen preparation, which contains 0.48 – 1.44 mg of eupatilin, tid for 28 days. Nitrites content and activity of inducible and constitutional nitric oxide synthases were analyzed in blood serum before the treatment and on the 28th day after the therapy completed. The patients of group I before the treatment were found to have an increase of nitrites level in 1.4 times, inducible nitric oxide synthase in 1.5 times higher in comparison to the patients of group II. An activity of constitutional nitric oxide synthase in patients with chronic gastritis and type 2 diabetes mellitus was found to be decreased regardless the Helicobacter pylori-status in 2.3 and 2.7 times in comparison to the patients of groups III and IV respectively. Eupatilin prescription promoted Helicobacter therapy eradication and treatment outcomes through nitrites decrease in 1.5 times, reduction of inducible nitric oxide synthase activity in 1.2 times, and growth of constitutional nitric oxide synthase in1.2 times in patients of I-B group in comparison to group I-A. Combined anti-Helicobacter therapy with eupatilin promotes successful Helicobacter pylori eradication, which was 6.2% higher in patients of I-B group than in I-A group. Conclusions: Helicobacter pylori-associated chronic gastritis in patients with type 2 diabetes mellitus is followed by rise of nitrites, inducible nitric oxide synthase activity and simultaneous decline of constitutional nitric oxide synthase in blood serum. Eupatilin prescription as a component of integrated anti-Helicobacter therapy increases the efficacy of Helicobacter pylori eradication and improves the state of nitric oxide-system due to its anti-inflammatory, antioxidant and cytoprotective properties.
