Regularities of the Oxidative Stress Processes in Case of Bleedings from Acute and Chronic Ulcers of the Stomach and Duodenum

The main aim of the study was to determine ways of improving the results of treating patients with ulcer bleeding of various nature and severity. It was provided by the system study of free radical processes and evaluation of the effectiveness of timely antioxidant therapy. Material and methods. The study included 153 patients aged 18-94 years with acute and chronic gastric and duodenal ulcers complicated by gastroduodenal bleeding. Patients were divided into two groups: group I (experimental group) included 62 patients who received antioxidative therapy with reamberin as a part of the basic therapy; and group II (control group) included 91 patients who received standard therapy. Various parameters of Free Radical Processes (FRP) were studied in dynamics in all patients. Results. We revealed the significance of oxidative stress on the first day of hospitalization in patients with gastrointestinal ulcerous bleeding of various character and severity. It was discovered mostly in severe patients with acute Gastroduodenal Ulcerous Bleeding (GDUB). In case of mild gastrointestinal ulcerous bleeding, oxidative stress disorders affected an oxygen stage of oxidative stress and represented themselves adaptive compensatory mechanisms. As the severity of the disease increased, intensification of an oxidant stress was manifested by a decrease in oxygen activity and an increase in lipid imbalance. Imbalance in free radical processes continued for a long time until discharge of patients from the hospital. The data obtained claimed to be the basis for recommendation to include antioxidant energy-conserving therapy in the complex of therapeutic measures in the earliest possible terms. We found out an efficacy of using succinic acid therapy with reamberin in patients with gastrointestinal bleeding. Positive effect of succinic acid on the markers of oxidative stress was confirmed by improvement in the disease pattern and success of the treatment.
