Abstract: © 2018 Undersea & Hyperbaric Medical Society, Inc. Taking into consideration that a high concentration of oxygen can express toxic effects due to production of reactive oxygen species (ROS), the aim of our investigation was to establish the influence of hyperbaric oxygenation on oxidative stress parameters and antioxidant enzymes in patients with diabetes mellitus (DM) type 2. Investigation included 50 patients with DM type 2 divided into two groups. The first group consisted of 25 patients, mean age 70 years, mean duration of illness 12 years and without manifest peripheral vascular complications (Wagner 0). The second group consisted of 25 patients, mean age 74 years, mean duration of illness 17 years and with manifest peripheral vascular complications (Wagner 1-5). All patients underwent the same therapeutic protocol, which included 10 hyperbaric oxygenation therapies, once a day for a duration of 60 minutes, with an average partial oxygen pressure of 1.7 atmospheres absolute (ATA). In blood samples the following parameters of redox balance were determined: Levels of nitrites (NO2-), index of lipid peroxidation (TBARS), superoxide anion radical (O2-), hydrogen peroxide (H2O2) and antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT). Our results clearly show that hyperbaric oxygen (HBO2) therapy does not have a pro-oxidative effect. Additionally, it seems that this procedure strongly mobilized the antioxidant enzyme system, thus improving defense from oxidative damage. All significant data are marked as P<0.05. Our results have shown that in terms of ROS production, HBO2 can be safe to use in patients suffering from DM type 2 with or without vascular complications.
