Antioxidant defense is considered in the context of a universal system, which, together with the components of the immune system, provides hemodynamic balance and antigenic homeostasis of the body, that is, the work of this system, represented by two practically independent links. The first line of the antioxidant system, the work of which is associated with the activity of superoxide dismutase, catalase, ceruloplasmin and a number of other enzymatic and non-enzymatic components, is considered an initial barrier, provides support at a constant controlled level of free radical oxidation. However, there is insufficient data in previous studies regarding the antioxidant defense system in patients with gastrointestinal disorders associated with thyroid disease. The purpose of the work was to establish the state of the antioxidant system in terms of total antioxidant activity and 8-isoprostane in young people with gastroesophageal reflux disease and autoimmune thyroiditis. Material and methods. The work involved 120 people with a combined course of gastroesophageal reflux disease and autoimmune thyroiditis at the age from 18 to 25 years. All patients had the same social status (students), which made it possible to equalize both physical and emotional stress, peak and stressful situations. Results and discussion. We examined the indicators of total antioxidant activity: the aggregate value of enzymes of the first level of the antioxidant system and 8-isoprostane, the level of the non-enzymatic link in antioxidant protection. These indicators depended on the morphological form of damage to the mucous membrane of the esophagus: they were more expressive in the erosive form of esophagitis. Thus, the combined course of gastroesophageal reflux disease and autoimmune thyroiditis is accompanied by changes in the indicators of the antioxidant system as a result of an active inflammatory process in the esophageal mucosa. There is a decrease in the total antioxidant activity, the first line of the antioxidant system, the value of which depends on morphological changes in the esophageal mucosa. Conclusion. An active inflammatory process in patients with gastroesophageal reflux disease and autoimmune thyroiditis leads to an increase in 8-isoprostane, an indicator of a non-enzymatic link in the antioxidant defense system

Objective — to determine the state of the antioxidant defense system by studying the total antioxidant activity and indicators of the glutathione system in young patients with gastroesophageal reflux disease (GERD) and autoimmune thyroiditis (AIT). Materials and methods. The study involved 120 patients with GERD and AIT (mean age — 21.9 ± 2.7 уears) and 45 subjects with isolated GERD (mean age — 21.2 ± 2.4 уears). All the investigated patients were the students of higher educational institutions. The general antioxidant activity was investigated as the aggregate indicator of the first phase of antioxidant defense and the state of the glutathione link of the antioxidant system (the activity of glutathione reductase, glutathione peroxidase and reduced glutathione). Results. It has been established that in patients with isolated GERD the total antioxidant activity of blood serum was significantly lower in comparison with the control group and was significantly suppressed with the addition of AIT. The decreased synthesis of glutathione reductase, glutathione peroxidase and reduced glutathione was reveled at the comorbid pathologies, as well as dependence of these parameters from the morphological forms of the esophageal mucous lesions: the most intensive alterations were observed  at the erosive form of the disease. Conclusions. The combination of GERD and AIT was accompanied by the changes in the antioxidant defense system parameters. This was manifested in the inhibition of the indicator of the total antioxidant activity and the enzymatic component of the second phase of the system — the glutathione link. These changes were dependent on the morphological form of the esophageal lesions.

Background. Despite numerous studies, the pathogenesis of gastroesophageal reflux disease remains unclear. Aim of research: assessment the activity of antioxidant defense system in young patients with GERD based on expression of biomarker associated with mitochondrial function. Material and methods. The study included 45 patients with gastroesophageal reflux disease. The examined contingent was presented by students age from 18 to 25 years. 20 healthy persons were included as control group. Levels of manganese superoxide dismutase were determined in blood serum of study persons with enzyme immunoassays (ELISA, Elabscience, USA). Statistical data processing by the Statistica Basic Academic 13 for Windows En local was made. Results. Gastroesophageal reflux disease in young patients is characterized by significantly increasing of manganese superoxide dismutase as compare to control group (7.1700 ng/ml vs 4.4720 ng/ml respectively, p<0.01). Presence of erosion in esophagus mucous doesn't accompanied by significant changes of evaluated parameter as compare with non-erosion form of disease in patients. Conclusion. The elevation in young patients with GERD the biomarker of mitohondrial antioxidant defense system we may speculate as adaptive response contributing to non-specific citoprotection. Taking to account the publishing facts about dual role of manganese superoxide dismutase it is necessary to monitoring antioxidant enzyme in patients with gastroesophageal reflux disease for prediction of possible complications and outcome.

The aim of this study is to establish the content of inflammation markers (tumour necrosis factor alpha and interleukin 18) and the index of total antioxidant activity in young patients with comorbidity between gastroesophageal reflux disease and autoimmune thyroiditis and to determine their dependence on morpho-histological changes in the oesophageal mucosa. Materials and methods. The study involved 182 students aged 18 to 25 years: 120 patients with comorbidity between gastroesophageal reflux disease and autoimmune thyroiditis, 42 those having an isolated course of autoimmune thyroiditis. The methodology included complex clinical, instrumental, immunological, statistical methods. Results. Determining the activity of proinflammatory cytokines has revealed their statistically significant increase. The level of these cytokines depends on morpho-histological changes in the mucous membrane and reaches the maximum during the erosive process. At the same time, the indicator of total antioxidant activity significantly decreases. In this case, the erosive form of the disease is accompanied by more expressive changes in this indicator. Conclusions. The inflammatory process in the oesophagus is accompanied by the activation of the pro-inflammatory segment of immunity against the background of the suppression of the antioxidant system, which is dependent on morphological changes in the oesophageal mucosa. These changes will contribute to the development of pathological apoptosis and the progression of nosologies.

The aim: To determine the state of total antioxidant activity and the content of the mitochondrial enzyme – manganese superoxide dismutase in students with gastroesophageal reflux disease (GERD) and autoimmune thyroiditis (AIT) comorbidity. Materials and methods: 120 patients with GERD and AIT, 45 patients with GERD and 42 patients with AIT were examined. The patients involved in the study were students. The international standardized GerdQ questionnaire was used. Total antioxidant activity and manganese superoxide dismutase levels were determined. Results: The study showed that comorbidity of GERD and AIT was accompanied with a significant increase in the frequency and intensity of heartburn, sleep disorders and the use of additional medications to relieve symptoms. Patients with GERD and AIT had significantly lower total antioxidant activity than patients with isolated GERD and isolated AIT. At the same time, the manganese superoxide dismutase level was significantly higher in group with comorbidity than in patients with isolated diseases. Conclusions: The presence of concomitant AIT in patients with GERD among the student population contributes to some deviations in the clinical characteristics, inhibition of total antioxidant activity and activation of manganese superoxide dismutase.

Background.Today infertile marriage is not only a serious medical, but also a socio-demographic and economic problem. Male factor contributes averagely to half of the cases of the disease in couples. Such factors as high levels of reactive oxygen species and oxidative stress have been reported to compromise the process of spermatogenesis and sperm function in men. Oxidative stress is a significant risk factor for male infertility. A pro-oxidant testicular environment may alter the expression profile of functional sperm proteins and result in poor sperm quality.Aims.To study the characteristics of the intensity of the processes of lipoperoxidation and antioxidant status in the ejaculate of men with different variants of spermograms.Materials and methods.We examined 69 men with primary infertility and 155 fertile men. The content of lipid peroxidation components and antioxidant protection was determined by spectrophotometric method.Results.The results of the study in men with infertility and asthenozoospermia showed decreased total antioxidant activity of sperm by 50 % and α-tocopherol by 52 %, and in men with infertility and oligozoospermia, decreased total antioxidant activity of sperm by 47 % and α-tocopherol by 41 %.Conclusions.The analysis indicates a change in the parameters of the system of lipid peroxidation – antioxidant defense system and confirms the development of oxidative stress in them. Depending on the pathological state of the ejaculate in men of reproductive age, lipid peroxidation processes have their own characteristics. In men with oligozoospermia, peroxidation processes occur more intensively. Activation of lipid peroxidation – antioxidant defense system processes can be both a consequence and a cause of various metabolic changes in the human body.

Aim: to establish the content and role of Klotho protein in the pathogenesis of gastroesophageal reflux disease, which occurs against the background of autoimmune inflammation in young people. Materials and methods. Three groups of patients were involved in the study: with the gastroesophageal reflux disease (GERD ) and autoimmune thyroiditis (AIT ) (120 persons), isolated GERD (45) and AIT (42) aged 18 to 25 years, of the same sex and duration of the disease. The content of Klotho protein was determined in the serum by ELISA, Elabscience reagents (ELISA, USA). Results. Significant increase in Klotho protein was detected in patients with GERD and especially in its combination with AIT relative to the control. Content of Klotho protein did not correlate with the morphological form of the disease and its duration. In patients with isolated AIT , Klotho protein level did not have a significant difference with control group. Conclusion. The GERD and its combination with AIT in young people are accompanied by an increase in Klotho protein content, as a result of the presence of an active inflammatory process in the esophagus mucosa and its stimulating effect on antioxidant defense processes.

Objective — to establish changes in indicators of the antioxidant defence system, taking into account the morphological form of the esophageal mucosa lesions in patients with gastroesophageal reflux disease (GERD), occurring against the background of autoimmune thyroiditis (AIT). Materials and methods. The study involved 120 students with GERD and AIT, aged 18 to 25 years; from them 93 (77.5 %) females and 27 (22.5 %) males. The disease duration did nit exceed 3 years. Fibrogastroduodenoscopic examination has shown an erosive form of gastroesophageal reflux disease in 34 patients (28.3 %) and non‑erosive form of the disease was in 86 cases (71.7 %). Indicators of the total antioxidant activity of glutathione peroxidase and mitochondrial manganese superoxide dismutase were examined. Results. A decrease in the total indicator of the total antioxidant activity was established, which was estimated as the failure of the first phase of the antioxidant defence system. At the same time, an increase in the activity of manganese superoxide dismutase and a decrease in the production of glutathione peroxidase were noted. The levels of total antioxidant activity and glutathione peroxidase correlated with morphological changes in the esophageal mucosa: the presence of the erosive form of the disease had a greater impact on the changes in these parameters. Conclusions. The combined course of gastroesophageal reflux disease and autoimmune thyroiditis in students was accompanied by a decrease in the indicators of total antioxidant activity and glutathione peroxidase and an increase in the activity of manganese superoxide dismutase. The presence of erosions in the esophageal mucosa had a greater impact on the changes in the parameters of total antioxidant activity and glutathione peroxidase.

Introduction. In recent years, there has been an increase in the prevalence of gastroesophageal reflux disease and autoimmune thyroiditis in young people. This is associated with a hereditary predisposition, viral diseases, which are often recorded in children's and adolescent groups, the unreasonable use of a large number of drugs, as well as the influence of various negative environmental factors, instability of the autonomic nervous system, eating disorders, the presence of bad habits, chronic stress and others. The aim of the work was to investigate the state of total antioxidant status and the content of biomarkers of the second phase of detoxification of xenobiotics - manganese superoxide dismutase and glutathione peroxidase in young people with gastroesophageal reflux disease and autoimmune thyroiditis. Materials and methods. To achieve this goal, 120 patients with a combined course of gastroesophageal reflux disease (GERD) and autoimmune thyroiditis (AIT) were examined, which made up the main group and two comparison groups: with isolated GERD (45 people) and AIT (42 patients). All patients were students of various universities and were between the ages of 18 and 25. Duration of the disease did not exceed 3 years. The total antioxidant status as an indicator of the first phase of defense and the levels of mitochondrial manganese superoxide dismutase and glutathione peroxidase – the second phase of antioxidant defense was determined. Results. The study showed that in all surveyed groups there was a decrease of total antioxidant status, which characterizes the first phase of the antioxidant defense system. Changes in the first phase of antioxidant defense affect the indicators of the second level of the system, which became the basis for studying the activity of mitochondrial manganese superoxide dismutase. Thus, the value of this indicator in all examined individuals exceeded the norm, which confirmed the inclusion of the second controlling phase of antioxidant system into the pathological process. At the same time, an increase inhibition of the glutathione defense link, the second phase of xenobiotic detoxification, were diagnosed. Conclusions. Negative changes occur in the enzyme system of the first line of antioxidant system in patients with GERD and AIT which may be the result of an unfavorable autoimmune background. Control over the work of antioxidant system moves to the second phase of the system, manifested by an increase in the content of mitochondrial manganese superoxide dismutase and inhibition of the activity of glutathione peroxidase in patients with a combination of GERD and AIT.

The aim of the study: to assess the role of caspase-1 and IL-18 in the implementation of the inflammatory response in young patients with autoimmune thyroiditis (AIT) associated with gastroesophageal reflux disease (GERD). Materials and methods. The study was conducted in two groups of patients homogeneous by gender and age. The first group included 42 patients with an isolated AIT and the second group – 120 patients with a comorbid course of AIT and GERD. The contingent of the surveyed was students. Median age was from 18 to 25 years: 23.1±1.2 years in group with isolated AIT and 21.9±2.7 years in group with combined pathology. The activity of caspase-1 was determined using “Elabscience” kits, USA (China) by immunoassay method. The content of IL-18 was investigated using commercial kits “Bender MedSystems GmbH” (Austria) according to the proposed methods by immunoassay method. Statistical data processing was carried out using the local universal software package Statistica Basic Academic 13 for Windows En Local. Methods of non-parametric statistics were used: Kruskal-Wallis test, median test, Mann-Whitney test. Results. It has been found that caspase-1 is activated in patients both in the isolated course of AIT and in its combination with GERD. At the same time, a significant increasing in the synthesis of IL-18 was established, which has pro-inflammatory and autoimmune effects. Re-examination after 2 months of caspase-1 and IL-18 in examined persons determined decreasing their levels, but control results were not achieved. Conclusion. In young patients, the combination of GERD and AIT, as well as an isolated AIT is accompanied by an increasing the levels of caspase-1 and IL-18 in blood serum related to inflammatory process in the thyroid gland and esophageal mucosa with autoimmune component. These biomarkers may reflect the severity of clinical course of diseases and serve as prognostic indicator of outcome in case of comorbidity.
