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.

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 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.

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.

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.

The aim of the work. To study the effect of concomitant autoimmune thyroiditis (AIT) on the pathomorphological features of lesions of the esophageal mucosa in young patients with gastroesophageal reflux disease (GERD). Material and research methods. The study included 165 individuals. The contingent of the surveyed was students of Kharkov higher educational institutions. The main group consisted of 120 patients with a combined course of GERD and AIT, the comparison group included 65 individuals with an isolated GERD. The morphological form of the GERD was revealed during esophagogastroduodenoscopy (“Fuginon” system). A histomorphological study of the obtained biopsy material from the mucous membrane of the esophagus was carried out. Samples were studied on an Olympus BX-41 microscope. Morphometric study of the esophageal mucosa was performed using the Olympus DP-Soft. Research results. Histological examination of biopsy specimens revealed that the main pathomorphological signs of GERD in both groups were hyperplasia of the basal zone, lengthening of epithelial papillae, leukocyte infiltration, intercellular edema, expansion of the intercellular space, dystrophic changes, submucous fibrosis, the presence of severe inflammatory infiltration in the submucosal layer. Presence of concomitant AIT was associated with a statistically higher frequency of occurrence of certain signs: hyperplasia of the basal layer of the epithelium, elongation of the papillae, epithelial edema, expansion of the intercellular space, dystrophic changes in the epithelium (p<0.05). Conclusions. The presence of concomitant AIT in young patients with GERD does not affect the incidence of erosive GERD, but is associated with a significant increase in the severity of erosive esophagitis. The comorbid course of GERD and AIT in the student population is accompanied by a significant increase in the incidence and statistically significant intensification of the severity of hyperplasia of the basal layer of the epithelium, elongation of connective tissue papillae and leukocyte infiltration compared with isolated GERD

Cytokines are considered as “microendocrine system” due to the fact that they have a triple mechanism of action. First, they affect the cell-producer (autocrine effect); secondly, they influence neighboring (adjacent) cells (paracrine effect); thirdly, they affect the distant cells of organs and tissues (endocrine effect). Most cytokines have a wide range of biological activity, which is associated with their synthesis and secretion of various types of cells. Aim of study was to determine the role and prognostic values of tumor necrosis factor (TNF) α, interleukin (IL) 1β and IL-18 in young patients with autoimmune thyroiditis (AIT) and gastroesophageal reflux disease (GERD). Materials and methods. Study involved 83 patients (students) with GERD and AIT. The average age for the group was 22.1±2.11 years. The comparison group was represented by 30 patients of similar age with isolated GERD. The enzyme immunoassay was used to study the content of TNF-α, IL-1β and IL-18. Results. Upon evaluating the complaints of patients, it was found that the main manifestation of GERD was heartburn of varying severity, duration and frequency of occurrence. It has been shown that the course of GERD occurs against the background of the development of a systemic inflammatory reaction (increased synthesis of proinflammatory cytokines IL-1β and TNF-α), and also depends on the form of esophagitis: more pronounced in the erosive variant of the mucous membrane of the esophagus. At the same time, there was an increase in the synthesis of IL-18, which, with isolated GERD, is associated with a general inflammatory reaction, and with the addition of AIT, the inclusion of immune mechanisms. Relationship between the level of TNF-α in peripheral blood and the content of thyroid-stimulating hormone was studied. However, unlike the results of other scientists, the authors have not identified such a relationship.

Aim: to determine the state and role of autonomic reactivity and autonomic supply in patients with different manifestations of gastroesophageal reflux disease in combination with autoimmune thyroiditis through psychological testing by using a questionnaire of A.M. Vejn. Materials and methods. 87 patients with gastroesophageal reflux disease and autoimmune thyroiditis and 45 persons with an isolated gastroesophageal reflux disease were enrolled in the study. All the examined individuals were students. Results. It has been shown that the course of diseases is accompanied by a layering of clinical manifestations of autonomic dysfunction, which are more pronounced in cases of comorbidities. It has been found out that vegetative supply prevails in a number of indicators in the patients with an erosive form of gastroesophageal reflux disease. It has been proven that in almost all the cases of erosion (8 people - 72.7%), the individuals experienced some clinical manifestations of vegetative provision, such as general weakness, increased fatigue, lability of the pulse and blood pressure, and palpitation. At the same time, the “vegetative tail” was recorded only in a third (34.7%) of the studied without erosive lesions of the esophageal mucous membrane. The patients with an erosive form of the disease have a long period of experiencing some manifestations of autonomic dysfunction (up to 3 months) that considerably affects the quality of their life. Conclusions. Coupling of autoimmune thyroiditis and gastroesophageal reflux disease leads to the emergence of autonomic reactivity. Vegetative “supply” of the course of comorbidity between gastroesophageal reflux disease and autoimmune thyroiditis becomes more pronounced in the presence of an erosive process in the mucous membrane, which is also known as one of the factors of its possible manifestations.
