Дорогие коллеги, читатели журнала «Экспериментальная и клиническая гастроэнтерология»!
Более чем за 25 летнюю историю издания журнала «Экспериментальная и клиническая гастроэнтерология», очевидно, впервые среди терапевтических изданий ежегодно первый номер журнала посвящается детской гастроэнтерологии. Такой паритет сохраняется на протяжении почти десяти лет и обусловлен постулатом, что все болезни «родом из детства».
Такая практика обоюдополезна. Так, благодаря педиатрическим публикациям в журнале для врачей взрослой практики, интернисты получили возможность овладения новейшей информацией в области детской гастроэнтерологии, гепатологии и смежных специальностей, а врачи- педиатры, в свою очередь, обогащают свои знания в области внедрения у взрослых новых технологий, лекарственных средств, лечебной тактики и др. Особую значимость такое сотрудничество приобретает в свете подготовки врачей общей практики, когда перед врачами – терапевтами стоит задача освоения педиатрических дисциплин, в том числе и в области детской гастроэнтерологии. Учитывая высокую степень коморбидности болезней, не позволяющую выделить основную нозологию среди конкурирующих диагнозов, в публикациях участвуют врачи-педиатры самых различных специальностей: педиатры, генетики, морфологи, физиологи. и др. Настоящий выпуск журнала юбилейный, посвящен 30-ти летию кафедры педиатрии с инфекционными болезнями у детей «Российского национального исследовательского университета им. Н. И. Пирогова. Сотрудниками и учениками кафедры, работающими в различных регионах России (Саратов, Санкт-Петербург, Краснодар, Архангельск и др.) рассматриваются вопросы этиологии, патогенеза, клиники, диагностики, профилактики и лечения заболеваний пищеварительного тракта у детей.
Открывает наш номер фундаментальная Актовая речь величайшего физиолога Коротько Геннадия Феодосьевича, посвященная пептидомическому анализу ауто- и инрагастрального протеолиза грудного молока в которой рассматриваются не только в роли трофотропных участников деградации его нутриентов, но и образования протеазами молока функционально полипотентных регуляторных пептидов с характерным изменением их числа и содержания в динамике кормления ребенка и сроков гестации.
В передовой статье описаны причины патоморфоза взглядов и понятий на микробиоту человека. Внедрение новых понятий на уровне молекулярной генетики и биологии позволило по-новому подойти к терапевтической коррекции микробиоты кишечника.
В разделе, посвященном клиническим аспектам гастроэнтерологии представлено восемь статей, где описаны оригинальные исследования в области морфо-физиологии, экологии, а также нутритивного статуса и физического развития детей, родившихся от матерей с обменными нарушениями, или проживающими в регионах с неблагополучными условиями окружающей среды. Несомненный интерес и повод для дискуссии представляет статья Боковой Т. А. «Клинико-патогенетические взаимосвязи между функциональным состоянием поджелудочной железы и основными компонентами метаболического синдрома», посвященная оригинальным исследованиям в области изучения патогенетических механизмов, где показано, что при формировании метаболического синдрома, резко снижается функциональная способность поджелудочной железы у детей с ожирением, что характеризует срыв компенсаторных возможностей последней с развитием хронического панкреатита.
Особый интерес вызывают представленные группой авторов данные о физическом развитии новорожденных, родившихся от матерей с различными нарушениями углеводного обмена, где убедительно показано, что наиболее значимые осложнения и нарушения нутритивного статуса выявляются у детей, где вовремя беремености формировался гестационный сахарный диабет, не, как ожидалось, от матерей, страдающих сахарным диабетом I типа. Авторы отмечают, что именно гестационный диабет (транзиторный диабет беременых) дает нам когорту детей с высокой степенью риска развития в будущем метаболических нарушений вплоть до инсулин зависимого сахарного диабета.
Хорошо подготовлены и широко представлены в этом журнале обзоры литературы. Среди них дискуссионный характер носит статья посвященная, пожалуй, самой актуальной проблеме детской гастроэнтерологии – язвенной болезни. В статье представлен драматизм столкновения различных теорий возникновения язвенной болезни. Особое внимание уделено язвенной болезни у детей и ее хирургическим аспектам, роли Helicobacter pylori в этиологии этого заболевания. Результаты, представленные в статье, позволяют понять на основании каких достижений медицинской практики врачам удалось улучшить качество жизни больных с язвенной болезнью и значительно снизить их инвалидизацию. но и изложена позиция автора о язвенной болезни, как системном заболевании. Насколько убедительны эти суждения следует оценить читателям.
Привлекает внимание обзор, посвященный паразитарным инвазиям билиарного тракта у детей, где развеян миф о так называемом «лямблиозном холецистите». Показано, что лямблии, в отличии от других паразитарных инвазий (описторхоз, токсокороз), никакого отношения к развитию воспалительного процесса в желчном пузыре не имеют, в связи с чем термин «ляблиозный холецистит» неправомочен. Превосходно подготовлены и иллюстрированы клинические наблюдения, в частности, случай лангергансоклеточного гистиоцитоза – редкого гранулематозно-пролиферативного заболевания у ребенка с гемоколитом.
Безусловно полезен и интересен обзор, посвященный глубокому анализу современных представлений об особенностях течения, диагностики и лечения столь редкого (орфанного) заболевания, как синдром Лойса-Дитца, выявление которого стало возможно лишь при использовании новых молекулярно-генетических технологий – NGS (секвенирования нового поколения). Показана значимость установления диагноза методом таргентного секвенирования ДНК, позволяющего выделить мутацию у детей со схожими фенотипическими проявлениями (арахнодактилией, синдромом Марфана и др.), но не часто диагностируемыми в детском возрасте. Авторы и составители настоящего юбилейного выпуска журнала «Экспериментальная и клиническая гастроэнтерология» сами по себе являются ведущими гастроэнтерологами страны и искренне надеются, что представленные материалы окажутся интересными и полезными читательской аудитории, а также будут способствовать повышению профессионализма не только педиатров, но также интернистов и гастроэнтерологов.
С искренним уважением и благодарностью

Abstract:The relevance of milk-feeding of babies, the importance of not only the composition and properties of breast milk, but also the technology of enzymatic degradation of its nutrients are cosidered In the Assembly speech. First, it is produced according to the type of its own digestion by hydrolases of the digestive glands and the small intestine of the infant, the complex of which is formed antenatally and called the starting multienzyme digestive potential in the newborn child. Its quantitative characterization is possible by determining the main digestive hydrolases in the amniotic fl uid, in the blood of the umbilical cord and in the gastric aspirate of the infant. The expression of this potential in the point system is proposed. With incomplete gestation, the digestive potential is reduced. Secondly, hydrolysis of breast milk nutrients is carried out by its own hydrolases in the autolytic type of digestion. The dynamics of secretion of hydrolases by the mammary glands of healthy women during one year of lactation was studied. The quantitative dependence of the hydrolase secretion on its value in the fi rst lactation month is described with a general tendency to a decrease in the hydrolase content in milk with an increase in the monthly lactation period, and the dependence of the secretion of enzymes by the mammary glands from the age of the pregnant women. The dynamic convergence of the multienzyme digestive potentials of the child's digestion system and the mother's milk it takes is relevant in lactotrophy. Based on the results of peptidic analysis of auto-and inragastral proteolysis of breast milk, milk hydrolases are not only considered as trophotropic participants in the degradation of its nutrients, but also in formation of by milk proteases functionally multipotent regulatory peptides with a characteristic change in their number and content in the dynamics of infant feeding and timing of gestation.

Abstract:Microbiota plays a key role in the physiology and maintenance of homeostasis of the human body. The importance belongs to the processes of the formation of the intestinal microbiota, starting in utero, and the child continues to receive the mother’s microfl ora during childbirth and breastfeeding. The results of molecular genetic studies indicate that the most intensive process of microbial colonization in infant is associated with features of feeding. The main factor in maintaining the stability and resistance of normal biota is microbial autometabiolites. Considered the most promising probiotic biotechnology and development metabolic of probiotics (metabiotics) probiotics in combination with Prebiotics (synbiotics). Understanding the processes of formation of intestinal microfl ora allows you to develop eff ective methods of prevention and correction micro-ecological and motor disorders in the age aspect.

Keywords: ecology, children and teenagers from Krasnodar region
Abstract:The aim of the research is to study the infl uence of diff erent pollution levels on clinical and epidemiologic aspects in erosive ulcerous diseases of gastric mucosa and duodenum in children and teenagers. Materials and methods: the research is carried out in Krasnodar region and it consists of two stages. At fi rst stage 47 territories of Krasnodar region are ecologically assessed, at second stage epidemiologic rate (prevalence and sickness rate) of erosive ulcerous diseases of gastric mucosa and duodenum in children and teenagers in Krasnodar region are studied according to data regarding visits to the health care centers and calls of the special medical crews against the ecological condition of the territory. Results. Ecological state of the territories in Krasnodar region diff ers as per anthropogenic load intensity. Low levels of pollution are indicative for regions with favorable ecology (15 regions), medium levels — for regions with conditional favorable ecology (17 regions), and high levels of pollution — for regions with unfavorable ecology (15 regions). There is a numeric dependency between number of children and teenagers visiting health care centers and the level of anthropogenic pollution of regions where they live. The number of children visiting health care centers in connection with erosive ulcerous diseases of gastric mucosa and duodenum is 2.3 times higher, of teenagers — 1.5 times higher against number of patients from regions with favorable ecology.

Keywords: children, cholelithiasis, overweight, cytolysis, cholestasis
Abstract:The purpose of the study was to reveal the frequency and characteristics of the course of the cholelithiasis on the basis of studying the histories of children hospitalized in the Department of Gastroenterology of the State Children’s Hospital No. 9 named after GN Speransky in 2016–2017. Materials and methods: 3200 case histories of children were analyzed; in 32 children, cholelithiasis was diagnosed, among them 11 boys and 21 girls aged 1–9 months to 17 years 8 months. Anthropometric data, family history, duration of the disease, presence of abdominalgia, episodes of a sharp decrease in body weight were evaluated. Laboratory and instrumental studies were conducted. Results: cholelithiasis occurs in 10% of children with digestive tract diseases, mostly in girls, about half of patients had normal body weight and heredity of cholelithiasis, and in every fi fth child, relatives suff ered from excessive body weight. In 28% of cases, cytolysis syndrome (> 10 norms) and cholestasis (> 3 norms) were detected, clinical symptoms of cholelithiasis were noted within 3 months, in half of the children developmental abnormalities and a suspension in the gallbladder cavity were diagnosed. 25% of adolescent girls deliberately reduced body weight. Conclusion: when detecting stones in the gallbladder, it is necessary to determine the indicators of liver and pancreas function, despite the possible absence of complaints of pain in the right hypochondrium.

Keywords: metabolic syndrome, obesity, children, pancreas, postprandial reaction, thyroid, carbohydrate metabolism, lipid metabolism, fatty liver disease
Abstract:Relevance. Pancreas refers to the organs, the functional state of which is the most signifi cant factor in the development of hormonal and metabolic disorders. Objective: to study the morphofunctional state of the pancreas in children with obesity and to evaluate its relationship with the main components of the metabolic syndrome (MS). Materials and methods. Surveyed 483 children with obesity from 6 to 16 years. Group I — 237 children with obesity complicated by MS, Group II — 246 children with obesity without signs of MS. A complex of clinical, laboratory and instrumental methods of examination was carried out using standard methods; 90 children (60 children from group I and 30 children from group II) underwent an ultrasound examination of the pancreas (RV) with the determination of the postprandial reaction. The results of the study. In 94.9% of children I gr. and 89.8% of children II g. various changes in the structure of the pancreas were revealed: an increase in acoustic density (77.6% and 63.8%, respectively), the presence of hyperechoic inclusions in the parenchyma (86.1% and 82.1%, respectively). The total size of the pancreas on an empty stomach in children in I group exceeded the normative fi gures and was more than that of II gr. (59.85 ± 6.27 mm and 53.11 ± 7.62 mm, respectively, p <0.05). After food stimulation, this indicator amounted to 65.75 ± 7.41 mm in I gr., and about 59.64 ± 5.40mm (p <0.05) in II gr. Exclusively in I gr. (16.7%) postprandial reaction was absent or was sharply reduced (less than 5%). The level of glucose, insulin, C-peptide and HOMA-IR index was higher than in the compared subgroups, and signifi cantly exceeded the standard indicators in children with a reduced postprandial reaction. Triglyceride levels were also signifi cantly higher, and high-density lipoproteins were lower than in other subgroups. In children with non-alcoholic fatty liver disease, the total size of the pancreas on an empty stomach was larger than in children with a normal organ structure (p <0.001), and the postprandial reaction of the pancreas was signifi cantly lower: 7.5% (6.8–8.5%), respectively and 10.4% (11.8–17.9%) (p <0.01). With an increase in the thyroid gland, the size of the pancreas head on an empty stomach was signifi cantly larger than in children with a normal thyroid volume. A decrease in the postprandial response of less than 5% was observed in 33.3% of children with an enlarged thyroid, and in 16.7% of children with normal thyroid size (p <0.05), the normal response of the pancreas (more than 15%) was determined solely in children with not Thyroid gland (11.9%). Findings. Most obese children (up to 95%), regardless of the presence of MS, revealed structural and functional changes in the pancreas. A signifi cant decrease in the postprandial pancreatic response was recorded in children with MS. Only in children with MS (16.7%), the postprandial pancreatic reaction was absent or was sharply reduced (less than 5%), which should be considered as a clinical sign of impaired adaptive capacity of the pancreas against the background of a latent chronic infl ammatory process. The relationship between carbohydrate metabolism and lipid metabolism with the total size and size of the pancreatic head on an empty stomach and after food load has been established. Children with NAFLD have a higher risk of developing CP. A close relationship between the morphofunctional state of the pancreas and thyroids has been established.

Keywords: oxidative stress, blood antioxidant ability, metabolic active obesity, metabolic healthy obesity, metabolic syndrome, atherogenic disorders, chronic infl ammation, children, adolescents, schoolchildren
Abstract:The purpose of the study is to assess the level of oxidative stress and impaired blood antioxidant capacity in children and adolescents with metabolic active obesity and other components of the metabolic syndrome. Materials and methods. Surveyed 102 children and adolescents aged 10 to 15 years with obesity. According to the results of clinical and laboratory examinations, groups were identifi ed depending on the presence of metabolic disorders: metabolic active obesity (MAO) and metabolically healthy obesity (MHO). The comparison group consisted of 230 schoolchildren of secondary educational institutions of the city of Arkhangelsk. Results. When comparing groups with MAO, MHO and children without metabolic disorders, it was found that the highest average level of total peroxide (PPS) is observed in the group with MAO, the lowest in the comparison group (<0.001). Among the average indicators of the general antioxidant system (GAS), on the contrary, the lowest value is observed in the group with MAO, the highest — in the comparison group, in children and adolescents with MLO — intermediate values of AOS. The average levels of the studied parameters of proatherogenic metabolic disorders (uric acid (UA), lipid spectrum, glucose, C — reactive protein, blood pressure, HOMA index, insulin) were signifi cantly higher in the group with MAO, except for the average level of high density lipoprotein cholesterol (HDL cholesterol), which is signifi cantly lower. Conclusion. In children and adolescents with MAO, changes in the classic indicators of atherogenic disorders (blood lipid spectrum, blood pressure, insulin resistance, hyperinsulinemia, chronic infl ammation) and high levels of oxidative stress are found, along with a decrease in the activity of the antioxidant system, which may have not only pathogenetic signifi cance, but also reveals promising areas for the prevention and treatment of atherogenic disorders.

Keywords: diabetes, pregnancy, newborns, physical development
Abstract:Introduction: Every year, 50–150 thousand babies are born to mothers with diabetes. Currently, there is no doubt that the condition of newborns born in mothers with diabetes requires special attention because of the increased risk of developing diseases of the respiratory tract, cardiovascular system, brain, kidneys etc. Purpose: Evaluation of various types of diabetes during pregnancy in mothers infl uence at the physical development of newborn children. Materials and methods: 350 full-term babies from mothers with diabetes mellitus, which was born at the N. E. Bauman Hospital which is specialized in the management of such pregnant women. Assessment of the physical development of children was carried out according to WHO standards (2006) using the WHO Anthro program. Comparative analysis of indicators of children in diff erent groups using Student t-criterion. We used the program Statistica 10. Results: The body mass of 350 examined newborns varied within 1590–4710 g, on average, amounted to 3421.1 ± 543.99 g. There were 67 (19.1%) children who had a body weight less than 3000g and 46 (13.1%) more than 4000 g. Growth values of 350 newborns ranged from 40–57 cm, on average, amounted to 51.21 ± 2.54 cm. We analyzed the indicators of physical development of children in all groups depending on gender. We carried out a comparative analysis of the parameters of body mass (m), body length (H), BMI and the ratio of body mass to body length in the experimental and control groups. Conclusion: children born to mothers with various types of diabetes have a higher height, weight to body length ratio, WAZ and HAZ indicators than newborns from mothers with normal glycemia. The weight and height of newborns in the groups of GDM and DM-2 did not diff er signifi cantly among themselves. The shortest and most lightweight children are born to mothers with type 1 diabetes,

Keywords: caries, celiac disease, bone metabolism indicators
Abstract:The aim of this study was to assess the cariesogenic situation in the oral cavity and bone metabolism in children with celiac disease. It is established that in children with early identifi ed with celiac disease, indicators of a cariogenic situation of the oral cavity and the indicators of bone metabolism signifi cantly better than children with later identifi ed with celiac disease. The violation of bone metabolism and a high risk of caries in children with celiac disease were found, and therefore early diagnosis of the disease and compliance with the diet are necessary. And in the treatment of a dentist, a special role is played by medical examination and preventive measures.

Keywords:intestinal microbiocenosis, NAFLD, short-chain fatty acids, rifaximin, psyllium
Abstract:Aim of investigation: to study the content and qualitative profi le of shot-chain fatty acids in feces and blood serum in patients with NAFLD of diff erent stages as indicators of intestinal microbiocenosis status and systemic lipid metabolism, and to evaluate the eff ectiveness of course antibacterial (rifaximin) and prebiotic (psyllium) therapy in the period of 6 months for the correction of gut microbiocenosis disorders. Material and methods: The survey included 115 patients (82 (71,3%) men, 33 (28,7%) women) with NAFLD of diff erent stages (steatosis — 40 people, nonalcoholic steatohepatitis (NASH) of minimal activity — 30 people, NASH of moderate activity — 30 people, liver cirrhosis class A Child-Pugh — 15 people) at the average age of 51,83±8,48 years old. All the patients were examined by research of short-chain fatty acids (SCFA) using gas-liquid chromatographic analysis in various biological substrates (blood serum and feces). According to the management scheme, the patients with NAFLD were divided into 3 groups. The fi rst group of 30 people (on the background of lifestyle modifi cation) received a 6-month intake of psyllium. The second group of 35 people in addition to lifestyle modifi cation received a 7-day course of rifaximin (7 — days/800 mg/d) and psyllium during the period of observation (6 months). The third group of 35 people received standard therapy of NAFLD without pharmacotherapy aimed to correction of gut microbiocenosis disorders. In the course of treatment the frequency and severity of clinical manifestations of intestinal bacterial overgrowth syndrome (SIBO) reduced in patients of groups 1 and 2 (in group 1 the complaints on abdominal pain and fl atulence decreased by 11%, in group 2 — by 37%, the normalization of stool occurred in both groups), SIBO was not detected according to the results of the hydrogen breath test with lactulose, the level of total endotoxin was determined within normal values. Negative dynamics was noted in group 3: the increase in the number of complaints of abdominal pain by 16%, fl atulence and unstable stool — by 10%, the frequency of registration of SIBO increased by 20%, increased level of total endotoxin was detected in 5.7% of patients. Results. The absolute concentration of SCFA in feces in patients with NAFLD (steatosis) is reduced, in patients with NASH of minimal activity, NASH of moderate activity and liver cirrhosis is increased, in the profi le of C2-C4 acids there was the increase in the share of propionic and butyric acids and the decline in the share of acetic acid, the anaerobic index (AI) defl ected in the region of strongly negative values, the total relative content of isoacids increased in all groups of patients, worsening with the severity of the pathological process (at normal Σ(С2-С6)=10.51±2.50 mg/g, С2=0.634±0.004, С3=0.189±0.001, С4=0.176±0.004, АI= –0.576(±0.012), Σ(isoСn)=0.068±0.004). The obtained results indicate marked changes in the qualitative and quantitative composition of the microfl ora, the decrease in the number and activity of obligate microorganisms and the increase in facultative and residual anaerobic bacteria. These changes in the microbial landscape lead to the marked disorders in the intestinal phase of lipid metabolism. The absolute concentration of SCFA in serum in patients with NAFLD (steatosis) is reduced, in patients with NASH of minimal activity, NASH of moderate activity is increased, in the profi le of C2-C4 acids there is the decrease in the share of propionic acid and the increase in the share of butyric acid, most pronounced in steatosis and NASH of minimal activity. In patients with liver cirrhosis, the absolute concentration of SCFA in serum is increased, in the profi le of C2-C4 acids, the share of acetic acid is sharply reduced with an increase in the share of propionic and butyric acids and the total relative content of isoacids. The content of caproic and isocaproic acids is increased in all groups (at normal Σ (C2-C6)=0.195±0.011 mg/g, C2=0.902±0.006, C3=0.071±0.004, C4 = 0.027±0.002, Σ (isoCn)=0.040±0.007, isoC6+C6=0.025±0.004). This fact can be explained by the changes in the functional state of hepatocytes, and, consequently, in the metabolic function of the liver (in particular with respect to lipid metabolism). The clinical effi cacy of therapeutic management with the use of drugs aimed at the relief of the intestinal microfl ora disorders (course of rifaximin (if SIBO is identifi ed) on the background of prolonged ingestion of psyllium) in patients with NAFLD of diff erent stages, is supported by the normalization of the content and profi le of SCFA in various biological substrates. In patients of group 3 there was noted the negative dynamics of estimated parameters SCFA. Thus, the results of the undertaken research of the parameters of SCFA in various biosubstrates indicate the marked changes in the intestinal microbiocenosis and their contribution to the development and enhancement of systemic metabolic processes. The inclusion of means aimed at correcting the microecological status disorders in the complex management of NAFLD is not only eff ective, but also pathogenetically necessary.

Keywords: food protein-induced enterocolitis syndrome, vitamin D, defi ciency, insuffi ciency
Abstract:Aim of the study. To study the status of 25 hydroxyvitamin D in case of food proteins induced enterocolitis syndrome in young children and to determine the relationship between its level and clinical and laboratory manifestations of the disease. Materials and methods. 72 children with Food Proteins Induced Enterocolitis Syndrome aged from 3 months to 3 years were examined. To confi rm the diagnosis, clinical-anamnestic, paraclinical (general blood analysis, coprology, feces for latent bleeding, total protein), and immunological (IgE total, IgE-specifi c antigen-specifi c method, lymphoquin-producing ability of T-lymphocytes to food allergens) were used. For studying the status of vitamin D in the serum of sick children 25 (OH) D3 was determined. Results. The average values of vitamin D in children with gastrointestinal food allergies had marked diff erences in comparison with the norm. Thus, in children with FPIES, they were 20.0 ± 4.4 ng / ml, at a rate of 45.1 ±8.04 ng / ml. Lower vitamin D values occurred in children with more severe clinical manifestations of the disease and, in part, with association with Ig E. By criteria, vitamin D defi ciency was found in 41.6% of children with FPIES, insuffi ciency in 18% of children, in 29 (40.2%) cases, the rates were within the normal range. Conclusion. Thus, it was founded a decrease in the vitamin D values by 2.25 times in food protein induced enterocolitis syndrome, compared with the norm, which dictates the need for the children with FPIES to make aqueous solutions of vitamin D.

Abstract:Growth pathology duodenal among patients of diff erent age groups determines the relevance of the study. Causes duodenal disease suffi ciently heterogeneous and include celiac disease, gluten allergy and various proteins, autoimmune disease, atopy, and also bacterial, parasitic and viral infection (Helicobacter pylori infection, giardiasis). One of the characteristics of the mucosal morphofunctional state is its neuroendocrine duodenal activity, which is provided enteroendocrine cells, and chromogranin synthesizing neuropeptides, in particular, chromogranin A (CgA), ghrelin and serotonin. The aim of our study was to determine whether these markers in the duodenal mucosa with similar morphological manifestations duodenitis of various etiologies in children. The material of the study were 40 biopsies of the distal duodenum, obtained by fi brogastroduodenoscopy in children aged 6 to 17 years old with morphologically verifi ed chronic gastroduodenitis (CGD). The fi rst group consisted of children with celiac disease, the second group — with Helicobacter pylori infection (H.p), the third group consisted of children with giardiasis, in the fourth (the control group) — children with reliably excluded above listed diseases and preserved architectonic mucosal duodenum without morphological characters gastroduodenitis.When immunohistochemical study (IHC) expression levels were determined Chromogranin A (Abcam 1: 400); Serotonin (Abcam 1:50); Ghrelin (Abcam 1: 100). The intensity of the reaction was assessed by two indicators — the relative expression area (Ot. Pl) and the optical density (OP). In our study, for the fi rst time we studied markers in enteroendocrine duodenitis of various etiologies. We were looking for a morphological tool that will help diff erentiate duodenitis with similar clinical and histological features. Increased expression of ghrelin, serotonin and chromogranin A, playing an important role in the mechanisms of disorders duodenum structure in celiac disease. When H.p infections a decrease in all studied markers, while giardiasis is not observed signifi cant changes. All of this allows us to diff erentiate duodenitis etiology and, therefore, reasonable to appoint therapeutic measures.

Abstract:The article presents a review of the literature on the etiopathogenesis, diagnosis and treatment of parasitic invasions in children. The etiological structure of parasites infecting the biliary system, their development cycles and places of the most frequent parasitism in the external environment are described. It is convincingly shown that Giardia has nothing to do with the gallbladder and the biliary tract. It is noted that the most frequent pathogens of parasitic invasions of the biliary tract in children are opisthorchiasis, clonorchosis and fascioliasis. The role of parasitic invasions in the formation of gallstones is shown. At the same time, the key pathogenetic mechanisms of stone formation in cholelithiasis on the background of parasitic invasion is the activation of cholesterol and pigment lithogenesis, the deconjugation of direct bilirubin in bile. It is shown that the main in the treatment of parasitic invasions is the use of etiotropic therapy (deworming). Based on a detailed analysis of modern literature, therapeutic tactics algorithms have been developed.

Keywords: gestational diabetes mellitus, insulin resistance, obesity
Abstract:Gestational diabetes mellitus (GDM) develops in 7–18% of women worldwide. The number of pregnant with GDM is steadily increasing. GDM is more likely to develop among obese patients. Women who are obese have features of chronic low-grade infl ammation, manifest by increased tumour necrosis factor alpha (TNF-α), interleukin-6 (IL-6), interleukin-12 (IL-12), and high sensitivity C-reactive protein (hsCRP). Obesity is characterised by insulin resistance, and down-regulation of adiponectin and up-regulation of leptin, resistin and retinol-binding protein-4 (RBP4) contribute to this. Obesity and excess gestational weight gain results in a three-fold increased risk of adverse pregnancy outcomes, including long term metabolic syndrome and endocrine diseases for baby. Off spring born from pregnancies complicated by GDM has higher body mass index (BMI) compared with non-GDM off spring and has high risk of obesity throughout all periods of childhood. GDM may have impact on genetic modifi cations in the off spring.
