The purpose of the study is to determine the significance of genetic factors in the development of chronic nephritic syndrome in children and to clarify the features of the clinical course
The оbject of research were 129 children aged 4-15 years who were treated for chronic nephritis in the nephrology department of the Samarkand Regional Multidisciplinary Paediatric Medical Centre.
The scientific novelty of the study is as follows:it has been established that the severity of chronic nephritic syndrome in children is associated with clinical manifestations (gradual development, dyspepsia, abdominal pain) and an increase in the amount of Cystatin C in the blood;for the first time, it was revealed that the development of sclerotic lesions due to increased proliferation in patients with the presence of the MMP-9 (A-8202G) rs 11697325 genotypes in chronic nephritic syndrome leads to a worsening of the clinical course of the disease; established early diagnostic marker MMP-9 (A-8202G) rs 11697325 and its tissue inhibitor TIMP-2 (C536T) rs 11551797 in chronic nephritic syndrome in children in the diagnosis of the disease; for the first time, the prognostic value of the alleles of the MMP-9 (A-8202G) rs 11697325 genes and the homozygous G/G genotype in determining the risk of developing the disease in children with chronic nephritic syndrome has been proven.
Implementation of the research results. Based on scientific results of evaluation of the role of polymorphic genes of matrix metalloproteinase and its tissue inhibitors in chronic nephritic syndrome in children: methodological recommendation “The role of polymorphic genes of matrix metalloproteinase and its genetic inhibitors in the development of chronic nephritic syndrome in children” was developed and approved (reference of the Ministry of Health of the Republic of Uzbekistan No. 8n-r / 554 of 30.02.2022).
This methodological recommendation made it possible to predict the development of chronic nephritic syndrome in children and improve preventive measures; approved and developed on the basis of scientific results of research on early diagnosis and prognosis of chronic nephritic syndrome “Dynamics of clinical and laboratory parameters in nephritic syndrome in children”, (reference of the Ministry of Health of the Republic of Uzbekistan No. 8n-r / 555 of 30.02.2022).
This methodological recommendation made it possible to optimize the diagnosis and treatment tactics for various forms of nephritic syndrome in children;
The results obtained were implemented in the practice of health care, in particular, in the Republican Children's National Medical Center, in the 1st clinic of the Samarkand State Medical University, in the Samarkand Regional Children's Multidisciplinary Medical Center (conclusion No. 8 n-r/324 of 21.06.2022 of the Ministry of Health of Uzbekistan).
The application of the obtained results to practice has made it possible to reduce the frequency of recurrence of the disease in children, prevent complications of the disease, improve the quality of life of patients, diagnose and prevent the disease.
The structure and scope of the dissertation. The dissertation consists of an introduction, 4 chapters, conclusions, practical recommendations. The volume of the dissertation is 120 pages.
In order to identify risk factors for the development of irritable bowel syndrome in children depending on the clinical variants of the disease, age, gender, были обследованы the basic group consisted of 56 children suffering from irritable bowel syndrome aged 7-14 years (middle age of 10.0±0,69 years), including 30 girls and 26 boys. The comparison group consisted of 100 patients with diseases of the upper gastrointestinal tract without IBS (the Syndrome of Irritated Bowel). According to the findings of a survey of 56 children aged 7-14 years, it was found that the stream of irritable bowel syndrome in children depends on age, sex and clinical options. The disease is frequently occurres in younger boys (57,4%) and girls (68,1%) of high school age. Pronounced clinical manifestations of the disease marked in children in the senior school age (57,8%) and in patients with clinical variant of irritable bowel syndrome with predominant diarrhea (30,6%).
The purpose of the study. Study of the clinical presentation of irritable bowel syndrome in children depending on the clinical variant of the disease, age, gender.
Materials and methods. 156 children and adolescents who passed the generally accepted set of studies for patients with gastropathology were examined.
Results. According to the data obtained from the study of 56 children aged 7-14 years, it was found that the course of irritable bowel syndrome in children depends on age, gender and clinical variant. The disease is more common in young boys (57.4%) and girls of high school age (68.1%). Clear clinical manifestations of the disease are observed in children of senior school age (57.8%) and in patients with a clinical variant of irritable bowel syndrome with a high prevalence of diarrhea (30.6%).
Синдром раздраженного кишечника (СРК) остается одним из распространенных кишечных заболеваний при котором несмотря на отсутствие болезненных изменений во внутренних органах, дети испытывают приступы сильных болей в животе, сопровождающихся метеоризмом, диареей или запорами. Данное состояние характеризуется как высокой частотой встречаемости, так и развитием осложнений при длительном течение заболевания (особенно у детей 2-7 лет), риском формирования хронической гастроэнтерологической патологии. Данный синдром является полиэтиологичным и причины его возникновения в настоящее время до конца не исследованы.
Причина развития синдрома раздраженного кишечника (СРК) остается неясной. Разнообразные изменения физиологии кишечника оказывают влияние на симптоматику СРК. Развитие запора может объясняться замедлением, а развитие диареи - ускорением толстокишечного транзита.
Метаболический синдром является чрезвычайно актуальной проблемой современной медицины. Эксперты ВОЗ определяют метаболический синдром как новую пандемию века, охватывающую экономически развитые страны. Метаболический синдром широко распространен в популяции (около 20%).
To develop a method of modified set bronchophonography and set a diagnostic criteria of bronchial obstruction syndrome in young children. The study involved 60 patients with acute bronchiolitis and 60 healthy infants. We have developed the method of modified bronchophonography consisting of the registra-tion system of the respiratory noises and the personal computer. The analysis of respiratory noise was conduct-ed using the special software. Method of modified bronchophonography is important in the diagnosis of bron-chial obstruction syndrome in infants because of its objectivity, simplicity and accessibility of use in pediatric practice. New informative diagnostic criteria of bronchial obstruction syndrome in children has been estab-lished - E:I index, bronchial obstruction is diagnosed at E:I index≥1,20, bronchial obstruction is absent if E:I index≤1,19
