It also discusses the potential clinical applications of UMOD as a predictive biomarker for early CKD detection, risk stratification, and targeted interventions. The development of transcriptomic, proteomic, and metabolomic approaches allows for a more comprehensive study of UMOD function and its interactions with other genetic and metabolic pathways. Chronic kidney disease (CKD) is a growing global health concern, affecting millions of people worldwide. Genetic factors play a crucial role in the etiology and progression of CKD, influencing susceptibility, disease severity, and treatment response. Among these factors, the UMOD gene, which encodes the glycoprotein uromodulin, is recognized as a key regulator of kidney function, tubular integrity, and disease susceptibility. UMOD polymorphisms affect kidney function by altering sodium transport, modulating immune responses, and regulating oxidative stress, thereby contributing to hypertension, nephron damage, and CKD progression.</p> <p>Recent GWAS (genome-wide association studies) have confirmed the association between UMOD polymorphisms and an increased risk of CKD and its related complications. Additionally, a significant correlation has been identified between UMOD and hyperuricemia, as uromodulin plays a crucial role in uric acid transport and excretion. <strong>Conclusion</strong>: Personalized medicine based on UMOD genotyping opens new opportunities for individualized risk assessment, tailored pharmacotherapy, and lifestyle modifications to slow CKD progression. Additionally, promising therapeutic strategies are being developed, including pharmacological modulation of UMOD expression and gene therapy.The integration of genetic knowledge with clinical applications highlights the significance of UMOD in CKD pathogenesis and positions it as a promising target for precision nephrology, potentially improving clinical outcomes and optimizing patient management strategies.</p>2025-02-25T00:00:00+05:00Copyright (c) 2025 https://fdoctors.uz/index.php/journal/article/view/96CONNECTIVE TISSUE DYSPLASIA AS AN ELEMENT IN THE DEVELOPMENT OF PATHOLOGY OF SOME BODY SYSTEMS (literature review)2025-02-26T02:16:04+05:00Nargiza Abdukadirovanagijon@mail.ru<p>The literature review examines connective tissue dysplasia and their role in the pathogenesis of diseases of the cardiovascular, respiratory, immune and other body systems. The etiological and morphological aspects of the development of this pathology, classification, as well as clinical features of the course of certain diseases against the background of connective tissue dysplasia in both adults and children are presented. In conclusion, it should be noted that the relationship between the external phenotypic signs of connective tissue dysplasia and the features of the morphology and function of internal organs has not been sufficiently studied. The issue of the frequency and clinical significance of individual minor developmental anomalies, as well as the combination of external manifestations of dysplastic syndrome with the nature and degree of involvement of the central and autonomic nervous systems and internal organs in systemic pathology of connective tissue remains unclear. The issue of the clinical form of manifestations of lesions on the part of internal organs remains controversial. Based on the above, it seems necessary to further study the role of connective tissue dysplasia in the formation and development of diseases of internal organs for the purpose of its early diagnosis, clinical assessment, prevention and treatment of diseases associated with it.</p>2025-02-25T00:00:00+05:00Copyright (c) 2025 https://fdoctors.uz/index.php/journal/article/view/90RESULTS OF THE STUDY OF COMPARATIVE ANALYSIS OF THE DEVELOPMENT OF COMPLICATIONS AFTER COVID-19 VACCINATION WITH DIFFERENT GROUPS (TYPES) OF VACCINES IN THE PRESENCE OF CONCOMITANT CHRONIC DISEASES IN MEN OF DIFFERENT AGES OF THE POPULATION OF THE FERGANA2025-02-26T02:17:39+05:00Shoyadbek Todzhikhazhaevshoyatbektojixojayev@gmail.comDilfuza MamarasulovaDilya2580559@gmail.com<p><strong>Relevance.</strong> The study of the post-COVID state among the vaccinated population of Uzbekistan is important to determine the risk factors characteristic of the local population, as well as to identify the characteristics of the course of the disease and effective preventive strategies in remote areas such as the Fergana Valley. <strong>Objective</strong>. The objective was to study the preventive strategy in the development of complications after vaccination with Covid-19 with various vaccines in healthy residents and residents with concomitant chronic diseases in different age groups. <strong>Materials and methods of research</strong>.

The tumor microenvironment (TME) plays a crucial role in cancer progression, immune evasion, and resistance to therapy. Immune cells, particularly CD4+ and CD8+ T cells, along with immune checkpoint proteins like PD-L1, significantly influence tumor behavior and therapeutic response. Understanding their roles in ovarian cancer may provide insights into novel immunotherapeutic strategies. <strong>Materials and methods</strong> <strong>of study.</strong> A total of 135 ovarian cancer patients from the Republican Specialized Scientific and Practical Medical Center of Oncology and Radiology, Samarkand Branch, were included in this study. Tumor samples were obtained through biopsy or surgical resection, and immune profiling was performed using multiplex immunohistochemistry and flow cytometry. The expression levels of CD4+, CD8+, and PD-L1 were quantified, and their spatial distribution within the TME was analyzed. Correlations between immune profiles and clinical outcomes, including survival rates and response to immunotherapy, were assessed. <strong>Research results. </strong>CD4+ T helper cells exhibited functional diversity, with Th1 cells promoting anti-tumor immunity, whereas Th2 and regulatory T cells (Tregs) contributed to immune suppression in advanced tumors. High CD8+ T-cell infiltration correlated with improved survival; however, elevated PD-L1 expression was associated with T-cell exhaustion (PD-1, TIM-3, LAG-3) and immune evasion. Increased PD-L1 levels were linked to poor prognosis, reinforcing its role as a key immune checkpoint regulator. <strong>Conclusion</strong>. This study highlights the prognostic significance of CD4+, CD8+, and PD-L1 expression in ovarian cancer. Immune profiling may aid in personalized treatment strategies, optimizing immunotherapy efficacy. Future research should focus on integrating multi-omics approaches to enhance patient stratification and improve therapeutic outcomes.</p>2025-02-25T00:00:00+05:00Copyright (c) 2025 https://fdoctors.uz/index.php/journal/article/view/98MICROALBUMINURIA AS AN INDICATOR OF METABOLIC DISORDERS IN OBESITY CHILDREN2025-02-26T02:15:45+05:00Nargiza Goyibovanargiza.goyibova@gmail.comLilya Garifulinams.garifulina77@mai1.ru<p>The original article presents the results of a study of the relationship between microalbuminuria and carbohydrate and lipid metabolism parameters in children with obesity. The results of the study are recommended for widespread implementation in the practical activities of general practitioners and pediatricians. <strong> </strong><strong>Research objective:</strong> To determine the relationship between microalbuminuria and carbohydrate and lipid metabolism parameters in children with obesity. <strong>Materials and methods:</strong> 55 children with primary exogenous constitutional obesity aged 7 to 18 years, as well as 20 children with normal body weight were studied. A set of anthropometric, clinical, and biochemical studies was conducted. <strong>Results of the study:</strong> a relationship was found between the degree of obesity and the severity of carbohydrate metabolism disorders and dyslipidemia in children, which was expressed in an increase in the level of cholesterol, triglycerides, LDL and a decrease in HDL, an increase in immunoreactive insulin and an increase in the IR HOMA R index. The study showed a relationship between the pathological level of urine albumin and the degree of pathology of carbohydrate and lipid metabolism, which indicates a significant contribution of the degree of metabolic disorders to the pathology of the functional capacity of the kidneys. <strong>Conclusion:</strong> in obesity, the kidneys are one of the first and main target organs most susceptible to damage, since they are the first to take on the function of correcting metabolism with an increase in the volume of adipose tissue. Thus, patients with excess accumulation of fat mass in the body should be considered as a group at very high risk of developing chronic kidney disease.</p>2025-02-25T00:00:00+05:00Copyright (c) 2025 https://fdoctors.uz/index.php/journal/article/view/99FEATURES OF VITAMIN D METABOLIC METHODS AND ITS CONTRIBUTION TO THE DEVELOPMENT OF METABOLIC SYNDROME IN CHILDREN2025-02-26T02:15:26+05:00Lilya Garifulinams.garifulina77@mail.ruMaksuda Ashurovaashurovamaqsuda31@gmail.com<p>The original article presents the results of a study of the metabolic state and cholecalciferol concentration in children and adolescents who are overweight and obese, determining the role of vitamin D in the formation of metabolic syndrome in children and adolescents. The results of the study are recommended for widespread implementation in the practice of general practitioners in central district primary health care clinics. <strong>The aim of the study</strong> was to determine the state of metabolism and concentration of cholecalciferol in overweight and obese children and adolescents, with the determination of the role of vitamin D in the formation of metabolic syndrome in children and adolescents. <strong>Materials and methods:</strong> 106 children and adolescents with exogenous constitutional type of obesity, as well as 30 children and adolescents with normal body weight were examined. A complex of anthropometric, clinical, biochemical, enzyme immunoassay studies was conducted to determine the level of carbohydrate and lipid metabolism, as well as vitamin D. <strong>Results of the study: </strong>it was revealed that the pathology of carbohydrate metabolism in overweight and obese children and adolescents occurs in 47.6% of cases, an imbalance of lipid metabolism – in 38.6%, insufficiency and deficiency of cholecalciferol in blood serum – in 76.9% of cases of severe obesity. The results allowed us to establish the presence of metabolic syndrome in 58.4% of children with signs of abdominal obesity, while its complete variant was observed in 20.9%.

The primary group comprised 12 patients (28.6%) with complicated cases involving bleeding, while the comparison group included 30 patients (71.4%) with an uncomplicated course. The study analyzed anamnesis, clinical characteristics, and pH levels in affected children. Several prognostic factors for complicated duodenal ulcers were identified, including gender, age, genetic predisposition, erosive gastroduodenitis, multiple ulcerations, high bacterial colonization, and low pH levels in the antroduodenal region. <strong>Results and discussion</strong>. Analysis of medical history showed that 75% of children in the primary group had a family history of duodenal ulcer, with 33.3% of relatives experiencing complicated forms of the disease. In the comparison group, hereditary factors were present in 46.7% of cases, though none of their relatives had complications. Helicobacter pylori infection was detected in all patients from the complicated ulcer group (100%), while 80% of the control group tested positive. Additionally, elevated IgG titers against HP were significantly more common in the complicated ulcer group. <strong>Conclusions</strong>. Key prognostic markers for complicated duodenal ulcers in children include male gender, older school-age status, hereditary factors, extensive ulcerated areas, and multiple ulcerations. Early diagnosis and proactive medical supervision can help minimize the risk of severe complications in these patients.</p>2025-02-25T00:00:00+05:00Copyright (c) 2025 https://fdoctors.uz/index.php/journal/article/view/103THE RELEVANCE OF RESPIRATORY DISEASES IN PEDIATRICS: RISK FACTORS FOR BRONCHO-OBSTRUCTIVE SYNDROME2025-02-26T02:14:27+05:00Shoira Ibatovash.ibatova@mail.ru<p><strong>Relevance. </strong>Respiratory diseases remain one of the most pressing problems in pediatrics, and in the Republic of Uzbekistan they occupy the first place in the structure of morbidity and mortality in children<strong>. </strong><strong>Purpose of the study.</strong> Assessment of risk factors contributing to the development of broncho-obstructive syndrome in children.<strong> Methods and materials. </strong>A retrospective analysis of the case histories of 912 children aged 1 to 3 years hospitalized with BOS in the pediatric intensive care unit of the Samarkand branch of the Republican Scientific Center for Emergency Medical Care in the period from 2022 to 2024 was carried out. <strong>Results and discussion.</strong> In the group of children with BOS associated with AOB, boys significantly predominated - 325 cases (65.8%) compared to 169 girls (34.2%).
