Combination therapy may include various medications, most often biological and immunosuppressants. Despite the fact that biological therapy of IBD has traditionally focused on drugs that block tumor necrosis factor-alpha, the development of new drugs that act on different targets, such as vedolizumab, ustekinumab, tofacitinib or ozanimod, has made it possible to use combined immunosuppressive therapy. The treatment algorithm suggests various combinations of dual biological therapy for 2 categories of patients with IBD: patients with well-controlled luminal IBD and uncontrolled extra-intestinal symptoms (indications such as arthritis or psoriasis) and patients with refractory, uncontrolled IBD. Thus, data on the efficacy and safety of dual biological therapy as a method of treating Crohn’s disease (CD) or ulcerative colitis (UC) remain very limited. In fact, the vast majority of literature consists of individual cases and a series of cases. Given the lack of studies with a high level of evidence, gastroenterologists have turned to larger studies of dual biological therapy in other areas of medicine, such as rheumatology and dermatology. The aim of this article is to demonstrate clinical experience of combination therapy with genetically engineered biological drugs and selective immunosuppressors in UC, to analyze potential adverse effects or risks associated with combination therapy, and to determine future directions in the use of this treatment.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"147 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140504941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of the relationship between molecular genetic data, physical characteristics and metabolic individuality (regulation of biogenesis, energy balance, lipid metabolism, glucose homeostasis, etc.) is a promising vector of research, both in the population as a whole and in various nosologies, primarily for hereditary and metabolic diseases characterized by impaired physical development and metabolic balance, including cystic fibrosis (CF), obesity, diabetes mellitus. The first studies were devoted to the study of these parameters in athletes. The genotype-phenotype study in CF has been actively studied for the past few years. It has been shown that environmental factors can determine clinical polymorphism in CF, which account for nearly 50% of lung function variability in this disease. However, CF patients with similar molecular genetic variants of the CFTR gene and in a single habitat (for example, in siblings) can have highly variable clinical manifestations. Genes whose products provide cell energy exchange (PPARA, PPARG, PPARD, PGC-1, UCP2, UCP3, ACTN, ACE) can also be “modifiers” and have an effect on the phenotype, the difference in clinical manifestations of the disease of patients with CF, the relationship of which in this category of patients has not been studied. The world has seen a steady increase in obesity and its complications. Patients with CF from the category of persons with nutritional deficiency in recent decades began to move into the category of overweight patients, which requires study. This review summarizes the recent achievements of studying genes whose products provide energy exchange of the cell, discusses the development of the relationship both with the physical characteristics of individuals and with pathological changes in the body as a result of the appearance of metabolic products in excess or with altered physicochemical properties and functional activity parameters leading to various diseases.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"14 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140505553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The underlying mechanisms include DNA methylation and covalent modification of histones by methylation, acetylation, phosphorylation, or ubiquitination. The complex interplay of various epigenetic mechanisms is mediated by enzymes operating in the cell nucleus. Modifications in DNA methylation are carried out primarily by DNA methyltransferases (DNMTs) and ten-eleven translocation proteins (TETs), while a variety of enzymes such as histone acetyltransferases (HATs), histone deacetylases (HDACs), histone methyltransferases (HMTs), and histone demethylases (HDMs)) regulate histone covalent modifications. In many pathological conditions such as cancer, autoimmune, microbial inflammatory, metabolic, allergic diseases and/or low vitamin D availability, the epigenetic regulatory system is often disrupted. Vitamin D interacts with the epigenome at several levels. First, critical genes in the vitamin D signaling system that encode for the vitamin D receptor (VDR) and the enzymes 25-hydroxylase (CYP2R1), 1α-hydroxylase (CYP27B1), and 24-hydroxylase (CYP24A1) have large CpG islands in their promoters. areas and therefore can be suppressed by DNA methylation. Second, the VDR protein physically interacts with coactivator and corepressor proteins, which in turn are in contact with chromatin modifiers such as HATs, HDACs, HMTS, and chromatin remodelers. Third, a number of genes encoding chromatin modifiers and remodelers, such as HDM from the Jumonji C (JmjC) domain containing proteins and lysine-specific demethylase (LSD) families, are primary targets for VDR and its ligands. Finally, there is evidence that certain VDR ligands have DNA demethylating effects. In this review, the authors discuss the regulation of the vitamin D system by epigenetic modifications and how vitamin D contributes to the maintenance of the epigenome and assess its impact on health and disease.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"195 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140504885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess changes in the structure of the small intestine microbial community in the context of the “gut microbiota-immune system-brain axis” in healthy aging, depression and dementia. Materials and methods. 74 elderly people included in the groups: “Healthy ageing”, “Depression”, “Dementia” were investigated. Evaluation of 5 main types of microorganisms of the small intestine (Bacteroidetes, Firmicutes, Actinobacteria, Proteobacteria, Fusobacteria) by method of gas chromatography - mass spectrometry of microbial markers was carried out. For statistics, hierarchical cluster analysis with the construction of a heat map was used. Results. Reconstruction affected 15 out of 30 studied bacterial species of the phylums Firmicutes, Actinobacteria, Proteobacteria in the “Dementia” and “Depression” groups in relation to the “Healthy ageing” group. In depression, the number of all types of bacteria involved in the fermentation of food polysaccharides increased in relation to the “Healthy ageing” group. In dementia, low levels of Clostridium spp., Eubacterium spp., Bifidobacterium spp. was shown, in relation to depression, but number of C. perfringens, С. difficile and facultative anaerobes: Streptococcus spp., Enterococcus spp., Lactobacillus spp., S. aureus, S. epidermidis was increased, compared to “Healthy ageing” group.

This systematic review of randomized placebo controlled clinical trials reviews current data on the evaluation of the efficacy of melatonin in patients with IBS. Material and research methods. The search and selection of publications was carried out in the PubMed, ScienceDirect, ClinicalTrials.gov, Cochrane Library, eLibrary, medRxiv and International Clinical Trials Registry Platform databases from their publication until October 30, 2022. Results. The inclusion criteria were met by four randomized placebo-controlled trials, totaling 155 participants, and these trials were included in the subsequent analysis. All investigations revealed a considerable reduction in the frequency and severity of bloating, as well as a tendency for other intestinal symptoms to regress. Two trials reported an improvement in patients’ quality of life, albeit one of the studies did not find these changes to be statistically significant, and the other did not assess them. This review demonstrates that melatonin is effective in treating IBS by lowering the frequency and severity of the condition’s symptoms in the vast majority of published RCTs. The poor number and sample size of clinical trials, along with their inadequate methodological quality, prevent us from drawing any firm conclusions about the contribution of melatonin to the improvement of IBS patients’ quality of life. To confirm melatonin’s significance in the treatment of IBS patients, larger studies are required to assess its efficacy and safety when used in various doses.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"150 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140505049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ulcerative colitis (UC) and Crohn’s disease (CD) belong to the category of inflammatory bowel disease (IBD) and are one of the most pressing problems of gastroenterology worldwide, including due to the development of specific life-threatening complications. Chronic inflammation in the colon in IBD is the cause of the development of one of these complications - colorectal cancer, which requires disabling colectomies and is also one of the leading causes of death among IBD patients. In the Russian population of IBD patients the prevalence of dysplasia and cancer of the colon mucosa has not been previously studied in large epidemiological studies. The aim of the study was to assess the incidence of colorectal cancer in patients with IBD in St. Petersburg. Materials and methods. Within the framework of this publication, the results of three studies were compared: a single-center retrospective cohort study conducted on the basis of the city center of IBD in St. Petersburg (516 patients with IBD who admitted to this medical institution for the period 2020-2023); a multicenter epidemiological study aimed at assessing the clinical features of IBD among the population of St. Petersburg (1072 patients with IBD who admitted to 42 outpatient clinics and 6 city hospitals in 2018-2020); registry study based on the general statistical module of the regional IBD Register of St. Petersburg, operating on the basis of a regional fragment of the unified healthcare state information system (12,858 patients with IBD, data collection period: 2019-2022). Results. As a result of comparing data from three studies, the incidence of IBD-associated colorectal cancer in St. Petersburg was calculated, which was 15.7 cases per 10,000 patients with UC per year and 11.5 cases per 10,000 patients with CD per year. Compared to the population of St. Petersburg as a whole, the likelihood of developing colorectal cancer in patients with UC was 2.9 times higher, in patients with CD - 2.4 times higher. At the same time, in a single-center study, when assessing the prevalence of IBD-associated colorectal cancer, it was found that compared with other life-threatening complications of IBD, it was much less common: toxic dilatation of the intestine occurred 3 times more often, intestinal perforation occurred 20 times more often, decompensated bowel stricture occurred 21 times more often, and severe anemia requiring blood transfusion occurred 36 times more common. Also, as a result of a single-center study, it was found that for 1 case of IBD-associated dysplasia of the colon mucosa, there were 5 cases of sporadic dysplasia. Conclusion.

Purpose: to explain the relationship between the level of total bilirubin and the activity of the inflammatory process in Crohn’s disease, which allows the introduction of the studied integrative indicator in clinical practice. Materials and methods. Based on the results of scientific studies of biomarkers of oxidative stress (albumin-modifying ischemia - plasma IMA, malondialdehyde - plasma MDA) and the antioxidant system (plasma SH-groups, catalase and reduced erythrocyte glutathione), as well as a simultaneous study of the level of total bilirubin in children diagnosed with Crohn’s disease. To search for a differential method for assessing the level of Crohn’s disease activity by the degree of bilirubin, use binary logistic regression. Results and survey. The results of the study showed a clear relationship between the increase in bilirubin levels and the severity of oxidative stress. It has been established that with a decrease in the level of total bilirubin, there is a predominance of oxidative stress over the antioxidant system, which leads to an increase in inflammation activity. It has been proven that the level of total bilirubin can be used in the complex activity of diseases as a minimally invasive, as well as an objective and acute marker. The sensitivity and specific sensitivity of this protocol is 90.9% and 93.3% respectively, which allows the use of total bilirubin as a marker of inflammation in Crohn’s disease.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"23 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140505327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gut microbiome is involved in systemic inflammation and immune activation, which contributes to the persistence of HIV infection. Although the exact pathogenesis of HIV infection and changes in the intestinal microbiome in the form of a decrease in bacterial diversity is still unclear, normalization of the intestinal microbiome in HIV infection can reduce inflammation, and thereby lead to a decrease in the possible reservoir for HIV infection. The authors of the article presented modern hypotheses about the interaction of the intestinal microbiome with systemic inflammation, as well as the relationship between the intestinal microbiome and the persistence of HIV infection. The inability of modern treatment methods to affect the hidden reservoir and deplete it is the main obstacle to the cure of HIV infection.
