Various classes of genetically engineered biological therapy are available for the treatment of inflammatory bowel diseases (IBD). Vedolizumab, having a selective nature of action, has a higher safety profile of the drug, which suggests lower immunogenicity and, as a consequence, long-term efficacy. Materials and methods: A retrospective study was conducted on the basis of the National Medical Research Centre of Coloproctology named after A. N. Ryzhikh, which included 54 patients treated with vedolizumab. In the course of the work, the survival of therapy was evaluated, as well as the influence of demographic characteristics, localization, phenotype of the disease and other factors on the effectiveness of therapy. Results: The study showed 86.0% (95% CI 72.8-93.1) survival of therapy for 15 months and 75.9% (95% CI 58.8-86.7) for two years. No statistically significant differences were obtained when assessing the effect of gender, comorbidity, lesion localization, disease phenotype, smoker status and the use of glucocorticosteroids during vedolizumab induction. During the analysis, it was revealed that significant factors affecting the effectiveness of therapy are the age of CD debut less than 21 years and the SES-CD index index more than 7, as well as previous therapy with the use of two or more anti-TNF drugs. Discussion: Despite the small sample size, the findings allow us to predict the effectiveness of therapy, which may affect survival.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"178 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140504667","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 establish the prevalence of atherosclerotic lesions in the unpaired visceral artery branches of the abdominal aorta. To explore the features of clinical presentation, the state of the mucosa of the upper GI tract. Materials and methods. A total of 118 patients with atherosclerosis of the unpaired visceral artery branches of the abdominal aorta aged 45 to 89 years were examined. The comparison group included 120 patients without atherosclerosis in the unpaired visceral artery branches of the abdominal aorta. Patients in both groups had coronary atherosclerosis. Ultrasound dopplerography (USDG) as a screening technique, CT angiography, and MSCT aortography were used to verify occlusion-stenotic lesions in the unpaired visceral artery branches of the abdominal aorta. The diagnosis of erosion changes in the gastric mucosa was confirmed by clinical symptoms and endoscopic examination findings. Results. In our study, hemodynamically relevant stenosis (>70%) was identified in 28.8% of patients. The clinical presentation of atherothrombosis in mesenteric vessels was shown to be nonspecific. Abdominal pain was the most common symptom in the examined patients with abdominal angina (76.3%). The upper GI endoscopy in patients with a verified diagnosis of chronic abdominal ishemia (CAI) showed gastric mucosa atrophy (focal or diffuse) in 100% of cases. Gastric erosions are identified in 55.1% of patients. Gastric ulcers are observed in 27.1% of patients. Erosive and ulcerative lesions of the gastric mucosa are combined with atrophic changes in the mucosa. Erosive esophagitis was detected in 28.8% of patients. The frequency of detected focal abnormalities in the esophageal mucosa accounts for 27.3%, and those in the gastric mucosa is 54.2%, mainly due to intestinal metaplasia. Conclusion. Due to the increasing prevalence of obliterative vascular diseases, early detection of changes in the upper gastrointestinal tract remains an urgent challenge. The comprehensive endoscopic examination using additional endoscopic NBI and ZOOM techniques allows to identify all changes in the mucosa, including small focal abnormalities. Timely detection of the disease makes it possible to choose the right treatment method.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"131 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140505143","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 find out the effectiveness of the use of angiotensin-converting enzyme (ACE) inhibitors in the complex therapy of erosive and ulcer lesions of the stomach and duodenum in unstable angina pectoris (UA). Materials and methods. A survey of 109 patients with UA with gastroduodenal erosions and ulcers was carried out, taking into account their clinical signs, endoscopic features and the parameters of gastric secretion. The patients were divided into two groups depending on the nature of the treatment of erosions and ulcers. The first group included 40 patients treated with standard therapy, and the second one included 69 patients who additionally received ACE inhibitor lisinopril at an average dose of 7.27±0.16 mg a day. Results. The therapy by lisinopril resulted in decreasing of pain and dyspeptic syndrome, especially in patients with acute erosions, compared with conventional treatment group. According to endoscopic examination, in patients treated with lisinopril, an acceleration of repair processes in the tissues of the gastroduodenal zone was observed. The depth and size of damages, a reduction in the period of persistence of microbleeding signs and inflammatory changes in the periulcerous zone were also less pronounced in lisinopril patient’s group. In patients with acute erosions a decrease in the number and size of erosive defects of the mucous membrane was observed. The study of the parameters of gastric secretion showed that gastroduodenal erosions and ulcers in UA revealed the activation of the acid-peptic factor and a decreasing in the production of gastromucoproteins. Increased production of pepsinogen and a sharply reduced formation of protective mucus was observed in patients after conventional treatment, despite some positive dynamics. Normalization in pepsinogen secretion with some inhibition of the production of mucopolysaccharides was observed in Lisinopril treated patients at the end of therapy. Acid production in both groups was reduced, which was associated with could be provoked by an uptake of antisecretory agents. Conclusion. The use of ACE inhibitor lisinopril in the complex therapy in patients with UA with gastroduodenal erosions and ulcers is pathogenetically justified and clinically effective. This combination helps to reduce the duration of clinical signs, accelerate the healing of defects and normalize the parameters of gastric secretion.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"128 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140504963","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 study the frequency of genotypes and alleles of C282Y and H63D mutations in the HFE gene in patients with porphyria cutanea tarde of the West Siberian region and their influence on the clinical and biochemical characteristics of the disease. Materials and methods. We observed 14 patients with porphyria cutanea tarde (PCT), who underwent a comprehensive general clinical and instrumental examination. The indicators of the excretory profile of porphyrin metabolism indicators were purposefully determined, a molecular genetic examination was carried out to determine the genotypes and alleles of the C282Y and H63D mutations of the hemochromatosis gene HFE. Results and discussion. Molecular genetic research found that the HFE gene mutation was found in 7 patients (50.0%). Polymorphism for the C282Y allele was found in 2 (14.3%) patients, and for the H63D allele - in 5 patients (35.7%). Risk factors for the manifestation of PCT included frequent alcohol consumption and chronic HCV infection. Genotype 1b was recorded more often (9 people), less often - genotype 3a (4 people). The excretory profile of porphyrin metabolism indices in patients of both groups exceeded the control values. Porphyrin metabolism parameters in patients without HFE gene mutations were significantly higher than those in patients without HFE gene mutations. Conclusions. Polymorphism of the hemochromatosis gene HFE in PCT was detected in 50% of patients. The most common mutation was the H63D allele. The level of porphyrin metabolism disorders in patients with HFE hemochromatosis gene mutations is significantly lower. The clinical picture of PCT in all observed patients did not differ. Chronic viral hepatitis C is assessed as a risk factor for the manifestation of PCT.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82213789","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}

Materials and methods. The animals were divided into 5 groups of 6 animals each: control, acrylamide, acrylamide + complex compound of oxymethyluracil with ascorbic acid (MG-1), acrylamide + complex compound of oxymethyluracil with sodium succinate (MG-2), acrylamide + complex compound of oxymethyluracil with acetylcysteine (MG-10). The drugs were administered 1 hour before exposure to the toxicant for 28 days. After the end of the experiment, the animals were decapitated, the liver was removed, which was frozen in liquid nitrogen. Real-time reverse transcription polymerase chain reaction was used to analyze gene expression. Results. Exposure to acrylamide did not significantly affect the expression of the GSTP1, GSTT1, and GSTM1 genes in the liver of rats, however, for all the studied genes, there was a tendency to increase the value of the studied indicator. Prophylactic administration of a complex compound of oxymethyluracil with sodium succinate (MG-2) led to a statistically significant decrease in the transcriptional activity of the GSTM1 gene under conditions of toxic damage to the liver by acrylamide. Conclusion. The results of the study indicate the ability of the MG-2 drug to suppress the expression of the GSTM1 gene in the liver of rats when exposed to acrylamide. Further research is needed to better understand the molecular mechanisms of acrylamide-induced toxicity and to develop new therapeutic approaches to treat liver pathology.","PeriodicalId":12262,"journal":{"name":"Experimental and Clinical Gastroenterology","volume":"52 Pt 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83915001","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}
