Chronic hepatitis B (CHB) remains one of the most urgent problems in modern medicine. There are about 296 million people with CHB worldwide, 820 thousand dying annually of liver cirrhosis and hepatocellular carcinoma. Objective. To study the immunodeficiency syndrome peculiarities in acute hepatitis B (AHB) convalescents. Material and methods. We have studied immunodeficiency syndrome (IDS) in 104 AHB convalescents, the control group comprised 78 apparently healthy donors. All examined were between the ages 18-45. IDSs were studied according to the IDS Map developed by Acad. R.V. Petrov (1987). Results. In 17.3% of AHB convalescent patients IDSs were absent, while in 82.7% - at least one of the three IDSs (infectious, atopic and autoimmune) was detected. In 44.2% of cases, clinical variants of one IDS were noted, in 34.9% - those of two syndromes, in 20.9% - those of three syndromes simultaneously in various combinations. Convalescence from AHB with IDS either had a non-smooth course or the disease transformed into a chronic process in 24.4%, while in the control group - in 12.3% of cases. Conclusions. AHB with IDS should be included in the progredient form, i.e. as a high-risk pathology of liver cirrhosis and hepatocarcinoma development, thus determining its appropriate therapeutic strategy.","PeriodicalId":34878,"journal":{"name":"Gepatologiia i gastroenterologiia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47755356","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}

When treating the dehiscence of the esophagus and its anastomoses, it is necessary to fulfil the following tasks: drainage and sanitation of the mediastinum and pleural cavity, replenishment of protein losses and energy costs, dehiscence closure and treatment of present purulent complications. Objective. To improve the treatment outcomes of esophageal and its anastomoses dehiscence using modern minimally invasive video-assisted thoracoscopic techniques. Material and methods. 20 patients (15 (75%) men and 5 women (25%)) with esophageal and its anastomoses dehiscence underwent treatment. The mean age of patients was M±SD = 55 ± 10 (CI (95%) = 50-60; min−35; max−76). Body mass index averaged M±SD = 20.98 kg/m2 (CI (95%) = 18.61-22.45; min−15,82; max−38,27). Results. The reasons for the surgical interventions resulting in dehiscence were as follows: esophageal cancer - 6 (30.0%); esophageal diverticula - 4 (20.0%); cardia achalasia − 2 (10.0%); esophageal chemical burn − 4 (20.0%); benign formations - 4 (20.0%). The development of clinical manifestations of dehiscence occurred at M±SD = 170 ± 61 hours, (CI (95%) = 141 - 198). Conclusions. The dehiscence management of the esophagus, esophagogastroanastomosis or esophagoenteroanastomosis either by installation of a T-shaped drainage system or fixation of transpleural tube to the thoracic wall at a place of dehiscence enables to preserve the esophagus or a created conduit, to reduce surgical stress as well as the duration of intervention and is regarded as an adequate surgical option.","PeriodicalId":34878,"journal":{"name":"Gepatologiia i gastroenterologiia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42212753","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}

Intrahepatic cholestasis of pregnancy (COP) is the most common complication of pregnancy that occurs during the 2nd-3rd trimester and is accompanied by liver damage manifested as cholestasis and cytolysis. Objective. To establish the role of cytokine response in the pathogenesis of COP as well as its obstetric and perinatal complications. Material and methods. 87 pregnant women were examined: 57 with intrahepatic cholestasis of pregnancy and 30 patients of the comparison group. The levels of pro-inflammatory (interleukin 6) and anti-inflammatory (interleukin 4) cytokines were determined by enzyme-linked immunosorbent assay, and their prognostic significance as predictors of obstetric and perinatal complications in women with COP was estimated. Results. The course of COP is accompanied by a decrease in the concentrations of IL-6 and IL-4 cytokines and a lower ratio of IL-4/IL-6 (P(U)IL-6=0.041; P(U)IL-4=0.0007 and P(U)IL4/IL-6=0.008). The concentration of IL-6 in blood serum that is > 2.53 pg/ml (Se=83.3 %, Sp=73.9 %; AUC=0.822; 95 % CI 0.636–0.938; p=0.004) and IL-4 concentration that is > 41.99 pg/ml in symptomatic COP (Se=100.0 %, Sp=78.6 %; AUC=0.839; 95 % CI 0.593–0.965; p=0.011) are regarded as a risk factor for preterm labor (PL) in women with COP. The concentration of IL-6 > 3.07 pg/ml in women with COP and negative vaginal discharge culture can be considered as a predictor of meconium staining of amniotic fluid (MSAF) (Se=100.0 %, Sp=62.9 %; AUC=0.770; 95 % CI 0.597–0.895; p=0.024). Conclusions. COP is accompanied by a lower level of IL-6; an atypical immune deviation with no shift towards the Th2 immune response that is characteristic of a normal pregnancy; as well as an imbalance in the cytokine response with a decrease in the anti-inflammatory link. Preterm birth in patients with COP is associated with higher levels of IL-6 during pregnancy. The release of meconium into amniotic fluid in women with COP (in the absence of significant pathogenic and opportunistic microflora according to the results of vaginal discharge culture) correlates with higher concentrations of IL-6 in the blood.","PeriodicalId":34878,"journal":{"name":"Gepatologiia i gastroenterologiia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43908997","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}

Three metabolic pathways that can function simultaneously are known to be involved in ethanol oxidation in the liver: alcohol dehydrogenase pathway, microsomal ethanol-oxidizing system, and catalase pathway. Though the cytochrome P450-dependent microsomal ethanol-oxidizing system plays an insignificant role in metabolism of small amounts of ethanol, it is induced in case of ethanol excess and becomes essential when ethanol is abused. The main components of this system are cytochrome P450 (CYP) isoforms of smooth endoplasmic reticulum. Objective. To characterize the role of the key isoforms of cytochrome P450 in ethanol oxidation. Material and methods. We carried out an analysis of modern literature data on the role of the main isoforms of cytochrome P450 in liver metabolism of ethanol. Results. Data on the primary role of cytochrome CYP2E1 in ethanol metabolism, as well as on the contribution of isoforms CYP1A2, CYP2B1/2, CYP2C, CYP3A4, CYP4B1 to ethanol oxidation are presented. Conclusions. Ethanol is metabolized by many CYPs of endoplasmic reticulum of hepatocytes.

The probability of undergoing surgery always predetermines the state of stress in a person; therefore, it is advisable to search for ways to optimize and (or) reduce this unfavourable effect. Objective. To find out the mechanism of vitamin B1 antistress activity during surgery. Material and methods. Metabolism intensity was investigated on donors’ blood lysates (n = 19) and those of patients with stage III stomach cancer (n = 64), referred to an elective surgery, aged 51-70. The blood was taken from the cubital vein three days before the operation, after premedication, during the most traumatic moment of the operation, after extubation, as well as on the first and third days of the postoperative period. The surgery was performed under combined multicomponent anesthesia using nitric oxide, sodium hydroxybutyrate, and epidural block. Thiamine and thiamine diphosphate kinase activities were assessed by the concentration of the formed thiamine di- and triphosphates of the vitamin. The activities of thiamine mono-, di- and triphosphatases were determined by the release of inorganic phosphate. The concentration of inorganic phosphate was recorded colorimetrically. The content of B1 and its derivatives in the blood was determined by the method of ion-pair reversed-phase HPLC. Results. There has been observed an increased content of thiamine monophosphate and that of free thiamine in the blood of donors and patients with stomach cancer. The registered rate of the hydrolytic thiamine monophosphatase reaction is not high. At the stages of premedication and maximum trauma of surgical exposure, the concentration of monophosphoric ester rapidly decreases alongside with monophosphatase activation. Therefore, the thiamine monophosphate hydrolysis is the rate-limiting link of vitamin B1 metabolism. The level of free thiamine remains persistently increased at all stages of surgical treatment. Thiamine monophosphatase activity is manifested at two pH optima – of 6.0 and 9.0. Thiamine monophosphate hydrolysis at pH of 9.0 is catalyzed by alkaline phosphatase. At pH of 6.0, in addition to thiamine monophosphoric ester, the enzyme hydrolyzes only p-nitrophenyl phosphate, flavin mononucleotide and phosphotyrosine, that allows it to be classified as hepatic acid phosphatase. The noted changes in B1 metabolism under stress concern mainly non-coenzyme forms - thiamine mono-, triphosphate, and free thiamine, which are used at the stages of thiol reduction as important components of insulin synthesis. Conclusions. The use of vitamin B1 allows to optimize the development of the stress response at all stages of surgical treatment. Its protective effect is achieved through the activation of the insulin-synthetic function of the pancreas, which increases the level of immunoreactive insulin in the blood. The formation of the most favorable physiological conditions for insulin synthesis provides an increased background of free thiamine, which is created due to the hy","PeriodicalId":34878,"journal":{"name":"Gepatologiia i gastroenterologiia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49550596","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}
