We carried out a retrospective comparative study of cirrhotic patients with severe ascites and esophageal varices without bleeding before enrollment in the LTWL. Primary prophylaxis of variceal bleeding included the use of NSBBs (n = 97, group 1). These drugs were not used in the other patients (n = 91, group 2).Results. There were no significant differences between the groups in terms of clinical, laboratory and demographic parameters, MELD scores and Child-Turcotte-Pugh (CTP) classes for cirrhosis. Patient groups included in the study had no significant differences with respect to incidence of medium- and large-sized varices and incidence of severe ascites. Bleeding incidence was significantly lower in the NSBBs group than in the non-NSBBs group (52.6% and 95.6%, respectively, p = 0.0001).Conclusion. NSBBs constitute an efficacious therapy in primary prophylaxis of esophageal variceal bleeding, thereby saving life and preventing delisting of patients with ascites from the LTWL.","PeriodicalId":21400,"journal":{"name":"Russian Journal of Transplantology and Artificial Organs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89802942","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 pulsatile flow-generating device, hereinafter referred to as «pulsator», consists of a variable hydraulic resistance made in the form of a hull. A tube of elastic biocompatible material featuring an inner diameter of 11 mm is installed inside it. In the systolic phase of the left ventricle, due to systolic pressure, the elastic tube is fully opened, minimizing resistance to blood ejection. In the diastolic phase, due to suction action of the flow pump operating in constant revolutions, the elastic tube partially closes, creating additional hydraulic resistance to blood flow, which leads to reduced diastolic aortic pressure. Comparative assessment of axial-flow pump operation in pulsating and non-pulsating modes was carried out on a hydrodynamic stand that simulated the cardiovascular system. The following indices were calculated: arterial pressure pulsation (Ip), in-pump flow pulsation (AQ), energy equivalent pressure (EEP) and surplus hemodynamic energy (SHE).Results. When comparing axial-flow pump operation in pulsatile and continuous mode, arterial pressure pulsation index, in-pump pulsation index, and SHE index increased by 2.13 ± 0.2, 3.2 ± 0.2, and 2.7 ± 0.15 times, respectively, while EER index remained unchanged.","PeriodicalId":21400,"journal":{"name":"Russian Journal of Transplantology and Artificial Organs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79191033","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 first (I) control group «Standard Protocol» included 228 patients operated on at Botkin City Clinical Hospital from June 2018 to November 2021; tacrolimus was administered postoperatively in a starting standard dosage of 0.2 mg/kg. The second group (II) consisted of 75 patients operated from December 2021 to November 2022, whose postoperative treatment involved a personalized extended-release tacrolimus dosing protocol. Induction immunosuppression was similar in both groups. The target tacrolimus level in the early postoperative period was considered to be 10-12 ng/ml for all patients. The comparison criteria included incidence of Over-immunosuppression (tacrolimus C0 >15 ng/ml), incidence of acute rejection and infectious complications in the first month after surgery, incidence and duration of delayed graft function (DGF), and length of stay at the hospital.Results. Over-immunosuppression was statistically significantly lower in the personalized protocol group, with 36.7% in group I and 87.5% in group II (p < 0.001). There was also a lower incidence of early infectious complications in group II: 5.4% vs. 13.2%, however, without reaching a level of statistical significance (p = 0.088). DGF incidence in group I and group II were 25.4% (58/228) and 22.7% (17/75), respectively. The length of stay at the hospital in group II was also statistically significantly lower: 13 versus 19 bed days (p = 0.033). In both subgroups, no patient developed acute rejection in the first month after surgery (p = 1).Conclusion. The personalized dosing protocol that was developed for extended-release tacrolimus in kidney recipients achieves the target levels of the drug recommended for the early postoperative period with low risk of under-immunosuppression and associated acute graft rejection, with a significantly lower incidence of over-immunosuppression.","PeriodicalId":21400,"journal":{"name":"Russian Journal of Transplantology and Artificial Organs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90058825","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}

Organ preservation parameters, length of stay in intensive care unit (ICU), severity of postoperative complications in primary transplantations in general and in the analyzed group did not differ significantly. The main causes of graft loss were graft arterial insufficiency (57.9%) and hepatic artery thrombosis (21%). Severe early allograft dysfunction (EAD) and primary nonfunction accounted for 10.5%, portal vein thrombosis occurred in 5%, and chronic graft rejection was noted in 5% of cases.Conclusion.

The retrospective study included 99 KTRs who received inpatient treatment for COVID-19 between September 1 and December 31, 2021. Patients were 52.0 ± 11.5 years old (M, 47.5%). Bamlanivimab/etesevimab combination drug at a dose of 700/1400 mg was used as mAbs. To evaluate the efficacy of mAbs therapy, two groups of patients were identified. Group 1 consisted of 33 KTRs who received mAbs as one of the therapy components, while group 2 consisted of 66 patients who received no mAbs. Discharge from the hospital or death was considered as the endpoint of follow-up.Results. In group 1, after the use of mAb, progression of pulmonary process was observed less frequently than in the control group with CT1-2 transformation to CT3-4 (9.1% vs. 30.3%, respectively, p < 0.01). Group 1 KTRs differed significantly from group 2 - lower need for ICU and ventilator care (6.1% vs. 27.3% and 3% vs. 19.8%, respectively). The groups were comparable by sex, age, body mass index, Charlson Comorbidity Index (CCI) and time after kidney transplant (KTx) at the onset of the disease and by rnseline blood biochemistry parameter values at the time of hospitalization. Only C-reactive protein (CRP) and fibrinogen values were higher in the non-mAbs patients who were hospitalized later in the course of the disease (7.7 ± 3.2 days versus 4.6 ± 1.6 days in group 1, p < 0 .001). The frequency of prescription of other therapies did not differ between the compared groups. Use of mAbs significantly reduced mortality from 19.7% in KTRs in group 2 to 3% in group 1 without adverse effect on graft function. Conclusion. The use of mAbs therapy in the early stages of COVID-19 in KTRs is safe, it prevents severe COVID-19, and reduces the incidence of adverse outcomes.","PeriodicalId":21400,"journal":{"name":"Russian Journal of Transplantology and Artificial Organs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76434343","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}
