Abstract

Introduction. The total number of pancreas transplantations performed in Russia by the end of 2019 had been 176. There are no detailed reports on the number and results of pancreas transplantation in Russia with analysis of factors that significantly affect outcomes.
Material and methods. This article presents a retrospective analysis of 60 pancreas transplantation results, which had been performed from January 2008 to July 2019 at the N.V. Sklifosovsky Research Institute for Emergency Medicine. In addition, the assessment of factors that significantly affect the outcomes of pancreas transplantations was performed.
Results. 17 intra-abdominal pancreas transplantations with duodenoejunoanastomosis and 43 retroperitoneal pancreas transplantations with interduodenal anastomosis were performed. In 52 patients, the pancreas graft after vascular reconstruction with a Y-shaped vascular prosthesis was used; in other 8 patients, the pancreas graft with isolated blood flow through the splenic artery was used. The rates of immunological and surgical complications were 23.3% and 56.7%, respectively. In-hospital and 1-year recipient, kidney and pancreas graft survival rates were 88.3%, 86.4%, 83.3% and 86.6%, 84.8%, and 81.7%, respectively. The factors that significantly affected the outcomes of pancreas transplantation were the conversion of the dialysis therapy modality, the development of parapancreatic infection, repeated open surgical interventions, surgical complications of IIIb-IVa severity grades by Clavien-Dindo Classification, some features of basic and induction immunosuppressive therapy.
Conclusion. The results of pancreas transplantation at the N.V. Sklifosovsky Research Institute for Emergency Medicine are comparable to the outcomes of pancreas transplantation in most world transplant centers.

Abstract

The aim was to study the results of using various treatment regimens for hepatic encephalopathy for patients with liver cirrhosis before and after liver transplantation and the effect on the incidence and severity of hepatic encephalopathy in the perioperative period, and on the posttransplantation course.
Material and methods. Fifty four patients with cirrhosis of various etiologies and the presence of significant hepatic encephalopathy undergoing living donor liver transplantation were included in the study. In the comparison group, patients took lactulose and rifaximin. In the main group, patients took lactulose and rifaximin in combination with L-ornithine-L-aspartate in the preoperative period, and L-ornithine-L-aspartate after liver transplantation for 5 days.
Results. The use of L-ornithine-L-aspartate in the complex therapy of hepatic encephalopathy led to significantly reduced time of performing the Number Connection Test, the improvement of cognitive functions in patients by the Montreal Cognitive Assessment, a decreased incidence of stage II–III hepatic encephalopathy and an increased incidence of stage 0-I hepatic encephalopathy in the preoperative period. In the postoperative period, patients of the main group showed a rapid decrease in the severe stages of hepatic encephalopathy (stage II–III) towards less severe forms (stage 0–I) on the 3rd, 5th and 7th days after liver transplantation, and also a faster recovery of cognitive functions, an earlier adequate recovery of consciousness, muscle tone, an earlier possibility of extubation, a shorter length of stay in the intensive care unit, and a decreased postoperative hospital length of stay relatively to the patients of the comparison group.
Conclusion. The use of L-ornithine-L-aspartate in the combination therapy for hepatic encephalopathy in the peritransplantation period leads to a significant decrease of the incidence and severity of hepatic encephalopathy, accelerates rehabilitation of patients, reduces postoperative hospital length of stay.

Abstract

Introduction. Recently, researchers have paid considerable attention to the strategy of intraoperative infusiontransfusion therapy in traumatic surgical interventions. The choice of a “restrictive” regimen during surgery in many studies has reduced the incidence and severity of intra- and postoperative complications.
Objective. Comparison of the effectiveness of "liberal" and "restrictive" intraoperative infusion-transfusion therapy in lung transplantation.
Material and methods. The study included 58 patients who underwent bilateral lung transplantation at N.V. Sklifosovsky Research Institute for Emergency Medicine in the period 2012-2019. The patients were divided into 2 groups: the comparison group included 31 patients, the total volume of intraoperative infusion-transfusion in whom was 14386.9 ± 1310.0 ml (16.5 ml/kg/h). Group II consisted of 27 patients; their total volume of intraoperative infusion-transfusion during surgery was 10251.3 ± 740.1 ml (12.9 ml/kg/hour). The analysis we performed included the volume and composition of intraoperative infusion-transfusion therapy, the volume of blood loss, clinical and laboratory data, the duration of mechanical ventilation, the frequency of intraoperative use of veno-arterial extracorporeal membrane oxygenation and the duration of its use after surgery, mortality.
Results. When using the "restrictive" fluid therapy for lung transplantation, we observed a decrease in the volume of intraoperative blood loss by 1.3 times, the volume of transfusion of blood components, including fresh frozen plasma by 37%, erythrocyte suspension by 3.1 times, and instrumental reinfusion of autoerythrocytes by 1.56 times. At the same time, we revealed a decrease by 2.7 times in the duration of the mechanical ventilation use, a decreased frequency of using veno-arterial extracorporeal membrane oxygenation during surgery by 1.3 times, and a decreased duration of using veno-arterial extracorporeal membrane oxygenation after surgery by 2.3 times. Mortality was 38.7% in group I, and 30.7% in group II.
Conclusion. The “restrictive” approach to intraoperative infusion-transfusion therapy in lung transplantation seems a promising new trend requiring further study and gaining the experience.

Abstract

Introduction. Despite the improvements in immunosuppressive therapy, the growing number of repeat kidney transplantations and associated risks of acute rejection make it relevant to assess the impact of early acute rejection on a long-term kidney graft survival.
Objective. The aim of the study was to evaluate the rate, the clinical aspects of early acute rejection after repeat kidney transplantation and the outcomes of its treatment, to perform the assessment of the impact of rejection episodes on a long-term kidney graft survival.
Material and methods. We carried out the retrospective analysis of kidney graft survival after 121 repeat kidney transplantations performed in N.V. Sklifosovsky Research Institute for Emergency Medicine in the period from 2007 to 2018. Group I included 96 recipients after kidney transplantation without acute rejection in postoperative period. Group II consisted of 25 patients with early acute rejection after kidney transplantation. We performed the assessment of the impact of early acute rejection on the kidney graft survival in comparison with recipients with uncomplicated postoperative period. Statistical processing was carried out by nonparametric methods. Survival was assessed using the Kaplan–Meier curves.
Results. 1-year and 3-year kidney graft survival rates amounted to 90.3% (95%, confidence interval 85–95) and 85.4% (95%, CI 79–91), respectively, in recipients of Group I; and 72% (95%, CI 58–86) and 60% (95%, CI 46–76) in patients of Group II. Significant differences in 1-year and 3-year kidney graft survival between patients of Group I and II have been noticed (P=0.0022 and P=0.0065, respectively).
Conclusions. Patients with early acute rejection after kidney transplantation had poorer kidney graft survival in comparison with patients without rejection episodes in postoperative period.

Abstract

Introduction. One of the serious complications after transplantation of solid organs and bone marrow is the development of post-transplant lymphoproliferative diseases.
Clinical case. To evaluate the course of post-transplant lymphoproliferative diseases in the long-term in a liver transplant recipient after conversion of immunosuppressive therapy from tacrolimus to everolimus. We analyze a case of generalized primary plasmacytoma of lymph nodes with bone marrow involvement in a patient after liver transplantation.
Results. After conversion of immunosuppression we observed a rapid positive trend: decreasing size of lymph nodes and regression of the level of paraprotein down to its complete disappearance. There were neither adverse events associated with everolimus for four years, nor signs of immunosuppression insufficiency.
Conclusion. This Case Report is the first description of a long-term remission of nodal plasmacytoma that developed in a liver transplant recipient after complete withdrawal of calcineurin inhibitors and administration of everolimus. We suggest that the regression of post-transplant lymphoproliferative diseases after replacing calcineurin inhibitors with everolimus is associated not only with the minimization of calcineurin inhibitors exposure, but also with the antitumor effect of the everolimus itself, which prompts us to discuss the possibilities of expanding its clinical application.

Abstract

The authors have presented the review of scientific literature on producing grafts intended for surgical reconstruction of ligament ruptures. The treatment of ligament ruptures in reconstructive plastic surgery could be performed by using synthetic grafts, autologous and allogenic grafts from tissue donors. Advantages of synthetic grafts include the possibility of their regular manufacturing under sterile conditions, and providing mechanical properties, high biocompatibility. However, synthetic implants significantly increase the risk of synovitis and other complications, they can not be replaced by the native tissue, and have no ability to regeneration. Autologous grafts have ideal tissue compatibility and quick biointegration, could be harvested from different anatomical sites, but commonly the graft harvesting is followed by donor site morbidity and potential risk of injury nerves, elongates operation time, bad cosmetic results. The use of autografts may be also limited by anatomical features of the patient. Allogenic ligament biomaterial could provide wide range of grafts, but in our days there is no standardized methods for ligament graft sterilization and long storage. Wellknown sterilization methods, such as ionized radiation and chemical treatment, gave controversial results. One could conclude that estimation of ligament graft viability must include a complex study of biomechanical properties, cell and fibers integrity.

Abstract

The analysis of literature on experimental and clinical transplantation for the period of the 1968–1969 demonstrated that in the period from 1960 to 1970 the world transplantation saw a paradigm change in the field of homoorgan transplant: instead of overcoming the incompatibility between the donor organ and the recipient's body by using biological and physiological methods to influence the organ, which V.P. Demikhov had been dealing with for many years; surgeons and scientists, first abroad, and then in the USSR started developing and applying the creation of artificial immunological tolerance by using various physical, chemical and biological methods to impact recipient's body. The change of paradigms significantly influenced the implementation of organ transplantation techniques in clinic, including those of vital organs, and the further development of clinical transplantology. The data on the first heart transplants in 1968 and lung transplants in 1963–1970 have been presented.
