Abstract:
Post-transplant diabetes mellitus (PTDM) is a common endocrine and metabolic disorder after adult solid organ transplant (SOT), affecting 10% to 40% of recipients. PTDM has been associated with increased mortality, heightened risk of infections, graft-related complications and cardiovascular diseases, all of which seriously threaten the quality of life and long-term survival of recipients. According to recent studies and the domestic healthcare system, this consensus provides a comprehensive overview of the epidemiology, risk factors, pathogenesis, screening and diagnosis, treatments, prevention strategies, cardiovascular risk factor management and microvascular complications associated with PTDM, in order to further standardize the diagnosis and treatment of PTDM. The objective is to standardize the comprehensive management of PTDM with the aim of enhancing the long-term quality of life and clinical outcomes for SOT recipients.

Abstract:
Kidney transplantation is the optimal treatment for patients with end-stage renal disease, whereas long-term survival of renal allografts remains a challenging issue. Renal ischemia-reperfusion injury (IRI) and rejection of renal allografts are considered as important influencing factors of long-term survival of renal allografts, which are regulated by innate and adaptive immune cells. Macrophages are one type of innate immune cells that could assist initiating adaptive immunity and are divided into M1, M2 and regulatory macrophages. Previous studies have revealed that M1 macrophages may aggravate renal IRI and acute T cell-mediated rejection (TCMR). However, M2 macrophages may mitigate renal IRI and acute TCMR, whereas it is positively correlated with antibody-mediated rejection (AMR). Regulatory macrophages are a special subgroup of macrophages, which may induce immune tolerance in organ transplantation and have promising clinical application prospects and basic scientific research value. In this article, the relationship among macrophage typing, macrophages and renal IRI, rejection of renal allografts, regulatory macrophages and immune tolerance was reviewed, and the potential mechanism was analyzed, aiming to induce changes in macrophage subtypes or eliminate specific subtypes of macrophages, thereby improving clinical prognosis of the recipients and long-term survival of renal allografts.

Abstract:
Renal ischemia-reperfusion injury (RIRI) is the main cause of acute kidney injury (AKI), which commonly occurs in surgery, severe trauma, shock and drug-induced kidney injury. At present, effective treatment for RIRI is still lacking. Oxidative stress is the major pathological injury mechanism of RIRI. Nuclear factor E2-related factor 2 (Nrf2) is the key transcription factor of anti-oxidative stress response, which may activate various cytoprotective genes related to redox and detoxification. Recent studies have shown that Nrf2 may play a protective role in the protection and treatment of RIRI by regulating oxidative stress, inflammation, cell apoptosis and autophagy, etc. Consequently, the structure and biological function of Nrf2, related signaling pathways, its role in the incidence and development of RIRI and potential mechanism were reviewed in this article, aiming to provide novel ideas for the prevention and treatment of RIRI.

Abstract:
Ferroptosis is a newly-emerged pattern of programmed cell death discovered in recent years, which is defined as iron-dependent programmed necrosis mediated by lipid peroxidation damage. As a conservative procedure, ferroptosis plays a vital role in the development and diseases of multiple organisms including plants and animals. Since ferroptosis was first reported in 2012, growing interests have been diverted to the process of ferroptosis and its role in disease treatment. Ischemia-reperfusion injury is a common pathological process during organ transplantation, and ferroptosis is considered as one of the main patterns inducing ischemia-reperfusion injury. Consequently, the definition, regulatory mechanism and the mechanisms of ferroptosis in ischemia-reperfusion injury after kidney, liver, heart and lung transplantations were reviewed, aiming to provide theoretical basis for the prevention and treatment of ischemia-reperfusion injury in organ transplantation.

Abstract:
Objective To evaluate the effect of body mass index (BMI) on early prognosis of the recipients after lung transplantation. Methods Clinical data of 307 lung transplant recipients were retrospectively analyzed. According to preoperative BMI, all recipients were divided into the low (BMI <18.5 kg/m2, n=114), normal (18.5 kg/m2≤BMI <24 kg/m2, n=145) and high (BMI≥24.0 kg/m2, n=48) BMI groups, respectively. Baseline data including age, sex, blood type, BMI, preoperative complications, preoperative pulmonary hypertension, and intraoperative use of extracorporeal membrane oxygenation (ECMO) of all recipients were compared among three groups. The survival rate of all recipients was estimated by Kaplan-Meier curve and the survival curve was delineated. The differences of survival rate were analyzed by log-rank test. The 30-, 90- and 180-d mortality risk of all recipients after lung transplantation in different BMI groups was compared by multivariate Cox regression analysis. Results There were significant differences in age and sex of recipients among three groups (both P<0.05). There was a significant difference regarding the 180-d survival rate after lung transplantation among different BMI groups (P<0.05). Multivariate Cox regression analysis showed that the 90-d mortality risk after lung transplantation in the high BMI group was 2.295 times higher than that in the normal BMI group [hazard ratio (HR) 2.295, 95% confidence interval (CI) 1.064-4.947, P=0.034]. In the high BMI group, the 180-d mortality risk after lung transplantation was 2.783 times higher compared with that in the normal BMI group (HR 2.783, 95%CI 1.333-5.810, P=0.006), and the 180-d mortality risk in the low BMI group was 2.181 times higher than that in the normal BMI group (HR 2.181, 95%CI 1.124-4.232, P=0.021). Conclusions Compared with the recipients with normal BMI, their counterparts with high and low preoperative BMI have higher mortality risk early after lung transplantation. Adjusting preoperative BMI to normal range contributes to improving early prognosis of lung transplant recipients.

Abstract:
Objective To analyze the changes of postoperative pulmonary function in lung transplant recipients. Methods Clinical data of 81 recipients undergoing bilateral lung transplantation and combined heart-lung transplantation were collected, and postoperative status of the recipients was analyzed. Pulmonary ventilation and diffusion function indexes at 1 month, 3 months, every 3 months (3-18 months after lung transplantation) and every 6 months (18-36 months after lung transplantation) were analyzed in the recipients. The characteristics of the optimal pulmonary function in the recipients were assessed. Results Postoperative mechanical ventilation time was 4 (2, 9) d, and the length of postoperative ICU stay was 10 (7, 20) d. Among 81 recipients, 27 recipients developed primary graft dysfunction (PGD) after lung transplantation, with an incidence rate of 33%. Postoperative forced vital capacity (FVC) to predicted value ratio (FVC%pred), forced expiratory volume in one second (FEV1) to predicted value ratio (FEV1%pred), FEV1/FVC to predicted value ratio (FEV1/FVC%pred) and corrected diffusion lung capacity for CO to predicted value ratio (DLCOc%pred) were changed over time (all P<0.001). FVC%pred and FEV1%pred were gradually increased within postoperative 9 months, and DLCOc%pred was gradually elevated within postoperative 3 months (all P<0.05). Thirty-six recipients had FVC%pred≥80%, FEV1%pred≥80% in 41 cases, FEV1/FVC%pred≥92% in 76 cases, FVC%pred≤40% in 1 case and FEV1%pred≤40% in 1 case, respectively. Sixteen recipients had DLCOc%pred≥80%, corrected diffusion lung capacity for CO/alveolar volume to predicted value ratio (DLCOc/VA%pred) ≥80% in 63 cases, DLCOc%pred≤40% in 4 cases and DLCOc/VA%pred≤40% in 1 case, respectively. Postoperative FVC%pred, FEV1/FVC%pred and DLCOc%pred in recipients with a primary disease of obstructive pulmonary disease were significantly higher than those in their counterparts with restrictive pulmonary disease (all P<0.05). Postoperative DLCOc%pred in recipients with PGD was significantly lower than that in those without PGD (P<0.05). Conclusions Pulmonary ventilation function in lung transplant recipients reaches the optimal state and maintains a steady state at postoperative 9 months, and pulmonary diffusion function reaches a steady state at postoperative 3 months. Primary diseases and the incidence of PGD may affect postoperative pulmonary function.

Abstract:
Objective To investigate the attitudes and influencing factors of transplantation-related populations towards kidney xenotransplantation. Methods From June 2022 to January 2023, stratified random sampling was performed from patients awaiting kidney transplantation, patients after kidney transplantation, patients' relatives and medical students. Four hundred subjects were collected from each population and 1600 subjects were investigated using a self-designed questionnaire. Baseline data of the respondents, their attitudes towards kidney xenotransplantation and the reasons of rejecting kidney xenotransplantation were analyzed. The influencing factors of attitudes towards kidney xenotransplantation were also identified. Results A total of 1 493 valid questionnaires were collected, and the questionnaire retrieval rate was 93.31%. About 93.10% of the respondents accepted allogeneic kidney transplantation, and 66.78% had heard of kidney xenotransplantation. Seven hundred and ninety-five respondents suggested that they could accept kidney xenotransplantation "when kidney xenotransplantation and allogeneic kidney transplantation yielded the same results and risks". Six hundred and ninety-eight respondents indicated that they were "unable" or "uncertain" whether they could accept kidney xenotransplantation (χ2=16.409, P=0.001). Among these 698 respondents, the proportion of them who were willing to accept kidney xenotransplantation when they did not meet the conditions of allogeneic kidney transplantation was 10.9%. About 35.8% of respondents were willing to accept kidney xenotransplantation if it yielded less risk and better prognosis compared with allogeneic kidney transplantation. If the time of awaiting kidney xenotransplantation was shorter than that of allogeneic kidney transplantation, 21.2% were willing to accept kidney xenotransplantation. If the cost of kidney xenotransplantation was less than that of allogeneic kidney transplantation, 24.5% of them were willing to accept kidney xenotransplantation. The main reasons of rejecting kidney xenotransplantation included surgical risk and other unknown risks. Multivariate analysis showed that respondents residing in cities and towns for a long period of time, those who accept allogeneic kidney transplantation and those who have heard of kidney xenotransplantation showed more positive attitudes towards kidney xenotransplantation. Conclusions Different transplantation-related populations have different attitudes towards kidney xenotransplantation, and the overall attitudes are positive. Active promotion of kidney xenotransplantation research and carrying out relevant popular science education contribute to improving public attitudes towards the acceptance of kidney xenotransplantation.

Abstract:
Objective To identify the risk factors of new-onset hypertriglyceridemia (HTG) in kidney transplant recipients. Methods Clinical data of 149 kidney transplant recipients were retrospectively analyzed. According to serum triglyceride (TG) level after operation, they were divided into the non-HTG group (TG≤1.7 mmol/L, n=60) and new-onset HTG group (TG>1.7 mmol/L, n=89). Baseline data of all recipients were compared between two groups. The risk factors of HTG in kidney transplant recipients were analyzed by generalized estimating equation (GEE), and validated by multiple regression equations. Results No significant differences were observed in baseline data between two groups (all P>0.05). Multivariate analysis showed that the incidence of HTG in the middle and high tacrolimus (Tac) concentration groups was higher than that in the low Tac concentration group [odds ratio (OR) 3.11, 95% confidence interval (CI) 1.22-7.93, P=0.018 in the middle Tac concentration group; OR 5.11, 95%CI 1.31-19.98, P=0.019 in the high Tac concentration group]. Compared with type-A blood recipients, the risk of new-onset HTG was significantly increased in type-O blood counterparts (OR 2.77, 95%CI 1.14-6.71, P=0.024). The risk of new-onset HTG was decreased along with the increase of preoperative globulin level (OR 0.93, 95%CI 0.87-0.99, P=0.043). At postoperative 3 months, Tac blood concentration in the new-onset HTG group was significantly higher compared with that in the non-HTG group, and significant difference was observed (P<0.05). Multiple regression equations confirmed that the risk of new-onset HTG in type-O blood kidney transplant recipients was higher than that in type-A blood counterparts, and the risk of new-onset HTG in the middle and high Tac concentration groups was higher than that in the low Tac concentration group (all P<0.05). Conclusions Type-O blood kidney transplant recipients are more prone to HTG. It is necessary to strengthen postoperative monitoring and control of blood lipids. The blood concentration of Tac probably affects the new-onset HTG in kidney transplant recipients. Maintaining an appropriate blood concentration of Tac may be beneficial to lowering the risk of HTG.

Abstract:
Objective To investigate the epidemiological characteristics of SARS-CoV-2 pneumonia in kidney transplant recipients and analyze the risk and protective factors of severe/critical infection with SARS-CoV-2. Methods Clinical data of 468 kidney transplant recipients infected with SARS-CoV-2 were retrospectively analyzed. According to the severity of infection, they were divided into mild SARS-CoV-2 infection recipients (n=439) and SARS-CoV-2 pneumonia group (n=29). Among the 439 mild SARS-CoV-2 infection recipients, 87 recipients who were randomly matched with their counterparts in the SARS-CoV-2 pneumonia group according to sex, age and transplantation time at a ratio of 3∶1 were allocated into the mild SARS-CoV-2 infection group. Twenty-nine recipients in the SARS-CoV-2 pneumonia group were divided into the moderate SARS-CoV-2 pneumonia group (n=21) and severe/critical SARS-CoV-2 pneumonia group (n=8). Baseline data of all recipients were collected. The risk and protective factors of SARS-CoV-2 infection in kidney transplant recipients were identified. Results The proportion of recipients complicated with 2-3 types of complications in the SARS-CoV-2 pneumonia group was higher than that in the mild SARS-CoV-2 infection group, and the proportion of recipients treated with tacrolimus(Tac)+mizoribine+glucocorticoid immunosuppression regimen in the SARS-CoV-2 pneumonia group was lower than that in the mild SARS-CoV-2 infection group, and significant differences were observed (both P<0.05). In 29 kidney transplant recipients with SARS-CoV-2 pneumonia in the SARS-CoV-2 pneumonia group, white blood cells, the absolute values of lymphocytes, eosinophils, total T cells, CD4+T cells and CD8+T cells, and serum uric acid levels were significantly lower, whereas ferritin levels were significantly higher than the values prior to SARS-CoV-2 pneumonia, and significant differences were observed (all P<0.05). Compared with the moderate SARS-CoV-2 pneumonia group, the proportion of recipients with hypoxemia was higher, the proportion of recipients treated with Tac/ciclosporin (CsA)+mycophenolate mofetil+glucocorticoid immunosuppression regimen was higher, and the proportion of recipients administered with 2-3 doses of SARS-CoV-2 vaccine was lower in the severe/critical SARS-CoV-2 pneumonia group, and significant differences were observed (all P<0.05). Conclusions More complications and immunosuppression regimen containing mycophenolate mofetil are the risk factor for SARS-CoV-2 infection in kidney transplant recipients. Vaccination with SARS-CoV-2 vaccine and immunosuppression regimen containing mizoribine are probably the protective factors for lowering the risk of SARS-CoV-2 infection. The levels of inflammatory cytokines are associated with the severity of SARS-CoV-2 pneumonia.

Abstract:
Objective To summarize the diagnosis and treatment experience of portal vein aneurysm after liver transplantation. Methods Clinical data of two recipients with portal vein aneurysm after liver transplantation were retrospectively analyzed. Clinical features, diagnosis, treatment and prognosis were summarized based on literature review. Results Both two cases were diagnosed with intrahepatic portal vein aneurysm complicated with portal vein thrombosis and portal hypertension after liver transplantation. Case 1 was given with targeted conservative treatment and he refused to undergo liver retransplantation. Physical condition was worsened after discharge, and the patient eventually died from liver graft failure, kidney failure, lung infection, and septic shock. Case 2 received high-dose glucocorticoid pulse therapy, whereas liver function was not improved, and the patient was recovered successfully after secondary liver transplantation. Conclusions Long-term complication of portal vein aneurysm (especially intrahepatic type) after liver transplantation probably indicates poor prognosis. Correct understanding, intimate follow-up and active treatment should be conducted. Liver retransplantation may be a potential treatment regimen.

Abstract:
Objective To construct a scientific and rational post competency model of human organ donation coordinators. Methods Based on the onion model, the index pool was initially constructed by literature research and behavioral event interview. The index system was screened, modified and improved using Delphi method. The weight of indexes at all levels was determined by analytic hierarchy process. Results The effective response rates of two rounds of Delphi expert inquiries were both 100%, indicating that the expert opinions were highly dependable. The experts' judgment coefficient (Ca), familiarity (Cs) and authoritative coefficient (Cr) were all above 0.7, indicating that the experts' opinions were highly reliable. The expert coordination coefficients (W) were 0.294 and 0.342 (both P<0.001), indicating that experts delivered coordinated opinions and yielded slight difference in understanding the importance of indexes. Finally, according to the "onion model" theory and experts' opinions, a set of coordinator's post competency model including 6 first-level and 55 second-level indexes was established, which comprised an index surface layer, a middle layer and a core layer. Among them, the core layer represented core professional values, the middle layer was personal quality and professional ethics and quality, and the surface layer was interpersonal communication capability, organizational cooperation capability and professional knowledge and lifelong learning capability. Conclusions The post competency model of organ donation coordinators established in this study consists of 6 first-level and 55 second-level indexes, which is highly effective and reliable.

Abstract:
Ischemia-reperfusion injury, rejection, nephrotoxicity caused by calcineurin inhibitors and other factors cause excessive accumulation of renal extracellular matrix after kidney transplantation, which gradually induce renal fibrosis and eventually lead to renal failure. In recent years, the mechanism of macrophages in renal allograft fibrosis has gradually captivated widespread attention. Studies have shown that some drugs like mammalian target of rapamycin inhibitors may mitigate renal allograft fibrosis through the macrophage. In this article, the main pathogenesis and pathophysiological mechanism of renal allograft fibrosis, the role of different macrophages in the progression of renal allograft fibrosis, the infiltration of peripherally-recruited macrophages and renal resident macrophages into renal injury areas, the induction of myofibroblasts by macrophages and potential treatment regimens of macrophage-associated renal allograft fibrosis were reviewed, aiming to provide reference for investigating the role of macrophages in renal allograft fibrosis.

Abstract:
Human leukocyte antigen (HLA) is a product encoded by HLA gene complex, which is located on the short arm of chromosome 6 and is the main target of alloimmunity. However, positive HLA antibody is not responsible for all kinds of rejections in kidney transplantation. Non-HLA antibody is the product of donor gene expression in allogeneic kidney transplantation. Intraoperative ischemia-reperfusion injury, the interaction between alloimmunity and autoimmunity and the mediation of extracellular vesicles may trigger immune system response and promote the production of non-HLA antibody. Multiple studies have demonstrated that non-HLA antibody is an important factor of inducing rejection and affecting the outcomes of kidney transplantation. Consequently, the types and formation mechanism of non-HLA antibody in kidney transplantation were reviewed, and research progress on kidney transplantation rejection associated with non-HLA antibody was summarized, aiming to provide reference for in-depth study of kidney transplantation rejection associated with non-HLA antibody.

Abstract:
Prevention and treatment of complications after liver transplantation play a significant role in maintaining liver graft function and improving clinical prognosis of the recipients. Neutrophil extracellular trap (NET) are fibrous net-like structures composed of DNA as the skeleton and histones and granular proteins released by activated neutrophils. Studies have shown that the activation of neutrophils and the release of NET in donor liver after liver transplantation are involved in the incidence of multiple liver transplantation-related complications including ischemia-reperfusion injury, acute rejection, acute liver failure and recurrence of hepatocellular carcinoma, etc. In this article, the effect of NET on the complications after liver transplantation was mainly assessed, and research progress on NET as a potential target for the prevention and treatment of complications after liver transplantation was reviewed, aiming to provide reference for the prevention and treatment of complications after liver transplantation, enhance clinical efficacy of liver transplantation and improve clinical prognosis of the recipients.

Studies have shown that the activation of neutrophils and the release of NET in donor liver after liver transplantation are involved in the incidence of multiple liver transplantation-related complications including ischemia-reperfusion injury, acute rejection, acute liver failure and recurrence of hepatocellular carcinoma, etc. In this article, the effect of NET on the complications after liver transplantation was mainly assessed, and research progress on NET as a potential target for the prevention and treatment of complications after liver transplantation was reviewed, aiming to provide reference for the prevention and treatment of complications after liver transplantation, enhance clinical efficacy of liver transplantation and improve clinical prognosis of the recipients.

Abstract:
Regulatory T cells (Treg) are important inhibitory immune cells to establish immune tolerance, which play a pivotal role in regulating excessive immune response and autoimmune diseases of the host. Previous studies related to transplant immune tolerance have confirmed that increasing the number of Treg in vivo or enhancing the function of Treg serve as a therapeutic strategy to induce transplant immune tolerance. At present, Treg-based induction methods for transplant immune tolerance include adoptive infusion of Treg, in vivo amplification of Treg and utilization of antigen-specific Treg. In this article, the characteristics and mechanism of Treg, the latest research progress on basic experiments and clinical practice of Treg related to transplant immune tolerance at home and abroad were reviewed, and future challenges and development of Treg therapy were prospected, aiming to unravel the significance and application prospect of Treg in transplant immune tolerance, explore the advantages and limitations of Treg therapeutic strategies, and provide reference and evidence for subsequent research in this field.

Abstract:
Organ transplantation is the most effective treatment for various types of end-stage diseases. To resolve the problem of donor shortage in organ transplantation, the possibility of xenotransplantation has been gradually explored by surgeons. Pig is one of the common donor sources for xenotransplantation. As a bridge between two species, the viruses carried by pig organs may be transmitted between species and cause the risk of zoonosis. Porcine endogenous retrovirus (PERV) is integrated into the genome, which is a category of retrovirus featuring cross-species transmission. In this article, the influencing factors of transmission characteristics of PERV, the transmission risk of PERV and its recombinant virus, and the detection and transmission risk assessment of PERV in xenotransplantation test were reviewed, aiming to provide reference for alleviating severe shortage of donor organs and driving the advancement of xenotransplantation technologies.

Abstract:
Ureteral stricture in renal allografts is one of the common postoperative complications in kidney transplant recipients. Due to short ureter in renal allografts, endovascular treatment should be adopted before reconstruction surgery to avoid irreversible injury. Alleviating renal allograft injury, easing obstruction or establishing drainage channel are the key measures to treat ureteral stricture. In endovascular treatment, balloon dilatation and internal incision yield high recurrence rate, and long-term indwelling of self-expanding metallic ureteral stents may be a better option. Compared with traditional stents, metallic stents may maintain urinary tract patency for a long time and mitigate the irritation of lower urinary tract symptoms,with different indications and efficacy. Although all metallic stents may be displaced and occluded, it still plays a positive role in the treatment of ureteral stricture in renal allografts. In this article, the application of self-expanding metallic ureteral stent in ureteral stricture of renal allografts was mainly illustrated, aiming to provide reference for optimizing the treatment of ureteral stricture in renal allografts.
