Since the end of 2019, the SARS-CoV-2 infection pandemic has swept the world. Although the current SARS-CoV-2 mutants have decreased in pathogenicity and virulence compared with the original strains, and most patients have a good prognosis, the solid organ transplant (SOT) recipients are vulnerable to SARS-CoV-2. And even with vaccination, the risk of hospitalization or death is still high in SOT recipients infected with SARS-CoV-2. What's more, the clinical manifestations, diagnosis and treatment strategy of SOT recipients infected with SARS-CoV-2 has its unique features, which needs high attention. At present, there is a lack of guidelines or consensus in the diagnosis and treatment field of SARS-CoV-2 for such a large number of SOT recipients. Therefore, referring to the "Diagnosis and treatment regimen for SARS-CoV-2 infection (Trial Version 10)" and global published literature, the writing team wrote the "Expert consensus on diagnosis and treatment of SARS-CoV-2 infection in solid organ transplantation recipients (2023 edition)". This consensus was evidence-based written and reached by experts after multiple rounds of discussions, forming 21 recommendations, providing reference for the diagnosis and treatment of SOT recipients infected with SARS-CoV-2.
Due to long-term use of immunosuppressive agents, solid organ transplant recipients (SOTR) belong to high-risk populations of multiple pathogenic infection, including SARS-CoV-2. In addition, SOTR are constantly complicated by chronic diseases, such as hypertension and diabetes mellitus, etc. After infected with SARS-CoV-2, the critically ill rate and fatality of SOTR are higher than those of the general population, which captivates widespread attention from experts in the field of organ transplantation. Omicrone variant is currently the significant pandemic strain worldwide, rapidly spreading to more than 100 countries worldwide and causing broad concern. According to the latest international guidelines on the diagnosis and treatment of SARS-CoV-2 infection and relevant expert consensus in China combined with current domestic situation of SARS-CoV-2 pandemic and China's "diagnosis and treatment regimen for SARS-CoV-2 infection (Trial Version 10)", the epidemiology, clinical manifestations and prognosis, diagnosis, clinical classification and treatment of SARS-CoV-2 infection were briefly reviewed.
The hosts could show complex and diverse immune responses to the allografts. Whether biomarkers can be employed to explain the complexity of graft immune responses and the degree of disease damage are of significance. Conventional biomarkers, such as estimated glomerular filtration rate and blood concenrtation of immunosuppressant, lack of sensitivity and specificity in accurately identifying between immune and non-immune renal allograft injuries. Although renal biopsy is the "gold standard" for the diagnosis of postoperative complications, it still has disadvantages, such as invasiveness and high price, etc. Emerging biomarkers have potential advantages in the non-invasive diagnosis of subclinical injury of renal allograft, prediction of treatment response and individualized adjustment of immunosuppressive regimen. In this article, emerging biomarkers including blood, urine and tissue biomarkers that have been applied and are expected to be applied in clinical practice in the field of kidney transplantation were reviewed, and the range of application and effect of these biomarkers were evaluated, aiming to promote appropriate and rational application of these promising emerging biomarkers in clinical practice.
As an effective treatment for end-stage liver disease, liver transplantation has been widely carried out worldwide and gradually captivated widespread recognition. With the advancement of liver transplantation techniques, the incidence of postoperative complications has been gradually declined, and the short-term and long-term prognosis of recipients have been constantly improved. However, a huge gap has existed between the supply and demand of donor organs, which is a major factors restricting the development of liver transplantation. The amount of liver transplantation operation in China is increasing year by year, the shortage of donor liver is becoming more and more prominent, and marginal donor liver is increasingly used in clinic. In recent years, the selection criteria of donor organs, organ preservation and functional maintenance have been continuously improved. In this article, the application and development trend of different techniques were reviewed from the perspectives of donor liver preservation and functional maintenance, and recent technical development and research results were summarized, aiming to provide reference for further enhancing the survival rate of grafts and recipients and promoting the development of liver transplantation in China.
Islet transplantation is a promising treatment of diabetes mellitus and its complications. Nevertheless, dysfunction post-transplantation, rejection and shortage of donors are the bottleneck issues in the field of islet transplantation. Optimizing the preservation method of pancreas plays a positive role in obtaining a sufficient quantity of effective islets and maintaining their functions. During the culture stage, anti-rejection and anti-apoptosis treatment of islets, including mesenchymal stem cell (MSC), MSC-derived exosomes, anti-apoptosis drugs and gene modification, may become major approaches for islet protection and functional maintenance in clinical islet transplantation. Use of anti-instant blood-mediated inflammatory reaction (IBMIR) drugs after islet transplantation also plays a critical role in protecting islet function. In this article, the whole process from islet preparation to islet transplantation was illustrated, and relevant strategies of islet protection and functional maintenance were reviewed, aiming to provide reference for improving the quality of donors to compensate for the shortage of absolute quantity of donors and elevating the efficiency of islet transplantation.
As the final resolution for end-stage lung disease, lung transplantation can not only significantly prolong the survival, but also remarkably improve the quality of life of recipients. In recent decades, with the advancement of surgical techniques, immunosuppressants and post-transplantation management, the quantity of lung transplantation has been surged around the globe. However, the shortage of donor lung has severely restricted the development of lung transplantation. It is necessary to develop innovative approaches to expand the donor pool. The number of donors and effective preservation and functional maintenance of potential donor lungs play a key role in expanding the donor pool. The quality of donor lung is a critical precondition to ensure the long-term survival of lung transplant recipients. Preservation and functional maintenance of donor lung are of significance for guaranteeing the quality of lung allograft. In this article, research progresses on the management and maintenance of donor lung before procurement, the procurement of donor lung and the preservation and functional maintenance of lung allograft were reviewed, aiming to provide reference for the development of lung transplantation in clinical practice.
Diarrhea is a frequent complication after kidney transplantation, which is a common clinical manifestation of prevalent diseases following multiple types of organ transplantation. The common causes of diarrhea after kidney transplantation include adverse reactions of immunosuppressants, infectious diseases and de novo postoperative inflammatory bowel disease, etc. Diarrhea could seriously affect the quality of life of kidney transplant recipients, and may lead to allograft dysfunction or even death of recipients. Because the causes of diarrhea after kidney transplantation are complicated and probably overlap with each other, along with individual differences among recipients, the etiological diagnosis and targeted treatment of diarrhea after kidney transplantation should follow the principles of gradual and phased treatment. In this article, the epidemiology and harm, common causes and management strategies of diarrhea after kidney transplantation were summarized, aiming to deepen the clinicians' understanding and enhance the diagnosis and treatment levels of diarrhea after kidney transplantation, thereby improving the quality of life and prognosis of kidney transplant recipients.
Heart transplantation is one of the most effective strategies to treat end-stage heart failure. Multiple challenges, such as difficulty in preservation of heart allograft, rejection and postoperative complications, emerge in heart allotransplantation. After decades of research and practice, most problems have been resolved. Nevertheless, the shortage of donor organs has become increasingly prominent. To alleviate the shortage of donor organs, artificial heart and heart xenotransplantation have captivated attention, and obtained significant progress in recent years. The application of artificial heart in clinical practice has significantly enhanced the survival rate of patients with end-stage heart failure, which is expected to become the standard treatment for end-stage heart failure. Heart xenotransplantation still faces many challenges, which is still far from clinical application. In this article, the history of heart transplantation, development of heart allotransplantation, use of artificial heart and research progress on heart xenotransplantation were reviewed, and the future development direction of heart transplantation was predicted.
Antiviral therapy for chronic hepatitis C virus (HCV) infection has entered the era of direct antiviral agent (DAA), and up to 95% of patients could be clinically cured. Under this circumstance, HCV infection has gradually changed from relative contraindication to surgical indication for kidney transplantation. However, at present, the number of kidney transplantation from HCV-infected donors or recipients has been rarely reported in China. The short-term follow-up data of HCV-negative recipients undergoing kidney transplantation from HCV-positive renal allografts in other countries have confirmed that DAA yields high cure rate and safety in the treatment of HCV infection, and recipients could obtain favorable short-term survival and allograft outcome. However, the long-term safety of HCV-infected kidney transplantation remains to be validated by clinical trials with large sample size and long-term follow-up. In this article, the virological clearance, allograft outcome and safety of DAA use in HCV-negative recipients undergoing kidney transplantation from HCV-positive renal allografts under the intervention of DAA were investigated, aiming to evaluate clinical safety and efficacy of this pattern of kidney transplantation and deepen the understanding of safe use of HCV-positive organs.
Limb replantation and transplantation is the optimal treatment for traumatic limb amputation. Safe and effective limb preservation is the key factor to determine the success of limb replantation and transplantation. Currently, static cold storage is the gold standard of limb preservation. However, the preservation time is short, which may no longer meet clinical requirements. With rapid development of organ preservation in recent years, novel preservation technologies, such as ultra-low temperature preservation, supercooling preservation and mechanical perfusion preservation, have successively emerged. However, at present, these techniques are primarily applied to the preservation of solid organs rather than composite tissue allografts with blood vessels including limbs. In this article, research status and progress on the application of static cold storage and mechanical perfusion preservation in limb preservation were reviewed, aiming to provide reference for clinical application of limb preservation technology and promote the development of limb replantation and transplantation.
Ischemia-reperfusion injury after lung transplantation is the main cause of primary graft dysfunction, which will subsequently reduce the function of lung allograft and lower the overall survival rate of lung transplant recipients. As a physiological regulatory molecule, hydrogen molecule has the functions of anti-inflammation, easing oxidative stress, alleviating direct cell injury and mitigating epithelial edema. Recent studies have demonstrated that hydrogen molecule and its products (hydrogen and hydrogen-rich solution) could significantly mitigate ischemia-reperfusion injury and postoperative complications after lung transplantation. In this article, the protective effect and exact mechanism of hydrogen molecule and its products in lung transplantation were reviewed, aiming to provide theoretical basis for the application of hydrogen molecule and its products as a novel treatment for lung transplantation-related complications, enhance the overall prognosis and improve the quality of life of lung transplant recipients
As a novel solid organ transplantation, uterus transplantation has become an important approach for women with uterine infertility to obtain biological offspring. Multiple technological challenges exist in uterus transplantation, such as acquisition of vascular pedicle, organ perfusion and vascular suture, etc. However, with the development and application of uterus transplantation in animal model and transplantation in human cadavers, a lot of problems have become new hot topics of discussion, such as the selection of uterus transplantation donors and recipients, selection of uterine vessels, prevention and treatment of complications after uterus transplantation, evaluation of graft vitality, timing of pregnancy and delivery, timing of hysterectomy, mental health of donors and recipients and offspring health, etc. According to current data and outcomes of human uterus transplantation worldwide, these hot topics were reviewed in this article, aiming to provide reference for promoting the development and progress of human uterus transplantation research in China.
Vitamin D3 is a kind of vitamin that plays important roles in maintaining the normal physiological function of the human body, and its metabolites and analogues exhibit strong anti-inflammatory activity. Vitamin D3 could be activated and converted into 1α, 25-dihydroxyvitamin D3, a kind of steroid hormone, in the human body, which participates in the regulation of cellular metabolism by activating vitamin D receptor (a kind of transcription factor), thus exerting immunomodulatory effects. This is essential for maintaining the physiological health of the body. Currently, there is a growing number of studies that suggest important roles for 1α, 25-dihydroxyvitamin D3 in organ transplantation immunomodulation and tolerance. Therefore, we reviewed the overview and physiological effects of 1α, 25-dihydroxyvitamin D3, the immunomodulatory effects of vitamin D3 and the application of vitamin D3 in clinical organ transplantation, and summarized the value of applying vitamin D3 in inducing immune tolerance in transplantation, with the aim of providing a reference for promoting the application of vitamin D3 in transplantation immunity.
