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.
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.
Eye organoid refers to a structure that possesses resembling cell types and functions to intraocular tissues, which is induced by stem cells in vitro. Transplanting it into the body for eye repair and regeneration is one of the key research directions in regenerative medicine, which also provides a novel direction and strategy for the treatment of major blinding diseases. As a carrier of biological tissue or cell growth, tissue engineering scaffold could support in vivo transplantation of eye organoids and promote their maturation. Organic combination of eye organoids and tissue engineering is a critical approach to realize in vivo integration of eye organoids and reconstruct corresponding structures and functions. In this review, the latest research status of eye organoids and in vivo transplantation were summarized, and relevant studies of tissue engineering scaffold-assisted eye organoid transplantation were highlighted, aiming to provide ideas and reference for subsequent inter-disciplinary research of eye organoids and tissue engineering.
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.
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.
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.
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.
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.
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.
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.
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.
