The induction of donor-specific transplant tolerance has always been a central problem for small bowel transplantation (SBT), which is thought to be the best therapy for end-stage bowel failure. With the development of new tolerance-inducing strategies, mixed chimerism induced by co-stimulation blockade has become most potent for tolerance of allografts, such as skin, kidney, and heart. However, a lack of clinically available co-stimulation blockers has hindered efficient application in humans. Furthermore, unlike those for other types of solid organ transplantation, strategies to induce robust mixed chimerism for intestinal allografts have not been fully developed...

Since 2001, the team of the organ and tissue procurement unit of Nancy general hospital has practised the minimally invasive laparoscopic organ removal procedure through robot-assisted surgery. Here the team shares its expertise in the area of kidney removal from a living donor. Perfectly synchronised with the procedure of the team in charge of the transplant, the surgical stages are carried out in sequence ensuring optimal safety for the donor and recipient.

For people with end-stage kidney disease, a transplant is the promise of a future without dialysis. Living donor kidney transplantation comprises many specificities and is distinct from cadaveric donor transplantation. Some psychological aspects explain these specificities. They may be subconscious and difficult to access, but it is essential to decipher them in order to adapt the support provided to these people.

The ethical debate surrounding transplant practices questions our societies. International recommendations set out numerous precautions which must be taken to ensure that donors act with their free will. While in most countries, including France, organ donation is a voluntary and non-commercial act, a black market exists in the world resulting in the trafficking of organs and tragic transplant tourism.

Living donor kidney transplantation has been increasing since 2008. Living donors represent a significant potential for organ transplants, in a context where the needs outstrip the availability of organs from deceased donors. However, patients are still poorly informed regarding the conditions in which these transplants are possible.

BACKGROUND: Simple renal cysts may be an early marker of renal disease. We investigated whether simple cysts in donor kidney are associated with the decline of allograft function in living donor kidney transplantation. METHODS: We retrospectively reviewed records of donors and recipients from 716 living donor kidney transplants performed between April 2007 and April 2015 in our hospital. Ninety-one donors with renal cysts and 64 recipients with cysts in donor kidney were noted...

BACKGROUND: Natural killer (NK) cells localize in the microcirculation in antibody-mediated rejection (ABMR) and have been postulated to be activated by donor-specific anti-HLA antibodies triggering their CD16a Fc receptors. However, direct evidence for NK cell CD16a triggering in ABMR is lacking. We hypothesized that CD16a-inducible NK cell-selective transcripts would be expressed in human ABMR biopsies and would offer evidence for CD16a triggering. METHODS: We stimulated human NK cells through CD16a in vitro, characterized CD16a-inducible transcripts, and studied their expression in human kidney transplant biopsies with ABMR and in an extended human cell panel to determine their selectivity...

Previous studies on patient and allograft outcomes of obese kidney transplant recipients (KTRs) remain controversial. To what extent obesity-related comorbidities contribute to adverse outcomes, however, hasn't been addressed. We studied all KTRs from 2005 to 2012. 29 (4%), 317 (48%), 217 (33%), 76 (12%), and 21 KTRs (4%) were identified as underweight, normal-weight, overweight, obese, and morbid obese, respectively. 33 of 97 obese KTRs (34%) had pre-existent diabetes. Samples were collected before transplantation and at +1, +2, +3months posttransplantation...

A 40-year-old male with a long-standing history of type 1 diabetes with end-stage renal failure underwent combined kidney-pancreas (KP) transplant from a standard criteria donor. Post-operative course was uncomplicated with good primary function of both transplant grafts. Induction was with thymoglobulin and maintenance immunosuppression was with tacrolimus, mycophenolate mofetil and prednisolone. Nine weeks post-transplant, the patient developed dysfunction of both grafts. Panel reactive antibody testing revealed that the patient had developed a de novo donor-specific antibody and considering an antibody-mediated rejection the patient was treated with intravenous pulse methyl prednisone 500 mg ×3 doses, IV immunoglobulin 2 mg/kg in two divided doses, and ATG 7 mg/kg (total dose of 700 mg)...

BACKGROUND: Kidney transplantation is the definite surgical treatment for end-stage renal disease. Shortage of organs and the increasing number of patients with end-stage renal disease has led to an expansion of the selection criteria promoting the use of organs from marginal donors. Use of kidneys with renal artery aneurysm (RAA) is one such example. Description of the case: We report a case of living-related kidney transplantation from a 46-year-old female donor with unilateral RAA to her 68-year-old father...

In the past decades liver transplantation (LT) has become the treatment of choice for patients with end stage liver disease (ESLD). The chronic shortage of cadaveric organs for transplantation led to the utilization of a greater number of marginal donors such as older donors or donors after circulatory death (DCD). The improved survival of transplanted patients has increased the frequency of long-term complications, in particular chronic kidney disease (CKD). Acute kidney injury (AKI) post-LT has been recently recognized as an important risk factor for the occurrence of de novo CKD in the long-term outcome...

BACKGROUND Graft thrombosis is the main cause of early graft loss after transplantation. In Japan, pancreases available for transplantation are frequently from marginal donors due to diverse backgrounds in the population. However, marginal tissues increase the risk of early thrombosis in the graft. CASE REPORT Here, we describe a 41-year-old woman with type 1 diabetes mellitus who underwent a simultaneous pancreas-kidney transplantation. The pancreas was retrieved from a 34-year-old man who had experienced severe hemodynamic instability...

BACKGROUND AND OBJECTIVES: Historically, length of pretransplant dialysis was associated with premature graft loss and mortality after kidney transplantation, but with recent advancements in RRT it is unclear whether this negative association still exists. DESIGN, SETTING, PARTICIPANTS, &MEASUREMENTS: This is a retrospective cohort study evaluating 6979 first kidney allograft recipients from the Austrian Registry transplanted between 1990 and 2013. Duration of pretransplant dialysis treatment was used as categoric predictor classified by tertiles of the distribution of time on dialysis...

BACKGROUND: The Luminex(®) single antigen bead assay (SAB) is the method of choice for monitoring the treatment for antibody-mediated rejection (AMR). A ⩾50% reduction of the dominant donor-specific antibody (IgG-DSA) mean fluorescence intensity (MFI) has been associated with improved kidney allograft survival, and C1q-fixing DSA activity is associated with poor outcomes in patients with AMR. We aimed to investigate if C1q-DSA can be used as a reliable predictor of response to therapy and allograft survival in patients with biopsy-proven AMR...

BACKGROUND: The survival rates of renal transplant children are indeed on the rise, but it is still important to ensure that there is optimal renal function in these children in all their future growing years. The number of functioning nephrons and the graft ability to adapt to an increasing demand during body growth seem to be the most important factors for long-term allograft function. This study examined the long-term change in the glomerular filtration rate in a pediatric kidney transplant cohort and the importance of the recipient and donor ages in predicting transplant outcome...

BACKGROUND: The role of DNA methylation in the regulation of the anti-donor-directed immune response after organ transplantation is unknown. Here, we studied the methylation of two mediators of the immune response: the pro-inflammatory cytokine interferon γ (IFNγ) and the inhibitory receptor programmed death 1 (PD1) in naïve and memory CD8+ T cell subsets in kidney transplant recipients receiving immunosuppressive medication. Both recipients experiencing an episode of acute allograft rejection (rejectors) as well as recipients without rejection (non-rejectors) were included...

The new Kidney Allocation System (KAS) provides additional allocation points for candidates with broad HLA sensitization in an effort to increase transplant rates for this underserved population. Following the implementation of KAS, our center lowered the HLA antibody threshold for listing unacceptable antigens from a cytotoxicity crossmatch level to a flow cytometric crossmatch level increasing Calculated Panel Reactive Antibody (CPRA) values and allocation points, yet restricting acceptable donor HLA phenotypes...

BACKGROUND: Donor-specific antibody (DSA) is a widely-used biomarker for antibody-mediated rejection (ABMR) but correctly indicates only 30-40% of patients with ABMR. Additional biomarkers of ABMR in kidney transplant recipients are needed. METHODS: All 68 kidney transplanted-recipients enrolled in this study were negative for graft rejection as determined by surveillance-biopsy ELISA at day 7 post-transplantation. Allograft biopsy was then performed at 6 months post-transplantation for subclinical-ABMR detection...
