Thongprayoon C, Garcia Valencia OA, Miao J, Craici IM, Mao SA, Mao MA, Tangpanithandee S, Pham JH, Leeaphorn N and Cheungpasitporn W
Kidney retransplantation offers a valuable treatment option for patients who experience graft failure after their initial transplant. There is an increasing number of patients undergoing multiple retransplants. However, the impact of multiple kidney retransplants on post-transplant outcomes remains unclear. This study aimed to assess the association between the number of kidney retransplants and post-transplant outcomes in kidney retransplant recipients.

Yamamoto H, Isono K, Honda M, Sugawara Y, Inomata Y and Hibi T
Liver retransplantation (reLT), which is the only treatment for liver graft failure, remains challenging not only because of its technical nature but also because it is performed in high-risk patients.
Novel Approach to Vascular Thymic Tissue Transplantation in Humans: A Case Report
Tintinago-Londoño LF, Jaramillo-Echeverry FJ, Guzmán TM, Bravo-Ocaña JC, Silva-Pérez NM and Abella-Calle J
Vascular thymus transplantation has been explored in animal models but remains untested in humans. Current approaches to congenital athymia involve avascular transplantation of allogeneic thymic tissue, which may delay immune recovery. Building on animal studies, we propose revascularization of thymic tissue in a human model. This case report details about the revascularization of neonatal thymic tissue in an elderly woman with terminal cancer, evaluating revascularization efficacy, rejection risks, and procedural safety over a 3-week period.
Quality of Life in Pediatric CKD Patients on Dialysis vs Renal Transplantation: A Comparative Study of the Perspectives of Parents and Children
Alaskar M, AlQattan F, Al-Shami S, Hamed A and Alshami A
Chronic kidney disease (CKD) is a burden on children and their caregivers, especially in advanced stages requiring different renal replacement modalities (peritoneal/hemodialysis and renal transplant). The aim of the study is to measure the health-related quality of life (HRQOL) of children and their caregivers for each renal replacement modality, specifically dialysis and transplant.
Calcitriol Treated Mesenchymal Stem Cells Modulated Immune Response in Collagen-Induced Rheumatoid Arthritis in BALB/c Mice
Rafati A, Ramezani R, Esmaeili Gouvarchin Ghaleh H, Bahrami S, Alvanegh AG and Masoudi MR
Rheumatoid arthritis (RA) is a chronic inflammatory disease that primarily involves synovial joints. During the past decade, disease-modifying antirheumatic drugs and biologic agents have been introduced for the treatment of RA. However, they have limitations, including incomplete treatment response, adverse effects requiring drug withdrawal, fall off in efficacy over time, high cost of biologic agents, and refractory cases. Consequently, there is a need to establish safe and effective advanced therapeutic modalities for RA to overcome the shortcomings of current treatments.

Acquired Diaphragmatic Hernia and Intestinal Obstruction in a Child with Methylmalonic Acidemia Following Pediatric Liver Transplantation
Ye H, Chen X, Lin Y, Hu P, Wen L, Yang Y, Liu N and Dang R
An acquired diaphragmatic hernia (ADH) is an uncommon event following pediatric liver transplantation. Pediatric liver transplantation proves effective in prolonging survival and improving quality of life for children with methylmalonic acidemia. Remarkably, there have been no previous reports documenting the occurrence of post-liver transplant ADH in patients diagnosed with methylmalonic acidemia.
Nonlinear Relationship Between Body Mass Index and Liver Transplant Outcomes: A Dose-Response Meta-Analysis
Liang C, Yin S, Song T and Lin T
Weight management was recommended to have more access to transplantation and improve transplant outcomes after liver transplantation (LT). However, the dose-response relationship between body mass index (BMI) and transplant outcomes has not been clearly defined.
Comparison of Clinical Outcomes Between Two Types of Dipeptidyl Peptidase-4 Inhibitors in Posttransplant Diabetes Mellitus in Kidney Transplantation Recipients: A Nationwide Population-Based Cohort Study in Korea
Lee KY, Song GY, Seo MJ, Kim SH, Kang DR, Park K, Kim JT, Park SW and Lee JY
Dipeptidyl peptidase-4 inhibitors (DPP-4i) are antidiabetic drugs known for their minimal side effects and limited drug interaction witih immunosuppressants, making them suitable for patients with diabetes and kidney transplant recipients. However, there is limited real-world information regarding the use of DPP-4 inhibitors in patients with post transplant diabetes mellitus (PTDM).
Perioperative Variation of Plasma Copeptin and Its Association With Vasopressor Need During Liver Transplantation
Gunt C and Çekmen N
Vasopressor usage during liver transplant is related to decreased hepatic flow, graft failure, and mortality. We measured plasma Copeptin levels in liver transplant patients based on vasopressor requirements. We hypothesize that preoperative plasma copeptin measurement helps predict the vasopressor infusion requirement during liver transplantation in preoperative evaluation.
Extracorporeal Photopheresis, a Therapeutic Alternative for T cell-mediated Rejection in Renal Transplantation
de Lara Gil M, Gil Muñoz M, de Lara Gil E, Blanquer M, Llorente Viñas S, Morales Caravaca F, Saura Luján I and Cabezuelo Romero JB
T-cell mediated rejection (TCMR) in renal transplantation, although reduced by better immunosuppressants, still impacts graft survival. TCMR responds to methylprednisolone (MPL) in 60% to 70% of cases, with polyclonal anti-T-lymphocyte antibodies (ATGs) used for severe or corticoresistant cases. When ATG is contraindicated, extracorporeal photopheresis (ECP) may be an alternative. ECP involves treating immune cells with 8-methoxypsoralen and ultraviolet-A radiation before reinjection, with effect in various T-cell-mediated and autoimmune diseases. This study included two renal transplant recipients with severe TCMR. Patient 1's creatinine levels were 1.4 mg/dL baseline, 2.2 mg/dL at TCMR diagnosis, and 1.9 mg/dL at ECP initiation. Patient 2's levels were 1 mg/dL baseline, 1.8 mg/dL at diagnosis, and 1.42 mg/dL at ECP initiation. The THERAKOS CELLEX system was used for patient 1, and the OPTIA system was used for patient 2, both with methoxsalen. ECP is highlighted as a viable option for TCMR in renal transplantation when conventional treatments are unsuitable.
Evaluation of Liver Volume Estimation Methods in Living Donor Liver Transplant: CT Volumetry vs MeVis, With Comparison of Open and Laparoscopic Surgery
Tan EK, Zheng V, Tuieng SY, Low ASC, Chai STS, Phang YX, Koh YX, Chung AYF, Cheow PC, Jeyaraj PR and Goh BKP
Accurately assessing graft volume is crucial for donor and recipient safety in living donor liver transplantation. This can be performed using manual computed tomography volumetry (CTvol) or semiautomated methods (MeVis). We aimed to compare CTvol and MeVis in estimating the actual graft weight during LDLT, and analyse any differences in weight between laparoscopic and open donor hepatectomy.

Quilis A, Gavela E, Kánter J, Castro-Alonso C, Calatayud E, Vivó E, Parra M, Gandia P and Sancho A
The potential anti-proteinuric effect of sodium-glucose cotransporter-2 inhibitors (SGLT2i) is of special interest in kidney transplantation. Its benefits have been demonstrated in diabetic kidney transplant recipients (KTRs). We analyzed the efficacy and safety of SGLT2i in non-diabetic KTRs collecting clinical and analytical data at baseline and 6 months after the introduction of the drug.

Budhiraja P, Butterfield R, Hommos M, Heilman RL, Cheungpasitporn W, Alajous S, Me HM, Chakkera HA, Corey RL, Abu Jawdeh BG and Khamash HA
We assessed the accuracy of different GFR estimating equations in kidney transplant recipients across diverse racial backgrounds, addressing the previously identified validation gap in multiethnic populations predominantly studied in White cohorts.
Effect of Pre-Transplant Renal Anticoagulation and Antiplatelet Therapy on Post-Transplant Outcomes: A Retrospective Single-Center Study
Fuentes-Fernández C, Maldonado-Martin M, González Garcia E, León-Machado L, Jiménez C and López-Oliva MO
The management of anticoagulation and antiplatelet therapy in stage V chronic kidney disease (CKD) patients undergoing renal transplantation remains controversial. Some centers advocate for the use of reversal agents or procoagulants preoperatively, while others suggest that transplantation can proceed safely without halting these treatments. This study aims to evaluate the incidence of hemorrhagic and thrombotic complications in the first 72 hours post-transplant in patients receiving anticoagulant or antiplatelet therapy compared to a control group without such treatments. We conducted a retrospective cohort study involving 168 kidney transplant patients at our center from June 2018 to February 2022, with a follow-up period of 6 months post-transplant. Among these, 147 patients were included: 8.2% were anticoagulated, 16.3% were on antiplatelet therapy, and 75.5% received neither treatment. Patients on anticoagulants or antiplatelets were generally older, had a higher prevalence of cardiovascular history, and experienced longer dialysis times. Anticoagulated patients exhibited longer cold ischemia times and increased rates of hyperimmunization, alongside prolonged hospital stays. The overall incidence of hemorrhagic complications in the first 3 days post-transplant was low across all groups: 9% in the control group, 8.3% in anticoagulated patients, and 8.4% in antiplatelet-treated patients, with no significant differences. Blood transfusion rates were 75% for anticoagulated patients, 62.5% for antiplatelet patients, and 51.7% for controls (P = .214). Renal function at 6 months was similar across groups (P = .477), though acute rejection rates were higher in anticoagulated patients (16.6% vs. 4.2% vs. 2.7%; P = .067). No significant differences were found in hemorrhagic and thrombotic complications among the groups.
Priority Should be Given to Centers that Split En Bloc Pediatric Kidneys to Maximize Transplantation: A Single Center Experience
Barbash D, Steinberger M, Torabi J, Yaffe H, Ajaimy M, Akalin E, Liriano LE, Azzi Y, Jain S, Pynadath C, Muhdi N, Le M and Graham JA
The foundation for OPTN policy 8.5.B that allows for en bloc kidney utilization from pediatric donors under <18 kg is unclear. Naturally, kidneys recovered from these donors can be split and transplanted into 2 adult recipients as opposed to only 1 (OPTN policy 8.5.C). Our center universally splits all pediatric donor kidneys. We showed that early eGFR is lower in recipients that receive a kidney from a donor <18 kg (3-month eGFR; 36.3 vs 49.7 mL/min/1.73 m, P = .01), but quickly rebounds with no significant differences thereafter. As such, efforts should be made to revisit the practice of en bloc kidney transplantation from small pediatric donors. Given similar complication rates and outcomes seen at our center between the 2 groups, "splitting first" should be the policy to ensure maximalization of transplant recipients.
