BACKGROUND Precise evaluation of a living donor's renal function is necessary to ensure adequate residual kidney function after donor nephrectomy. Our aim was to evaluate the feasibility of estimating glomerular filtration rate (GFR) using serum cystatin-C prior to kidney transplantation. MATERIAL AND METHODS Using the equations of the Japanese Society of Nephrology, we calculated the GFR using serum creatinine (eGFRcre) and cystatin C levels (eGFRcys) for 83 living kidney donors evaluated between March 2010 and March 2016...

BACKGROUND & OBJECTIVES: Antibodies specific to donor human leucocyte antigen (HLA) play a critical role in graft rejection and graft loss. In recent years, techniques for their detection have evolved significantly providing an ever-increasing degree of sensitivity and specificity, from the conventional cell-based assays to the advanced solid-phase system based on the Luminex platform. Consensus is still evolving on the routine employment of all these methods, either stand alone or in combination...

BACKGROUND: Kidney donor outcomes are gaining attention, particularly as donor eligibility criteria continue to expand. Kidney size, a useful predictor of recipient kidney function, also likely correlates with donor outcomes. Although donor evaluation includes donor kidney size measurements, the association between kidney size and outcomes are poorly defined. METHODS: We examined the relationship between kidney size (body surface area-adjusted total volume, cortical volume and length) and renal outcomes (post-operative recovery and longer-term kidney function) among 85 kidney donors using general linear models and time-to-chronic kidney disease data...

ABO-incompatible (ABO-i) living-donor liver transplantation (LDLT) is performed if an ABO-compatible graft cannot be obtained. However, a perfect desensitization protocol has not been established worldwide, especially for simultaneous ABO-i LDLT and splenectomy. We herein report two cases of ABO-i LDLT. To the best of our knowledge, this is the first case report of ABO-i LDLT in an adult patient in China. Splenectomy and T-cell-targeted immunosuppression (basiliximab) was used to overcome the blood group barrier in these recipients...

Over the last several years, liver transplantation has evolved to become a widely used treatment for hepatocellular carcinoma (HCC). The criteria used were developed in order to have acceptable outcomes for transplant with survival similar to other indications for transplant. These criteria are discussed in detail along with alternate options, including surgical resection and downstaging of HCC in cirrhotics. Technical considerations of liver transplantation must be considered, and living donor liver transplant is a possibility for treatment...

OBJECTIVE: The aim of this study was to evaluate the utility of the P4 stump stenting approach for treating portal vein (PV) complications in pediatric living donor liver transplantation (LDLT). BACKGROUND: PV complications cause significant morbidity and mortality in pediatric LDLT. Biliary atresia in the backdrop of pathological PV hypoplasia and sclerosis heightens the complexity of PV reconstruction. The authors developed a novel approach for intraoperative PV stenting via the graft segment 4 PV stump (P4 stump) to address this challenge...

OBJECTIVE: To evaluate the relationship between donor sex and hepatocellular carcinoma (HCC) recurrence after living donor liver transplantation. BACKGROUND: HCC shows a male predominance in incidence and recurrence after tumor resection due to sex differences in hepatic sex hormone receptors. There have been no studies evaluating the importance of donor sex on post-transplant HCC recurrence. METHODS: Of 384 recipients of livers, from living donors, for HCC: 104/120 who received grafts from female donors were matched with 246/264 who received grafts from male donors using propensity score matching, with an unfixed matching ratio based on factors like tumor biology...

Allogeneic hematopoietic cell transplantation (HCT) is curative in patients with β-thalassemia major. However, the majority of reports on HCT outcomes lack long-term follow-up data with the exception of single center reports. An international multicenter retrospective data collection and analysis was conducted in 176 β-Thalassemia patients who were 1 year or beyond after first HCT to evaluate follow up methods and outcomes at 7 centers- Median age at HCT was 5.5 years (range, 0.6- 18.5) and median follow-up was 7 years (range, 1-20)...

Growing evidence suggests a relationship between antibody-mediated rejection (AMR) and early graft failure due to a previously unknown etiology in liver transplantation (LTx). We herein report a three-year-old boy who developed rapid graft failure due to de novo donor-specific antibody (DSA)-driven AMR a week after living donor LTx, requiring a second transplant on the 10th day after the first LTx. The pathology of the first graft showed massive necrosis in zone 3 along with positive C4d and inflammatory cell infiltrates in portal areas...

REVIEW
Floris J M Roos, Jan-Werner Poley, Wojciech G Polak, Herold J Metselaar
Biliary complications are considered to be the Achilles' heel of liver transplantation. The most common complications are leaks and bile duct strictures. Strictures can arise at the level of the anastomosis (anastomotic strictures; AS) or at other locations in the biliary tree (non-anastomotic strictures; NAS). Endoscopic treatment via endoscopic retrograde cholangiopancreatography (ERCP) is considered to be the preferred therapy for these complications. This review will focus on the diagnostic modalities, new insights in etiology of biliary complications and outcomes after different endoscopic therapies, in both deceased donor transplantation and living-donor liver transplantations...

Long-lived, donor-reactive memory B cells (Bmem) can produce alloantibodies that mediate transplant injury. Autophagy, an intrinsic mechanism of cell organelle/component recycling, is required for Bmem survival in infectious and model antigen systems but whether autophagy impacts alloreactive Bmem is unknown. We studied mice with an inducible yellow fluorescent protein (YFP) reporter expressed under the Activation-Induced Cytidine Deaminase (AID) promoter active in B cells undergoing germinal center reactions...

OBJECTIVES: Organs from brain-dead donors are the main source of allografts for transplant. Comparisons between living-donor and brain-dead donor kidneys show that the latter are more likely to demonstrate delayed graft function and lower long-term survival. This study aimed to assess the effects of various clinical and biochemical factors of donors on early- and long-term renal function after transplant. MATERIALS AND METHODS: We analyzed data from kidney recipients treated between 2006 and 2008 who received organs from brain-dead donors...

BACKGROUND: Organ dysfunction is common after neurologic determination of death (NDD) but before organ collection. Reliable markers for graft success following transplant of these organs would be useful. We sought to determine the relationship between the donor after neurologic determination of death (DNDD) pathophysiology and successful organ donation. METHODS: Donor information was obtained through the local organ procurement organization. Donor demographics and clinical data points for cardiovascular, renal, respiratory, hepatic, hematological and neuroendocrine systems were reviewed 12 h before and 12 h after neurologic determination of death was declared...
