Pancreas numbers are down: Pancreas transplantation is the only long-term treatment for diabetes which restores glucose homeostasis, without the risks of hypoglycemia.(1-3) Further, receiving a simultaneous pancreas kidney (SPK) transplant improves life expectancy over kidney transplantation alone.(4,5) Despite this, the total number of pancreas transplants in the United States has decreased since 2006. Experts in the field recently reported that, while this drop in volume is multifactorial, the lack of a steady referral source is partly to blame...

Kidney paired donation (KPD) is an important tool to facilitate living donor kidney transplantation (LDKT). Concerns remain over prolonged cold ischemia times (CIT) associated with shipping kidneys long distances through KPD. We examined the association between CIT and delayed graft function (DGF), allograft survival, and patient survival for 1,267 shipped and 205 non-shipped/internal KPD LDKTs facilitated by the National Kidney Registry in the United States from 2008-2015, compared to 4,800 unrelated, non-shipped, non-KPD LDKTs...

We read with interest the letter from Dr. Del Bello and colleagues regarding our recent case report of successful combined liver/kidney transplantation in a patient with primary hyperoxaluria type 2 (PH2) that resulted in normalization of urine and plasma oxalate levels. They describe a patient with PH2 who, unfortunately, developed renal allograft failure 6 months after a kidney alone transplant (1). The reasons for renal allograft failure in their patient are not entirely clear. This article is protected by copyright...

Simultaneous pancreas/kidney (SPK) transplantation is an important treatment option for patients with type 1 diabetes (T1D) and end stage renal disease (ESRD). Due to complications, in up to 10% of cases allograft pancreatectomy is necessary shortly after transplantation. Usually the donor pancreas is discarded. Here we report on a novel procedure to rescue endocrine tissue after allograft pancreatectomy. A 39-year-old woman with T1D and ESRD who had received an SPK transplantation required emergency allograft pancreatectomy due to bleeding at the vascular anastomosis...

Thymic function progressively decreases with age but may be boosted in certain circumstances. We questioned whether heart transplantation was such a situation and whether the thymic function was related to the onset of rejection. Twenty-eight antithymocyte globulin-treated heart transplant recipients were included. Patients diagnosed for an antibody-mediated rejection on endomyocardial biopsy had higher proportion of circulating recent thymic emigrant CD4+ T cells and T cell receptor excision circle levels than other transplanted subjects...

Beyond the first posttransplant year, 3% of kidney transplants fail annually. In a prospective, multicenter cohort study, we tested the relative impact of early versus late events on risk of long-term death-censored graft failure (DCGF). In grafts surviving at least 90 days, early events (acute rejection [AR] and delayed graft function [DGF] before day 90) were recorded; serum creatinine (Cr) at day 90 was defined as baseline. Thereafter, a 25% rise in serum Cr or new onset proteinuria triggered graft biopsy (index biopsy, IBx), allowing comparison of risk of DCGF associated with early events (AR, DGF, baseline serum Cr >2...

Using a retrospective cohort that was part of a donor intervention trial published in 2009 (1) , Schnuelle et al report in this issue that spontaneous hypothermia in deceased organ donors resulted in decreased recipient renal delayed graft function(2) . Allograft survival was not statistically significantly different during long-term follow up. While spontaneous hypothermia is likely a distinct physiologic process compared to targeted mild hypothermia, as in our previously reported randomized controlled trial(3) , the findings of the current retrospective study further confirm our impression that therapeutic mild hypothermia and deceased organ donor intervention research, in general, hold tremendous potential for addressing the ongoing shortage of organs available for transplantation...

Graft survival after small bowel transplantation remains impaired due to acute cellular rejection (ACR), the leading cause of graft loss. Although it was shown that the number of enteroendocrine progenitor cells in intestinal crypts was reduced during mild ACR, no results of Paneth and intestinal stem cells localized at the crypt bottom have been shown so far. Therefore, we wanted to elucidate integrity and functionality of the Paneth and stem cells during different degrees of ACR, and to assess whether these cells are the primary targets of the rejection process...

Evidence is currently lacking regarding the outcomes of kidneys undergoing Hypothermic Machine Perfusion (HMP) in the UK. Using the National Health Service Blood and Transplant database, the authors compared outcomes for recipients of single organ Donation after Circulatory Death (DCD) kidneys preserved with HMP to those using only static cold storage (SCS). Between 2007 and 2015, HMP was used in 19.1% (864/4,529) of kidneys. Rates of delayed graft function (DGF) were significantly lower in organs preserved with HMP than for SCS (34...

Changes in heart transplant (HT) donor and recipient demographics may influence the incidence of primary graft dysfunction (PGD). We conducted a retrospective study to evaluate PGD incidence, trends, and associated risk factors by analyzing consecutive adult patients who underwent HT between January 2009 and December 2014 at our institution. Patients were categorized as having PGD using the International Society of Heart and Lung Transplantation defined criteria. Variables, including clinical and demographic characteristics of donors and recipients, were selected to assess their independent association with PGD...

Liver ischemia-reperfusion injury (IRI) represents a major risk factor of early graft dysfunction and a key obstacle to expanding the donor pool in orthotopic liver transplantation (OLT). Although graft autophagy is essential for resistance against hepatic IRI, its significance in clinical OLT remains unknown. Despite recent data identifying heme oxygenase-1 (HO-1) as a putative autophagy inducer, its role in OLT and interactions with Sirtuin-1 (SIRT1), a key autophagy regulator, have not been studied. We aimed to examine HO-1 mediated autophagy induction in human OLT and in a murine OLT model with extended (20h) cold storage, as well as to analyze the requirement for SIRT1 in autophagy regulation by HO-1...

Kidney transplant patients treated with belatacept without depletional induction experience higher rates of acute rejection compared to patients treated with conventional immunosuppression. Costimulation blockade-resistant rejection (CoBRR) is associated with terminally differentiated T cells. Alemtuzumab induction and belatacept/sirolimus immunotherapy effectively prevents CoBRR. We hypothesized that cells in late phases of differentiation would be selectively less capable of repopulating post-depletion than more naïve phenotypes, providing a potential mechanism by which lymphocyte depletion and repopulation could reduce the risk of CoBRR...

Ischemia and reperfusion injury (IRI) is an inevitable event in conventional organ transplant procedure and is associated with significant mortality and morbidity post-transplantation. We hypothesize that IRI is avoidable if the blood supply for the organ is not stopped, thus resulting in optimal transplant outcomes. Here we described the first case of a novel procedure called ischemia-free organ transplantation (IFOT) for patients with end-stage liver disease. The liver graft with severe macrovesicular steatosis was donated from a 25-year-old man...

Erythropoieitic protoporphyria (EPP) is a rare inherited disorder of the heme biosynthesis pathway resulting in the accumulation of protoporphyrins in the blood, erythrocytes, and other tissues. Because of a gene mutation in the FECH gene, ferrochelatase, the enzyme involved in the final step of heme synthesis, is deficient in these patients. While the major symptom of this disorder is photosensitivity, rarely, it can cause progressive liver disease requiring liver transplantation (LT). However, LT is not curative and only bone marrow transplantation (BMT) can correct the underlying enzymatic defect...

Patients with End Stage Renal Disease (ESRD) use the emergency department (ED) at a 6-fold higher rate than U.S. adults. No national studies have described ED utilization rates among kidney transplant (KTx) recipients, and the factors associated with higher ED utilization. We examined a cohort of 132,725 adult KTx recipients in the United States Renal Data System (2005-2013). ED visits, hospitalization, and outpatient nephrology visits were obtained from Medicare claims databases. Nearly half (46.1%) of KTx recipients had at least one ED visit (1...

The Model for End-stage Liver Disease (MELD) score predicts higher transplant healthcare utilization and costs; however, the independent contribution of functional status towards costs is understudied. The study objective was to evaluate the association between functional status, as measured by Karnofsky Performance Status (KPS), and liver transplant (LT) costs in the first post-transplant year. In a cohort of 598 LT recipients from 7/1/2009-11/30/2014, multivariable models assessed associations between KPS and outcomes...

Scedosporium is an important pathogen in cystic fibrosis (CF) and post-transplant, but it rarely causes invasive infection. Treatment remains challenging, particularly due to the inherent resistance to multiple antifungal agents. We present three complicated invasive tracheobronchial and lung Scedosporium apiospermum infections following lung transplant. In two of three cases, the infection was clinically and radiologically cured with frequent cleansing bronchoscopies, combining triazole with terbinafine therapy and nebulized posaconazole...

Transplant candidates who accept a kidney labeled increased risk for disease transmission (IRD) accept a low risk of window period infection, yet those who decline must wait for another offer that might harbor other risks or never even come. To characterize survival benefit of accepting IRD kidneys, we used 2010-2014 SRTR data to identify 104,998 adult transplant candidates who were offered IRD kidneys that were eventually accepted by someone; the median (IQR) KDPI of these kidneys was 30 (16-49). We followed patients from the offer decision until death or end-of-study...

The prevalence of prostate carcinoma in kidney transplant male recipients approach 1.1% (1). Despite increasing reports of RRP performed for ageing kidney transplant recipients, there are no publications addressing post-operative complications including transplant ureteric injuries(2-3). These complications are potentially devastating and difficult to salvage, as illustrated by the following report of an opportunistic utilisation of BFV to manage complete ureteric obstruction of the transplant kidney after a RRP...

Zika virus (ZIKV) cases have been detected across the United States (US) and locally acquired cases have been reported in Florida. Currently, there are no ZIKV screening guidelines and no data on the incidence among organ donors in the US. This retrospective study was conducted at Jackson Memorial-Miami Transplant Institute. Positive ZIKV tests in local deceased organ donors were investigated from 6/2016 to 1/2017. We evaluated demographics and risk factors for ZIKV infection among organ donors and transplant outcomes among recipients of donors with positive ZIKV testing...
