The Impact of Early Brain-Dead Donor Detection in the Emergency Department on the Organ Donation Process in Iran.

We aimed to assess the impact of hospital characteristics on the outcomes of detected possible brain-dead donors, in our organ procurement network in Iran. Data was collected through twice-daily calls with 57 hospitals' intensive care units and emergency departments over 1 year. The donation team got involved when there was suspicion of brain death before the hospital officially declared it. The data was categorized by hospital size, presence of neurosurgery/trauma departments, ownership, and referral site. Out of 813 possible donors, 315 were declared brain dead, and 203 were eligible for donation. After conducting family interviews (consent rate: 62.2%), 102 eligible donors became actual donors (conversion rate: 50.2%). While hospital ownership and the presence of trauma/neurosurgery care did not affect donation, early referral from the emergency department had a positive effect. Therefore, we strongly recommend prioritizing possible donor identification in emergency rooms and involving the organ donation team as early as possible. The use of twice-daily calls for donor identification likely contributed to the consistency in donation rates across hospitals, as this approach involves the donation team earlier and mitigates the impact of hospital characteristics. Early detection of possible donors from the emergency department is crucial in improving donation rates.

Effect of revised organ transplant law in Japan on lung transplantation.

PURPOSE: To investigate how revision of the organ transplant law in Japan affected lung transplantation in this country. METHODS: Lung transplant candidates registered between January, 2000 and December, 2009 were designated as the pre-revision group (n = 396) and those registered between January, 2011 and December, 2020, as the post-revision group (n = 1326). Both groups were analyzed retrospectively using data collected by the Japanese Society of Lung and Heart-Lung Transplantation. RESULTS: The number of patients who underwent brain-dead donor lung transplantation (BDLT) increased significantly after the law amendment (32.2 vs. 13.8%, p < 0.01). The median waiting time for BDLT was significantly reduced (708 days vs. 1163 days, p < 0.01) and the mortality rate while waiting for BDLT improved significantly after the law amendment (33.1 vs. 42.6%, p < 0.01). In the post-revision group, 18 pediatric patients underwent BDLT. The 5-year survival rates after BDLT were comparable between the groups (73.5% in the pre-revision group vs. 73.2% in the post-revision group, p = 0.32). CONCLUSIONS: The organ transplant law revision shortened the waiting time for BDLT significantly and decreased the mortality rate while waiting for BDLT. The posttransplant outcomes in Japan remained favorable throughout the study period.

Association between artificial nutrition in brain dead donors and early allograft function in liver transplant recipients: an observational study.

BACKGROUND: The role of nutrition in donor after brain deaths (DBDs) has yet to be adequately discussed. The primary aim of this study was to investigate whether the nutritional intake in the 48 h before organ retrieval may play a role on the graft functional recovery assessed with Model for Early Allograft Function (MEAF) Score. METHODS: Single-center retrospective study evaluating all liver transplants performed at the University Hospital of Udine from January 2010 to August 2020. Patients receiving grafts from DBD donors fed with artificial enteral nutrition in the 48 h prior to organ procurement (EN-group) or who did not (No-EN-group). Caloric debt was calculated using the difference between the calculated caloric needs and the effective calories delivered through enteral nutrition. RESULTS: Livers from EN-group presented a lower mean MEAF score compared to the no-EN-group: 3.39 ± 1.46 versus 4.15 ± 1.51, respectively (p = .04). A positive correlation between caloric debt and the MEAF score was found within the overall population (r = .227, p = .043) as well as in EN-group (r = .306, p = .049). CONCLUSIONS: Donor's nutritional intake in the final 48 h before organ procurement correlates with MEAF score, and nutrition probably plays a positive role on the functional recovery of the graft. Large future randomized controlled trials are needed to confirm this preliminary results.

Dynamic changes of neutrophil-to-lymphocyte ratio in brain-dead donors and delayed graft function in kidney transplant recipients.

OBJECTIVES: Neutrophil-to-lymphocyte ratio (NLR) is a simple parameter implying the inflammatory status. We aimed to explore the association of brain-dead donor NLR change with delayed graft function (DGF) in kidney transplant recipients. METHODS: We retrospectively analyzed the data on 102 adult brain-dead donors and their corresponding 199 kidney transplant recipients (2018 - 2021). We calculated ΔNLR by subtracting the NLR before evaluating brain death from the preoperative NLR. Increasing donor NLR was defined as ΔNLR > 0. RESULTS: Forty-four (22%) recipients developed DGF after transplantation. Increasing donor NLR was significantly associated with the development of DGF in recipients (OR 2.8, 95% CI 1.2 - 6.6; p = .018), and remained significant (OR 2.6, 95% CI 1.0 - 6.4; p = .040) after adjustment of confounders including BMI, hypertension, diabetes, and the occurrence of cardiac arrest. When acute kidney injury (AKI) was included in the multivariable analysis, increasing donor NLR lost its independent correlation with DGF, while AKI remained an independent risk factor of recipient DGF (OR 4.5, 95% CI 2.7 - 7.6; p < .001). The area under the curve of combined increasing NLR and AKI in donors (0.873) for predicting DGF was superior to increasing donor NLR (0.625, p = .015) and AKI alone (0.859, p < .001). CONCLUSIONS: Dynamic changes of donor NLR are promising in predicting post-transplant DGF. It will assist clinicians in the early recognition and management of renal graft dysfunction. Validation of this new biomarker in a large study is needed.

Processing methods for human amniotic membrane as scaffold for tissue engineering with mesenchymal stromal human cells.

Tissue engineering is an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve tissue function. The aims of this work were to compare chemically and physically processed human Amniotic Membranes (hAM) and analyze the cytocompatibility and proliferation rate (PR) of two primary human mesenchymal stromal cell lines, from different sources and donor conditions seeded over these scaffolds. The evaluated hAM processes were: cold shock to obtain a frozen amniotic membrane (FEAM) with remaining dead epithelial cells, denudation of hAM with trypsin for 20/10 min (DEAM20/10) or treatment with sodium dodecyl sulfate to decellularized hAM (DAM). All samples were sterilized with gamma radiation. The selection of the treated hAM to then generate composites was performed by scanning and transmission electron microscopy and characterization by X-ray diffraction, selecting DEAM10 and FEAM as scaffolds for cell seeding. Two sources of primary human stromal cells were used, both developed by our researchers, human Dental Pulp Stem Cells (hDPSC) from living donors and human Mesenchymal Stromal Cells (hMSC) from bone marrow isolated from brain dead donors. This last line of cells conveys a novel source of human cells that, to our knowledge, have not been tested as part of this type of construct. We developed four in vitro constructs without cytotoxicity signs and with different PR depending on the scaffolds and cells. hDPSC and hMSC grew over both FEAM and DEAM10, but DEAM10 allowed higher PR.

Giving, receiving and forgetting? On the social conditions of receiving an anonymous face transplant.

In 2004, the French National Consultative Ethics Committee expressed strong misgivings about the proposal to include the face among body parts that can be removed from deceased donors for organ transplantation. Yet, the first face transplant was performed a few months later. How do medical teams and patients deal with the singular nature of the face? I argue that what the face represents - from the medium of the donor's personal identity to an interchangeable organ - is not fixed. It emerges through the practices and can evolve through the interactions between medical professionals and patients. In the postoperative time, I show that patients receive potentially contradictory recommendations about how to integrate the organ: to consider it theirs and forget the donor, but also to thank the donor for the donation and never forget the origin of the graft. Based on the plurality of relationships developed by the patients with their donor, I revisit Maussian interpretative analyses of organ reception. The effects of giving a face vary both in terms of reciprocity and identity: the feeling of debt is variably felt and can be interpreted negatively or positively, and the experience is more or less transformative.

Feasibility of lung transplantation from donors mechanically ventilated for prolonged periods.

PURPOSE: When patients are mechanically ventilated for more than 5 days, they are usually declined as donors for lung transplantation (LTx); thus, the long-term outcomes of LTx from such donors remain unclear. We investigated the feasibility of LTx from donors that had been mechanically ventilated for prolonged periods. METHODS: The subjects of this retrospective comparative investigation were 31 recipients of LTx from donors who had been mechanically ventilated for < 5 days (short-term group) and 50 recipients of LTx from donors who had been mechanically ventilated for ≥ 5 days (long-term group). RESULTS: The median duration of donor mechanical ventilation was 3 days in the short-term group and 8.5 days in the long-term group. However, other than the difference in the duration of donor ventilation, there were no significant differences in the clinical characteristics of the donors or recipients between the groups. The overall survival rate after LTx was comparable between the long-term group and short-term group (5-year survival rate, 66.6% vs. 75.2%). CONCLUSION: The potential inclusion of donors who have been on mechanical ventilation for more than 5 days could be a feasible strategy to alleviate donor organ shortage.

Dopamine in transplantation: Written off or comeback with novel indication?

Renal-dose dopamine has fallen out of favor in the intensive care unit (ICU) during past years due to its ineffectiveness to prevent impending or to ameliorate overt renal failure in the critically ill. By contrast, growing evidence indicates that low-dose dopamine administered to the stable organ donor after brain death confirmation improves the clinical course of transplanted organs after kidney and heart transplantation. Ensuring a thorough monitoring for potential circulatory side effects, employment of dopamine at a dose of 4 µg/kg/min is safe in the deceased donor. Among recipients, the advantageous effect is easy to achieve, inexpensive, and devoid of adverse side effects. The mode of action relies on dopamine's propensity to mitigate injury in various cell systems from isolated transplantable organs under cold storage conditions. The present review article summarizes the clinical evidence of dopamine donor pretreatment in solid organ transplantation and focuses on the underlying molecular mechanisms of cellular protection. Introducing the routine use of low-dose dopamine for the management of the brain-dead donor in the ICU before procurement provides an evidence-based strategy to improve graft outcome after kidney transplantation without conferring harm to non-renal grafts, namely to livers and hearts, in cases of multi-organ donation.

A 25-year experience of kidney transplantation in Thailand: report from the Thai Transplant Registry.

AIM: To report the kidney transplant activity and survival data during the past 25 years from the Thai Transplant Registry. METHODS: By using the registry database that was collected and updated yearly by 26 transplant centres across the country, we have reported the donor, recipient, and transplant characteristics during the past 25 years from 1987 to 2012. The primary outcome was graft loss that was defined as return to dialysis, graft removal, retransplant, or patient death. RESULTS: 465 kidney transplants were performed in 2012, an 8.1% and 23.0% increase in living and deceased donor transplants compared to the previous year, respectively. Between 1987 and 2012 with the data of 3808 recipients, patient survival and graft survival improved significantly. Traffic accident was the most common cause of death in brain-dead donors. Additionally, the most common cause of end-stage kidney disease was glomerulonephritis. Infection has been among the most common causes of death in kidney transplant recipients. CONCLUSION: We have reported the total number, the graft and the patient survival data of kidney transplant recipients in Thailand for the period from 1987 to 2012. Although the number of patients is much lower than that in the developed countries, the patients and the graft survival rates are comparable.

Use of a novel donor lung scoring system as a tool for increasing lung recovery for transplantation.

OBJECTIVE: There is a critical shortage of donor lungs for transplantation. We previously developed a parsimonious, highly discriminatory nine-variable Lung Donor (LUNDON) acceptability score. We assess the utility of this score as a tool to improve lung recovery rates for transplantation. METHODS: We examined all brain-dead donors between 2014-2020 from three US organ procurement organizations and validated the score's predictive performance. We examined the trajectory of donors with low (<40) and high (>60) initial LUNDON scores, their corresponding lung recovery rates, factors contributing to score improvement using multivariable regression models, and one-year post-transplant recipient survival. RESULTS: Overall lung recovery was 32.4% (1410/4351). Validation of the LUNDON score in our cohort revealed a C statistic of 0.904 but required intercept calibration. Low initial LUNDON donors that improved to a high final score had an increase in lung recovery rate from 29.3% (1100/3765) to 86.8% (441/508), associated with lower BMI, management in specialized donor care facilities (SDCF), and more bronchoscopies. Donors with high initial and final LUNDON scores had lung recovery rate of 85.2% (98/115), associated with shorter lengths of stay. One-year survival was similar between recipients of low-to-high versus high-to-high LUNDON score donors (0.89 vs 0.84, p=0.2). CONCLUSIONS: The LUNDON score performs well as a predictor of lung recovery in a contemporary cohort but may require OPO-specific calibration. SDCF use, more bronchoscopies, and expediting time from brain death to organ procurement may improve lung utilization. The LUNDON score can be used to guide donor management to expand the donor pool.

Living-donor lobar lung transplantation.

Living-donor lobar lung transplantation (LDLLT) has become an important life-saving option for patients with severe respiratory disorders, since it was developed by a group in the University of Southern California in 1993 and introduced in Japan in 1998 in order to address the current severe shortage of brain-dead donor organs. Although LDLLT candidates were basically limited to critically ill patients who would require hospitalization, the long-term use of steroids, and/or mechanical respiratory support prior to transplantation, LDLLT provided good post-transplant outcomes, comparable to brain-dead donor lung transplantation in the early and late phases. In Kyoto University, the 5- and 10-year survival rates after LDLLT were reported to be 79.0% and 64.6%, respectively. LDLLT should be performed under appropriate circumstances, considering the inherent risk to the living donor. In our transplant program, all living donors returned to their previous social lives without any major complications, and living-donor surgery was associated with a morbidity rate of <15%. Both functional and anatomical size matching were preoperatively performed between the living-donor lobar grafts and recipients. Precise size matching before surgery could provide a favorable pulmonary function and exercise capacity after LDLLT. Various transplant procedures have recently been developed in LDLLT in order to deal with the issue of graft size mismatching in recipients, and favorable post-transplant outcomes have been observed. Native upper lobe-sparing and/or right-to-left inverted transplantation have been performed for undersized grafts, while single-lobe transplantation has been employed with or without contralateral pneumonectomy and/or delayed chest closure for oversized grafts.

Efficacy of three-dimensional computed tomography volumetry for recipients in downsizing oversized grafts in brain-dead donor lung transplantation.

OBJECTIVE: Brain-dead donor lung transplantation frequently requires reduction in the size of oversized lung grafts for patients with a small chest cavity. We focused on the role of three-dimensional computed tomography (3D-CT) volumetry for recipients on downsizing oversized lung grafts. METHODS: We performed 53 brain-dead donor bilateral lung transplantations, including 15 lobar lung transplants (Lobar group) and 38 standard lung transplants with full-sized grafts (Full group), between December 2010 and December 2018. Recipient chest volume before transplantation was measured using 3D-CT volumetry, and donor lung volume was evaluated by predicted total lung capacity. Post-transplant outcomes and pulmonary function were retrospectively compared between the groups. RESULTS: The ratio of the recipient chest volume to the donor lung volume was significantly lower in the Lobar group (0.42 ± 0.15) than in the Full group (0.77 ± 0.30, P < 0.01). The calculated size matching between the donor and recipient after downsizing the grafts was significantly correlated to the ratio of the recipient chest volume to the donor lung volume (Spearman r = 0.69; P < 0.01). Early post-transplant outcomes did not significantly differ between the groups. Although the Full group showed slightly better pulmonary function after transplantation, the 1-, 3-, and 5-year overall survival rates were similar to the Lobar group (100%, 93%, and 81% in the Lobar group vs. 92%, 78%, and 70% in the Full group; P = 0.50). CONCLUSIONS: Brain-dead donor lobar lung transplantation showed favorable post-transplant outcomes. The assessment of recipient chest cavity volume using 3D-CT volumetry may help surgeons precisely downsize oversized lung grafts prior to transplantation.

Prolonged warm ischemia exacerbated acute rejection after lung transplantation from donation after cardiac death in a mouse.

OBJECTIVE: In lung transplantation (LTx) from donation after cardiac death (DCD), the donor lungs are inevitably exposed to warm ischemic time (WIT) between the cardiac arrest and the initiation of cold preservation. We conducted this study to examine the effect of prolonged WIT on lung allograft rejection in a murine model of LTx from DCD. METHODS: Allogeneic BALB/c → B6 LTx from DCD was performed with a WIT of 15 min (WIT15 group, n = 5) or 60 min (WIT60 group, n = 5). Recipients were immunosuppressed by perioperative costimulatory blockade. The lung allografts were analyzed by histology and flow cytometry on day 7 after the LTx. RESULTS: Histologically, the rejection grade in the WIT60 group was significantly higher than that in the WIT15 group (3.4 ± 0.4 vs. 2.2 ± 0.2, P = 0.0278). Moreover, the intragraft CD8+ to CD4+ T cell ratio in the WIT60 group was significantly higher than that in the WIT15 group (2.3 ± 0.12 vs. 1.2 ± 0.11, P < 0.0001). CONCLUSIONS: Prolonged WIT could exacerbate the severity of lung allograft rejection after LTx from DCD. Minimization of the WIT could improve the outcomes after LTx from DCD.

The Outcomes of Pancreatic Transplantation from Pediatric Donors-A Single Institution Experience.

OBJECTIVES: The aim of this study was to compare the outcomes of pancreatic transplantation from pediatric donors younger than 15 years of age to the outcomes of pancreatic transplantation from adult donors. METHODS: Sixty patients underwent pancreatic transplantation in our facility from August 2012 to June 2019. These patients were divided into two groups according to the age of the donor: Cases in which the donor was younger than 15 years of age were classified into the PD group (n = 7), while those in which the donor was older than 15 years of age were classified into the AD group (n = 53). The outcomes of pancreas transplantation were retrospectively compared between the two groups. RESULTS: Pancreatic graft survival did not differ between the PD and AD groups. Furthermore, there were no differences in the HbA1c and serum creatinine levels at three months, with good values maintained in both groups. The results of oral glucose tolerance tests (OGTTs) revealed that the blood glucose concentration did not differ between the two groups. However, the serum insulin concentration at 30 min after 75 g glucose loading was significantly higher in the PD group. CONCLUSION: The outcomes of pancreatic transplantation from pediatric donors may be comparable to those of pancreatic transplantation from adult donors and the insulin secretion ability after transplantation may be better.

The Effects of Using Pancreases Obtained from Brain-Dead Donors for Clinical Islet Transplantation in Japan.

BACKGROUND: The pool of brain-dead donors (BDDs) was increased with the revision to the relevant law in 2010, and islet transplantation from BDDs was started in 2013. The present study assessed the influence of using pancreases from BDDs on islet transplantation in Japan. METHODS: The donor information registered with the secretariat of islet transplants from 2012 was reviewed, and the results of 86 clinical islet isolations performed in Japan between 2003 and 2018 with non-heart-beating donors (NHBDs) (n = 71) and BDDs (n = 15) were investigated. RESULTS: The number of cases for which donor information was registered with the secretariat of islet transplants increased to 1.84 cases/month from 2013 to 2018 in comparison to 1.44/month in 2012, when only NHBDs were used. The median pancreatic islet yield was 275,550 IEQ (Islet equivalents) in the NHBD group but 3,627,000 in the BDD group, which amounted to a statistically significant difference (p = 0.02). As a result, 38/71 cases (53.5%) were achieved successful islet isolation (>5000 IEQ per recipient weight (kg)) was achieved in 38/71 cases (53.5%) in the NHBD group, and 12/15 cases (80.0%) in the BDD group; thus, the rate of successful islet transplantation was higher in the BDD group. CONCLUSION: The use of pancreases from BDDs has increased the overall number of cases for which donor information is registered with the secretariat of islet transplants and has improved the performance of islet isolation, thereby increasing the probability of successfully achieving islet transplantation.

Brain death-associated pathological events and therapeutic options.

BACKGROUND: At present, organ transplantation is the most efficient treatment of end-stage failure of various organs, including the heart, lungs, pancreas, intestines, kidney, and liver. Despite the efforts to use organs from living donors or from donors after circulatory death, most of the organs are recovered from brain dead (BD) donors. METHODS: The Medline and Web of Science databases were searched without time limit on November 2015 using the terms "brain dead donor" and "deceased donor" in conjunction with "transplantation", "graft", "organ", "hemodynamic", "hormonal", or "management". The search was limited to the English, Polish and Spanish literature. Articles that did not address the topics were excluded and the full text of the remaining articles was reviewed. RESULTS: It is well established that brain death is associated with a cascade of hemodynamic, inflammatory, and immunologic events that affect the outcome of transplanted organs. Proper management of the potential organ donor may help increase the supply of organs for transplantation. However, because there is a lack of good quality evidence, it is difficult to establish specific BD donor management guidelines. CONCLUSION: In this paper we present a review of studies and literature concerning the detrimental impact of donor brain death on graft function. We present pathologic changes that take place after brain death, their influence on graft quality and therapeutic solutions to enhance transplanted organ function.

Effects of Dopamine Donor Pretreatment on Graft Survival after Kidney Transplantation: A Randomized Trial.

BACKGROUND AND OBJECTIVES: Donor dopamine improves initial graft function after kidney transplantation due to antioxidant properties. We investigated if a 4 µg/kg per minute continuous dopamine infusion administered after brain-death confirmation affects long-term graft survival and examined the exposure-response relationship with treatment duration. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Five-year follow-up of 487 renal transplant patients from 60 European centers who had participated in the randomized, multicenter trial of dopamine donor pretreatment between 2004 and 2007 (ClinicalTrials.gov identifier: NCT00115115). RESULTS: Follow-up was complete in 99.2%. Graft survival was 72.6% versus 68.7% (P=0.34), and 83.3% versus 80.4% (P=0.42) after death-censoring in treatment and control arms according to trial assignment. Although infusion times varied substantially in the treatment arm (range 0-32.2 hours), duration of the dopamine infusion and all-cause graft failure exhibited an exposure-response relationship (hazard ratio, 0.96; 95% confidence interval [95% CI], 0.92 to 1.00, per hour). Cumulative frequency curves of graft survival and exposure time of the dopamine infusion indicated a maximum response rate at 7.10 hours (95% CI, 6.99 to 7.21), which almost coincided with the optimum infusion time for improvement of early graft function (7.05 hours; 95% CI, 6.92 to 7.18). Taking infusion time of 7.1 hours as threshold in subsequent graft survival analyses indicated a relevant benefit: Overall, 81.5% versus 68.5%; P=0.03; and 90.3% versus 80.2%; P=0.04 after death-censoring. CONCLUSIONS: We failed to show a significant graft survival advantage on intention-to-treat. Dopamine infusion time was very short in a considerable number of donors assigned to treatment. Our finding of a significant, nonlinear exposure-response relationship disclosed a threshold value of the dopamine infusion time that may improve long-term kidney graft survival.

An intensive lung donor treatment protocol does not have negative influence on other grafts: a multicentre study.

OBJECTIVES: Competing requirements for organ perfusion may call for antagonistic strategies such as fluid replacement or high positive end-expiratory pressure. We recently proposed an intensive lung donor treatment protocol that nearly tripled lung procurement rates and validated it in a multicentre study. The next step was to evaluate the impact of our proposal on the other organ grafts recovered from lung donors and on the recipients' outcome after transplantation of those grafts. METHODS: A quasi-experimental study was conducted in six Spanish hospitals during 2013 (2010-12 was historical control). Organ donor management was led by a trained and experienced intensive care staff. RESULTS: A total of 618 actual donors after brain death (DBDs) were included, 453 DBDs in the control period (annual average 151) and 165 in the protocol period. No baseline differences were found between the periods. Heart, liver, kidney and pancreas retrieval rates were similar in both periods, and heart, liver, kidney and pancreas recipients' survival at 3 months showed no differences between both periods. CONCLUSIONS: Our lung donor treatment protocol is safe for other grafts obtained from donors undergoing these procedures with the aim of increasing lungs available for transplantation. It has no negative impact on the recovery rates of other grafts or on early survival of heart, liver, pancreas or kidney recipients.

The First Experience of Ex-Vivo Lung Perfusion (EVLP) in Iran: An Effective Method to Increase Suitable Lung for Transplantation.

BACKGROUND: Although lung transplantation is a well-accepted treatment for end-stage lung diseases patients, only 15%-20% of the brain-dead donors' lungs are usable for transplantation. This results in high mortality of candidates on waiting lists. Ex-vivo lung perfusion (EVLP) is a novel method for better evaluation of a potential lung for transplantation. OBJECTIVE: To report the first experience of EVLP in Iran. METHODS: The study included a pig in Vienna Medical University, Vienna, Austria, and 4 humans in Masih Daneshvari Hospital, Tehran, Iran. All brain-dead donors from 2013 to 2015 in Tehran were evaluated for EVLP. Donors without signs of severe chest trauma or pneumonia, with poor oxygenation were included. RESULTS: An increasing trend in difference between the pulmonary arterial pO2 and left atrial pO2, an increasing pattern in dynamic lung compliance, and a decreasing trend in the pulmonary vascular resistance, were observed. CONCLUSION: The initial experience of EVLP in Iran was successful in terms of important/critical parameters. The results emphasize on some important considerations such as precisely following standard lung harvesting and monitoring temperature and pressure. EVLP technique may not be a cost-effective option for low-income countries at first glance. However, because this is the only therapeutic treatment for end-stage lung disease, it is advisable to continue working on this method to find alternatives with lesser costs.

Single institution outcomes in the first 3 years of pancreas transplantation from brain dead donors.

BACKGROUND: A total of 26 pancreas transplants from brain dead donors, including 21 simultaneous pancreas and kidney (SPK) transplantation procedures, have been performed at Fujita Health University Hospital since the new pancreas transplant program was initiated in August 2012. The objective of this study is to investigate the outcomes of pancreatic transplantation in our facility in first 3 years of the program. METHODS: The background characteristics of the donors and the outcomes of 26 pancreas transplant recipients were analyzed. RESULTS: The mean age of the recipients was 44.0 years, and all recipients had a long-term history of diabetes (mean: 30.2 years). In the SPK cases, the patients also had a long history of hemodialysis (mean: 6.3 years). Although the average donor age was 41.0 years and more than half of the donors were marginal donors (defined according to Kapur's criteria and Troppmann's criteria), the patient survival and pancreatic graft survival rates were 100% and 91.7%, respectively. Unfortunately, two recipients experienced graft failure due to graft thrombosis, which resulted in graft loss. CONCLUSIONS: The new pancreas transplant program at Fujita Health University has provided excellent outcomes for patients with type 1 diabetes.
