Donor-derived infections among Chinese donation after cardiac death liver recipients

AIM To investigate blood cultures of deceased donors and report the confirmed transmission of bacterial infection from donors to liver recipients.METHODS We retrospectively studied the results of blood cultures among our donation after cardiac death(DCD) donors and calculated the donor-derived bacterial infection rates among liver recipients. Study participants underwent liver transplantation between January 1, 2010 and February 1, 2017. The study involved a total of 67 recipients of liver grafts from 67 DCD donors. We extracted the data of donors' and patients' characteristics, culture results and clinical outcomes, especially the post-transplant complications in liver recipients, from electronic medical records. We analyzed the characteristics of the donors and the corresponding liver recipients with emphasis put on donor-derived infections.RESULTS Head trauma was the most common origin of death among our 67 DCD donors(46.3%). Blood taken prior to the procurement operation was cultured for 53 of the donors, with 17 episodes of bloodstream infections developing from 13 donors. The predominant organism isolated from the blood of donors was Gram-positive bacteria(70.6%). Only three(4.5%) of 67 liver recipients developed confirmed donor-derived bacterial infections,with two isolates of multidrug-resistant Klebsiella pneumoniae and one isolate of multidrug-resistant Enterobacter aerogenes. The liver recipients with donorderived infections showed relation to higher crude mortality and graft loss rates(33.3% each) within 3 mo post transplantation, as compared to those without donor-derived infections(9.4% and 4.7%, respectively). All three liver recipients received appropriate antimicrobial therapy.CONCLUSION Liver recipients have high occurrence of donor-derived infections. The liver recipients with donor-derived multidrug-resistant Enterobacteriaceae infections can have good outcome if appropriate antimicrobial therapy is given.

Tauroursodeoxycholic acid and 4-phenyl butyric acid alleviate endoplasmic reticulum stress and improve prognosis of donation after cardiac death liver transplantation in rats

BACKGROUND： Inevitable warm ischemia time before organ procurement aggravates posttransplantation ischemia- reperfusion injury. Endoplasmic reticulum （ER） stress is involved in ischemia-reperfusion injury, but its role in donation after cardiac death （DCD） liver transplantation is not clear and the effect of ER stress inhibitors, tauroursodeoxycholic acid （TUDCA） and 4-phenyl butyric acid （PBA）, on the prognosis of recipient of DCD liver transplantation remains unclear. METHODS： Male Sprague-Dawley rats （8-10 weeks） were randomly divided into control group： liver grafts without warm ischemia were implanted; DCD group： warm ischemia time of the liver grafts was 60 minutes; TUDCA and PBA groups： based on the DCD group, donors were intraperitoneally injected with TUDCA or PBA 30 minutes before the organ procurements. Serum aminotransferase levels, oxidative stress activation and expression of ER stress signal molecules were evaluated. Pathological examinations were performed. The survivals of the recipients in each group were compared for 14 days.RESULTS： Compared with the control group, DCD rats had significantly higher levels of serum aminotransferase at 6 hours, 1 day and 3 days after operation （P〈0.01, 0.01 and 0.05, respectively） and oxidative indices （P〈0.01 for both malondialdehyde and 8-hydroxy deoxyguanosine）, more severe liver damage （P〈0.01） and up-regulated ER stress signal expressions （P〈0.01 for GRP78, phos-eIF2al, CHOP, ATF-4, ATF-6, PERK, XBP-1 and pro-caspase-12）. All recipients died within 3 days after liver transplantation. Administration of TUDCA or PBA significantly decreased aminotransferase levels （P〈0.05）, increased superoxide dismutase activities （P〈0.01）, alleviated liver damage （P〈0.01）, down-regulated ER stress signal expressions （P〈0.01） and improved postoperative survivals （P〈0.01）. CONCLUSIONS： ER stress was involved with DCD liver trans- plantation in rats. Preoperative intraperitoneally injection of TUDCA or PBA protected ER stress and improved prognosis.

Pathological Characteristics of Liver Allografts from Donation after Brain Death Followed by Cardiac Death in Pigs

Donation after brain death followed by circulatory death （DBCD） is a unique practice in China. The aim of this study was to define the pathologic characteristics of DBCD liver allografts in a porcine model. Fifteen male pigs （25-30 kg） were allocated randomly into donation after brain death （DBD）, donation after circulatory death （DCD） and DBCD groups. Brain death was induced by aug- menting intracranial pressure. Circulatory death was induced by withdrawal of life support in DBCD group and by venous injection of 40 mL 10% potassium chloride in DCD group. The donor livers were perfused in situ and kept in cold storage for 4 h. Liver tissue and common bile duct samples were col- lected for hematoxylin and eosin staining, TUNEL testing and electron microscopic examination. Spot necrosis was found in hepatic parenchyma of DBD and DBCD groups, while a large area of necrosis was shown in DCD group. The apoptosis rate of hepatocytes in DBD [（0.56±0.30）%] and DBCD [（0.50 ±0.11）%] groups was much lower than that in DCD group [（3.78±0.33）%] （P〈0.05）. And there was no significant difference between DBD group and DBCD group （P〉0.05））. The structures of bile duct were intact in both DBD and DBCD groups, while the biliary epithelium was totally damaged in DCD group. Under electron microscope, the DBD hepatocytes were characterized by intact cell membrane, well-organized endoplasmic reticulum, mild mitochondria edema and abundant glycogens. Broken cell membrane, mild inflammatory cell infiltration and sinusoidal epithelium edema, as well as reduced glycogen volume, were found in the DBCD hepatocytes. The DCD hepatocytes had more profound cell organelle injury and much less glycogen storage. In conclusion, the preservation injury of DBCD liver allografts is much less severe than that of un-controlled DCD, but more severe than that of DBD liver allografts under electron microscope, which might reflect post-transplant liver function to some extent.

Kidney donation after cardiac death

There is continuing disparity between demand for and supply of kidneys for transplantation. This review describes the current state of kidney donation after cardiac death （DCD） and provides recommendations for a way forward. The conversion rate for potential DCD donors varies from 40%-80%. Compared to con-trolled DCD, uncontrolled DCD is more labour intensive, has a lower conversion rate and a higher discard rate. The super-rapid laparotomy technique involving direct aortic cannulation is preferred over in situ perfusion in controlled DCD donation and is associated with lower kidney discard rates, shorter warm ischaemia times and higher graft survival rates. DCD kidneys showed a 5.73-fold increase in the incidence of delayed graft function （DGF） and a higher primary non function rate compared to donation after brain death kidneys, but the long term graft function is equivalent between the two. The cold ischaemia time is a controllable factor that signifcantly infuences the outcome of allografts, for example, limiting it to 〈 12 h markedly reduces DGF. DCD kidneys from donors 〈 50 function like stan-dard criteria kidneys and should be viewed as such. As the majority of DCD kidneys are from controlled dona-tion, incorporation of uncontrolled donation will expand the donor pool. Efforts to maximise the supply of kid-neys from DCD include： implementing organ recovery from emergency department setting; improving family consent rate; utilising technological developments to optimise organs either prior to recovery from donors or during storage; improving organ allocation to ensure best utility; and improving viability testing to reduce primary non function.

Potential approaches to improve the outcomes of donation after cardiac death liver grafts

There is a growing discrepancy between the supply and demand of livers for transplantation resulting in high mortality rates on the waiting list. One of the options to decrease the mortality on the waiting list is to optimize organs with inferior quality that otherwise would be discarded. Livers from donation after cardiac death(DCD) donors are frequently discarded because they are exposed to additional warm ischemia time, and this might lead to primary-non-function, delayed graft function, or severe biliary complications. In order to maximize the usage of DCD livers several new preservation approaches have been proposed. Here, we will review 3 innovative organ preservation methods:(1) different ex vivo perfusion techniques;(2) persufflation with oxygen; and(3) addition of thrombolytic therapy. Improvement of the quality of DCD liver grafts could increase the pool of liver graft's for transplantation, improve the outcomes, and decrease the mortality on the waiting list.

Warm ischemia time and elevated serum uric acid are associated with metabolic syndrome after liver transplantation with donation after cardiac death

AIM To describe the prevalence of posttransplant metabolic syndrome(PTMS) after donation after cardiac death(DCD) liver transplantation(LT) and the pre-and postoperative risk factors.METHODS One hundred and forty-seven subjects who underwent DCD LT from January 2012 to February 2016 were enrolled in this study. The demographics and the clinical characteristics of pre-and post-transplantation were collected for both recipients and donors. PTMS was defined according to the 2004 Adult Treatment Panel-Ⅲ criteria. All subjects were followed monthly for the initial 6 mo after discharge, and then, every 3 mo for 2 years. The subjects were followed every 6 mo or as required after 2 years post-LT.RESULTS The prevalence of PTMS after DCD donor orthotopic LT was 20/147(13.6%). Recipient's body mass index(P = 0.024), warm ischemia time(WIT)(P = 0.045), and posttransplant hyperuricemia(P = 0.001) were significantly associated with PTMS. The change in serum uric acid levels in PTMS patients was significantly higher than that in non-PTMS patients(P < 0.001). After the 1 s t mo, the level of serum uric acid of PTMS patients rose continually over a period, while it was unaltered in non-PTMS patients. After transplantation, the level of serum uric acid in PTMS patients was not associated with renal function.CONCLUSION PTMS could occur at early stage after DCD LT with growing morbidity with the passage of time. WIT and post-LT hyperuricemia are associated with the prevalence of PTMS. An increased serum uric acid level is highly associated with PTMS and could act as a serum marker in this disease.

Successful Abdominal Organ Donation after Brain Death in a Patient with a Biventricular Assist Device: Extending Extended Criteria

Few studies address the potential for donation after brain death (DBD) in the limited population of patients with ongoing mechanical circulatory support (MCS). A case study was conducted reviewing available records of both donor and recipient, and available literature. The donor was a young female with an acute myocardial infarction precipitating emergent off-pump 2-vessel bypass graft complicated by profound cardiogenic shock refractory to inotropes and intra-aortic balloon pump. A heparin drip was started following percutaneous placement of a left ventricular-assist device (TandemHeart?) which improved her hemodynamics to stabilize for transfer. She ultimately required surgical placement of biventricular assist device (CentraMag?) to normalize hemodynamics. Two days post-operatively, she developed a cerebellar hemorrhage and was declared brain dead. Pre-donation blood chemistry showed adequate end-organ function. Both kidneys were placed locally. The liver was rejected for two regional status 1 patients and by all other local centers. We accepted the liver for a patient with polycystic liver disease with a MELD exception score of 20. The recipient is now 4 years post-transplant with excellent graft function. Extending donor criteria to include MCS patients can result in successful transplantation and should be considered in selected circumstances once satisfactory donor end-organ function is established.

The Dallas Donation after Circulatory Death Transplantation Summit:expanding donation after circulatory death procedures through process improvement,broader utilization,and innovation

Despite a significant increase in utilization over the past decade,the number of donation after circulatory death(DCD)organs that are procured and transplanted in the United States(US)remains well below its potential.There is still room for expansion,as utilizing DCD organs to the fullest extent is currently the most viable solution to the persistent mismatch between supply and demand in transplantation.We convened a multidisciplinary transplantation summit to examine various aspects of DCD,with faculty members from around the world with clinical and academic interest in DCD donation and transplantation,including abdominal and cardiothoracic surgeons,organ procurement organization directors,hepatologists,and gastroenterologists.The conference focused on identifying barriers to DCD organ utilization and strategies to overcome these barriers.We divide the barriers to DCD utilization into three mains categories:(Ⅰ)policy and process variation;(II)logistical and transportation challenges;and(Ⅲ)higher risk perceptions related to DCD outcomes.For each barrier,we proposed a variety of solutions,providing an overview of the status of DCD donation in the US and suggestions on how to increase the use of DCD.There is a specific focus on ex situ machine perfusion,normothermic regional perfusion,and other opportunities to expand DCD utilization without negatively impacting recipient outcomes.

Liver transplantation with grafts obtained after cardiac death-current advances in mastering the challenge

The scarcity of donor livers has increased the interest in donation after cardiac death(DCD) as an additional pool to expand the availability of organs. However, the initial results of liver transplantation with DCD grafts have been suboptimal due to an increased rate of complications, as well as decreased graft survival. These challenges have led to many developments in DCD donation outcome, as well as basic and translational research. In this article we review the unique characteristics of DCD donors, nuances of DCD organ procurement, the effect of prolonged warm and cold ischemia times, and discuss major studies that compared DCD to donation after brain death liver transplantation, in terms of outcomes and complications. We also review the different methods of donor treatment that has been applied to ameliorate DCD organ outcome, and we discuss the role of machine perfusion techniques in organ reconditioning. We discuss the two major perfusionmodels, namely, hypothermic machine perfusion and normothermic machine perfusion; we compare both methods, and delineate their major differences.
