Hemoderivative Transfusion in Liver Transplantation: Comparison Between Recipients of Grafts From Brain Death Donors and Recipients of Uncontrolled Donors After Circulatory Death.

[PMID: 34419255 DOI: 10.1016/j.transproceed.2021.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 06/07/2021] [Accepted: 07/12/2021] [Indexed: 11/19/2022]
Abstract
INTRODUCTION Intraoperative bleeding during liver transplantation has been correlated with a higher risk of morbidity and mortality and decrease in patient and graft survival. MATERIALS AND METHODS Between January 2006 and December 2016 we performed 783 orthotopic liver transplants. After applying exclusion criteria, we found liver grafts from donors after circulatory death (DCD, group A) were used in 69 patients and liver grafts from donors after brain death (group B) were used in 265 patients. RESULTS No difference was found in terms of sex, body mass index, Model for End-Stage Liver Disease score, indication for transplantation, intensive care unit stay, and Child-Pugh score. The mean transfusion of hemoderivates was as follows: red blood cell 9 (0-28) units in group A vs 6 (0-20) units in group B (P = .004) and fresh frozen plasma 10 (0-29) units in group A vs 9.5 (0-23) in group B (P = .000). The only 2 factors related to massive blood transfusion (>6 units of red blood cell) were uncontrolled DCD condition (odds ratio = 2.38; 95% confidence interval, 1.32-4.31; P = .004), and higher Model for End-Stage Liver Disease score (odds ratio = 2.63; 95% confidence interval, 1.53-4.55; P = .001). Survival at 1, 3, and 5 years was 81.3%, 70.2%, and 68.9% in group A vs 89%, 83.7%, and 78% in group B (P = .070). CONCLUSION The use of liver grafts from DCDs is associated with increased necessity of transfusion of hemoderivates in comparison with the use of liver grafts from donors after brain death.

Abstract
PURPOSE OF REVIEW Donation after circulatory death (DCD) is still performed in a limited number of countries. This article summarizes the development of DCD in Spain and presents recent Spanish contributions to gain knowledge on the potential benefits and the practical use of normothermic regional perfusion (nRP). RECENT FINDINGS DCD now contributes to 24% of deceased donors in Spain. The development of DCD has been based on an assessment of practices in the treatment of cardiac arrest and end-of-life care to accommodate the option of DCD; the creation of an adequate regulatory framework; and institutional support, professional training and public education. Appropriate posttransplant outcomes have been obtained with organs from both uncontrolled and controlled DCD donors. nRP is increasingly used, with preliminary data supporting improved results compared with other in-situ preservation/recovery approaches. Mobile teams with portable extracorporeal membrane oxygenation devices are making nRP possible in hospitals without these resources. To avoid the possibility of reestablishing brain circulation after the determination of death, a specific methodology has been validated. SUMMARY DCD has been successfully developed in Spain following a streamlined process. nRP may become a standard in DCD, although further evidence on the benefits of this technology is eagerly awaited.

Abstract
The shortage of organs remains one of the biggest challenges in transplantation. To address this, we are increasingly turning to donation after circulatory death (DCD) donors and now in some countries to uncontrolled DCD donors. We consolidate the knowledge on uncontrolled DCD in Europe and provide recommendations and guidance for the development and optimization of effective uncontrolled DCD programmes.

Abstract
The renewed interest in donation after cardio-circulatory death (DCD) started in the 1990s following the limited success of the transplant community to expand the donation after brain-death (DBD) organ supply and following the request of potential DCD families. Since then, DCD organ procurement and transplantation activities have rapidly expanded, particularly for non-vital organs, like kidneys. In liver transplantation (LT), DCD donors are a valuable organ source that helps to decrease the mortality rate on the waiting lists and to increase the availability of organs for transplantation despite a higher risk of early graft dysfunction, more frequent vascular and ischemia-type biliary lesions, higher rates of re-listing and re-transplantation and lower graft survival, which are obviously due to the inevitable warm ischemia occurring during the declaration of death and organ retrieval process. Experimental strategies intervening in both donors and recipients at different phases of the transplantation process have focused on the attenuation of ischemia-reperfusion injury and already gained encouraging results, and some of them have found their way from pre-clinical success into clinical reality. The future of DCD-LT is promising. Concerted efforts should concentrate on the identification of suitable donors (probably Maastricht category III DCD donors), better donor and recipient matching (high risk donors to low risk recipients), use of advanced organ preservation techniques (oxygenated hypothermic machine perfusion, normothermic machine perfusion, venous systemic oxygen persufflation), and pharmacological modulation (probably a multi-factorial biologic modulation strategy) so that DCD liver allografts could be safely utilized and attain equivalent results as DBD-LT.

Abstract
PURPOSE To describe technical aspects of a new experimental model that simulates a non heart beating organ donor. METHODS Landrace pigs were operated on and cardiac arrest was obtained by means of myocardial infarction and interruption of ventilator support. RESULTS Mean cardiac frequency, systolic and diastolic blood pressure levels, central venous pressure, oxygen saturation and concentration of expired CO(2) dropout occurred at seven minutes after cardiac arrest. CONCLUSION The procedure was easily reproduced and a homogeneous circulatory failure could de obtained by the end of seven minutes. The model is suitable for further studies regarding abdominal organ transplantation.

Abstract
The last decade saw increased organ donation activity from donors after cardiac death (DCD). This contributed to a significant proportion of transplant activity. Despite certain drawbacks, liver transplantation from DCD donors continues to supplement the donor pool on the backdrop of a severe organ shortage. Understanding the pathophysiology has provided the basis for modulation of DCD organs that has been proven to be effective outside liver transplantation but remains experimental in liver transplantation models. Research continues on how best to further increase the utility of DCD grafts. Most of the work has been carried out exploring the use of organ preservation using machine assisted perfusion. Both ex-situ and in-situ organ perfusion systems are tested in the liver transplantation setting with promising results. Additional techniques involved pharmacological manipulation of the donor, graft and the recipient. Ethical barriers and end-of-life care pathways are obstacles to widespread clinical application of some of the recent advances to practice. It is likely that some of the DCD offers are in fact probably “prematurely” offered without ideal donor management or even prior to brain death being established. The absolute benefits of DCD exist only if this form of donation supplements the existing deceased donor pool; hence, it is worthwhile revisiting organ donation process enabling us to identify counter remedial measures.

Abstract
BACKGROUND Although non-heart-beating donors have the potential to increase the number of available organs, the livers are used very seldom because of the risk of primary non-function. There is evidence that machine perfusion is able to improve the preservation of marginal organs, and therefore we evaluated in our study the influence of the perfusate temperature during oxygenated machine perfusion on the graft quality. METHODS Livers from male Wistar rats were harvested after 60-min warm ischemia induced by cardiac arrest. The portal vein was cannulated and the liver flushed with Lifor (Lifeblood Medical, Inc.) organ preservation solution for oxygenated machine perfusion (MP) at 4, 12 or 21 degrees C. Other livers were flushed with HTK and stored at 4 degrees C by conventional cold storage (4 degrees C-CS). Furthermore two groups with either warm ischemic damage only or without any ischemic damage serve as control groups. After 6h of either machine perfusion or cold storage all livers were normothermic reperfused with Krebs-Henseleit buffer, and functional as well as structural data were analyzed. RESULTS Contrary to livers stored by static cold storage, machine perfused livers showed independently of the perfusate temperature a significantly decreased enzyme release of hepatic transaminases (ALT) during isolated reperfusion. Increasing the machine perfusion temperature to 21 degrees C resulted in a marked reduction of portal venous resistance and an increased bile production. CONCLUSIONS Oxygenated machine perfusion improves viability of livers after prolonged warm ischemic damage. Elevated perfusion temperature of 21 degrees C reconstitutes the hepatic functional capacity better than perfusion at 4 or 12 degrees C.

Abstract
Because of the organ shortage, non-heart-beating donors have been proposed as a possible source of grafts for orthotopic liver transplantation (OLT). Despite the widespread use of controlled non-heart-beating donors, there are only a few published studies reporting the outcomes with uncontrolled non-heart-beating donors (UNHBDs). A prospective case-control study on adult patients undergoing OLT was designed. We used normothermic extracorporeal membrane oxygenation (NECMO) in all UNHBDs. Matching 2:1 ratio comparison was performed between a study group (UNHBDs) and a brain death donor (BDD) control group. Between January 2006 and March 2008, a total of 60 patients were included: 20 in the UNHBD group and 40 in the control group. The incidence of ischemic cholangiopathy was 5% (n = 1) for the UNHBD group and 0% for the BDD group (P = 0.15). The rate of primary nonfunction was 10% (n = 2) in UNHBD recipients and 2.5% (n = 1) in BDD recipients (P = 0.21), with graft loss in all of them. Three patients were retransplanted in the UNHBD group (15%), 2 of them because of primary nonfunction and 1 because of ischemic cholangiopathy; no patient was retransplanted in the control group (P = 0.012). After a mean follow-up of 330.4 +/- 224.9 days, 1-year cumulative patient survival was 85.5% for the UNHBD group and 87.5% for the BDD group (P = 0.768). One-year cumulative graft survival was 80% in the UNHBD group and 87.5% in the BDD group (P = 0.774). In conclusion, UNHBDs under NECMO are a potential source of organs for OLT with encouraging outcomes potentially comparable to those obtained with BDDs.

Abstract
Hepatitis C (HCV)-related end-stage liver disease is the most common indication for liver transplantation. Safe expansion of the donor pool with improved rates of deceased donation and more widespread use of living and extended criteria donation are likely to decrease wait list mortality. In addition, improved antiviral treatments and a better understanding of the delicate balance between under- and over-immunosuppression in this population are needed. Finally, when recurrent advanced fibrosis occurs, the criteria for patient selection for retransplantation remain widely debated. This article reviews the literature on these topics and the work being done in each area to maximize outcomes in patients receiving transplants for HCV-related cirrhosis.

Abstract
UNLABELLED Mortality on liver transplantation (OLT) waiting lists has increased dramatically. Until recently, non-heart-beating donors (NHBD) were not considered suitable for OLT, because of a higher risk of primary graft nonfunction (PNF) and biliary strictures. However, recent experimental/clinical evidence has indicated that NHBD-OLT is feasible when the period of warm ischemia is short. PURPOSE To characterize the results of NHBD-OLT in Belgium, a survey was sent to all Belgian OLT centers. RESULTS Between January 2003 and November 2005, 16 livers originating from NHBD were procured and transplanted. The mean donor age was 48.8 years, including 9 males and 7 females with mean time of stop-therapy to cardiac arrest being 18 minutes and from cardiac arrest to liver cold perfusion, 10.5 minutes. Mean recipient age was 52.2 years including 12 males and 4 females. Mean cold ischemia time was 7 hours 15 minutes. No PNF requiring re-OLT was observed. Mean post-OLT peak transaminase was 2209 IU/L, which was higher among imported versus locally procured grafts. Biliary complications occurred in 6 patients requiring re-OLT (n = 2), endoscopic treatment (n = 2), surgical treatment (n = 1), or left untreated (n = 1). These tended to be more frequent after prolonged warm ischemia. Graft and patient survivals were 62.5% and 81.3%, respectively, with a follow-up of 3 to 36 months. CONCLUSION This survey showed acceptable graft/patient survivals after NHBD-LT. The NHBD-liver grafts suffered a high rate of ischemic injury and biliary complications and therefore should be used carefully, namely with no additional donor risk factors, lower risk recipients, and short cold/warm ischemia.

Abstract
Recent commentaries by Verheijde et al, Evans and Potts suggesting that donation after cardiac death practices routinely violate the dead donor rule are based on flawed presumptions. Cell biology, cardiopulmonary resuscitation, critical care life support technologies, donation and transplantation continue to inform concepts of life and death. The impact of oxygen deprivation to cells, organs and the brain is discussed in relation to death as a biological transition. In the face of advancing organ support and replacement technologies, the reversibility of cardiac arrest is now purely related to the context in which it occurs, in association to the availability and application of support systems to maintain oxygenated circulation. The 'complete and irreversible' lexicon commonly used in death discussions and legal statutes are ambiguous, indefinable and should be replaced by accurate terms. Criticism of controlled DCD on the basis of violating the dead donor rule, where autoresuscitation has not been described beyond 2 minutes, in which life support is withdrawn and CPR is not provided, is not valid. However, any post mortem intervention that re-establishes brain blood flow should be prohibited. In comparison to traditional practice, organ donation has forced the clarification of the diagnostic criteria for death and improved the rigour of the determinations.

Abstract
The purpose of this study was to ascertain whether abdominal compression with an inflatable abdominal band, a device we developed, improved post-dialytic orthostatic hypotension (OH) in hemodialysis (HD) patients. Twenty-five chronic HD patients with intractable post-dialytic OH were recruited. Post-HD changes in systolic blood pressure (DeltaSBP) in the supine and standing positions were compared in the patients, measured with or without the use of the band. The study showed DeltaSBP after HD without the band was significantly greater than that measured before HD (-36.1+/-18.2 vs -13.1+/-16.8 mm Hg; P<0.0001). DeltaSBP after HD with the band was reduced significantly in comparison to DeltaSBP after HD without the band (-19.4+/-21.2 vs -36.1+/-18.2 mm Hg; P<0.002). Use of the band did not cause an elevation in SBP in the supine position (149.0+/-29.6 vs 155.4+/-25.7 mm Hg); however, it did increase SBP upon standing (129.6+/-27.3 vs 117.2+/-22.6 mm Hg; P<0.05). Eight patients in whom an increase in SBP of 25 mm Hg or more was achieved with the band were classified as responders. Ejection fraction was significantly higher (76.4+/-11.1 vs 61.9+/-13.6%; P<0.02) and atrial natriuretic peptide concentration significantly lower (27.9+/-22.0 vs 68.9+/-47.5 pg/ml; P<0.02) in responders than in non-responders. We conclude that the abdominal band was effective for overcoming post-dialytic OH, without elevating supine SBP in some patients.

Abstract
Hepatitis C virus (HCV) infection remains the most common cause of hepatic failure requiring orthotopic liver transplantation, and the disparity between the number of patients in need of liver replacement and the number of organs available continues to grow. Unfortunately, without viral eradication before transplantation, HCV recurrence is universal and is associated with poor graft and patient survival. Despite expansion of the donor pool and attempts to suppress HCV activity with various pretransplant and posttransplant antiviral therapies, many questions remain. This article reviews the literature regarding the evaluation of patients for transplantation, the antiviral therapies available in the peritransplant period, the immunosuppressive regimens, used, and the approach to patients with recurrent HCV infection.
