OBJECTIVES: The use of marginal donors with cardiovascular risk factors is increasing due to organ shortage but remains controversial in heart transplantation (HTx). We sought to investigate post-transplant outcomes in the recent era taking into account donor characteristics. METHODS: We reviewed 261 HTx performed in our hospital between January 1996 and March 2013. Donor characteristics were obtained from the national database. The incidence of primary graft dysfunction (PGD) and cardiac allograft vasculopathy (CAV) and overall survival were compared in 2 groups of HTx recipients: those receiving transplants from 1996 to 2004 (Group A, n =  120) and from 2005 to 2013 (Group B, n =  141)...

PURPOSE OF REVIEW: As the number of people living with heart failure continues to grow, future treatments will focus on efficient donor organ donation and ensuring safe and durable outcomes. This review will focus on organ procurement, graft surveillance and emerging therapies. RECENT FINDINGS: Preliminary studies into donation after cardiac death have indicated that this may be an effective means to increase the donor pool. Novel preservation techniques that include ex-vivo perfusion to improve donor metabolic stabilization prior to implantation may also expand the donor pool...

The most common causes of death after heart transplantation (HTx) include acute rejection and multi-organ failure in the early period and malignancy and cardiac allograft vasculopathy (CAV) in the late period. Polyclonal antibody preparations such as rabbit anti-thymocyte globulin (ATG) may reduce early acute rejection and the later occurrence of CAV after HTx. ATG therapy depletes T cells, modulates adhesion and cell-signaling molecules, interferes with dendritic cell function, and induces B-cell apoptosis and regulatory and natural killer T-cell expansion...

AIMS: The role of donor/recipient gender matching on the long-term rejection process and clinical outcomes following heart transplantation (HT) outcomes is still controversial. We aim to investigate the impact of gender matching on early and long-term outcome HT. METHODS AND RESULTS: The study population comprised 166 patients who underwent HT between 1991 and 2013 and were prospectively followed up in a tertiary referral centre. Early and late outcomes were assessed by the type of donor-recipient gender match (primary analysis: female donor-male recipient [FD-MR, n = 36] vs...

PURPOSE OF REVIEW: Cardiac allograft vasculopathy (CAV) is a major limitation to long-term survival after heart transplantation. Innovative new techniques to diagnose CAV have been applied to detect disease. This review will examine the current diagnostic and treatment options available to clinicians for CAV. RECENT FINDINGS: Diagnostic modalities addressing the pathophysiology underlying CAV (arterial wall thickening and decreased coronary blood flow) improve diagnostic sensitivity when compared to traditional (angiography and dobutamine stress echocardiography) techniques...

As methods for human leukocyte antigens (HLA) antibody detection have evolved and newer solid phase assays are much more sensitive, the last 15 years has seen a renewed focus on the importance of HLA antibodies in solid organ transplant rejection. However, there is still much controversy regarding the clinical significance of antibody level as depicted by the mean fluorescence intensity of a patient's neat serum. Emerging techniques, including those that identify antibody level and function, show promise for the detection of individuals at risk of allograft rejection, determination of the effectiveness of desensitization prior to transplant, and for monitoring treatment of rejection...

BACKGROUND: Heme oxygenase-1 (HO-1) catalyses the degradation of heme to biliverdin, free iron and carbon monoxide. The promoter region contains a highly polymorphic (GT)n repeat, where shorter (GT)n repeat sequences are linked to higher transcriptional activity, which was shown to correlate with a cytoprotective effect. Higher HO-1 levels may protect from cardiac allograft vasculopathy. METHODS: Cardiac allograft recipients transplanted between 1988 and 2012 were analysed for the HO-1 (GT)n repeat polymorphism using PCR and DNA fragment analysis with capillary electrophoresis...

BACKGROUND: Cardiac allograft vasculopathy (CAV) remains an important cause of graft failure after heart transplantation (HT). Although many risk factors for CAV have been identified, there are no clinical prediction models that enable clinicians to determine each recipient's risk of CAV. METHODS: We studied a cohort of 14,328 heart transplant recipients whose data were reported to the International Society for Heart and Lung Transplantation Registry between 2000 and 2010...

BACKGROUND: Transplantation of sensitized recipients has been associated with increased risk of post-transplant complications. In 2010, the Canadian Cardiac Transplant Network (CCTN) created a unique status listing for highly sensitized heart transplant candidates. Status 4S listing requires calculated panel-reactive antibody (cPRA) level >80% as the sole listing criteria and enables geographic expansion of the donor pool by providing national access. In this study, we describe patient characteristics and outcomes of those transplanted as Status 4S in Canada...

BACKGROUND: -Antibody-mediated rejection (AMR) contributes to heart allograft loss. However, an important knowledge gap remains regarding the pathophysiology of AMR and how detection of immune activity, injury degree and stage could be improved by intragraft gene expression profiling. METHODS: -We prospectively monitored 617 heart transplant recipients referred from four French transplant centers (January 1st 2006 - January 1st 2011) for AMR. We compared patients with AMR (n=55) to a matched control group of 55 patients without AMR...

BACKGROUND: Proliferation signal inhibitors, such as sirolimus, are increasingly used in solid-organ transplantation. However, limited data exist on sirolimus-treated pediatric patients. We aimed to describe sirolimus use in pediatric heart transplant patients and test the hypothesis that sirolimus use is associated with improved outcomes. METHODS: A retrospective review and propensity-matched analysis of the Pediatric Heart Transplant Study database was performed on patients undergoing primary heart transplantation from 2004 to 2013 with at least 1 year of follow-up comparing patients treated vs not treated with sirolimus at 1 year after transplant...

Janus family kinases (JAKs) are essential molecules for cytokine responses and attractive targets for the treatment of transplant rejection and autoimmune diseases. Several JAK inhibitors have shown demonstrable effects on acute rejection in experimental cardiac transplant models. However, little is known about the potential benefits of JAK inhibitors on chronic rejection outcomes such as vasculopathy and fibrosis. Here, we examined the pharmacological profile of a novel JAK inhibitor, AS2553627, and explored its therapeutic potential in chronic rejection as well as acute rejection in a rat cardiac transplant model...
