BACKGROUND: Although contraindicated for decades, heart transplantation (HT) has finally become a feasible therapeutic option for the treatment of Chagasic patients with end-stage heart failure. Part of the success in achieving acceptable survival rates after HT is due to the enhancement of the pharmacological management of allograft rejection and reactivation of Trypanosoma cruzi infection. METHODS: By using the framework of a systematic review, we investigated if Chagasic patients who have undergone a HT are treated with similar immunosuppressive and antitrypanosomal regimens in endemic and non-endemic countries and exhibits similar T...

Changes in recipient and donor characteristics are redefining the role of induction in liver transplant recipients. Older recipients are more common, with greater concomitant comorbidity. Moderate or severe renal dysfunction is now estimated to affect 40% of liver transplant recipients. Donors are also becoming older, and other factors such as more frequent non-alcoholic fatty liver disease (NAFLD) compromise the quality of some grafts. Rejection rates are now relatively low (~10%) but some patients have a markedly increased risk such as younger recipients and those undergoing re-transplantation...

In recent years, remarkable progress has occurred in the development of technologies to support ex situ liver perfusion. Building upon extensive preclinical studies in large animal models, pilot and randomized clinical trials have been initiated, and preliminary outcomes suggest more optimal protection of both standard and extended criteria liver grafts. There currently exists an incredible opportunity and need to further refine this technology, determine appropriate viability measures to predict usable liver grafts, and to explore potent protective additive strategies to further optimize the quality of extended criteria organs...

Late allograft loss in kidney transplant recipients remains a common problem and is associated with high mortality and morbidity. The management of patients with a failed kidney allograft includes a few major dilemmas: when to start dialysis, what is the optimal management regarding immunosuppression, and should an allograft nephrectomy be performed. In suitable candidates for a repeated transplantation there are additional matters to take in consideration. In this review we will discuss these dilemmas by providing an overview of current evidence and gaps in our knowledge...

The concept of organ preservation by perfusion dates back to the mid-19th century. Innovations since then have included temperature regulation, perfusion fluid composition and various pumping systems. Advances made in liver, heart and kidney machine preservation are now contributing to increased graft utilisation, assessment of graft viability and potentially improved graft survival. Pancreas transplantation has not benefitted to the same extent from the application of perfusion technology, although the need is just as great...

Contamination of the preservation fluid (PF) used for donated organs is a potential source of post-transplant infection. However, the information on this issue is scarce. We therefore conducted a systematic review and meta-analysis to assess the incidence of culture-positive PF and its impact on solid organ transplant (SOT) recipients. Seventeen studies were identified and included. The overall incidence of culture-positive PF was 37% (95% CI: 27% to 49%), and the incidence of PF-related infections among SOT recipients with PF cultures that grew pathogenic microorganisms was 10% (95% CI: 7% to 15%)...

BACKGROUND: Active malignancies are a contraindication to transplantation, as immunosuppression can lead to worse cancer outcomes; therefore, ensuring transplant candidates are free of malignancy before transplantation is essential. This systematic review assesses the availability, quality, and consistency of recommended cancer evaluation prior to transplantation in Clinical Practice Guidelines (CPGs) for the selection of solid organ transplant candidates. METHODS: We systematically searched for CPGs for the assessment of transplant candidates...

Thrombotic microangiopathy (TMA) is a serious complication of transplantation that adversely affects kidney transplant recipient and allograft survival. Post-transplant TMA is usually classified into two categories: 1) recurrent TMA and 2) de novo TMA. Atypical hemolytic uremic syndrome (aHUS) resulting from dysregulation and over-activation of the alternate complement pathway is a rare disease but the most common diagnosis associated with recurrence in the allografts. De novo TMA, on the other hand, represents an overwhelming majority of the cases of post-transplant TMA and is a substantially more heterogeneous entity than recurrent aHUS...

Solid organ transplant (SOT) recipients are especially at risk of developing infections by multidrug resistant (MDR) Gram-negative bacilli (GNB), as they are frequently exposed to antibiotics and the healthcare setting, and are regulary subject to invasive procedures. Nevertheless, no recommendations concerning prevention and treatment are available. A panel of experts revised the available evidence; this document summarizes their recommendations: (1) it is important to characterize the isolate's phenotypic and genotypic resistance profile; (2) overall, donor colonization should not constitute a contraindication to transplantation, although active infected kidney and lung grafts should be avoided; (3) recipient colonization is associated with an increased risk of infection, but is not a contraindication to transplantation; (4) different surgical prophylaxis regimens are not recommended for patients colonized with carbapenem-resistant GNB; (5) timely detection of carriers, contact isolation precautions, hand hygiene compliance and antibiotic control policies are important preventive measures; (6) there is not sufficient data to recommend intestinal decolonization; (7) colonized lung transplant recipients could benefit from prophylactic inhaled antibiotics, specially for Pseudomonas aeruginosa; (8) colonized SOT recipients should receive an empirical treatment which includes active antibiotics, and directed therapy should be adjusted according to susceptibility study results and the severity of the infection...

REVIEW

BACKGROUND: Solid organ transplantation is an accepted treatment for end-stage solid organ diseases. During the procedure, ischemia and reperfusion injury may affect graft and patient outcomes. Remote ischemic preconditioning (rIC) has been shown to reduce ischemia and reperfusion injury and can be performed safely. Thus, rIC may potentially improve outcomes after solid organ transplantation. Traditionally, the focus of rIC has been on the donor. However, preconditioning the recipient may be a more suitable approach in transplant settings...

Although social support is used to determine transplant eligibility, the relationship between social support, medication adherence, and survival among transplant recipients remains unclear. We estimated the relationship between social support and post-transplant medication adherence and outcomes using 10 electronic databases from inception to January 2016. Study quality was assessed and all review stages were conducted independently by 2 reviewers. Systematic review and meta-analysis were conducted. Thirty-two studies (9102 participants) met inclusion criteria: 21 assessed medication adherence (5197 participants), and 13 assessed clinical outcomes (3905 participants)...

Kidney transplantation is the treatment of choice for end-stage renal disease. Despite its superiority over dialysis, the persisting organ shortage remains a major drawback. Additional sources to increase the donor pool are grafts recovered from extended criteria donors (ECD) and donation after circulatory death (DCD). Although transplantation of marginal grafts demonstrates promising outcomes, increased rates of primary non-function, delayed graft function, and reduced graft survival have been reported. Cold ischemic injury, caused by static cold storage is a significant risk factor for poor outcome...

BACKGROUND: Clinicians use several diagnostic modalities to recognize post-transplant complications, such as acute tubular necrosis, acute rejection, urologic and vascular complications. Currently, there is no consensus about the best procedural approach to evaluate post-transplant renal dysfunction. Renal needle-biopsy is often required, however, this is invasive and may lead to sample errors and complications, and most clinicians prefer using one of the noninvasive diagnostic modalities...

PURPOSE: Loop diuretics (LD) attenuate ischemic injury in nephrons. They are thought to decrease delayed graft function (DGF) during kidney transplantation (KT). This review aimed to summarize the current evidence for the perioperative use of LD during KT. METHODS: We performed an analysis of all articles that were published since the inception of Medline and Embase: 26 studies were selected for inclusion. Scope was LD use during the perioperative phase of KT only...

Renal failure and haemodialysis are associated with an increased risk of cardiovascular disease. Patients undergoing renal transplantation undergo rigorous pre-operative vascular assessment, including optimisation of risk factors for stroke. The indication for carotid intervention and the threshold for carotid endarterectomy in asymptomatic patients with incidental carotid disease has not been clarified in the context chronic kidney disease (CKD). This review aims to analyse outcomes following carotid endarterectomy in patients with CKD, in order to ascertain whether general guidelines for carotid artery revascularisation apply to this specific cohort...

BACKGROUND: Previous research has proposed that primary care interventions to increase organ donation rates can help address the discrepancy between organ donation rates and the number of patients awaiting transplant. However, no systematic review has been conducted to examine interventions in this setting. OBJECTIVE: To synthesise evidence from previous organ donation interventions conducted in a primary care setting. METHODS: Six databases and grey literature were systematically searched between November 2016 and July 2017...

Heart transplantation is still the only possible life-saving treatment for end-stage heart failure, the critical epilogue of several cardiac diseases. Epigenetic mechanisms are being intensively investigated because they could contribute to establishing innovative diagnostic and predictive biomarkers, as well as ground-breaking therapies both for heart failure and heart transplantation rejection. DNA methylation and histone modifications can modulate the innate and adaptive immune response by acting on the expression of immune-related genes that, in turn, are crucial determinants of transplantation outcome...
