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...

Lei Huang, Ming Ji, Shounan Yi, Xinmin Zhou
Heart-lung transplant is the most effective therapy for patients with end-stage cardiopulmonary disease. Here, we report an initial assessment of a 31-year-old man who had survived more than 11 years after heart-lung transplant, which represents the longest survival time in this procedure in Asian studies. At his 11th anniversary after transplant, extensive tests were carried out, especially to detect regulatory T-cell levels for the first time in a surviving heart-lung transplant recipient. Preliminarily data revealed the status of his immunologic function in relation to chronic allograft rejection...

Objective: To explore the function of NLRP1 in noninfectious pulmonary injury (nonIPI) after allogeneic stem cell transplantation (allo-HSCT) . Methods: In this study, we established the model of allo-HSCT with C57BL/6 and NLRP(-/-) mouse as recipients. Chimera rate was measured by flow cytometry. The HE staining was used to observe the pathology changes in the lungs. NLRP1 and relevant inflammatory proteins were measured by Western Blot. Results: On the day 14 after allo-HSCT, the chimera rate was more than 96%, HSCs of donors had been successfully transplanted into recipients...

The Sydney Heart Bank (SHB) is one of the largest human heart tissue banks in existence. Its mission is to provide high-quality human heart tissue for research into the molecular basis of human heart failure by working collaboratively with experts in this field. We argue that, by comparing tissues from failing human hearts with age-matched non-failing healthy donor hearts, the results will be more relevant than research using animal models, particularly if their physiology is very different from humans. Tissue from heart surgery must generally be used soon after collection or it significantly deteriorates...

Primary central nervous system lymphoma (PCNSL) risk is greatly increased in immunosuppressed HIV-infected people. Using data from the United States transplant registry linked with 17 cancer registries (1987-2014), we studied PCNSL and systemic non-Hodgkin lymphoma (NHL) in 288,029 solid organ transplant recipients. Transplant recipients had elevated incidence for PCNSL compared with the general population (standardized incidence ratio=65.1; N=168), and this elevation was stronger than for systemic NHL (standardized incidence ratio=11...

BACKGROUND: It is standard practice to administer prophylactic antibiotics post lung transplantation. However, no studies have evaluated the impact of culture positivity. The purpose of this study was to evaluate early post-transplant outcomes of culture-positive and culture-negative lung transplant (LT) recipients and the appropriateness of the empiric regimens used. METHODS: Adult patients who received an LT at Emory University Hospital between January 1, 2010 and August 31, 2015 were reviewed and stratified into three groups: (i) culture-positive appropriate empiric treatment, (ii) culture-positive inappropriate empiric treatment, and (iii) culture-negative...

Hemodynamic instability is generally considered as a contraindication to liver splitting, in particular when using an in-situ technique. We describe the cases of two young donors with brain death in whom refractory cardiac arrest and hemodynamic instability were supported by veno-arterial extracorporeal membrane oxygenation (VA-ECMO), allowing uneventful in situ splitting. Two adult and two pediatric liver recipients were successfully transplanted with immediate graft function. Favorable outcomes were also observed for the other transplanted organs, including one heart, two lungs and four kidneys...

BACKGROUND: Venous thromboembolism (VTE) is a frequent complication after solid organ transplantation (SOT) and, specifically, after lung transplantation (LT). The objectives of this study were to evaluate prophylaxis with enoxaparin and to describe risk factors for VTE after LT. METHODS: We retrospectively reviewed the clinical records of 333 patients who underwent LT in our institution between 2009 and 2014. We compared 2 consecutive cohorts, one that received enoxaparin only during post-transplant hospital admissions and a second cohort that received 90-day extended prophylaxis with enoxaparin...

Tumor hypoxia is a major cause of treatment failure for a variety of malignancies. However, hypoxia also leads to treatment opportunities as demonstrated by the development of compounds that target regions of hypoxia within tumors. Evofosfamide is a hypoxia-activated prodrug that is created by linking the hypoxia-seeking 2-nitroimidazole moiety to the cytotoxic bromo-isophosphoramide mustard (Br-IPM). When evofosfamide is delivered to hypoxic regions of tumors, the DNA cross-linking toxin, Br-IPM, is released leading to cell death...

BACKGROUND Although administration of tacrolimus, whether by the enteric, sublingual, or continuous intravenous routes, has some limitations, twice-daily bolus intravenous tacrolimus administration has been shown to be beneficial in optimizing efficacy and safety after lung transplantation. However, at present, the duration of bolus intravenous tacrolimus administration is limited, and the effects of prolonged bolus intravenous tacrolimus administration remain unknown. Our study was aimed at assessing the safety and efficacy of prolonged twice-daily bolus intravenous tacrolimus administration in the early phase after lung transplantation...

REVIEW
Henri Roukoz, David G Benditt
Atrial arrhythmias are a common complication after lung transplant (LT), occurring in about 16-46% of LT patients early postoperatively, and in about 14% during longer-term follow-up. They have a significant impact on postoperative in-hospital length of stay and may have an impact on overall mortality. In this report, we review the incidence and risk factors of post lung transplant AA, their pathogenesis and their impact on short- and long-term outcomes. Pharmacological management options are reviewed. In brief, early atrial arrhythmias tend to be mostly atrial fibrillation and are treated acutely with a rate control strategy followed if needed by rhythm control for 4-6 weeks...

REVIEW
Cassie C Kennedy, Raymund R Razonable
Infection remains a significant source of morbidity and mortality after lung transplant, including fungal infection. Various antifungal prophylactic agents are administered for a variable duration after transplant with the goal of preventing invasive fungal infections. Alternatively, some programs target the use of antifungal agents only in those colonized with Aspergillus spp. Despite prophylaxis or preemptive therapy, a significant number of invasive fungal infections occur after lung transplant. Risk factors for fungal infections include single lung transplant, pretransplant Aspergillus colonization, environmental risks, structural lung disease such as cystic fibrosis, augmented immunosuppression, sinus disease, and use of indwelling airway stents...

A 58-year-old man with idiopathic pulmonary fibrosis, who had received a right-sided single-lung transplant 2 years earlier, was referred to the sleep clinic for the assessment of nocturnal position-dependent episodes of dyspnea and frequent arousals when lying on his right side. There was no subjective worsening of daytime respiratory symptoms, but he complained of fatigue and unrefreshing sleep. His Epworth Sleepiness Scale score was 12/24. After lung transplantation he had a favorable course while receiving immunosuppression with prednisolone, everolimus, and mycophenolate mofetil...

BACKGROUND: Nijmegen breakage syndrome (NBS) is a combined primary immunodeficiency with DNA repair defect, microcephaly, and other phenotypical features. It predominantly occurs in Slavic populations that have a high frequency of carriers with the causative NBN gene c.657_661del5 mutation. Due to the rarity of the disease in the rest of the world, studies of NBS patients are few. Here, we report a prospective study of a cohort of Russian NBS patients. METHODS: 35 Russian NBS patients of ages 1-19 years, referred to our Center between years 2012 and 2016, were prospectively studied...

Lung transplantation is a viable treatment option for patients with end-stage lung diseases such as interstitial pneumonia/pulmonary fibrosis, emphysema, pulmonary hypertension, and so on. Collecting available clinical, physiological, serological, and surgical information of both donor and recipient is vital when planning relevant postoperative managements. The goal of the managements is to keep the transplanted lung (s) functional while preventing/treating infection, rejection, and ischemiareperfusion lung injury...

BACKGROUND: Cardiac allograft vasculopathy (CAV) remains a leading cause of morbidity and mortality after orthotopic heart transplantation (OHT). Little is known about the influence of aspirin on clinical expression of CAV. METHODS: We followed 120 patients with OHT at a single center for a median of 7 years and categorized them by the presence or absence of early aspirin therapy post-transplant (aspirin treatment ≥6 months in the first year). The association between aspirin use and time to the primary end-point of angiographic moderate or severe CAV (International Society for Heart and Lung Transplantation grade ≥2) was investigated...
