BACKGROUND: Extracorporeal membrane oxygenation is a resource-intensive mode of life-support potentially applicable when conventional therapies fail. Given the initial success of extracorporeal membrane oxygenation to support neonates and infants in the 1980s, indications have expanded to include adolescents, adults, and selected moribund patients during cardiopulmonary resuscitation. This single-institution analysis was conducted to evaluate programmatic growth, outcomes, and risk for death despite extracorporeal membrane oxygenation across all ages and diseases...

BACKGROUND: Extended criteria donor lungs deemed unsuitable for immediate transplantation can be reconditioned using ex vivo lung perfusion (EVLP). Objective identification of which donor lungs can be successfully reconditioned and will function well post-operatively has not been established. This study assessed the predictive value of markers of inflammation and tissue injury in donor lungs undergoing EVLP as part of the DEVELOP-UK study. METHODS: Longitudinal samples of perfusate, bronchoalveolar lavage, and tissue from 42 human donor lungs undergoing clinical EVLP assessments were analyzed for markers of inflammation and tissue injury...

OBJECTIVE: The M2 phenotype is dominant in tumor associated macrophages (TAM), and plays a key role in promoting tumor growth, invasion and metastasis. Converting TAM polarization from M2 to M1 may contribute to eliciting anti-tumor-specific immune responses and inhibiting tumor metastasis. In this study, the effect of reversing the polarization of TAM on tumor metastasis was investigated. METHODS: Peritoneal macrophages were obtained from BABL/c mice, and M2 polarization was induced by IL-4...

BACKGROUND: No satisfactory treatment exists for chronic rejection (CR) after lung transplantation (LT). Our objective was to assess whether ozone (O3) treatment could ameliorate CR. METHODS: Male Sprague-Dawley inbred rats (n = 36) were randomly assigned into four groups: (1) control (n = 6), (2) sham (n = 6), (3) LT (n = 12), and (4) O3-LT (n = 12). Animals underwent left LT. O3 was rectally administered daily for 2 weeks before LT (from 20 to 50 μg) and 3 times/wk (50 μg/dose) up to 3 months...

Cystic fibrosis (CF) affects multiple organs including the lung, liver, and pancreas. Lung transplant, liver transplant, and combined lung-liver transplant have become well-established therapies for CF patients with end-stage organ failure. Thus far, however, there has been limited experience with pancreas transplantation in CF. In this report, we detail the clinical history, transplant procedure, and post-operative recovery of a patient who underwent combined lung-liver-pancreas transplant for advanced CF.

Cystic fibrosis (CF) is a common indication for lung transplantation (LTx) in children and adults with severe and irreversible lung disease. In the setting of LTx in the CF population, immunosuppressive medications are used to prevent allograft rejection despite the majority of these patients being chronically infected with numerous, and often antibiotic-resistant, pathogens. There is limited evidence for the optimal post-LTx immunosuppression regimen in patients with CF, particularly in children. This article provides a review of immunosuppression regimens in the pediatric and adult CF post-LTx population, investigating drug dosing and monitoring, and medication combinations...

The present study tests a hypothesis that cardioprotective effects mediated by autologous adipose-derived stem cells (ADSC) in rats afflicted with insulin-dependent diabetes mellitus (IDDM), may be synergistically enhanced by oral treatment with green tea epigallocatechin gallat (ECCG). Wistar rats were divided into sham, DM, DM+ADSC (autologous transplanted 1x106 cells/rat) and DM+ADSC+E (E, green tea oral administration EGCG). Heart tissues were isolated for all rats and investigations were performed after 2-months treatment...

Pediatric lung transplant is a viable option for treatment of end-stage lung disease in children, with > 100 pediatric lung transplants reported to the Registry of the International Society of Heart and Lung Transplantation each year. Long-term success is limited by availability of donor organs, debilitation as a result of chronic disease, impaired mucus clearance resulting from both surgical and pharmacologic interventions, increased risk for infection resulting from immunosuppression, and most importantly late complications, such as chronic lung allograft dysfunction...

John C Lin
Extracorporeal membrane oxygenation (ECMO) was developed initially in the 1960s to support refractory respiratory failure in addition to the cardiac support inherent in a venoarterial bypass circuit. Early successes occurred predominantly in the neonatal population with subsequent randomized controlled trials and comprehensive reviews concluding therapeutic efficacy for ECMO in neonatal respiratory failure. In contrast, the evidence supporting ECMO for respiratory failure in children is less definitive. However, although pediatric randomized controlled trials have not been completed, sufficient evidence in support of ECMO as a beneficial therapy for pediatric respiratory failure exists...

BACKGROUND: Lung transplantation is the only effective treatment for end-stage lung diseases. Bronchiolitis obliterans, which is known as non-infectious chronic lung allograft dysfunction (CLAD) in the new classification, is the greatest threat to long-term survival after lung transplantation. This study investigated the role of leukotriene B4 (LTB4) and montelukast in transplantation-related bronchiolitis obliterans and discussed the pathophysiological significance of LTB4 in chronic rejection...

BACKGROUND: Lung transplant patients are a vulnerable group of immunosuppressed patients that are prone to frequent respiratory infections. We studied 60 episodes of respiratory symptoms in 71 lung transplant patients. Almost half of these episodes were of unknown infectious etiology despite extensive routine diagnostic testing. METHODS: We re-analyzed respiratory samples of all episodes with undetermined etiology in order to detect potential viral pathogens missed/not accounted for in routine diagnostics...

A 53-year-old woman who underwent bilateral lung transplantation 14 months before presented with 2 to 3 weeks of severe exertional dyspnea. Workup revealed a complete embolic occlusion of her left main pulmonary artery related to a femoral deep venous thrombosis. The occlusion did not respond to systemic anticoagulation, and a trial of catheter-directed thrombolysis was pursued. Flow to the left lower lobe was restored after 2 days of thromobolytic therapy. The patient is alive and well at more than 1 year of follow-up...

PURPOSE OF REVIEW: BK virus is a significant risk factor for kidney allograft dysfunction and loss among renal transplant recipients. Currently, there is no proven effective treatment except for the reduction of immunosuppression. In this review, we discuss diagnostic challenges and current treatment options for BK in kidney transplant recipients. RECENT FINDINGS: Antiviral and antibiotic therapies have been employed for BK viraemia with variable efficacy. In addition, novel therapeutic regimens such as adoptive transfer of targeted T cells have been described as possible treatment options for recipients with BK nephropathy...
