BACKGROUND: Graft-derived cell-free DNA (GcfDNA), which is released into the blood stream by necrotic and apoptotic cells, is a promising noninvasive organ integrity biomarker. In liver transplantation (LTx), neither conventional liver function tests (LTFs) nor immunosuppressive drug monitoring are very effective for rejection monitoring. We therefore hypothesized that the quantitative measurement of donor-derived cell-free DNA (cfDNA) would have independent value for the assessment of graft integrity, including damage from acute rejection...

In most countries, patients with lungs destroyed by tuberculosis (TB) are excluded from lung transplantation (LTx) because of concerns about TB recurrence. LTx may be an effective therapeutic option for patients with chronic respiratory failure, but there are no reports of successful LTx in patients with lungs destroyed by TB. We present the case of successful single LTx in a patient with chronic respiratory failure after pneumonectomy with antituberculous chemotherapy. At the 16-month follow-up, he did not show any evidence of TB recurrence and his respiratory problems and quality of life were improved by LTx...

INTRODUCTION: Little data exists regarding optimal therapeutic strategies post-operatively after lung transplant (LTx). Current practice patterns rely on expert opinion and institutional experience resulting in non-uniform post-operative care. To better define current practice patterns, an international survey of LTx clinicians was conducted. METHODS: A 30-question survey was sent to transplant clinicians via email to the ISHLT open forum mailing list and directly to the chief transplant surgeon and pulmonologist of all LTx centers in the United States...

BACKGROUND: Neurological disorders due to calcineurin inhibitor (CNI) treatment pose a well-known problem after liver transplantation (LTx). In this study, the impact of CNIs on cognitive functioning during maintenance therapy was analyzed. A possible improvement of cognitive functioning, compliance and health-related quality of life (HRQoL) after conversion to a once-daily tacrolimus formulation was prospectively assessed. METHODS: In a cross-section analysis cognitive functioning of living donors (LD), waiting list patients and LTx patients was tested using a 4 times trail making test (4-TTMT)...

Low muscle mass is common in lung transplant (LTx) candidates, however, the clinical implications have not been well described. The study aims were to compare skeletal muscle mass in LTx candidates with controls using thoracic muscle cross-sectional area (CSA) from computed tomography and assess the association with pre- and post-transplant clinical outcomes. This was a retrospective, single centre cohort study of 527 LTx candidates (median age: 55 IQR [42-62] years; 54% male). Thoracic muscle CSA was compared to an age-and sex-matched control group...

Post-transplant lymphoproliferative disorder (PTLD) may compromise long-term outcome of lung transplant (LTx) recipients. A case-control study was performed, comparing LTx recipients with PTLD (n=31) to matched recipients without PTLD (Controls, n=62). Risk factors for PTLD and post-transplant outcomes were assessed. PTLD prevalence was 3.9%, time to PTLD 323 (166-1132) days; and 54.8% had early-onset PTLD versus 45.2% late-onset PTLD. At LTx, more Epstein-Barr virus (EBV)-seronegative patients were present in PTLD (42%) compared to Controls (5%) (p<0...

BACKGROUND: The allocation of donor lungs for transplantation in Germany was changed on 10 December 2011 to a system based on the Lung Allocation Score (LAS). The aim of the present study is to determine whether this change has prolonged the survival of patients on the transplant waiting list and of those who have undergone lung transplantation (LTx). METHODS: We retrospectively compared data from the three-year periods before and after the change to an LAS-based allocation system (2009-2011 vs...

Antibodies against HLA and non-HLA are associated with transplantation outcome. Recently, pretransplant serum IgG antibody levels against apoptotic cells were found to correlate with kidney allograft loss. We investigated the presence of these antibodies in lung transplantation (LTx) patients and evaluated the correlation of pre-LTx serum levels of IgG antibodies against apoptotic cells with LTx outcome. These cells included donor lung endothelial cells (ECs) obtained from lung perfusion fluid collected during LTx procedure...

BACKGROUND: Lung transplantation (LTx) is offered to older and more complex patients who may be at higher risk of skeletal muscle dysfunction, but the clinical implications of this remain uncertain. The study aims were to characterize deficits in skeletal muscle mass, strength and physical performance and examine the associations of these deficits with clinical outcomes. METHODS: Fifty LTx candidates (58% male, 59 ± 9 years) were prospectively evaluated for skeletal muscle deficits: muscle mass using bio-electrical impedance, quadriceps, respiratory muscle and handgrip strength, and physical performance with the Short Physical Performance Battery...

Fabíola Villac Adde, Sílvia Vidal Campos, Ricardo Henrique de Oliveira Braga Teixeira, Joaquim Carlos Rodrigues
The current available literature evaluating lung resection surgery and lung transplantation in children with cystic fibrosis (CF) was reviewed through a PubMed search and references from selected studies were additionally included. Pulmonary resections, i.e. lobectomy, segmentectomy, and pneumonectomy, are seldom performed in CF. The main indications, in patients with a forced expiratory volume in 1second (FEV1) that is greater than 30% predicted, are localized bronchiectasis/atelectasis, severe hemoptysis, and bronchopleural fistula refractory to medical management...

Surgical site infections (SSIs) are infections of tissues, organs, or spaces exposed by surgeons during performance of an invasive procedure. SSIs are classified into superficial, which are limited to skin and subcutaneous tissues, and deep. The incidence of deep SSIs in lung transplant (LTx) patients is estimated at 5%. No reports have been published as to the incidence of superficial SSIs specifically in LTx patients. Common sense would dictate that the majority of superficial SSIs would be bacterial. Uncommonly, fungal SSIs may occur, and we believe that no reports exist as to the incidence of viral wound infections in LTx patients, or in any solid organ transplant patients...

BACKGROUND: The incidence of liver disease is increasing in USA. Animal models had shown glutathione species in plasma reflects liver glutathione state and it could be a surrogate for the detection of hepatocellular carcinoma (HCC). METHODS: The present study aimed to translate methods to the human and to explore the role of glutathione/metabolic prints in the progression of liver dysfunction and in the detection of HCC. Treated plasma from healthy subjects (n = 20), patients with liver disease (ESLD, n = 99) and patients after transplantation (LTx, n = 7) were analyzed by GC- or LC/MS...

BACKGROUND: The heterogeneous progression of idiopathic pulmonary fibrosis (IPF) makes prognostication difficult and contributes to high mortality on the waitlist for lung transplantation (LTx). Multi-dimensional scores (Composite Physiologic index [CPI], [Gender-Age-Physiology [GAP]; RIsk Stratification scorE [RISE]) demonstrated enhanced predictive power towards outcome in IPF. The lung allocation score (LAS) is a multi-dimensional tool commonly used to stratify patients assessed for LTx...

BACKGROUND: Acute kidney injury (AKI) is a common complication in the early period of lung transplantation (LTx). We aimed to describe the incidence and perioperative risk factors associated with AKI following LTx. METHODS: Clinical data of 30 patients who underwent LTx were retrospectively reviewed. Primary outcomes were development of AKI and patient mortality within 30 postoperative days. Postoperative AKI is determined based on creatinine criteria from Acute Kidney Injury Network (AKIN) classification...

OBJECTIVES: Pulmonary arterial hypertension (PAH) is a progressive and often fatal disease characterized by increased pulmonary vascular resistance (PVR) and right ventricular (RV) failure. End-stage PAH is often an indication for a lung transplant (LTX). Our goal was to study ventricular recovery using cardiac magnetic resonance imaging late after LTX. METHODS: We studied 10 patients with PAH who underwent isolated bilateral LTX. RV and left ventricular (LV) volumes, function and mass were measured...

Respiratory diseases represent a major healthcare burden worldwide. Lung transplantation (LTx) is the gold-standard for end-stage patients, strongly limited by shortage of available/suitable donor lungs. Normothermic ex vivo lung perfusion (EVLP) has significantly increased the number of lungs suitable for transplantation. Steen solution is used for EVLP, but the mechanisms involved in its beneficial properties remain to be clarified. We investigated the effects of Steen solution in an in vitro protocol of cold starvation and normothermic recovery (CS/NR) on human lung spheroids, named pneumospheres (PSs), containing epithelial/basal cells, and on endothelial HUVEC cells...

BACKGROUND: Recipient adolescent age for non-lung solid-organ transplantation is associated with higher rates of rejection, graft loss and mortality. Although there have been no studies specifically examining adolescent outcomes after lung transplantation (LTx), limited data from the International Society of Heart and Lung Transplantation (ISHLT) Registry suggest that a similar association may exist. Recently, adolescence has been defined as 10 to 24 years of age, taking into account the biologic and sociologic transitions that occur during this age interval...

BACKGROUND: Idiopathic hyperammonemia syndrome (IHS) is an uncommon, often deadly complication of solid organ transplantation. IHS cases in solid organ transplantation seem to occur predominantly in lung transplant (LTx) recipients. However to the best of our knowledge the occurrence of IHS has not been systematically evaluated. We set out to identify all reported cases of IHS following non-liver solid organ transplantations. METHODS: Retrospective review of our institutional experience and systematic review of the literature...
