Pulmonary fibrosis is a progressive, fatal manifestation of Hermansky-Pudlak syndrome (HPS). Some patients with advanced HPS pulmonary fibrosis undergo lung transplantation despite their disease-associated bleeding tendency; others die while awaiting donor organs. The objective of this study is to determine the clinical management and outcomes of a cohort with advanced HPS pulmonary fibrosis who were evaluated for lung transplantation. Six patients with HPS-1 pulmonary fibrosis were evaluated at the National Institutes of Health Clinical Center and one of two regional lung transplant centers...

PURPOSE: Using a rat model of allograft lung transplantation, we investigated the effectiveness of mesenchymal stromal cells (MSCs) as prophylactic and therapeutic agents against the acute rejection of lung grafts. METHODS: Lung grafts were harvested from donor rats and transplanted orthotopically into major histocompatibility complex-mismatched rats. MSCs were administered to the recipients once (on day 0) or twice (on days 0 and 3) after transplantation. The grade of acute rejection was evaluated both macroscopically and microscopically 6 days after transplantation...

Right ventricular (RV) hypertrophy is regarded as the adaptation on chronic RV pressure load in pulmonary hypertension. As the RV Sokolow-Lyon index (RVSLI) is an electrocardiographic marker of RV hypertrophy, we hypothesized that RVSLI might be able to reflect RV pressure load. Therefore, the purpose of this study was to characterize the diagnostic impact of the RVSLI in children with idiopathic pulmonary arterial hypertension (IPAH) in order to assess disease severity and to evaluate its value for the prediction of worse outcome...

Background: Respiratory virus infection (RVI) in pediatric solid organ transplant (SOT) recipients poses a significant risk; however, the epidemiology and effects of an RVI after pediatric SOT in the era of current molecular diagnostic assays are unclear. Methods: A retrospective observational cohort of pediatric SOT recipients (January 2010 to June 2013) was assembled from 9 US pediatric transplant centers. Charts were reviewed for RVI events associated with hospitalization within 1 year after the transplant...

OBJECTIVES: To evaluate the impact of Burkholderia cepacia complex colonization in cystic fibrosis patients undergoing lung transplantation. METHODS: We prospectively analyzed clinical data and respiratory tract samples (sputum and bronchoalveolar lavage) collected from suppurative lung disease patients between January 2008 and November 2013. We also subtyped different Burkholderia cepacia complex genotypes via DNA sequencing using primers against the recA gene in samples collected between January 2012 and November 2013...

There has recently been considerable progress in the results of pig organ transplantation in nonhuman primates (NHPs), largely associated with the availability of (i) pigs genetically-engineered to overcome coagulation dysregulation, and (ii) novel immunosuppressive agents. The barriers of thrombotic microangiopathy and/or consumptive coagulation were believed to be associated with (i) activation of the graft vascular endothelial cells (VECs) by a low level of anti-pig antibody binding and/or complement deposition and/or innate immune cell activity, and (ii) molecular incompatibilities between the NHP and pig coagulation-anticoagulation systems...

Complement-mediated allograft injury, elicited by donor specific HLA antibodies (DSA), is a defining pathophysiological characteristic of allograft damage. We aimed to study DSA-induced complement activation as a diagnostic marker of antibody mediated rejection (AMR) and a risk stratification tool for graft loss in the context of lung transplantation (LT). We identified 38 DSA positive patients whose serum samples were submitted for C3d deposition testing via the C3d assay. Among these 38 patients, 15 had AMR (DSAP os AMRP os )...

INTRODUCTION: Lung disease is the major cause of death among cystic fibrosis (CF) patients, affecting 80% of the population. The impact of extracorporeal circulation (ECC) during transplantation has not been fully clarified. This study aimed to evaluate the outcomes of lung transplantation for CF in a single center, and to assess the impact of ECC on survival. METHODS: We performed a retrospective observational study of all trasplanted CF patients in a single center between 1992 and 2011...

BACKGROUND: Depressive symptoms are common among lung transplant recipients and have been associated with worse clinical outcomes. However, few studies have examined the association between depressive symptoms assessed at multiple time points or behavioral mechanisms by which post-transplant depressive symptoms may confer greater clinical risk. We therefore examined the associations between depressive symptoms, exercise capacity, chronic lung allograft dysfunction (CLAD), and mortality prospectively in a large sample of lung transplant recipients...

The aim of the present study was topreliminarily visualize the distribution of humanumbilical cord‑derivedmesenchymal stem cells (hUC‑MSCs) in treating acute lung injury (ALI) using a targeted fluorescent technique. Anovel fluorescent molecule probe was first synthesized via the specific binding of antigen and antibody in vitro to label the hUC‑MSCs. Two groups of mice, comprising a normal saline (NS)+MSC group and lipopolysaccharide (LPS)+MSC group, were subjected to optical imaging. At 4 h following ALI mouse model construction, the labeled hUC‑MSCs were transplanted into the mice in the NS+MSC group and LPS+MSC group by tail vein injection...

Introduction: Idiopathic pulmonary fibrosis (IPF), a progressive life-limiting lung disease affects approximately 128 000 newly diagnosed individuals in the USA annually. IPF, a disease of ageing associated with intense medical and financial burden, is expected to grow in incidence globally. Median survival from diagnosis is 3.8 years, and many of these patients succumb to a rapid death within 6 months. Despite the fatal prognosis, we have found that patients and caregivers often fail to understand the poor prognosis as the disease relentlessly progresses...

We present a case of young female patient with end stage lung failure due to pulmonary arterial hypertension who was failing maximal medical therapy and was listed for a single sequential lung transplantation. The challenge of the case was a concomitant presence of a large atrial septal defect (ASD). The novelty of our approach was a device closure of ASD before performing a transplant with the use of intraoperative venoarterial extracorporeal membrane oxygenation (ECMO).

BACKGROUND: Previous studies have suggested that antibodies against human leukocyte antigen (HLA) are associated with worse outcomes in lung transplantation. However, little is known about the factors associated with outcomes following lung transplantation in Asia. Accordingly, we investigated the prevalence of anti-HLA antibodies in recipients before transplantation and assessed their impact on outcomes in Korea. METHODS: A single-center retrospective study was conducted...

Massive hemoptysis occurs in a minority of patients with cystic fibrosis, with an annual incidence of 1%. Although rare, massive hemoptysis can be a severe and potentially fatal complication of this disease. Beyond the acute life-threatening event, hemoptysis in patients with cystic fibrosis has been associated with faster decline in lung function, accelerated need for lung transplant, and increased mortality. The bronchial arteries are the culprit vessels in over 90% of cases of hemoptysis. This normally quiescent vascular system undergoes remarkable hypertrophy, collateralization, and angiogenesis before the onset of hemoptysis, introducing numerous pitfalls for the interventionalist...

BACKGROUND AND PURPOSE: Physiotherapy "standard care" for the acute post lung transplant recipient has not yet been documented. We aimed to analyse how soon patients commence exercise and how much time is dedicated to this during physiotherapy sessions acutely post lung transplantation. METHODS: Prospective observational study of bilateral sequential and single lung transplant recipients for any indication, ≥18 years. Participants were observed during 6 physiotherapy sessions: 3 initial and 3 prior to acute inpatient discharge...

Cystic fibrosis (CF) with severe lung disease is a well-recognized indication for lung transplantation. Colonization with various organisms in CF patients may impact post-transplant morbidity and mortality. Burkholderia cepacia complex (BCC) is made up of distinct genomovars with significant morbidity and mortality associated with B. cenocepacia (genomovar III) following lung transplant. The outcomes of patients infected with genomovar B. dolosa (genomovar VI) have yet to be described in the literature. We performed a retrospective chart review of all cystic fibrosis patients colonized with B...

OBJECTIVES: Extracorporeal membrane oxygenation (ECMO) has become the standard of cardiopulmonary support during a sequential double lung transplant for pulmonary hypertension. Whether central or peripheral cannulation is the best strategy for these patients remains unknown. Our goal was to determine which is the best strategy by comparing 2 populations of patients. METHODS: We performed a single-centre retrospective study based on an institutional prospective lung transplant database...

OBJECTIVES: Despite improved success with solid-organ transplant procedures, recipients remain at risk for infections, including pneumonia, due to their immunosuppressive regimens. In solid-organ transplant patients, clinical findings of pneumonia can be nonspecific, and diagnosis of pneumonia may be difficult as several conditions (drug lung, hypervolemia, infections, hemorrhage) can led to pulmonary infiltrates, mimicking pneumonia in these patients. The role of mean platelet volume, a predictor of inflammatory disease, with elevated values inversely correlated with inflammatory problems, in the diagnosis of pneumonia has not yet been investigated in solid-organ transplant patients...

Hydrothorax occurs frequently in patients with endstage liver disease and usually requires drainage of pulmonary effusion during the hepatectomy phase of liver transplant. Reexpansion pulmonary edema is a rare but potentially fatal complication seen after rapid reexpansion of the collapsed lung following thoracentesis of pleural fluid or tube drainage of pneumothorax. This condition, which manifests with various degrees of clinical severity, is rarely reported following liver transplantation. Herein, we present a 62-year-old male patient who developed reexpansion pulmonary edema after drainage of massive pleural effusion, which caused a total collapse in the right hemithorax during liver transplant...
