Transplant-related complications are common after allogeneic hematopoietic stem cell transplantation (allo-HSCT), including graft versus host disease (GVHD). The lungs are frequently affected during the course of allo-HSCT, and among the non-infectious pulmonary complications bronchiolitis obliterans syndrome (BOS) is the most common and considered the only diagnostic manifestation of pulmonary GVHD. BOS is an irreversible obstructive disease that affects the terminal bronchioles, and it is associated with high morbidity and mortality rates...

INTRODUCTION: Over 27,000 circumcisions were performed in England in 2012-13. The complication rate is generally perceived to be low, although published figures vary widely. Balanitis xerotica obliterans, more correctly termed Lichen Sclerosus et atrophicus (LS), is one of the commonest indications for medical circumcision. To test the hypothesis that children undergoing circumcision for LS have a higher rate of postoperative bleeding than those undergoing the procedure for other reasons, we retrospectively reviewed records for patients undergoing circumcision...

BACKGROUND: Lung retransplantation (ReTx) comprises an increasing share of lung transplants and recently has shown improved outcomes. The aim of this study was to identify risk factors affecting overall survival after pulmonary ReTx. METHODS: The United Network for Organ Sharing database was used to identify patients undergoing lung transplantation at our institution from 1995 to 2014. Of the total 542 lung transplants performed, 87 (16.1%) were ReTxs. The primary outcome was overall survival...

In long-term survivors of allogeneic hematopoietic cell transplantation (HCT), chronic graft-versus-host disease (GVHD) is the major cause of morbidity and mortality and a major determinant of quality of life. Chronic GVHD responds poorly to current immunosuppressive drugs, and while T-cell depletion may be preventative, this gain is offset by increased relapse rates. A significant impediment to progress in treating chronic GVHD has been the limitations of existing animal models. The goal of this study was to develop a reproducible, comprehensive model of chronic GVHD in the dog...

The pathogenesis of bulla formation has not yet been demonstrated in pathologic examinations or through direct visualization during thoracotomy or thoracoscopic surgery. We present two cases of giant bulla formation after pneumothorax because of cryptogenic organizing pneumonia and lung abscess. The case findings suggested that the pathogenesis was attributable to a check-valve mechanism, secondary to bronchiolitis obliterans, or the presence of an obstructing air leakage due to a lung fistula. The lung fistula had been covered by inflammatory membranes consisting of blood and/or fibrous precipitates with detached visceral pleura...

Interstitial lung disease is a well-known pulmonary adverse event that occurs during epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy and results in restrictive ventilatory dysfunction. However, obstructive changes such as those associated with bronchiolitis obliterans (BO) have never been reported as adverse events resulting from the use of any approved EGFR-TKI. This report documents an autopsy case of BO that developed during afatinib treatment for adenocarcinoma of the lung...

Refractory acute-cellular rejection (rACR) is associated with death and bronchiolitis obliterans syndrome (BOS) post-lung transplantation. We report the largest cohort of lung transplant recipients (LTR) treated with rescue alemtuzumab for rACR or BOS. RACR outcomes included burden of ACR 30-days before and 180-days after rescue assessed by a novel composite rejection standardized score (CRSS, range 0-6); freedom from ≥A2 ACR. BOS outcomes included freedom from BOS progression and FEV1 decline >10%. Univariate parametric and nonparametric statistical approaches were used to assess treatment response...

The long-term success of lung transplantation (LT) is limited by chronic lung allograft dysfunction (CLAD). Different phenotypes of CLAD have been described, such as bronchiolitis obliterans syndrome (BOS) and restrictive allograft syndrome (RAS). The purpose of this study was to investigate levels of cytokines and chemokines in bronchoalveolar lavage fluid (BALF) as markers of these CLAD phenotypes. BALF was collected from 51 recipients who underwent (bilateral and unilateral) LT. The study population was divided into three groups: stable (ST), BOS, and RAS...

Occlusion of the bronchial orifices by tissue-like structures is an uncommonly reported finding: it has been referred to as bronchial webs, bronchial synechiae, vanishing bronchus syndrome, or membranous obliterative bronchitis. It differs from bronchiolitis obliterans, a well-described clinical entity that involves smaller airways not visualized on bronchoscopy. Although initially only recognized as a congenital condition, later reports have described it in situations where chronic inflammation results in the irritation of the airways...

Chronic lung allograft dysfunction (CLAD) is the major limitation of long-term survival after lung transplantation (LT). CLAD manifests as Bronchiolitis Obliterans Syndrome (BOS) or Restrictive Allograft Syndrome (RAS). Alloimmune reactions and epithelial-to-mesenchymal transition have been suggested in BOS. However, little is known regarding the role of allogenicity on epithelial cell differentiation. Primary human bronchial epithelial cells (BEC) were treated with activated T cells in the presence or absence of TGF-β...

Occupational exposures to the diketone flavoring agent, diacetyl, have been associated with bronchiolitis obliterans, a rare condition of airway fibrosis. Model studies in rodents have suggested that the airway epithelium is a major site of diacetyl toxicity, but the effects of diacetyl exposure upon the human airway epithelium are poorly characterized. Here we performed quantitative LC-MS/MS-based proteomics to study the effects of repeated diacetyl vapor exposures on 3D organotypic cultures of human primary tracheobronchial epithelial cells...

Maladaptive epithelial repair from chronic injury is a common feature in fibrotic diseases, which in turn activates a pathogenic fibroblast response that produces excessive matrix deposition. Dysregulated microRNAs (miRs) can regulate expression of multiple genes and fundamentally alter cellular phenotypes during fibrosis. Although several miRs have been shown to be associated with lung fibrosis, the mechanisms by which miRs modulate epithelial behavior in lung fibrosis are lacking. Here, we identified miR-323a-3p to be downregulated in the epithelium of lungs with bronchiolitis obliterans syndrome (BOS) after lung transplantation, idiopathic pulmonary fibrosis (IPF), and murine bleomycin-induced fibrosis...

BACKGROUND: Acute rejection (AR) and development of chronic rejection, bronchiolitis obliterans syndrome (BOS), remain major limiting factors for lung transplantation (LTx). This retrospective study is to identify differentially expressed circulating microRNAs (miRNAs) that associate with development of AR and BOS in pediatric lung transplant recipients (LTxR). METHODS: We determined the circulating levels of 7 selected candidate miRNAs in 14 LTxR with AR, 7 with BOS, and compared them against 13 stable pediatric LTxR at 1, 6, and 12 months following LTx...

Microvascular loss may be a root cause of chronic rejection in lung transplants, which leads to the bronchiolitis obliterans syndrome. Previous research implicates T regulatory cell (Treg) as a key component of immune modulation, however, Treg has never been examined as a reparative mediator to salvage microvasculature during transplantation. Here, we reconstituted purified Tregs in to allografts, and serially monitored allografts for tissue oxygenation, microvascular perfusion for four weeks. We demonstrated that Tregs reconstitution of allografts significantly improve tissue oxygenation, microvascular flow, epithelial repair, number of CD4(+)CD25(high)FOXP3(+) Tregs, followed by an upregulation of proinflammatory, angiogenic and regulatory genes, while prevented subepithelial deposition of CD4(+)T cells at d10, and collagen at d28 post-transplantation...

Thromboangiitis obliterans (Buerger's disease) is systemic vasculitis with predominant development of thrombotic occlusions of small-to-medium diameter arteries of distal portions of both upper and lower limbs. A distinctive feature of Buerger's disease from other vasculitides is the involvement of the venous bed into the pathological process in the form of migrating thrombophlebitis. The disease is encountered more often in young adult males, predominantly tobacco smokers. The clinical pattern is presented by symptoms of increasing insufficiency of blood supply of tissues of extremities...

Chronic rejection after organ transplantation is defined as a humoral- and cell-mediated immune response directed against the allograft. In lung transplantation, chronic rejection is nowadays clinically defined as a cause of chronic lung allograft dysfunction (CLAD), consisting of different clinical phenotypes including restrictive allograft syndrome (RAS) and bronchiolitis obliterans syndrome (BOS). However, the differential role of humoral and cellular immunity is not investigated up to now. Explant lungs of patients with end-stage BOS (n = 19) and RAS (n = 18) were assessed for the presence of lymphoid (B and T cells) and myeloid cells (dendritic cells, eosinophils, mast cells, neutrophils, and macrophages) and compared to nontransplant control lung biopsies (n = 21)...

BACKGROUND: Methotrexate (MTX) is potential change in immunosuppression after lung transplantation that may help to slow down the decline in lung function in bronchiolitis obliterans syndrome (BOS). METHODS: We sought to analyze the safety and efficacy of MTX in patients with BOS, by retrospective case review. RESULTS: Thirty lung allograft patients were treated with MTX for BOS after one bilateral lower lobe, nine single, 16 bilateral, and four heart-lung transplants...
