Chronic lung allograft dysfunction (CLAD) remains a major hurdle limiting long-term survival post lung transplantation. Given the clinical heterogeneity of CLAD, recently two phenotypes of CLAD have been defined [bronchiolitis obliterans syndrome (BOS) vs. restrictive allograft syndrome (RAS) or restrictive CLAD (rCLAD)]. BOS is characterized by an obstructive pulmonary function, air trapping on CT and obliterative bronchiolitis (OB) on histopathology, while RAS/rCLAD patients show a restrictive pulmonary function, persistent pleuro-parenchymal infiltrates on CT and pleuroparenchymal fibro-elastosis on biopsies...

Lung transplantation (LTx) outcome is hampered by development of chronic rejection, often manifested as the bronchiolitis obliterans syndrome (BOS). Low serum levels of thymus and activation-regulated chemokine (TARC/CCL17), a chemoattractant, measured during the first month post-LTx are predictive for BOS development. Since TARC/CCL17 promotor polymorphisms correlate with serum TARC/CCL17 levels, we investigated seven single-nucleotide polymorphisms (SNPs) within this region and their potential association with LTx outcome...

BACKGROUND: Immunosuppression therapy after lung transplantation fails to prevent bronchiolitis obliterans syndrome (BOS) in many patients, primarily a disease of the small airways. We have reported that BOS is associated with a lack of suppression of cytotoxic mediators, and proinflammatory cytokines, in peripheral blood T, NKT-like (particularly CD8+) and NK cells. We also showed a loss of glucocorticoid receptor (GCR) in proinflammatory lymphocytes after transplant. It is unknown whether these proinflammatory lymphocytes target the small and/or large airways in BOS...

PURPOSE: Rituximab is an anti-CD20 monoclonal antibody that is used to suppress B-cell function in graft-versus-host-disease (GVHD). We sought to determine the effects of rituximab treatment on lung function in those patients with bronchiolitis obliterans syndrome (BOS) as a manifestation of GVHD. METHODS: Thirteen patients were treated with rituximab with a diagnosis of BOS and a significant reduction in the forced expiratory volume in 1 s (FEV1) after hematopoietic stem cell transplantation (HSCT)...

BACKGROUND Development of bronchiolitis obliterans syndrome (BOS) is a great limitation for patient survival in lung transplantation (LTx). A curative treatment for BOS is still missing, and in terminal stages re-transplantation (Re-LTx) is the only salvation. It is possible to slow the progress of BOS if it is detected at an early stage. This might be possible by assessing pulmonary function pattern. MATERIAL AND METHODS Between 1990 and 2014, 278 patients underwent LTx at Skåne University Hospital, Sweden...

Interleukin 17A (IL-17A) and complement (C') activation have each been implicated in the pathogenesis of idiopathic pulmonary fibrosis (IPF). We have reported that IL-17A induces epithelial injury via TGF-β in murine bronchiolitis obliterans; that TGF-β and the C' cascade present signaling interactions in mediating epithelial injury; and that the blockade of C' receptors mitigates lung fibrosis. In the present study, we investigated the role of IL-17A in regulating C' in lung fibrosis. Microarray analyses of mRNA isolated from primary normal human small airway epithelial cells indicated that IL-17A (100 ng/ml; 24 h; n = 5 donor lungs) induces C' components (C' factor B, C3, and GPCR kinase isoform 5), cytokines (IL8, -6, and -1B), and cytokine ligands (CXCL1, -2, -3, -5, -6, and -16)...

The characteristics of Mycoplasma pneumonia (M. pneumoniae)-associated bronchiolitis obliterans (BO) are not well known. We retrospectively reviewed 17 patients with M. pneumoniae-associated BO. All patients had M. pneumoniae-associated acute bronchiolitis prior to the development of BO. In the acute bronchiolitis stage, all patients had fever and cough; six patients also had wheezing and dyspnoea. BO was diagnosed approximately 1.5-8 months later based on clinical manifestations and chest high-resolution computed tomography (HRCT) findings...

Paraneoplastic pemphigus (PNP) is a rare, fatal, paraneoplastic autoimmune mucocutaneous blistering disease, commonly associated with lymphoproliferative disorders, including malignant lymphomas. Lymphoproliferative disorders associated with PNP are sometimes associated with a serious lung complication, bronchiolitis obliterans (BO). Due to its rarity, guidelines for the management of PNP have not been established. Furthermore, most patients die within 1 year. Here we report the successful treatment of lymphoma-associated PNP and BO using R-CHOP chemotherapy...

BACKGROUND: Chronic lung allograft dysfunction and its main phenotypes, bronchiolitis obliterans syndrome (BOS) and restrictive allograft syndrome (RAS), are major causes of mortality after lung transplantation (LT). RAS and early-onset BOS, developing within 3 years after LT, are associated with particularly inferior clinical outcomes. Prediction models for early-onset BOS and RAS have not been previously described. METHODS: LT recipients of the French and Swiss transplant cohorts were eligible for inclusion in the SysCLAD cohort if they were alive with at least 2 years of follow-up but less than 3 years, or if they died or were retransplanted at any time less than 3 years...

A 57-year-old woman with SAPHO (synovitis-acne-pustulosis-hyperostosis-osteitis) syndrome presented with recurrent episodes of pneumonia. She was treated with multiple courses of antibiotics with no success. The transbronchial biopsy undertaken via bronchoscopy revealed organising pneumonia (OP). She was treated with steroids and responded well with full clinical recovery and normalisation of her chest X-ray.To our knowledge, this is the first reported case of OP in association with SAPHO syndrome. This case report highlights the importance of considering OP in patients with SAPHO syndrome who present with chest infection...

BACKGROUND: Long-term survival of lung transplant recipients (LTRs) is limited by the occurrence of bronchiolitis obliterans syndrome (BOS). Recent evidence suggests a role for microbiome alterations in the occurrence of BOS, although the precise mechanisms are unclear. In this study we evaluated the relationship between the airway microbiome and distinct subsets of immunoregulatory myeloid-derived suppressor cells (MDSCs) in LTRs. METHODS: Bronchoalveolar lavage (BAL) and simultaneous oral wash and nasal swab samples were collected from adult LTRs...

Bronchiolitis obliterans syndrome (BOS) after hematopoietic stem cell transplantation (HSCT) is a major cause of morbidity and mortality with limited treatment options. Lung transplantation (LTX) has been rarely reported as a treatment option for selected HSCT recipients with this problem. In the present study, we reported six patients who underwent LTX due to BOS after HSCT (two females, four males) from January 2012 to December 2014 in our center. The median time from HSCT to diagnosis of BOS was 2.5 years (ranging from 1 to 5 years)...

A successful outcome after lung transplant was achieved using lungs donated from a teenage boy who underwent prolonged mechanical ventilation. The donor experienced hypoxic brain damage and was declared brain dead 324 days after tracheal intubation. At the time of referral, the donor's lungs revealed diffuse radiologic infiltration and atelectasis but excellent function, with a PaO2/FiO2 ratio of 450. The lungs were transplanted to a 10-year-old girl with bronchiolitis obliterans. She developed grade 2 primary graft dysfunction, but recovered quickly...
