Increased risk of chronic graft-versus-host disease, obstructive bronchiolitis, and alopecia with busulfan versus total body irradiation: long-term results of a randomized trial in allogeneic marrow recipients with leukemia. Nordic Bone Marrow Transplantation Group. (1/382)

Leukemic patients receiving marrow from HLA-identical sibling donors were randomized to treatment with either busulfan 16 mg/kg (n = 88) or total body irradiation ([TBI] n = 79) in addition to cyclophosphamide 120 mg/kg. The patients were observed for a period of 5 to 9 years. Busulfan-treated patients had an increased risk of veno-occlusive disease (VOD) of the liver (12% v 1%, P =.01) and hemorrhagic cystitis (32% v 10%, P =.003). Acute graft-versus-host disease (GVHD) was similar in the two groups, but the 7-year cumulative incidence of chronic GVHD was 59% in the busulfan-treated group versus 47% in the TBI group (P =.05). Death from GVHD was more common in the busulfan group (22% v 3%, P <.001). Obstructive bronchiolitis occurred in 26% of the busulfan patients but in only 5% of the TBI patients (P <.01). Complete alopecia developed in 8 busulfan patients and partial alopecia in 17, versus five with partial alopecia in the TBI group (P <.001). Cataracts occurred in 5 busulfan-treated patients and 16 TBI patients (P =.02). The incidence of relapse after 7 years was 29% in both groups. Seven-year transplant-related mortality (TRM) in patients with early disease was 21% in the busulfan group and 12% in the TBI group. In patients with more advanced disease, the corresponding figures were 64% and 22%, respectively (P =.004). Leukemia-free survival (LFS) in patients with early disease was 68% in busulfan-treated patients and 66% in TBI patients. However, 7-year LFS in patients with more advanced disease was 17% in the busulfan group versus 49% in the TBI group (P <.01). In patients with chronic myeloid leukemia (CML) in first chronic phase, 7-year LFS was 72% and 83% in the two groups, respectively.  (+info)

Bilateral pneumothoraces with multiple bullae in a patient with asymptomatic bronchiolitis obliterans 10 years after bone marrow transplantation. (2/382)

A 16-year-old boy developed bronchiolitis obliterans (BO) 10 years after BMT for myelodysplastic syndrome. Although the patient complained of almost no dyspnea on exertion, he had mild hypercapnea with a markedly reduced forced expiratory volume of 0.32 l. Chest X-rays showed occasional bilateral minimal pneumothoraces, which is in accordance with the existence of multiple small bullae found on the pleural surface at video-assisted thoracic surgery. Histologic examination of the biopsied lung revealed BO. This case indicates that BO in adolescence following BMT and possible chronic GVHD may be masked because of lung immaturity at BMT, and BO after BMT may be associated with multiple pleural bullae.  (+info)

Constrictive bronchiolitis obliterans and paraneoplastic pemphigus. (3/382)

Constrictive bronchiolitis obliterans is rare, and the pathogenesis of the disease often remains unknown. This study reports on the case of a 38 yr-old female with constrictive bronchiolitis obliterans and paraneoplastic pemphigus associated with malignant lymphoma. The patient developed progressive obstructive lung disease. The chest radiograph showed almost normal lungs. Paraneoplastic pemphigus is a newly described syndrome in which patients have autoantibodies binding to some epithelia, including in the respiratory tract. The disease develops in association with non-Hodgkin's lymphomas or other malignant neoplasms. The case presented here suggests that constrictive bronchiolitis obliterans associated with paraneoplastic pemphigus may be one of the facets of autoimmune responses in this context.  (+info)

Peripheral blood allogeneic microchimerism in lung and cardiac allograft recipients. (4/382)

We have been investigating two parameters, donor antigen-specific hyporeactivity and peripheral blood allogeneic microchimerism, to determine whether these parameters will predict a chronic rejection-free state and which recipients may be candidates for steroid withdrawal. We have identified donor antigen-specific hyporeactivity for 33% (16/48) of lung and 23% (11/47) of heart recipients. For both organ groups, the hyporeactive subgroup experienced a lower incidence of chronic rejection. The probability of donor antigen-specific hyporeactivity predicting a chronic rejection-free state is 100% for lung and 91% for heart recipients. We have identified peripheral blood allogeneic microchimerism for 77% (20/26) of lung and 36% (9/25) of heart recipients tested at 12-18 months posttransplant. Donor antigen-specific hyporeactivity correlates with a critical level of donor cells in lung recipients; the probability of high peripheral blood allogeneic microchimerism levels predicting a chronic rejection-free state in lung recipients is 100%. The results in heart recipients are not as clear with a short-, but not long-term, trend of higher chimerism levels correlating with the development of donor antigen-specific hyporeactivity. These results illustrate the usefulness of immmune parameters to predict long-term graft outcome in an organ-specific manner.  (+info)

Persistent high BAL fluid granulocyte activation marker levels as early indicators of bronchiolitis obliterans after lung transplant. (5/382)

The major cause of mortality in the long-term in lung transplant recipients is chronic rejection. This is a fibroproliferative process in the small airways leading to obliterative bronchiolitis and progressive loss of lung function, both constituting the clinical entity bronchiolitis obliterans syndrome (BOS). Granulocyte activation has been implicated as one factor behind BOS. Granulocyte markers in bronchoalveolar lavage (BAL) fluid were prospectively and longitudinally studied in order to identify possible association with BOS. BAL fluid from 266 bronchoscopy procedures performed in twelve single lung, eight bilateral lung and five heart/lung transplant recipients were analysed. The majority (19 of 25) were studied for a period of 2 yrs after surgery. Myeloperoxidase (MPO), eosinophil cationic protein (ECP) and interleukin-8 (IL-8) levels were used as indirect markers of activation and attraction of granulocytes. Five patients developed BOS. Ninety-eight episodes of acute rejection, nine of bacterial infection, 19 of cytomegalovirus pneumonitis, nine of Pneumocystis carinii infection, two of aspergillus infection and two of respiratory syncytial virus infection were diagnosed. BOS patients had significantly higher mean levels of MPO, ECP and IL-8 compared to patients without BOS, irrespective of acute rejection status. Over time, the five patients with BOS had significantly elevated BAL fluid levels of MPO and ECP as well as neutrophil percentages, and in four patients this increase preceded the clinical diagnosis of BOS by several months. Elevated bronchoalveolar lavage fluid neutrophil percentage as well as levels of the granulocyte activation markers myeloperoxidase and eosinophil cationic protein appear to be early signs of development of BOS in lung transplant recipients.  (+info)

Airway neutrophilia in stable and bronchiolitis obliterans syndrome patients following lung transplantation. (6/382)

BACKGROUND: The bronchiolitis obliterans syndrome (BOS) remains the major constraint on the long term success of lung transplantation. Neutrophils have been associated with fibrosing lung conditions and have been noted to be increased in the bronchoalveolar lavage (BAL) fluid of patients with BOS. METHODS: This study was undertaken to examine neutrophil accumulation in the BAL fluid, airway wall and lung parenchyma, as well as levels of interleukin (IL)-8 in the BAL fluid, in normal controls and lung transplant recipients with and without BOS. Bronchoscopic examination included endobronchial biopsy (EBB), BAL fluid, and transbronchial biopsy (TBB) sampling. Tissue neutrophils were identified by neutrophil elastase staining on 3 microm paraffin biopsy sections and quantified by computerised image analyser. IL-8 levels were measured in unconcentrated BAL fluid by ELISA. RESULTS: Compared with controls, airway wall neutrophilia was increased in both stable lung transplant recipients and those with BOS (p<0.05). BAL neutrophils and IL-8 levels were also increased in both groups of transplant recipients compared with controls (p<0.01), the levels being significantly higher in the BOS group (p<0.01). Neutrophil numbers in the lung parenchyma were not significantly different between the two groups of lung transplant recipients. CONCLUSION: Increased levels of neutrophils are present in the airway wall and BAL fluid of lung transplant recipients with and without BOS. BAL fluid levels of IL-8 are also increased, raising the possibility that neutrophils and/or IL-8 may play a part in the pathogenesis of BOS following lung transplantation.  (+info)

Clinical and radiological characteristics of lung disease in inflammatory bowel disease. (7/382)

The pulmonary associations of inflammatory bowel disease (IBD) are poorly characterized. The clinical, physiological and high-resolution computed tomographic thorax characteristics of the lung disease in patients with IBD presenting with respiratory symptoms are described. Detailed clinical information was obtained and standard pulmonary physiological tests and thorax high-resolution computed tomography performed on 14 patients with ulcerative colitis (UC) and three with Crohn's disease (CD), 10 male, aged 38-83 yrs. Respiratory symptoms had been present for 2-50 yrs and extraintestinal manifestations were present in three (17.6%). Normal pulmonary physiology (six patients) was associated with the high resolution computed tomographic changes of bronchiectasis, mosaic perfusion and air trapping suggestive of obliterative bronchiolitis and a pattern of centrilobular nodules and branching linear opacities ("tree in bud" appearance) suggestive of either cellular bronchiolitis or bronchiolectasis with mucoid secretions. Bronchiectasis was found in 13 patients (11 UC, 2 CD), 11 had air trapping and five had a "tree in bud" appearance on computed tomography. One patient had a predominantly peripheral reticular pattern at the lung bases similar to that found in cryptogenic fibrosing alveolitis and one patient had a mixed reticular and ground-glass pattern in the midzones with a patchy distribution in the central and peripheral portions of the lungs with air trapping. Eleven patients (three with alveolitis) exhibited a clinical and/or physiological response to steroids. Pulmonary abnormalities in ulcerative colitis and Crohn's disease can present years after the onset of the bowel disease and can affect any part of the lungs. Early recognition is important as they can be strikingly steroid-responsive.  (+info)

B7-1, B7-2 and class II MHC molecules in idiopathic pulmonary fibrosis and bronchiolitis obliterans-organizing pneumonia. (8/382)

Interstitial lung diseases are thought to be associated with the infiltration of activated T-lymphocytes. To induce an effective immune response, antigen-presenting cells have to not only present antigenic peptide with major histocompatibility complex (MHC) molecules to T-lymphocytes but also express B7 molecules. Therefore, the expression of B7-1, B7-2 and class II MHC molecules was investigated in lung tissues from patients with idiopathic pulmonary fibrosis (IPF) and bronchiolitis obliterans-organizing pneumonia (BOOP), and in normal lung parenchyma as a control, using immunohistochemical localization. B7-1 and B7-2 were aberrantly expressed in bronchiolar and alveolar epithelial cells, and class II MHC molecules were also aberrantly expressed in bronchiolar epithelial cells in IPF. B7-1 was aberrantly expressed in bronchiolar epithelial cells in BOOP. There was no significant difference in the expression of these proteins in alveolar macrophages between IPF and control subjects. However, B7-2 and class II MHC molecule expression in alveolar macrophages was decreased in BOOP compared with that in control subjects. Expression of CD28 and CTLA4, receptors for B7 molecules, was detected in infiltrating lymphocytes in lung tissues in IPF and BOOP. It was concluded that bronchiolar and alveolar epithelial cells may actively participate in the pathophysiology of idiopathic pulmonary fibrosis through the aberrant expression of B7 and class II major histocompatibility complex molecules. The dysregulation of these molecules in epithelial cells may lead to the activation of autoreactive T-lymphocytes, which might contribute to the pathogenesis of fibrosing lung diseases.  (+info)

N2 - The long-term prognosis of lung transplant recipients is primarily limited by a decay of pulmonary function that is attributable to chronic graft rejection, also known as bronchiolitis obliterans. Because early detection is considered a prerequisite for effective treatment, computed tomography of the lung has been proposed to predict the occurrence of bronchiolitis obliterans, and bronchiectasis has been cited as one important CT sign of this entity. The diagnostic powers of this sign, however, are limited, and the absence of bronchiectasis does not exclude bronchiolitis obliterans..

Bronchiolitis obliterans syndrome (BOS) is a form of chronic lung allograft dysfunction that affects a majority of lung transplant recipients and is the primary factor limiting long-term transplant survival. It is characterized by progressive airflow obstruction resulting in acute rejection of the graft, followed by infections, or other coexistent condition.. It is an uncommon respiratory disease characterized by fixed airway obstruction, where the bronchioles in the lung become narrowed or blocked by fibrous tissue. The disease is disabling and can be potentially severe. It may be caused occupationally by accidental, acute, high concentration exposure to industrial gases, such as nitrogen dioxide etc.. Bronchiolitis obliterans can also be associated with rheumatoid arthritis and graft-versus-host disease following a lung or hematopoietic cell transplantation. Exposure to certain food flavoring agents, notably the buttery food flavoring agent diacetyl, with the development of bronchiolitis ...

In this analysis, we considered the effects of a common promotor polymorphism of the lipopolysaccharide receptor CD14 associated with increased transcriptional activity upon the development of posttransplant rejection and graft survival. Genotyping was performed in 226 lung transplant recipients well characterized with regards to clinical outcomes. An earlier onset of acute rejection, bronchiolitis obliterans syndrome (BOS) and worse posttransplant ...
In 2002 the International Society for Heart and Lung Transplantation (ISHLT) modified the 1993 criteria for the bronchiolitis obliterans syndrome (BOS, obliterative bronchiolitis).
Chronic allograft dysfunction in form of bronchiolitis obliterans is the most important hurdle to improved longterm survival after clinical lung transplantation to date. Recently, it was observed that the progression of bronchiolitis obliterans in lung transplant recipients might be inhibited by macrolide antibiotics. The authors therefore tested whether macrolide therapy can attenuate fibrous obliteration of airways in an animal model of bronchiolitis obliterans. Rats with heterotopic tracheal allografts were treated intraperitoneally with clarithromycin and compared to untreated transplanted animals with respect to allograft histology and expression of selected cytokines. At day 21 after transplantation, the tracheal allografts of treated animals were free of fibrous material or partially occluded dependent of clarithromycin dosage. Untreated animals had completely obliterated allografts. In treated animals, tumor necrosis factor alpha (TNF-alpha) was down-regulated early (5 days) and late (21 ...

Bronchiolitis obliterans (OB) is a lesion that results when injury to small conducting airways is repaired by a proliferation of fibrous granulation tissue. Bronchiolitis obliterans has emerged as a main cause of morbidity and mortality in the setting of lung and heart-lung transplantation. Endothelin-1 lET-1), initially discovered as a vasoconstrictive peptide, has a mitogenic activity on vascular smooth cells and airway epithelial cells. Overproduction of endothelin has been reported in patients with OB or chronic rejection after lung transplantation. It is still undetermined whether locally overexpressed ET-1 has a potential impact in the ...
Lung transplant survival is usually limited by obliterative bronchiolitis (OB), but the mechanisms of OB development are unknown. CD4, T-cells, lung transplantation, Th17 cells, STAT3, T-cells Introduction Lung transplantation is usually a useful therapeutic option for patients with end-stage lung diseases. The major obstacle limiting lung transplant survival and function is usually chronic lung allograft dysfunction (CLAD), Cichoric Acid IC50 with one of the major manifestations being obliterative bronchiolitis (OB) with fibrous obliteration of the airways (1). Progressive air passage injury mediated by ongoing alloimmune and nonalloimmune responses to the lung allograft is usually thought to be the precursor of subsequent graft CALML3 fibrosis (2). OB/BOS remains one of the major limitations to long term success of lung transplant with approximately 50% of lung transplant recipients affected by 5 years (3). Recently, IL-17 and T helper 17 (Th17) cells have been linked to OB/BOS development ...
The development of bronchiolitis obliterans in the allograft lung does not necessarily mean that it is due to immunologic activity. Numerous causes of small airway scarring have been recognized in lung transplant and non-transplant patients. Particularly relevant to the lung allograft recipient is the role of infection. Numerous infectious agents (to which the immunocompromised lung recipient is exposed) have been documented to cause bronchiolitis obliterans. These include many bacterial infections, viral infections, and some atypical organisms, including mycoplasma and chlamydia. In our practice, if we note histologic OB after a non-rejection related inflammatory process, we are certain to note this etiology in our pathology reports so that patients are not treated as for rejection induced OB. Second the development of acute harvest (ischemic) injury to the lung parenchyma has been associated with airway and interstitial scarring. This is particularly relevant in individuals who experience ...

Traffic-related air pollution, as estimated by the proximity of the home to a major road, is a major risk factor for BOS and mortality after lung transplantation. The risk was present in either a dichotomous or a continuous analysis, and was not affected by adjustments for relevant covariables. Indicators of pulmonary (BAL neutrophils, IL-6) and systemic (plasma CRP) inflammation, which are probably involved in the onset of BOS, were also associated with proximity to traffic.. The strengths of our study include the relatively large lung transplant population from a single centre and the statistically robust associations. The statistical significance of our observations follows in part from the high incidence of BOS and mortality. The robustness of the associations is apparent from the fact that inclusion of relevant potential confounders, ranging from SES, transplantation-related characteristics to active smoking, tended to increase the risk estimates.18. Many other authors have estimated ...
Importance: Bronchiolitis obliterans syndrome has been associated with increased morbidity and mortality after allogeneic hematopoietic stem cell transplant (HSCT). Previous studies have suggested that azithromycin may reduce the incidence of post-lung transplant bronchiolitis obliterans syndrome. Objective: To evaluate if the early administration of azithromycin can improve airflow decline-free survival after allogeneic HSCT. Design, Setting, and Participants: The ALLOZITHRO parallel-group trial conducted in 19 French academic transplant centers and involving participants who were at least 16 years old, had undergone allogeneic HSCT for a hematological malignancy, and had available pretransplant pulmonary function test results. Enrollment was from February 2014 to August 2015 with follow-up through April 26, 2017. Interventions: Patients were randomly assigned to receive 3 times a week either 250 mg of azithromycin (n = 243) or placebo (n = 237) for 2 years, starting at the time of the ...

en] A 37-year-old man with acute myeloblastic leukemia in first remission developed ulcerative colitis and bronchiolitis obliterans organizing pneumonia (BOOP) 7 months after bone marrow transplantation (BMT) from an HLA-matched brother who suffered from severe Crohns disease. BOOP occurred 20 days after idiopathic interstitial pneumonia, in the context of severe ulcerative colitis. Lung and colon biopsies showed no signs of CMV infection or GVHD. The patient was treated with oral methylprednisolone 1 mg/kg/day and his clinical status and chest X-ray improved slowly. Remarkably, the symptoms of colitis also resolved with prednisone therapy and he is now symptom-free. We hypothesize that ulcerative colitis may have been transmitted from donor to recipient (adoptive autoimmunity) and that it was complicated by BOOP. However, other factors such as CMV may have contributed to the occurrence of BOOP ...

Bronchiolitis obliterans (BO) is a disease with a poor prognosis, and a key factor that limits long-term survival after allogeneic hematopoietic stem cell transplantation (HSCT). We here report a case of a 31-year woman with acute lymphatic leukemia, which was treated by chemotherapy and HSCT, and consequently developed BO 2 years after HSCT. A non-tuberculous mycobacterial infection occurred and showed gradual exacerbation. She started taking anti-mycobacterial drugs, but lost appetite, felt tired and finally lost consciousness one month after beginning medication. Arterial blood gas revealed marked hypercapnia. Using extracorporeal life support (ECLS), the carbon dioxide concentration was reduced and her consciousness recovered. To our knowledge, this is the first case in which ECLS was successfully used for hypercapnia in a patient with BO ...
Bronchiolitis obliterans organizing pneumonia (BOOP) is defined as A disease formerly considered a form of interstitial pneumonia. Its etiology is obscure but it may be associated with toxic fumes, infection, and connective tissue disease. Clinical symptoms include cough, dyspnea and influenza-like symptoms with the development of the usual interstitial pneumonia in many cases. Obstructive symptoms are limited to smokers. There are patchy polypoid masses of intra-alveolar granulation tissue in small airway lumina and alveolar ducts. Organizing refers to unresolved pneumonia (in which the alveolar exudate persists and eventually undergoes fibrosis) in which fibrous tissue forms in the alveoli.[1] ...
A histologic term referring to two broad groups of lesions: proliferative bronchiolitis obliterans with granulation tissue polyps filling small airways, and fibrotic bronchiolitis obliterans with permanent scarring and stenosis or obliteration of airways. Proliferative bronchiolitis obliterans is often associated with organizing pneumonia in which the same reparative reaction that is present in the bronchiole extends out into more distal parenchyma. Histologic bronchiolitis obliterans may or may not be associated with clinical evidence of airway obstruction ...

BOS results from a chronic immunological/inflammatory insult to the allograft airways. This leads to a persistent peribronchiolar leukocyte infiltration, followed by an aberrant repair and fibro-obliteration of the airways. In this study, we hypothesized that the persistent expression of MCP-1 during the allogeneic response, with subsequent recruitment of activated mononuclear cells expressing CCR2, is pivotal for the promotion of the pathogenesis of BOS.. We assessed whether MCP-1 was associated with the continuum of lung allograft rejection from human acute to chronic rejection. We found significant increases in levels of MCP-1 in BALF from patients with acute rejection and BOS, compared with those found in healthy lung transplant recipients. The elevated levels of MCP-1 were biologically active as determined by mononuclear cell chemotaxis. Immunolocalization demonstrated that both airway epithelium and mononuclear cells were the predominant cellular sources of MCP-1. This association between ...
We included three studies that enrolled a total of 413 adult patients that compared tacrolimus with microemulsion or oral solution cyclosporin. All studies were found to be at high risk of bias. Tacrolimus seemed to be significantly superior to cyclosporin regarding the incidence of bronchiolitis obliterans syndrome (RR 0.46, 95% CI 0.29 to 0.74), lymphocytic bronchitis score (MD -0.60, 95% CI -1.04 to -0.16), treatment withdrawal (RR 0.27, 95% CI 0.16 to 0.46), and arterial hypertension (RR 0.67, 95% CI 0.50 to 0.89). However, the finding for arterial hypertension was not confirmed when analysed using a random-effects model (RR 0.54, 95% CI 0.17 to 1.73). Furthermore, trial sequential analysis found that none of the meta-analyses reached the required information sizes and cumulative Z-curves did not cross trial sequential monitoring boundaries. Diabetes mellitus occurred more frequently among people in the tacrolimus group compared with the cyclosporin group when the fixed-effect model was ...

To the Editors:. In order to distinguish the effects of lung disease from those of normal growth and development, lung function is expressed in comparison with reference data, with forced expiratory volume in 1 s (FEV1) commonly being presented as % predicted. FEV1 % pred has been identified as being of prognostic value in cystic fibrosis (CF), such that an FEV1 of ,30% pred or rapid decline to that level should prompt referral to a transplant centre [1]. Subsequent monitoring of FEV1 % pred after lung transplantation is also important for monitoring graft function and is required to detect any signs of rejection or onset of bronchiolitis obliterans syndrome (BOS), a disease defined as a fall in FEV1 of ,20% from baseline determined by the average of two measurements made ≥3 weeks apart. Continuing to monitor FEV1 % pred after the development of BOS has also been shown to provide important insight into the patients prognosis and therapeutic options [2].. Given that FEV1 % pred plays such a ...
Lung transplantation is hampered by bronchiolitis obliterans syndrome (BOS), although recently azithromycin treatment has a published response rate of about 42% in patients with established BOS. We linked this improvement to a reduction in airway neutrophilia and IL8. In the present study, we further investigated the intracellular mechanisms of azithromycin, looking at the possible involvement of mitogen-activated-protein kinases (MAPK) and oxidative stress. Simultaneously, currently used immunosuppressive agents were investigated. Human primary airway smooth muscle cells were stimulated with IL17 and incubated with increasing concentrations of steroids, immunosuppressive agents (tacrolimus, cyclosporine and rapamycin) or macrolides (erythromycin and azithromycin). We measured supernatant IL8 protein, 8-isoprostane and cell lysate MAPK. IL17-induced IL8 production was decreased by both erythromycin and azithromycin. In nonstimulated condition, IL8 production only increased at the highest dose of ...

The differential diagnosis for centrilobular densities generally falls into the category of peribronchiolar disease, but may include perilymphatic or perivascular disease. Centrilobular densities with a tree-in-bud appearance are usually due to endo/peribronchiolar diseases and may be seen with bronchopneumonia (particularly in regions peripheral to frank consolidation), bronchiectasis and cystic fibrosis, bronchogenic spread of tuberculosis, bronchiolitis obliterans and bronchiolitis obliterans organizing pneumonia, respiratory bronchiolitis, and hypersensitivity pneumonia [2]..

Researchers at the Harvard T.H. Chan School of Public Health published a study in Environmental Health Perspectives. They tested a variety of flavored electronic cigarettes and refill liquids and found that 75 percent of them had a flavoring chemical (Diacetyl) that has been linked to cases of severe respiratory disease.. This chemical diacetyl has become infamous by causing a debilitating respiratory disease known as popcorn lung (bronchiolitis obliterans). Bronchiolitis obliterans is an irreversible loss of pulmonary function that can become so severe that the only treatment option may be a lung transplant.. E-cigarettes are on the rise and the FDA is trying to secure the ability to regulate them along with other tobacco and nicotine products. However, because of the lack of regulation, there are potential detrimental health effects in these products, but not many people know about them.. Concerns regarding e-cigarettes primarily focus on nicotine exposure, second-hand exposure, the potential ...
Toxic popcorn sounds like a misnomer. Low in calories and high in fiber, popcorn is often seen as a healthy alternative to other snack foods. But a toxic chemical called diacetyl that is used to give microwave popcorn a buttery flavor has been linked to a debilitating lung disease called bronchiolitis obliterans †otherwise known as “Popcorn Workers Lung.†Now, one of the largest microwave popcorn makers in the country has decided to discontinue use of diacytle. But despite findings that tie diacytle exposure to the dangerous lung disorder, the Food and Drug Administration (FDA) insists that the chemical is safe for consumers. And most other microwave popcorn makers continue to include diacytle in their product †even though they don’t always list the chemical on ingredient labels.. Bronchiolitis obliterans is a form of fixed lung disease that makes it difficult for air to flow out of the lungs. The ...
Collagen Tissue Disease–associated Interstitial Lung Fibrosis (CTD-ILDs) and Bronchiolitis Obliterans Syndrome (BOS) represent severe lung fibrogenic disorders, characterized by fibro-proliferation with uncontrolled extracellular matrix deposition. Hyaluronic acid (HA) plays a key role in fibrosis with its specific receptor, CD44, overexpressed by CTD-ILD and BOS cells. The aim is to use HA-liposomes to develop an inhalatory treatment for these diseases. Liposomes with HA of two molecular weights were prepared and characterized. Targeting efficiency was assessed toward CTD-ILD and BOS cells by flow cytometry and confocal microscopy and immune modulation by RT-PCR and ELISA techniques. HA-liposomes were internalized by CTD-ILD and BOS cells expressing CD44, and this effect increased with higher HA MW. In THP-1 cells, HA-liposomes decreased pro-inflammatory cytokines IL-1β, IL-12, and anti-fibrotic VEGF transcripts but increased TGF-β mRNA. However, upon analyzing TGF-β release from

Colorful pinwheel pins are appearing in the community. They symbolize air circulation and will be used to aid in a fundraising campaign for CHILD, a research foundation for rare childhood lung diseases. The last week in February is CHILD week and the campaign will run until the second week in March.. Sun Lakes residents Penny and Ron Petersen will spearhead the Sun Lakes campaign. Their grandson, Harrison Steiner, has Bronchiolitis Obliterans, an extremely rare lung condition. Harrys mom, Daisy, is an Arizona representative for CHILD and urges the public to become aware of the impact rare childhood diseases can have on a family and community.. Because of the rareness of the diseases, there is virtually no government or large funding sources. When there are only five to 25 kids in the country with an illness, drug companies dont find it profitable to research treatment options. Parents of children with Bronchiolitis Obliterans and several other rare lung conditions have joined together to ...
2,3-Butanedione (BD) is a reactive diketone in artificial butter flavors that is thought to cause bronchiolitis obliterans in workers in microwave popcorn manufacturing. Bronchiolitis obliterans is generally not diagnosed until irreversible damage has occurred; therefore a biomarker of early exposure is needed. The potential systemic uptake of BD from inhalation exposure has not been evaluated. The objective here was to evaluate the systemic exposure of BD and binding to hemoglobin and albumin.

Because chronic lung allograft dysfunction (CLAD) develops predominantly on one side after bilateral living-donor lobar lung transplantation (LDLLT), lung perfusion scintigraphy (Q-scinti) was expected to show a perfusion shift to the contralateral unaffected lung with the development of CLAD. Our study examined the potential usefulness of Q-scinti in the diagnosis of CLAD after bilateral LDLLT. We conducted a single-center retrospective cohort study of 58 recipients of bilateral LDLLT. The unilateral shift values on Q-scinti were calculated and compared between the CLAD group (N=27) and the non-CLAD group (N=31) from 5 years before to 5 years after the diagnosis of CLAD. The unilateral shift values in Q-scinti were significantly higher in the CLAD group than in the non-CLAD group from 5 years before the diagnosis of CLAD to 5 years after the diagnosis ( ...
This case series describes 7 patients with severe chronic graft-versus-host disease (cGvHD) associated with bronchiolitis obliterans (BO) after allogeneic hematopoietic stem cell transplantation (HCT) who underwent lung transplantation. About 20% of patients with severe cGVHD develop BO, which portends a poor prognosis. Lung transplantation may be performed for severe refractory BO. In this group, 6 patients underwent bilateral lung transplantation and 1 underwent single lung transplantation. Explanted lung pathology confirmed BO in all patients. The median survival after lung transplantation in this group was 24 months. The authors conclude that lung transplantation is a possible therapeutic option for certain patients with severe therapy-refractory BO.. ...
TY - JOUR. T1 - Lung transplantation. T2 - Chronic allograft dysfunction and establishing immune tolerance. AU - Gracon, Adam S.A.. AU - Wilkes, David S.. PY - 2014/8. Y1 - 2014/8. N2 - Despite significant medical advances since the advent of lung transplantation, improvements in long-term survival have been largely unrealized. Chronic lung allograft dysfunction, in particular obliterative bronchiolitis, is the primary limiting factor. The predominant etiology of obliterative bronchiolitis involves the recipients innate and adaptive immune response to the transplanted allograft. Current therapeutic strategies have failed to provide a definitive treatment paradigm to improve long-term outcomes. Inducing immune tolerance is an emerging therapeutic strategy that abrogates allograft rejection, avoids immunosuppression, and improves long-term graft function. The aim of this review is to discuss the key immunologic components of obliterative bronchiolitis, describe the state of establishing immune ...

Researchers have shown for the first time that lung transplant patients in Europe who live on or near busy roads with high levels of air pollution are more likely to die or to experience chronic organ rejection, than those living in less polluted areas.. Dr David Ruttens, from the University of Leuven (Belgium) told the European Respiratory Societys International Congress today (29 September, 2015) that the risk of dying increased by 10% for patients living in an area where air pollution was above World Health Organization (WHO) recommended maximum levels, compared with patients living in areas with lower levels of pollution. However, this increased risk was not seen in lung transplant patients who were taking a class of antibiotics called macrolides, which include azithromycin and clarithromycin.. WHO estimates that 3.7 million people worldwide die prematurely every year as a result of exposure to small particulate matter measuring between 2.5-10 micrometers in diameter (known as PM10).

Champlin2, Burton F. Dickey1. Morbidity and mortality from bronchiolitis obliterans syndrome (BOS) remain unacceptably high after allogeneic hematopoietic cell transplantation (A-HCT) (1). Prompt diagnosis may improve outcomes (2). Adherence to home-based spirometry (HS) in lung allograft recipients is high, supporting the feasibility of BOS surveillance (3-6). Low adherence to HS has been a barrier to implementation after A-HCT (7-10), possibly due to psychosocial burnout and fatigue (11, 12). The goal of this pilot study was to: 1) determine the feasibility and validity of HS real- time telemonitoring in A-HCT ...
There is significant variability in lung transplant centers approach to HLA (human leukocyte antigen) antibodies, creating heterogeneity regarding their clinical significance. Some institutions use beads coated with multiple HLA to screen candidate sera and then use single antigen beads (SAB) to determine antibody identity if the pre-screen is positive. Other centers do not pre-screen, using SAB alone, which may detect low-level antibodies of unknown significance. The primary objective of this study was to review the current literature to identify sources of heterogeneity in the identification of pre- and post-lung transplant HLA antibodies, particularly regarding antibody detection methods. A random effects model meta-analysis was used to evaluate the relationship between pre-transplant HLA antibodies and the development of de novo donor specific antibodies (dnDSA) and dnDSA and chronic lung allograft dysfunction (CLAD). Each outcome was stratified by method of antibody detection (pre-screen ...

Objectives: Four diacetyl workers were found to have bronchiolitis obliterans syndrome. Exposures, respiratory symptoms, lung function and exposure-response relationships were investigated.. Methods: 175 workers from a plant producing diacetyl between 1960 and 2003 were investigated. Exposure data were used to model diacetyl exposure. Lung function and questionnaire data on respiratory symptoms were compared to a general population sample and respiratory symptoms to an internal reference group.. Results: Workers were potentially exposed to acetoin, diacetyl, acetaldehyde and acetic acid. Historic diacetyl exposure ranged from 1.8 to 351 mg/m3, and from 3 to 396 mg/m3 for specific tasks. Diacetyl workers reported significantly more respiratory symptoms compared to the general population sample (continuous trouble with breathing (prevalence ratio (PR) = 2.6; 95% CI 1.3 to 5.1), daily cough (PR = 1.5; 95% CI 1.1 to 2.1), asthma attack (ever) (PR = 2.0; 95% CI 1.2 to 3.4), doctor diagnosed asthma ...

Bronchiolitis obliterans with organizing pneumonia (BOOP), originally described in 1985, is now more appropriately called cryptogenic organizing pneumonia (COP). It is one of the acute/subacute idiopathic interstitial pneumonias, along with Idiopathic Pulmonary Fibrosis and Acute Interstitial Pneumonia, among others.. COP is a rare pulmonary disorder characterized by dry cough, fever, dyspnea, and pulmonary infiltrates. The etiology is not thought to be infectious, and so it is usually recognized when a patient with presumed bacterial pneumonia does not respond to antibiotic therapy. COP is usually responsive to steroids. Pathologically, the disease begins with a proliferative bronchiolitis obliterans picture that progresses to organizing pneumonia. ...
A 17-year-old Asian man presented with a spontaneous pneumothorax, which was treated initially by needle aspiration. It recurred within a week with complete right-sided pneumothorax requiring water-sealed intercostal drainage. The air leak persisted after one week and the patient developed pyrexia with associated neutrophilia and raised serum inflammatory markers. A chest radiograph showed a hydro-pneumothorax and culture of the pleural fluid grew Pseudomonas aeruginosa and Methicillin-resistant Staphylococcus aureus (MRSA). He was treated with intravenous Piperacillin-Tazobactam resulting in a full clinic-radiological recovery.. A week later his fever returned and repeat chest radiograph showed right middle and lower lobe consolidation associated with recurrent hydro-pneumothorax. A new intercostal drain was inserted and he was intubated and ventilated due to the rapid onset of severe respiratory distress. Computed tomogram (CT scan) of the chest confirmed bilateral patchy consolidation in ...

Chronic lung allograft dysfunction (CLAD) is, in one sense, a term without a true consensus definition, although its common usage in the field of lung transplantation implies a base understanding throughout the community that it describes a lung allograft that does not work (well) [1]. There appears to be general agreement that CLAD most commonly occurs in a time-dependent fashion after transplant and is a harbinger of a foreshortened survival [2]. However, different phenotypes have been described based on a combination of physiological and radiological features [3]. A restrictive ventilatory defect, with or without interstitial pulmonary infiltrates and/or pleural thickening, has the worst prognosis and is also associated with inferior results from attempts at salvage by retransplantation [4]. One curious feature of the natural history of CLAD is the chameleon-like property of morphing from one predominant phenotype to another [5]. Perhaps this bespeaks our simplistic understanding of the root ...

2016 International Society for Heart and Lung Transplantation. Background The diagnosis of antibody-mediated rejection (AMR) in the lung transplant is still an area under investigation. We performed a blinded multicenter study to determine if any statistically significant histologic findings in transbronchial biopsy specimens from lung transplant patients correlate with the presence of donor-specific antibodies (DSAs). Methods We asked 9 pathologists with experience in lung transplantation to evaluate 161 lung transplant biopsy specimens for various histologic parameters. The findings were correlated with antibody status positive for DSAs, positive for non-DSAs, and no antibodies (NABs) present. The significance of each histologic variable was reviewed. Results We found no statistically significant association with acute cellular rejection, airway inflammation, or bronchiolitis obliterans and the presence or absence of antibodies. However, biopsy specimens with DSAs had a statistically ...

Caucasian and Hispanic children who undergo lung transplantation appear to be at greater risk for developing chronic kidney disease, or CKD, according to a small retrospective study conducted at Texas Childrens Hospital.
Mac-Leod syndrome (syn.: Swywer-James-syndrome) is a manifestation of postinfectious obliterative bronchiolitis. The involved lung or portion of the lung does not grow normally and is slightly smaller than the opposite lung (2). Radiographically, pulmonary hyperlucency caused by overdistended alveoli combined with diminished arterial flow characterizes its imaging appearance. The lung is expected to grow by progressive alveolarization in a child between the age of 2 and 8 years. Thereafter, lung growth is related to hyperexpansion of the existing alveoli. Mac-Leod syndrome is characterized by diminished vascularity, arrest of progressive growth and alveolarization of the lung and resultant hypoplasia . Multifocal areas of air trapping may be seen. Patients with Mac-Leod syndrome have a small lung, compensatory overexpansion of the contralateral lung, peripheral bronchi and bronchioles pruned secondary to obliterative bronchiolitis, a mosaic pattern of hyperlucency on CT, and small vessels and ...

Over a decade ago major popcorn manufacturers removed diacetyl from their products because of deaths and hundreds of cases of bronchiolitis obliterans, a serious and irreversible lung disease. But some people are still being exposed to diacetyl - not through food flavorings as a worksite hazard, but through e-cigarette vapor.

In addition to activation of plasminogen, uPA stimulates proliferation of epithelial cells (26, 48, 89). uPA induces proliferation in several cell lines including lung epithelial cells, and the process appears to be uPAR-dependent (43, 50, 76-79, 82). In addition, the uPA-uPAR system exhibits cooperativity with selected integrins to induce phenotypic changes in epithelial cells exposed to hypoxia that are similar to epithelial-mesenchymal transition. Newly recognized pathways by which the lung epithelium can regulate the uPA-uPAR-PAI-1 fibrinolytic system include regulation through uPA signaling, uPA-induced mediator expression, and cross talk between uPA and p53 by which uPA can regulate epithelial cell viability.. A wide range of lung diseases including ARDS, interstitial lung diseases, bronchiolitis obliterans, and drug-induced lung diseases are characterized by lung epithelial cell apoptosis. The interstitial lung diseases are characterized by the development of progressive fibrosis, and ...
Answer 1. What type of tissue fills the RB (respiratory bronchiole) and extends upward and toward the left between the arrows? Granulation tissue. What is the diagnosis of this process? Bronchiolitis obliterans organizing pneumonia-like/cryptogenic organizing pneumonia-like pattern (granulation tissue in airway and adjacent alveoli) Answer 2. What cells are causing the thickening, and what cells predominate in the alveolar spaces? The alveolar wall thickening is caused by myofibroblasts, interstitial lymphoid cells, and type II cells. Macrophages predominate in the alveolar spaces. What is the homogeneous pink material in the alveoli? Protein-rich edema fluid that has sufficient protein to stain with the eosin stain.. ...

BACKGROUND: Cases of H1N1 and other pulmonary infections evolve to acute respiratory failure and death when co\infections or lung injury predominate over the immune response, thus requiring early diagnosis to improve treatment. of airways obliteration and dysfunction on innate immunity, suggesting that treatment should be focused on epithelial repair. was isolated from a blood culture (patients 2 and 3) and spp were identified in tracheal aspirate specimens (patient 1). Patients 1, 2 and 4 are alive, but patients 3 and 5 died of respiratory failure, with concurrent congestive heart failure, hepatic encephalopathy, and acute renal failure. Table 1 Clinical features of the patients. Necrotizing Bronchiolitis, Collapsogenic Diffuse Alveolar Damage and Alveolar Hemorrhage Figure 1 depicts the pathological findings in the surgical lung biopsy specimens. The main pathological features were necrotizing bronchiolitis, clastogenic diffuse alveolar damage (DAD), and alveolar hemorrhage (Table 2). ...
In this study we have adopted a multifunctional approach to identification of EMT ex vivo using cell morphology, upregulation of mesenchymal proteins, downregulation of epithelial proteins, secretion of ECM and a functional assessment of invasive and migratory capacity. This multifunctional approach is likely to be much more robust than reliance on any single marker of EMT. In addition, our quantitative immunohistochemistry has demonstrated reduced epithelial E-cadherin expression and increases in vimentin and α-SMA expression in the airway epithelium of patients with BOS compared with stable recipients and control lung samples.. The results of this study add significantly to the understanding gained from our previously reported pilot observations in the lung transplant airway.10 The present study provides a comprehensive assessment of the ability of airway epithelial cells from the transplanted lung to undergo EMT. Our observations offer significant insight into what might be an important ...

Antibody-mediated rejection (AMR) has emerged as an important cause of lung graft failure. In the current issue of the JCI, a study by Li et al. identifies a critical role of Foxp3+ T cells residing within lung allografts in the regulation of AMR. This study not only provides new insights into the nature of lung allografts as a primary site where T and B cell priming and immune regulation can occur, but also introduces the mouse orthotopic lung transplant as a model for studying the immunobiology of AMR. Because AMR can be so difficult to effectively treat in lung transplant recipients, the development of an animal model is a major advance in understanding the immunopathogenesis of AMR.. ...
