PURPOSE OF REVIEW: The current review highlights the most relevant articles on lung infections following hematopoietic stem cell transplantation (HCT) published over the last year. Between 30 and 50% of HCT recipients will develop pulmonary infiltrates. These pulmonary complications may be infectious (caused by virus, bacteria, fungi, or protozoa) or noninfectious (e.g., fluid overload, heart failure, transfusion reactions like transfusion associated lung injury and transfusion-associated circulatory overload, drug reactions, engraftment syndrome, idiopathic pneumonia syndrome, diffuse alveolar hemorrhage, cryptogenic organizing pneumonia, and bronchiolitis obliterans syndrome)...

OBJECTIVES: Incidences of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare, but these conditions are associated with high mortality. There have been few reports of SJS and TEN in children. The aim of this study was to evaluate the clinical features and outcomes of SJS and TEN in a group of Japanese children. METHODS: We retrospectively reviewed pediatric cases of SJS and TEN, from 2000 to 2015. RESULTS: We identified 12 cases of SJS and 3 cases of TEN, among children...

A 47-year-old man who was a redo double lung transplant recipient (cytomegalovirus [CMV] status: donor positive/recipient positive; Epstein-Barr virus status: donor positive/recipient positive) presented to the hospital with 1 week of generalized malaise, low-grade fevers, and dry cough. His redo lung transplantation was necessitated by bronchiolitis obliterans syndrome, and his previous lung transplantation 5 years earlier was for silicosis-related progressive massive fibrosis. He denied any difficulty breathing or chest pain...

BACKGROUND: Cellular and molecular mechanisms of acute and chronic lung allograft rejection have yet to be clearly defined, and obliterative bronchiolitis (OB) remains the primary limitation to survival in lung transplant recipients (LTRs). We have previously shown that T-bet-deficient recipients of full major histocompatibility complex (MHC)-mismatched, orthotopic left lung transplants develop accelerated obliterative airway disease (OAD) in the setting of acute cellular rejection characterized by robust alloimmune CD8+ interleukin (IL)-17 and interferon (IFN)-γ responses that are attenuated with neutralization of IL-17...

Thromboangiitis obliterans (TAO), also known as Buerger's Disease, is an occlusive vasculitis linked with high morbidity and amputation risk. To date, TAO is deemed incurable due to the lack of a definitive treatment. The immune system and inflammation are proposed to play a central role in TAO pathogenesis. Due to their immunomodulatory effects, mesenchymal stromal cells (MSCs) are the subject of intense research for the treatment of a wide range of immune-mediated diseases. Thus far, local intramuscular injections of autologous or allogeneic MSCs have shown promising results in TAO...

Lung transplants belong in the group of organ transplants with poorer outcomes, with acute rejection and bronchiolitis obliterans being cited as major causes of this. Poor allograft evolution has been associated with multiple factors, including those related to esophagogastric disease. In patients with end-stage pulmonary conditions eligible for a lung transplant gastroesophageal reflux (GER), esophageal dysmotily, and gastroparesis are highly prevalent and worsen upon transplantation, which may compromise transplant viability...

Bronchiolitis obliterans organising pneumonia as an initial manifestation of systemic lupus erythematosus (SLE) is a rare and uncommon presentation. We describe a case of SLE presenting with shortness of breath, found to have pneumothorax, bilateral nodular infiltrates along with pleural effusions and pericardial effusion. Work-up suggested a diagnosis of active SLE with anaemia, thrombocytopenia, positive antinuclear antibodies (ANAs) and positive anti-double-stranded DNA. On retrospective review of patient records, from 8 years prior to presentation, lung biopsy histology consistent with bronchiolitis obliterans organising pneumonia with positive ANA serology was found, without any further autoimmune work-up...

Background: Acute cellular rejection (ACR) is a major risk factor for chronic lung allograft dysfunction after lung transplantation. Acute cellular rejection can persist or recur despite augmentation of immunosuppression by conventional methods. There are limited therapeutic options in treating these recurrent and refractory ACRs. We describe our experience with cyclophosphamide therapy for recurrent and refractory ACR in lung transplant recipients. Methods: Six consecutive patients who were treated with cyclophosphamide for recurrent or refractory ACR were included in the series...

Background: Combined lung-liver transplantation (LLT) applies 2 technically challenging transplants in 1 patient with severe 2-organ failure. Methods: Institutional medical records and United Network for Organ Sharing database were queried for patients at our institution that underwent LLT from 2000 to 2016. Results: Twelve LLTs were performed from 2000 to 2016 including 9 male and 3 female recipients with a median age of 28.36 years. Indications for lung transplantation were cystic fibrosis (8), idiopathic pulmonary fibrosis (3), and pulmonary fibrosis secondary to hepatopulmonary syndrome (1)...

OBJECTIVE: The purpose of this article is to review the high-resolution CT characteristics of individual obstructive and restrictive chronic lung allograft dysfunction (CLAD) phenotypes to aid in making accurate diagnoses and guiding treatment. CONCLUSION: Long-term survival and function after lung transplant are considerably worse compared with after other organ transplants. CLAD is implicated as a major limiting factor for long-term graft viability. Historically thought to be a single entity, bronchiolitis obliterans syndrome, CLAD is actually a heterogeneous group of disorders with distinct subtypes...

La bronquiolitis obliterante es una enfermedad pulmonar crónica infrecuente y grave producto de una lesión del tracto respiratorio inferior. En nuestro país, es más frecuente observarla secundaria a una lesión viral grave, en especial, por adenovirus. La bronquiolitis obliterante se caracteriza por la oclusión parcial o total del lumen de los bronquiolos respiratorios y terminales por tejido inflamatorio y fibrosis, que produce la obstrucción crónica de la vía aérea. Este consenso discute el estado actual del conocimiento en las diferentes áreas de la bronquiolitis obliterante secundaria a una lesión infecciosa...

BACKGROUND: Although, presence of donor specific antibodies (DSA) is known to impact lung allograft, limited data exists regarding DSA management. METHODS: We did a retrospective study at our center evaluating DSA management in adult lung transplant recipients undergoing lung transplantation between January 1, 2010 and June 30, 2014. Study follow up was completed through October 2017. All recipients were stratified into two groups based on the presence or absence of DSA...

Chronic lung allograft dysfunction (CLAD) with its clinical correlative of bronchiolitis obliterans syndrome (BOS) remains the major limiting factor for long-term graft survival. Currently there are no established methods for the early diagnosis or prediction of BOS. To assess the feasibility of breath collection as a non-invasive tool and the potential of breath volatile organic compounds (VOC) for the early detection of BOS, we compared the breath VOC composition between transplant patients without and different stages of BOS...

RATIONALE: Thromboangiitis obliterans (TAOs, or Buerger's disease) present as a non-atherosclerotic segmental occlusive vasculitis within medium- and small-sized blood vessels. TAO frequently occurs in young adults and is associated with cigarette smoking. At present, there are no accurately defined treatments for TAO. PATIENT CONCERNS: A 34-year-old Asian woman with a 20-year history of heavy cigarette smoking and recurrent, small, and self-limited lower limb ulcerations since adolescence, presented with persisting unhealed ulcerations on both ankles for 6 months...

Background: Until recently, a gene polymorphism in the promoter region of endothelial nitric oxide synthase has been suggested as a risk factor for thromboangiitis obliterans (TAO) development. The aim of this study was to compare the metabolites of nitric oxide (NO) and its backup, heme-oxygenase-1 (HMOX1), between TAO patients and those of a smoking control group matched by race, age, sex, and smoking habits. Methods: Twenty-four male Caucasian TAO patients and 20 male Caucasian controls enrolled in the study...

BACKGROUND: Telomere shortening has been associated with several lung diseases. However, telomere length is generally measured in peripheral blood leucocytes rather than in lung tissue, where disease occurs. Consequently, telomere dynamics have not been established for the normal human lung nor for diseased lung tissue. We hypothesized an age- and disease-dependent shortening of lung tissue telomeres. METHODS: At time of (re-)transplantation or autopsy, 70 explant lungs were collected: from unused donors (normal, n = 13) and patients with cystic fibrosis (CF, n = 12), chronic obstructive pulmonary disease (COPD, n = 11), chronic hypersensitivity pneumonitis (cHP, n = 9), bronchiolitis obliterans syndrome (BOS) after prior transplantation (n = 11) and restrictive allograft syndrome (RAS) after prior transplantation (n = 14)...
