Chronic obstructive pulmonary disease (COPD) is a major global cause of morbidity and mortality, projected to become the 3rd cause of disease mortality worldwide by 2020. COPD is characterized by persistent and not fully reversible airflow limitation that is usually progressive and is associated with an abnormal chronic inflammatory response of the lung to noxious agents including cigarette smoke. Currently available therapeutic strategies aim to ease COPD symptoms but cannot prevent its progress or regenerate physiological lung structure or function...

Mycobacterium tuberculosis (MTB) can disseminate to extra-pulmonary organs, particularly in severely immunosuppressed patients. Confirmation of active MTB infection is often difficult in subjects with contraindication for invasive procedures. We herein report a case of disseminated MTB infection after hematopoietic stem cell transplantation. Circulating cell free DNA of the patient showed positive amplification for a MTB complex specific sequence using digital PCR technique. MTB infection could be confirmed with positive acid fast stain and approved quantitative PCR assay using the liver tissue obtained at an autopsy...

BACKGROUND: Continuation of empirical antimicrobial therapy (EAT) for febrile neutropenia in patients with haematological malignancies until neutrophil recovery could prolong the therapy unnecessarily. We aimed to establish whether EAT discontinuation driven by a clinical approach regardless of neutrophil recovery would optimise the duration of therapy. METHODS: We did an investigator-driven, superiority, open-label, randomised, controlled phase 4 clinical trial in six academic hospitals in Spain...

Pulmonary hypertension is a critical problem in infants with bronchopulmonary dysplasia. This study determined the therapeutic effects of human mesenchymal stem cells (MSCs) on pulmonary hypertension in an animal model. Pregnant Sprague-Dawley rats were intraperitoneally injected with lipopolysaccharide (LPS, 0.5 mg/kg/day) on gestational days 20 and 21. The pups were randomly assigned to two treatment conditions: room air (RA) or an O2-enriched atmosphere. On postnatal day 5, they were intratracheally transplanted with human MSCs (3 × 10(5) and 1 × 10(6) cells) in 0...

Invasive fungal disease represents one of the severe complications in haematopoietic stem cell transplant recipients. We describe a case of a patient treated for relapse of chronic lymphoblastic leukaemia 6 years after HSCT. The patient was treated for invasive pulmonary aspergillosis but died 3 months later from multiple organ failures consisting of haemorrhagic necrotizing fungal pneumonia, refractory chronic hepatic graft versus host disease and cytomegalovirus hepatitis. Autopsy samples revealed histopathological evidence of fungal hyphae and an unusual Aspergillus nidulans-like species was isolated in pure culture...

Tahuanty Pena, Julia Klesney-Tait
Mycobacterial infections are uncommon in solid organ and hematopoietic stem cell transplant recipients but carry significant morbidity and mortality. Donor screening strategies for tuberculosis should be emphasized in high-risk populations. Both tuberculosis and nontuberculous mycobacterial infections can have pulmonary and extrapulmonary manifestations of infections. Recommended treatment regimens typically involve multiple drugs with significant adverse effects and drug interactions.

Lung transplantation (LTx) has evolved to represent the therapy of choice for many patients with end-stage lung diseases. Appropriate candidate selection for LTx is an important determinant of a positive outcome from transplantation. Posttransplantation survival has steadily improved, but long-term survival continues to be a challenge with a median survival of 5.8 years. Similarly, combined heart-lung transplantation and simultaneous liver-lung transplantation has been performed successfully in select patients who are not expected to survive either organ transplant alone...

As more individuals survive their hematologic malignancies after allogeneic hematopoietic stem cell transplantation (HSCT), there is growing appreciation of the late organ complications of this curative procedure for malignant and nonmalignant hematologic disorders. Late noninfectious pulmonary complications encompass all aspects of the bronchopulmonary anatomy. There have been recent advances in the diagnostic recognition and management of bronchiolitis obliterans syndrome, which is recognized as a pulmonary manifestation of chronic graft-versus-host disease...

Noninfectious acute lung injury syndromes are major causes of respiratory failure and early mortality after hematopoietic stem cell transplantation (HSCT). Pulmonary edema and transfusion-related acute lung injuries are important respiratory complications seen after HSCT and in the nontransplant setting. Early transplant-specific causes of lung injury, such as idiopathic pneumonia syndrome, are reviewed. Several complications, such as drug-induced pneumonitis and cryptogenic organizing pneumonia, that occur in both the early and later time periods after HSCT are also briefly discussed...

BACKGROUND: Despite advances in neonatal care, bronchopulmonary dysplasia (BPD) remains a significant contributor to infant mortality and morbidity. While human amnion epithelial cells (hAECs) have shown promise in small and large animal models of BPD, there is scarce information on long-term benefit and clinically relevant questions surrounding administration strategy remain unanswered. In assessing the therapeutic potential of hAECs, we investigated the impact of cell dosage, administration routes and timing of treatment in a pre-clinical model of BPD...

Hereditary pulmonary alveolar proteinosis (herPAP) constitutes a rare, life threatening lung disease characterized by the inability of alveolar macrophages to clear the alveolar airspaces from surfactant phospholipids. On a molecular level, the disorder is defined by a defect in the CSF2RA gene coding for the GM-CSF receptor alpha-chain (CD116). As therapeutic options are limited, we currently pursue a cell and gene therapy approach aiming for the intrapulmonary transplantation of gene-corrected macrophages derived from herPAP-specific induced pluripotent stem cells (herPAP-iPSC) employing transcriptional activator-like effector nucleases (TALENs)...

BACKGROUND: Hypoxia preconditioning has been proven to be an effective method to enhance the therapeutic action of mesenchymal stem cells (MSCs). However, the beneficial effects of hypoxic MSCs in ischemia/reperfusion (I/R) lung injury have yet to be investigated. In this study, we hypothesized that the administration of hypoxic MSCs would have a positive therapeutic impact on I/R lung injury at molecular, cellular, and functional levels. METHODS: I/R lung injury was induced in isolated and perfused rat lungs...

OBJECTIVES: Mesenchymal stem cells-based therapies have shown promising effects in experimental acute respiratory distress syndrome. Different mesenchymal stem cells sources may result in diverse effects in respiratory diseases; however, there is no information regarding the best source of mesenchymal stem cells to treat pulmonary acute respiratory distress syndrome. We tested the hypothesis that mesenchymal stem cells derived from bone marrow, adipose tissue, and lung tissue would lead to different beneficial effects on lung and distal organ damage in experimental pulmonary acute respiratory distress syndrome...

Therapeutic strategies based on stem cells have been shown to have potential in improving the condition of severe lung diseases. In this study, the suppressive effects of conditioned medium (CM) of induced pluripotent stem cells (iPSCs) on pulmonary fibroblast differentiation were investigated in a series of in vitro and in vivo experiments. Moreover, the underlying mechanisms through which iPSC-CM inhibited the differentiation of fibroblasts into myofibroblasts were explored as well. iPSCs were generated using a mouse 3-gene transfection method, myofibroblast-like cells were induced by incubating human fibroblasts with transforming growth factor-β1 (TGF-β1) and mouse models of pulmonary fibrosis (PF) were established by an injection of bleomycin...

The present study aimed to assess the effects of therapy with adiponectin (APN) gene-modified adipose-derived stem cells (ADSCs) on pulmonary arterial hypertension (PAH) in rats and the underlying cellular and molecular mechanisms. ADSCs were successfully isolated from the rats and characterized. ADSCs were effectively infected with the green fluorescent protein (GFP)-empty (ADSCs-V) or the APN-GFP (ADSCs-APN) lentivirus and the APN expression was evaluated by ELISA. Sprague-Dawley rats were administered monocrotaline (MCT) to develop PAH...

Endothelin 1 (ET-1), mainly produced from vascular endothelial cells, induces vasoconstriction in physiological conditions. The endothelin receptor antagonist is among the most effective agents for pulmonary hypertension. However, little is known about the production source of ET-1 in inflammation and immunity. Here, we studied whether T cell-mediated ET-1 production system exists and operates independent of the production system in vascular endothelial cells. ET-1 production was readily detectable in the culture supernatant of human PBMCs and murine spleen cells stimulated with anti-CD3 antibody...

Adipose-derived stem cells (AdSCs) have recently been considered a useful treatment tool for autoimmune disease because of their anti-inflammatory and immunosuppressive effects. We investigated the therapeutic effect of intravenous AdSC transplantation in a mouse model of bleomycin-induced lung injury. AdSCs accumulated in the pulmonary interstitium and inhibited both inflammation and fibrosis in the lung, markedly improving the survival rate of mice with bleomycin-induced lung injury in a cell number-dependent manner...
