A Whitney Brown, Steven D Nathan
The 6 minute walk test (6MWT) is a commonly employed assessment of performance ability in a variety of cardiopulmonary diseases. It provides important functional information that is not captured in standardized pulmonary function testing. The test may be influenced by factors other than the severity of lung disease, including frailty, deconditioning, and musculoskeletal issues. The primary output measure from the six minute walk test is the distance walked, which appears to confer prognostic information in many diverse disease states...

Idiopathic pulmonary fibrosis (IPF) is a challenging and multifactorial disease that has been thought for some time to lack effective treatments. The approval of two drugs, nintedanib and pirfenidone, has heralded a new era in its management. Areas covered: Currently, there is a growing interest on therapeutic strategies. Many studies have been designed and performed, although few of them turned out to be successful. Nowadays, nintedanib and pirfenidone are considered disease modifying drugs, recommended treatments by current evidence-based guidelines...

REVIEW
Christian Benden
Pediatric lung transplantation has been undertaken since the 1980s, and it is today considered an accepted therapy option in carefully selected children with end-stage pulmonary diseases, providing carefully selected children a net survival benefit and improved health-related quality of life. Nowadays, >100 pediatric lung transplants are done worldwide every year. Here, specific pediatric aspects of lung transplantation are reviewed such as the surgical challenge, effects of immunosuppression on the developing pediatric immune system, and typical infections of childhood, as it is vital to comprehend that children undergoing lung transplants present a real challenge as children are not 'just small adults'...

BACKGROUND: Interstitial lung disease (ILD) is a disease with high mortality worldwide. Unfortunately, its prognosis is still very poor. Therefore, developing the target molecular is very important for ILD diagnosis and treatment. Caveolin-1 (Cav-1) can regulate the formation of fibrosis by linking to the signaling pathway of transforming growth factor-β1 (TGF-β1), which is generally considered to be the most effective approach to solve the problem of ILD. METHODS: The rat model of ILD was induced by disposable transtracheal injection of bleomycin hydrochloride...

Idiopathic pulmonary fibrosis is a progressive, fatal lung disease with poor survival. The advances made in deciphering this disease have led to the approval of different antifibrotic molecules, such as pirfenidone and nintedanib. An increasing number of studies with particles (liposomes, nanoparticles [NPs], microspheres, nanopolymersomes, and nanoliposomes) modified with different functional groups have demonstrated improvement in lung-targeted drug delivery. In the present study, we prepared, characterized, and evaluated spermidine (Spd)-modified poly(lactic-co-glycolic acid) (PLGA) NPs as carriers for fluorofenidone (AKF) to improve the antifibrotic efficacy of this drug in the lung...

BACKGROUND: Radiation therapy is commonly used to treat thoracic malignancies. However, it may lead to severe lung pneumonitis and ultimately fibrosis. Irradiation has been reported to increase epithelial-mesenchymal transition (EMT) of type II alveolar epithelial cells (AEC), which play an important role in pulmonary fibrosis. The transforming growth factor-β (TGF-β) and ERK/glycogen synthase kinase 3β (GSK3β) pathways are critically involved in radiation-induced EMT. In the present study, we investigated whether baicalin was a novel therapeutic candidate for radiation-induced EMT in type II AEC...

OBJECTIVES: To retrospectively investigate whether the baseline extent and 1-year change in regional disease patterns on CT can predict survival of patients with idiopathic pulmonary fibrosis (IPF). METHODS: A total of 144 IPF patients with CT scans at the time of diagnosis and 1 year later were included. The extents of five regional disease patterns were quantified using an in-house texture-based automated system. The fibrosis score was defined as the sum of the extent of honeycombing and reticular opacity...

BACKGROUND AND OBJECTIVE: Interstitial lung disease (ILD) is a common pulmonary manifestation of systemic sclerosis (SSc). It is unknown whether radiographic fibrosis score predicts mortality in SSc-associated ILD (SSc-ILD). We retrospectively analysed patients with SSc-ILD to evaluate whether radiographic fibrosis score was a useful predictor of mortality. METHODS: We identified SSc-ILD patients evaluated at Kurashiki Central Hospital (Japan) from 2006 to 2016, and radiographic fibrosis scores based on the extent of reticulation and honeycombing on high-resolution computed tomography (HRCT) scanning were calculated by manually tracing around each fibrotic area...

Dyskeratosis congenita (DC) is a rare, inherited, bone marrow failure syndrome caused by premature telomere shortening. The classic mucocutaneous triad of clinical features comprises reticulated skin pigmentation, nail dysplasia, and oral leukoplakia. Multiple somatic features, including bone marrow failure, pulmonary fibrosis, and liver disease, are also common. DC significantly increases the risk for malignant transformation, including myelodysplastic syndrome, acute myeloid leukemia, head and neck squamous cell carcinoma, and anogenital cancer...

BACKGROUND: Cough can be a debilitating symptom of idiopathic pulmonary fibrosis (IPF) and is difficult to treat. PA101 is a novel formulation of sodium cromoglicate delivered via a high-efficiency eFlow nebuliser that achieves significantly higher drug deposition in the lung compared with the existing formulations. We aimed to test the efficacy and safety of inhaled PA101 in patients with IPF and chronic cough and, to explore the antitussive mechanism of PA101, patients with chronic idiopathic cough (CIC) were also studied...

Interstitial lung disease (ILD) is a major pulmonary manifestation of connective tissue disease (CTD), leading to significant morbidity and mortality. Chest high-resolution computed tomography (HRCT) is presently considered the diagnostic gold standard for pulmonary fibrosis diagnosis and quantification in the clinical arena. However, not negligible doses of ionizing radiation limit the use of HRCT, especially for serial follow-up in younger female patients. In the past decade, lung ultrasound (LUS) has been proposed to assess ILD by detecting and quantifying sonographic B-lines...

BACKGROUND: Dysfunction in cystic fibrosis transmembrane conductance regulator (CFTR) can be elicited by cigarette smoke and is observed in patients with chronic bronchitis. We have previously demonstrated in human airway epithelial cell monolayers that roflumilast, a clinically approved phosphodiesterase 4 inhibitor that reduces the risk of exacerbations in chronic obstructive pulmonary disease patients with chronic bronchitis and a history of exacerbations, activates CFTR-dependent chloride secretion via a cAMP-mediated pathway, partially restores the detrimental effects of cigarette smoke on CFTR-mediated ion transport, and increases CFTR-dependent gastrointestinal fluid secretion in isolated murine intestine segments...

Fibroblast is believed to be the primary effector in idiopathic pulmonary fibrosis (IPF), a progressive lung disorder characterized by aberrant tissue remodeling and the formation of fibroblastic foci. Due to the complicated etiology and mechanism, there are few effective drugs for this fatal disease. Shikonin (SHI), which is the major ingredient isolated from the plant Lithospermum Erythrorhizon, has long been used as traditional medicine for many diseases including inflammation and cancer. The roles of SHI in attenuating skin scar and renal fibrosis by reducing TGFβ1-stimulated fibroblast activation are also reported...

OBJECTIVE: Serum immunoglobulin (Ig) G4 elevation has been associated with several pathological conditions other than IgG4-related disease (IgG4-RD). In cystic fibrosis (CF), an elevation of specific IgG4 has been associated with colonization and infection by Pseudomonas aeruginosa. IgG4 elevation may be a marker of chronic infection or inflammatory stimulation. The aim of this study was to explore the prevalence of elevated IgG4 levels in CF and its correlation with the major clinical and microbiological features found in CF patients...

Pirfenidone is known to slow the decline in vital capacity and increase survival in idiopathic pulmonary fibrosis (IPF). Besides, administration of glucocorticoids, e.g., prednisolone has been the conventional strategy to the treatment of patients with this disease, although their efficacy is under debate. Since multiple coactivated pathways are involved in the pathogenesis of IPF, combination therapy is a foundation strategy to cover many more synergetic mechanisms and increase response. The aim of the present study was to compare the therapeutic efficacy of prednisolone plus pirfenidone with pirfenidone alone in PQ-induced lung fibrosis...
