Mortality in interstitial lung disease: do race and skin colour matter?
In recent years, research surrounding health disparities has begun to focus more on the complex relationship between race, genetics and disease. Race has come to be recognised as an important factor, not only when discussing disparities and determining policy, but also in the diagnosis, approach and response to treatment.

The ageing brain in sleep apnoea: paradoxical resilience, survival of the fittest, or simply comparing apples and oranges?
The elevated prevalence of obstructive sleep apnoea (OSA) and its association with a long and ever expanding list of end-organ morbidities has prompted substantial interest in identifying mechanistic pathways underlying such deleterious consequences, and their potential reversibility with treatment. Over the last several decades, we have witnessed substantial increases in the granularity of the morbid phenotype of OSA, and such observations have prompted us to rethink some of the stricter early concepts. Among them, rather than viewing OSA as a single disease model that is applicable to all patients, we have formulated the...

A multi-organ loss of tissue phenotype in COPD: involvement of the functional muscle-bone unit
In the ECLIPSE (Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints) chronic obstructive pulmonary disease (COPD) cohort including 1817 men and women aged 40–75 years with full computed tomography (CT) data, Celli et al.  showed that emphysema progression was associated with loss of extrapulmonary tissues such as skeletal muscle and bone. I agree with the authors that identification of the patients they proposed to name a multi-organ loss of tissue (MOLT) COPD phenotype is important because of worse clinical outcomes  and would also like to point out that physical activity pla...

A harmonised European training syllabus for thoracic surgery: report from the ESTS/ERS task force group
As has been reported for respiratory medicine, a high variance exists among European countries in the content and modes of delivery for specialty training in thoracic surgery. According to a survey by the Union Européenne des Médecins Spécialistes (UEMS; European Union of Medical Specialists) section of thoracic surgery conducted in 2013, disparities begin at the certifying body level: the specialist diploma is delivered by the ministry of health in half of the countries, and by various other authorities in the remaining countries .

Survival of patients with schistosomiasis-associated pulmonary arterial hypertension in the modern management era
Pulmonary arterial hypertension (PAH) is a life-threatening disease characterised by an elevated pulmonary vascular resistance in the absence of left ventricular disease, and increasing pulmonary artery pressure, with consequent right ventricular failure and death . Several aetiologies have been associated with PAH, including connective tissue diseases, congenital heart diseases and chronic infections, such as HIV. Due to its high prevalence in developing countries, one of the most relevant forms of PAH worldwide is the one associated to schistosomiasis . (Source: European Respiratory Journal)

African-American race and mortality in interstitial lung disease: a multicentre propensity-matched analysis
We studied whether African-American race is associated with younger age and decreased survival time at diagnosis of interstitial lung disease (ILD). We performed a multicentre, propensity score-matched analysis of patients with an ILD diagnosis followed at five US hospitals between 2006 and 2016. African-Americans were matched with patients of other races based on a time-dependent propensity score calculated from multiple patient, physiological, diagnostic and hospital characteristics. Multivariable logistic regression models were used. All-cause mortality and hospitalisations were compared between race-stratified patient ...

Early experience with delamanid-containing regimens in the treatment of complicated multidrug-resistant tuberculosis in Hong Kong
Hong Kong is an intermediate tuberculosis (TB) burden region with a disease notification rate of 60.5 per 100 000 population in 2015. With the use of supervised treatment since 1970s and the use of drug susceptibility testing (DST) for guiding use of TB drugs for several decades , TB drug resistance rates in Hong Kong have declined and the multidrug-resistant (MDR)-TB rate has been kept at ~1%. Successful control of MDR-TB was partly attributable to judicious use of ofloxacin and later levofloxacin in the 1990s [2, 3], the introduction of linezolid in the 2000s  among patients with fluoroquinolone-resistant MDR-TB or...

Sleep apnoea in the asymptomatic elderly: a real issue for the brain?
The link between sleep apnoea and brain structure is unclear; although dysfunction of the hippocampus, middle temporal gyrus and brainstem/cerebellum have been observed previously. However, this link has been little explored in elderly subjects. The aim of this study was to explore the link between sleep apnoea and the brain in an elderly population. 226 asymptomatic elderly subjects (age mean±sd 75.3±0.9 years, range 72.3–77.8 years) from the PROOF (Evaluation of Ageing, Autonomic Nervous System Activity and Cardiovascular Events) cohort study were explored using linear voxel-based or cortical thi...

Is low level of vitamin D a marker of poor health, or a cause?
Vitamin D has long been recognised for its role in maintaining good skeletal health in both adults and children, including the rapid bone mineral accrual in infants, and prevention of rickets in children and osteomalacia in adults [1, 2]. Studies suggest that vitamin D, an essential hormone ingested from the diet (food and supplements) or synthesised in the skin when exposed to UV-B radiation, regulates calcium, phosphorous and bone metabolism, promotes skeletal muscle strength, inhibits cell proliferation, promotes cell differentiation, reduces inflammation, modulates the renin-angiotensin system, and influences glucose m...

Dysregulation of the "inflammatory reflex" with abnormal neurohumoral activation may contribute to proinflammatory activity driving the progression of COPD
We would like to thank S. Andreas for his interest in our study  and for the interesting comments. We agree with the insightful reasoning that subtle neurohormonal activation may be one of the explanations underlying the longitudinal association between subtle signs of cardiovascular autonomic dysfunction and higher risk of chronic obstructive pulmonary disease (COPD). In parallel to the findings in heart failure  and COPD , manifest clinical entities of cardiovascular autonomic dysfunction, such as orthostatic hypotension [4, 5] and postural orthostatic tachycardia syndrome , are all associated with clear...

The association of cardiovascular autonomic dysfunction and the prediction of COPD can be explained by neurohumoral activation
I read with great interest the recent work by Ricci et al.  published in the European Respiratory Journal. This insightful population-based study followed a very large cohort without baseline airflow obstruction for 32 years. Interestingly, baseline orthostatic blood pressure decrease, as well as increased resting heart rate, was associated with reduced lung function during follow-up. The authors consequently suggested that subtle signs of cardiovascular autonomic dysfunction may precede the development of chronic obstructive pulmonary disease (COPD).

Risk factors for lung disease progression in children with cystic fibrosis
To identify potential risk factors for lung disease progression in children with cystic fibrosis (CF), we studied the longitudinal data of all children with CF (aged ≥5 years) registered in the Dutch CF Registry (2009–2014). Lung disease progression was expressed as a decline in lung function (forced expiratory volume in 1 s (FEV1) % pred) and pulmonary exacerbation rate. Potential risk factors at baseline included sex, age, best FEV1 % pred, best forced vital capacity % pred, genotype, body mass index z-score, pancreatic insufficiency, medication use (proton pump inhibitors (PPIs), prophylactic antibiot...

In this issue of the European Respiratory Journal, Otsuki et al.  postulate that antibody targeting of aminopeptidase N (APN)/CD13 by MT95-4 might be a potential therapeutic approach for malignant pleural mesothelioma (MPM). Aminopeptidases have several functions, but their main role is breakdown of small peptides . However, aminopeptidases may also play a role in angiogenesis. Angiogenesis signalling is an important hallmark of solid cancer pathophysiology in general and MPM in particular . Several mechanisms are involved in this process; one of the most important factors is the shedding by the tumour of the liga...

Haemodynamic profiling of group 2 pulmonary hypertension (PH) is constantly evolving, and poses a number of challenges in terms of diagnosis and staging . Given that the haemodynamic signature of left-sided PH is the increased pulmonary arterial wedge pressure (PAWP) at rest (>15 mmHg) with a mean pulmonary arterial pressure (mPAP) ≥25 mmHg, some diagnostic uncertainty may occur when mPAP is elevated in the presence of a non-dilated left ventricular (LV) chamber with preserved LV ejection fraction and a PAWP at rest within the upper normal limit (range 12–15 mmHg) .

In-depth haemodynamic phenotyping of pulmonary hypertension due to left heart disease
The commonest cause of pulmonary hypertension (PH) is left heart disease (LHD). The current classification system for definitions of PH-LHD is under review. We therefore performed prospective in-depth invasive haemodynamic phenotyping in order to assess the site of increased pulmonary vascular resistance (PVR) in PH-LHD subsets. Based on pulmonary artery occlusion waveforms yielding an estimate of the effective capillary pressure, we partitioned PVR in larger arterial (Rup, upstream resistance) and small arterial plus venous components (Rds, downstream resistance). In the case of small vessel disease, Rup decreases and Rds...

Angiogenesis is a crucial factor in the progression of malignant pleural mesothelioma (MPM) and antiangiogenic strategies might be effective against MPM. Aminopeptidase N (APN)/CD13 promotes tumour angiogenesis and is associated with poor prognosis; however, its clinical significance in MPM remains unclear. In 37 consecutive patients with surgically resected MPM, we evaluated the association between immunohistochemical APN/CD13 expression in resected tumours and survival. Additionally, the antitumour and antiangiogenic effects of MT95-4, a fully humanised anti-APN/CD13 monoclonal antibody, were evaluated in mice orthotopic...

Cured bronchi! Extending the use of nebulised hypertonic saline outside of cystic fibrosis?
Plugging of the airways by excessive mucus is an important contributor to morbidity and mortality in chronic airway diseases (e.g. cystic fibrosis (CF), chronic obstructive pulmonary disease (COPD), bronchiectasis and primary ciliary dyskinesia (PCD)) . Such findings are the basis for the major interest in drugs that reduce mucus content in airways by targeting mucus production  or by increasing clearance of mucus . A single aerosol of hypertonic saline (HS) was shown to enhance clearance of airway secretions in humans>40 years ago , and a randomised control trial reported>10 years ago found tha...

What's in a name? That which we call IPF, by any other name would act the same
Idiopathic pulmonary fibrosis (IPF) remains a truly idiopathic fibrotic disease, with a modest genetic predilection and candidate triggers but no overall explanation for the development of disease in non-familial cases. Agreement on terminology has contributed to major clinical and translational advances since the millennium. It is likely that the entity currently captured by the term "IPF" will be radically reclassified over the next decade, either through "splitting" (into IPF subgroups responding selectively to individual disease-modifying agents) or through "lumping" of IPF with other form...

Cough sensitivity to mannitol inhalation challenge identifies subjects with chronic cough
Cough is the most common reason why people seek medical attention . Cough hypersensitivity syndrome (CHS) is a new concept to describe a condition with long-standing hypersensitivity of vagal afferent nerves or an alteration of the central processing of their input regardless of the underlying cause . The current definition of CHS is purely clinical; however, a test capable of demonstrating this hypersensitivity both reliably and feasibly might be used as a diagnostic test for CHS.

The clinical significance of oropharyngeal cultures in young children with cystic fibrosis
In children with cystic fibrosis (CF) the associations between oropharyngeal swabs (OPSs) for detection of Pseudomonas and lung disease have not been evaluated. OPS and bronchoalveolar lavage (BAL) samples were obtained annually in children with CF from 2005 to 2017. OPS test characteristics were calculated using BAL as "gold standard". Results were related to lung inflammation (BAL neutrophil elastase and interleukin-8), structural lung disease (chest computed tomography PRAGMA-CF (Perth–Rotterdam Annotated Grid Morphometric Analysis for CF) scores), respiratory exacerbations and future detection of Pseudo...

Lung cancer staging: a concise update
Diagnosis and clinical staging of lung cancer are fundamental to planning therapy. The techniques for clinical staging, i.e. anatomic and metabolic imaging, endoscopies and minimally invasive surgical procedures, should be performed sequentially and with an increasing degree of invasiveness. Intraoperative staging, assessing the magnitude of the primary tumour, the involved structures, and the loco-regional lymphatic spread by means of systematic nodal dissection, is essential in order to achieve a complete resection. In resected tumours, pathological staging, with the systematic study of the resected specimens, is the str...

Gadofosveset-enhanced lung magnetic resonance imaging to detect ongoing vascular leak in pulmonary fibrosis
Vascular leak is a cardinal response to tissue injury [1, 2]. When dysregulated, vascular leak has been shown to contribute to the development of pulmonary fibrosis in the bleomycin mouse model . Specifically targeting vascular endothelial growth factor, initially described as vascular permeability factor  and a key mediator regulating capillary permeability, attenuates the development of pulmonary fibrosis in vivo . Gadofosveset (Ablavar; Lantheus Medical Imaging Inc., North Billerica, MA, USA) is a US Food and Drug Administration-approved, gadolinium-based, albumin-binding contrast agent. Gadofosveset has been u...

ERS/ECDC Statement: European Union standards for tuberculosis care, 2017 update
The International Standards for Tuberculosis Care define the essential level of care for managing patients who have or are presumed to have tuberculosis, or are at increased risk of developing the disease. The resources and capacity in the European Union (EU) and the European Economic Area permit higher standards of care to secure quality and timely TB diagnosis, prevention and treatment. On this basis, the European Union Standards for Tuberculosis Care (ESTC) were published in 2012 as standards specifically tailored to the EU setting. Since the publication of the ESTC, new scientific evidence has become available and, the...

The in vitro effect of nebulised hypertonic saline on human bronchial epithelium
Inhaled hypertonic saline (HS) is an effective therapy for muco-obstructive lung diseases. However, the mechanism of action and principles pertinent to HS administration remain unclear. An in vitro system aerosolised HS to epithelial cells at rates comparable to in vivo conditions. Airway surface liquid (ASL) volume and cell height responses were measured by confocal microscopy under normal and hyperconcentrated mucus states. Aerosolised HS produced a rapid increase in ASL height and decrease in cell height. Added ASL volume was quickly reabsorbed following termination of nebulisation, although cell height did not recover ...

Meta-analysis of airway epithelium gene expression in asthma
Differential gene expression in the airway epithelium of patients with asthma versus controls has been reported in several studies. However, there is no consensus on which genes are reproducibly affected in asthma. We sought to identify a consensus list of differentially expressed genes (DEGs) using a meta-analysis approach. We identified eight studies with data that met defined inclusion criteria. These studies comprised 355 cases and 193 controls and involved sampling either bronchial or nasal epithelium. We conducted study-level analyses, followed by a meta-analysis. Likewise, we applied a meta-analysis framework to the...

Are peripheral blood eosinophil counts a guideline for omalizumab treatment? STELLAIR says no!
Biologics for the treatment of severe asthma are assuming an ever expanding and important role to gain disease control when current therapeutics are not effective [1, 2]. Although the number of asthma patients with severe disease is relatively small, 10–15%, when compared to the overall prevalence of asthma, the burden of disease in this group is large from many perspectives including compromises to lifestyle, risks for recurrent and severe exacerbations, hospitalisations, unscheduled care needs, potential for adverse effects from medications, and medical costs. Therefore, severe asthma carries a dominant disease bur...
