Coexistent Sarcoidosis and Tuberculosis: A Case Report
We report a case of bilateral tuberculous pleurisy in a 45-year-old male native of a North-African region with an atypical severe multisystem disease characterized by a fever resistant to anti-TB therapy and respondent to corticosteroid treatment. The choice to continue both steroid and anti-TB therapy proved to be correct for the late evidence of TB mycobacterial growth only on pleural specimens. The case described is suggestive of a coexistent systemic sarcoid manifestation and low-antigen TB, which is an underrecognized entity in the medical literature.Respiration (Source: Respiration)

[Favipiravir, a new concept of antiviral drug against influenza viruses].
Abstract Favipiravir (T-705) is a new antiviral drug with strong inhibitory activity on RNA-dependent RNA polymerase of most RNA virus genome. All the influenza viruses have been shown fully sensitive to this new antiviral, including genetic strains to neuraminidase inhibitors (oseltamivir) resistance. Its mechanism of action lies in blocking viral replication and induction of lethal mutagenesis which determines the loss of infective activity of influenza viruses. Its activity is particularly intense in the respiratory tract, decreasing the viral load to non-infectious levels. Clinical trials in humans have not ye...

Imidazoline 1 receptor activation preserves respiratory drive in spontaneously breathing newborn rats during dexmedetomidine administration.
CONCLUSIONS: Our results suggest that in newborn rats undergoing dexmedetomidine sedation, the α2 -adrenoceptor, but not I1 receptor, is involved in the regulation of HR and respiratory frequency, and that activation of the I1 receptor plays a major role in the maintenance of respiratory drive.

Hypoxia and aerobic metabolism adaptations of human endothelial cells.
Abstract The goal of our study was to assess the influence of chronic exposure to hypoxia on mitochondrial oxidative metabolism in human umbilical vein endothelial cells (EA.hy926 line) cultured for 6 days at 1% O2 tension. The hypoxia-induced effects were elucidated at the cellular and isolated mitochondria levels. Hypoxia elevated fermentation but did not change mitochondrial biogenesis or the aerobic respiratory capacity of endothelial cells. In endothelial cells, hypoxia caused a general decrease in mitochondrial respiration during carbohydrate, fatty acid, and amino acid oxidation but increased exclusively k...

Renin-angiotensin-aldosterone system inhibitors improve membrane stability and change gene-expression profiles in dystrophic skeletal muscles
Angiotensin-converting enzyme inhibitors (ACEi) and mineralocorticoid receptor (MR) antagonists are FDA-approved drugs that inhibit the renin-angiotensin-aldosterone system (RAAS) and are used to treat heart failure. Combined treatment with the ACEi lisinopril and the nonspecific MR antagonist spironolactone surprisingly improves skeletal muscle, in addition to heart function and pathology in a Duchenne muscular dystrophy (DMD) mouse model. We recently demonstrated that MR is present in all limb and respiratory muscles and functions as a steroid hormone receptor in differentiated normal human skeletal muscle fibers. The go...

Nonadherence to the medical regimen after lung transplantation: A systematic review
This study reports on the first systematic review focused on lung transplant recipients (LTRs) and provides evidence regarding 1) prevalence of nonadherence to the post-transplant medical regimen; 2) risk factors for nonadherence; 3) impact of adherence-promoting interventions; and 4) transplant-related clinical outcomes of nonadherence in LTRs. Following the PRISMA guidelines, a literature search of 5 databases was conducted, yielding 30 relevant articles. Findings suggested that nonadherence rates varied greatly across regimen components and were not consistently associated with any single risk factor. Effect sizes in t...

The search for the hypersensitivity in chronic cough
Chronic cough is a common disorder that affects an estimated 10% of the general population . Adverse symptoms such as urinary incontinence, chest pains, headaches and syncope are frequently associated with cough and lead to poor health-related quality of life [2, 3]. Chronic cough has long been viewed as a symptom of other chronic disorders, hence the current approach to assessing and treating patients focuses on identifying an underlying condition, such as asthma and gastro-oesophageal reflux disease . A significant number of cases of chronic cough, as many as 50%, remain unexplained following detailed assessment. T...

Severe asthma: phenotyping to endotyping or vice versa?
The most recent definition of asthma is that it is a heterogeneous disease, usually characterised by chronic airway inflammation, defined by a history of chronic respiratory symptoms that vary over time, both in frequency and intensity, and associated with variable airflow limitation . Admittedly, asthma is used as an umbrella term, like anaemia, arthritis and cancer. This highlights the importance of taking an individualised approach to a patient's diagnosis and management, using genomics, proteomics, and "humanomics" as emphasised in the GINA guidelines . The vague definition reflects our poor understanding of the ...

Awareness of predictors of mortality may help improve outcome in chronic pulmonary aspergillosis
Chronic pulmonary aspergillosis (CPA) is a severe fungal infection usually seen in immunocompetent patients with underlying respiratory disorders . Estimates suggest that ~3 million people suffer from CPA globally . The precise prevalence is unknown. Pulmonary tuberculosis (TB) seems to be the most relevant driver for the global burden of CPA with estimates suggesting about 1.2 million patients with CPA as a sequel to TB . Given that there were 10.4 million new TB cases in 2015, CPA represents a serious sequela to pulmonary TB . However, any search for CPA in the Global Tuberculosis Report of the World Hea...

A new two-step algorithm for the treatment of COPD
The pharmacological treatment of chronic obstructive pulmonary disease (COPD) is quite uniformly based on long-acting bronchodilators (LABD), either a long-acting muscarinic antagonist (LAMA) or a long-acting β-agonist (LABA), and inhaled corticosteroids (ICS). Moreover, most patients are eventually treated with a combination of all three (LAMA/LABA/ICS or "triple therapy") irrespective of their severity and level of risk. Furthermore, a large proportion of patients receive triple therapy as the initial treatment . We propose a new simple treatment algorithm based on the severity of symptoms and phenotypes or treat...

T-helper cell type 2 (Th2) and non-Th2 molecular phenotypes of asthma using sputum transcriptomics in U-BIOPRED
Asthma is characterised by heterogeneous clinical phenotypes. Our objective was to determine molecular phenotypes of asthma by analysing sputum cell transcriptomics from 104 moderate-to-severe asthmatic subjects and 16 nonasthmatic subjects. After filtering on the differentially expressed genes between eosinophil- and noneosinophil-associated sputum inflammation, we used unbiased hierarchical clustering on 508 differentially expressed genes and gene set variation analysis of specific gene sets. We defined three transcriptome-associated clusters (TACs): TAC1 (characterised by immune receptors IL33R, CCR3 and TSLPR), TAC2 (c...

Paper acceptance time in respiratory research: room for improvement?
We recently submitted a paper to a top five respiratory journal in terms of average citations per article. The paper was swiftly sent for peer review. A month later, the review was in, and the paper was now "awaiting associate editor decision". After another 6 weeks, and at the time of writing this letter, the paper is still with the handling editor. Like us, many authors have probably at this stage speculated when it would be reasonable to contact the editorial office and enquire about the status. (Source: European Respiratory Journal)

Tussive challenge with ATP and AMP: does it reveal cough hypersensitivity?
Recent studies have demonstrated that blockade of P2X3 ATP receptors can profoundly inhibit chronic cough. We have considered whether inhaled ATP produces a tussive response and whether chronic cough patients are hypersensitive to inhaled ATP compared to healthy volunteers. A standardised inhalational cough challenge was performed with ATP and AMP. We randomised 20 healthy volunteers and 20 chronic cough patients as to the order of challenges. The concentration of challenge solution causing at least five coughs (C5) was compared for ATP and AMP. The study population consisted of six male and 14 female volunteers in each gr...

Predictors of mortality in chronic pulmonary aspergillosis
Chronic pulmonary aspergillosis (CPA) is a chronic progressive infection that destroys lung tissue in non-immunocompromised patients. Contemporary series suggest 50–85% 5-year mortality, with few prognostic factors identified. A cohort of 387 CPA patients referred to the UK's National Aspergillosis Centre from 1992 to June 2012 was studied until June 2015. The impact of objective and subjective variables including age, sex, previous pulmonary conditions, dyspnoea score, quality of life, serum albumin and C-reactive protein and radiological appearances were assessed using Kaplan–Meier curves, log rank tests and ...

Standardisation and application of the single-breath determination of nitric oxide uptake in the lung
Diffusing capacity of the lung for nitric oxide (DLNO), otherwise known as the transfer factor, was first measured in 1983. This document standardises the technique and application of single-breath DLNO. This panel agrees that 1) pulmonary function systems should allow for mixing and measurement of both nitric oxide (NO) and carbon monoxide (CO) gases directly from an inspiratory reservoir just before use, with expired concentrations measured from an alveolar "collection" or continuously sampled via rapid gas analysers; 2) breath-hold time should be 10 s with chemiluminescence NO analysers, or 4–6 s to acco...

Depletion of circulating monocytes suppresses IL-17 and HMGB1 expression in mice with LPS-induced acute lung injury
Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is an important cause of mortality in critically ill patients. Macrophages play an important role in the pathogenesis of ALI/ARDS. To investigate the role and underlying mechanisms of circulating monocytes and resident alveolar macrophages (AMs) in ALI/ARDS, we depleted circulating monocytes and AMs by clodronate-loaded liposome (CL) in a lipopolysaccharide (LPS)-induced ALI/ARDS mouse model. Our results indicated that depletion of circulating monocytes by intravenous injection of CL 2 days before intratracheal LPS treatment significantly suppressed the acute...

Radial endobronchial ultrasound for the diagnosis of peripheral pulmonary lesions: A systematic review and meta ‐analysis
ABSTRACT Tissue diagnosis of peripheral pulmonary lesions (PPLs) can be challenging. In the past, flexible bronchoscopy was commonly performed for this purpose but its diagnostic yield is suboptimal. This has led to the development of new bronchoscopic modalities such as radial endobronchial ultrasound (R‐EBUS), electromagnetic navigation bronchoscopy (ENB) and virtual bronchoscopy (VB). We performed this meta‐analysis using data from previously published R‐EBUS studies, to determine its diagnostic yield and other performance characteristics.

Measurement of the Raman spectra and hygroscopicity of four pharmaceutical aerosols as they travel from pressurised metered dose inhalers (pMDI) to a model lung
Publication date: 30 March 2017 Source:International Journal of Pharmaceutics, Volume 520, Issues 1–2 Author(s): N. Davidson, H.-J. Tong, M. Kalberer, P.C. Seville, A.D. Ward, M.K. Kuimova, F.D. Pope Particle inhalation is an effective and rapid delivery method for a variety of pharmaceuticals, particularly bronchodilation drugs used for treating asthma and COPD. Conditions of relative humidity and temperature inside the lungs are generally very different from the outside ambient air, with the lung typically being warmer and more humid. Changes in humidity, from inhaler to lung, can cause hygroscopic phase transitions a...
