AZD5423 is a novel, inhaled, selective glucocorticoid receptor modulator (SGRM), which in an allergen challenge model in asthmatics improved lung function and airway hyper-reactivity. In the current trial, AZD5423 was for the first time tested in patients with chronic obstructive pulmonary disease (COPD). In this double-blind, randomised and parallel group study, we examined airway and systemic effects of two doses of AZD5423, inhaled via Turbuhaler for 12 weeks, in 353 symptomatic COPD patients (average pre-bronchodilator forced expiratory volume in one second (FEV1) at screening was 50-52% of predicted normal)...

PURPOSE OF REVIEW: Exacerbations of bronchiectasis have a major impact on quality of life, healthcare costs, and long-term risk of complications. Preventing exacerbations is one of the major goals of treatment. Bronchiectasis is increasingly recognized and the impact of bronchiectasis exacerbations on daily clinical practice is also increasing. RECENT FINDINGS: Preventing bronchiectasis exacerbations are dependent on appropriate risk assessment, identifying the patients at highest risk to rationally target preventive therapies...

T1 maps have been shown to yield useful diagnostic information on lung function in patients with chronic obstructive pulmonary disease (COPD) and asthma, both for native T1 and ΔT1, the relative reduction while breathing pure oxygen. As parameter quantification is particularly interesting for longitudinal studies, the purpose of this work was both to examine the reproducibility of lung T1 mapping and to compare T1 found in COPD and asthma patients using IRSnapShotFLASH embedded in a full MRI protocol. 12 asthma and 12 COPD patients (site 1) and further 15 COPD patients (site 2) were examined on two consecutive days...

PURPOSE: Recent pulmonary imaging research has revealed that in patients with chronic obstructive pulmonary disease (COPD) and asthma, structural and functional abnormalities are spatially heterogeneous. This novel information may help optimize treatment in individual patients, monitor interventional efficacy and develop new treatments. Moreover, by automating the measurement of regional biomarkers for the 19 different anatomical lung segments, there is an opportunity to embed imaging biomarkers into clinically-acceptable clinical workflows and improve lung disease clinical care...

Many patients with chronic obstructive pulmonary disease (COPD) receive inhaled corticosteroids (ICSs) without a clear indication, and thus, the impact of ICS withdrawal on disease control is of great interest. DACCORD is a prospective, noninterventional 2-year study in the primary and secondary care throughout Germany. A subgroup of patients were taking ICS prior to entry - 1,022 patients continued to receive ICS for 2 years; physicians withdrew ICS on entry in 236 patients. Data from these two subgroups were analyzed to evaluate the impact of ICS withdrawal...

Chronic respiratory diseases affect millions of people every day. According to World Health Organization estimates, ~235 million people suffer from asthma, ~64 million suffer from chronic obstructive pulmonary disease (COPD), and millions more suffer from allergic rhinitis around the world. In recent last years, the first phosphodiesterase 4 (PDE4) inhibitor, roflumilast, was approved as a treatment to reduce the risk of exacerbations in stable and severe COPD associated with chronic bronchitis and a history of exacerbations...

In this study, a series of pyrazole derivatives containing 4-phenyl-2-oxazole moiety were designed and synthesized in a concise way, some of which exhibited considerable inhibitory activity against PDE4B and blockade of LPS-induced TNF-α release. Compound 4c displayed the strongest inhibition activity (IC50=1.6±0.4μM) and good selectivity against PDE4B. Meanwhile, compound 4c showed good in vivo activity in animal models of asthma/COPD and sepsis induced by LPS. The primary structure-activity relationship study showed the 3,5-dimethylpyrazole residue was essential for the bioactivity, and the substituted group R1 at the benzene ring also affected the activity...

Adult bronchial asthma is characterized by chronic airway inflammation, and presents clinically with variable airway narrowing (wheezes and dyspnea) and cough. Long-standing asthma induces airway remodeling, leading to intractable asthma. The number of patients with asthma has increased; however, the number of patients who die of asthma has decreased (1.2 per 100,000 patients in 2015). The goal of asthma treatment is to enable patients with asthma to attain normal pulmonary function and lead a normal life, without any symptoms...

: Pneumocystis jirovecii can colonize patients with chronic obstructive pulmonary disease. To determine if colonization occurs in asthma patients, sputum samples from 10 patients with mild asthma, who were not receiving oral corticosteroids, were evaluated by a sensitive real-time PCR assay that targets a multicopy gene of P. jirovecii. 2 patients (20%) had Pneumocystis DNA detected; 1 patient had 3 positive samples over an 11-day period. Thus, Pneumocystis colonization occurs in asthma patients, and further studies are warranted to evaluate its role in airways disease...

Cigarette smoking is higher among low-income adults and individuals who reside in federally assisted housing are particularly susceptible to the adverse effects of smoking and secondhand smoke exposure. This study assessed smoking-related behaviors and health outcomes among U.S. adults who received federal housing assistance during 2006-2012. National Health Interview Survey data linked with administrative data from the U.S. Department of Housing and Urban Development were analyzed; 5218 HUD-assisted adults were assessed...

The incidence and prevalence of fungal infections in Chile are unknown. Here, we have estimated the burden of serious fungal diseases from data obtained from clinical reports, WHO reports, Chilean census, OECD reports and comprehensive literature search available on PubMed and SciELO, among other scientific resources. Due the lack of official data about fungal diseases, frequencies were calculated based on the specific populations at risk. Recurrent vulvovaginal candidiasis (>4 episodes/year) is estimated to occur in 3108/100,000...

There is a lack of knowledge on the epidemiology of fungal infections worldwide because there are no reporting obligations. The aim of this study was to estimate the burden of fungal disease in Portugal as part of a global fungal burden project. Most published epidemiology papers reporting fungal infection rates from Portugal were identified. Where no data existed, specific populations at risk and fungal infection frequencies in those populations were used in order to estimate national incidence or prevalence, depending on the condition...

Epidemiological data about mycotic diseases are limited in Peru and estimation of the fungal burden has not been previously attempted. Data were obtained from the Peruvian National Institute of Statistics and Informatics, UNAIDS and from the Ministry of Health's publications. We also searched the bibliography for Peruvian data on mycotic diseases, asthma, COPD, cancer and transplants. Incidence or prevalence for each fungal disease were estimated in specific populations at risk. The Peruvian population for 2015 was 31,151,543...

BACKGROUND: Obstructive sleep apnoea is a common disorder with under-rated clinical impact, which is increasingly being recognised as having a major bearing on global disease burden. Men are especially vulnerable and become a priority group for preventative interventions. However, there is limited information on prevalence of the condition in Australia, its co-morbidities, and potential risk factors. METHODS: We used data from 13,423 adult men included in the baseline wave of Ten to Men, an Australian national study of the health of males, assembled using stratified cluster sampling with oversampling from rural and regional areas...

BACKGROUND: Despite the proof of principle that gene therapy can cure various monogenic diseases, limited clinical progress has been noted for gene therapy of the respiratory system. Certain anatomic features of the lungs, along with the suboptimal gene delivery vehicles utilized up to now, have significantly delayed successful clinical practice. Thus, the need for additional improvements towards safety and efficacy of the procedure is indispensable. OBJECTIVE: The objective of this work was to review the progress and limitations of gene therapy in the treatment of lung disease with a focus on monogenic disease, chronic obstructive pulmonary disease and asthma and to present studies that provide a proof of principle that it works in different model systems and in patients...

Patients with difficult-to-manage asthma represent a heterogeneous subgroup of asthma patients who require extensive assessment and tailored management. The International Primary Care Respiratory Group approach emphasises the importance of differentiating patients with asthma that is difficult to manage from those with severe disease. Local adaptation of this approach, however, is required to ensure an appropriate strategy for implementation in the Dutch context. We used a modified three-round e-Delphi approach to assess the opinion of all relevant stakeholders (general practitioners, pulmonologists, practice nurses, pulmonary nurses and people with asthma)...

Right middle lobe (RML) syndrome is defined as recurrent or chronic obstruction or infection of the middle lobe of the right lung. Nonobstructive causes of middle lobe syndrome include inflammatory processes and defects in the bronchial anatomy and collateral ventilation. We report on 2 case patients with RML syndrome, one due to infection with Mycobacterium avium complex followed by M asiaticum infection and the other due to allergic bronchopulmonary aspergillosis. A history of atopy, asthma, or chronic obstructive pulmonary disease has been reported in up to one-half of those with RML...
