Pharmacokinetics of fluticasone propionate and salmeterol delivered as a combination dry powder via a capsule-based inhaler and a multi-dose inhaler

Conclusions SFC 50/250 μg Rotacaps/Rotahaler (L) showed comparable systemic exposure to Diskus in terms of FP AUC and SALM AUC and C max. These results merit further progression of SFC 50/250 μg Rotacaps/Rotahaler (L) to phase 3 clinical evaluation in asthma and COPD patients. The lack of pharmacokinetic comparability between the inhalers for SFC 50/100 μg requires further evaluation.

Authors: Zhao Z, Chang MY, Frerichs I, Zhang JH, Chang HT, Gow CH, Möller K Abstract BACKGROUND: Since bronchial abnormalities often exhibit spatial non-uniformity which may be not correctly assessed by conventional global lung function measures, regional information may help to characterize the disease progress. We hypothesized that regional air trapping during mechanical ventilation could be characterized by regional end-expiratory flow (EEF) derived from electrical impedance tomography (EIT). METHODS: Twenty-five patients suffering from chronic obstructive pulmonary disease (COPD grade 3 or 4) or severe...

ChungAbstractObjective: The purpose of the study is to investigate the risk of preventable hospitalization among patients with rheumatoid arthritis (RA).Methods: We identified 11,852 incident RA patients and 59,260 age-, sex-, and index year-matched controls from the Taiwan National Health Insurance Database. Index date was the RA diagnosis date for cases, which was assigned to their matched controls. The odds ratios (OR) of preventable hospitalizations between RA patients...

In this study, we report the design and fabrication of a high-performance HPV sensor based on nanocomposites of nanofibers of a porphyrin derivative (oxo-[5,10,15,20-tetra(4-pyridyl)porphyrinato]titanium(IV) (TiOTPyP)) and single-walled carbon nanotubes (SWCNTs) at room temperature. Two types of HPV sensor transducers were fabricated using pristine SWCNTs only and TiOTPyP nanofiber/SWCNT nanocomposite and the sensor responses were compared. The significant differences in reproducibility and selectivity of the two sensors reflected the significant impact of the added TiOTPyP nanofibers on the device performance. The respons...

Induced sputum is a non-invasive method of collecting cells from airways. Gene expression analysis from sputum cells has been used to understand the underlying mechanisms of airway diseases such as asthma or chronic obstructive pulmonary disease (COPD). Suitable reference genes for normalisation of target mRNA levels between sputum samples have not been defined so far. The current study assessed the expression stability of nine common reference genes in sputum samples from 14 healthy volunteers, 12 asthmatics and 12 COPD patients. Using three different algorithms (geNorm, NormFinder and BestKeeper), we identified HPRT1 and...

The recent paper in the European Respiratory Journal by Janson et al. [1] on testing bronchodilator responsiveness suggests that it has no value in distinguishing asthma from COPD. The authors correctly state that "there are many different ways of defining bronchodilator reversibility." However, they do not then mention any of them other than using the change in forced expiratory volume in 1 s (FEV1) standardised by the start value. This can lead to a sex and size bias in assessing bronchodilator response [2]. One method, that was recommended by the European Respiratory Society many years ago [3], standardises th...

Authors: Friedlander HM, Ford JA, Zaccardelli A, Terrio AV, Cho MH, Sparks JA Abstract Introduction: Smoking is an established risk factor for both lung diseases and rheumatoid arthritis (RA). Chronic mucosal airway inflammation may result in immune tolerance loss, neoantigen formation, and production of RA-related autoantibodies that increase the subsequent risk of RA. In this review, we aimed to summarize the current evidence supporting the role of obstructive lung diseases and subsequent risk of RA.Areas covered: We identified scientific articles discussing the biologic mechanisms linking mucosal airway inflamma...

COPD and asthma exacerbations are commonly triggered by rhinovirus infection. Potentially promoting exacerbations, impaired anti-viral signaling and attenuated viral clearance have been observed in diseased bronchial epithelium. Oxidative stress is a feature of inflammation in asthma and COPD and is prominent during exacerbations. It is not known whether oxidative stress affects the anti-viral signaling capacity. Bronchial epithelial cells from asthmatic and COPD donors were infected with rhinovirus or treated with the oxidative stressor H2O2 followed by exposure to the synthetic viral replication intermediate poly(I:C). P...

Purpose of review To provide an update on the implementation of precision medicine, based on treatable traits and mechanisms, in the daily clinical management of chronic airways diseases. Recent findings Recent insights into the complex and heterogeneous nature of chronic airway diseases including chronic obstructive pulmonary disease (COPD) and asthma identified several clinical and inflammatory phenotypes. This shifted the management focus of these diseases away from the prototypic disease labels and paved the way for developing novel targeted therapies. The concept of precision medicine aims to link the right pati...
