PURPOSE: The ability of two semi-mechanistic simulation approaches to predict the systemic pharmacokinetics (PK) of inhaled corticosteroids (ICSs) delivered via dry powder inhalers (DPIs) was assessed for mometasone furoate, budesonide and fluticasone propionate. METHODS: Both approaches derived the total lung doses and the central to peripheral lung deposition ratios from clinically relevant cascade impactor studies, but differed in the way the pulmonary absorption rate was derived...

OBJECTIVE: To systematically review the literature and determine frequencies of adverse drug events (ADE) associated with pediatric asthma medications. METHODS: Following PRISMA guidelines, we systematically searched six bibliographic databases between January 1991 and January 2017. Study eligibility, data extraction and quality assessment were independently completed and verified by two reviewers. We included randomized control trials (RCT), case-control, cohort, or quasi-experimental studies where the primary objective was identifying ADE in children 1 month- 18 years old exposed to commercial asthma medications...

Symptoms, including night-time awakenings, affect the quality of life of people with asthma. Fluticasone furoate/vilanterol (FF/VI) reduces exacerbations, improves lung function, and rescue-free and symptom-free 24-hour periods in patients with asthma. These post-hoc analyses compared daytime and night-time symptoms in patients with asthma who received FF/VI, versus FF, fluticasone propionate (FP) or placebo. Daytime and night-time symptoms were collected via electronic daily diary cards in three Phase III randomized studies of once-daily FF/VI in patients with uncontrolled asthma on inhaled corticosteroids (ICS) ±long-acting beta2-agonists (LABA) (n = 609/1039/586)...

REVIEW

Although early childhood wheeze is common, persistent asthma is less common. However, of those children who do progress to persistent asthma, lung function abnormalities and airway remodelling can already be seen early in life and can increase in magnitude with time. There has been a general expectation that early use of inhaled corticosteroid (ICS) could change the natural history of asthma if started in the young child with wheeze. Despite this expectation, the role of ICS therapy in altering the natural course of disease in children with emerging asthma is not well defined...

REVIEW
Leif D Nelin, J Wells Logan
Bronchopulmonary dysplasia (BPD) is the most usual reason for preterm infants to require chronic mechanical ventilation. Inflammation is a key factor underlying the lung injury leading to the development of BPD, and the rationale for use of corticosteroids in the management of ventilator-dependent preterm infants is based on their anti-inflammatory effects. Because systemic corticosteroids are associated with significant adverse effects in preterm infants, attention has turned to the use of inhaled corticosteroids (ICS) as a potentially safer therapy for BPD...

BACKGROUND: Reduced responsiveness to corticosteroid therapy is a major problem for patients with severe asthma. Although Th9 cells, along with Th2 cells, facilitate antigen-induced airway eosinophilia and bronchial hyperresponsiveness (BHR), the sensitivity of Th9 cell-mediated responses to steroid therapy remains unknown. In this study, we investigated the effect of dexamethasone (Dex) on antigen-induced airway inflammation in Th9 cell-transferred mice. METHODS: Ovalbumin (OVA)-specific Th2 and Th9 cells were polarized from the CD4(+) T cells of DO11...

Mucolytics are potentially useful for the management of chronic obstructive pulmonary disease (COPD), although there is conflicting advice on their use in different guideline documents. Furthermore, there is paucity of data comparing the efficacy of the different mucolytic agents in reducing the odds of COPD exacerbations. We performed pair-wise and network meta-analyses to evaluate the impact of mucoly-tics in COPD. Randomized clinical trials lasting at least 3 months and investigating the effects of mucolytics on COPD exacerbations were identified from published studies and repository databases...

Many trials have been published comparing inhaled corticosteroid (ICS) treatments in asthma. However, mixed results necessitate the summarization of available evidence to aid in decision-making. Areas covered: This systematic review evaluated randomized controlled trials (RCTs) that compared the efficacy and safety of inhaled fluticasone propionate (FP) with ICS including beclomethasone (BDP), budesonide (BUD) and ciclesonide (CIC). PubMed was searched and 54 randomized controlled trials that fit pre-determined criteria were included...

The objective of this study is to evaluate whether a chronic obstructive pulmonary disease (COPD) self-management education program with coaching of a case manager improves patient-related outcomes and leads to practice changes in primary care. COPD patients from six family medicine clinics (FMCs) participated in a 1-year educational program offered by trained case managers who focused on treatment adherence, inhaler techniques, smoking cessation, and the use of an action plan for exacerbations. Health-care utilization, health-related quality of life (HRQL), treatment adherence, inhaler technique, and COPD knowledge were assessed at each visit with validated questionnaires...

Inhaled corticosteroids (ICSs) are the cornerstone of the treatment of asthma, but their role in COPD is limited. Several guidelines recommend their use in patients with severe airflow limitation, frequent exacerbations and asthma-COPD overlap (ACO), while the previous GOLD document recommended ICS for patients with high risk of exacerbations and a high level of symptoms (group D). Following the changes in the GOLD document 2017 update, in which impaired lung function is no longer considered as a determinant of exacerbation risk, a high number of COPD patients can now be labeled as group B (low risk of exacerbations and high level of symptoms) instead of D, and hence, no longer fulfill the indication for ICS...

BACKGROUND: Inhaled corticosteroids (ICSs) are cornerstone therapy for persistent asthma. However, underutilization of ICSs is common and little is known about factors contributing toward this undesirable use. METHODS: A cross-sectional study was conducted through interview and chart review among persistent asthmatic patients attending chest clinic of Tikur Anbessa Specialized Hospital from 1 May to 31 September 2014. A total of 131 eligible patients who attended the clinic during study period were included in the study...

Pulmonary surfactant is a crucial system to stabilize the respiratory air-liquid interface. Furthermore, pulmonary surfactant has been proposed as an effective method for targeting drugs to the lungs. However, few studies have examined in detail the mechanisms of incorporation of drugs into surfactant, the impact of the presence of drugs on pulmonary surfactant performance at the interface under physiologically meaningful conditions, or the ability of pulmonary surfactant to use the air-liquid interface to vehiculise drugs to long distances...

RATIONALE: Many patients with chronic obstructive pulmonary disease (COPD) have an accelerated loss of lung function. It is unclear whether drug treatment can modify this in moderately severe disease. OBJECTIVES: In a pre-specified analysis of the key secondary outcome in the Study to Understand Mortality and MorbidITy (SUMMIT), we investigated whether the inhaled corticosteroid fluticasone furoate 100 μg (FF), the long-acting beta-agonist vilanterol 25 µg (VI) or the combination (FF/VI) modified the rate of decline in FEV1 compared with placebo...

BACKGROUND: Variations in drug response between individuals have prevented us from achieving high drug efficacy in treating many complex diseases, including asthma. Genetics plays an important role in accounting for such inter-individual variations in drug response. However, systematic approaches for addressing how genetic factors and their regulators determine variations in drug response in asthma treatment are lacking. METHODS: We used PANDA (Passing Attributes between Networks for Data Assimilations) to construct the gene regulatory networks associated with good responders and poor responders to inhaled corticosteroids based on a subset of 145 Caucasian asthmatic children who participated in the Childhood Asthma Management Cohort (CAMP)...
