A comparison of the geometric mean sRaw at 12 hrs post dose in the SFC group to the FP group gave a ratio of 0.76 (0.66 - 0.89, p < 0.001) at week 2 and 0.81 (0.71 - 0.94, p = 0.006) at week 4. Similarly, significant results in favour of SFC for oscillometry measurements of resistance and reactance were observed. FEV1 was also significantly superior at week 2 in the SFC group (mean difference 0.16L, 95% CI; 0.03 - 0.28, p = 0.015), but not at week 4 (mean difference 0.17L, 95% CI -0.01 - 0.34, p = 0.060).

A micellar electrokinetic chromatography method (MEKC) is developed and validated for the analysis of fluticasone propionate (FP) in nasal sprays. The MEKC method is performed on a fused-silica capillary (50 mum i.d.; effective length, 40 cm). The background electrolyte consists of 25 mM borate and 25 mM anionic detergent SDS solution at pH 9. The capillary temperature is maintained at 35 degrees C, and the applied voltage is 20 kV. The injection is performed using the hydrodynamic mode at 50 mbar for 6 s with detection at 238 nm. The method is linear in the range of 2-80 mug/mL (r(2) = 0.9956). The specificity and stability-indicating capability are proven through forced degradation studies inclusive by mass spectrometry, which also shows that there is no interference of the excipients. The limit of detection and limit of quantitation are 0.56 and 2 mug/mL, respectively. Moreover, method validation demonstrates acceptable results for accuracy, precision, and robustness. The proposed method was successfully applied for the quantitative analysis of FP nasal sprays, and the results were compared to a validated reversed-phase liquid chromatographic method, showing non-significant difference (P > 0.05).

A total of 112 children diagnosed with bronchial asthma between September 2012 and October 2013 were assigned to standardized treatment (standard group, n=56) and non-standardized treatment (intermittent group, n=56). Comparisons of clinical symptom scores and main pulmonary function indicators between the two groups were carried out before treatment and at 6 and 12 months after treatment. The growth velocity and changes in body mass index (BMI) were observed in the two groups.

A clinical trial composed of a baseline and an intervention period was conducted at a single tertiary care pediatric ED. Eligible participants were English- or Spanish-speaking parents of children who were 1 to 12 years of age and had a respiratory complaint and history of asthma. Parents used the kiosk to report children's symptoms, current medications, and unmet needs. During a 2-month baseline, no output from the kiosk was shared, and usual care proceeded. During a 3-month intervention that followed a 1-week run-in period, the output was shared with ED clinicians. All parents completed a telephone follow-up interview 1 week after discharge. Primary outcomes were (1) prescription of controller medication to patients who had persistent asthma symptoms and were not on controllers and (2) mean problem scores for 2 specific dimensions of care: information-sharing and partnership.

The aim of this study was to develop a set of reference genes whose expression is stable and suitable for normalization of target gene expression measured in asthma patients during anti-asthmatic treatment. Real-time qPCR was used to determine expression of 7 candidate reference genes (18S rRNA, ACTB, B2M, GAPDH, POLR2A, RPL13A and RPL32) and 7 target genes in leukocytes from asthma patients before and after treatment with inhaled corticosteroids and leukotriene receptor antagonist. Variance of Cq values was analyzed and stability ranking was determined with geNorm. We further investigated how the different normalization strategies affected the consistency of conclusions if the specific investigated target gene is down-regulated or up-regulated after anti-asthmatic therapy. The top-ranking reference genes determined by geNorm, when samples before and after therapy were analyzed (ACTB, B2M and GAPDH) were different from those (POLR2A and B2M) when only samples before treatment were analyzed. Using only a single reference gene for normalization of 7 target gene expression compared to our strategy, there would be as low as 19% of consistency in conclusions. We suggest the use of the geometric mean of ACTB, B2M and GAPDH for normalization of qPCR data of target genes in pharmacogenomics studies in asthma patients before and after anti-asthmatic therapy, however if gene expression is measured only before anti-asthmatic treatment, we recommend the use of the geometric mean of POLR2A and B2M.

Asthma guidelines recommend inhaled corticosteroids (ICS) as the first choice of treatment for children with persistent asthma that is not well controlled when only a reliever inhaler is used to treat symptoms. Steroids work by reducing inflammation in the lungs and are known to control underlying symptoms of asthma. However, parents and physicians remain concerned about the potential negative effect of ICS on growth.

Combining individual drugs in a single inhaler is the most convenient way to deliver triple therapy. A long-acting muscarinic receptor antagonist (LAMA) added to an inhaled corticosteroid (ICS)/long-acting β2-adrenoceptor agonist (LABA) fixed-dose combination (FDC) can improve efficacy of pharmacological treatment of patients with chronic obstructive pulmonary disease (COPD). New inhaled ICS/LABA/LAMA FDCs, including fluticasone furoate/vilanterol/umeclidinium, budesonide/formoterol/glycopyrronium and beclometasone/formoterol/glycopyrronium, are in Phase III of clinical development for COPD. Triple inhaled therapy might be particularly useful in patients with severe to very severe COPD, above all in those with peripheral blood or sputum eosinophilia, asthma-COPD overlap syndrome (ACOS) or frequent exacerbators. Future prospective studies should assess efficacy and safety of triple ICS/LABA/LAMA therapy in selected COPD phenotypes.

Asthma can be divided into at least two distinct molecular phenotypes defined by degree of Th2 inflammation. Th2 cytokines are likely to be a relevant therapeutic target in only a subset of patients with asthma. Furthermore, current models do not adequately explain non-Th2-driven asthma, which represents a significant proportion of patients and responds poorly to current therapies.
FP systemic exposure in terms of AUC(0-24) was lower following inhalation with the Mini Spacer compared with the Aerochamber for both FP 250 μg (Mini Spacer/Aerochamber Ratio 0.76 [90% CI: 0.57-1.01]) and SFC 25/250 μg (Ratio 0.74 [90% CI: 0.56-0.99]). Salmeterol systemic exposure was also lower following SFC 25/250 μg with Mini Spacer compared with Aerochamber (Cmax Ratio 0.90 [90% CI 0.48-1.66]). The incidence of adverse events was low and similar with each treatment.

We included nine RCTs (911 participants), including four different comparisons. None of the studies evaluated our first primary outcome measure, disease-specific HRQL. Fluticasone propionate versus beclomethasone dipropionate We identified two small studies (56 participants with polyps) that evaluated disease severity and looked at the primary adverse effect: epistaxis , but no other outcomes. We cannot report any numerical data but the study authors reported no difference between the two steroids. The evidence was of very low quality. Fluticasone propionate versus mometasone furoate We identified only one study (100 participants with polyps) that evaluated disease severity (nasal symptoms scores), which reported no difference (no numerical data available). The evidence was of very low quality. High-dose versus low-dose steroidsWe included five studies (663 participants with nasal polyps), three using mometasone furoate (400 µg versus 200 µg in adults and older children, 200 µg versus 100 µg in younger children) and two using fluticasone propionate drops (800 µg versus 400 µg). We found low quality evidence relating to disease severity and nasal polyps size, with results from the high-dose and low-dose groups being similar. Although all studies reported more improvement in polyp score in the high-dose group, the significance of this is unclear due to the small size of the improvements.The primary adverse effect, epistaxis , was more common when higher doses were used (risk ratio (RR) 2.06, 95% confidence interval (CI) 1.20 to 3.54, 637 participants, moderate quality evidence). Most of the studies that contributed data to this outcome used a broad definition of epistaxis, which ranged from frank bleeding to bloody nasal discharge to flecks of blood in the mucus. Aqueous nasal spray versus aerosol spray We identified only one poorly reported study (unclear number of participants for comparison of interest, 91 between three treatment arms), in which there were significant baseline differences between the participants in the two groups. We were unable to draw meaningful conclusions from the data.
Inhaled corticosteroids are not as effective as oral corticosteroids in school-aged children with severe acute asthma. It is uncertain how inhaled corticosteroids compare with oral corticosteroids in mild to moderate exacerbations.

A total of 1,263 patients were classified as either GOLD B (n=809) or GOLD D (n=454). At week 26, IND/GLY demonstrated statistically significant improvement in all lung function parameters versus SFC in patients in both the GOLD B and GOLD D subgroups. TDI total score and rescue medication use were significantly improved with IND/GLY versus SFC in the overall population and in the GOLD B (TDI total score only) and GOLD D (rescue medication only) subgroups. IND/GLY also reduced the rate of exacerbations in the pooled population. Overall safety profile was comparable with a higher incidence of pneumonia in the SFC-treated group.
The duration of bronchodilator action of the long-acting beta agonist salmeterol when administered in the evening has not been investigated. In this study we have investigated whether a single evening dose of salmeterol, administered from the combination salmeterol/fluticasone (SFC) Accuhaler significantly attenuates the circadian rhythm in airway tone over 24 h.

Inhaled corticosteroids such as beclometasone are the drugs of choice for long-term treatment of patients with persistent asthma. There is no tangible difference in efficacy among inhaled corticosteroids, but we have the most experience with beclometasone. Ciclesonide (Alvesco, Nycomed then Takeda), another inhaled cortico-steroid, has been tested in three double-blind trials versus budesonide and six trials versus fluticasone but none versus beclometasone. These trials showed the "non-inferiority" of ciclesonide, mainly in terms of a surrogate endpoint: the change in forced expiratory volume in one second (FEV1) after 12 or 24 weeks of treatment (primary endpoint). However, the doses of ciclesonide used in these trials were higher than the standard doses while doses of the comparator corticosteroids were lower than the standard doses, thus favouring ciclesonide. Local adverse effects of inhaled corticosteroids include oral candidiasis, sore throat and hoarseness. A systematic review conducted by a Cochrane group suggests that ciclesonide does not have a better adverse effect profile than other inhaled corticosteroids used at equivalent doses. Corticosteroid inhalation can also lead to systemic absorption. The practical advantage of once-daily dosing with ciclesonide seems minor. In practice, ciclesonide is neither more effective than the inhaled corticosteroids with which it has been compared, nor does it have fewer adverse effects. It is better to continue to use beclometasone, a drug with which there is more experience.
