Among more than 11,000 patients with moderate-to-severe asthma, fluticasone–salmeterol was noninferior to fluticasone alone with respect to severe asthma events. The safe and appropriate use of short-acting beta-agonists (SABAs) and long-acting beta-agonists (LABAs) for the treatment of asthma has been widely debated. 1 In early reports, SABAs were associated with an increased risk of asthma-related death. 2 , 3 In the 1990s, analyses suggested that high use of SABAs (>1.5 to 2 canisters per month) might increase the risk of death or near-fatal asthma. 4 – 6 In one of these studies, the authors postulated that high use of SABAs was either a marker of poorly controlled asthma or a “toxic effect of the medications or their vehicles.” 6 Two large clinical trials, the Serevent Nationwide . . .

Chronic obstructive pulmonary disease (COPD) often coexists with cardiovascular disease. Treatments for airflow limitation might improve survival and both respiratory and cardiovascular outcomes. The aim of this study was to assess whether inhaled treatment with a combined treatment of the corticosteroid, fluticasone furoate, and the long-acting β agonist, vilanterol could improve survival compared with placebo in patients with moderate COPD and heightened cardiovascular risk. In this double-blind randomised controlled trial (SUMMIT) done in 1368 centres in 43 countries, eligible patients were aged 40–80 years and had a post-bronchodilator forced expiratory volume in 1 s (FEV1) between 50% and 70% of the predicted value, a ratio of post-bronchodilator FEV1 to forced vital capacity (FVC) of 0·70 or less, a smoking history of at least 10 pack-years, and a score of 2 or greater on the modified Medical Research Council dyspnoea scale. Patients had to have a history, or be at increased risk, of cardiovascular disease. Enrolled patients were randomly assigned (1:1:1:1) through a centralised randomisation service in permuted blocks to receive once daily inhaled placebo, fluticasone furoate (100 μg), vilanterol (25 μg), or the combination of fluticasone furoate (100 μg) and vilanterol (25 μg). The primary outcome was all-cause mortality, and secondary outcomes were on-treatment rate of decline in forced expiratory volume in 1 s (FEV1) and a composite of cardiovascular events. Safety analyses were performed on the safety population (all patients who took at least one dose of study drug) and efficacy analyses were performed on the intention-to-treat population (safety population minus sites excluded with Good Clinical Practice violations). This study is registered with ClinicalTrials.gov, number NCT01313676. Between Jan 24, 2011, and March 12, 2014, 23 835 patients were screened, of whom 16 590 were randomised. 16 485 patients were included in the intention-to-treat efficacy population; 4111 in the placebo group, 4135 in the fluticasone furoate group, 4118 in the vilanterol group, and 4121 in the combination group. Compared with placebo, all-cause mortality was unaffected by combination therapy (hazard ratio [HR] 0·88 [95% CI 0·74–1·04]; 12% relative reduction; p=0·137) or the components (fluticasone furoate, HR 0·91 [0·77–1·08]; p=0·284; vilanterol, 0·96 [0·81–1·14]; p=0·655), and therefore secondary outcomes should be interpreted with caution. Rate of decline in FEV1 was reduced by combination therapy (38 mL per year [SE 2·4] vs 46 mL per year [2·5] for placebo, difference 8 mL per year [95% CI 1–15]) with similar findings for fluticasone furoate (difference 8 mL per year [95% CI 1–14]), but not vilanterol (difference −2 mL per year [95% CI −8 to 5]). Combination therapy had no effect on composite cardiovascular events (HR 0·93 [95% CI 0·75–1·14]) with similar findings for fluticasone furoate (0·90 [0·72–1·11]) and vilanterol (0·99 [0·80–1·22]). All treatments reduced the rate of moderate and severe exacerbation. No reported excess risks of pneumonia (5% in the placebo group, 6% in the combination group, 5% in the fluticasone furoate group, and 4% in the vilanterol group) or adverse cardiac events (17% in the placebo group, 18% in the combination group, and 17% in the fluticasone furoate group, and 17% in the vilanterol group) were noted in the treatment groups. In patients with moderate COPD and heightened cardiovascular risk, treatment with fluticasone furoate and vilanterol did not affect mortality or cardiovascular outcomes, reduced exacerbations, and was well tolerated. Fluticasone furoate, alone or in combination with vilanterol, seemed to reduce FEV1 decline. GlaxoSmithKline.

The airway microbiome has an important role in asthma pathophysiology. However, little is known on the relationships between the airway microbiome of asthmatic children, loss of asthma control, and severe exacerbations. Here we report that the microbiota’s dynamic patterns and compositions are related to asthma exacerbations. We collected nasal blow samples (n = 319) longitudinally during a clinical trial at 2 time-points within one year: randomization when asthma is under control, and at time of early loss of asthma control (yellow zone (YZ)). We report that participants whose microbiota was dominated by the commensal Corynebacterium   +   Dolosigranulum cluster at RD experience the lowest rates of YZs (p = 0.005) and have longer time to develop at least 2 episodes of YZ (p = 0.03). The airway microbiota have changed from randomization to YZ. A switch from the Corynebacterium   +   Dolosigranulum cluster at randomization to the Moraxella- cluster at YZ poses the highest risk of severe asthma exacerbation (p = 0.04). Corynebacterium’s relative abundance at YZ is inversely associated with severe exacerbation (p = 0.002). How the airway microbiome influences asthma pathophysiology remains unclear. Here, the authors analyse nasal samples of cohort of school-age children with persistent asthma and find that the microbiota’s patterns and composition at time of early loss of asthma control associate with severe asthma exacerbations.

Patients with obstructive sleep apnea (OSA) often struggle with CPAP therapy adherence. The intranasal corticosteroids (INS) alone have not significantly improved CPAP adherence but the combination drugs that faster relieved symptoms were not well studied. This study aimed to assess the combined effectiveness of INS (fluticasone propionate) and intranasal antihistamines (azelastine hydrochloride) in enhancing CPAP adherence and mitigating CPAP-induced rhinitis symptoms in OSA patients. A double-blind, randomized controlled trial with stratified random sampling was conducted at Thammasat University Hospital from March 2022 to March 2023. Participants included OSA patients undergoing CPAP treatment. The patients completed questionnaires and interviews at the baseline, the second week, and one month after starting CPAP therapy, with CPAP usage electronic data collected. Among 116 enrolled patients, most had severe OSA (78.9%), with a majority being male (56.9%). The intervention group did not significantly differ from the placebo group in terms of CPAP usage, nasal symptoms, quality of life, or side effects. Subgroup analysis showed improved CPAP adherence in the treatment group when using pressure below 15 cm H 2 O (7.8% increase in CPAP usage days, P  = 0.04). This study marks the first evaluation of combination drugs for enhancing CPAP therapy adherence in OSA patients. Although these drugs did not significantly enhance overall CPAP adherence, there was a trend toward increasing CPAP adherence in patients using lower pressure levels. Thus, combining fluticasone and azelastine may benefit certain OSA patients. Further research is essential to comprehend and validate these benefits fully.

ObjectiveTo assess the effectiveness of a potent topical corticosteroid (TCS) as an initial treatment in primary care for children with moderate flare-ups of atopic dermatitis (AD), compared to starting on a mild TCS.DesignAn observational prospective cohort study with an embedded pragmatic multicentre open-label randomised controlled trial.SettingA total of 53 general practices in the southwest of the Netherlands took part in the study.Participants209 children aged 3 months to 17 years diagnosed with AD (International Classification of Primary Care codes S87 or S88) who visited their general practitioner (GP) for AD or received repeat prescriptions for AD in the previous 12 months were included in the cohort study through the general practices. Finally, 32 patients (15%) were randomised and assigned to the trial (13 girls; 19 boys; median age 4.0 years).InterventionsIf cohort participants experienced a moderate flare-up (ie, need to intensify topical treatment from the child’s and/or parents’ point of view of AD and a three-item severity score from three to<6 scored by their GP) during cohort follow-up, they were randomised to either the intervention group, a strong TCS (class III, fluticasone propionate 0.05%), or the control group, a mild TCS (class I, hydrocortisone acetate 1%).Primary and secondary outcome measuresWe measured outcomes at baseline and at 1, 4 and 24 weeks. The primary outcome was AD-related symptoms (Patient-Oriented Eczema Measure (POEM) score) measured over 24 weeks of follow-up. Secondary outcomes included the Eczema Area and Severity Index, the Investigators Global Assessment, quality of life (QoL), Patient Global Assessment, Numeric Itch Intensity Score and TCS use.ResultsThe primary outcome showed a significant difference in the POEM scores over 24 weeks of follow-up between the intervention group (n=17) and the control group (n=15) (3.3 vs 9.4, p=0.023). The potent TCS also significantly improved the POEM at 1 week (5.5 vs 12.0, p=0.042) and 4 weeks (4.3 vs 12.7, p=0.030). Improvement in the QoL was significant at 4 weeks (1.0 vs 4.5, p=0.014) and 24 weeks (0.0 vs 2.0, p=<0.000).ConclusionDespite the small sample size, the data suggests a clinical benefit from starting with a potent TCS rather than a mild TCS when a flare-up of AD is moderate.Trial registrationThe Netherlands National Trial Register: NTR6679.

It was to investigate the clinical efficacy of the combination therapy of fluticasone propionate inhalation aerosol and vitamin D (VD) in pediatric bronchial asthma (BA) and analyze the correlation between serum 25-(OH)-D3 levels and immune function, as well as calcium-phosphorus metabolism. A total of 110 patients with BA were recruited. Regarding treatment plan, patients were randomly rolled into a single-drug treatment group (SDT, treated with fluticasone propionate inhalation aerosol alone) and a dual-drug treatment group (TDT, treated with the combination of fluticasone propionate inhalation aerosol and VD). The changes in serum 25-(OH)-D3 levels, immunoglobulins, T lymphocyte subsets, and inflammatory cytokine levels in children with BA under different treatment modalities were compared. Clinical symptom disappearance, asthma control, and quality of life (QoL) were assessed, and the total effective rate and adverse reactions (ARs) were compared. A control group consisting of 60 healthy children who underwent concurrent physical examinations was included. The differences in serum 25-(OH)-D3 levels, immunoglobulins, and T lymphocyte subset levels between children with BA and healthy controls were compared, and their correlations were analyzed. The TDT group showed a drastic reduction in the disappearance time of lung wheezing and dyspnea relative to the SDT group. Furthermore, the TDT group exhibited notable improvements in lung function parameters, including forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC, and peak expiratory flow (PEF). Blood gas analysis revealed a great decrease in PaCO2 and an increase in PaO2. The Childhood Asthma Control Test (C-ACT) scores for asthma control and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) scores for QoL showed marked increases in the TDT group. Moreover, the TDT group demonstrated notable increases in serum 25-(OH)-D3 levels, immunoglobulins (IgA, IgG, and IgM), T lymphocyte subsets (CD4+ and CD8+), as well as blood calcium and phosphorus levels. Additionally, the TDT group exhibited a prominent increase in the anti-inflammatory cytokine interleukin (IL)-10 level and a drastic decrease in the pro-inflammatory cytokines IL-6 and tumor necrosis factor alpha (TNF-α) levels (all P<0.05). The total effective rates of treatment in the SDT group and TDT group were 83.64 % and 96.36 %, respectively, with AR rates of 16.36 % and 7.27 %. The TDT group exhibited a superior total effective rate and an inferior incidence of ARs to the SDT group (both P<0.05). Additionally, in contrast to the control group, the BA group showed notable decreases in serum 25-(OH)-D3 levels, immunoglobulins (IgA, IgG, and IgM), T lymphocyte subsets (CD4+, CD8+, and CD4+/CD8+), as well as blood calcium and phosphorus levels (all P<0.05). Prior to treatment, there was a positive correlation between serum 25-(OH)-D3 levels and immunoglobulins (IgA, IgG, and IgM), T lymphocyte subsets (CD4+ and CD8+), as well as blood calcium and phosphorus levels in children with BA (P<0.05). In patients with BA, combined treatment with inhaled fluticasone propionate aerosol and VD may have a regulatory effect on serum 25-hydroxyVD levels, immune function, and calcium-phosphate metabolism. The correlation between serum 25-(OH)-D3 levels and immune function, as well as calcium-phosphate metabolism, suggested that VD may play a crucial role in the immune regulation and calcium-phosphate metabolism of BA.

Background/Aims: Atopic dermatitis (AD) is a common disease in infancy, for which topical steroids are the first-line therapy but have side effects. Innovative approaches are needed to reduce the burden of AD and corticosteroid usage in infants. Methods: The once-daily consumption of heat-treated probiotic Lactobacillus paracasei GM-080 or placebo for 16 weeks as supplementary approach to topical treatment with fluticasone propionate cream was compared in AD infants aged 4–30 months. Outcomes were SCORAD and its subscores, TEWL, Infants’ Dermatitis Quality of Life Index (IDQOL), corticoid “sparing effect,” CCL17/TARC, and IgE status. Results: SCORAD, objective SCORAD, itching, and IDQOL decreased significantly (p < 0.001) over the treatment period in both treatment groups. Slight decreases (ns) were noted in TEWL in lesional and unaffected skin and CCL17 levels. There were no differences between the treatment groups. Total IgE increased over the treatment period in both groups, with significantly higher increase in the heat-treated probiotic group (p = 0.038). There was no evidence of a corticoid “sparing effect” by the probiotic. Conclusions: In this design, the probiotic L. paracasei was not beneficial as a complementary approach to topical corticosteroids in infants with AD. However, slight beneficial effects may have been masked by the moderate potency corticoid.

Background Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulopathy worldwide, and lacks the effective treatment. The study was aimed to investigate the clinical efficacy of fluticasone propionate aerosol combined with angiotensin converting enzyme inhibitor / angiotensin receptor blocker (ACEI/ARB) in the treatment of IgAN. Methods 142 patients with biopsy-proven IgAN at Shenzhen People?s hospital from June 2018 to June 2020 were enrolled. The patients were randomly divided into the supportive care plus fluticasone group and the supportive care group. The patients of the supportive care plus fluticasone group were treated with fluticasone propionate aerosol (250 ?g Bid) combined with ACEI/ARB, while the supportive care group was merely treated with ACEI/ARB. The patients were followed up at 3, 6 and 9 months after enrollment. Primary outcomes include changes in proteinuria and estimated glomerular filtration rate (eGFR). Results The level of proteinuria in the supportive care plus fluticasone group was significantly lower compared with the supportive care group at 0, 3, 6 and 9 months. Meanwhile, during the follow-up period, no serious adverse events were recorded during the study in either group. However, fluticasone treatment did not alleviate the decline in eGFR. Conclusion Fluticasone propionate aerosol combined with ACEI/ARB can reduce the level of proteinuria in thetreatment of IgAN, and has no significant effects on renal function.

Chronic obstructive pulmonary disease exacerbations accelerate lung function decline, reduce quality of life, and increase mortality. A subset of patients (n = 457) from the FLAME (Effect of Indacaterol Glycopyrronium vs. Fluticasone Salmeterol on COPD Exacerbations) study used the Exacerbations of COPD Tool (EXACT) to capture symptom-defined exacerbations. To evaluate the effect of indacaterol/glycopyrronium versus salmeterol/fluticasone on symptom-defined exacerbations measured using EXACT, and to assess differences between these events and exacerbations requiring healthcare resource use (HCRU). All patients in FLAME used an electronic diary to record and detect symptom deteriorations; HCRU-related exacerbations were confirmed by investigators. In patients using the EXACT questionnaire, the onset, recovery, and magnitude of symptom-defined exacerbations were identified by changes in total scores relative to baseline. We analyzed the annualized rate and time to first symptom-defined (EXACT) exacerbation and assessed differences between symptom-defined and HCRU events in terms of number, severity, and concordance. A nonsignificant 17% reduction in the annualized rate of symptom-defined (EXACT) exacerbations (rate ratio, 0.83; 95% confidence interval [CI], 0.60-1.14; P = 0.242) and a numerically longer time to first symptom-defined exacerbation were observed with indacaterol/glycopyrronium versus salmeterol/fluticasone (hazard ratio, 0.76; 95% CI, 0.56-1.03; P = 0.075). These results were consistent with data from the overall FLAME population. Of the symptom-defined (EXACT) events, 23.5% corresponded to HCRU events, and 22.2% of HRCU events were captured by EXACT (κ index, 0.24; 95% CI, 0.15-0.33). Regardless of the exacerbation definition used, our findings support the use of long-acting β agonists/long-acting muscarinic receptor antagonists as the preferred treatment option for patients at risk of future exacerbations.

Allergic rhinitis (AR) is the inflammation of the membranes lining the nose due to allergen exposure and is characterized by sneezing, nasal congestion, itching of the nose, or postnasal discharge. The prevalence varies worldwide, perhaps due to the geographic and aeroallergen differences, with 10% to 30% of the world's population experiencing AR. In this study, Anu Taila Nasya, Naradiya Laxmivilas Rasa, and Shirishadi Kwath will be compared to a fluticasone nasal spray. The primary aim is to assess the efficacy of Ayurvedic management for AR (or vataja pratishyaya) by comparing it to a conventional control group. The secondary aims are to determine the mean change in the nasal endoscopy index and the mean change in the laboratory tests. This ongoing study is an open-label randomized controlled interventional trial, with a sample size of 90 both in the trial and standard control group (including dropouts, 20%), and will be carried out for 24 months. Participants in the trial group will receive Ayurvedic treatment, that is, Anu Taila Nasya (6 drops in each nostril for 7 days for 3 consecutive weeks), Naradiya Laxmivilas Rasa (250 mg twice per day), and Shirishadi Kwath (40 ml twice per day for 45 days). The participants in the control group will receive a fluticasone propionate nasal spray (2 sprays once per day for 45 days). The primary outcome will include the mean change in the Control of Allergic Rhinitis and Asthma Test score, and the secondary outcomes will include the mean change in the nasal endoscopy index (assessment of nasal membrane color, pale or hyperemia; rhinorrhea, watery or yellow; and inferior turbinate swelling, hypertrophy) and the mean change in the laboratory tests. As of May 2024, 72 patients have been enrolled in both groups. Data analysis should be completed by February 2025. The study will be reported following standard guidelines for reporting randomized controlled trials. Clinical results will be disseminated through conferences and peer-reviewed publication in a relevant journal. The Ayurvedic approach could be an evidence-based therapeutic tactic for the management of AR. Clinical Trials Registry India CTRI/2023/06/053395; https://tinyurl.com/564d2zz8. DERR1-10.2196/56063.
