The aim of this study is to evaluate usual care versus biomarker-directed care (using blood eosinophil counts) for the management of asthma patients in primary care setting. The study hypothesizes that BEC is a valuable biomarker that can guide asthma treatment, and result in reduction in asthma exacerbations, better symptom control and improvement in quality of life compared to usual arm in mild to moderate asthma patients in the primary care setting. Researchers would compare using blood eosinophil count guided to usual care to see if biomarker-directed asthma treatment and management
NCT07292805
Rationale: For patients with severe asthma that remain uncontrolled with exacerbations despite biologics or patients who are not eligible for biologics, there is no reimbursed treatment other than pulmonary rehabilitation in the Netherlands. Pulmonary rehabilitation is known to have a limited effect for a limited amount of time. Bronchial thermoplasty or bronchial ablation (BT) is a non-pharmacological treatment for asthma aiming to restore abnormal airway function by using an endobronchial approach. Previous RCT's reported efficacy on exacerbations and asthma related quality of life (AQLQ), but were performed before large availability of biologic treatments. Although a single BT treatment is not without costs, these costs seem to outweigh the costs that can be saved by the long-term (\>5 years) lowering effect of BT on the frequency of exacerbations and hospitalizations and omitting long term use of trials and switches of biologics. Therefore, the investigators hypothesize that BT, in the era of biologics, is superior (in terms of exacerbations and quality of life) over standard care and cost-effective in patients whose asthma remains uncontrolled despite optimal anti-inflammatory treatments including biologics, and the investigators propose to test this hypothesis in a RCT. Objective: To investigate the impact of BT as compared to standard of care in severe asthma patients that remain uncontrolled despite standard treatment including adequate doses of inhaled preventer therapies with or without biologics on: 1. rate of exacerbations 2. asthma related quality of life (AQLQ) 3. 1-year and 5-year cost-effectiveness and cost utility Study design: Investigator-initiated randomized, multicenter, parallel-group interventional RCT of severe asthma patients undergoing either BT (active arm) or standard care (control arm). Study population: Adult, uncontrolled severe asthma patients despite optimal medical therapy including one or more trials of treatment with a biologic or ineligible for biologic treatment AND 2 or more severe asthma exacerbations in the previous year AND FEV1 ≥ 50% predicted. Intervention: BT (active arm) versus standard care (control arm). Main study parameters/endpoints: The primary endpoint of this study is the between group difference in severe exacerbation rate after 12 months of follow-up. The main secondary endpoints are between group differences after 12 months of follow-up and within group differences before and after intervention or standard care. Parameters that will be explored are: AQLQ (minimal clinically important difference \>0.5), ACQ (minimal clinically important difference \>0.5), exacerbation rate (before and after BT) and hospitalizations (rate and % subjects).

While asthma therapy is becoming more individualized based on asthma phenotypes, more research is needed to tailor newer therapies to individuals. Inhaled corticosteroid (ICS) medications are the foundation of care for all individuals with persistent asthma. But ICS use is not without possible long term side effects. This study will compare two currently available approaches to reduce AEX in primary care patients: (1) use of inhaled corticosteroids (ICS) as part of rescue therapy, also known as MART (Maintenance And Reliever Therapy) or PARTICS (Patient Activated Reliever Trigger Inhaled Corticosteriods) therapy - either of these therapies will be called Rescue-Inhaled Corticosteroids or R-ICS pronounced "Ricks," and (2) use of azithromycin (AZ) as a preventive therapy. These treatments will be studied both individually and in combination.

As asthma is chronic condition which interferes with quality of life and exercise tolerance, so it is important to find out cost-effective alternative for the management of asthma due to increased prevalence and rising health care cost as well . Therefore, to provide comprehensive asthma treatment, it is necessary to rule out and address the factor affecting quality of life and exercise tolerance. Asthmatics require stepwise approach which contains assessment treatment planning and review of response. Along with this modification of risk factors, controller therapy is adjusted accordingly. But this is inadequate for asthma management as pharmacological management has some side effects. So, in addition to medical care, Papworth method provides good adjuvant to control asthma symptoms. Asthma subjects require comprehensive approach to deal with these hyperinflation and hyperventilation which are common manifestations of asthma

Acute asthma exacerbations are an important public health problem and a major cause of disease progression and healthcare burden for people with asthma. Frequent acute exacerbations are likely to be a distinct asthma phenotype. Further research is needed to identify risk factors for frequent acute exacerbations, but previous studies have mostly been cross-sectional studies at a single time point or prospective studies based on smaller sample sizes. Moreover, most of the studies on frequent acute exacerbations have been conducted in severe or refractory asthma, whereas a certain proportion of non-severe asthmatics may also experience frequent acute exacerbations, the risk factors of which remain to be further evaluated. The main objectives of this project are to compare the baseline clinical, inflammatory, pathophysiological, comorbidities, environmental pollutants and meteorological exposure characteristics of patients with frequent acute exacerbations and those with non-frequent acute exacerbations irrespective of asthma severity, and to develop a disease prediction model for frequent acute exacerbations; and to develop a cohort of patients with frequent acute exacerbations of asthma, observe their prognosis and response to treatment, and search for prognostic factors associated with them. The successful implementation of this study will help in the early identification of patients with frequent acute exacerbations, clarify the factors associated with poor prognosis in this group of patients, and thus provide an individualized plan for the treatment and prevention of this type of patients, which is of great significance in achieving good asthma control, reducing the burden of disease, decreasing the cost of healthcare, and saving clinical healthcare resources and costs.

The aim was to study whether probiotic intervention has an impact on seasonal occurrence of upper respiratory and gastrointestinal infections in two different conscript groups. In a randomised, double-blinded, placebo controlled study a total of 983 healthy adults were enrolled from two intakes of conscripts. Conscripts were randomised to receive either a probiotic combination of Lactobacillus rhamnosus GG (LGG) and Bifidobacterium animalis ssp. lactis BB12 (BB12) or a control chewing tablet twice daily for 150 days (recruits) or for 90 days (reserve officer candidates). Clinical examinations were carried out and daily symptom diaries were collected. Outcome measures were the number of days with respiratory and gastrointestinal symptoms and symptom incidence, number and duration of infection episodes, number of antibiotic treatments received and number of days out of service because of the infection. Statistically no significant differences were found between the intervention groups either in the risk of symptom incidence or duration. However, probiotic intervention was associated with reduction of specific respiratory infection symptoms in military recruits, but not in reserve officer candidates. Probiotics did not significantly reduce overall respiratory and gastrointestinal infection morbidity.

The aim of this study is to compare the efficacy of a single dose of intramuscular dexamethasone versus 3 days of twice-daily oral prednisolone in the management of mild to moderate asthma exacerbations in children and test whether this single dose of intramuscular dexamethasone 0.6 mg/kg (max. 18 mg) is equal to prednisolone 1 mg/kg/day (max. 40 mg) in the treatment of exacerbations of asthma in children, as measured by the Pediatric Respiratory Assessment Measure (PRAM).
