Filter by:The objective of this study was to determine the effects of Swedish massage prior circuit breathing training on asthma control and respiratory function in patients with asthma.
Rationale: Despite the availability of effective treatment to reach symptom control, nearly half of the asthma patients remain inadequately controlled. There is a need for timely and appropriate treatment of patients with uncontrolled asthma. Improving asthma control could be achieved by a better identification of causes followed by remediating modifiable factors in primary care or referral to secondary care. However, major gaps in evidence-based asthma practice exist in primary care. So far, there is a lack of knowledge on the prevalence of inadequate asthma and associated characteristics. Objective: The primary objective is to determine the proportion of primary care patients with inadequate asthma control, as assessed during a regular control consultation with the general practice nurse. Study design: This is a non-interventional prospective observational study, taking place in a real-world primary care setting. The AsthmaOptimiser tool will be used during regular asthma consultations in primary care, which the healthcare provider will fill in together with the patient. The AsthmaOptimiser tool creates an overview of factors and characteristics that may be associated with uncontrolled asthma, and subsequently provides a guideline-based management suggestion. Additionally, we will perform qualitative interviews to collect experiences and perspectives of healthcare providers on their use of the AsthmaOptimiser tool, including, but not limited to, ease of use, points of improvement, and on their implementation of the management suggestions. Study population: Patients diagnosed with asthma, who attend a pre-planned primary care asthma review, are eligible to participate. A limited number of in- and exclusion criteria will be adopted, to make sure the research population closely resembles the real world. Main study parameters/endpoints: The primary endpoint is the proportion of patients with inadequate asthma control. Inadequate asthma control will be defined as an exacerbation in the past 4 weeks and/or an ACQ6 (i.e., Asthma Control Questionnaire) score >0.75.
Objective: To determine the extent to which high-dose (30mg) oral montelukast, added to standard treatment in children with moderate and severe acute exacerbations improves outcomes. Central Hypothesis: High-dose oral montelukast, added to standard treatment in children aged 5 to 17 years with moderate and severe acute asthma exacerbations, rapidly improves lung function, clinical severity, hospitalization rate and 72-hour symptom burden. Secondary Hypotheses: 1. There are greater effects of high-dose oral montelukast on lung function and on the secondary outcomes in the presence of respiratory viral detection or leukotriene-mediated inflammation; and 2. There is an interaction between viral detection and urinary leukotriene 4 level with treatment-response. Design: A two-arm, parallel randomized controlled trial of high-dose oral montelukast versus identical placebo, as add-on to standard treatment, in children aged 5 to 17 years with moderate and severe acute asthma exacerbations. Intervention: High-dose oral montelukast added to standard treatment in comparison with standard treatment as the 2nd treatment-allocation arm. Primary and Important Secondary Endpoints: For the Primary Aim, the primary outcome measure to be compared between arms will be change of %-predicted airway resistance by impulse oscillometry (IOS) at 5Hz (%R5) at 2 hours after treatment initiation. Secondary outcomes will include improvement of %-predicted FEV1 (%FEV1), clinical severity measured using the validated Acute Asthma Intensity Research Score (AAIRS), hospitalization rate, and 72 hour symptom burden using the Pediatric Asthma Caregiver Diary (PACD). For the Secondary Aim, the investigators will determine (1) The effects of high-dose oral montelukast on lung function and on our secondary outcomes in the presence of nasal viruses and of greater leukotriene-mediated inflammation; and (2) The degree of interaction between viral detection and urinary leukotriene E4 (LTE4) level with treatment-response. Laboratory evaluations: The primary outcome (change of %R5) and select secondary outcomes (%FEV1, AAIRS, LTE4) will be measured before and again at 2 hours after treatment initiation. The other secondary outcomes will be measured at the time of hospitalization decision-making by the clinical team (hospitalization rate) or at 72-hours after treatment initiation (PACD).
