To investigate bone mineral status in children with verified cow milk allergy for more than 4 yr compared with a large reference population of 343 local healthy controls. Whole body bone mineral content (BMC), projected bone area and bone mineral density (BMD) were determined by dual energy x-ray absorptiometry in nine children (8-17 yr old, one girl and eight boys). All children had cow milk allergy for more than 4 yr. All children had asthma and was treated with corticosteroids. BMC and BMD were reduced for age (p < 0.01). Height for age was significantly reduced (p < 0.01), indicating 'short' bones. BMC for bone area was borderline reduced (p = 0.05), indicating reduced bone mineralization. The growth of the children was reduced compared with there parents and siblings (p < 0.01), and the bone age was retarded (mean 1.4 yr, p < 0.01). Calcium consumption calculated from food intake was about 25% of the recommended. All laboratory tests were normal. Short bones were the main reason for reduced BMC and BMD for age in children with cow milk allergy, but a borderline low BMC for bone area indicated reduced bone mineralization of the bones. A supplementation of calcium to children with cow milk allergy is recommended.

The evaluation and management of severe asthma patients require collection of comprehensive information, which is often a challenge in a busy outpatient clinic. The Danish Severe Asthma Register (DSAR) was designed as an electronic patient record form that captures operational clinical data and provides a clinical overview of the severe asthma patient. DSAR is a nationwide register; all patients in Denmark who are treated with biologics for severe asthma are included, and data are as a minimum entered at start of biological treatment, after four and 12 months of treatment, and hereafter annually. Currently, there are data from 621 treatment courses with biologics included in DSAR, with 71% of patients treated with anti-IL-5 drugs and 29% with an anti-IgE drug. Patients enter Patient Reported Outcome Measures electronically on tablets when they arrive in the outpatient clinic and their answers are immediately available to the clinician during the consultation. Nurses and doctors enter clinical data into DSAR during the consultation. DSAR offers immediate access to well-presented longitudinal overview and automatically creates a journal output that can be copy-pasted into the hospital's existing health record form. DSAR is also currently expanding with an app, to be used for monitoring of home-treatment. In addition to serving as an electronic patient record form, DSAR will also provide opportunities to monitor the real-life efficacy of biological treatment for severe asthma in Denmark, and it will be a valuable research platform that will aid in answering important research questions on severe asthma in the future.

Introduction and aimUncontrolled asthma is a global health challenge with substantial impact on quality of life (QoL) and overall healthcare costs. Unrecognised and/or unmanaged comorbidities often contribute to presence of uncontrolled asthma. Abnormalities in breathing pattern are termed dysfunctional breathing and are not only common in asthma but also lead to asthma-like symptoms and reduced QoL, and, in keeping with this, improvement with breathing normalisation. Evidence-based guidelines recommend breathing retraining interventions as an adjuvant treatment in uncontrolled asthma. Physiotherapy-based breathing pattern modification interventions incorporating relaxation have been shown to improve asthma-related QoL in primary care patients with impaired asthma control. Despite anecdotal reports, effectiveness of breathing retraining in patients referred to secondary care with incomplete asthma control has not been formally assessed in a randomised controlled trial (RCT). We aim to investigate the effect of breathing exercises on asthma-related QoL in patients with incomplete asthma control despite specialist care.Methods and analysisThis two-armed assessor-blinded multicentre RCT will investigate the effect of physiotherapist-delivered breathing retraining on asthma QoL questionnaire (MiniAQLQ) in addition to usual specialist care, recruiting from seven outpatient departments and one specialised clinic representing all regions of Denmark during 2017–2019. We will include 190 consenting adults with incomplete asthma control, defined as Asthma Control Questionnaire 6-item score ≥0.8. Participants will randomly be allocated to either breathing exercise programme in addition to usual care (BrEX +UC) or UC alone. BrEX compiles three physiotherapy sessions and encouragement to perform home exercise daily. Both groups continue usual secondary care management. Primary outcome is between-group difference in MiniAQLQ at 6 months. Secondary outcomes include patient-reported outcome measures, spirometry and accelerometer.Ethics and disseminationEthics Committee, Region Zealand (SJ-552) and Danish Data Protection Agency (REG-55–2016) approved the trial. Results will be reported in peer-reviewed scientific journals.Trial registration numberNCT03127059.
