Budesonide-formoterol reliever therapy versus maintenance budesonide plus terbutaline reliever therapy in adults with mild to moderate asthma (PRACTICAL): a 52-week, open-label, multicentre, superiority, randomised controlled trial.

BACKGROUND: In adults with mild asthma, a combination of an inhaled corticosteroid with a fast-onset long-acting ß-agonist (LABA) used as reliever monotherapy reduces severe exacerbations compared with short-acting ß-agonist (SABA) reliever therapy. We investigated the efficacy of combination budesonide-formoterol reliever therapy compared with maintenance budesonide plus as-needed terbutaline. METHODS: We did a 52-week, open-label, parallel-group, multicentre, superiority, randomised controlled trial at 15 primary care or hospital-based clinical trials units and primary care practices in New Zealand. Participants were adults aged 18-75 years with a self-reported doctor's diagnosis of asthma who were using SABA for symptom relief with or without maintenance low to moderate doses of inhaled corticosteroids in the previous 12 weeks. We randomly assigned participants (1:1) to either reliever therapy with budesonide 200 µg-formoterol 6 µg Turbuhaler (one inhalation as needed for relief of symptoms) or maintenance budesonide 200 µg Turbuhaler (one inhalation twice daily) plus terbutaline 250 µg Turbuhaler (two inhalations as needed). Participants and investigators were not masked to group assignment; the statistician was masked for analysis of the primary outcome. Six study visits were scheduled: randomisation, and weeks 4, 16, 28, 40, and 52. The primary outcome was the number of severe exacerbations per patient per year analysed by intention to treat (severe exacerbations defined as use of systemic corticosteroids for at least 3 days because of asthma, or admission to hospital or an emergency department visit because of asthma requiring systemic corticosteroids). Safety analyses included all participants who had received at least one dose of study treatment. This trial is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12616000377437. FINDINGS: Between May 4, 2016, and Dec 22, 2017, we assigned 890 participants to treatment and included 885 eligible participants in the analysis: 437 assigned to budesonide-formoterol as needed and 448 to budesonide maintenance plus terbutaline as needed. Severe exacerbations per patient per year were lower with as-needed budesonide-formoterol than with maintenance budesonide plus terbutaline as needed (absolute rate per patient per year 0·119 vs 0·172; relative rate 0·69, 95% CI 0·48-1·00; p=0·049). Nasopharyngitis was the most common adverse event in both groups, occurring in 154 (35%) of 440 patients receiving as-needed budesonide-formoterol and 144 (32%) of 448 receiving maintenance budesonide plus terbutaline as needed. INTERPRETATION: In adults with mild to moderate asthma, budesonide-formoterol used as needed for symptom relief was more effective at preventing severe exacerbations than maintenance low-dose budesonide plus as-needed terbutaline. The findings support the 2019 Global Initiative for Asthma recommendation that inhaled corticosteroid-formoterol reliever therapy is an alternative regimen to daily low-dose inhaled corticosteroid for patients with mild asthma.

Patient preferences for symptom-driven or regular preventer treatment in mild to moderate asthma: findings from the PRACTICAL study, a randomised clinical trial.

Symptom-driven low-dose inhaled corticosteroid-formoterol is safe and effective in mild asthma and has been recommended as one of the preferred treatment regimens at steps 1 and 2 in the 2019 update of the Global Initiative for Asthma. However, there are no data on patient preferences for this regimen.A subgroup of participants in the PRACTICAL study (ACTRN12616000377437), a randomised controlled trial comparing symptom-driven budesonide-formoterol with maintenance budesonide plus as-needed terbutaline completed a survey on treatment preferences, satisfaction, beliefs and experience at their final study visit.306 (75%) out of 407 eligible participants completed the survey. Regimen preference was strongly associated with randomised treatment, as were preferences for and beliefs about preventer inhaler use. Combination preventer and reliever as-needed therapy was preferred by 135 (90%, 95% CI 85.2-94.8%) out of 150 who were randomised to as-needed budesonide-formoterol, and by 63 (40%, 95% CI 32.7-48.1%) out of 156 who were randomised to maintenance budesonide. By contrast, twice-daily preventer inhaler with a reliever inhaler as required was preferred by 15 (10%) out of 150 of those randomised to as-needed budesonide-formoterol and 93 (60%) out of 156 of those randomised to maintenance budesonide. Satisfaction with all study inhalers was high. Of patients randomised to as-needed budesonide-formoterol 92% (n=138) were confident using it as a reliever at the end of the study.Although most participants preferred the regimen to which they had been randomised, this association was much stronger for those randomised to budesonide-formoterol as needed, indicating that most patients preferred as-needed corticosteroid-formoterol therapy if they had experienced it.

The Children's Anti-inflammatory Reliever (CARE) study: a protocol for a randomised controlled trial of budesonide-formoterol as sole reliever therapy in children with mild asthma.

BACKGROUND: Asthma is the most common chronic disease in children, many of whom are managed solely with a short-acting ß2-agonist (SABA). In adults, the evidence that budesonide-formoterol as sole reliever therapy markedly reduces the risk of severe exacerbations compared with SABA alone has contributed to the Global Initiative for Asthma recommending against SABA monotherapy in this population. The current lack of evidence in children means it is unknown whether these findings are also relevant to this demographic. High-quality randomised controlled trials (RCTs) are needed. OBJECTIVE: The aim of this study is to determine the efficacy and safety of as-needed budesonide-formoterol therapy compared with as-needed salbutamol in children aged 5 to 15 years with mild asthma, who only use a SABA. METHODS: A 52-week, open-label, parallel group, phase III RCT will recruit 380 children aged 5 to 15 years with mild asthma. Participants will be randomised 1:1 to either budesonide-formoterol (Symbicort Rapihaler®) 50/3 µg, two actuations as needed, or salbutamol (Ventolin®) 100  µg, two actuations as needed. The primary outcome is asthma attacks as rate per participant per year. Secondary outcomes assess asthma control, lung function, exhaled nitric oxide and treatment step change. A cost-effectiveness analysis is also planned. CONCLUSION: This is the first RCT to assess the safety and efficacy of as-needed budesonide-formoterol in children with mild asthma. The results will provide a much-needed evidence base for the treatment of mild asthma in children.

Being well and wellbeing: better understanding of patient priorities in primary care.

INTRODUCTION Achieving desired health outcomes in primary care can be challenging because of dissonance between the theory and reality of medicine, inadequate understanding of patient perspectives and priorities regarding wellness, wellbeing and goals of treatment, and under-emphasis of the concept of whole-person care in the doctor-patient relationship. ASSESSMENT OF PROBLEMS Anticipated dissonance in the doctor-patient relationship was explored using a self-designed audit, which also functioned as an educational and engagement tool. RESULTS OF ASSESSMENT Most respondents appreciated the opportunity, with a small number commenting on the challenging nature of the question. STRATEGIES FOR QUALITY IMPROVEMENT Entering audit findings into the patient's clinical record in a format accessible to all clinical staff enables increased opportunity for patients to be valued and engaged with. Goal setting and therapeutic choices can be made in the light of a better understanding of what matters most to the patient. LESSONS AND MESSAGES This project provided valuable and, at times surprising, information to clinical consultations that had not previously been obtained from or offered by patients. Such information requires an intentional, engaged and collaborative interaction with the patient, and enhances patient-centric consultations with a focus on whole-person care and wellness in the journey to therapeutic goals and health outcomes.

Successful Treatment of Actinic Keratosis with Kanuka Honey.

Actinic keratoses form as rough, scaly plaques on sun-exposed areas; they can be an important step in premalignant progression to squamous cell cancer of the skin. Currently, pharmacological treatments consist of topical immunomodulatory agents with poor side effect profiles. Use of honey has been common in both ancient and modern medicine, where it is now a key therapy in the management of wound healing. In vitro studies show the New Zealand native Kanuka honey to have immunomodulatory and antimitotic effects, with recent evidence suggesting efficacy of topical application in a variety of dermatological contexts, including rosacea and psoriasis. Here, we present a case report of a 66-year-old gentleman with an actinic keratosis on his hand, which had been present for years. Regular application of Kanuka honey over three months resulted in remission immediately following the treatment period with no signs of recurrence at nine months.

Description of the protocol for the PRACTICAL study: a randomised controlled trial of the efficacy and safety of ICS/LABA reliever therapy in asthma.

INTRODUCTION: In adult asthma, combination inhaled corticosteroid (ICS)/fast-onset long-acting beta agonist (LABA) used solely as reliever therapy may represent an effective and safe alternative to ICS maintenance and short-acting beta agonist (SABA) reliever therapy. OBJECTIVE: To compare the efficacy and safety of ICS/fast-onset LABA reliever therapy with ICS maintenance and SABA reliever therapy in adults with asthma. METHODS AND ANALYSIS: A 52-week, open-label, parallel group, multicentre, phase III randomised controlled trial with 1:1 randomisation to either budesonide/formoterol Turbuhaler 200/6 µg, one actuation as required for symptom relief, or budesonide Turbuhaler 200 µg, one actuation twice daily and terbutaline Turbuhaler 250 µg, two actuations as required for symptom relief. 890 adults aged 18-75 years with asthma for whom maintenance ICS and SABA reliever therapy is indicated by current guidelines will be recruited in New Zealand. The primary outcome variable is the rate of severe exacerbations per patient per year. This study will investigate a novel treatment regimen that might lead to a paradigm shift in asthma management for adults for whom guidelines currently recommend maintenance ICS and SABA reliever therapy. ETHICS AND DISSEMINATION: Ethical approval has been granted (15/NTB/178). Study findings will be published according to Iinternational Committee of Medical Journal Editors' recommendations.

Randomised controlled trial of topical kanuka honey for the treatment of acne.

OBJECTIVE: To investigate the efficacy of Honevo, a topical 90% medical-grade kanuka honey, and 10% glycerine (honey product) as a treatment for facial acne. DESIGN: Randomised controlled trial with single blind assessment of primary outcome variable. SETTING: Outpatient primary care from 3 New Zealand localities. PARTICIPANTS: Of 136 participants aged between 16 and 40 years with a diagnosis of acne and baseline Investigator's Global Assessment (IGA) for acne score of ≥ 2.68, participants were randomised to each treatment arm. INTERVENTIONS: All participants applied Protex, a triclocarban-based antibacterial soap twice daily for 12 weeks. Participants randomised to the honey product treatment arm applied this directly after washing off the antibacterial soap, twice daily for 12 weeks. OUTCOME MEASURES: The primary outcome was ≥ 2 point decrease in IGA score from baseline at 12 weeks. Secondary outcomes included mean lesion counts and changes in subject-rated acne improvement and severity at weeks 4 and 12, and withdrawals for worsening acne. RESULTS: 4/53 (7.6%) participants in the honey product group and 1/53 (1.9%) of participants in the control group had a ≥ 2 improvement in IGA score at week 12, compared with baseline, OR (95% CI) for improvement 4.2 (0.5 to 39.3), p=0.17. There were 15 and 14 participants who withdrew from the honey product group and control group, respectively. CONCLUSIONS: This randomised controlled trial did not find evidence that addition of medical-grade kanuka honey in combination with 10% glycerine to standard antibacterial soap treatment is more effective than the use of antibacterial soap alone in the treatment of acne.

Randomised controlled trial of topical kanuka honey for the treatment of rosacea.

OBJECTIVE: To investigate the efficacy of topical 90% medical-grade kanuka honey and 10% glycerine (Honevo) as a treatment for rosacea. DESIGN: Randomised controlled trial with blinded assessment of primary outcome variable. SETTING: Outpatient primary healthcare population from 5 New Zealand sites. PARTICIPANTS: 138 adults aged ≥ 16, with a diagnosis of rosacea, and a baseline blinded Investigator Global Assessment of Rosacea Severity Score (IGA-RSS) of ≥ 2. 69 participants were randomised to each treatment arm. 1 participant was excluded from the Honevo group, and 7 and 15 participants withdrew from the Honevo and control groups, respectively. INTERVENTIONS: Participants were randomly allocated 1:1 to Honevo or control cream (Cetomacrogol), applied twice daily for 8 weeks. MAIN OUTCOME MEASURES: The primary outcome measure was the proportion of participants who had a ≥ 2 improvement in the 7-point IGA-RSS at week 8 compared to baseline. Secondary outcomes included change in IGA-RSS and subject-rated visual analogue score of change in severity (VAS-CS) on a 100 mm scale (0 mm 'much worse', 100 mm 'much improved') at weeks 2 and 8. RESULTS: 24/68 (34.3%) in the Honevo group and 12/69 (17.4%) in the control group had a ≥ 2 improvement in IGA-RSS at week 8 compared to baseline (relative risk 2.03; 95% CI 1.11 to 3.72, p=0.020). The change in IGA-RSS for Honevo compared to control at week 2 minus baseline was -1 (Hodges-Lehman estimate, 95% CI -1 to 0, p=0.03), and at week 8 minus baseline was -1 (Hodges-Lehman estimate, 95% CI -1 to 0, p=0.005). The VAS-CS at week 2 was 9.1 (95% CI 3.5 to 14.7), p=0.002, and at week 8 was 12.3 (95% CI 5.7 to 18.9)¸ p<0.001 for Honevo compared to control. CONCLUSIONS: Honevo is an effective treatment for rosacea. TRIAL REGISTRATION NUMBER: This trial was registered in the Australian and New Zealand Clinical Trials Registry ACTRN12614000004662.
