COPD - do the right thing.

A gap exists between guidelines and real-world clinical practice for the management and treatment of chronic obstructive pulmonary disease (COPD). Although this has narrowed in the last decade, there is room for improvement in detection rates, treatment choices and disease monitoring. In practical terms, primary care practitioners need to become aware of the huge impact of COPD on patients, have non-judgemental views of smoking and of COPD as a chronic disease, use a holistic consultation approach and actively motivate patients to adhere to treatment.This article is based on discussions at a virtual meeting of leading Nordic experts in COPD (the authors) who were developing an educational programme for COPD primary care in the Nordic region. The article aims to describe the diagnosis and lifelong management cycle of COPD, with a strong focus on providing a hands-on, practical approach for medical professionals to optimise patient outcomes in COPD primary care.

Evaluating the effect on asthma quality of life of added reflexology or homeopathy to conventional asthma management - an investigator-blinded, randomised, controlled parallel group study.

BACKGROUND: Asthma is a common chronic disease worldwide without any known cure. Despite remarkable improvement in asthma treatment, better education and guideline implementation strategies, there is growing interest in using complementary and alternative medicine, like reflexology and homeopathy. However, evidence supporting the effectiveness of homeopathy and reflexology in asthma treatment is not available. OBJECTIVE: The aim of this study was to evaluate the effect of reflexology and homeopathy as adjunctive therapies in asthma. METHODS: In a single centre, randomised, investigator blinded, controlled study 86 asthma patients were enrolled. They were assigned to one of three study groups (conventional treatment alone or conventional treatment with addition of either homeopathy or reflexology). All patients received their asthma treatment during the study and were followed as usual by their general practitioner. The study assignment group of individual patients were blinded to the investigators, who made the clinical evaluation of asthma control. The primary outcome was the change in the asthma quality of life questionnaire (AQLQ) scores after 26 weeks. Secondary outcomes included asthma control questionnaire, EuroQol, forced expiratory volume in 1 sec, morning and evening peak expiratory flow, asthma symptoms, rescue medication use, and total medication score. RESULTS: Minor improvements in the AQLQ score were observed in all three groups. However, no statistically significant changes in AQLQ scores were seen within or between groups. Likewise, secondary outcomes did not differ between groups. CONCLUSIONS: In this study, the addition of homeopathy or reflexology to conventional treatment did not result in improved quality of life in asthma.

Compliance in subcutaneous and sublingual allergen immunotherapy: A nationwide study.

INTRODUCTION: Allergic rhino-conjunctivitis is a highly prevalent condition. In moderate to severe cases, allergen immunotherapy (AIT) is a cost-effective therapeutic option. Previous data have reported a large difference in treatment compliance of subcutaneously (SCIT) and sublingually (SLIT) administered AIT. METHODS: By use of the unique civil registration number assigned to all Danish citizens and the Danish National Health Service Prescription Database, compliance rates of all patients prescribed with grass pollen AIT from January 1998 until December 2016 were analysed annually during the three-year treatment period. RESULTS: The male/female ratio was close to 1:1 in SCIT, while SLIT was more frequently used by men. A large proportion of users was children or adolescents (32% and 45%, SCIT and SLIT, respectively). Compliance of both subcutaneous and sublingual treatment gradually fell each year; compliance in year 3 was 57% and 53% for subcutaneous and sublingual treatment, respectively. Compliance of grass pollen sublingual treatment was also analysed each year after registration on the Danish market. Compliance significantly increased following the introduction and stabilised on a relatively high level. CONCLUSION: Based on previous studies, we hypothesised that AIT compliance would be low, especially in SLIT. However, in Denmark, compliance in SCIT and SLIT was almost similar, and the majority of patients completed the three-year treatment period with a compliance in the last quintile.

The risk of osteoporosis in patients with asthma.

It is well-known that use of continuous systemic corticosteroids (SG) affects bone metabolism, bone mineral density (BMD), and ultimately increases the risk of osteoporosis. In patients with asthma, on the other hand, the effects of long-term high-dose inhaled corticosteroids (ICS) on BMD and risk of osteoporotic fractures is controversial. The reasons for this inconsistency could be explained by the fact that only few long-term studies investigating the effect of ICS in patients with asthma exist. The studies are characterized by different study designs and duration of ICS exposure, small study populations, and differences between the used ICS. The aim of this article is to unravel which factors, if any, that contribute to an increased risk of osteoporosis in patients with asthma and to summarize the evidence regarding adverse effects of ICS on bone metabolism, BMD and osteoporotic fractures in patients with asthma.

The impact of reflexology and homeopathy added to conventional asthma treatment on markers of airway inflammation - a randomised study.

Background: Asthma is a common chronic airway disease associated with hyperresponsiveness and airway inflammation. Anti-inflammatory medication especially inhaled corticosteroids are important for control of airway inflammation, decrease of airway hyperresponsiveness and lung function variability, reduce asthma symptoms, and improve lung function as well as quality of life. Most studies investigating the influence of complementary and alternative medicine (CAM) in asthma measure clinical effectiveness, but only few evaluate the impact on markers of airway inflammation. Objective: The aim of this study was to investigate the effect of reflexology and homeopathy added to conventional treatment on different markers of airway inflammation in asthma. Methods: Eighty-four patients with asthma were randomized to receive conventional treatment alone or conventional treatment with addition of homeopathy or reflexology in a single center, investigator blinded, controlled, one-year trial. During the study period, patients regularly consulted their general practitioner for evaluation and asthma treatment. At randomization, and after 6 and 12 months, methacholine challenge test and measurement of exhaled nitric oxide were performed. Blood samples were collected for eosinophil count and measurement of serum eosinophil cationic protein. Results: No significant differences between groups for any of the inflammatory markers were demonstrated. Methacholine responsiveness improved in all three groups but improvements were not statistically significant within and between groups. Conclusions: This randomized controlled study of reflexology and homeopathy failed to show significant improvement on selected markers of inflammation and airway hyperresponsiveness in asthma.

Tele-delivered mindfulness-based cognitive therapy in chronic obstructive pulmonary disease: A mixed-methods feasibility study.

INTRODUCTION: Mindfulness-based cognitive therapy has been shown to reduce psychological distress in chronic obstructive pulmonary disease, but uptake and attendance rates of hospital-based, face-to-face mindfulness-based cognitive therapy are low. The present mixed-methods study evaluates the clinical feasibility of home-based, tele-delivered mindfulness-based cognitive therapy in chronic obstructive pulmonary disease. METHODS: Eight patients with chronic obstructive pulmonary disease (mean age: 72.6 years; 50% female) received a standardised eight-week mindfulness-based cognitive therapy programme delivered via home-based video-conferences in groups of four. Feasibility in relation to (a) clinical change, (b) attendance and (c) instructor-patient working alliance were evaluated with questionnaires and semi-structured interviews. RESULTS: Statistically non-significant reductions in psychological distress (Cohen's d = 0.504; p = 0.399) and physical health status impairment (d = 0.743; p = 0.156) were observed from pre- to post-intervention. Participant narratives about clinical outcomes focused on changes in how to relate to unpleasant sensations, i.e. through attentional flexibility, taking a pause and acceptance. The average attendance rate was 7.5 (standard deviation = 0.8) out of eight sessions and no participants dropped out. The tele-based format appeared to accommodate participants' planning difficulties and promoted their ability and wish to participate. Although participant narratives suggested the tele-based format to be a barrier to developing a trusting and safe therapeutic environment, working alliance questionnaire scores were comparable to those found for face-to-face mindfulness-based cognitive therapy. DISCUSSION: The preliminary results indicate that tele-delivered mindfulness-based cognitive therapy is a clinically feasible intervention in chronic obstructive pulmonary disease. Future large-scale, randomised controlled trials testing its efficacy on the outcomes of psychological distress and physical health status should include analyses of potential mediators and moderators of the effect as well as and careful monitoring of attendance and adverse events.

Mindfulness-based cognitive therapy in COPD: a cluster randomised controlled trial.

A considerable proportion of patients with chronic obstructive pulmonary disease (COPD) entering pulmonary rehabilitation (PR) report psychological distress, which is often accompanied by poor physical health status. Mindfulness-based cognitive therapy (MBCT) has been shown to improve psychological and physical outcomes in other chronic diseases. We therefore evaluated the efficacy of MBCT as an add-on to a standard PR programme in COPD.COPD patients eligible for PR were cluster randomised to receive either an 8-week, group-based MBCT programme as an add-on to an 8-week PR programme (n=39), or PR alone (n=45). The primary outcomes of psychological distress and physical health status impairment were measured with the Hospital Anxiety and Depression Scale (HADS) and the COPD Assessment Test (CAT) before randomisation (T1), mid- (T2) and post-intervention (T3), and at 3 (T4) and 6 (T5) months' follow-up .A statistically significant time×arm effect was found for the HADS (Cohen's d=0.62, 95% CIs (d)=0.18-1.06, p=0.010). The treatment effect on the CAT failed to reach statistical significance (d=0.42, 95% CIs (d)=-0.06-0.90, p=0.061).MBCT showed a statistically significant and durable effect on psychological distress, indicating that MBCT may be an efficacious add-on to standard PR programmes in COPD.

Dietary beetroot juice - effects on physical performance in COPD patients: a randomized controlled crossover trial.

BACKGROUND AND OBJECTIVE: Dietary beetroot juice (BR) supplementation has been shown to reduce the oxygen (O2) consumption of standardized exercise and reduce resting blood pressure (BP) in healthy individuals. However, the physiological response of BR in chronic obstructive pulmonary disease (COPD) remains controversial. The objective was to test exercise performance in COPD, supplementing with higher doses of BR for a longer duration compared to previous trials in this patient group. METHODS: Fifteen COPD patients consumed concentrated BR (2×70 mL twice daily, each containing 300 mg nitrate) or placebo (PL) (2×70 mL twice daily, nitrate-negligible) in a randomized order for 6 consecutive days. On day 7, participants consumed either BR or PL 150 min before testing. BP was measured before completing 6-minute walk test (6MWT) and two trials of submaximal cycling. The protocol was repeated after a minimum washout of 7 days. RESULTS: Plasma nitrite concentration was higher in the BR condition compared to PL (P<0.01). There was no difference between the BR and PL conditions regarding the covered distance during the 6MWT (mean ± standard error of the mean: 515±35 m (BR) vs 520±38 m (PL), P=0.46), O2 consumption of submaximal exercise (trial 1 P=0.31 vs trial 2 P=0.20), physical activity level (P>0.05), or systolic BP (P=0.80). However, diastolic BP (DBP) was reduced after BR ingestion compared to baseline (mean difference: 4.6, 95% CI: 0.1-9.1, P<0.05). CONCLUSION: Seven days of BR ingestion increased plasma nitrite concentrations and lowered DBP in COPD patients. However, BR did not increase functional walking capacity, O2 consumption during submaximal cycling, or physical activity level during the intervention period.
