The Efficacy of Bronchial Thermoplasty for Severe Persistent Asthma: The First National Experience.

There is an unmet need for new therapies in severe persistent asthma. Bronchial thermoplasty is a bronchoscopic procedure which employs radiofrequency energy to reduce airway smooth muscle and has been demonstrated to improve symptomatic control in severe persistent asthma in other populations. Seven patients have completed bronchial thermoplasty at a tertiary referral centre in Ireland. Asthma Control Test scores and data on hospitalisations, exacerbations, maintenance corticosteroid requirements, rescue bronchodilator use and peak expiratory flow rate (PEFR) were compared one year before and one year post treatment. Significant improvements were demonstrated in mean Asthma Control Test scores, from 8.9 to 14.7 (p = 0.036). Trends towards improvement were seen in mean hospitalisations (respective values for total in 12 month period 5.0, 0.9; p = 0.059) and PEFR (181.4 l/min, 280 l/min respectively; p = 0.059). These data support the use of bronchial thermoplasty in severe persistent asthma in the Irish population.

Palliative Subcutaneous Terbutaline Infusion in Severe Asthma.

Continuous subcutaneous infusion of terbutaline (CSIT) has been shown to improve asthma control. As an adjunct to standard asthma pharmacotherapy, 3-12mg/day of CSIT can stabilise asthmatic symptoms, reduce hospitalisations and reduce corticosteroid need1,2. Asthmatics who demonstrate a wide diurnal variability in their peak-flows (>40%), termed brittle asthmatics tend to benefit the most from this therapy3. CSIT can have adverse effects and should only be used in specialist respiratory centres.

Qualitative effects of omalizumab on concomitant IgE-mediated disease in a severe asthmatic population: a real life observational study.

INTRODUCTION: Omalizumab is a recombinant humanized monoclonal antibody (anti-IgE) licensed for use in GINA 5 asthma or for chronic idiopathic urticaria. Many patients with asthma have concomitant allergic diseases such as dermatitis and sinusitis. IgE is also implicated in allergic-bronchopulmonary disease (ABPA). In addition, extreme sensitivity to allergen can prevent the initiation of allergen immunotherapy. AIM: The aim of this study was to assess the efficacy of omalizumab on symptoms of concomitant non asthmatic IgE-mediated allergic disease in a population of severe GINA 5 in a real life observational setting. DESIGN: This study is a retrospective, observational study assessing patients reported allergic, non-asthmatic symptom response to omalizumab treatment. METHODS: Fifty-six severe asthmatics treated with omalizumab were studied. Thirty-seven patients had concomitant rhino-sinusitis, 13 had dermatitis and 4 ABPA. Subjects were asked to grade the improvement in their symptom scores on an analogue scale from 0 (no response) to 10 (excellent response). RESULTS: Mean improvement from baseline was 5 and 1.8 in patients with allergic rhino-sinusitis and dermatitis, respectively. Mean improvement from baseline in respiratory symptoms in patients with ABPA was 4.0. CONCLUSIONS: The results from our study suggest that omalizumab may have a role in allergic disease outside of its current license.

The Value of the Combined Assessment of COPD in Accurate Characterization of Stable COPD.

There is evidence showing a tendency to upgrade COPD severity previously staged with spirometric-based GOLD (GOLD 1234) when using the new GOLD combined disease assessment (GOLD ABCD). The aim of our study was to compare the GOLD 1234 classification in a population of stable COPD patients with the GOLD ABCD classification to determine whether stable COPD was upgraded when using this new classification. After an observational study of a stable COPD cohort (n = 112), 61 patients (54.5%) had an increase in their COPD severity when moving from the old GOLD 1234 classification to the current GOLD ABCD assessment (p < 0.01). 42 patients (37.5%) had no change in severity of COPD. 9 patients COPD were assessed to be better on using GOLD ABCD. This study highlights previously missed high-risk patients when reviewing stable COPD. Continued incorporation of GOLD ABCD will translate into better evidence-based management.

The Efficacy of COPD Outreach in Reducing Length of Stay and Improving Quality of Life.

COPD exacerbations results in prolonged hospitalisation, re-admissions, reduces health-related quality of life (HRQoL) and increases mortality. The study aimed to assess the efficacy of a COPD Outreach service in reducing average length of stay (ALOS), reducing readmissions within 90 days of admission, improving HRQoL and reducing mortality among COPD patients with acute exacerbations (AECOPD). AECOPD data for a 2 year period commencing September 2011 was analysed. The COPD Assessment test (CAT) quantified HRQoL at enrolment and 6 weeks post Outreach. COPD Outreach had an ALOS of 2.47 days compared to ALOS 8.59 days and 8.5 days for all AECOPD before and during an operational COPD Outreach. Re-admission rates among patients enrolled in COPD Outreach were 36.3%. CAT improved from mean 19.3 to 13.5. Mortality was 4.9% among Outreach patients and 2.5% for overall AECOPD in 2012-2013. COPD Outreach reduced ALOS and improved HRQoL for selected patients with AECOPD. It did not reduce re-admissions or mortality.

Safety of Grass Pollen Sublingual Immunotherapy for Allergic Rhinitis in Concomitant Asthma.

Seasonal allergic rhinitis (AR) occurs predominantly as a result of grass pollen allergy. Grass pollen sublingual immunotherapy (SLIT) has been proven effective in treating AR1. SLIT is currently licensed for use in AR with concomitant stable mild asthma. There is evidence that SLIT improves asthma control when primarily used to treat AR2. The aim was to assess the safety of SLIT in patients with severe seasonal allergic rhinitis who have co-existing stable mild asthma. The secondary aim was to determine whether asthma control improved post SLIT. There was no deterioration in asthma control after 6-36 months of SLIT. 27/30 (90%) patients' asthma control remained stable or indeed improved (p < 0.021). Of this 15 (50%) patients' asthma improved. There was no statistically significant change in their asthma pharmacotherapy after SLIT (p = 0.059). In conclusion, grass pollen SLIT is safe and can potentially treat dual allergic rhinitis- mild asthmatic patients.

The use of the Simpson Angus Scale for the assessment of movement disorder: A training guide.

The Simpson Angus Scale is commonly used for the assessment of Parkinsonian Movement Disorder related to psychiatric drug treatment. The authors present a practical guide to the use of the scale to assist both the learner and the teacher.
