Abstract
INTRODUCTION Bronchiectasis is a multidimensional disease associated with substantial morbidity and mortality. Two disease-specific clinical prediction tools have been developed, the Bronchiectasis Severity Index (BSI) and the FACED score, both of which stratify patients into severity risk categories to predict the probability of mortality. METHODS We aimed to compare the predictive utility of BSI and FACED in assessing clinically relevant disease outcomes across seven European cohorts independent of their original validation studies. RESULTS The combined cohorts totalled 1612. Pooled analysis showed that both scores had a good discriminatory predictive value for mortality (pooled area under the curve (AUC) 0.76, 95% CI 0.74 to 0.78 for both scores) with the BSI demonstrating a higher sensitivity (65% vs 28%) but lower specificity (70% vs 93%) compared with the FACED score. Calibration analysis suggested that the BSI performed consistently well across all cohorts, while FACED consistently overestimated mortality in 'severe' patients (pooled OR 0.33 (0.23 to 0.48), p<0.0001). The BSI accurately predicted hospitalisations (pooled AUC 0.82, 95% CI 0.78 to 0.84), exacerbations, quality of life (QoL) and respiratory symptoms across all risk categories. FACED had poor discrimination for hospital admissions (pooled AUC 0.65, 95% CI 0.63 to 0.67) with low sensitivity at 16% and did not consistently predict future risk of exacerbations, QoL or respiratory symptoms. No association was observed with FACED and 6 min walk distance (6MWD) or lung function decline. CONCLUSION The BSI accurately predicts mortality, hospital admissions, exacerbations, QoL, respiratory symptoms, 6MWD and lung function decline in bronchiectasis, providing a clinically relevant evaluation of disease severity.

Abstract
INTRODUCTION Current asthma guidelines recommend step-down of inhaled corticosteroids (ICS) to the minimum dose required for control of symptoms. AIM To determine if supervised step-down of (ICS) in the community has any effect on asthmatic inflammation. METHODS 119 Community based asthmatics underwent progressive step-down of therapy until they became unstable or reached an (ICS) dose of ≤200 μg beclomethasone dipropionate (BDP) or equivalent. Once unstable, participants stepped back up to the last stable dose of ICS. Exhaled nitric oxide (NO) and mannitol challenge were performed at the start and end of step-down. Asthma Quality of Life Questionnaire (AQLQ) and spirometry were recorded at each step-down visit. RESULTS The median (interquartile range) BDP equivalent dose was significantly higher pre vs. post step-down: 400 μg (400-800) and 250 μg (200-400) per day respectively (P < 0.05). Examination of change in PD(10) in individual patients revealed that 34% had an improvement (>+1 dd), 47% had no change (±-1 dd), and 19% had a worsening (<-1 dd). The geometric mean fold ratio in NO for pre vs. post was 0.96 (95% CI 0.87 to 1.06, P = 0.43). Mean (SEM) values for FEV(1) were 86.2% (1.51) vs. 84.5% (1.46) (P = 0.04). There was a significant improvement in AQLQ. CONCLUSIONS We have demonstrated that a significant reduction in ICS dose may be achieved in a community setting without any worsening of airways inflammation or lung function, and with an associated improvement quality of life in the majority of patients. This apparent disconnect may reflect enhanced adherence due to supervision of step-down.

Abstract
BACKGROUND Asthma and allergic rhinitis are manifestations of a single unified allergic airway, for which the best treatment is uncertain. OBJECTIVE To compare the anti-inflammatory efficacy in the unified allergic airway of combined oral mediator antagonism and combined topical steroid. METHODS Subjects with asthma and perennial allergic rhinitis entered a randomized double blind crossover study comparing montelukast 10 mg and cetirizine 10 mg to extra-fine inhaled beclomethasone 400 mcg/day and intranasal beclomethasone 200 mcg/day, each taken once daily for 2 months, after 2-week placebo washouts. Measurements were made after each washout and randomized treatment, comprising: methacholine PC20, exhaled and nasal nitric oxide, blood eosinophils and eosinophilic cationic protein, symptoms, lung and nasal function tests. RESULTS Seventeen patients completed per protocol. For PC20 and exhaled nitric oxide, only combined topical steroid produced improvements (P < 0.005) from placebo baseline. Combined steroid was superior by a 0.93 (95% CI 0.14-0.93, P < 0.05) doubling dilution difference for PC20 and a 0.99 (95% CI 0.9-15.1, P < 0.01) doubling difference for exhaled nitric oxide. Both treatments attenuated eosinophils and eosinophilic cationic protein, and reduced nasal symptoms (P < 0.05). Only steroid improved nasal nitric oxide (P=0.05) and asthma symptoms (P < 0.05). Neither treatment affected lung or nasal function tests. CONCLUSION Combined topical steroid and combined mediator antagonism both attenuated systemic inflammation in the unified allergic airway, but only the former reduced bronchial and nasal inflammatory markers. The relevance of this to exacerbations and airway remodelling needs to be defined.

Abstract
BACKGROUND Response to a single dose nasal adenosine monophosphate challenge has been used as a surrogate inflammatory marker for allergic rhinitis. Attenuation of response following intranasal corticosteroid would further validate the challenge. OBJECTIVE To assess the effect of 4 weeks of 200 mcg once daily mometasone furoate nasal spray on a simplified (single 160 mg dose) nasal adenosine monophosphate challenge. METHODS Twenty participants with persistent allergic rhinitis completed a double blind placebo-controlled crossover study. Outcome measures were the peak nasal inspiratory flow and total nasal symptoms score responses to nasal adenosine monophosphate challenge, as well as domiciliary peak nasal inspiratory flow and patient symptom diary cards. RESULTS Mometasone significantly (P < 0.05) attenuated response time profiles vs. placebo for peak nasal inspiratory flow but not total nasal symptom scores. For the maximum percentage fall this amounted to a mean difference of 9.6% (95% confidence interval 1.3-17.9%). The coefficient of variation for repeatability was 48.7%. Improvements were seen in prechallenge and domiciliary measurements of peak nasal inspiratory flow (both P < 0.05) and total nasal symptom scores (both P < 0.01). CONCLUSIONS Mometasone attenuates the peak nasal inspiratory flow response to a single 160 mg nasal adenosine monophosphate challenge. Such challenges have been shown to be sensitive to the effects of antihistamines, antileukotrienes and now nasal steroids. This further supports their application as surrogate inflammatory markers for therapeutic trials in allergic rhinitis, potentially as 20 min challenges which can be conducted in a non-hospital setting.

Abstract
BACKGROUND Addition of H(1) antagonists to intranasal corticosteroid treatment of allergic rhinitis (AR) is common in clinical practice and recommended by guidelines, despite some evidence that the additive benefits are negligible. OBJECTIVE To assess additional benefits of 5 mg levocetirizine dihydrochloride in seasonal AR patients using 200 mcg fluticasone propionate nasal spray once daily. METHODS In a double-blind placebo-controlled crossover study of 27 patients, following 2 weeks without treatment, subjects used fluticasone with levocetirizine or identical placebo for 2 weeks each. Assessments were the Juniper mini Rhinoconjunctivitis Quality-of-Life Questionnaire (mini-RQLQ), domiciliary peak nasal inspiratory flow (PNIF), total nasal symptoms (TNS) scores and nasal nitric oxide concentrations. Effects were interpreted and tested against minimal clinically important differences. RESULTS Add-on effects for levocetirizine vs. placebo excluded any clinically significant benefits: mean effects (one sided 95% confidence intervals) were mini-RQLQ -0.11 (-0.34), PNIF +0.57 (+5.23), and TNS -0.11 (-0.60). Numbers needed to treat (95% confidence intervals) by outcome were mini-RQLQ 14 (5 to 49), PNIF 4 (3-7), and TNS 3 (2-6). No significant within or between treatment effects were seen for nasal nitric oxide. CONCLUSION Contrary to current practice, the present results demonstrate that for the majority of patients, antihistamine add-on to effective nasal steroid treatment is inappropriate. Further work is required to confirm that this is also true in the most severe cases, and the available evidence needs to be put into guidelines and implemented.
