Refractory breathlessness is a devastating symptom in chronic obstructive pulmonary disease (COPD). Symptom-focused breathlessness services, involving palliative care teams, offer individualized support but are not yet widely available for people with nonmalignant disease among which COPD. Our primary aim was to demonstrate the feasibility of setting up a breathlessness service specifically for COPD patients within a respiratory outpatient clinic. Our secondary aims were to assess how many sessions patients need to complete the intervention; to obtain an indication of effect size (on the Chronic Respiratory Questionnaire (CRQ), subset mastery domain); and to evaluate patient and professional satisfaction. We conducted a non-randomized single-center feasibility study. Participants had COPD and refractory breathlessness. During at least one session with a respiratory nurse and a pulmonologist, and one session with a physiotherapist, patients learned non-pharmacological interventions to manage breathlessness. Of 34 screened patients, 19 were included. All completed the intervention. A median of two clinical visits and two telephone calls were needed to complete the intervention. The mean improvement of 1.55 in CRQ, mastery domain, significantly exceeded the clinically important difference of 0.5. The service was rated as excellent by the eight patients who completed the survey. The health professional team gave positive feedback on the experience of delivering the intervention. Delivery of a breathlessness service for COPD outpatients with refractory breathlessness appears feasible, easy to implement in a respiratory outpatient clinic, and has the potential to be effective. A randomized controlled clinical trial is needed to test effectiveness and cost-effectiveness in this context.

Quality-of-life (QOL) in patients with respiratory illness is a topic of increasing interest to clinicians and researchers. In a multicentre trial, which studies the long-term effects of three medication regimens (beta-agonist plus either placebo, anticholinergic agent or corticosteroid, all by inhalation) in patients with chronic nonspecific lung disease ((CNSLD): asthma and chronic obstructive pulmonary disease (COPD)), quality-of-life was included as an additional outcome measure. We wanted to provide a baseline assessment of quality-of-life in 274 adult patients with a mild to moderate degree of CNSLD. Quality-of-life was measured using a set of six standardized tests: Anxiety, Depression and Sleep Disorders, Optimism and Stigma, and Activities of Daily Living were assessed via scales with adequate validity and reliability, as established in previous work in Dutch patients with CNSLD. We found that quality-of-life was mildly impaired in these patients. Although differences with a reference group were present throughout, these were not significant, probably due to selection of relatively young, clinically stable, and highly motivated patients for our study. Quality-of-life scores showed higher correlation coefficients (0.20 < r < 0.38) to symptom scores than did results of pulmonary function tests (r < 0.015). In logistic regression models, absence from work and hospitalizations due to CNSLD were partly determined by quality-of-life scores.(ABSTRACT TRUNCATED AT 250 WORDS)

Reduction of exacerbation frequency plays an increasingly important role in interventions in chronic obstructive pulmonary disease (COPD). To reduce this frequency efficiently, patients at risk for frequent exacerbations need to be identified.The objective of the study was to identify predictors for frequent exacerbations from multiple domains of COPD during a stable phase of the disease. Data of multiple domains of COPD were collected from 121 patients with moderate to severe COPD. Patients were divided into infrequent (2 exacerbations per year) and frequent (≥2 exacerbations) exacerbators.St. George's Respiratory Questionnaire (SGRQ) total score and a course of oral corticosteroid within 3 months prior to the study together predicted best whether patients would be infrequent or frequent exacerbators over the course of the next year. Each unit increase in total SGRQ score was associated with a 3% higher risk of being a frequent exacerbator [odds ratio (OR) = 1.03; 95% confidence interval (CI): 1.00-1.06; P = 0.047]. Patients who received a course of oral corticosteroids in the period of 3 months prior to the study had a three-fold increased risk of being a frequent exacerbator (OR = 3.17; 95% CI: 1.20-8.34; P = 0.02). Furthermore, we observed that a sizable number of patients switched from being a frequent to an infrequent exacerbator and vice versa.Health-related quality of life and a course of oral corticosteroid in the past 3 months are the best predictors of future exacerbator status. The predictive value of the model is, however, still insufficient. Furthermore, our data suggest, in contrast to previous observations, that exacerbation frequency is not a constant feature.

Bronchiectasis is usually a complication of previous lower respiratory infection, and causes chronic cough and copious production of sputum, which is often purulent. Bronchiectasis may cause signs of chronic obstructive pulmonary disease. It can also be associated with cystic fibrosis and other congenital disorders, foreign body inhalation, and other causes of lung damage.We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments in people with bronchiectasis but without cystic fibrosis? We searched: Medline, Embase, The Cochrane Library and other important databases up to July 2007 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We performed a GRADE evaluation of the quality of evidence for interventions.We found 16 systematic reviews, RCTs, or observational studies that met our inclusion criteria.In this systematic review we present information relating to the effectiveness and safety of the following interventions: anticholinergic therapy, bronchopulmonary hygiene physical therapy, exercise or physical training, hyperosmolar agents (inhaled), leukotriene receptor antagonists, methyl-xanthines (oral), mucolytics (bromhexine or deoxyribonuclease), prolonged-use antibiotics, beta(2) agonists, steroids (inhaled, oral), and surgery.

There is a large variability in clinical response to corticosteroid treatment in patients with asthma. Several markers of inflammation like eosinophils and eosinophil cationic protein (ECP), as well as exhaled nitric oxide (NO), are good candidates to predict clinical response.We wanted to determine whether we could actually predict a favourable response to inhaled corticosteroids in individual patients.One hundred and twenty patients with unstable asthma were treated with either prednisolone 30 mg/day, fluticasone propionate 1000 microg/day b.i.d. or fluticasone propionate 250 microg/day b.i.d., both via Diskhaler. They were treated during 2 weeks, in a double-blind, parallel group, double dummy design. We measured eosinophils and ECP in blood and sputum, and exhaled nitric oxide as inflammatory parameters before and after 2 weeks in order to predict the changes in forced expiratory volume in 1 s (FEV1), provocative concentration of methacholine causing a 20% fall in FEV1 (PC20 Mch), and asthma quality of life (QOL). Secondly, to test whether these results were applicable in clinical practice we determined the individual prediction of corticosteroid response.We found that changes in FEV1, PC20 Mch and QOL with corticosteroids were predominantly predicted by their respective baseline value and to a smaller extent by eosinophils in blood or sputum. ECP, measured in blood or sputum, was certainly not better than eosinophils in predicting clinical response to corticosteroids. Smoking status was an additional predictor for change in FEV1, but not for change in PC20 Mch or QOL. Prediction of a good clinical response was poor. For instance, high sputum eosinophils (or = 3%) correctly predicted an improvement in PC20 Mch in only 65% of the patients.Our findings show that baseline values of the clinical parameters used as outcome parameters are the major predictors of clinical response to corticosteroids. Eosinophil percentage in blood or sputum adds to this, whereas ECP provides no additional information. Correct prediction of clinical response in an individual patient, however, remains poor with our currently used clinical and inflammatory parameters.

Although most patients with obstructive airways disease show some amelioration with long-term inhaled corticosteroid therapy, the extent of improvement may vary considerably between patients. Patients with mild to moderately severe obstructive airways disease (asthma and COPD) were selected if provocative concentration producing a 20% fall in forced expiratory volume in one second (PC20) < or = 8 mg.ml-1, and forced expiratory volume in one second (FEV1) < 95% confidence intervals (CI) of predicted normal. The independent influences of baseline PC20FEV1, inspiratory vital capacity (IVC), bronchodilator response, smoking habits, and allergy both on the "immediate" (within 3 months) response in FEV1 and the change in long-term (from 3 months onwards) slope of FEV1 with inhaled corticosteroids were analysed. Patients had a larger "immediate" improvement in their FEV1 with inhaled corticosteroids with each doubling doses lower PC20, with each ten-fold higher immunoglobulin E (IgE), and if they did not smoke. Total IgE proved a better independent predictor of "immediate" response than specific IgE for house dust mite, skin tests, or blood eosinophils. A more favourable long-term slope of FEV1 was predicted by a larger baseline bronchodilator response, but not by smoking. In conclusion, PC20, total IgE, and smoking habits are independent predictors of immediate treatment response to inhaled corticosteroids. Bronchodilator response is the single independent predictor of changes in long-term slope of FEV1 with corticosteroid treatment.

We wanted to compare the efficacy and safety of fluticasone propionate, a new topically active inhaled corticosteroid, to that of high dose beclomethasone dipropionate, in severe adult asthma. Patients currently receiving between 1.5-2.0 mg.day-1 of an inhaled corticosteroid were treated for six weeks in a double-blind, randomized, parallel group study with 1 mg.day-1 fluticasone propionate (n=82), or 2 mg.day-1 beclomethasone dipropionate (n=72). Mean morning peak expiratory flow rates (PEFR) increased from 303 to 321 l.min-1 with fluticasone propionate, and from 294 to 319 1.min-1 with beclomethasone dipropionate. There was an increase in evening PEFR, asthma symptoms improved, and rescue beta2-agonist use decreased for both treatment groups. None of these differences between treatments were statistically significant However, diurnal variation was significantly reduced with fluticasone propionate, when compared with beclomethasone dipropionate (difference = 7 l.min-1; p=0.038). Clinic lung function also improved with both treatments and, apart from % predicted PEFR, which showed no difference after beclomethasone dipropionate but increased from 73 to 78 % with fluticasone propionate, there were no differences between treatments. Forced expiratory volume in one second (FEV1) increased with both treatments. The geometric mean plasma cortisol concentration rose after treatment with fluticasone propionate (from 293 to 309 nmol.l-1) and fell after beclomethasone dipropionate (from 256 to 224 nmol.l-1); the difference between treatments was significant. The incidence of adverse events was low in both treatment groups. In conclusion, 1 mg-day-1 fluticasone propionate was as effective as 2 mg-day-1 beclomethasone dipropionate in the control of severe asthma. However, adrenal function was affected less by fluticasone propionate, which gives it a better overall safety profile. This study, therefore, demonstrates the increased therapeutic potential of fluticasone propionate over beclomethasone dipropionate in severe asthma.

OBJECTIVE: Reporting the results of combined heart-lung transplantation in the University Medical Center Groningen (UMCG), the Netherlands. DESIGN: Retrospective study. METHOD: Data were retrieved of patients who underwent a combined heart-lung transplantation in the UMCG between December 1996 and December 2007. Demographic, clinical and other relevant characteristics were recorded, as well as post-transplantation morbidity and mortality. RESULTS: The study group consisted of 14 patients (3 men and 11 women) with a mean age of 41 years. Indications for heart-lung transplantation were: congenital heart disease complicated by pulmonary hypertension (6 patients), idiopathic pulmonary hypertension with severe right ventricle failure (4 patients), lung fibrosis with severe right ventricle failure (1 patient), cystic fibrosis with systolic left ventricle failure (1 patient), pulmonary hypertension after thoracic radiation and chemotherapy (1 patient) and re-transplantation after lung-transplant failure (1 patient). The mean waiting time prior to operation was approximately 1.5 years. 9 of the 14 patients (64%) underwent such a marked clinical deterioration during the waiting period that they were given a 'very high urgency status' for transplantation. Almost half of patients became dependent on supplementary intravenous inotropics during the waiting period. At the end of the study 6 of the 14 patients (43%) were alive, with a mean survival period of 58 months (range: 6-132). Infection was the cause of death in 4 of the 8 patients. Of the 8 deceased patients, 4 were underweight preoperatively (BMI < 18.5 kg/m2) and were cachectic. This was the case in only 1 of the 6 surviving patients. CONCLUSION: A combined heart-lung transplantation is a rare operation in the Netherlands. The waiting time in this study was long and the post-transplantation mortality was high. Underweight (cachexia), a sign of a poor clinical condition, appears to be associated with mortality.

World COPD day is an annual event intended to increase awareness of chronic obstructive pulmonary disease. During this day, in November 2006, free spirometry testing was offered to the public in approximately 100 places including hospitals, pharmacies, offices of GPs and tents on main squares throughout the Netherlands. The objective of this action is laudable. However, screening for COPD is generally considered ineffective. Furthermore, the application of a fixed ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) (FEV1/FVC0.70) as recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) to detect airflow limitation, required for a diagnosis of COPD, may lead to underdiagnosis of COPD in the young and to overdiagnosis in the elderly. In addition, spirometry was generally performed without bronchodilation, thus further increasing the likelihood of a false-positive diagnosis ofCOPD. Smoking cessation is important in halting the progression of COPD. Therefore, identifying smokers at risk for developing COPD seems a logical reason for screening or case finding for COPD. However, it has not been clearly demonstrated that early detection of COPD may contribute to improved smoking cessation rates. Also, smokers with normal spirometry may be led to believe that smoking has no adverse effects on their health. Therefore, a different strategy should be adopted to increase awareness of COPD on the next World COPD day.

Airways obstruction and airways hyperresponsiveness are two dominant features in patients with chronic nonspecific lung disease (asthma and chronic obstructive pulmonary disease (COPD)). We set up a study to determine whether long-term (3 yrs) therapeutic intervention directed at airways obstruction and hyperresponsiveness is superior to one directed at airways obstruction alone. Patients were selected on functional criteria (age, baseline forced expiratory volume in one second (FEV1), and airways hyperresponsiveness) and, furthermore, extensively characterized by history, smoking habits, allergy, reversibility of airways obstruction and quality of life. The methodology and practical problems of setting up this large multicentre study are outlined, together with an analysis of baseline data. Standardization of methods and techniques and recruitment of patients required much effort, recruitment taking about twice as long as expected. A 3 month feasibility study allowed us to eliminate minor problems in the protocol. Over a 16 month period, 274 adult patients (18-60 yrs) from the out-patient clinics of six university centres entered the study; 99 met the diagnostic criteria for asthma, 51 for COPD, 88 for asthmatic bronchitis, and 36 could not be classified. Their mean (SD) FEV1% pred was 65.1 (15.2)%. Their geometric mean provoking concentration of histamine producing a 20% fall in FEV1 (PC20 histamine) was 0.28 mg.ml-1. In a multiple regression analysis, more severe airways hyperresponsiveness was associated with lower prechallenge FEV1% pred (p less than 0.0001), higher pack-years of smoking (p = 0.0099), blood eosinophil count (p = 0.0004), skin test reactivity (p = 0.0047) and with female sex (p = 0.0302). We conclude that setting up long-term multicentre trials in chronic nonspecific lung disease (CNSLD) is feasible and that these may offer valuable information on treatment and outcome of the disease.

Background: The relationships between allergic symptoms after exposure to house dust, allergy parameters (skin test to house dust mite [HDM], total IgE, HDM-specific IgE, and blood eosinophil counts), and several confounding variables (age, sex, smoking habits, and airway hyperresponsiveness) were evaluated in 235 patients with asthma and chronic obstructive pulmonary disease (COPD). Results: Skin tests had higher diagnostic value (sensitivity plus specificity) for symptomatic allergy than specific IgE (1.45 versus 1.36) or total IgE (1.16). The other allergy parameters gave no additional information on symptoms once the skin test was known. Expressing the skin test relative to the histamine control proved slightly better than uncorrected wheal size, but this probably has limited clinical value. The best cutoff level for a positive skin test was 0.7 when the histamine wheal size was accounted for by division, -6 mm when subtraction was used, and 7 mm for absolute wheal size. These cutoff levels proved equally applicable in various subgroups of patients with asthma and COPD. Only the skin test and female sex were independent predictors of allergic symptoms. Conclusion: We conclude that skin tests to HDM are better predictors for clinical allergy than total or specific IgE levels and eosinophil count, and that they are applicable in most patients with asthma and with COPD.

Asthma is characterised by chronic airway inflammation and variable airway obstruction. Maintenance therapy with inhaled corticosteroids and short-acting beta2 agonists on demand constituted the cornerstone of asthma management for many years. Since introduction of the long-acting form, beta2 agonists are currently also used as maintenance therapy. beta2 agonists and corticosteroids have complementary and synergistic effects in vitro and the combination also has increased efficacy clinically. The combination of long-acting beta2 agonists and inhaled corticosteroids is the treatment of choice in patients with moderately severe asthma whose symptoms persist despite inhalation of a corticosteroid. Currently, the combinations fluticasone-salmeterol and budesonide-formoterol are commercially available in one inhaler. Studies of these combined preparations are based on two contradictory treatment strategies: one in which the dosage is increased gradually in a controlled manner, and one in which a variable dose is added to a maintenance regime. Both strategies seem more effective than fixed low dosages of the same preparations. A well-founded choice between the two strategies cannot be made, if only due to the lack of knowledge regarding the effects of these strategies on treatment compliance, airway remodelling, side effects and costs.

Background. The morbidity from obstructive airways disease (asthma and chronic obstructive pulmonary disease) is considerable, and the mortality rate is rising in several countries. It has been hypothesized that long-term improvement in prognosis might result from vigorous bronchodilator or antiinflammatory therapy. Methods. In a multicenter trial we compared three inhalation regimens in which a beta2-agonist (terbutaline, 2000 mug daily) was combined with a corticosteroid (beclomethasone, 800 mug daily), an anticholinergic bronchodilator (ipratropium bromide, 160 mug daily), or placebo. Patients with airways hyperresponsiveness and obstruction who were 18 to 60 years old were followed for 2 1/2 years. Results. Of the 274 patients enrolled, 56 percent had allergies. The mean forced expiratory volume in one second (FEV1) was 64 percent of the predicted value. The mean PC20 (the concentration of inhaled histamine causing a 20 percent decrease in FEV1, a measure of hyperresponsiveness) was 0.26 mg per milliliter. Withdrawal from the study, due mainly to pulmonary symptoms, was less frequent in the corticosteroid group (12 of 91 patients) than in the anticholinergic-drug group (45 of 92 patients) or the placebo group (44 of 91 patients; P Conclusions. The addition of an inhaled corticosteroid - but not an inhaled anticholinergic agent - to maintenance treatment with a beta2-agonist (terbutaline) substantially reduced morbidity, hyperresponsiveness, and airways obstruction in patients with a spectrum of obstructive airways disease.

The objective of this study was to determine the costs and effects of combined bronchodilator and antiinflammatory therapy. In a 2.5-yr randomized controlled study, combined beta(2)-agonist/corticosteroid therapy (BA + CS) and combined beta(2)-agonist/anticholinergic therapy(BA + AC) were compared with beta(2)-agonist/ placebo therapy (BA + FL). Included in the study were 274 patients 18 to 60 yr of age with moderately severe obstructive airways disease. The main clinical endpoints were lung function, hyperresponsiveness, restricted activity days, and symptom-free days. The economic endpoints were the costs of health care utilization. Compared with BA + FL, BA + CS led to significant improvements in FEV(1), PC20, and symptom-free days. BA + AC did not differ from BA + PL in this respect. The respective annual acquisition costs of BA + CS, BA + AC, and BA + PL were 532 US$, 277 US$, and 156 US$. Thus, BA + CS costs 376 US$ more than BA + FL. However, compared with BA + PL therapy, BA + CS led to statistically significant savings in other health care costs of about 175 US$ (95% CI from 46 to 303 US$). Thus, more than half of the additional costs of adding the inhaled corticosteroid are compensated for by a reduction in the costs of other health care services. Overall, inhaled corticosteroids lead to a small but net increase in health care costs of 201 US$ per patient per year. The incremental cost-effectiveness ratio of BA + CS compared with BA + PL ranges from 200 US$ per 10% increase in FEV(1) to 5 US$ per symptom-free day gained. In order to reach net societal savings the economic benefits of increased productivity due to inhaled corticosteroids have to be valued higher than 42 US$ per day. No significant differences in health care costs were found between the BA + AC and BA + PL groups. It can be concluded that the addition of an inhaled corticosteroid to a beta(2)-agonist leads to significant benefits in respiratory function and restricted activity days, which seem to be worth the relatively low additional health care costs, whereas addition of an anticholinergic agent appears expensive and of no long-term value.

Inhaled corticosteroid has been shown to be effective in the management of asthma. However, there is a lack of studies that assess the effect of cessation after long-term treatment with inhaled corticosteroid. This question was addressed in 28 children with stable asthma, aged 11 to 18 yr of age, who had completed 28 to 36 months of treatment with inhaled corticosteroid (budesonide 200 mu g 3 times/day) and inhaled beta-2-agonist (salbutamol 200 mu g 3 times/day). The children were randomized in a 1:2 ratio in a double-blind study either to continue budesonide (n = 8) during a period of 6 months or to decrease the dose of budesonide (n = 20) within 2 months, followed by placebo for 4 months. Treatment with salbutamol 600 mu g daily was continued in both groups. Eight children from the tapering-off group withdrew, mainly due to symptoms of asthma, compared with none in the continuous treatment group. Five patients in the tapering-off group experienced exacerbations for which prednisolone was given, compared with none in the continuous treatment group. After tapering-off, symptoms of asthma and additional bronchodilator use increased, and both FEV(1)% predicted and PD20 histamine (provocation dose of histamine causing a 20% fall in FEV(1)) decreased, whereas these all remained unchanged in the group that continued treatment with inhaled corticosteroid. We conclude that in this study long-term treatment with 600 mu g budesonide daily suppressed underlying mechanisms of asthma, but did not cure the disease.
