Once-daily dosing with budesonide/formoterol compared with twice-daily budesonide/formoterol and once-daily budesonide in adults with mild to moderate asthma.

Adherence to maintenance therapy is often poor in patients with asthma. Simplifying dosing regimens has the potential to improve both adherence and asthma-related morbidity. In this 12-week, randomized, double-blind, double-dummy, parallel-group study, 617 patients with mild to moderate persistent asthma (mean forced expiratory volume in 1s [FEV1] 78.5% predicted) who were not optimally controlled on inhaled corticosteroids (200-500 microg/day) were randomized to once-daily budesonide/formoterol (80/4.5 microg, 2 inhalations in the evening), twice-daily budesonide/formoterol (80/4.5 microg, 1 inhalation), or a corresponding dose of budesonide once-daily (200 microg, 1 inhalation in the evening). All patients received budesonide (100 microg twice daily) during a 2-week run-in. Changes in mean morning peak expiratory flow (PEF) were similar for od budesonide/formoterol (23.4 l/min) and twice-daily budesonide/formoterol (24.1 l/min), and both were greater than with budesonide (5.5 l/min; both P<0.001). Evening PEF, symptom-free days, reliever-free days, and asthma control days were improved with budesonide/formoterol therapy vs. budesonide (P<0.05 vs. budesonide for all variables). All treatments were well tolerated. Budesonide/formoterol administered once daily in the evening is a convenient treatment regimen that is as effective in improving asthma control as twice-daily dosing in patients with mild to moderate persistent asthma.

ESPEN Guidelines on Enteral Nutrition: Cardiology and pulmonology.

These guidelines are intended to give evidence-based recommendations for the use of enteral nutrition (EN) in patients with chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD). They were developed by an interdisciplinary expert group in accordance with officially accepted standards and are based on all relevant publications since 1985. They have been discussed and accepted in a consensus conference. EN by means of oral nutritional supplements (ONS) or tube feeding (TF) enables nutritional intake to be maintained or increased when normal oral intake is inadequate. No data are yet available concerning the effects of EN on cachexia in CHF patients. However, EN is recommended to stop or reverse weight loss on the basis of physiological plausibility. In COPD patients, EN in combination with exercise and anabolic pharmacotherapy has the potential to improve nutritional status and function. Frequent small amounts of ONS are preferred in order to avoid postprandial dyspnoea and satiety as well as to improve compliance.

[Pathogenesis of chronic obstructive pulmonary disease].

It is currently believed that the most important factor in the pathogenesis of chronic obstructive pulmonary disease (COPD) is inflammation of the small airways caused by inhaled particles and gases. In this context, a disturbance of the physiological balance between proteases and antiproteases develops that may cause lung emphysema. Moreover, oxidative stress seems to be important, as it may enhance the inflammatory reaction. The development of emphysema may also involve a loss of alveolar cells by apoptosis. Finally, several studies have indicated that a systemic inflammation is induced by COPD that may be of relevance to the development of systemic components that are observed in COPD patients.

[Clinical significance of gastrooesophageal reflux in asthma].

In clinical practice, gastrooesophageal reflux (GER) and bronchial asthma often coincide. In the case of sufficient asthma control, the asthma does not need to be taken into account when treatment of GER is being evaluated. In patients with symptomatic asthma despite adequate antiasthmatic treatment, a possible causal relationship between GER and the poor responsiveness to asthma therapy has to be considered. An algorithm to guide the diagnostic and therapeutic steps in such cases is presented.

[Acute dyspnoea].

Asthma, chronic obstructive pulmonary diseases, interstitial lung diseases and myocardial dysfunction are the leading diagnoses of patients with dyspnoea. Acute dyspnoea appears suddenly or within a few hours and is caused by a relatively limited number of conditions some of which can be life-threatening. Therefore, it is of utmost importance to identify the cause of dyspnoea immediately. Once found, the disorder is treated according to the guidelines for the underlying disease.

[Inhalation therapy with Respimat soft inhaler in patients with COPD and asthma].

Developing more effective and convenient inhalation devices for the treatment of obstructive pulmonary diseases is at least as important as designing new drugs. In recent years, existing inhalation systems have undergone many technical modifications and there have also been many new developments. All of these systems have their own particular attributes and characteristics. Two fundamentally different modes of operation are represented by propellant-driven metered-dose inhalers (pMDI) on the one hand and dry powder inhalers (DPI) on the other. However, none of the systems developed so far can be considered ideal. The Respimat Soft Inhaler (Respimat SI) was developed in the light of experience with previous systems and was launched in Germany at the beginning of 2004. The aim in developing this new type of inhaler was to avoid the well-known drawbacks typically associated with pMDI and DPI. The Respimat SI requires neither a chemical propellant nor batteries. The active ingredients are dissolved in water and the solution is atomised using mechanical energy only imparted by a spring which, when released, provides the power to force the solution through an extremely fine nozzle system. Two fine jets of liquid are produced. They converge at an optimised angle and the resulting impact generates a fine mist which is slow-moving and lasts for about 1.5 seconds; moreover, a high proportion of the droplets fall into the fine particle fraction. All of these features allow excellent lung deposition and reduced oropharyngeal deposition. Coordination between actuation and inhalation is less critical as compared with pMDI due to the fact that the mist is both slow-moving and long-lasting. A further advantage is that the mist is generated independently of the patient's inspiratory flow. The Respimat SI meets the requirements for an ideal inhaler better than any other previous device and must therefore be regarded as a significant new development.

[Nocturnal long-term recording of breath sounds in patients with bronchial asthma -- a reasonable diagnostic option?].

Alterations in normal breath sounds are an important indication of pathophysiological processes in the bronchial system and the lung. In the presence of non-specific symptoms like dyspnea, wheezing or cough while sleeping it seems reasonable to make a nocturnal long-term recording of breath sounds. Thus specific auscultation phenomena can be recorded qualitative and particularly quantitative in the course. A mobile recording system provides a non-invasive monitoring at home which is independent of vigilance. Furthermore it can be used for follow-up examinations of medical interventions.

TNF-alpha-, TNF-beta-, IL-6-, and IL-10-promoter polymorphisms in patients with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a major health problem. The disease is driven by abnormal inflammatory reactions in response to inhaled particles and fumes. Therefore, inflammatory mediators are postulated to be of distinct importance. In the present case-control study, we investigated interleukin (IL)-promoter polymorphisms known to correlate with altered transcription levels of their gene products in patients with COPD. We analyzed tumor necrosis factor-alpha (TNF-alpha)-308, TNF-beta-intron1-252, IL-6-174, IL-10-819, and IL-10-1082 polymorphisms in 469 individuals using restriction fragment length polymorphism-based converted polymerase chain reaction. The study population consisted of 113 patients with COPD based on chronic bronchitis, divided into subgroups by severity (I degrees -III degrees ), 113 matched hospitalized individuals suffering from severe coronary heart disease without pulmonary disease (age-, sex-, and smoking-matched control group), and 243 healthy individuals (population control group). The matched analysis showed no significant differences in genotype distribution of all tested polymorphisms between the matched controls and the COPD patients. However, comparison with the population controls revealed significant differences in IL-10-1082 A/G genotype frequencies (P = 0.0247 for the whole COPD group, P = 0.009 for smokers only), with the genotypes carrying the G allele more common in the COPD cases [odds ratio (OR) = 1.66, 95% confidence interval (CI) 1.01-2.75; P = 0.046]. Interestingly, this shift toward more G alleles was even more pronounced in the matched control group (OR = 2.55, 95% CI 1.47-4.41; P = 0.0007), suggesting both presented groups share corresponding underlying mechanisms. The IL-10-1082_G allele is known to correlate with altered IL-10 levels. Therefore, it might be associated with altered or abnormal inflammatory response, a mechanism that could be postulated to be important in both chronic bronchitis and coronary heart disease.

Budesonide/formoterol maintenance and reliever therapy: an effective asthma treatment option?

This 12-month dose-titration study assessed the effectiveness of budesonide/formoterol for maintenance plus relief with a control group using salmeterol/fluticasone for maintenance plus salbutamol for relief. Adolescents and adults (n = 2,143; mean forced expiratory volume in one second (FEV1) 73% predicted; mean inhaled corticosteroid (ICS) 884 microg.day(-1)) were randomised to budesonide/formoterol 160/4.5 microg two inhalations b.i.d. plus additional inhalations as needed, or salmeterol/fluticasone 50/250 microg b.i.d. plus salbutamol as needed. Treatment was prescribed open label; after 4 weeks, physicians could titrate maintenance doses in accordance with normal clinical practice. Maintenance plus as-needed budesonide/formoterol prolonged the time to first severe exacerbation versus salmeterol/fluticasone (25% risk reduction). The total number of severe exacerbations was significantly reduced in the budesonide/formoterol group (255 versus 329). Both regimens provided sustained improvements in symptoms, as-needed use, quality of life and FEV1, with differences in favour of the budesonide/formoterol group for as-needed use (0.58 versus 0.93 inhalations.day(-1)) and FEV1 (post-beta2-agonist values). Mean ICS dose during treatment was similar in both groups (653 microg budesonide.day(-1) (maintenance plus as-needed) versus 583 microg fluticasone.day(-1)). The simplified strategy using budesonide/formoterol for maintenance and reliever therapy is feasible, safe and at least as effective as salmeterol/fluticasone plus salbutamol.

Exacerbations of COPD: quantifying the patient's perspective using discrete choice modelling.

Patient-centred care is the current vogue in chronic obstructive pulmonary disease (COPD), but it is only recently that robust techniques have become available to determine patients' values and preferences. In this international cross-sectional study, patients' concerns and expectations regarding COPD exacerbations were explored using discrete choice modelling. A fractional factorial design was used to develop scenarios comprising a combination of levels for nine different attributes. In face-to-face interviews, patients were presented with paired scenarios and asked to choose the least preferable. Multinomial logit (with hierarchical Bayes) methods were used to estimate utilities. A total of 125 patients (82 males; mean age 66 yrs; 4.6 mean exacerbations.yr-1) were recruited. The attributes of exacerbations considered most important were impact on everyday life (20%), need for medical care (16%), number of future attacks (12%) and breathlessness (11%). The next most important attributes were speed of recovery, productive cough and social impact (all 9%), followed by sleep disturbance and impact on mood (both 7%). Importantly, analysis of utility shifts showed that patients most feared being hospitalised, housebound or bedridden. These issues were more important than symptom improvement. Strategies for the clinical management of chronic obstructive pulmonary disease should clearly address patients' concerns and focus on preventing and treating exacerbations to avoid these feared outcomes.
