Background Neutrophils have been implicated in the pathogenesis of COPD. Several chemoattractants for neutrophils have been measured in exhaled breath condensate (EBC) and induced-sputum (IS) from patients with COPD. Objectives The aims of this study were to compare EBC and IS supernatant neutrophil chemotactic activity from ex-smoking COPD and healthy ex-smokers, and to assess the contribution of LTB(4) to this activity. Methods 34 COPD were compared to 24 controls. EBC and IS chemotactic activity for neutrophils were assessed by using Boyden microchambers. Chemotactic index (CI) was used to evaluate cell migration. LTB(4) was measured by a specific enzyme immunoassay. Contribution of LTB4 to EBC and sputum neutrophil chemotaxis was assessed by an LTB(4) receptor antagonist (U-75302: Cayman Chemical Company, Ann Arbor, MI, USA). Results EBC and IS from both COPD and healthy subjects displayed significant neutrophil chemotactic activity but this activity was raised in COPD compared to healthy subjects. Chemotactic activity contained in sputum, however, failed to correlate with that in EBC. In COPD there was a significant correlation between EBC neutrophil chemotactic activity and sputum neutrophil counts. LTB(4) levels were raised in EBC, but not in sputum, from COPD as compared to healthy subjects. LTB(4) receptor antagonist (2.5 10(-4) M) reduced by 44.6% and by 44.4% chemotactic activity contained in EBC and sputum respectively. Conclusions EBC and IS from COPD patients have a raised neutrophil chemotactic activity to which LTB4 contributes. [less ▲]

We report the case of a 57-year-old patient in whom we found a pulmonary infection due to Mycobacterium malmoense. This patient had no immunodeficiency and responded quite rapidly to anti-tuberculous therapy. He was treated for 6 months by levofloxacine, myambutol, and nicotibine, followed by 3 months of clarithromycine, levofloxacine and myambutol. The patient improved clinically to become asymptomatic and the cavitary lesion shown at the CT-scan slightly decreased. The patient is still currently treated by clarithromycine and ciproxine.

Asthma is a frequent chronic inflammatory disease which is often mistaken for simple bronchitis. The diagnosis is based on the association of symptoms and excessive airway calibre variability. When symptoms are present more than once a week, it is recommended to give low dose inhaled corticoids as a maintenance treatment together with, as needed, rapid acting beta2 agonist. In addition it is crucial to provide the patient with an education on the disease to reinforce adherence to the treatment. [less ▲]

Budesonide/formoterol maintenance and reliever therapy (Symbicort SMART) reduces asthma exacerbations and symptoms versus fixed-dose regimens plus short-acting beta(2)-agonists (SABA) in double-blind trials. Information is lacking regarding its effectiveness versus conventional best practice (CBP). This pooled analysis of six 6-month, randomized, open-label studies examined asthma control and exacerbation risk in asthmatics (aged> or =12 years). Patients (N=7855) symptomatic on inhaled corticosteroids (ICS) or stable/symptomatic on ICS/long-acting beta(2)-agonists (LABA) received budesonide/formoterol maintenance and reliever therapy (160/4.5microg bid and as needed) or CBP (ICS or ICS/LABA+/-other agents at an approved dose plus as-needed SABA). Overall asthma control was assessed comparing the incidence of exacerbations and levels of asthma control using the asthma control questionnaire (ACQ). Budesonide/formoterol maintenance and reliever therapy did not significantly reduce time to first severe exacerbation (primary variable) versus CBP (P=0.062). However, patients in this group experienced 15% fewer exacerbations (0.20 versus 0.24/patient/year; P=0.021) and used 27% less ICS (P<0.0001). Odds of remaining well controlled (ACQ< or =0.75) over 6 months were higher with budesonide/formoterol maintenance and reliever therapy versus CBP (45% versus 41%, odds ratio [OR] 1.29; P<0.01) while risk of remaining uncontrolled decreased (25% versus 29%, OR 0.81; P<0.01). Budesonide/formoterol maintenance and reliever therapy improves key aspects of asthma control versus physicians' choice of CBP. [less ▲]

We compared the systemic and clinical effects of ciclesonide (CIC) and fluticasone propionate (FP) administered, in addition to CIC 160 microg x day(-1) and salmeterol 50 microg twice daily, in 32 patients with persistent asthma using a randomised double-blind, placebo-controlled, double-dummy, five-period crossover design. All patients exhibited a provocative concentration leading to a 20% decrease in forced expiratory volume in 1 s (PC(20)) methacholine <8 mg x mL(-1) and a PC(20) adenosine <60 mg x mL(-1). Primary outcome was 24-h serum cortisol suppression after 7 days. Secondary outcomes were changes in PC(20) methacholine and adenosine after 9 days. FP 500 microg x day(-1) and 1,000 microg x day(-1) significantly suppressed cortisol secretion versus placebo by -46.2 (95% confidence interval (CI) -83.8- -8.5) nmol x L(-1) and by -76.1 (95% CI -112.9- -39.3) nmol x L(-1), respectively. Neither dose of CIC (320 nor 640 microg x day(-1)) had a significant suppressive effect (-28.2 (95% CI -65.5-9.2) nmol x L(-1) and -37.3 (95% CI -74.7-0.0) nmol x L(-1), respectively). Differences between FP 1,000 microg x day(-1) and both CIC treatments were statistically significant (CIC 320 microg x day(-1): -48.0 (95% CI -84.8- -11.1) nmol x L(-1); CIC 640 microg x day(-1): -38.8 (95% CI -75.7- -1.9) nmol x L(-1)). Compared with placebo, the increase in PC(20) adenosine after the four treatments was small, but significant. Greater improvements in PC(20) adenosine were seen with FP 500 microg x day(-1) (1.8 (95% CI 1.0-2.6) doubling concentrations) compared with CIC 320 microg x day(-1) (0.9 (95% CI 0.1-1.7) doubling concentrations). No significant difference was seen between CIC 640 microg x day(-1) and FP 1,000 microg x day(-1). For a similar decrease in hyperresponsiveness, cortisol secretion was suppressed significantly with moderate-to-high doses of fluticasone propionate, but not with ciclesonide. [less ▲]

OBJECTIVE: To evaluate the 16- and 52-week effectiveness of add-on omalizumab treatment under real-life heterogeneity in patients, settings, and physicians in an open-label, multicenter, pharmaco-epidemiologic study of patients with severe persistent allergic asthma in Belgium. METHODS: Effectiveness outcomes included improvement in 2005 global initiative for asthma (GINA) classification, physician-rated global evaluation of treatment effectiveness (GETE), quality of life (Juniper asthma-related quality of life (AQLQ) and European quality of life questionnaire 5 dimensions (EQ-5D)), and severe asthma exacerbations. Patients studied included both intent-to-treat and per-protocol populations. RESULTS: The sample (n=158) had a mean age of 48.17+/-17.18 years, and a slight majority were female (53.8%). Despite being treated with high-dose inhaled corticosteroids and long-acting beta2-agonists, all patients experienced frequent symptoms and had exacerbations in the past year. At 16 weeks, >82% had good/excellent GETE (P values <0.001), >82% had an improvement in total AQLQ scores of > or =0.5 points (P<0.001), and >91% were severe exacerbation-free (P<0.001). At 52 weeks, >72% had a good/excellent GETE rating (P<0.001), >84% had improvements in total AQLQ score of > or =0.5 points (P<0.001), >56% had minimally important improvements in EQ-5D utility scores (P=0.012), and >65% were severe exacerbation-free (P<0.001). Significant reductions in healthcare utilization compared to the one year prior to treatment were noted. CONCLUSION: The PERSIST study shows better physician-rated effectiveness, greater improvements in quality of life, greater reductions in exacerbation rates, and greater reductions in healthcare utilization than previously reported in efficacy studies. Under real-life conditions, omalizumab is effective as add-on therapy in the treatment of patients with persistent severe allergic asthma. [less ▲]

Exhaled nitric oxide fraction (F(eNO)), which is a reliable marker of eosinophilic airway inflammation, is partially suppressed by tobacco smoking. Consequently, its potential as a biomarker in asthma management has never been evaluated in smoking patients. In the present study, the authors tested the validity of F(eNO) to predict asthma control in this population. F(eNO) and the Asthma Control Questionnaire (ACQ) were recorded at least once in 411 nonsmoking (345 with at least two visits) and 59 smoking (51 with at least two visits) asthma patients. Despite similar mean ACQ scores (1.5 versus 1.7), F(eNO) was reduced in smoking asthmatics (18.1 ppb versus 33.7 ppb). A decrease in F(eNO) of <20% precludes asthma control improvement in nonsmoking (negative predictive value (NPV) 78%) and in smoking patients (NPV 72%). An increase in F(eNO) <30% is unlikely to be associated with deterioration in asthma control in both groups of patients (NPV = 86% and 84% in nonsmoking and smoking patients, respectively). It is concluded that, even in smokers, sequential changes in F(eNO) have a relationship with asthma control. The present study is the first to indicate that cigarette smoking does not obviate the clinical value of measuring F(eNO) in asthma among smokers. [less ▲]

Inflammation and remodelling are constant features of asthma. They are present throughout the whole bronchial tree, even in the small airways (less than 2 mm). The inflammatory cell infiltrate and structural changes are, in most cases, identical. However, in severe asthma, nocturnal asthma and fatal asthma, the cellular infiltrate in the distal airways is more intense and the number of activated cells is increased. In fatal asthma there are major alterations in the distal airways involving the smooth muscle and the bronchial epithelium, and mucus hypersecretion leading to distal airway plugging. Thus the histopathological changes in the distal airways contribute to the most severe stages of asthma and should be targeted by treatment. Currently the non-invasive tools that reflect inflammation are unable to assess these changes in the distal airways. [less ▲]

The UPLIFT study (Understanding Potential Long-term Impacts on Function with Tiotropium) was a double-blind, randomised, international, multicentric, placebo-controlled clinical trial, investigating with tiotropium (Spiriva) the change in the annual rate of decline in FEV1 in chronic obstructive pulmonary disease (COPD). Secondary end points included COPD exacerbation rate with or without hospitalisation, lung function, quality of life and mortality. 5.993 patients were randomized. In this article, we briefly describe the most important results of the study. While tiotropium did not alter the annual rate of decline in FEV1 (pre and postbronchodilatation), it improved lung function and quality of life, and reduced exacerbations and hospitalisations by comparison with control for up to 4 years. Tiotropium also reduced respiratory and cardiac morbidity. [less ▲]

Objective Animal models of asthma mimic major features of human disease. Since the genetic background of experimental animals might affect hyperresponsiveness and inflammation, we studied its potential influence and the mechanisms leading to differences in strains. Methods We applied a mouse model of allergic asthma to BALB/c and C57BL/6 mice. Results BALB/c mice displayed greater levels of airway reactivity to methacholine than C57BL/6 mice. Moreover, BALB/c mice exhibited higher numbers of mast cells in lung tissue when compared to C57BL/6. On the contrary, eosinophil and neutrophil counts in bronchoalveolar lavage fluid (BALF) as well as peribronchial eosinophilia were greater in C57BL/6. IL (Interleukin)-4, IL-5, IL-13, and CCL11 levels measured in whole-lung extracts were higher in BALB/c, while, in sharp contrast, CCL11 and CCL5 levels were higher in BALF of C57BL/6 mice. Conclusions We observed phenotypic differences between C57BL/6 and BALB/c mice in an asthma model with different distributions of pro-inflammatory cytokines and inflammatory cells. [less ▲]

OBJECTIVE: To study the effectiveness and safety of budesonide/formoterol (Symbicort) Maintenance And Reliever Therapy (Symbicort SMART, AstraZeneca, Sodertalje, Sweden), a simplified management approach with one inhaler compared with conventional best practice (CBP) with multiple inhalers in patients with persistent asthma. DESIGN: Open-label randomised controlled parallel group trial, 6-month treatment. PARTICIPANTS: A total of 908 patients > or = 12 years of age, with persistent asthma receiving treatment with inhaled corticosteroids (ICS), either alone or in conjunction with long-acting beta(2)-agonist. MAIN OUTCOME MEASURES: Time to first severe asthma exacerbation and number of severe asthma exacerbations. RESULTS: No difference between groups was seen in time to first severe exacerbation (p = 0.75). Exacerbation rates were low in both groups. A total of 12 patients in the Symbicort SMART group experienced a total of 14 severe asthma exacerbations, and 19 patients in the CBP group experienced a total of 25 severe asthma exacerbations (annual rate 0.07 vs. 0.13 p = 0.09). The mean daily dose of ICS expressed in BDP equivalent was significantly lower in the Symbicort SMART group (including as-needed use) vs. in the CBP group (749 microg vs. 1059 microg; p < 0.0001). Mean scores in Asthma Control Questionnaire, 5 question version improved significantly in the SMART group compared with the CBP group (p = 0.0026). Symbicort SMART and CBP were equally well tolerated. The mean drug cost/patient/month was significantly lower for the patients in the Symbicort SMART group compared with patients receiving CBP (51.3 euros vs. 66.5 euros; p < 0.0001). CONCLUSIONS: In Belgian patients, a simplified regimen using budesonide/formoterol maintenance and reliever therapy was at least as effective at improving clinical control compared with CBP with a significantly lower ICS dose and significantly lower drug costs.

Induction of sputum by inhalation of hypertonic or isotonic fluid makes possible the safe and noninvasive harvesting of airway cells from patients with asthma, regardless of disease severity. Analysis of sputum cells has helped to identify different phenotypes of refractory asthma and shown that such asthma can be eosinophilic, neutrophilic, or both. Elevated eosinophil levels in sputum indicate a risk of exacerbation if the corticosteroid dose is reduced in stabilized patients. Surveillance of eosinophilia levels as an indicator for corticosteroid adjustment in refractory asthma makes it possible to reduce the frequency of severe exacerbations. [less ▲]

INTRODUCTION: Positron emission tomography (PET) has a clear role in oncology, particularly in thoracic disease. In the light of our experience and a revue of the literature we define precisely the role of metabolic imaging in the diagnosis of pleural pathology. BACKGROUND: In particular PET allows characterisation of malignant pleural disease and provides prognostic information in mesothelioma. Metabolic imaging provides clinical information for the staging of pulmonary cancer, in the search for a primary tumour in metastatic pleurisy and also in the follow up of chronic or recurrent pleural pathology. CONCLUSIONS: It is justified, therefore, that PET joins the diagnostic armamentarium of pleural pathology, solid or liquid. [less ▲]

Pleural involvements are common and various respiratory diseases including inflammatory, infectious, occupational, or neoplastic pathological entities...Pleural thickening and pleurisy are usual radiological presentation. Etiological diagnosis imposes a vast and sometimes difficult exploration and it, especially since the conventional imaging by radiology, ultrasound, scanning and nuclear magnetic resonance has no specific diagnostic criteria for pleural malignancy. The metabolic imaging by positron emission tomography (PET) has been gradually positioned in the decision-making algorithm exploration of the pleural disease due to its excellent sensitivity in the diagnosis of malignant pleurisy (88.8%-100%). The analysis of chemistry, bacteriology and cytology pleural fluid makes a significant contribution to the diagnostic approach. However, although inescapable, thoracocentesis has a diagnostic sensibility not exceeding 62%. Moreover, the sensibility of the pleural blind needle biopsies does not exceed 51%. So, thoracoscopy, more invasive, is often justified to precise pleural disease with a diagnostic sensitivity greater than 95%. Finally, despite the diagnostic arsenal available, over 10% of pleurisies remain unknown etiology. [less ▲]
