Introduction.— La force et l’endurance respiratoires seraient susceptibles d’influencer certaines performances sportives. Outre la spirométrie classique, les pressions inspiratoires et expiratoires maximales ainsi que le reniflement maximal apprécient la force respiratoire. La musculature respiratoire pourrait être améliorée par l’utilisation régulière d’appareils avec résistance inspiratoire ou expiratoire. Méthodes.— Dix-neuf sujets, âgés de 18 à 30 ans, pratiquant un sport de loisir ont bénéficié d’un entraînement de huit semaines sur Powerbreathe® (60 inspirations par jour), la résistance étant fixée à 85 % de la pression inspiratoire maximale déterminée lors d’une évaluation préalable. Résultats.— Une augmentation de 21,77 % de la pression inspiratoire maximale, de 17 % de la pression expiratoire maximale et de 18 % du test de reniflement ont été constatées après huit semaines d’entraînement. Conclusions.— Un entraînement spécifique de la musculature inspiratoire augmente effectivement la puissance de ces muscles (manoeuvres volontaires et non-invasives - Macro 5000® - mesure des pressions respiratoires et du sniff test).

INTRODUCTION: The objective of the present article is to review available data on possible links between phenotypes and inflammatory profiles in patients with chronic obstructive pulmonary disease (COPD). BACKGROUND: Chronic bronchitis is associated with proximal bronchial inflammation and small airway inflammation with remodeling at the site of obstruction. CT scanning enables patients to be phenotyped according to the predominantly bronchial or emphysematous nature of the morphological abnormality. Exacerbations, in a context of persistently elevated baseline inflammation, are associated with increased inflammation and a poor prognosis. Long-term studies have correlated inflammatory markers (and anti-inflammatory drug effects) with dynamic hyperinflation, possibly confirming that inflammation promotes hyperinflation. The inflammatory cell count in the pulmonary arterial walls correlates with the severity of endothelial dysfunction. The risk of developing pulmonary hypertension would seem to increase with low-grade systemic inflammation. The role of low-grade systemic inflammation in COPD co-morbidities, and in nutritional and muscular involvement in particular, remains a matter of debate. Regular physical exercise may help reduce this inflammation. CONCLUSIONS: In COPD, many aspects of the clinical phenotype are related to inflammation. Better knowledge of these relationships could help optimize current and future treatments. [less ▲]

INTRODUCTION: Management of chronic obstructive pulmonary disease (COPD) has made considerable progress over the last 15 years, with the development of pulmonary rehabilitation, new molecules to facilitate smoking cessation, and several medical treatments. Many therapeutic needs, however, remain to be met. STATE OF THE ART: Several lines of research on inflammation and COPD are promising, and some will probably result in new treatments. These may target specific populations, identified by clinical phenotype or by biomarkers. The forthcoming arrival of iPDE-4s on the market illustrates how knowledge of inflammation and remodeling and of some of the underlying mechanisms finally, after many years' development, has broadened the range of treatments available to help improve patients' daily life and outcomes. PERSPECTIVES AND CONCLUSIONS: The availability of such treatments, however, does not mean that knowledge of the disease in the general population and among healthcare workers can be neglected. Early detection (at a stage when treatment can already be effective) and patient education which promotes therapeutic compliance and lasting lifestyle change need to be developed further. [less ▲]

INTRODUCTION: Positron emission tomography (PET) now plays a clear role in oncology, especially in chest tumours. We discuss the value of metabolic imaging in characterising pleural pathology in the light of our own experience and review the literature. BACKGROUND: PET is particularly useful in characterising malignant pleural pathologies and is a factor of prognosis in mesothelioma. Metabolic imaging also provides clinical information for staging lung cancer, in researching the primary tumour in metastatic pleurisy and in monitoring chronic or recurrent pleural pathologies. CONCLUSIONS: PET should therefore be considered as a useful tool in the diagnosis of liquid or solid pleural pathologies. [less ▲]

The present study reviews the literature on inflammation and remodelling mechanisms in chronic obstructive pulmonary disease (COPD). The development of COPD is associated with chronic pulmonary inflammation. Immunity (innate or adaptive) plays a role in its onset and continuation. Airways inflammation alters bronchial structure/function relations: increased bronchial wall thickness, increased bronchial smooth muscle tone, seromucosal gland hypersecretion and loss of elastic structures. Circulating markers of pulmonary inflammation indicate its systemic dissemination. Oxidative stress plays a major role in the onset and persistence of tissue abnormalities. The determinants of extra- and intra-cellular redox control are only partially known. Susceptibility genes, antioxidant system insufficiency and reduced levels of anti-age molecules and of histone deacetylation are also involved. The molecular and cellular targets of inflammation and remodelling are numerous and complex. Currently, tools exist to limit inflammation in COPD but not to act on structural remodelling. [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 ▲]

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 ▲]

INTRODUCTION: The technique of induced expectoration generates sputum by the inhalation of hypertonic saline. On account of its non-invasive character, its simplicity, its relative harmlessness, its cost effectiveness and its reproducibility this technique, that appeared in the early 1990's, has rapidly established itself as the technique of choice in the investigation of bronchial inflammation in asthma. STATE OF THE ART: We present the results of our studies that have contributed to the validation of the technique at the methodological level and to the exploitation of the cellular contents as much as the fluid phase of the expectorations in characterising bronchial inflammation in asthmatics. Our results confirm an infiltration of the airways of asthmatics with eosinophils that appears to be proportional to the severity of the illness. We evaluate the effect of inhaled steroids and of theophylline on sputum eosinophilia and bronchial reactivity and discuss the role of eosinophils on bronchial hyperreactivity. Finally we discuss the use of induced expectoration in clinical practice in asthma. PERSPECTIVES: The analysis of induced sputum could well become a valuable tool in the clinical evaluation and monitoring of asthma in the same way as symptoms and abnormalities of lung function. CONCLUSIONS: Induced expectoration has certainly contributed to the understanding of the cellular and molecular mechanisms of asthma as well as the role of bronchial inflammation in the clinical manifestations of the disease.

PositIon emission tomography using 18-fluorodeoxyglucose (FDG-PET) is an imaging technique based on metabolic criteria rather than morphological criteria. We discuss the contribution of this technique in the field of pulmonary oncology and we summarize our work which has demonstrated the performance capacity of PET: to discriminate the malignant nature of a solitary pulmonary nodule; to improve sensitivity over CT for mediastinal assessment in non-small cell lung cancer; to seRach for distant metastasis in patients with non-small cell lung cancer; to complement CT imaging to better dissociate tumor residue or recurrence from post-therapeutic sequelae in non-small cell lung cancer. Finally, we present different expected progress for the future. [less ▲]

The data of the literature concerning bronchial reactivity in diabetic patients are controversial. Therefore, we studied the influence of the presence of a diabetic cardiac autonomic neuropathy (CAN) on the ventilatory parameters measured during a methacholine-induced bronchoconstriction test. Ten insulin-dependent diabetic patients without CAN, ten insulin-dependent diabetic patients with CAN and ten healthy volunteers, all non-smokers and free of respiratory symptoms, have undergone a functional respiratory check-up before the methacholine test. The presence of CAN was classically studied by the decrease in heart rate changes during three standardized tests (deep breathing at 6 cycles/min, Valsalva manoeuver, orthostatism) which all mainly explore the parasympathetic function. The bronchial response to methacholine was similar in the healthy subjects and in the diabetic patients without CAN. However, the fall in forced expiratory volume in 1 second induced by the highest dose of methacholine was significantly less marked in the diabetic subjects with CAN than in the two other groups. These results suggest that the diabetic autonomic neuropathy also involves the vagal innervation of the respiratory tract. [less ▲]

Current methods for evaluating the mediastinum include chest radiography, computed tomography (CT) or magnetic resonance (MR) imaging and mediastinoscopy. Despite advances in morphologic imaging, some lung cancer patients are found to have unresectable disease at surgery. In contrast to CT scan or MR imaging, which depend primarily on anatomic and morphological criteria, positron emission tomography (PET) with 18fluorodeoxyglucose (FDG) depends mainly of the metabolic characteristics of a tissue for the diagnosis of disease. We perform a prospective study to compare FDG-PET and CT of the thorax in the presurgical assessment of the mediastinum in patients with newly diagnosed non-small cell lung cancer. Thirty patients have been included. CT and PET-scans were interpreted separately and results were compared to surgical staging during thoracotomy. In assessing mediastinal involvement, CT scan had a sensitivity of 56% and a specificity of 64%. For diagnosis mediastinal nodal disease, FDG-PET was 87% sensitive and 78% specific. Its positive predictive value was 82%, and the negative value was 83%. In conclusion, our preliminary results show that FDG-PET appears more accurate than CT in staging of mediastinal non-small cell lung cancer. [less ▲]

The pathogenesis of bronchospasm of effort is not yet elucidated and it is probable that is determined by multiple factors. In this study we have tested the role of mastocytes in taking as an index of their activation the fluctuation of plasma histamine levels during repeated exercise tests. We will show that asthmatic subjects who develop bronchospasm on effort have a significant rise (times 3) in their level of serum histamine whilst normal subjects don't show much change. Furthermore in a repeated effort test we have observed a strict parallelism between the occurrence of bronchospasm of effort and a rise in plasma histamine levels. These different observations enable us to consider that the activation of mastocytes and the liberation of mediators which follow play an important role in the pathogenesis of bronchospasm of effort.

The aim of this study was to specify the effect of therapeutic pulmonary lavage on the function of alveolar macrophages in a patient suffering from alveolar proteinosis; we have studied phagocytosis and chemotaxis in cells before and at different times after the lavage. Our results indicate a restoration of the functional properties of the alveolar macrophages in parallel with an improvement in pulmonary function and blood gases under the effects of treatment. These data are in favour with an inhibitory effect of the lipoprotein material on the function of alveolar macrophages and suggest that the deposit of this material is a determining factor in the alteration in the defense mechanisms of the lung.
