Abstract
In the management of cystic fibrosis, treatments against Staphylococcus aureus and Haemophilus influenzae such as amoxicillin or cotrimoxazole have to be prescribed and the antibiotherapy's efficacy may be linked to the concentration that reaches the infected site. As cystic fibrosis patients present disturbed pharmacokinetics parameters, drug monitoring would be relevant to assess the lung distribution of antibiotics and to optimize dosing regimens. In this context, the aim of the study was to develop and validate HPLC-based methods for the determination of both antibiotics in bronchial sputum from cystic fibrosis patients, in order to assess the distribution of the drugs into the lungs. Plasma proteins were precipitated by acetonitrile and amoxicillin concentrations in sputum were determined by HPLC coupled with tandem-mass spectrometry. Following liquid extraction with ethyl acetate, cotrimoxazole was quantified by HPLC using ultraviolet detection. Both methods were rapid, specific, accurate and reproducible. The method was applied to patient samples. In three treated patients, concentrations of amoxicillin in sputum were similar and below the lower limit of quantification (0.1 μg/g) and in six patients, sputum concentrations up to 11.1 and 6.4 μg/g were measured for sulfamethoxazole and trimethoprim, respectively.

Abstract
INTRODUCTION Lung volume reduction can be effective in appropriately selected patients with severe emphysema and is associated with reduced breathlessness and improved survival. Spontaneous resolution of emphysematous bullae can also sometimes occur. CASE REPORT We report a case of severe smoking-related emphysema in a 60-year-old patient, who presented in October 2013 with a right upper lobe acute community-acquired pneumonia on the background of previously undocumented emphysema. The patient improved following treatment with co-amoxiclav and serial radiology showed progressive cicatricial retraction. Nine months later there had been a major functional improvement characterized by a complete normalization of the patient's ventilatory parameters, specifically a 45% improvement in FEV1. In the literature, the average FEV1 improvement obtained by surgical or endoscopic lung volume reduction techniques does not exceed 28%. CONCLUSION Rarely, emphysematous bullae resolve following infections. Further studies of the mechanisms involved in these natural regressions may be of interest in the development of new therapeutics.

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) is a common but under-diagnosed pathology in primary care. The objective was to study the feasibility of a randomized controlled trial in general practice to detect new cases of COPD at an earlier stage. METHODS A cluster randomized, controlled, multicenter intervention study comparing, according to a 2×2 factorial plan, two case finding strategies: a systematic GOLD-HAS hetero-questionnaire and coordination of the patient's path to facilitate access to spirometry. The PIL-DISCO pilot study took place in 2017. Patients between 40 and 80 years old, with no previous history of COPD, consulting their GP on a given day regardless of the reason, were included. RESULTS 176 patients were included in 1.5 days. Spirometry was performed in none of the control arm, in 13 (29.5%) of the questionnaire arm, in 22 (50%) in the coordination arm and in 32 (72.7%) with the combination of the two strategies. Two cases of stage 2 COPD and thirteen other respiratory diseases were diagnosed. CONCLUSIONS This study confirms the feasibility of the protocol in primary care in terms of speed of inclusion and acceptability. An extension phase aiming to include 3200 patients will assess the diagnostic value of the two strategies tested in general practice.

Abstract
Background and Aims A risk of tracheal mucosa injury induced by subglottic suctioning has been raised. Therefore, this prospective randomized study aims to compare the effect of continuous suctioning of subglottic secretions versus intermittent suctioning of subglottic secretions (CSSS vs. ISSS) secretions on tracheal mucosa in front of the suctioning port of the endotracheal tube. Patients and Methods Patients requiring intubation or reintubation in Intensive Care Unit with an expected ventilation duration > 24 h were eligible. Participants received CSSS at -20 mmHg or ISSS at -100 mmHg during 15 s and no suction during 8 s. The effect on tracheal mucosa in front of the suction port was assessed after intubation (T0) and before extubation (T1) using bronchoscopy. Tracheal mucosa damages were graded into five categories (no injury, erythema, edema, ulceration, or necrosis). The occurrence (no injury observed at T0 but present at T1) or the worsening (injury observed at T0 exacerbating at T1) was studied. Results Seventy-three patients were included and 53 patients (CSSS, n = 26 and ISSS, n = 27) were evaluable on the primary endpoint. The occurrence or worsening of tracheal mucosal damages did not differ between the two groups (CSSS, n = 7 [27%] vs. ISSS, n = 5 [17%], P = 0.465). Daily average volume of suctioned secretion was higher with ISSS (74 ± 100 ml vs. 20 ± 25 ml, P < 0.001). Impossibility to aspirate was higher with CSSS (0.14 ± 0.16 per day vs. 0.03 ± 0.07 per day, P < 0.001). Conclusions Our results suggest that tracheal mucosal damages did not differ between CSSS and ISSS. The aspirated volume was higher and impossibility to aspirate was lower with ISSS.

Abstract
General practitioners (GP) are in a special position to conduct educational strategies for their patients with chronic disease. Despite the GP’s desire to be involved in patient education, this approach remains underdeveloped.Objective: To determine the factors required support the development of educational strategies in general practice from the GPs’ perspective.Methods: Qualitative study based on a “modified nominal group technique” carried out among 21 GPs (not specifically trained in patient education) participating as investigators in an interventional study testing a structured educational strategy. The interventional study based on processes and tools specifically developed to suit general practice was held during their usual consultations. Thirty one patients with COPD were followed for 9 months.Results: GPs identified 23 specific factors restructured after the clarification-reformulation step in 6 main factors required for the development of educational strategies in general practice. The consensus revealed that reinforcement of initial and continuing medical training was the most frequently cited factor and was considered to be a priority. The development of inter- and intra-professional cooperation was the second leading factor to be taken into account.Conclusion: The improvement of GP training and the promotion of areas of cooperation could help GPs to develop educational strategies during their consultations. These results may provide insight to regional health agencies concerning the deployment of patient education in primary care.

Abstract
COPD is a slowly progressive chronic respiratory disease causing an irreversible decrease in air flow. The main cause is smoking, which provokes inflammatory phenomena in the respiratory tract. COPD is a serious public health issue, causing high morbidity, mortality and disability. Related comorbidities are linked to ageing, common risk factors and genetic predispositions. A combination of comorbidities increases healthcare costs. For instance, patients with more than two comorbidities represent a quarter of all COPD sufferers but account for half the related health costs. Our review describes different comorbidities and their impact on the COPD prognosis. The comorbidities include: cardiovascular diseases, osteoporosis, denutrition, obesity, ageing, anemia, sleeping disorders, diabetes, metabolic syndrome, anxiety-depression and lung cancer. The prognosis worsens with one or more comorbidities. Clinicians are faced with the challenge of finding practical and appropriate ways of treating these comorbidities, and there is increasing interest in developing a global, multidisciplinary approach to management. Managing this chronic disease should be based on a holistic, patient-centred approach and smoking cessation remains the key factor in the care of COPD patients.

Abstract
OBJECTIVE Kawasaki disease (KD) is a vasculitis that mostly occurs in young children and rarely in adults. We analyzed the characteristics of adult-onset KD (AKD) in France. METHODS We collected retrospective and prospective data for patients with a diagnosis of KD occurring after the age of 18 years. Cases were obtained via various French medical networks and identified from the international literature. RESULTS We included 43 patients of AKD at 26 institution from 1992 to 2015, with mean (SD) age 30 (11) years (range 18-68) and sex ratio (M/F) 1.2; 34 patients met the American Heart Association criteria and 9 were incomplete AKD. The median time to diagnosis was 13 days (interquartile range 8-21). The main symptoms were fever (100%), exanthema (98%), changes in the extremities (91%), conjunctivitis (77%), oral cavity changes (89%), cervical adenitis (55%) and cardiac abnormalities (45%). Overall, 35% of patients showed large-vessel vasculitis: coronary vasculitis (26%) and coronary aneurysm (19%). Treatment was mostly intravenous immunoglobulins (79%) and aspirin (81%). Four patients showed myocardial infarction due to coronary vasculitis, but none were treated with IVIg because of late diagnosis. After a median follow-up of 5 months (range 1-117), persistent aneurysm was noted in 9% of cases. Damage was significantly lower with early treatment than late or no treatment (p=0.01). CONCLUSION Given the high frequency of cardiac involvement and complications in this series of AKD, diagnosis and treatment should not be delayed, and early IVIg treatment seems to improve the outcome.

Abstract
La Société de pneumologie de langue française définie l’exacerbation aiguë de bronchopneumopathie chronique obstructive comme une majoration des symptômes respiratoires au-delà des variations quotidiennes (en pratique, d’une durée ≥ 48 h ou justifiant une modification thérapeutique). La cause de ces exacerbations est principalement infectieuse : virale (rhinovirus, virus influenzae et parainfluenzae, coronavirus, adénovirus et virus respiratoire syncytial) ou bactérienne (principalement, Haemophilus influenzae, Streptococcus pneumoniae et Moraxella catarrhalis). Elles peuvent également résulter de l’exposition à certains polluants : NO2, SO2, ozone et pollution particulaire (PM10 et PM2,5). Elle reste indéterminée dans près de 30 % des cas. Les diagnostics différentiels incluent les pneumopathies infectieuses, les pneumothorax, les poussées d’insuffisance cardiaque et les embolies pulmonaires. La présence de signes de gravité conditionne l’hospitalisation : signes d’insuffisance respiratoire aiguë, de choc ou de défaillance neurologique, mais aussi en cas de patient fragile, d’absence de soutien familial à domicile ou de réponse au traitement initial. Le traitement consiste en une majoration des bronchodilatateurs, une kinésithérapie respiratoire, une antibiothérapie en cas d’expectoration franchement purulente. La prescription de corticoïdes systémiques ne doit pas être systématique. La dose recommandée est de 0,5 mg/kg sur une courte période (5–7 jours). Lors d’une hospitalisation, une oxygénothérapie et une thromboprophylaxie peuvent être instaurées. La ventilation non invasive est principalement indiquée en cas de persistance d’une hypercapnie malgré un traitement médical optimal. Que le patient soit pris en charge en ambulatoire ou en hospitalisation, une réévaluation clinique à 48–72 h est indispensable.

Abstract
The Société de pneumologie de langue française defines acute exacerbation of chronic obstructive pulmonary disease (AE COPD) as an increase in daily respiratory symptoms, basically duration ≥ 48h or need for treatment adjustment. Etiology of EA COPD are mainly infectious, viral (rhinovirus, influenzae or parainfluenzae virus, coronavirus, adenovirus and respiratory syncytial virus) or bacterial (Haemophilus influenzae, Streptococcus pneumoniae, or Moraxella catarrhalis). Pollutant exposure can also lead to AE COPD, such as NO2, SO2, ozone or particulates (PM10 and PM2.5). In 30% the etiology remains unknown. Differential diagnoses of AE COPD include infectious pneumonia, pneumothorax, acute heart failure and pulmonary embolism. Presences of signs of severity impose hospitalization: signs of respiratory distress, shock, acute confusion but also fragile patients, insufficient home support or absence of response to initial treatment. AE COPD treatments consist on increase in bronchodilators, chest physiotherapy, and antibiotics if sputum is frankly purulent. Systemic corticosteroids should not be systematic. Recommended dose is 0.5 mg/kg on short course (5-7 days). During hospitalization, oxygen supplementation and thromboprophylaxis could be prescribed. The main interest in non-invasive ventilation is persistent hypercapnia despite optimal medical management. During ambulatory management or hospitalization, clinical assessment at 48-72 h is mandatory.

Abstract
Reports regarding gender-related differences in COPD expression have provided conflicting results. In the French Initiatives BPCO real-world cohort, which contained 688 patients (146 women) when data were extracted, women were matched with men (1:3 ratio: n = 107:275) on age (5-year intervals) and FEV1 (5% predicted intervals) and comparisons were performed using univariate logistic regressions. For a given age and level of airflow obstruction, women with COPD had higher BOD scores due to more pronounced dyspnea and lower BMI, suggesting worse prognosis, and were more likely to exhibit anxiety, suggesting the need for specific assessment and care.

Abstract
BACKGROUND Early in life, cystic fibrosis (CF) patients are infected with microorganisms. The role of macrophages has largely been underestimated in literature, whereas the focus being mostly on neutrophils and epithelial cells. Macrophages may however play a significant role in the initiating stages of this disease, via an inability to act as a suppressor cell. Yet macrophage dysfunction may be the first step in cascade of events leading to chronic inflammation/infection in CF. Moreover, reports have suggested that CFTR contribute to altered inflammatory response in CF by modification of normal macrophage functions. OBJECTIVES In order to highlight possible intrinsic macrophage defects due to impaired CFTR, we have studied inflammatory cytokines secretions, recognition of pathogens and phagocytosis in peripheral blood monocyte-derived macrophages from stable adult CF patients and healthy subjects (non-CF). RESULTS In CF macrophage supernatants, concentrations of sCD14, IL-1β, IL-6, TNF-α and IL-10 were strongly raised. Furthermore expression of CD11b and TLR-5 were sorely decreased on CF macrophages. Beside, no difference was observed for mCD14, CD16, CD64, TLR-4 and TLR1/TLR-2 expressions. Moreover, a strong inhibition of phagocytosis was observed for CF macrophages. Elsewhere CFTR inhibition in non-CF macrophages also led to alterations of phagocytosis function as well as CD11b expression. CONCLUSIONS Altogether, these findings demonstrate excessive inflammation in CF macrophages, characterized by overproduction of sCD14 and inflammatory cytokines, with decreased expression of CD11b and TLR-5, and impaired phagocytosis. This leads to altered clearance of pathogens and non-resolution of infection by CF macrophages, thereby inducing an exaggerated pro-inflammatory response.

Abstract
Background The contribution of occupational exposures to COPD and their interaction with cigarette smoking on clinical pattern of COPD remain underappreciated. The aim of this study was to explore the contribution of occupational exposures on clinical pattern of COPD. Methods Cross-sectional data from a multicenter tertiary care cohort of 591 smokers or ex-smokers with COPD (median FEV1 49%) were analyzed. Self-reported exposure to vapor, dust, gas or fumes (VDGF) at any time during the entire career was recorded. Results VDGF exposure was reported in 209 (35%) subjects aged 31 to 88 years. Several features were significantly associated with VDGF exposure: age (median 68 versus 64 years, p < 0.001), male gender (90% vs 76%; p < 0.0001), reported work-related respiratory disability (86% vs 7%, p < 0.001), current wheezing (71% vs 61%, p = 0.03) and hay fever (15.5% vs 8.5%, p < 0.01). In contrast, current and cumulative smoking was less (p = 0.01) despite similar severity of airflow obstruction. Conclusion In this patient series of COPD patients, subjects exposed to VDGF were older male patients who reported more work-related respiratory disability, more asthma-like symptoms and atopy, suggesting that, even in smokers or ex-smokers with COPD, occupational exposures are associated with distinct patients characteristics.

Abstract
BACKGROUND Early in life, patients with cystic fibrosis (CF) are infected with microorganisms including bacteria and fungi, particularly Pseudomonas aeruginosa and Aspergillus fumigatus. Since recent research has identified the anti-inflammatory properties of statins (besides their lipid-lowering effects), we investigated the effect of fluvastatin on the production of the potent neutrophil chemoattractant chemokine, IL-8, in whole blood from CF patients, stimulated by Pseudomonas aeruginosa (LPS) and Aspergillus fumigatus (AFA) antigens. RESULTS Whole blood from adult patients with CF and from healthy volunteers was collected at the Rennes University Hospital (France). Blood was pretreated for 1 h with fluvastatin (0-300 µM) and incubated for 24 h with LPS (10 µg/mL) and/or AFA (diluted 1/200). IL-8 protein levels, quantified by ELISA, were increased in a concentration-dependent manner when cells were stimulated by LPS or AFA. Fluvastatin strongly decreased the levels of IL-8, in a concentration-dependent manner, in whole blood from CF patients. However, its inhibitory effect was decreased or absent in whole blood from healthy subjects. Furthermore, the inhibition induced by fluvastatin in CF whole blood was reversed in the presence of intermediates within the cholesterol biosynthesis pathway, mevalonate, farnesyl pyprophosphate or geranylgeranyl pyrophosphate that activate small GTPases by isoprenylation. CONCLUSIONS For the first time, the inhibitory effects of fluvastatin on CF systemic inflammation may reveal the important therapeutic potential of statins in pathological conditions associated with the over-production of pro-inflammatory cytokines and chemokines as observed during the manifestation of CF. The anti-inflammatory effect could be related to the modulation of the prenylation of signalling proteins.

Abstract
Extracellular matrix metalloproteinase inducer (EMMPRIN) was examined on bronchoalveolar lavage fluids (BALFs) and lung tissue from patients with fibrosis (usual interstitial pneumonia-idiopathic pulmonary fibrosis [UIP-IPF], n = 15; diffuse parenchymal lung diseases without IPF characteristics on computerized tomography scan, n = 8) and without fibrosis (n = 6). In UIP-IPF, EMMPRIN staining was increased in areas of fibrosis, mainly in macrophages and in epithelial cells. EMMPRIN was also found in the extracellular medium with significant levels in patients with lung fibrosis compared to subjects without fibrosis. Moreover, macrophages from patients with lung fibrosis spontaneously produce EMMPRIN. These findings show that EMMPRIN is increased in lung fibrosis.

Abstract
Pulmonary alveolar phospholipoproteinosis is a rare lung disease of unknown cause characterized by surfactant plugging of the alveoli. At the present time, surgical lung biopsy, long considered as the gold standard, is not necessary for positive diagnosis of pulmonary alveolar phospholipoproteinosis when computed tomography anomalies and analysis of bronchial lavage fluids present a typical pattern. Treatment requires abundant lavage, but the demonstration of anti-GM-CSF antibodies in primary forms opens new therapeutic perspectives.

Abstract
Chronic obstructive pulmonary disease (COPD) is a common, progressive respiratory disease that causes great morbidity and mortality despite treatment. Tumor necrosis factor alpha (TNF-alpha) plays a central role as a pro-inflammatory cytokine in COPD. TNF-alpha release is markedly inhibited by phosphodiesterase type 4 (PDE4) inhibitors that have proven efficacious in COPD clinical trials. The aim of this study was to compare the in vitro activities of the novel selective PDE4 inhibitors CI-1044 compared to well-known PDE4 inhibitors, rolipram and cilomilast, and to the glucocorticoid dexamethasone at reducing lipopolysaccharide (LPS)-induced TNF-alpha release in whole blood from COPD patients and healthy subjects. In the whole blood from COPD patients pre-incubation with PDE4 inhibitors or dexamethasone resulted in a dose-dependent inhibition of LPS-induced TNF-alpha release with IC(50) values of 1.3+/-0.7, 2.8+/-0.9 microM, higher to 10 microM and lesser than 0.03 microM for CI-1044, rolipram, cilomilast and dexamethasone, respectively. We observed a similar inhibition in the whole blood from healthy volunteers with, however, higher IC(50) values. These results indicate that CI-1044 inhibits in vitro LPS-induced TNF-alpha release in whole blood from COPD patients better than rolipram and cilomilast and suggested that it could be a useful anti-inflammatory therapy in COPD.

Abstract
INTRODUCTION Erosion of mediastinal adenopathy into the bronchial tree is classically associated with tuberculosis. We describe two cases of of such bronchial erosion with Hodgkin's disease. CASE REPORT The first case was of a seventy-year old man with a history of pulmonary silicosis. A sub-carenal mass was identified during investigation of chronic cough. The bronchoscopy revealed an inflammatory stenosis due to Hodgkin's disease. The second case was of a thirteen-year old child whose Hodgkin's disease was thought to be in remission following treatment. The erosion of mediastinal adenopathy into the main left bronchus produced complete left pulmonary atalectasis, which required endobronchial stenting. CONCLUSIONS In both cases, rigid bronchoscopy provided a histological diagnosis with diagnosis of Hodgkin's disease in the first case, and identification of recurrence in the other one. These cases are unusual. Such complications are usually complications of radiotherapy. Classically, erosion of mediastinal adenopathy into the bronchial tree is tuberculous in origin but they can be neoplasic.

Abstract
STUDY OBJECTIVES Respiratory failure (RF) is a frequent cause of death among patients with bilateral bronchiectasis. An ICU admission is commonly required, and neither short-term or long-term outcomes have been studied. DESIGN We performed a retrospective study over a 10-year period (January 1990 to March 2000). All patients with bilateral bronchiectasis admitted for the first time in the medical ICU for RF were reviewed. Patients with cystic fibrosis were excluded. MEASUREMENTS AND RESULTS Forty-eight patients (mean age +/- SD, 63 +/- 11 years; mean simplified acute physiology score [SAPS] II, 32 +/- 12) of whom 25% received long-term oxygen therapy (LTOT) were identified. All the patients were treated with intensive medical care, associated with noninvasive ventilation in 13 patients (27%), and 26 patients (54%) required intubation. Nine patients (19%) died in the ICU. The 1-year mortality rate was 40%. Among the variables recorded at ICU admission, age > 65 years (p = 0.002), SAPS II score > 32 (p = 0.012), use of LTOT (p = 0.047), and intubation (p = 0.027) were associated with reduced survival in univariate analysis by Cox regression. Multivariate analysis by Cox proportional hazard model showed that age > 65 years (relative risk [RR], 2.70; 95% confidence interval [CI], 1.15 to 6.29) and use of LTOT (RR, 2.52; 95% CI, 1.15 to 5.54) were independently associated with reduced survival. CONCLUSIONS We performed the first study providing information related to the impact of the first ICU stay for RF on long-term outcomes for patients with bilateral bronchiectasis. Age > 65 years and prior use of LTOT were associated with reduced survival.

Abstract
This work concerns the level of anti-gluten IgA in Coeliac disease, following subjects who have already been diagnosed by clinical signs, biopsy and measurement of anti-gluten IgA. Even if this study had been limited only to a single patient, it would have shown well the clinical sensitivity to these levels, so allowing the following of the development, correlated with improvement of the clinical symptoms with lowering of the level of anti-gluten IgA.
