BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a chronic lung disorder of unknown origin, which ultimately leads to death. Several growth factors such as IGFs (insulin-like-growth factor) and IGFBPs (insulin like growth factor binding proteins) seem to take part to the pathogenesis. We evaluated IGFs and IGFBPs in serum from patients with IPF and healthy subjects including 24 untreated IPF and 26 IPF receiving anti-fibrotic therapy and to compare them with healthy subjects. METHODS: Serum of 50 idiopathic pulmonary fibrosis and 55 healthy subjects (HS) were analysed by ELISA for IGFs and IGFBPs, TGF-beta and KL-6, the latter being tested as positive control in IPF. RESULTS: Serum levels of IGFBP-1 and IGFBP-2 and KL-6 were significantly higher in the IPF group than in the healthy subjects (p < 0.05, p < 0.001 and p < 0.0001 respectively) while the picture was inversed regarding IGFs. By contrast there was no significant difference between the groups with respect to TGF-beta. IGFBP-2 was significantly reduced in the patients with specific anti-fibrotic therapy pirfenidone and nintedanib compared to untreated patients (p < 0.05) but still significantly elevated in comparison to HS (p < 0.001). CONCLUSION: Serum IGFBP-1 and -2 are increased in idiopathic pulmonary fibrosis and IGFBP-2 may be reduced by anti-fibrosing therapy. IGFBPs may be promising biomarkers in IPF. [less ▲]

Summary : Non small cell lung cancer is the most frequent type of lung cancer and its prognosis is still very poor. Relapse is frequent and can be observed even in early stages of the disease, in spite of a surgical management with curative intent. This paper gives an overview of the main prognostic factors, the two most important of which remain the staging and tumor histology. These also determine the therapeutic strategy. Other factors of poor prognosis might also be useful for clinicians, particularly in their decision to refer patients for adjuvant therapies.

Objective and Importance: Yellow nail syndrome (YNS) is a rare disorder of unknown aetiology characterized by the triad of yellow nails, lymphoedema and respiratory manifestations. About 200 cases have been reported, but a lot of patients probably elude proper diagnosis because of both variability of symptoms and ignorance of this syndrome by many physicians. The pathogenesis remains unclear, and could involve functional lymphatic abnormalities, microvasculopathy or lymphocyte deficiency, but none of these hypotheses seems fully satisfactory. Clinical Presentation: We report for the first time two cases of YNS associated with multiple myeloma relapsing after non-myeloablative haematopoietic cell transplantation (HCT). In these two cases, onset or worsening of YNS symptoms followed graft-versus-host disease (GvHD) manifestations. Intervention: Corticosteroids given to treat GvHD also improved YNS manifestations. Conclusion: YNS after HCT might be a microvascular manifestation of endothelial GvHD and corticosteroids might be an effective treatment. [less ▲]

Emphysema is characterized by an irreversible alveolar destruction, a progressive lung hyperinflation and a dysfunction of respiratory muscles. It induces a respiratory functional limitation and a decrease of quality of life. Endoscopic lung volume reduction represents a potential alternative to surgical treatments for advanced heterogeneous emphysema without concomitant surgical morbidity. The different bronchoscopic systems for lung volume reduction currently under evaluation are presented. [less ▲]

Résumé : Le but de ce travail était d’évaluer la prévalence et de décrire les caractéristiques du phénotype mixte BPCO-asthme parmi les patients BPCO stables de stade II à IV selon la classification de GOLD. Matériel et méthodes : entre mai 2013 et avril 2014, 46 patients consécutifs furent recrutés à partir des consultations de Pneumologie du CHU de Liège. Ils étaient considérés comme présentant un syndrome mixte BPCO-asthme si leur indice de Tiffeneau était < 70% après bronchodilatation et s’accompagnait soit d’un antécédent d’asthme avant l’âge de 40 ans, soit d’au moins deux des trois critères suivants: 1) réversibilité bronchique significative (changement du VEMS après la bronchodilatation ≥ 200 ml et ≥ 12%), 2) inflammation éosinophilique: éosinophiles dans les expecto-rations ≥ 3% ou/et éosinophiles dans le sang ≥ 400/μl ou/et FENO ≥ 45 ppb, 3) histoire d’allergie respiratoire, ou IgE sériques totales ≥ 113 KU/l, ou RAST ≥ 0,35 KU/l à l’égard d’un des principaux aéroallergènes. Le phénotype mixte BPCO-asthme fut observé chez 37% des patients. L’expression symptomatique était plus marquée dans le groupe de phénotype mixte que dans le groupe de BPCO pure (CAT 24,6 ± 8,1 vs 19,4 ± 8, p < 0,05) en dépit d’un déficit spiro-métrique identique. Le coefficient de transfert alvéolo-capillaire (DLCO/VA%) était préservé dans le phénotype mixte (97 ± 24%) et supérieur à celui mesuré chez les patients BPCO pure (80 ± 20%) (p < 0,05). La prévalence du phéno-type mixte est voisine d’un tiers chez les patients BPCO et ces sujets ont une expression symptomatique plus marquée, sans signe d’obstruction bronchique plus sévère. [less ▲]

Patients undergoing hematopoietic stem cell transplantation (HSCT) display an airway neutrophilic inflammation before the transplantation that persists over the years. In this study, we have investigated the cytokine profile over a period of one year in sputum supernatant of patients who underwent HSCT. We have measured sputum supernatant levels of TNF-α, TGF-β1, IL-4, IL-5, IL-6, IL-8, IL-10, IL-13, IL-17, and IFN-γ in 49 HSCT patients and compared the results with those found in 40 COPD and 54 healthy subjects matched for age. Compared to healthy subjects, before the transplantation, HSCT patients exhibited raised levels of IL-6 (p<0.001) and IL-8 (p<0.05) while the other cytokines were generally poorly detectable. This picture was rather similar to what is seen in COPD even if cytokine levels were much greater in the latter with IL-8 being significantly greater in COPD than in HSCT patients (p<0.0001). In the 1 year following the transplantation, sputum IL-6 and IL-8 did not differ any longer compared to healthy subjects. Overall in HSCT patients, sputum IL-8 and IL-6 correlated with sputum neutrophil counts (r=0.4, p<0.0001; r=0.42, p<0.0001, respectively). In conclusion, sputum IL-6 and IL-8 may play a role in neutrophilic airway inflammation seen in patients undergoing HSCT. [less ▲]

BACKGROUND: Neutrophils have been involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). Underlying mechanisms of neutrophil accumulation in the airways of stable and exacerbated COPD patients are poorly understood. The aim of this study was to assess exhaled breath condensate (EBC) neutrophil chemotactic activity, the level of two chemoattractants for neutrophils (GRO-alpha and LTB4) during the course of an acute exacerbation of COPD (AECOPD). METHODS: 50 ex smoking COPD patients (33 with acute exacerbation and 17 in stable disease) and 20 matched ex smoking healthy controls were compared. EBC was collected by using a commercially available condenser (EcoScreen(R)). EBC neutrophil chemotactic activity (NCA) was assessed by using Boyden microchambers. Chemotactic index (CI) was used to evaluate cell migration. LTB4 and GROalpha levels were measured by a specific enzyme immunoassay in EBC. RESULTS: Stable COPD and outpatients with AECOPD, but not hospitalized with AECOPD, had raised EBC NCA compared to healthy subjects (p < 0.05 and p < 0.01 respectively). In outpatients with AECOPD EBC NCA significantly decreased 6 weeks after the exacerbation. Overall EBC NCA was weakly correlated with sputum neutrophil counts (r = 0.26, p < 0.05). CONCLUSIONS: EBC NCA rose during acute exacerbation of COPD in ambulatory patients and decreased at recovery. While LTB4 seems to play a role both in stable and in exacerbated phase of the disease, the role of GRO-alpha as a chemotactic factor during AECOPD is not clearly established and needs further investigation.

Chronic Obstructive Pulmonary Disease (COPD) is a multi-dimensional disorder with multiple phenotypes. The GOLD guidelines, used for the diagnosis, staging and treatment of COPD, do not fully reflect the heterogeneous nature of the disease. Historically, the two most recognized clinical phenotypes of COPD are emphysema and chronic bronchitis. Most COPD patients encountered in practice actually share, both of these features. Genetic background, clinical presentation, variation in the response to treatment and propensity to exacerbations may also identify other phenotypes. Recently, using a mathematical approach, such as cluster analysis, which is based on pre-selected parameters, other interesting phenotypes were identified. A precise definition of COPD phenotypes should lead to a more targeted therapeutic approach based on these phenotypes. The purpose of this article is to point out that COPD is a heterogeneous disease and to summarize the current data available about the phenotypes of this disease. [less ▲]

Chronic obstructive pulmonary disease (COPD) is a multi-dimensional disorder. The recent years, in Vietnam, we have been using the guidelines of GOLD in almost the respiratory departments. According to the GOLD guidelines, in such group A, B, C, D, we have the same treatments for each one. In fact, the genetics, the clinical presentations, the examination features of COPD is very various; these lead to the variety of the response to treatment and the propensity to exacerbations. So, we recognizethe existence of different phenotypes of COPD. In this article, we would like to update the knowledge of COPD phenotypes, based on the current data available to our community of respiratory. Hoping it will be helpful for clinical practice.

Chronic obstructive pulmonary disease (COPD) is an obstructive and progressive airway disease associated with an important reduction in daily physical activity and psychological problems that contribute to the patient's disability and poor health-related quality of life (HRQoL). Nowadays, pulmonary rehabilitation (PR) plays an essential role in the management of symptomatic patients with COPD, by breaking the vicious circle of dyspnea-decreased activity-deconditioning-isolation. Indeed the main benefits of comprehensive PR programs for patients with COPD include a decrease in symptoms (dyspnea and fatigue), improvements in exercise tolerance and HRQoL, reduction of health care utilization (particularly bed-days), as well as an increase in physical activity. Several randomized studies and meta-analyses greatly established the benefits of PR, which additionally, is recommended in a number of influential guidelines. This review aimed to highlight the impact of PR on COPD patients, focusing on the clinical usefulness of PR, which provides patients a good support for change. [less ▲]

Objective: To assess the outcomes of a 6-month comprehensive multidisciplinary outpatient pulmonary rehabilitation programme in patients with chronic obstructive pulmonary disease according to age. Design: Prospective cohort study. Patients: A total of 140 patients with chronic obstructive pulmonary disease (Global Initiative for Chronic Obstructive Lung Disease (GOLD) 3-4) admitted to our centre for pulmonary rehabilitation. Methods: Patients were divided into 3 groups: group A (< 65 years), group B (65-74 years) and group C (>/= 75 years). All the patients received an education and individualized training programme. Pulmonary rehabilitation efficacy was evaluated at 6 months of treatment and 12 months post-treatment. Results: A total of 116 patients completed the pulmonary rehabilitation programme: 59 in group A (85.5%), 40 in group B (80%) and 17 in group C (80.9%). All the parameters studied (number of sessions, 6-min walking distance, isometric quadriceps strength, health-related quality of life, maximal load, peak oxygen uptake, maximal inspiratory and expiratory pressures) were significantly improved in each of the groups at 3 and 6 months compared with baseline. Moreover, percentage changes from baseline at 6 months for all of the parameters studied were not significantly different between age-groups. Conclusion: Pulmonary rehabilitation is efficient in elderly patients with severe and very severe chronic obstructive pulmonary disease, and their compliance with pulmonary rehabilitation was similar to that seen in younger groups. Therefore, elderly patients with chronic obstructive pulmonary disease should not be denied pulmonary rehabilitation. [less ▲]

We now have access to a large library of publications validating transparietal thoracic echography in various clinical situations. Parietal lesions, including osteolysis, can be detected and biopsied during the thoracic ultrasound (TUS) examination. To evaluate the parietal extension of lung cancers, TUS has proved superior to tomodensitometry. Pleural effusions can be easily diagnosed and aspirated. Pneumothoraces can be detected using well defined lung artifacts with a high frequency probe. Pleural and peripheral lung nodules can be detected and biopsied with real time visualization; the procedure is safe and accurate. Lung consolidations with a pleural contact can be diagnosed; this is particularly useful for pregnant women. In conclusion, TUS is a precious diagnostic tool for chosen applications, and can help to guide interventional procedures. The portable devices are also very useful for bedridden patients or for out of hospital use. [less ▲]

Asthma is a complex disease highly dependent of environmental exposure and genetic background. Through linkage analysis, positional cloning and genome wide association studies, novel asthma genes have come out such as ADAM-33 or ORMLD3. Important environmental factors include allergenic exposure, pollutants and especially particulate matters, tobacco, aerosol exposure, viral infections and level of exposure to endotoxin. The effects of environmental factors are modulated by the genetic sequence and numerous single nucleotide polymorphisms (SNPs). Recently, it has also become clear that environmental factors may alter gene expression by DNA methylation or histone methylation/acetylation without changing the gene sequence and thereby changing asthmatic phenotype.
