Assessment of Interstitial Lung Disease in Rheumatoid Arthritis by Lung Ultrasound
Lung DiseasesLung Diseases2 moreThe high resolution chest scan is the gold standard for the screening of interstitial lung disease, but this remains an onerous examination, and irradiating. Ultrasound could be used to detect these disorders with a very good sensitivity and specificity. This exam offers the advantage of being non radiating, inexpensive, and accessible to the rheumatologist who already uses it in their daily practice. The investigators want to assess the lung ultrasound performance compared with the gold standard. Patients will be included during a regular follow-up consultation with their referent rheumatologist. If there is an indication of first line biotherapy or targeted therapy the doctor will propose to the patient to participate in the study, give him the information leaflet, collect orally non-opposition, and will complete a survey for evaluation of the general health and potential risk factors for interstitial lung.
Phenotypes of COPD
Chronic Obstructive Pulmonary DiseaseChronic Obstructive Pulmonary Disease (COPD) has been defined by international guidelines as a common preventable and treatable disease characterized by persistent air flow limitation and respiratory symptoms caused by exposure to gases or noxious particles. COPD is a major cause of morbidity and mortality worldwide. It is predicted to become the third leading cause of death and the fifth leading cause of disability by the year 2020.

Development of Interstitial Lung Disease (ILD) in Patients With Severe SARS-CoV-2 Infection (COVID-19)...
Covid-19Pulmonary FibrosisCOVID-19, the infectious disease caused by the novel coronavirus SARS-CoV-2, currently poses a global economic, social, political and medical challenge. The virus originated in December 2019 in Wuhan, China, and has spread rapidly around the world. Currently, European countries, including Austria, are severely affected.The most common computed tomographic changes in acute lung injury include bilateral and subpleural milk glass opacity, consolidation in lower lobes, or both. In the intermediate phase of the infection (4-14 days after the onset of symptoms) a so-called "crazy paving" may occur. The most prominent radiological changes occur around day 10, followed by gradual resolution, which begins two weeks after the onset of symptoms. Given the phylogenetic relationship between SARS-CoV-1 and SARS-CoV-2, the similar clinical course in severe cases and overlapping CT patterns in the acute setting, persistent radiological and pulmonary functional changes in survivors are conceivable. It is also conceivable that a proportion of survivors will develop progressive ILD, either due to viral or ventilator-induced alveolar damage, or both. Here, the investigators intend to investigate COVID-19 survivors through clinical examinations, functional lung examinations, HR-CT scans, and by determining the "immunofibrotic" pattern in peripheral mononuclear cells (PBMCs) 1, 3, and 6 months after discharge.
Expression of miR-204 and Consequences on Capillarization in Limb Muscles of Patients With COPD...
Chronic Obstructive Pulmonary DiseaseLimb muscle dysfunction, characterized by loss of capillaries, is amongst the most troublesome systemic consequences of chronic obstructive pulmonary disease (COPD) leading to poor functional status and premature mortality. One prevailing hypothesis stipulates that modification in the expression of miR-204 leads to change the regulation of angiogenesis in vastus lateralis of patients with COPD when compared to controls.
Falling in Patients With COPD Referred to Pulmonary Rehabilitation: Incidence, Risk Factors and...
Chronic Obstructive Pulmonary DiseaseThe primary aim of this study is to investigate the incidence of falling in a cohort of patients with chronic obstructive pulmonary disease (COPD) referred to a pulmonary rehabilitation program and to verify the risk factors. The secondary aim is to verify whether available balance assessment tools are feasible in clinical practice and which tools and values can best predict falls in people with COPD.
Acute Exacerbation of Chronic Obstructive Pulmonary Disease Inpatient Registry Study
Chronic Obstructive Pulmonary DiseaseThe purpose of this study is to investigate the demographic characteristics, clinical features, diagnoses and treatments of AECOPD hospitalized patients in China, and disease prognosis and its economic burden.

To Investigate the Inflammasome Response of Inflammatory and Resting MacrophageTo Compare the Difference of Inflammasome Response of Inflammatory Macrophage1 moreTo investigate the inflammasome response of inflammatory and resting macrophage derived from healthy human participants by stimulation using MAC or MAB bacilli. To compare the difference of inflammasome response of inflammatory macrophage by MAC/MAB bacilli stimulation between MAC/MAB-LD patients and the colonizers. To study the diagnostic aid from immunological markers in inflammasome response in inflammatory macrophage stimulated by MAC/MAB.
Detection of Aspergillus Fumigatus and Sensitization in COPD Patients With Bronchiectasis vs Without...
Chronic Obstructive Pulmonary DiseaseA single center case-control study with 100 COPD patients will be organized to compare patients with and without bronchiectasis with regard to the presence of Aspergillus in sputum samples, Aspergillus sensitization and vitamin D. Induced sputum samples will be optimized for culture, Aspergillus galatomannan analysis and RT-PCR. This study is part of a larger project in which we assume that chronic respiratory infection by Aspergillus fumigatus and the accompanying immune response play an important role in the development of bronchiectasis in COPD. We suspect that this mechanism is controlled by vitamin D and it fails by suppression of the vitamin D receptor by Aspergillus fumigatus. The present study is designed by the Laboratory of pneumology and will be conducted in collaboration with the Laboratory of clinical bacteriology and mycology of the Catholic University of Leuven.
Muscle Atrophy In Patients With Chronic Obstructive Pulmonary Disease
Chronic Obstructive Pulmonary DiseaseLimb muscle dysfunction, characterized by atrophy and weakness, is amongst the most troublesome systemic consequences of chronic obstructive pulmonary disease (COPD) leading to poor functional status and premature mortality. One prevailing hypothesis stipulates that the deterioration in muscle structure and function during COPD results from a spillover of inflammatory mediators from the lungs to the systemic circulation and then to the muscles.
