Filter by:The increasing incidence of chronic respiratory disease is a public health problem that affects hundreds of thousands of people worldwide at all ages. Directly exposed to atmospheric airborne contaminants (pollution, allergens), the respiratory tract represents a complex ecosystem involving different cells (multiciliated, basal, mucosecretory, neuroendocrine, etc.) that develop complex interactions with the surrounding connective tissue but also with their rich immune environment and the local microbiota. Although a pathophysiological continuum is postulated between the nasal and bronchial airways in certain diseases, such as allergic diseases, investigators have demonstrated large gene expression gradients between samples taken from the nasal and bronchial airways in different studies. Specifying the cellular variability throughout the respiratory tree in a normal physiological situation is one of the major objectives defined in the establishment of an atlas of all airway cells, as defined in the objectives of the international consortium Human Cell Atlas. The sequencing of the RNAs present specifically in each individual cell ("single-cell RNAseq"), and its comparison with neighbouring cells allows to document the precise cellular contributions, as well as the signalling pathways involved. The development of tissue sampling, stabilization, transport and single cell analysis procedures can be performed on primary respiratory epithelium cultures and can also be extended to respiratory samples from healthy volunteers. This project will analyze gene expression profiles at the single cell level (single cell RNAseq) in volunteers with chronic obstructive pulmonary disease, interstitial pulmonary fibrosis and compared to healthy subjects of the same age. The technical modalities of the samples will be brushing and staged airway biopsies for direct analysis of the samples. This approach will be complemented by an air-liquid interface culture to allow secondary analysis in single cell RNAseq and three-dimensional mapping of the distribution of these cells with single cell in situ analysis. Thanks to sampling at several levels of the respiratory tree (nose, bronchioles, bronchioles), cellular and gene expression variations along the tracheobronchial axis will be exhaustively documented in subjects of different ages, healthy or suffering from pathologies such as chronic obstructive pulmonary disease and interstitial pulmonary fibrosis. These data will serve as worldwide references for comparisons in different physiological and pathological contexts.
Pediatric idiopathic pulmonary hypertension has significant morbidity and mortality. An ever expanding body of knowledge indicates the important contribution of inflammation to pathogenesis and successful treatment with glucocorticoids. Over the last several years the investigators have utilized steroids in patients with severe pulmonary hypertension as part of a treatment regimen. These basic science studies possibly identifies a biochemical etiology for the development of disease and may also be impacted by the administration of steroids. Additionally, there is a commercially available assay which tests for all of the above molecules.
The main objective of this study is to evaluate, in vigilant resuscitation patients, the effect of the use of HYPNO VR on the pain felt during the insertion of a thoracic drain.
The aim of this study is to investigate the frequency and implications of pulmonary hypertension in lung cancer patients. To do so, data will be collected from all lung cancer patients at the university hospital Giessen. All data will be analyzed for possible hints of pulmonary hypertension as a comorbidity in lung cancer patients. All information will be generated from the regular guidelines based course of treatment and there will be no interventions. This study will serve as a prospective register for all lung cancer patients treated at the university hospital Giessen.
The impact of fiber intake on short chain fatty acid (SCFA) metabolism has not been studied in subjects suffering from COPD. The purpose of this study is to compare changes in SCFA metabolism after inulin vs. placebo intake in COPD patients to healthy matched controls. This protocol is an extension of a recent study about whole-body SCFA production rates in COPD patients. The investigators hypothesize that a short-term fiber supplementation increases SCFA production in COPD patients.
By the end of 2019 a new coronavirus, named SARS-CoV-2, was discovered in patients with pneumonia in Wuhan, China. In the following weeks and months the virus spread globally, having a tremendous impact on global health and economy. To date, no vaccine or therapy is available. Severe courses of the infection not only affect the lungs, but also other organs like the heart, kidney, or liver. The lack of preexisting immunity might at least partially explain the affection of extra pulmonary organs not yet seen in infections due to other respiratory viruses. In this observational investigation the study group will follow up on patients that have been hospitalized due to a SARS-CoV-2 infection, and monitor sequelae in various organs, with an emphasis on the pulmo-cardiovascular system. Our that in some patients, organ damage will persist and require long-term medical care.
1. Impact of telemonitoring on quality of life (QoL) of patients with CTD-ILD 2. Evaluation of health status of patients with connective tissue disease-associated interstitial lung disease (CTD-ILD) using telemonitoring and standard care. 3. Assessment of treatment response patterns (full remission, partial remission, progression, no response) and evaluation of clinical prognostic factors (risk factors for poor response in patients with CTD-ILD. 4. Evaluation of cost-effectiveness of telemonitoring solutions in patients with CTD-ILD. 5. Evaluation of telemedicine as a tool for assessing the safety of therapy
Acute exacerbations of Chronic Obstructive Pulmonary Disease (COPD) are a major source of morbidity and mortality for patients and cost to the society. In case of acute respiratory failure with hypercapnia and acidosis, Non Invasive Ventilation (NIV) is preferred as a first line treatment. NIV failures are not uncommon, from 15% in intensive care to 25 - 30% in emergency departments. They most often occur at the start of the NIV or in the hours that follow. There are many reasons for these failure. Among these are; dyspnea, discomfort, the pain related to the exacerbation and also to the NIV are frequently noted. The use of certain drugs with anxiolytic, hypnotic and/or analgesic properties could also be useful. Some sedatives and opioids have already been studied in this indication but without a therapeutic trial and satisfactory methodology. Among the molecules of interest, Morphine seems interesting . It's administration could reduce the ventilatory rate, intensity of dyspnea, pain and anxiety as well as dynamic hyperinflation. The investigators believe that morphine administration will decrease the rate of early NIV failure by improving comfort (decreased dyspnea and pain) and ventilation (decreased respiratory rate and increase in tidal volume) in patients with exacerbations of COPD. However, before considering a randomized phase III efficacy study, it is necessary to determine the optimal dose of morphine in this indication, through a phase I/II dose-finding study taking into accounts both the efficacy and toxicity of morphine. The main objective of this study, is to determine the optimal dose of morphine administered at the initiation of NIV in patient with acute Exacerbation of Chronic Obstructive Pulmonary Disease (COPD), which is defined as the maximum gain function combining the probability of dose-limiting toxicity with PaCO2.Therefore, the impact of morphine administration on the physiological parameters of NIV- COPD exacerbation patients will be assessed.
COVID-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.
The primary intention of this study is to determine the diagnostic performance of ultra-low-dose CT (ULDCT) in diagnosis and follow-up of diffuse parenchymal lung disease (DPLD). We hypothesize that inspiratory and expiratory chest ULDCT has comparable diagnostic yield to standard dose chest High-resolution computed tomography (HRCT) and utility for follow-up of patients with known DPLD. We will study this hypothesis through the following aims: 1. Determine whether inspiratory and expiratory ULDCT are comparable to HRCT in identifying mosaic attenuation due to air-trapping. 2. Determine whether ULDCT is as good as HRCT for follow-up of patients with established DPLD to identify disease progression.
