Filter by:Idiopathic Pulmonary Fibrosis(IPF) is the most common idiopathic interstitial lung disease whose cause is unknown. With age and gender, socio-economic factors are the most influential indicators of health. At present there is very little data on socio-economic factors in the IPF. The investigators hypothesize that a lower socio-economic level and / or exposure to various air pollutants may influence the IPF's natural history, including the severity of diagnosis and prognosis of the IPF. The investigators also hypothesize that the deleterious effect of air pollutants is modulated by individual susceptibility (shorter telomeres) and that this effect is related to oxidative stress and shortening of telomeres.
Study population: Patients with fibrotic lung sequelae after recovery from acute phase of severe COVID19 pneumonia Objectives: To evaluate the effect of pirfenidone administered for 24 weeks in patients who have pulmonary fibrotic changes after suffering severe COVID19 pneumonia, analysed by - % change in forced vital capacity (FVC) - % fibrosis in high resolution computed tomography (HRCT) of the lung
This study plans to learn more about pulmonary fibrosis and how it develops. We want to determine if the disease can be detected early, before the lung is permanently scarred. This study will enroll participants who are not currently diagnosed with pulmonary fibrosis, but who have family members with pulmonary fibrosis. Because there is an increased risk within affected families, this cohort will allow us to learn how pulmonary fibrosis develops, and how the lungs change over time.
Currently, there is no approved treatment for COVID-19 in France, either for the acute phase, nor for the late chronic phase. the investigator suggest that nintedanib has the potential to block the development of lung fibrosis when initiated early enough to inhibit the activation of mesenchymal cells and the progression of virus-induced pulmonary fibrosis. Computerized Tomography (CT) manifestations of fibrosis or fibrous stripes are described in COVID-19 (Ye, Eur Radiol 2020). Pan et al observed fibrous stripes in 17% patients in the early phase of the disease (Pan, Eur Radiol 2020). Ye et al observed bronchiectasis in 2 patients (15.4%) and evidence of pulmonary fibrosis in 3 patients (23.7%) at HRCT performed at 4 weeks (Ye, Eur Radiol 2020). Long term data are still lacking in patients with COVID-19 and the investigators do not know how many patients will have fibrotic sequelae from the acute illness.
This is a first-in-human, two-part, Phase 1 study that will characterize the safety, tolerability, PK, and immunogenicity of HuL001.
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.
SARS-CoV-2 infection induces a hyperinflammatory syndrome, causing the acute respiratory distress syndrome, massive lung cell destruction and, as a plausible sequelae, pulmonary fibrosis in COVID-19 patients. Current focus has been on the development of novel immunosuppressant therapies, in order to control the cytokine storm in COVID-19 patients. Thus, the effect of steroids, intravenous immunoglobulin, non-steroidal immunosuppressants, selective cytokine blockade, JAK/STAT pathway inbhibition, and mesenchymal precursor cells have been evaluated. Based on the above information, we propose COLLAGEN-POLYVINYLPYRROLIDONE (Distinctive name: FibroquelMR, active substance: Collagen-polyvinylpyrrolidone, pharmaceutical form: intramuscular injectable solution, with sanitary registration No. 201M95 SSA IV and SSA code: 010 000 3999) as a potential drug for the downregulation of the cytokine storm. Polymerized type I collagen reduces the expression of IL-1β, IL-8, TNF-alpha, TGF-β1, IL-17, Cox-1, leukocyte adhesion molecules (ELAM-1, VCAM- 1 and ICAM-1), some other mediators of inflammation and increases the levels of IL-10 and the number of regulatory T cells. In addition, it promotes the mechanisms of inhibition of tissue fibrosis, without adverse effects in rheumatoid arthritis and osteoarthritis.
This is a randomized, double-blinded, placebo-controlled, two-arm study to evaluate the safety and efficacy of BIO 300 Oral Suspension (BIO 300) as a therapy to improve lung function in patients that were hospitalized for severe COVID-19-related illness and continue to experience post-acute respiratory complications associated with Long-COVID after discharge. Patients will be randomized 1:1 to receive BIO 300 or placebo.
Extension of the PFBIO cohort which includes patients with newly diagnosed idiopathic pulmonary fibrosis (IPF) for longitudinal follow-up for up to 5 years. In the PFBIO-EXA extension, patients are included if they experience an exacerbation, or other increase in respiratory symptoms requiring hospital admission, for further collection of clinical and biological data.
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.
