Active clinical trials for "Pulmonary Fibrosis"

The overall aim of this study is to develop a test that predicts the prognosis of IPF (Idiopathic Pulmonary Fibrosis) and which could be used to determine whether new treatments for IPF are likely to work.

Influenza A (H1N1) v2009 infection was responsible throughout the world of viral pneumonia and severe pulmonary edema requiring rescue therapeutics such as extracorporeal oxygenation. To date, no data exist on the outcome of patients having developed acute respiratory distress syndrome (ARDS) due to influenza A (H1N1) v2009, and in particular in patients with very severe lung injury requiring extracorporeal oxygenation. Although data exist on long-term outcome of survivors of ARDS, the patients included in the observational studies were heterogeneous with various underlying disease. Moreover, no study compared the outcome of survivors of ARDS according to the need or not of extracorporeal oxygenation. We therefore conducted this prospective case-control study to compare the long term pulmonary and extra pulmonary function in 2 groups of patients, one with severe ARDS due to H1N1 requiring extracorporeal oxygenation (case), and the second with ARDS due to H1N1 but without need for extracorporeal oxygenation (control). Eighteen case patients with inclusion and without non-inclusion criteria were selected from our national registry, and 32 controls (with inclusion and exclusion criteria) were matched on age, sex, and body mass index. All 48 patients will be contacted and asked to participate. Patients will be evaluate at least 9 months after ICU discharge, looking for health-related quality of life, measured by the Medical Outcomes Study 36-item Short-Form General Health Survey (SF-36), post traumatic stress disorder, assessed by the Impact of Event Scale Anxiety, and depression, assessed by the Hospital and Depression Score. Pulmonary function testing, including VO2 max test on a static bike will be performed. Muscle weakness will be clinically evaluated by the medical council research (MRC) test, with an additional electromyography if the result of the test was <48/60. A CT-scan will be performed, looking for lung abnormalities (fibrosis...). Albumin and prealbumin will be measured to evaluate the nutritional status. Primary outcome measurement is carbon monoxide diffusion capacity. The primary hypothesis is that patients with extracorporeal oxygenation will have a carbon monoxide diffusion capacity lower than patients without extracorporeal oxygenation (15% difference between groups). Inclusion of 13 patients in the case group and 26 patients in the control group will allow testing this hypothesis with a statistical power of 80% (standard deviation 15%). Secondary outcome measures will be the quality of life, the presence or not of post-traumatic stress disorders, of anxiety and/or depression, the results of pulmonary function testing, of the CT-scan, and of muscle testing. All results will be compared in patients with and without extracorporeal oxygenation.

To determine risk factors for idiopathic pulmonary fibrosis.

To investigate the ability of machine learning models based on radiomic features extracted from thin-section CT images to differentiate IPF patients from non-IPF interstitial lung diseases.

Idiopathic pulmonary fibrosis (IPF) is a chronic, disabling disease characterized by a progressive and irreversible deterioration in respiratory function, resulting in impaired quality of life (QoL) and patient dependence. The factors involved in the alteration of QoL in these patients are the physical symptoms related to fibrosis (dyspnea, cough, fatigue) and psychological symptoms (anxiety and depression) as well as social, relational and financial factors, the experience of the disease and disability, the time required for diagnosis, the information received, and the initiation of a treatment such as oxygen therapy. Caregivers primarily in chronic diseases (so-called natural or informal caregivers) provide partial or total assistance to a dependent person for activities of daily living for care, social support and maintenance of autonomy, administrative procedures, psychological support, communication, domestic activities or even financial assistance, often despite their own exhaustion and health issues. Recent studies on the QoL of patient-caregiver dyads in IPF through semi-structured interviews highlight the role of previously identified factors in caregivers as well. Investigators want to confirm the data obtained in a large population of patients and their caregivers in order to evaluate the QoL of caregivers and confirm the impact of its various factors on it in order to suggest ways to improve the lives of both the caregiver and the patient. The hypothesis of investigators' work is that the QoL of caregivers of patients with IPF is altered, particularly by the patient's functional symptoms (cough, dyspnea, fatigue, anxiety and depression), the arrival of oxygen therapy in the home and the caregiver's social isolation. Investigators believe that there are links and interactions between the caregiver's and patient's quality of life and therefore have an impact on the patient's care.

Idiopathic pulmonary fibrosis (IPF) is one of the most common chronic idiopathic fibrotic interstitial lung disease (ILD). IPF is an evolving disease that requires regular follow-up through clinical examination, respiratory functional investigations and thoracic CT. Thoracic CT is necessary for the follow-up, usually performed yearly, and in case of deterioration of respiratory function. The disadvantages to its realization are the repeated irradiation, the cost, the accessibility, and sometimes the difficulties of realization related to the supine position. Several signs of thoracic ultrasound have been described in ILD, including the number of B lines, the irregularity of the pleural line, and the thickening of the pleural line. Cross-sectional studies have correlated the intensity of these signs with the severity of fibrosis lesions on chest CT in patients with ILD, including IPF. However, no studies have prospectively described the evolution of ultrasound signs in the same IPF patient, or their correlation to clinical, functional and CT scan evolution. The hypothesis is that thoracic ultrasound is a relevant tool to highlight the evolution of pulmonary lesions in IPF. The main objective is to show with thoracic ultrasound an increase in one or more of the ultrasound signs: line B score, pleural line irregularity score, and pleural line thickness during the follow-up of patient with IPF. The study will enroll patients with a validated diagnosis of IPF in a multidisciplinary staff. At each follow-up visit, patients will have a clinical examination, pulmonary functional test and thoracic ultrasound. The CT data collected will include the last thoracic CT performed in the 3 months before the inclusion and those performed during the patient's participation. The presence, location and severity of ultrasound signs, will be recorded for each patient during successive reassessments and correlation to clinical, functional and CT scan evolution will be made. This study will add significant knowledge in the study of ultrasound signs evolution in patients with IPF. If there is a correlation with the clinical or CT scores, it will be possible to carry over the realization of the CTs to limit the irradiation of the patients. Conversely, early detection of worsening ultrasound signs may lead to faster therapeutic adjustments to limit the extent of irreversible fibrotic lesions.

Idiopathic pulmonary fibrosis is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia of unknown cause, occurring primarily in older adults, limited to the lungs, and associated with the histopathologic and/or radiologic pattern of usual interstitial pneumonia. The definition of Idiopathic pulmonary fibrosis requires the exclusion of other forms of interstitial pneumonia including other idiopathic interstitial pneumonias and Interstitial lung disease associated with environmental exposure, medication, or systemic disease. Prevalence estimates for Idiopathic pulmonary fibrosis have varied from 2 to 29 cases per 100,000 in the general population IPF should be considered in all adult patients with unexplained chronic exertional dyspnea, and commonly presents with cough, bibasilar inspiratory crackles, and finger clubbing.

Multi-center, non-interventional, prospective cohort study aiming to enroll 240 Idiopathic Pulmonary Fibrosis patients receiving treatment with nintedanib in a consecutive manner from 10-12 reference centers across Greece.

The purpose of this study is to compare AI performance to doctor's performance in the evaluation of IPF/UIP and ILDs without UIP(proven by biopsy).

RESOLVE's objective is to identify and characterize validated molecular targets capable of shifting primary organ repair towards fibroproliferative wound healing. Work package 2 (WP2) of RESOLVE includes the clinical study protocols within the RESOLVE system evaluating different forms of pulmonary repair in humans ranging from normal repair over mainly inflammatory to predominantly fibroproliferative repair. Hypothesis Fibrosis of the lung is an aberrant and intensified form of wound healing. It is the result of an unresolved disturbance of both initiation and control of repair which is partly age-related. As a result of the relentlessly activated wound healing reaction, mechanisms of inflammation largely representing the condition of chronic inflammation within the peripheral bronchial tree will aggravate this abnormal form of repair. A systematic comparison of the molecular pathology of fibrotic repair representing Varying intensity of fibrosis related to the pathology of usual interstitial pneumonia (UIP), Varying inflammatory mechanisms (UIP vs. Hypersensitivity pneumonitis [HP], acute and chronic), and Varying stages of age (Normal pulmonary repair in young and old individuals vs. acute/chronic HP vs. UIP) will be able to identify molecules capable of shifting regular repair towards fibroproliferative repair and elucidate their interrelationship with other molecules forming coordinated yet misdirected metabolic responses characteristic for fibroproliferative repair.
