Filter by:Inflammation mediated by macrophage infiltration plays a vital role in a diverse range of physiological conditions. In particular, recent evidence suggests this type of macrophage response is important for the disease pathology of pulmonary fibrosis. Because cysteine cathepsins are proteases that are highly expressed in antigen presenting cells such as macrophages, they serve as promising biomarkers. Employing non-invasive imaging agents 68Ga-BMV101 that specifically recognize cysteine proteases in immune cells has the potential to not only aid early detection but also significantly aid efforts to monitor progression and patient response to therapy.
The purpose of this study is to determine whether magnetic resonance imaging (MRI) using inhaled hyperpolarized 129Xe gas, and conventional contrast can help visualize impaired lung function and detect changes over time in patients receiving treatment as well as those who don't. 129Xe is a special type of xenon gas and when inhaled during MRI may be able to show areas of abnormal thickening of parts of the lungs. These images combined with images taken with injected contrast agents or other types of MRI may provide a better way to look at lung structure and function in patients with IPF. The ultimate goal is to predict how a particular patient might respond to a particular therapy and to observe such responses earlier than conventional tests. The investigators anticipate that the images acquired in this study will provide more specific information about lung disease than standard lung function tests. The use of 129Xe MRI is investigational. "Investigational" means that these tests have not yet been approved by the US Food and Drug Administration and are being tested in research studies like this one. In addition, standard MRI with contrast is not typically done as standard of care for monitoring progression of IPF, therefore, its use in this study is also considered investigational. Healthy volunteers are being asked to participate in this study because the investigators need to develop a database of functional images that are representative of healthy lungs.
This study assesses the tolerability of a single dose of gefapixant (AF-219) in participants with idiopathic pulmonary fibrosis (IPF). Six eligible participants will receive a single 150 mg dose of gefapixant and undergo tolerability and PK assessments.
Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is a major event of IPF with an annual incidence between 5 and 10% and is responsible for the death of one third of IPF patients. When AE-IPF occurs, it is associated with poor survival with an overall mortality at 3 months upper of 50%. To date, no treatment has been proved to be effective in AE-IPF but the efficacy of cyclophosphamide (CYC) on survival has been suggested, mainly by retrospective series and needs to be confirmed. This confirmation is mandatory to improve prognosis of AE-IPF but also to avoid unsuspected deleterious effect as it as been shown with immunosuppressor in stable IPF.
This study is investigating the reliability of the 4 metre gait speed test (4MGS) in patients with a lung disease called Idiopathic Pulmonary Fibrosis (IPF).
The combined pulmonary fibrosis and emphysema syndrome (CPFE) individualized by our group in 2005 is characterized by an often severe dyspnea, almost exclusive male predominance, and often major, profound impairment of gas exchange contrasting with preserved lung volumes and absence of airflow obstruction, and a high risk of pre-capillary pulmonary hypertension responsible for increased mortality. Almost all patients are smokers or ex-smokers. There are some arguments in favor of genetic abnormalities in this syndrome of unknown etiology (other than smoking) including short telomeres and mutations in the telomerase complex genes. There are also emphysematous lesions, in patients with familial pulmonary fibrosis, with mutations in the SFTPC gene (surfactant protein C), and reported cases of CPFE syndrome with SFTPC mutation. No large genetic studies have been conducted to date in the CPFE syndrome. Our main hypothesis is that the proportion of subjects with short telomeres is higher among patients with CPFE syndrome than in subjects of similar age with idiopathic pulmonary fibrosis but without emphysema. It has previously been shown that mutations in the telomerase TERT or TERC genes are mostly found in people whose telomeres are abnormally short. The investigators propose to use that test to identify patients most likely carrying a mutation, and to seek, among them, the mutations in the TERT or TERC telomerase genes. The objective of the study is to compare the proportion of patients with short telomeres in the group of patients with CPFE syndrome to that of other patients (with idiopathic pulmonary fibrosis without emphysema, or with emphysema without fibrosis).
The aim of the study is to answer the question whether a disease specific profile of breath in patients with idiopathic lung fibrosis can be detected by an untargeted metabolomic study using exhaled breath analysis by mass spectrometry.
This study investigates whether usual walking speed, measured by the 4 metre gait speed test (4MGS), and change in usual walking speed over 6 months predicts death and hospital admissions in patients with Idiopathic Pulmonary Fibrosis.
There is established evidence that adult patients with Cystic Fibrosis (CF) may have altered antibiotic pharmacokinetics compared with non-CF patients. Ceftolozane/Tazobactam is a newly approved broad spectrum intravenous antibiotic, which has potent in vitro activity against multidrug resistant Pseudomonas aeruginosa, the most common pathogen implicated in CF pulmonary exacerbations. This study will determine the pharmacokinetics and tolerability of ceftolozane/tazobactam in 20 adult CF patients admitted for a pulmonary exacerbation at one of 4 participating hospitals in the US. Patients will remain on standard of care IV antibiotics and receive 4-6 doses of ceftolozane/tazobactam 3 grams every 8 hours. Blood will be sampled after the final dose to determine concentrations and pharmacokinetics of ceftolozane and tazobactam. Safety and tolerability will be assessed throughout the 3 day study.
The purpose of the PaTH Network IPF Clinician-Patient Partnership Cohort is to use clinical data from electronic health records (EHR) and patient reported outcomes (PRO) to answer questions of clinical importance to patients with Idiopathic Pulmonary Fibrosis, providers, and other stakeholders.
