Active clinical trials for "Alveolitis, Extrinsic Allergic"

To our knowledge, there is no randomized controlled trial assessing the efficacy of mycophenolate mofetil (MMF) in the treatment of HP. We aim to perform a randomized study to assess the efficacy and safety of a regimen consisting of MMF and prednisolone against a regimen consisting of prednisolone alone for treating fibrotic HP. We hypothesize that the treatment of patients with fibrotic HP with MMF and prednisolone will be more effective and safer than treatment with prednisolone alone.

This is a prospective exploratory biodistribution study in patients with interstitial lung disease (ILD). The purpose of this research study is to determine where and to which degree the FAPI tracer (68Ga-FAPI-46) accumulates in normal and fibrotic lung tissues of patients with interstitial lung disease. The study will include patients with interstitial lung disease who have or will initiate a new ILD medication OR will undergo tissue biopsy or surgery of the lung. The study will include 30 patients, the upper limit for PET imaging studies conducted under the Radioactive Drug Research Committee (RDRC) purview. Participants will be injected with up to 7 mCi of 68-GaFAPi and will undergo one PET/CT scan and one High Resolution CT of the lungs. The study is sponsored by Ahmanson Translational Theranostic Division at UCLA.

EVITA is a multicentric Latin-American prospective cohort on chronic hypersensitivity pneumonitis. EVITA's objective is to identify phenotypes and/or endotypes associated with different disease trajectories measured primarily by forced vital capacity (FVC) during a 24 month follow-up period. Other secondary measures of disease progression will also be investigated such as imaging, time to death or lung transplantation, and patient-reported outcomes

Up to 135 patients with hypersensitivity pneumonitis will be enrolled at 7 clinical centers across the United States. Patients will be followed for 24 months to determine if biomarkers in the blood can predict disease progression.

Data and specimens will be collected longitudinally from patients seen in the UVA Interstitial Lung Disease (ILD) clinic in order to describe the phenotypic expression of various interstitial lung diseases. Samples will also be collected from a control group for comparison purposes. All data will be entered into a repository for future research purposes or screening for new studies that become available. This data will help identify trends and hopefully lead to a better understanding of the disease progression, treatment options, and outcomes.

Stop exogenous allergic alveolitis (EAA) in childhood: healthy into adulthood - a randomized, double-blind, placebo-controlled, parallel-group study to evaluate prednisolone treatment and course of disease. The hypothesis of the study is that the treatment with placebo will not be inferior in terms of Forced Vital Capacity (FVC) improvement than treatment with systemic steroids after 6 months treatment.

Establish a interstitial lung disease (ILD) registry and biorepository to lead towards a further understanding of the disease.

The investigators aim to examine the genetic determinants of interstitial lung disease in a cohort of subjects with regular exposure to pigeons, a known cause of one form of interstitial lung disease known as hypersensitivity pneumonitis. In addition we will examine immunological causes for hypersensitivity pneumonitis in this group. We anticipate our work will provide insights of use to clinicians and patients with hypersensitivity pneumonitis and other interstitial lung diseases.

Sub-study of the main Pulmonary Fibrosis Biomarker (PFBIO) cohort (NCT02755441), recruiting patients with an MDT-diagnosis of hypersensitivity pneumonitis (HP). Patients are included for the collection of blood samples and regular clinical data. The database and biobank will be available for studies of HP, and can be directly compared to the main PFBIO cohort, which has recruited patients with Idiopathic pulmonary Fibrosis (IPF) since 2016. Biomarkers will be assessed as diagnostic and prognostic. Further subtyping of HP, based on blood markers (including precipitins) will also be possible with the PFBIO-HP project.

Dyspnea (i.e. breathlessness) and exercise intolerance are common symptoms for patients with interstitial lung disease (ILD), yet it is not known why. It has been suggested that muscle dysfunction may contribute to dyspnea and exercise intolerance in ILD. Our study aims to: i) examine differences in the structure and function of the leg muscles in ILD patients, ii) determine if leg muscle fatigue contributes to dyspnea and exercise limitation in patients with ILD, and iii) determine the effects of breathing extra oxygen on leg muscle fatigue, as well as ability to exercise in ILD patients.
