Filter by:The etiology of pulmonary fibrosis is unknown. Analyses of blood, genomic DNA, and specimens procured by bronchoscopy, lung biopsy, lung transplantation, clinically-indicated extra-pulmonary biopsies, or post-mortem examination from individuals with this disorder may contribute to our understanding of the pathogenic mechanisms of pulmonary fibrosis. The purpose of this protocol is to procure and analyze blood, genomic DNA, and specimens by bronchoscopy, lung biopsy, lung transplantation, extra-pulmonary biopsies, or post-mortem examination from subjects with pulmonary fibrosis. In addition, blood, genomic DNA, clinically-indicated extra-pulmonary biopsies, as well as bronchoscopy and post-mortem examination specimens may be procured and analyzed from relatives of subjects with hereditary forms of pulmonary fibrosis; blood, genomic DNA, and bronchoscopy specimens may be procured from healthy research volunteers....
It has been shown that neutrophils (a specific type of cell) are involved in inflammation in the lungs of CF patients. Neutrophil levels in CF patients have been measured by bronchoalveolar lavage (BAL), which samples cells in the fluid lining of the lungs. Other studies have measured neutrophil levels and inflammation in other parts of the body using PET scanning. This study aims to show that PET scanning can be used as a non-invasive marker of inflammation in the lungs of patients with CF, which would be a useful tool in treatment. The primary goal of this study is to draw a connection between the level of inflammation shown in the PET scan and the number of neutrophils obtained from the BAL. This study will also look at how the PET images relate to inflammatory molecules in the lungs and to the FEV-1 obtained through spirometry.
This study is designed to evaluate the genetics involved in the development of lung disease by surveying genes involved in the process of breathing and examining the genes in lung cells of patients with lung disease. The study will focus on defining the distribution of abnormal genes responsible for processes directly involved in different diseases affecting the lungs of patients and healthy volunteers. Optional CT Sub-study The standard CT scan will be compared to the low dose radiation CT scan for the 150 subjects enrolled in the sub-study to assess the variation between the two techniques. Specifically, the quantitative computer aided detection of lung CT abnormalities from LAM can be compared to assess whether low radiation dose CT exams is an alternative to conventional CT to monitor disease status. This optional sub-study will be offered to up to 100 adult subjects with lung disease and up to 50 children age 9 and older with CF. Children will not be enrolled in the optional CT sub-study unless they have had a standard CT scan for medical purposes to use in comparison. One additional low dose radiation CT scan of the chest may be done as part of this sub-study when these subjects have their next annual CT scan.
This is an omnibus protocol for studying patients with cystic fibrosis. The main purpose of the study is to obtain samples and data collected during standard clinical care for future research to expand knowledge of the natural history, clinical manifestations (phenotypes) and the genetic variants (genotypes) of cystic fibrosis....
