Wegener's granulomatosis is a type of vasculitis (blood vessel inflammation) that can affect many parts of the body, including the brain, nerves, eyes, skin, sinuses, kidneys, intestinal tract, joints, heart, lungs and other sites. About 85 percent of patients have lung involvement. The lining of the bronchi (bronchial mucosa) is composed of cells that produce mucus, inflammatory cells, and inflammatory mediators (chemicals produced in response to inflammation). Analysis of these various substances may provide insight into what causes different types of lung problems in Wegener's granulomatosis.\n\nPatients between 18 and 75 years of age with Wegener's granulomatosis who require bronchoscopy to evaluate the cause of their lung problem may be eligible for this study.\n\nParticipants will undergo a bronchoscopy in the hospital intensive care unit (ICU). For this procedure, the mouth and throat are numbed with lidocaine jelly and spray. If needed, a sedative is given for comfort. A small plastic tube (intravenous catheter) is placed in a vein to give medications. A pencil-thin tube is then placed through the nose or mouth into the lung airways to examine the airways carefully.\n\nAt the time of the bronchoscopy, patients in this study will undergo the following additional procedures:\n\nBronchoalveolar lavage - Saline (salt water) is injected through the bronchoscope into the air passage, acting as a rinse. A sample of the fluid is then withdrawn and examined for infection, inflammatory cells and inflammatory chemicals. (This may be done as part of the standard medical care procedure.)\nBronchial lavage - This procedure is similar to bronchoalveolar lavage, but less fluid is used to rinse larger airways.\nBronchial mucosal biopsies - A small wire is inserted through the bronchoscope next to the bronchial lining. Forceps at the end of the wire pinch off a small piece of tissue for withdrawal and examination.\n\nThe patient's heart rhythm and rate and oxygen levels are monitored during the procedure. When the procedures are finished, the patient is monitored in the ICU until the numbing effect of the anesthetic has worn off and then moves to a regular hospital bed for overnight.\n\nPatients whose test results show an isolated infection or isolated Wegener's lung tissue involvement and who are being treated or are eligible for treatment under another NIH protocol will be followed by X-ray for improvement of their infection or other lung involvement with treatment. Patients whose infection or lung tissue involvement improves may be asked to undergo a second bronchoscopy as described above, but for research purposes only.", "DetailedDescription"=>"Wegener's granulomatosis is a systemic vasculitis in which parenchymal and/or endobronchial inflammation frequently occur. The purpose of this investigation is to analyze bronchial and bronchoalveolar lavage fluid in patients with Wegener's granulomatosis for the presence of immunoregulatory mediators and pro-inflammatory cytokines. We will also be examining mucosal biopsies in these patients to define the histologic changes, the phenotype of infiltrating leukocytes, and the pattern of adhesion molecule expression that may be present. Such studies could lead to an improved understanding of the pathophysiology of this disease and of its pulmonary manifestations and provide potential directions for future therapy."}, "EligibilityModule"=>{"Gender"=>"All", "StdAgeList"=>{"StdAge"=>["Child", "Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"INCLUSION CRITERIA:\n\nDiagnosis of Wegener's granulomatosis based on clinical and histological characteristics.\n\nAge between 18-75 years.\n\nBronchoscopy is required as part of their standard medical care.\n\nFEV1 is greater than 55 percent of FVC.\n\nO2 saturation is greater than 90 percent.\n\nEXCLUSION CRITERIA:\n\nFEV1 is less than 55% of FVC.\n\nO2 saturation is less than 90%.\n\nAbnormal PT, PTT, or platelet count less than 50.\n\nHistory of adverse reaction to lidocaine or other local anesthetics.\n\nPregnancy."}, "IdentificationModule"=>{"NCTId"=>"NCT00001541", "BriefTitle"=>"Analysis of Bronchial Tissue and Fluid in Patients With Wegener's Granulomatosis", "Organization"=>{"OrgClass"=>"NIH", "OrgFullName"=>"National Institutes of Health Clinical Center (CC)"}, "OfficialTitle"=>"Analysis of Bronchial and Bronchoalveolar Lavage Fluid and Bronchial Mucosal Biopsies in Patients With Wegener's Granulomatosis", "OrgStudyIdInfo"=>{"OrgStudyId"=>"960065"}, "SecondaryIdInfoList"=>{"SecondaryIdInfo"=>[{"SecondaryId"=>"96-I-0065"}]}}, "ContactsLocationsModule"=>{"LocationList"=>{"Location"=>[{"LocationZip"=>"20892", "LocationCity"=>"Bethesda", "LocationState"=>"Maryland", "LocationCountry"=>"United States", "LocationFacility"=>"National Institute of Allergy and Infectious Diseases (NIAID)"}]}}, "SponsorCollaboratorsModule"=>{"LeadSponsor"=>{"LeadSponsorName"=>"National Institute of Allergy and Infectious Diseases (NIAID)", "LeadSponsorClass"=>"NIH"}}}}}}
