Brief Summary

This study will collect fluid and tissue samples from the bronchi (air passages to the lungs) of patients with Wegener's granulomatosis for laboratory examination. 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. Patients 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. Participants 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. At the time of the bronchoscopy, patients in this study will undergo the following additional procedures:

• Bronchoalveolar 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 A sample of the fluid is then withdrawn and examined for infection, inflammatory cells and inflammatory chemicals.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.)
• Bronchial lavage - This procedure is similar to bronchoalveolar lavage, but less fluid is used to rinse larger airways.
• Bronchial 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. The 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. Patients 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.
