This study will examine the different types of proteins present in the lungs of patients with pneumonia to explore the causes of different types of the disease. Pneumonia is a condition that causes lung inflammation AND is often caused by an infection. It is usually diagnosed by lung x-rays and listening to the chest with a stethoscope. This method can diagnose pneumonia, but it does not provide information on the cause of the inflammation - information that might be helpful in guiding treatment. This study will measure proteins in the lungs of patients to see if certain proteins are associated with specific forms of pneumonia, and can thus serve as biomarkers for disease. Patients undergoing diagnostic bronchoscopy at the NIH Clinical Center may participate in this study. Patients will undergo bronchoscopy and bronchoalveolar lavage as scheduled for their medical care. For this procedure, the patient's mouth and throat are numbed with lidocaine; a sedative may be given for comfort. A thin flexible tube called a bronchoscope is advanced through the nose or mouth into the lung airways to examine the airways carefully. Saline (salt water) is then injected through the bronchoscope into the air passage, acting as a rinse. A sample of fluid is then withdrawn for microscopic examination. Researchers in the current study will use some of the fluid obtained from the lavage to examine for protein content. In addition to the bronchoscopy and bronchoalveolar lavage, participants will have about 2 tablespoons of blood drawn to compare blood test results with the results of the lung washings. Patients' medical records will be reviewed to obtain information on past medical history, current medical treatment, vital signs, and results of x-ray tests.
To characterize the development of tobacco control capacity with staff from the Chinese Center's for Disease control (CDCs) at the provincial level and to have them develop and implement population-level interventions to build awareness and knowledge concerning the harms of smoking that could help lead to policy action being taken to protect the population from the harms caused by smoking. Compare capacity, policy and, second-hand smoke exposure and smoking rates in selected provinces to national levels.
Open-label therapy will be administered to up to 220 patients, following completion of either InterMune Protocol GIPF-002 Part B or Protocol GIPF-004, to assess the long-term safety of subcutaneous Interferon gamma-1b. The study duration will be 5 years.
The purpose of this study is to determine whether roflumilast is effective in the treatment of exacerbations in patients with chronic obstructive pulmonary disease (COPD).
- Purpose: A phase 3, randomized, double-blind, placebo-controlled trial to determine the efficacy and safety of 200 µg of recombinant Interferon gamma-1b administered by subcutaneous (SC) injection, compared with placebo, in patients with IPF - Enrollment: Approximately 800 patients will be enrolled from approximately 80 centers in North America and Europe - Randomization: 2:1 active-to-placebo ratio - Duration: at least 2 years active drug or placebo (rescue therapy will be permitted for patients who meet predefined criteria)
The goal of this clinical research study is to learn if the drug nesiritide (Natrecor) is effective in lowering the pressure in your lungs. The primary objective of this study is to establish that Nesiritide (Natrecor) is effective in reducing pulmonary hypertension (PHTN) acutely as measured by a 20% reduction in the mean pulmonary arterial (PA) pressure. The secondary objectives will include: improvement in pulmonary vascular resistance (PVR), patient symptoms, exercise tolerance, frequency of toxicity, and surgeon's willingness to proceed with operation.
