Study of Lung Proteins in Patients With Pneumonia
NCT00077909 · View on ClinicalTrials.gov ↗
Study Summary
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 A sample of fluid is then withdrawn for microscopic examination.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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00077909
The ClinicalTrials.gov registry entry for NCT00077909 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 750 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institutes of Health Clinical Center (CC), which has 209 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Pneumonia appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00077909 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
