Pleurisy

This pilot study tests whether the steroid prednisone can prevent recurrent pleural effusions (fluid buildup around the lungs) in people with non-specific pleuritis. Forty adults will be randomly assigned to take prednisone daily for 4 weeks or receive no steroid. The study lasts…

This early-stage study tests a new imaging agent called 18F-4FN for PET scans to safely detect inflammation in the body. It involves 55 adults with cancer who are on immunotherapy or have suspected inflammation. The goal is to see if this agent can highlight areas of inflammation…

This study tests whether using a special microscope (confocal laser endomicroscopy) during a chest camera procedure can better diagnose unexplained pleural disease. About 158 adults with fluid around the lungs that standard tests couldn't diagnose will be randomly assigned to get…

This study is testing a new laboratory method that looks for DNA fragments from tuberculosis bacteria in fluid around the lungs (pleural effusion). The goal is to see if this test can diagnose tuberculous pleurisy more accurately than current tests. Researchers will study 400 adu…

This study looks at how different types of mycobacterial infections, including drug-resistant tuberculosis and nontuberculous mycobacteria, change the body's immune response. Researchers will collect blood and other samples from 120 participants, including healthy people and thos…

This study aims to see if analyzing the chemicals in a child's breath can help diagnose and monitor diseases like asthma, neurological disorders, and type 1 diabetes. Researchers will collect breath samples from up to 3,600 children and teens to find patterns linked to these cond…

This pilot study is measuring prednisolone levels in 120 people with inflammatory diseases like thyroid eye disease, vasculitis, COPD, asthma, and others. Participants take high-dose prednisolone as part of their routine care, and researchers take timed blood samples to see how t…

This study looks at 320 adults who are about to start strong immune-suppressing therapy and have already had at least two COVID-19 shots. Researchers want to find out if giving a COVID-19 booster right before starting therapy or waiting six months provides better protection. Part…
