Pulmonary Hemorrhage

This clinical trial aims to compare two different ways of giving a medication called tranexamic acid to patients who are coughing up blood (a condition known as hemoptysis). Coughing up blood can be a serious medical issue that needs to be stopped quickly. Tranexamic acid is a well-known medication that helps blood to clot and stops bleeding. Usually, this medication is given through an intravenous (IV) line directly into a vein. However, doctors are now studying if giving the medication through a breathing mask (nebulizer) might work just as well or better. A nebulizer changes the liquid medicine into a fine mist so the patient can breathe it directly into their lungs, targeting the exact area where the bleeding is happening. To find out which method is better, researchers will randomly assign 170 adult patients who come to the hospital coughing up blood into two equal groups: Group 1: Will receive the tranexamic acid medication inhaled through a nebulizer mask. Group 2: Will receive the tranexamic acid medication through a standard IV line. The main goal of the study is to see which treatment is more successful at completely stopping the bleeding within 24 hours. Researchers will also closely monitor the patients to see how quickly the bleeding stops, how long patients need to stay in the hospital, and if there are any side effects from either treatment method.

This study aims to understand the role of extracellular vesicles (EVs) in extremely premature infants, those born before 28 weeks of gestation. EVs are tiny particles released by cells that carry important information about the body's condition. In extremely premature infants, blood vessels may not function properly, leading to serious health problems such as bleeding in the brain, lung injury, or severe infections. Researchers believe that analyzing EVs in the umbilical cord blood of these infants may help predict which babies are at higher risk of developing these complications. By studying the size, number, and type of EVs, the team hopes to identify early markers that can guide doctors in providing better care. The study will collect cord blood from 30 eligible infants born at the CHU of Montpellier. Blood samples will be processed to isolate platelet-poor plasma, which contains EVs. This plasma will be stored in a biobank, allowing future research on EVs and their role in extreme prematurity. EVs will then be analyzed in the laboratory to assess their characteristics and any links to severe health issues. The findings from this study could improve understanding of circulatory problems in extremely premature infants, help identify early predictors of severe complications, and inform better monitoring and treatment strategies. The creation of a plasma biobank also provides a valuable resource for future research to enhance care and outcomes for this vulnerable population.

This is a drug study that will examine if inhaled tranexamic acid can improve mortality in patients with cancer-related pulmonary hemorrhage and respiratory failure as compared to usual care.
