About this study
Pulmonary hemorrhage can be severe and life-threatening. In children, etiologies of pulmonary hemorrhage include respiratory infection, foreign bodies, bronchiectasis, pulmonary vascular disorders, parenchymal lung disease, and post-surgical complications. Initial management of pulmonary hemorrhage includes stabilization of the patient, securing the airway, initiative high positive end-expiratory pressure to attempt to tamponade the source of hemorrhage and repletion with blood products. Following stabilization of the patient, investigation and further management of hemorrhage includes bronchoscopy, surgery, or catheterization. Sources of bleeding such as endobronchial lesions are often identified and managed with bronchoscopy and the instillation of vasoactive medications or cold water to induce vasospasm and/or balloon tamponade. Vascular bleeding can be surgically ligated or embolized via catheterization. Unidentifiable bleeding occurs with distal vascular injury and is limited to attempted catheter guided embolization of bleeding vessels if found, supportive treatment, and correction of a coagulopathy if present. As etiologies of pulmonary hemorrhage vary, outcomes and prognosis in pediatric pulmonary hemorrhage are difficult to determine, however, mortality still remains a risk.
Tranexamic acid (TXA) is a lysine analog that blocks the conversion of plasminogen to plasmin and the interaction with fibrin, preventing blood clot breakdown, thereby reducing bleeding. The United States (US) Food and Drug Administration approved the intravenous formulation of TXA for the treatment of bleeding patients with hemophilia in 1986 and the oral formulation for the use of severe menorrhagia in 2009. In 2011, The World Health Organization listed TXA as an essential medication based on its successful use in adult trauma-related hemorrhage. Studies show the successful off-label use of TXA in children for congenital heart surgery, orthopedic procedures, neurosurgical procedures, trauma, immune thrombocytopenic purpura, epistaxis, hemorrhage complicating a procedure, bilateral lung transplantation, chemotherapy injections, and bone marrow biopsies among other diagnoses and procedures. Very little data on the use of TXA for pediatric pulmonary hemorrhage exists. Only two case reports show TXA controlling hemoptysis in children with cystic fibrosis-related hemoptysis. A systematic review concluded that the use of TXA for hemoptysis was associated with a significant reduction in length of bleeding. A recent randomized control trial showed the TXA decreased the severity of the hemoptysis and may be used as a bridge to other interventions.
The powerful anti-fibrinolytic properties and relatively low side-effect profile lend TXA to the off-label use in children to reduce bleeding in other diagnoses. There are not enough studies and data, however, to recommend the routine use of TXA in hemoptysis.

Questions about this trial
What is this clinical trial studying?
An observational study of Pulmonary Hemorrhage and MAPCA - Major Aortopulmonary Collateral Artery, run by Baylor College of Medicine at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
resolution of pulmonary hemorrhage (time frame: 5 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Aug 2020.
