ClinConnect Summary
This clinical trial is studying how certain chemicals found in breath, known as volatile organic compounds (VOCs), can help doctors detect a serious fungal infection called invasive aspergillosis (IA) in patients who have received lung transplants. The researchers believe that measuring these compounds could provide a new way to diagnose this infection early, which is important for effective treatment.
To participate in the study, patients must be over 18 years old, have received a lung transplant, and be suspected of having an invasive fungal disease. They must also be able to provide breath samples and consent to join the trial. However, certain patients will not be eligible, such as those on mechanical ventilation or those who have been diagnosed with other respiratory infections recently. If you join, you will provide breath samples at appointments, and the study aims to see how well these samples can help identify IA. Your participation could contribute to better understanding and diagnosis of fungal infections in lung transplant recipients.
