Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are patients diagnosed with acute leukemia who are undergoing chemotherapy and have neutropenia.

Probably not a fit

Patients who are unable to follow instructions for breath analysis or have anatomical abnormalities preventing the use of a mouthpiece will not benefit from this study.

What this trial studies

This study focuses on patients with leukemia who are at high risk for invasive fungal infections (IFI) due to chemotherapy-induced neutropenia. It aims to identify specific volatile biomarkers associated with IFI using secondary electrospray ionization high-resolution mass spectrometry (SESI-HRMS). The approach is non-invasive, which is crucial for patients who cannot undergo traditional diagnostic procedures due to severe thrombocytopenia. By analyzing breath samples, the study seeks to improve the accuracy of IFI diagnosis in this vulnerable population.

Why it matters

Potential benefit: If successful, this study could lead to a non-invasive method for early detection of invasive fungal infections in leukemia patients, potentially reducing morbidity and mortality.

How similar studies have gone: While the use of breath analysis for diagnostic purposes is an emerging field, this specific approach using SESI-HRMS for detecting fungal infections in leukemia patients is novel and has not been extensively tested in prior studies.
