FOB in HSCT and Leukemia Patients With Acute Respiratory Symptoms and Pulmonary Infiltrates
A Prospective Assessment of the Diagnostic Utility of Emerging Laboratory Assessments Used in Conjunction With FOB in HSCT and Leukemia Patients With Acute Respiratory Symptoms and Pulmonary Infiltrates
Pulmonary infiltrates frequently complicate the care of hematopoietic stem cell transplant (HSCT) and leukemia patients. Bronchoalveolar lavage (BAL) is frequently used to evaluate new pulmonary infiltrates in this population, however utility is limited by a historically low diagnostic yield for infection.
In an effort to improve diagnostic yields, this study will complete a Fiberoptic Bronchoscopy (FOB) within 8 hours of radiographic documentation of pulmonary infiltrates, prior to initiating new antibiotic therapy. To further improve detection of microbiological pathogens, the study will utilize PCR testing with rapid turnaround time to detect atypical pneumonia (M pneumoniae, C. Pneumonia, Legionella species, and respiratory viruses) and aspergillosis.
