Özet
Background: Pneumonia is a major cause of morbidity and mortality in immunocompromised patients. Bronchoalveolar lavage (BAL) is commonly used to help diagnose and characterize pneumonia in these patients. Mini-BAL is a less-invasive, less-costly and less-cumbersome diagnostic tool than BAL. Objectives: In this study, we compared the diagnostic value of BAL and mini-BAL in the evaluation of pneumonia in immunocompromised patients with respiratory failure. Methods: Sixty-four respiratory samples were collected from 32 immunocompromised patients admitted to our respiratory intensive care unit with a clinical diagnosis of pneumonia and respiratory failure requiring invasive mechanical ventilation. A single BAL sample and a single mini-BAL sample were collected from each patient. Samples were examined for bacteriologic, mycologic, mycobacteriologic, and viral organisms. Results: The mean age of the patients was 56.0 +/- 14.4 years. Of the 32 BAL samples, bacterial isolates were detected in 11 patients (34.4%) and on the other hand bacterial isolates were detected in 10 patients (31.3%) of the mini-BAL samples. Fungal isolates were detected in 11 patients (34.4%) from BAL samples and 13 patients (40.6%) from mini-BAL samples. Our analysis demonstrated a strong positive correlation between the results of BAL and mini-BAL testing (r = 0.850 and r = 0.821, respectively). Conclusion: In this study, we demonstrated a strong correlation between the isolation rates of bacteria and fungi in BAL and mini-BAL samples obtained from immunocompromised patients with pneumonia and respiratory failure. The data strongly support the use of mini-BAL sampling in such patients as a less-invasive, less-costly and simpler alternative to traditional BAL. Copyright (C) 2011 S. Karger AG, Basel
