title: Bronchoalveolar lavage as a diagnostic tool in patients with hematological malignancies and pneumonia.
abstract: We report our experience concerning bronchoalveolar lavage (BAL) in adult patients affected by haematological malignancies. BAL was performed in patients with documented pulmonary diseases not responding to empirical antibiotic and antifungal therapies. Overall, 25 bronchoscopies were performed in 24 patients. This technique led to pathogen identification in 11 out of 24 patients (45 percent). In particular, we identified four cases of tuberculosis, four of aspergillosis, two of pneumocystosis, two bacterial pneumonia and one pneumonia sustained by CMV (in two cases, pneumonia was polymicrobial). In three cases, where microbiological diagnosis had been obtained by means of other exams (blood culture, urinary antigens), BAL negativity allowed us to exclude alternative diagnoses. Pulmonary location of haematological disease was diagnosed in seven patients. BAL drove a switch therapy in 54 percent of patients. When performed by expert operators, BAL is useful and safe also in frail patients, such as those affected by onco-haematological malignancies.
