| Popis: | Pulmonary complications in children with leukemia often display nonspecific clinical and radiologic manifestations that lead to a delay in diagnosis. The role of fiberoptic bronchoscopy (FOB) and the proper time for its performance are controversial. The aim of our study was to evaluate the frequency and nature of specific diagnoses revealed by FOB. Children with leukemia submitted to FOB because of suspicion of pulmonary involvement (mainly pneumonia) were retrospectively analyzed. A total of 33 FOB procedures performed in 31 patients (20 males) with an average age of 9.4 years (range, 3.5 to 15 y) were evaluated. Microorganisms isolated from 21 (63.6%) bronchoalveolar lavage samples were mainly fungi including Candida in 13 cases (39.4%) and Aspergillus in 3 cases (9.1%). Isolation rate in 10 procedures performed within the first 3 days was 90%. Tracheobronchitis was present in > 50% of patients, pulmonary hemorrhage was seen in 7 (21.0%) patients, and leukemic infiltration was demonstrated in 2 patients (6.1%), among other conditions visualized by FOB. Complications of FOB were minimal and transient. Our study suggests that FOB is a useful and safe procedure in patients with leukemia and pulmonary infiltrates. The earlier the FOB was performed, the higher the isolation rate of causative agents. In addition, this procedure allowed the identification of noninfectious airway comorbidities. Further studies in regard to this issue are warranted. |
