“…In these patients, reported diagnostic yields range from 35 to 60%. 8,9,11,12,15,17,[18][19][20][21][22][23][24] We found comparable results in our patients with lymphoid malignancies, with a diagnostic yield of 50%. The much lower diagnostic yield of FOB-BAL in our AML patients with ARF admitted in ICU raises several issues, dominated by the differences in studied populations between available reports.…”

“…Accordingly, FOB-BAL yield was lower in our neutropenic than in nonneutropenic patients: 11 vs 36%. Conversely, no such difference was found in a large study by Cordonnier et al 18 However, it should be noticed that this study was not performed in ICU patients, although the number of patients who did not receive antibiotics was higher than in our study. Third, the prolonged neutropenia observed in AML patients leads to a higher incidence of pulmonary aspergillosis than in previous studies.…”

Is BAL useful in patients with acute myeloid leukemia admitted in ICU for severe respiratory complications?

In patients with hematological malignancy (HM) developing acute respiratory failure (ARF) bronchoalveolar lavage (BAL) is considered as a major diagnostic tool. However, the benefit/risk ratio of this invasive procedure is probably lower in the subset of patients with acute myeloid leukemia (AML). The study was to analyze the yield of BAL performed in HM patients (n ¼ 175) with AML or lymphoid malignancies (LM) admitted in intensive care unit (ICU) for ARF and pulmonary infiltrates. BAL was performed in 121 patients (53/73 AML patients (73%) and 68/102 LM patients (67%)) without a definite diagnosis at admission or contraindication for fiberoptic bronchoscopy. Life-threatening complications were noticed in 12/121 patients (10%). The overall diagnostic yield of BAL was 47% (25/53) in AML patients and 50% (34/68) in LM patients. A microorganism was recovered from BAL in 23% (12/53) of AML patients and 41% (28/68) of LM patients (Po0.005). BAL results induced significant therapeutic changes in 17% (9/53) of AML patients vs 35% (24/68) of LM patients (P ¼ 0.039). This study underlines the rather low diagnostic yield of BAL for infectious diagnosis and the low rate of therapeutic changes induced by its results in AML patients with ARF admitted in ICU.

Summary:Invasive pulmonary aspergillosis (IPA) is a life-threatening infectious complication in neutropenic patients after high-dose chemotherapy or hematopoietic stem cell transplantation. Its diagnosis is mainly based on clinical symptoms, and radiological signs on thoracic CT scan. The value of bronchoscopy is controversial. We analyzed the diagnostic yield of bronchoscopy in 23 consecutive patients with histologically proven invasive pulmonary aspergillosis. In seven patients (30%) bronchoscopically obtained specimens were diagnostic for pulmonary fungal infection. Typical hyphae were detected by cytology in six patients and fungal cultures were positive in four cases. Patients with a positive bronchoscopic result presented more often with multiple changes on thoracic CT scan (71%; 5/7), but had received a lower median cumulative dose of amphotericine B (300 mg; 168-3010 mg) compared to patients with non-diagnostic bronchoscopy (25% multiple lesions (4/16); amphotericine dose 1100 mg, 260-2860 mg). The diagnostic yield of bronchoscopy was not associated with clinical symptoms or duration of neutropenia. Bronchoscopy allows the diagnosis of IPA in about one third of patients. Fungal cultures and cytological examination of intrabronchial specimens obtained during bronchoscopy have a high specificity, but its sensitivity is low. It is advisable to perform diagnostic bronchoscopy before starting antifungal therapy. Better diagnostic tools are urgently needed.
