BACKGROUND/AIMS Early diagnosis and appropriate antimicrobial choice are crucial when managing pneumonia patients, and quantitative culture of bronchoalveolar lavage (BAL) fluid is considered a useful method for identifying pneumonia pathogens. We evaluated the quantitative yield of BAL fluid bacterial cultures in patients being treated with antimicrobials and attempted to identify factors pred...
Although the application of thoracic high-resolution computed tomography (HRCT) to clinical pulmonology has revolutionised the diagnostic approach to patients with suspected interstitial lung disease (ILD), additional testing is often needed to make a confident ILD diagnosis. Bronchoalveolar lavage (BAL) can play a significant role in making an accurate and confident diagnosis of specific forms...
BACKGROUND Recent studies have revealed that bronchoalveolar lavage (BAL) fluid contains previously unappreciated communities of bacteria. In vitro and in vivo studies have shown that host inflammatory signals prompt bacteria to disperse from cell-associated biofilms and adopt a virulent free-living phenotype. The proportion of the lung microbiota that is cell-associated is unknown. RESULTS F...
BACKGROUND Tuberculosis (TB) causes 1.45 million deaths annually world wide, the majority of which occur in the developing world. Active TB disease represents immune failure to control latent infection from airborne spread. Acid-fast bacillus (AFB) seen on sputum smear is a biomarker for contagiousness. METHODS We enrolled 73 tuberculosis patients with extensive infiltrates into a research st...
The usefulness of bronchoalveolar lavage (BAL) fluid cellular analysis in non-human immunodeficiency virus (HIV)-infected patients with Pneumocystis jirovecii pneumonia (PCP) has not been adequately evaluated. The objective of this study was to analyze the cellular profiles of BAL fluid and to evaluate their prognostic significance in non-HIV-infected patients with PCP. A 7-year retrospective c...
It is unclear whether leukocytes in induced sputum (IS) and bronchoalveolar lavage (BAL) represent the same cell populations. To compare leukocyte counts and macrophage phenotypes and investigate any measurable dithiothreitol (DTT)-mediated effect on macrophage immunocytochemical staining results, IS and BAL samples from nine healthy smokers and seven nonsmokers were examined. BAL and IS sample...
OBJECTIVE Bronchoalveolar lavage (BAL) is a well established technique for the detection of pathogens in immunosuppressed children, but its diagnostic yield is variable. The aim of this study was to investigate whether BAL differential cell counts are helpful in the evaluation of pulmonary infiltrates in immunocompromised children. STUDY DESIGN BAL was performed 28 times in 27 febrile immunoc...
