To investigate the safety of repeated bronchoalveolar lavage (BAL) and the variability of commonly measured parameters from BAL to BAL in the same subject, we performed a total of 59 BALs in 16 normal volunteer subjects. The BAL was performed with 120 ml (three aliquots of 40 ml) of room temperature, normal saline in a lingular subsegment. Four subjects had five BAL, three had four BAL, and nin...

background and purpose: invasive aspergillosis (ia) is one of the most common life-threatening fungal infections among the critically ill patients including intensive care unit (icu) patients. delayed diagnosis and therapy may lead to poor outcomes. diagnosis may be facilitated by a test for molecular biomarkers, i.e. detection of galactomannan (gm) antigen based on enzyme immunoassay, which is...

objective: among the members of legionellaceae, legionella pneumophila is involved in 95% of cases of severe pneumonia. isolation of the causative agent from bronchoalveolar lavage (bal) fluid specimen is a delicate process and also time-consuming. moreover, it has been shown that some legionella strains may be viable but cannot be cultured. the aim of this study was comparison of culture and p...

Bronchoalveolar lavage fluid from 43 patients with biopsy proved sarcoidosis and 10 control subjects were assayed for fibronectin and collagenase activity. Fibronectin was significantly increased in the group with sarcoidosis and was found to be positively correlated with angiotensin converting enzyme activity, protein concentration, percentage of T cells and helper:suppressor ratios in the lav...

OBJECTIVE To test the hypothesis that total liquid ventilation enables a more effective and better tolerated lavage than a bronchoalveolar lavage performed with diluted surfactant in a newborn ovine model of severe acute meconium aspiration syndrome. DESIGN Prospective, randomized, interventional study. SETTING Animal research laboratory at the Faculté de médecine et des sciences de la sant...

BACKGROUND Bronchial mucosal inflammation and epithelial damage are characteristic features of asthma. Activation of T helper lymphocytes may contribute to this process by mechanisms including the release of cytokines promoting eosinophil infiltration and activation. METHODS Bronchial washings and bronchoalveolar lavage fluid were obtained from 29 atopic asthmatic patients (19 with current sy...
