BACKGROUND The clinical utility of bronchoalveolar lavage fluid (BAL) cell analysis for the diagnosis and management of patients with interstitial lung disease (ILD) has been a subject of debate and controversy. The American Thoracic Society (ATS) sponsored a committee of international experts to examine all relevant literature on BAL in ILD and provide recommendations concerning the use of BAL...
BACKGROUND Blood based Interferon-(IFN)-γ release assays (IGRAs) have a poor predictive value for the development of tuberculosis. This study aimed to investigate the correlation between IGRAs and pulmonary immune responses in tuberculosis contacts in Germany. METHODS IGRAs were performed on bronchoalveolar lavage (BAL) cells and peripheral blood from close healthy contacts of patients with c...
In the January 1991 issue of Chest, Baughman et al’ reported the utility of bronchoscopy with bronchoalveolar lavage (BAL) in the diagnosis of Mycobacterium tuberculosis infections, and they concluded that BAL is useful for this indication. However, the M tuberculosis infection was diagnosed with only BAL in one of 29 cases, when BAL and bronchial wash specimens were obtained together. In a pro...
The aim of this study was to investigate whether the demonstration of plasma cells (PC), which are normally absent in bronchoalveolar lavage (BAL) fluid, facilitates differentiation among pulmonary disorders. Initial BAL fluid samples of 1,260 patients were analyzed. In 83 of these, PC were found. Of these 83, 47 were obtained from individuals suffering from extrinsic allergic alveolitis (EAA)....
OBJECTIVE To assess the diagnostic yield of fibreoptic bronchoscopy and bronchoalveolar lavage (BAL) compared to gastric aspiration (GA) in children with probable pulmonary tuberculosis (TB). METHODS Children with probable pulmonary TB were subjected to bronchoscopy, BAL and gastric aspiration. The samples were examined for acid fast bacilli (AFB) on smear. RESULTS A total of 52 children un...
Although neutrophil number may be increased in the airways of patients with asthma, its pathogenetic role in this disorder remains unclear. We evaluated BAL of 8 normal control subjects, 30 +/- 2 years of age, and 24 patients with mild asthma: 17 patients with allergic asthma, 24 +/- 1 years of age, and 7 patients with nonallergic asthma, 30 +/- 1 years of age. The BAL of asthmatic patients sho...
It is known that cAMP and cGMP are important for vasorelaxation, and cyclic nucleotide phosphodiesterases (PDEs) regulate their levels. Balloon angioplasty (BAL) is associated with reduced cAMP and cGMP levels, and inhibition of PDE-3 reduces restenosis. In this study, we found that BAL increased PDE-3 activity, which affected vasoreactivity of rat aortic rings 24-h post-BAL; these were compare...
