We read with great interest the article by Kido et al 1 in an issue of CHEST (January 2012) demonstrating mucosa-associated lymphoid tissue (MALT) lymphoma translocation gene 1 rearrangements in BAL fl uid (BALF) in four of fi ve cases of pulmonary MALT lymphoma. The use of BALF is debated, but the authors elegantly demonstrate that BALF may be useful for the diagnosis of pulmonary disease, par...

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...

In chronic eosinophilic pneumonia (CEP), histopathological evidence exists for the degranulation of eosinophils and the release of various toxic proteins. In vitro studies have demonstrated the degranulation of eosinophils in response to aggregated and complexed immunoglobulins. The aims of this study were to investigate: 1) whether the eosinophil cationic protein (ECP) and immunoglobulin (Ig) ...

To clarify the interrelation between interleukin-2 (IL-2) and soluble IL-2R receptor (sIL-2R), as products of T-cell activation in the bronchial tree of patients with bronchial asthma, we measured the concentration of IL-2, sIL-2R, and the cellular composition in bronchoalveolar lavage (BAL) fluid. We also measured physiologic parameters, including provocation concentration of histamine require...

AIM The aim was to study the bronchoalveolar lavage (BAL) technique in evaluating the local immune response of pig immunized with Pasteurella multocida bacterin vaccine. MATERIALS AND METHODS Weaned piglets were immunized with formalin-inactivated P52 strain of P. multocida bacterin and evaluated for pulmonary immune response in BAL fluid. BAL was performed before vaccination and at different...

BACKGROUND Bronchoalveolar lavage (BAL) allows cell recovery from the lower respiratory tract; differential cell counts of BAL fluid gives important information in the assessment of various bronchial and pulmonary diseases. To the best of our knowledge no study has investigated the relation between the number of cells counted and the reproducibility of BAL fluid differential cell counts. OBJE...

We intratracheally administered lipopolysaccharide (LPS) to ICR mice and then collected BAL fluid and lung tissue to determine whether levels of neutrophils and/or myeloperoxidase (MPO) in bronchoalveolar lavage (BAL) fluid reflect lung tissue damage. Robust neutrophil accumulation into the alveolar space and lung tissue were almost completely abolished at seven days along with oxidative stress...

blood. Similar results in the pleural fluid have been reported by Groman et al;i however, in this report BAL cell analysis was not available. In our patients, the lymphocyte profile found in pkural effusion was closer to that seen in BAL. Lymphocyte subpopulation findings in the pleural fluid seem to be representative ofthe pleural histologic involvement, as BAL is of alveolitis. By contrast, i...

OBJECTIVES To determine the frequency of detection of Kaposi's sarcoma associated herpesvirus (KSHV), also known as human herpesvirus (HHV) type 8, DNA in bronchoalveolar lavage (BAL) fluid from HIV infected individuals with and without KS and to compare this with the detection rate in peripheral blood. Also to identify whether KSHV was associated with specific cell types in lavage fluid. MET...

It is unclear how cellular and soluble inflammatory markers in induced sputum relate to markers in lavage fluid and biopsies in chronic obstructive pulmonary disease (COPD). This was investigated and also the possible differences between subjects with COPD and healthy controls assessed. Eighteen nonatopic subjects with COPD and 11 healthy controls were studied. Sputum was induced by inhalation ...
