BACKGROUND Hepatitis C virus (HCV) infection has recently been incriminated as an aetiological agent in idiopathic pulmonary fibrosis. This study was performed to determine the cellularity and lymphocyte phenotypes of bronchoalveolar lavage (BAL) fluid in patients with chronic hepatitis C. METHODS BAL fluid and lavage lymphocyte subsets from 13 patients (10 men) with active chronic hepatitis ...
Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus s...
Airway neuropeptides, in particular calcitonin gene-related peptide (CGRP), are likely to be important in the pathogenesis of chronic cough. The present authors evaluated the following: 1) the relationship between cough sensitivity and bronchoalveolar lavage (BAL) neuropeptides; and 2) the effect of reflux oesophagitis (RO) on cough, cough sensitivity and BAL neuropeptides in children not selec...
Ribeiro V.M., Barçante J.M.P., Negrão-Correa D., Barçante T.A., Klein A. & Lima W.S. 2014. Bronchoalveolar lavage as a tool for evaluation of cellular alteration during Aelurostrongylus abstrusus infection in cats. Pesquisa Veterinária Brasileira 34(10):990995.

BACKGROUND Bronchoalveolar lavage (BAL) has been widely accepted as a routine procedure in the differential diagnosis of respiratory diseases in adults. However, there is only limited information about the value of BAL in children and there is no standardisation of the procedures. METHODS The difference in cellular profiles of sequential BAL fractions from children was analysed to assess the ...
Objective: Bronchoalveolar lavage (BAL) fluid provides a crucial tool for investigation of the cellular component of the deep lung spaces and hence to approach the alloreactive response following lung transplantation. This study investigated whether BAL cell profiles can assist for the diagnosis of certain postoperative complications. Methods: We conducted a retrospective analysis of both trans...
BACKGROUND This study was designed to determine the accuracy of bronchoalveolar lavage fluid cytology (BAL) using histopathologic examination of transbronchial biopsy specimens as the gold standard in diagnosis of lung carcinoma at our center. MATERIALS AND METHODS A retrospective study was conducted to investigate a total of 388 patients who were suspected of having lung cancer and had under...
We have investigated the level of lymphocytosis present in the lung of human immunodeficiency virus (HIV)-1+ infected patients with and without pulmonary disease and how changes in natural killer (NK), B and T-cells seen in peripheral blood (PB) compare with those seen in bronchoalveolar lavage fluid (BALF). Lymphocyte subpopulations and their expression of activation, cytotoxic markers and mem...
Macrophages, neutrophils and infection have been implicated in the genesis of the bronchiolitis obliterans syndrome (BOS) post lung transplantation. sCD14 is a soluble form of a shed-cell surface protein. It is capable of promoting cytokine-induced inflammation and it's presence in clinically stable lung transplant recipients (LTR) might be important as an early marker of BOS. Bronchalveolar la...
Methacholine (MCh) challenge testing is often incorporated into clinical studies prior to performing bronchoscopy as a measure of bronchial hyperresponsiveness (BHR). However, the effect of methacholine on many aspects of bronchoalveolar lavage (BAL) fluid cell count and function have not been fully evaluated. Ten patients with asthma, maintained on inhaled beta 2-agonists, were studied. Each s...
