GM-CSF-deficient mice are susceptible to pulmonary group B streptococcal infection. (1/5496)

Granulocyte-macrophage colony-stimulating factor (GM-CSF) gene-targeted mice (GM-/-) cleared group B streptococcus (GBS) from the lungs more slowly than wild-type mice. Expression of GM-CSF in the respiratory epithelium of GM-/- mice improved bacterial clearance to levels greater than that in wild-type GM+/+ mice. Acute aerosolization of GM-CSF to GM+/+ mice significantly enhanced clearance of GBS at 24 hours. GBS infection was associated with increased neutrophilic infiltration in lungs of GM-/- mice, while macrophage infiltrates predominated in wild-type mice, suggesting an abnormality in macrophage clearance of bacteria in the absence of GM-CSF. While phagocytosis of GBS was unaltered, production of superoxide radicals and hydrogen peroxide was markedly deficient in macrophages from GM-/- mice. Lipid peroxidation, assessed by measuring the isoprostane 8-iso-PGF2alpha, was decreased in the lungs of GM-/- mice. GM-CSF plays an important role in GBS clearance in vivo, mediated in part by its role in enhancing superoxide and hydrogen peroxide production and bacterial killing by alveolar macrophages.  (+info)

Molecular detection of tumor cells in bronchoalveolar lavage fluid from patients with early stage lung cancer. (2/5496)

BACKGROUND: Conventional cytologic analysis of sputum is an insensitive test for the diagnosis of non-small-cell lung cancer (NSCLC). We have recently demonstrated that polymerase chain reaction (PCR)-based molecular methods are more sensitive than cytologic analysis in diagnosing bladder cancer. In this study, we examined whether molecular assays could identify cancer cells in bronchoalveolar lavage (BAL) fluid. METHODS: Tumor-specific oncogene mutations, CpG-island methylation status, and microsatellite alterations in the DNA of cells in BAL fluid from 50 consecutive patients with resectable (stages I through IIIa) NSCLC were assessed by use of four PCR-based techniques. RESULTS: Of 50 tumors, 28 contained a p53 mutation, and the identical mutation was detected with a plaque hybridization assay in the BAL fluid of 39% (11 of 28) of the corresponding patients. Eight of 19 adenocarcinomas contained a K-ras mutation, and the identical mutation was detected with a mutation ligation assay in the BAL fluid of 50% (four of eight) of the corresponding patients. The p16 gene was methylated in 19 of 50 tumors, and methylated p16 alleles were detected in the BAL fluid of 63% (12 of 19) of the corresponding patients. Microsatellite instability in at least one marker was detected with a panel of 15 markers frequently altered in NSCLC in 23 of 50 tumors; the identical alteration was detected in the BAL fluid of 14% (three of 22) of the corresponding patients. When all four techniques were used, mutations or microsatellite instability was detected in the paired BAL fluid of 23 (53%) of the 43 patients with tumors carrying a genetic alteration. CONCLUSION: Although still limited by sensitivity, molecular diagnostic strategies can detect the presence of neoplastic cells in the proximal airway of patients with surgically resectable NSCLC.  (+info)

Localization of a candidate surfactant convertase to type II cells, macrophages, and surfactant subfractions. (3/5496)

Pulmonary surfactant exists in the alveolus in several distinct subtypes that differ in their morphology, composition, and surface activity. Experiments by others have implicated a serine hydrolase in the production of the inactive small vesicular subtype of surfactant (N. J. Gross and R. M. Schultz. Biochim. Biophys. Acta 1044: 222-230, 1990). Our laboratory recently identified this enzyme in the rat as the serine carboxylesterase ES-2 [F. Barr, H. Clark, and S. Hawgood. Am. J. Physiol. 274 (Lung Cell. Mol. Physiol. 18): L404-L410, 1998]. In the present study, we determined the cellular sites of expression of ES-2 in rat lung using a digoxygenin-labeled ES-2 riboprobe. ES-2 mRNA was localized to type II cells and alveolar macrophages but not to Clara cells. Using a specific ES-2 antibody, we determined the protein distribution of ES-2 in the lung by immunohistochemistry, and it was found to be consistent with the sites of mRNA expression. Most of the ES-2 in rat bronchoalveolar lavage is in the surfactant-depleted supernatant, but ES-2 was also consistently localized to the small vesicular surfactant subfraction presumed to form as a consequence of conversion activity. These results are consistent with a role for endogenous lung ES-2 in surfactant metabolism.  (+info)

Expression of heat shock protein 72 by alveolar macrophages in hypersensitivity pneumonitis. (4/5496)

The current study was done to look at a possible role of heat shock proteins (HSPs) in hypersensitivity pneumonitis (HP). The specific aims were to determine whether there was a difference in the expression of HSP72 in alveolar macrophages (AMs) between mice challenged with HP antigen and saline-treated control mice and between AMs obtained by bronchoalveolar lavage from 18 patients with HP and 11 normal subjects. The expression of HSP72 was studied under basal conditions and under a mild heat shock. HSP72 expression by AMs in response to in vitro stimulation with Saccharopolyspora rectivirgula was lower in AMs of control mice than in those of HP animals. HSP72 was constitutively expressed in AMs of both normal and HP subjects. Densitometric ratios showed that AMs from normal subjects responded to heat shock with a 39 degrees C-to-37 degrees C ratio of 1.72 +/- 0.18 (mean +/- SE), and AMs from HP patients responded with a ratio of 1.16 +/- 0.16 (P = 0.0377). This decreased induction by additional stress of AMs could lead to an altered immunoregulatory activity and account for the inflammation seen in HP.  (+info)

A rapid polymerase chain reaction technique for detecting M tuberculosis in a variety of clinical specimens. (5/5496)

A rapid in-house polymerase chain reaction (PCR) assay is described for the direct detection of Mycobacterium tuberculosis complex in clinical material. Its performance is compared with two kit based systems. The results of the in-house assay were comparable with the commercial assays, detecting M tuberculosis in 100% of smear positive, culture positive samples. The in-house assay proved to be rapid, easy, and inexpensive to perform, and the inclusion of an internal inhibitor control permitted validation of the PCR results.  (+info)

Cigarette smoking decreases interleukin-8 secretion by human alveolar macrophages. (6/5496)

Cigarette smoking can impair pulmonary immune function, and hence influences the development of lung diseases. Interleukin-8 (IL-8) is a proinflammatory peptide and a potent chemotactic factor for neutrophils, and is produced by both immune and non-immune cells including monocytes and alveolar macrophages (AM). We investigated the effect of cigarette smoking on the secretion of IL-8 by human AM. The IL-8 concentration in bronchoalveolar lavage fluid (BALF) was much higher in smokers than in non-smokers (18.4 +/- 3.9 vs 4.1 +/- 1.0 pg ml-1; P < 0.005). However, spontaneous IL-8 secretion by cultured AM was lower in smokers than in non-smokers (46.8 +/- 12.7 vs 124.1 +/- 24.0 ng ml-1; P < 0.01). When stimulated with lipopolysaccharide (LPS), AM from smokers secreted significantly less IL-8 than those from non-smokers at all tested concentrations of LPS. In contrast, the amount of IL-8 secreted by peripheral blood monocytes with or without LPS stimulation was comparable in smokers and non-smokers. These observations indicate that smoking decreases IL-8 secretion by AM, which may modify or decrease the inflammatory response in the lung.  (+info)

Effect of hyperoxia on human macrophage cytokine response. (7/5496)

In the development of lung damage induced by oxidative stress, it has been proposed that changes in alveolar macrophages (AM) function with modifications in cytokine production may contribute to altered repair processes. To characterize the changes in profiles of cytokine production by macrophages exposed to oxidants, the effects of hyperoxia (95% O2) on interleukin (IL)-1 beta, IL-6, IL-8, and tumour necrosis factor-alpha (TNF-alpha) expression were studied. Experiments were first performed using AM obtained from control subjects and children with interstitial lung disease. Results showed that a 48 h O2 exposure was associated with two distinct patterns of response: a decrease in TNF-alpha, IL-1 beta and IL-6 expression, and an increase in IL-8. To complete these observations we used U937 cells that were exposed for various durations to hyperoxia. We confirmed that a 48 h O2 exposure led to similar changes with a decrease in TNF-alpha, IL-1 beta and IL-6 production and an increase in IL-8. Interestingly, this cytokine response was preceded during the first hours of O2 treatment by induction of TNF-alpha, IL-1 beta and IL-6. These data indicate that hyperoxia induces changes in the expression of macrophages inflammatory cytokines, and that these modifications appear to be influenced by the duration of O2 exposure.  (+info)

Pneumonia in febrile neutropenic patients and in bone marrow and blood stem-cell transplant recipients: use of high-resolution computed tomography. (8/5496)

PURPOSE: To obtain statistical data on the use of high-resolution computed tomography (HRCT) for early detection of pneumonia in febrile neutropenic patients with unknown focus of infection. MATERIALS AND METHODS: One hundred eighty-eight HRCT studies were performed prospectively in 112 neutropenic patients with fever of unknown origin persisting for more than 48 hours despite empiric antibiotic treatment. Fifty-four of these studies were performed in transplant recipients. All patients had normal chest roentgenograms. If pneumonia was detected by HRCT, guided bronchoalveolar lavage was recommended. Evidence of pneumonia on chest roentgenograms during follow-up and micro-organisms detected during follow-up were regarded as documentation of pneumonia. RESULTS: Of the 188 HRCT studies, 112 (60%) showed pneumonia and 76 were normal. Documentation of pneumonia was possible in 61 cases by chest roentgenography or micro-organism detection (54%) (P < 10(-6)). Sensitivity of HRCT was 87% (88% in transplant recipients), specificity was 57% (67%), and the negative predictive value was 88% (97%). A time gain of 5 days was achieved by the additional use of HRCT compared to an exclusive use of chest roentgenography. CONCLUSION: The high frequency of inflammatory pulmonary disease after a suspicious HRCT scan (> 50%) proves that pneumonia is not excluded by a normal chest roentgenogram. Given the significantly longer duration of febrile episodes in transplant recipients, HRCT findings are particularly relevant in this subgroup. Patients with normal HRCT scans, particularly transplant recipients, have a low risk of pneumonia during follow-up. All neutropenic patients with fever of unknown origin and normal chest roentgenograms should undergo HRCT.  (+info)

The objective of this study was to review the literature on bronchoalveolar lavage fluid cell profiles in healthy children and adolescents, as well as on the use of BAL as a diagnostic and follow-up tool for lung disease patients in this age bracket. To that end, we used the Medline database, compiling studies published between 1989 and 2009 employing the following MeSH descriptors (with Boolean operators) as search terms: bronchoalveolar lavage AND cytology OR cell AND child. In healthy children, the cell profile includes alveolar macrophages (> 80%), lymphocytes (approximately 10%), neutrophils (approximately 2%) and eosinophils (< 1%). The profile varies depending on the disease under study. The number of neutrophils is greater in wheezing children, especially in non-atopic children, as well as in those with pulmonary infectious and inflammatory profiles, including cystic fibrosis and interstitial lung disease. Eosinophil counts are elevated in children/adolescents with asthma and can reach ...

N2 - Acute respiratory distress syndrome (ARDS) is characterized by a disruption of the alveolar-capillary barrier, due to both an epithelial and an endothelial dysfunction. Whereas epithelial apoptosis seems to be mainly mediated by Fas ligand, the mediators of endothelial damage remain to be identified. Angiostatin, a powerful inhibitor of angiogenesis in vivo, also specifically induces apoptosis in endothelial cells. The concentration of various enzymes that cleave angiostatin from plasminogen was reported to be significantly increased in bronchalveolar lavage (BAL) fluids from patients with ARDS. Therefore, in this study, we ...

The usefulness of bronchoalveolar lavage in the diagnosis of pulmonary infiltrates in the immunosuppressed patient was studied in 97 patients. In immunosuppressed patients, the available diagnostic procedures are often invasive and have variable yield and a potential for serious complications. Bronchoalveolar lavage had an overall diagnostic yield of 66% (61 of 92 diseases). It was most effective in the diagnosis of opportunistic infections, including infection with Pneumocystis carinii (18 of 22 cases), cytomegalovirus pneumonia (10 of 12 cases), fungal pneumonia (5 of 6 cases), and mycobacterial disease (4 of 5 cases). The technique was also helpful in confirming pulmonary hemorrhage (7 of 9 cases) but was less useful for diagnosing malignancy (10 of 22 cases) and drug-induced toxicity (6 of 15 cases). Findings of bronchoalveolar lavage were additive with those of transbronchial biopsies, brushings, and washings in the diagnosis of most of the diseases. The procedure was safe, even in ...
en] An increased production of NO* and peroxynitrite in lungs has been suspected during acute lung injury (ALI) in humans, and recent studies provided evidence for an alveolar production of nitrated compounds. We observed increased concentrations of nitrites/nitrates, nitrated proteins and markers of neutrophil degranulation (myeloperoxidase, elastase and lactoferrine) in the fluids recovered from bronchoalveolar lavage fluids (BALF) of patients with ALI and correlated these changes to the number of neutrophils and the severity of the ALI. We also observed that BALFs stimulated the DNA-binding activity of the nuclear transcription factor kappa B (NF-kappaB) as detected by electrophoretic mobility shift assay in human alveolar cells (A549) and monocytes (THP1). The level of activation of the NF-kappaB-binding activity was correlated to the concentration of nitrated proteins and myeloperoxidase. Furthermore, in vitro studies confirmed that NO*-derived species (peroxynitrite and nitrites) and the ...
Several components of cellular and humoral immunity were examined in bronchoalveolar lavage fluid and blood of 15 patients with the acquired immunodeficiency syndrome, and the results were compared to data from 25 healthy controls (including 5 asymptomatic homosexual men). Compared with that of controls, bronchoalveolar lavage fluid from patients tended to have more lymphocytes and significantly more neutrophils; a lower OKT4/OKT8 ratio, due to an increase in total OKT8 cells; and normal total OKT4 cell counts, despite a significant decrease in numbers of OKT4 cells in peripheral blood. Patients also had significantly more IgG-releasing cells and higher IgG levels than controls in lavage fluid. These data show that, in the lung lining fluid of patients with the acquired immunodeficiency syndrome, significant alterations in cellular and humoral immunity exist that differ in several important respects from immunity in controls and from corresponding changes in patients peripheral blood. ...

N2 - Patients with asthma generate increased amounts of reactive oxygen species (ROS) from peripheral blood cells and cells recovered by bronchoalveolar lavage (BAL). ROS produce many of the pathophysiologic changes associated with asthma and may contribute to its pathogenesis. Although antioxidant defenses inhibit the changes produced by ROS, no data are available on local antioxidant defenses in asthma. The present study was designed to begin to explore these defenses by measuring superoxide dismutase (SOD) and catalase activities and total glutathione (GSH) levels in BAL fluid from normal subjects and patients with mild asthma. Baseline pulmonary function and methacholine bronchoprovocation tests were performed on all subjects. BAL was achieved by instilling five 20-ml aliquots of phosphate-buffered saline in ...
Background: Cytologic examination of specimens obtained from the respiratory tract is a lung cancer diagnostic procedure with high specificity, but moderate sensitivity. The use of molecular biomarkers may enhance the sensitivity of cytologic examination in the detection of lung cancer. Methods: Complement factor H, a protein secreted by lung cancer cells, was quantified in a series of bronchoalveolar lavage supernatants from lung cancer patients and patients with non-malignant respiratory diseases. Albumin, total protein content, and hemoglobin were also analyzed. Results were validated in independent sets of bronchoalveolar lavage and sputum supernatants. Results: There was a significantly higher concentration of factor H in bronchoalveolar lavage samples from lung cancer patients. The sensitivity and specificity of the factor H test was 82% and 77%, respectively. These results were validated in an independent set of patients with nearly identical results. Furthermore, 70% and 45% of ...
The purpose of this study is to explore the correlations of interleukin 36 (IL-36) and Soluble B7-H3 (sB7-H3) levels in bronchoalveolar lavage fluid (BALF) with clinical characteristics and laboratory findings. A total of 35 children with M. pneumnoiae pneumonia (MPP) and 15 control subjects were enrolled. BALF concentrations of sB7-H3 and IL-36 were detected using enzyme-linked immunosorbent assays and clinical profiles of children with MPP were obtained. Children with MPP had significantly higher levels of sB7-H3 and IL-36 compared to control subjects (both P < 0.05). Meanwhile, children with pleural effusion had significantly higher levels of sB7-H3 and IL-36 compared to children without pleural effusion (both P < 0.05). BALF concentration of sB7-H3 was strongly associated with concentration of IL-36 (r = 0.796, P < 0.0001) and sB7-H3 was correlated with duration of fever (r = 0.427, P = 0.11) and length of stay (r = 0.345, P = 0.043). Both concentrations of sB7-H3 and IL-36 were significantly

In this study we have analysed the phenotype of CD4+ and CD8+ T lymphocytes from PBL and BAL fluid, as well as peripheral blood monocytes and alveolar macrophages from patients with sarcoidosis. Cells were studied with respect to expression of various surface activation markers, co-stimulatory and adhesion molecules. In addition, we investigated differences between cells from patients with active and inactive disease.. Our results highlight the role of T cells in sarcoidosis as there was an increased expression by BAL lymphocytes of several of the molecules studied-for example, CD26, CD95 (Fas), and the activation markers CD69 and gp240. This is in agreement with previous studies investigating other activation markers such as IL-2R (CD25), very late activation antigen-1 (VLA-1), CD49a, CD49d, and HLA-DR.11-14 A role for the receptor-ligand adhesion molecule pair CD11a/CD18-CD54 is indicated by our demonstration of increased expression of CD11a on alveolar macrophages as well as on peripheral ...

The pathophysiological role of inflammation in lung diseases including asthma and chronic obstructive pulmonary disease is well established. Quantifying lung inflammation is relevant for the management of inflammatory airway diseases as it may indicate that pharmacological intervention is required before symptom onset and reduction in lung function. Moreover, monitoring of airway inflammation might be useful in the follow-up of patients with asthma and COPD, and for guiding pharmacological therapy. Quantification of pulmonary inflammation is currently based more on invasive methods including the analysis of broncho-alveolar lavage fluid, bronchoscopy, and bronchial biopsies, semi-invasive methods such as sputum induction, and the measurement of inflammatory biomarkers in plasma and urine, which are likely to reflect systemic rather than lung inflammation. Interest in the identification of non-invasive biomarkers for inflammatory airway diseases has been growing. Along these years less invasive ...
Pulmonary infection is normally a major reason behind mortality and morbidity as well as the magnitude from the lung inflammatory response correlates with affected person survival. and peptidoglycan (PGN) implemented intratracheally significantly elevated the amounts of neutrophils retrieved in the bronchoalveolar lavage liquid (BALF). F344 got approximately 10-flip even more neutrophils in the BALF weighed against DA (< 0.001) and higher BALF concentrations of total proteins tumor necrosis aspect-α and macrophage inflammatory proteins 2. LTA/PGN administration in DA×F344 congenic strains (with LTA/PGN created significantly higher degrees of keratinocyte-derived chemokine and macrophage inflammatory proteins 2 than alveolar macrophages from DA rats. The distinctions had been linked to differential mitogen-activated proteins kinase phosphorylation. We conclude the fact that factors adding to irritation could be site and problem dependent. A better knowledge of site-specific irritation can lead ...
Airborne Fe2O3 nanoparticles (NPs) with the mean diameter of 14 4 nm produced at spark ablation from 99.99% pure iron rods were fed into a nose-only exposure tower for rats exposed for 4 h a day, 5 days a week during 3, 6 or 10 months at a mean concentration of 1.14 0.01 mg/m3. Nanoparticles filtered out of the air exhausted from the exposure tower proved insoluble in de-ionized water but gradually dissolved in the cell free fluid supernatant produced by broncho-alveolar lavage and in the sterile bovine blood serum. The Fe2O3 content in lungs was measured by the Electron Paramagnetic Resonance (EPR) spectroscopy. NP retention in lungs and in brain was visualized with the Transmission Electron Microscopy (TEM). It was found a relatively low but significant pulmonary accumulation of Fe2O3, gradually increasing with time but tending to attain an equilibrium level. Besides, TEM-images showed nanoparticles retention within alveolocytes and the myelin sheaths of brain fibers associated with their ...

The paper is concerned with the description of clinical, x-ray and morphological investigation of 123 bronchoalveolar cancer patients. Three types of this disease were defined: nodular (homogeneous and nonhomogeneous), pneumonia-like (infiltrative and infiltrative-nodular) and mixed (focal-disseminated, focal-nodular and focal-infiltrative). These types of bronchoalveolar cancer are most probably stages of the same tumor process. Clinical and x-ray signs of each type showed correlation with a morphological picture of a tumor. Shadow nonhomogeneity as one of the main x-ray signs of bronchoalveolar cancer was shown to be determined by the alveolar structure of a tumor, a tendency to the formation of small cavities, filled with viscous mucosa and air. Correct clinical and x-ray diagnosis in all types of bronchoalveolar cancer (before the use of the morphological methods) was established in 45.5% of the patients ...

Through activation via their FcεRII receptors or by acting as antigen-presenting cells, macrophages could, in theory, promote the late airway response to allergen. Objective: In order to investigate the importance of macrophages and other airway luminal cells in inducing the late airway response, a novel washout experiment was designed. Methods: Five patients with ragweed-allergic asthma underwent bronchoscopy and segmental bronchial challenge with either normal saline or short ragweed extract in two segments of one lung. In a third segment of the opposite lung, 12 successive BALs ...
Invasive pulmonary aspergillosis (IPA) remains a major cause for morbidity and mortality in patients (pts) with hematologic malignancies. As culture-based methods only yield results in a minority of patients, using non-culture-based methods for detection of aspergillosis in clinical specimens becomes increasingly important. Analyzing bronchoalveolar lavage (BAL) samples with polymerase chain reaction (PCR) is promising, however, the influence of current antifungal drugs on the performance of this diagnostic tool remains controversial.. The aim of the trial is to elucidate on the performance of BAL PCR under antifungal treatment.. Patients with high risk of invasive aspergillosis and lung infiltrates are sampled via BAL, the sample is analyzed for fungal DNA by Apsergillus specific PCR. Clinical data including treatment data is assessed and evaluated. ...

Myeloid dendritic cells (DCs) are increased in the airway wall of patients with chronic obstructive pulmonary disease (COPD), and postulated to play a crucial role in COPD. However, DC phenotypes in COPD are poorly understood. Function-associated surface molecules on bronchoalveolar lavage fluid (BALF) DCs were analyzed using flow cytometry in current smokers with COPD, in former smokers with COPD and in never-smoking controls. Myeloid DCs of current smokers with COPD displayed a significantly increased expression of receptors for antigen recognition such as BDCA-1 or Langerin, as compared with never-smoking controls. In contrast, former smokers with COPD displayed a significantly decreased expression of these receptors, as compared with never-smoking controls. A significantly reduced expression of the maturation marker CD83 on myeloid DCs was found in current smokers with COPD, but not in former smokers with COPD. The chemokine receptor CCR5 on myeloid DCs, which is also important for the uptake and
Background. In acute respiratory distress syndrome or pneumonia, a procoagulant shift is observed in bronchoalveolar lavage fluid (BALF). The effect of a primarily extrapulmonary infection on coagulation and fibrinolysis in the pulmonary compartment is unclear. Methods. In 35 patients, 87 bronchoalveolar lavages were performed on the day of operation for secondary peritonitis (day 0) and on days 2 and 3 after surgery. Two noninfectious control groups were included: subjects undergoing bronchoalveolar lavage after elective surgery (n = 8) and those undergoing long-term mechanical ventilation (n = 10). Results. In BALF from patients with peritonitis, a tissue factor (TF)/factor VIIaâ€mediated activation of coagulation was shown (high levels of thrombin-antithrombin complexes). Levels of fibrinolysis activators decreased rapidly after day 0, whereas levels of inhibitors increased. The net effect was reduced fibrinolysis (plasminogen activator activity). The sequential comparison of plasma ...
BackgroundPneumonia carries significant morbidity and mortality in leukemic and bone marrow transplant patient. The development of pulmonary infiltrates in the setting of such immunocompromise raises concern for both infectious and non-infectious etiologies, some of which are potentially treatabl. Performing bronchoscopy provides several different options for sampling the lower respiratory tract. Among these, bronchoalveolar lavage (BAL) is especially effective at collecting samples from the alveoli and has been shown to be associated with less risk than transbonchial biops. We sought to examine the effect of antimicrobial treatment on BAL results in a large study population of leukemic and bone marrow transplant patients.Subjects and MethodsThis retrospective chart review was performed at a single academic cancer center. A power analysis was performed to determine the appropriate sample size. The patients were selected from those who had undergone an inpatient bronchoscopy in reverse chronological
We report the case of a 55-year-old woman, former smoker since September 2012 (18 pack-years), with a history of allergic rhinoconjunctivitis and bronchial asthma. No infiltrates were observed in a chest X-ray performed in 2012. Skin prick tests showed sensitization to cat dander and grass and olive pollen.. She was admitted in 2014 for an acute episode of dyspnea, breath sounds, and non-productive cough without fever. Chest X-ray revealed an alveolointersticial pattern predominantly in the lung bases. Chest computed tomography showed bilateral patchy ground glass infiltrates. Bronchoscopy was performed with transbronchial biopsy and bronchoalveolar lavage: neutrophils: 11%; eosinophils: 85.9%; lymphocytes: 0.6%. Biopsy showed a histological pattern of pulmonary eosinophilia suggestive of chronic eosinophilic pneumonia (CEP), with a focal pattern typical of organizing pneumonia. Lung function tests highlighted a restrictive pattern with carbon monoxide diffusion changes: FVC 1830 - 59%; FEV1 ...

Table II shows differential count for the three patients. There is increased neutrophil count after CPB with predominance of macrophages in both samples.. DISCUSSION. Inflammation may be understood as a protective response against the consequences of tissue aggression, organ dysfunction and cell necrosis 10, being a systemic process present even in the absence of systemic inflammatory response syndrome (SIRS) 11. However, if SIRS evolves to organ dysfunction, the inflammatory response may be noxious 10 with pulmonary function changes, renal failure, multiorgan failure syndrome (MOFS) and shock 11.. Postoperative pulmonary dysfunction is frequent and contributes to morbidity, mortality and hospitalization-related costs 12. The understanding of postoperative pulmonary dysfunction pathophysiology is critical for postoperative clinical pulmonary complication evaluation and the definition of therapeutic regimens.. Postoperative pulmonary dysfunction pathogenesis is associated to changes in gas ...
Case Report Our case is a 4 month old, Sudanese boy, residing in Qatar, who presented to our hospital with fever for two weeks. He remained febrile in the hospital for two weeks, despite receiving Intravenous antibiotics for presumed partially treated meningitis. He also received IVIG for the suspicion of atypical Kawasaki. Computerised tomography of the head and abdomen and bone marrow studies were also inconclusive. The mother subsequently revealed that a previous child had died during infancy with prolonged fever and no specific diagnosis. This alerted the treating physicians to the possibility of immunodeficiency. Our patient had received BCG vaccine at birth without any complications, and three gastric aspirate samples were negative for tuberculosis. A broncho-alveolar lavage was performed, despite the absence of any respiratory symptoms, to exclude any unusual organisms causing prolonged fever. The broncho-alveolar lavage revealed mycobacterium tuberculosis which was resistant to Isoniazid ...

AU - Clayton, Marcia E.. AU - Gossman, Gail L.. AU - Kendall, Todd J.. AU - Rennard, Stephen I.. PY - 1987/9. Y1 - 1987/9. N2 - Several proteins have been described that can modulate the activity of the complement component C5a, a potent chemoattractant for neutrophils. One of these inhibitors has been termed chemotactic factor inactivator (CFI). We hypothesized that CFI was antigenically present in normal human serum and that antigenic levels would correlate with the ability of serum to inhibit C5a. To test this hypothesis, CFI was purified from normal human serum, antibodies to CFI were developed in rabbits, and these reagents were used to develop an enzyme-linked immunoadsorbent assay to measure CFI. Sera from 32 normal volunteers were assayed for CFI and found to contain 77 ± 29 μg/ml (range 17 to 137 μg/ml). ...

BioAssay record AID 423142 submitted by ChEMBL: Effect on pulmonary inflammation in BALB/c mouse lung assessed as change in peribronchiolar inflammation after 5 days by histopathological analysis.
COPD is an inflammatory disease of the airways characterised by increased levels of proinflammatory markers in lung tissue, and associated bronchial alveolar lavage (BAL) fluid and sputum. Increased sputum neutrophil levels have been correlated with disease progression and established as a primary biomarker of disease activity. Other biomarkers identified in sputum, such as CXCL8 (IL-8), club cell secretory protein (CC-16) and others, have been associated with disease activity, and in some studies correlate with disease progression.18 ,19. Previous studies have shown that both neutrophil and macrophage cell populations are increased in sputum and BAL samples taken from patients with COPD compared with those from disease-free patients,20 and that this increase is correlated with disease severity.21 ,22 Macrophages, in particular alveolar macrophages, are the most abundant type of immune cell found in the small airways, and they seem to accumulate in areas of tissue damage in the lungs.23 ,24 This ...

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. Forty-six BAL specimens were obtained from lung transplant recipients and divided into two aliquots: whole BAL and acellular BAL, the latter processed with a low-speed, short-duration centrifugation step. Both aliquots were analyzed via bacterial 16S rRNA gene pyrosequencing. The BAL specimens represented a wide spectrum of lung health, ranging from healthy and asymptomatic to acutely infected. Bacterial signal was detected in 52% of acellular BAL aliquots, fewer than were detected in whole BAL (96%, p ≤ 0.0001). Detection of bacteria in acellular BAL was associated with indices of acute infection [BAL neutrophilia, high total

TY - JOUR. T1 - Cytotoxic drug-induced lung injury. AU - Snyder, Linda S.. AU - Hertz, Marshall I.. PY - 1988/9/1. Y1 - 1988/9/1. N2 - Cytotoxic drug-induced pulmonary disease is a major cause of morbidity and mortality in immunocompromised patients. It is estimated that 20% of all patients receiving cytotoxic drugs will develop a symptomatic pulmonary reaction. Therefore, the possibility of a toxic drug reaction must be considered in all patients developing pulmonary disease during or following treatment with these agents. Clinical manifestations of lung toxicity are nonspecific and parallel the signs and symptoms of diffuse lung infection and malignant disease in the chest. For this reason, the diagnosis of cytotoxic drug-induced lung damage is one of exclusion of the various opportunistic infections that afflict this patient population. This typically requires careful microbiologic studies of bronchoalveolar lavage (BAL) samples and lung tissue. The diagnosis of cytotoxic drug-induced lung ...
An alteration in the balance between a T-helper type 2 cell (Th2) response and a Th1 response may predispose to the development of bronchial asthma. Interleukin-18 (IL-18) has an ability to promote both Th1 and Th2 responses, depending on the surrounding cytokine environment. Reactive oxygen species (ROS) play a crucial role in the pathogenesis of airway inflammation and hyperresponsiveness. Recent studies have demonstrated that antioxidants are able to reduce airway inflammation and hyperreactivity in animal models of asthma. In this study, we used a C57BL/6 mouse model of allergic asthma to examine the effects of antioxidants on the regulation of IL-18 expression. Our present study with ovalbumin-induced murine model of asthma revealed that ROS production in cells from bronchoalveolar lavage fluids was increased and that administration of l-2-oxothiazolidine-4-carboxylic acid or α-lipoic acid reduced the increased levels of ROS, the increased expression of IL-18 protein and mRNA, airway ...

Cytokines produced by activated TH2-type CD4+ T cells in the airway may contribute to late asthmatic responses by mechanisms that include eosinophil accumulation.
This is because co-receptor CD4 amplifies the signal produced for the T-cell receptor by recruiting lymphocyte protein kinase Lck, which consequently triggers a cascade of gatherings leading to T-cell activation. Curiously, DHLA didnt downregulate CD4 from the surface area of human peripheral blood mononuclear cells [a hundred forty five]. Instead or Along with CD4 downregulation, the immunomodulatory Houses of LA may perhaps include the upregulation of cAMP in T-cells and organic killer cells [146]. Mobile migration and neovascularization were being also inhibited by LA (86 μg/day in consuming h2o) in c57/black mice injected with Kaposis sarcoma inside of a matrigel sponge, in addition to in nude mice injected with KS cells [147]. In the mouse product of bronchial asthma, dietary LA considerably attenuated airway hyper-responsiveness, reduced the eosinophil depend among the bronchoalveolar lavage cells, and considerably improved pathologic lesion scores with the lungs [148]. LA inhibits ...
Results C57 mice demonstrated a higher total bronchoalveolar lavage (BAL) and BAL lymphocyte count at 3 and 7 days after intraperitoneal infection compared with BALB mice. There were no differences in BAL cytokine production; however, we were able to demonstrate differences in CMV DNA load in the lungs of BALB mice compared with that of C57 mice. In addition, there appeared to be increased whole-lung production of the TH2 cytokine IL-10 in the BALB mice versus the C57 mice. ...

In our sample, male patients without a visible cause prevailed, as found in other studies (6). In respect to age, 68.2% were up to 3 years old, compatible with the period in which children are more susceptible to respiratory infections. Furthermore, infants and young children are more likely to develop chronic respiratory problems after infections because of the physiological characteristics of their airways (1). More than two thirds of the cases were of asthma and neuropathy since these diseases are usually associated to a more affected respiratory tract than that of the general population (1,2). In our study only one patient had oxygen desaturation this complication (4.5%), in a similar frequency reported in the literature (6-10 ...

The CD3(+)CD161(+) T cell subpopulation resides in the liver, intestine and skin, but it has the capacity for tissue migration; however, the presence of resident CD3(+)CD161(+) T cells in th …
Adults with CF given a bronchoscopy and bronchoalveolar lavage (BAL) as alternative to a sputum sample had no serious side effects in study.
This study examines the influence of Bu-Zhong-Yi-Qi-Tang (Hochuekkito; TJ-41) on the inflammatory response in alveolar macrophage in hyperglycemic mice. BALB/c mice (males, six to eight weeks old) were divided into three groups: A, B, and C. From the outset, group A and B were fed an ordinary diet, whereas TJ-41 was given to group C. After the initiation of these diets, intraperitoneal injection of streptozotocin (STZ), 250mg/g in mice of groups B and C. Four weeks after the start of these diets, blood-glucose levels were measured, and bronchoalveolar lavage (BAL) was performed. Alveolar macrophages were sampled, and those demonstrating blood-glucose levels of more than 200 mg/dL were selected for use. Toll-like receptor (TLR) ligands (TLR2: peptidoglycan [PGN], TLR4: LPS, TLR5: flagellin [FLG]) were employed to stimulate pulmonary-alveolar macrophages, and ELISA was used to measure TNF-a production. TLR expression on pulmonary-alveoli surface was evaluated on the basis of the emergence of each ...

HIA has previously discussed the coding of bronchoscopy with bronchoalveolar lavage (BAL). The coding of procedures performed via bronchoscopy has become complicated in ICD-10-PCS. The coder must now think about the objective of the procedure to assign the correct root operation, the correct body part being addressed, and the correct approach and whether or not the intent of any removal of tissue or fluid was diagnostic..
