13. Bronchial hyperresponsiveness and analysis of induced sputum cells in Crohn's disease
With the aim of investigating the presence of latent inflammatory process in the lungs of patients with Crohn's disease, 15 patients with Crohn's disease were evaluated by spirometry, the methacholine challenge test, induced sputum, and skin tests for inhaled antigens. Serum IgE, erythrocyte sedimentation rate and hematocrit were also determined. The patient

14. Microbiology profile and severity markers in CF patients / Perfil microbiologico e indicadores de gravidade em pacientes com fibrose cistica
Objective: To identify the prevalence of organisms in sputum from patients with CF and determine the correlations among the severity markers of disease: Schwachman score, Bhalla score, nutritional status and lung function. Methods: Prospective study (2001-04) performed at the State University of Campinas Medical School.Unicamp. The secretions were obtained f

15. Airway inflammation in steroid-naïve asthmatics: characteristics of induced sputum
BACKGROUND: Airway inflammation, acknowledged as an important feature of asthma, can be assessed by the examination of induced sputum. OBJECTIVE: To determine the pattern of inflammatory cells in induced sputum from stable steroid-naïve asthmatics, in Florianópolis, Santa Catarina. METHOD: The induced sputum from 34 asthmatics using exclusively inhaled bro

16. Admission for tuberculosis to a university hospital
Patients with active tuberculosis (Tb) may be admitted to a hospital for different conditions, and not have Tb as their main diagnosis. In this study, 141 inpatient Tb cases are analyzed, which were notified to the São Paulo Hospital Central Control of Infectious Diseases from August, 1999, through April, 2001, with identification of causes, risk factors, a

17. Use of induced sputum specimens for microbiologic diagnosis of infections due to organisms other than Pneumocystis carinii.
The optimal diagnostic approach to pneumonia provides a rapid microbiologic identification of pulmonary pathogens by the least invasive means. The technique of sputum induction has been useful in the evaluation of patients with Pneumocystis carinii or mycobacterial pneumonia. It is not known whether induced sputum samples are preferable for the detection of

18. Comparative recovery of cytomegalovirus from saliva, mucolysed induced sputum, and bronchoalveolar lavage fluid from patients at risk for or with acquired immunodeficiency syndrome.
The recovery rates of cytomegalovirus from mucolysed induced sputum samples and bronchoalveolar lavage fluid obtained from individuals at risk for or with acquired immunodeficiency syndrome were compared. It was demonstrated that cytomegalovirus could be reliably recovered from mucolysed induced sputum, and such recovery was highly predictive of recovery fro

19. Inhibition of Isoniazid-Induced Expression of Mycobacterium tuberculosis Antigen 85 in Sputum: Potential Surrogate Marker in Tuberculosis Chemotherapy Trials
Mycobacterium tuberculosis antigen 85 is induced in vitro by isoniazid (INH); its sustained induction in sputum during tuberculosis (TB) therapy predicts relapse. In this trial, rifampin or rifalazil inhibited the induction of sputum antigen 85 by INH in a dose-dependent fashion. This approach may facilitate the evaluation of new TB drugs.

20. Comparison of monoclonal antibody and calcofluor white stains for the detection of Pneumocystis carinii from respiratory specimens.
Three monoclonal antibody staining kits, from Genetic Systems, Disease Detection International, and Meridian Diagnostics, were compared with calcofluor white for the direct detection of Pneumocystis carinii in respiratory specimens. Of the 150 specimens tested, 23 were found positive for P. carinii by any of the four stains; 13 were bronchoalveolar lavage, 7

21. Angiotensin converting enzyme (ACE) inhibitor-induced cough and substance P.
BACKGROUND: Angiotensin converting enzyme (ACE) inhibitors cause coughing in 5-10% of patients, but the exact mechanisms of this effect are still unclear. In the airways ACE degrades substance P so the cough mechanism may be related to this peptide. METHODS: Nine patients who developed a cough and five patients who did not develop a cough when taking the ACE

22. Use of induced sputum cell counts to investigate airway inflammation in asthma.
BACKGROUND: Airway inflammation is considered to be important in asthma but is relatively inaccessible to study. Less invasive methods of obtaining sputum from patients unable to produce it spontaneously should provide a useful investigational tool in asthma. METHODS: A method to induce sputum with inhaled hypertonic saline was modified for use in 17 asthmat

23. Cytokine expression in normal, atopic, and asthmatic subjects using the combination of sputum induction and the polymerase chain reaction.
BACKGROUND--The importance of cytokines in the asthmatic inflammatory response is becoming apparent. The aim of this study was to determine whether the non-invasive method of induced sputum combined with the polymerase chain reaction would allow the detection of messenger RNA (mRNA) encoding a range of cytokines on a qualitative basis. METHODS--Four groups w

24. Sputum and ciliary inhibition in asthma.
Twenty-eight sputum samples collected from 20 patients with chronic bronchial asthma of atopic and intrinsic clinical types were incubated with human bronchial explants to study their influence on ciliary motility. Of these, 19 (68%) of the sputa exerted a ciliary inhibitory effect of varying degree in a two-hour period. Analysis of the data indicates that (
