| Induced sputum is a useful technique for assessing airway inflammation, but its role in the diagnosis of lung disease in immunosuppressed patients needs further investigation. This study compared the use of induced sputum and BAL in the diagnosis of pneumocystosis, in HIV patients. From January 1, 2001, to December 30, 2002, HIV-positive patients older than 14 were evaluated at a hospital in Florianópolis, Santa Catarina, Brazil. Patients with respiratory symptoms for seven days or longer, with a normal or abnormal chest X-ray, and those without respiratory symptoms but with an abnormal chest X-ray, were included in the study. All patients were submitted to clinical, radiological and laboratory evaluation, after which induced sputum and bronchoscopy with... |

| BACKGROUND: Bacterial pneumonias have been overcoming pneumocytosis in frequency. Controversy still remains about how to manage immunocompromised patients and those with lung diseases. Sputum analysis is a noninvasive and simple method, and when interpreted according to specific criteria it may help with diagnosis. We conducted a study to evaluate sensitivity, specificity, positive and negative predicted values, and the accuracy of induced sputum (IS) for bacterial community-acquired pneumonia diagnosis in HIV-positive patients. MATERIAL AND METHODS: This cross sectional study evaluated a diagnostic procedure in a reference hospital for HIV patients in Florianópolis, SC, Brazil. From January 1, 2001 to September 30, 2002, 547 HIV-positive patients were... |

| This study was performed to assess the efficiency of polymerase chain reaction (PCR) directly from sputum for the diagnosis of pulmonary tuberculosis by comparison between HIV-positive and HIV-negative individuals. Sputum samples were collected from hospitalized patients admitted with a clinical diagnosis of pulmonary tuberculosis, and subjected to smear microscopy, culture on LJ medium and detection of M. tuberculosis by PCR. Sensitivity, specificity, and predictive values (positive and negative) were calculated using smear and/or culture at day 42 as the gold standard, by comparing the yield in HIV-positive and HIV-negative individuals. Regardless of serostatus, the technique's yield had 62% sensitivity, 70% specificity, 79% positive predictive value,... |
