Background: Tuberculosis become important challenge to health care settings. Brazil has high prevalence of the disease and Rio de Janeiro has high incidence rates with 30% of cases notified at hospitals.Objective: To evaluate prevalence of initial and acquired drug resistance at a general hospital, reference for aids treatment in Rio de Janeiro and to identify associated factors.Methods: Mycobacterium tuberculosis strains from 165 patients were analyzed, between August 1996 and February 1998.Results: Twenty per cent (33/165) were resistant to at least one drug; 13% (12/165) to isoniazid; 3.64% (6/165) to rifampin and 3.64% (6/165) to both. Among HIV seropositive subjects (52/165); 28.85% (15/52) were resistant to at least one drug. Acquired resistance occurred in 15.79% of 19 patients that mentioned previous antiTB treatment. Association statistically significant was found with non cavitation on X-ray in bivariate analyses (P=0.05). Eighty four patients refereed no previous treatment (NPT). Resistance to 1 or more drugs was found in 28.57% (24/84) of NPT patients. Association statistically significant with initial resistance was found with health care workers (P=0.004), unemployment (P=0.03), and diarrhea (P=0.01) in bivariate analyses. On multivariate analyses, health care workers (P=0.002) remained significantly associated with initial resistance.Conclusions: High resistance rates was found. It corroborates that hospitals needs attention for TB control especially which concerns to health care works infection.

SETTING: Rio de Janeiro, RJ, Brazil, a high tuberculosis (TB) burden city.OBJECTIVE: To compare the sociodemographics, clinical characteristics, care process indicators (CPIs) and treatment outcomes among adolescents with pulmonary TB (PTB) and those with PTB + extrapulmonary TB (EPTB), who underwent testing with Xpert® and sputum culture.DESIGN: This was a retrospective study of data from three national databases from 2014 to 2016 of adolescents (aged 10–18 years) residing and notified in Rio de Janeiro City. Three groups were identified according to their Xpert and culture results: Group 1, Xpert- and culture-positive; Group 2, Xpert-positive and culture-negative; and Group 3, Xpert- and culture-negative. Study CPIs were as follows: the time between ‘sample collection and Xpert result release', ‘sample collection and treatment initiation' and ‘notification and treatment outcome'.RESULTS: Of 258 adolescents included in the study, 223 (86.4%) were in Group 1, 20 (7.8%) in Group 2 and 15 (5.8%) in Group 3. Groups 1 and 2 had a similar profile. Compared to Group 1, Group 3 had a higher proportion of HIV-positive cases (21.4% vs. 3.0%, P = 0.016), adolescents with a hospital diagnosis (53.3% vs. 7.6%, P < 0.001), and PTB + EPTB cases (20% vs. 0.4%; P < 0.001). There were no statistically significant differences in CPIs or treatment outcomes.CONCLUSION: The clinical diagnosis was decisive in more critical or complex patients, despite Xpert-negative results.
