Tuberculosis incidence and risk factors among patients living with HIV/AIDS in public health service institutions in Brasilia, Federal District

In order to estimate the incidence of and risk factors for developing tuberculosis, the clinical charts of a retrospective cohort of 281 HIV-positive adults, who were notified to the AIDS Program of the Health Department of Brasilia in 1998, were reviewed in 2003. All the patients were treatment-naive regarding antiretroviral therapy at the time of inclusion in the cohort. Twenty-nine patients were identified as having tuberculosis at the start of the study. Thirteen incident tuberculosis cases were identified during the 60 months of follow-up, with an incidence density rate of 1.24/100 person-years. Tuberculosis incidence was highest among patients with baseline CD4+ T-lymphocyte counts < or = 200 cells/microl who were not using antiretroviral therapy (incidence = 5.47; 95% CI = 2.73 to 10.94). Multivariate analysis showed that baseline CD4+ T-lymphocyte counts < or = 200 cells/microl (adjusted hazard ratio [AHR] = 5.09; 95% CI = 1.27 to 20.37; p = 0.02) and non-use of antiretroviral therapy (AHR = 12.17; 95% CI = 2.6 to 56.90; p = 0.001) were independently associated with increased risk of tuberculosis.

Trajetória da política de atenção básica à saúde no Distrito Federal, Brasil (1960 a 2007): análise a partir do marco teórico do neo-institucionalismo histórico

This article analyzes the history of primary health care policy in the Federal District, Brazil, based on the theoretical framework of historical neo-institutionalism, identifying the predominant configurations and trends in the various administrations of the State Health Secretariat (SES-DF) from 1960 to 2007. The study indicates that the characteristics of the Federal Districts health policy are dependent on the history of the original health system plans for setting priorities and goals, as well as for the health systems implementation. This influence, in addition to the centralization of decision-making processes and limited political participation, can contribute to making primary care ancillary to hospital care, thus jeopardizing its potential to produce change in the health care model.

Added Value of QuantiFERON TB-Gold in-Tube for Detecting Latent Tuberculosis Infection among Persons Living with HIV/AIDS

Objective. To evaluate the added value of QuantiFERON TB-Gold in-Tube (QTF-GIT) over the tuberculin skin testing (TST) for detecting latent tuberculosis (TB) infection (LTBI) among patients with AIDS in a city with a low TB incidence rate (11.1/100,000 inhabitants) and universal BCG coverage. Methods. Three hundred consecutive patients with AIDS in eight outpatient sexually transmitted disease public clinics in Brasilia were submitted to QFT-IT and TST between May 2011 and March 2013. A positive result of either test was considered to be LTBI. Results. Median CD4-cell count was 477.5 cells/mm3; 295 (98.3%) were using antiretroviral therapy. Eighteen patients (6%, 95% CI: 3.6%–9.3%) had LTBI, of whom 4 (1.3%, 95% CI: 0.04%–2.63%) had only a positive TST, 8 (2.7%, 95% CI: 0.8%–4.5%) had only a QFT-GIT positive test, and 6 (2%, 95% CI: 0.4%–3.6%) had positive results for both tests. This represents an 81.8% relative increase in LTBI detection when QFT-GIT is added to TST. The concordance between both tests was 96% (k = 0.48). Conclusions. The QFT-GIT alone was more effective to detect LTBI than TST alone and had an 81% added value as an add-on sequential test in this population with mild immunosuppression. The cost-effectiveness of these strategies remains to be evaluated.

O percentual de casos de hanseniase entre os contatos intradomiciliares foi de 46,4%, sendo que 44,9% deles com resultado do teste do ML Flow positivo. O estudo sugere incorporar o teste ML Flow nos servicos de saude, uma vez que o mesmo auxilia na classificacao operacional da doenca, controle de contatos intradomiciliares com resultado do teste positivo, visando a deteccao precoce dos casos suspeitos de hanseniase.

Syndromic surveillance: etiologic study of acute febrile illness in dengue suspicious cases with negative serology. Brazil, Federal District, 2008

With the aim of identifying the etiology of acute febrile illness in patients suspected of having dengue, yet with non reagent serum, a descriptive study was conducted with 144 people using secondary serum samples collected during convalescence. The study was conducted between January and May of 2008. All the exams were re-tested for dengue, which was confirmed in 11.8% (n = 17); the samples that remained negative for dengue (n = 127) were tested for rubella, with 3.9% (n = 5) positive results. Among those non reactive for rubella (n = 122), tests were made for leptospirosis and hantavirus. Positive tests for leptospirosis were 13.9% (n = 17) and none for hantavirus. Non reactive results (70.8%) were considered as Indefinite Febrile Illness (IFI). Low schooling was statistically associated with dengue, rubella and leptospirosis (p = 0.009), dyspnea was statistically associated with dengue and leptospirosis (p = 0.012), and exanthem/petechia with dengue and rubella (p = 0.001). Among those with leptospirosis, activities in empty or vacant lots showed statistical association with the disease (p = 0.013). Syndromic surveillance was shown to be an important tool in the etiologic identification of IFI in the Federal District of Brazil.

Distribuição espacial da hanseníase na população escolar em Paracatu - Minas Gerais, realizada por meio da busca ativa (2004 a 2006)

The detection rate of leprosy in the district of Paracatu is high in people younger than fifteen years of age, with about 6.8/10,000 inhabitants in 2003, therefore classified as hyperendemic. The study aims at territorially distributing the cases of leprosy in teenagers and children still in school, using the case finding strategy. A prospective cohort and ecologic study was used with 16,623 students between January 2004 and June 2006. An Excel spreadsheet was built for the database and the statistical analysis included c2, Confidence Interval - (IC) of 95% and Relative Risk (RR). The Auto-CAD release 2000 was used for geoprocessing information. 68 cases of the disease were diagnosed (25.1%, multibacilar forms). About 85.2% lived in the urban area, 55.8% were women, and the 10 to 14 year-old age group prevailed (61.7%; 95%IC: 0.49-0.89%). There was an increase of 38.2% in the case detection rate, giving visibility to the unknown prevalence. Considering case finding in 2004, the microregions of Alto do Acude and Vista Alegre presented a higher case detection with 41.5/10,000 inhabitants; and RR=10.9 higher than the center of Paracatu, with the detection of 3.8/10,000 inhabitants. In 2005, the microregions of Paracatuzinho, Chapadinha, Sao Joao Evangelista I and II, Bandeirantes, Aeroporto and Bom Pastor stand out, with the detection of 21.8/10,000 inhabitants, and Relative Risk=8.7 times higher than Nossa Senhora de Fatima and J.K with the detection of 2.5/10,000 inhabitants. Geoprocessing of the information, through case finding among students, allowed visibility of the high detection rate of leprosy by region, allowing improvement in the surveillance of the disease in Paracatu.

Relationship between climatic factors and air quality with tuberculosis in the Federal District, Brazil, 2003–2012

INTRODUCTION Despite the high rate of tuberculosis indicators in Brazil, the Federal District shows a low prevalence of the disease. OBJECTIVE To analyze the relationship between climatic factors and air quality with tuberculosis in the Brazilian Federal District. METHODOLOGY This was an ecological and descriptive study comparing 3927 new cases of Tuberculosis registered at the Federal District Tuberculosis Control Program with data from the National Institute of Meteorology, Brazilian Institute of Geography and Statistics, Brazilian Agricultural Research Institute, Brasilia Environmental Institute, and the Federal District Planning Company. RESULTS From 2003 to 2012, there has been a higher incidence of Tuberculosis (27.0%) in male patients in the winter (27.2%). Patients under 15 years of age (28.6%) and older than 64 years (27.1%) were more affected in the fall. For youth and adults (15-64 years), the highest number of cases was reported during winter (44.3%). The disease was prevalent with ultraviolet radiation over 17MJ/m2 (67.8%; p=<0.001); relative humidity between 31.0% and 69.0% (95.8% of cases; p=<0.00); 12h of daily sunlight or more (40.6%; p=0.001); and temperatures between 20°C and 23°C (72.4%; p=<0.001). In the city of Taguatinga and surrounding area, pollution levels dropped to 15.2% between 2003 and 2012. Smoke levels decreased to 31.9%. In the Sobradinho region, particulate matter dropped to 13.1% and smoke to 19.3%, coinciding with the reduction of Tuberculosis incidence rates during the same period. CONCLUSION The results should guide surveillance actions for Tuberculosis control and elimination and indicate the need to expand observation time to new climate indicators and air quality.

A diagnosis of pulmonary tuberculosis and drug resistance among inmates in Mato Grosso do Sul, Brazil

INTRODUCTION High endemic levels of pulmonary tuberculosis in prisons result from overcrowding, limited access to healthcare, delayed diagnosis, sustained transmission owing to poor control measures, and multidrug resistance. This study evaluated locally implemented measures for early pulmonary tuberculosis diagnosis and evaluated resistance to anti-tuberculosis drugs. METHODS This transversal study employed data from the Mato Grosso do Sul State Tuberculosis Control Program obtained from 35 correctional facilities in 16 counties for 2 periods (2007-2010 and 2011-2014). RESULTS Statewide prevalence (per 100,000) was 480.0 in 2007 and 972.9 in 2014. The following indicators showed improvement: alcohol-acid-fast bacillus testing (from 82.7% to 92.9%); cultures performed (55.0% to 81.8%); drug susceptibility testing of positive cultures (71.6% to 62.4%); and overall drug susceptibility testing coverage (36.6% to 47.4%). Primary and acquired resistance rates for 2007-2014 were 21.1% and 30.0%, respectively. Primary and acquired multidrug resistance rates were 0.3% and 1.3%, respectively. CONCLUSIONS Prevalence rates increased, and laboratory indicators improved as a result of capacity building and coordination of technical teams and other individuals providing healthcare to inmates. Resistance rates were high, thereby negatively affecting disease control.
