Inequalities in HAART uptake and differential survival according to exposure category in Rio de Janeiro, Brazil / Desigualdades no acesso à HAART e diferenças de sobrevida de acordo com a categoria de exposição ao HIV no Rio de Janeiro, Brasil / Desigualdades en el consumo de la TARGA y supervivencia diferencial según la categoría de exposición en Río de Janeiro, Brasil

Abstract: Despite substantial improvement in prognosis and quality of life among people living with HIV/AIDS (PLWHA) in Brazil, inequalities in access to treatment remain. We assessed the impact of these inequalities on survival in Rio de Janeiro over a 12-year period (2000/11). Data were merged from four databases that comprise the national AIDS monitoring system: SINAN-AIDS (Brazilian Information System for Notificable Diseases; AIDS cases), SISCEL (laboratory tests), SICLOM (electronic dispensing system), and SIM (Brazilian Mortality Information System), using probabilistic linkage. Cox regressions were fitted to assess the impact of HAART (highly active antiretroviral therapy) on AIDS-related mortality among men who have sex with men (MSM), people who inject drugs (PWID), and heterosexuals diagnosed with AIDS, between 2000 and 2011, in the city of Rio de Janeiro, RJ, Brazil. Among 15,420 cases, 60.7% were heterosexuals, 36.1% MSM and 3.2% PWID. There were 2,807 (18.2%) deaths and the median survival time was 6.29. HAART and CD4+ > 200 at baseline were associated with important protective effects. Non-whites had a 33% higher risk of dying in consequence of AIDS than whites. PWID had a 56% higher risk and MSM a 11% lower risk of dying of AIDS than heterosexuals. Non-white individuals, those with less than eight years of formal education, and PWID, were more likely to die of AIDS and less likely to receive HAART. Important inequalities persist in access to treatment, resulting in disparate impacts on mortality among exposure categories. Despite these persistent disparities, mortality decreased significantly during the period for all categories under analysis, and the overall positive impact of HAART on survival has been dramatic.

Resumo: Apesar de uma melhora substancial no prognóstico e na qualidade de vida de pessoas vivendo com HIV/aids (PVHA) no Brasil, permanecem desigualdades no acesso ao tratamento. Avaliamos o impacto dessas desigualdades na sobrevida na cidade do Rio de Janeiro ao longo de 12 anos (2000/11). Os dados foram consolidados a partir de quatro bases que constituem o sistema nacional de monitoramento da aids: SINAN-aids (Sistema de Informação de Agravos de Notificação; casos de aids), SISCEL (exames laboratoriais), SICLOM (controle logístico de medicamentos) e SIM (Sistema de Informações sobre Mortalidade), usando relacionamento probabilístico. As regressões de Cox foram ajustadas para avaliar o impacto da HAART (terapia antirretroviral altivamente ativa) na mortalidade relacionada à aids entre homens que fazem sexo com homens (HSH), usuários de drogas injetáveis (UDI) e heterossexuais diagnosticados com aids entre 2000 e 2011 na cidade do Rio de Janeiro. Dos 15.420 casos, 60,7% eram heterossexuais, 36,1% HSH e 3,2% UDI. Houve 2.807 óbitos (18,2%) e a sobrevida mediana foi 6,29 anos. Houve associação significativa entre HAART e contagem de CD4+ > 200 na linha de base e importantes efeitos protetores. Comparados aos brancos, os não-brancos tiveram um risco 33% maior de morrer de aids. Os UDI tiveram um risco 56% maior, enquanto HSH tiveram um risco 11% menor de morrer de aids, comparados aos heterossexuais. Os indivíduos não-brancos, aqueles com menos de oito anos de escolaridade e UDI mostraram probabilidade mais alta de não receber HAART e de morrer de aids. No Rio de Janeiro, persistem desigualdades importantes no acesso ao tratamento, que resultam em impactos diferenciados na mortalidade de acordo com as categorias de exposição. Apesar da persistência dessas disparidades, a mortalidade diminuiu significativamente ao longo do período em todas as categorias analisadas, e o acesso à HAART teve impacto dramático no tempo de sobrevida.

Resumen: Pese a la mejora sustancial en el pronóstico y calidad de vida entre las personas que viven con VIH/SIDA (PLWHA) en Brasil, persisten las desigualdades en el acceso al tratamiento. Evaluamos el impacto de estas desigualdades en la supervivencia en Río de Janeiro, durante un período de 12 años (2000/11). Los datos fueron recabados de cuatros bases de datos que comprenden el sistema nacional de monitoreo del SIDA: SINAN-SIDA (Sistema de Información de Agravios de Notificación; casos de SIDA), SISCEL (pruebas de laboratorio), SICLOM (sistema dispensador electrónico), y SIM (Sistema de Información sobre la Mortalidad), usando una vinculación probabilística. Las regresiones de Cox fueron usadas para evaluar el impacto de la TARGA (terapia antirretroviral de gran actividad) en la mortalidad relacionada con el SIDA, entre hombres que tienen sexo con hombres (HSH), individuos que se inyectan drogas por vía intravenosa (PWID por sus siglas en inglés), y heterosexuales diagnosticados con SIDA, entre 2000 y 2011, en la ciudad de Río de Janeiro, RJ, Brasil. Entre 15.420 casos, un 60,7% eran heterosexuales, un 36,1% HSH y un 3,2% PWID. Hubo 2.807 (18.2%) muertes y el tiempo medio de supervivencia fue 6,29. TARGA y CD4+ > 200 en la base de referencia estuvieron asociados con efectos importantes de protección. Los no-blancos tuvieron un riesgo un 33% mayor de morir a consecuencia de SIDA que los blancos. Los PWID tuvieron un riesgo un 56% mayor, y los HSH un riesgo un 11% menor, de morir de SIDA que los heterosexuales. Los no-blancos, con menos de ocho años de educación formal, y los PWID, eran más propensos a morir de SIDA y menos a recibir TARGA. Existen importantes inequidades en el acceso al tratamiento, resultando en efectos dispares en la mortalidad entre las diferentes categorías exposición. A pesar de estas persistentes disparidades, la mortalidad decreció significativamente durante el periodo para todas las categorías bajo análisis, y el impacto general positivo del TARGA en la supervivencia había sido importantísimo.

Prevalência de sarcoma de Kaposi em pacientes com aids e fatores associados, São Paulo-SP, 2003-2010 / Prevalencia de sarcoma de Kaposi en pacientes con SIDA y factores asociados, São Paulo-SP, Brasil, 2003-2010 / Prevalence of Kaposi's sarcoma in patients with AIDS and associated factors, São Paulo-SP, Brazil, 2003-2010

OBJECTIVE: to estimate the prevalence of Kaposi's sarcoma (KS) in patients with AIDS and identify the associated factors to the occurrence of this neoplasm. METHODS: this is a cross-sectional study with notification data from two AIDS reference centers in São Paulo-SP, Brazil, from January, 2003 to March, 2010; probabilistic linkage and multiple logistic regression methods were applied. RESULTS: among 3,557 AIDS cases, 213 (6%) presented KS; 95.3% of them occurred in males; male sex (OR=3.1; 95%CI=1.4;6.6), age at the AIDS diagnosis >28 years old (OR=1.6; 95%CI=1.0;2.6), MSM (OR=3.2; 95%CI=2.0;4.9), prior use of HAART (OR=0.4; 95%CI=0.3;0.5), AIDS diagnosis between 2007-2010 (OR=0.3; 95%CI=0.2;0.4), and CD4+ T-cell counting under 200cells/mm3 (OR=16.0; 95%CI=6.0;42.7) and 200-500cells/mm³ (OR=2,5; 95%CI=1.1;6.4) were associated to the occurrence of KS. CONCLUSION: KS has a high prevalence in São Paulo-SP; strategies for early HIV diagnosis may reduce this prevalence.

Clinical and epidemiological characteristics associated with unfavorable tuberculosis treatment outcomes in TB-HIV co-infected patients in Brazil: a hierarchical polytomous analysis

Abstract Background: TB patients co-infected with HIV have worse treatment outcomes than non-coinfected patients. How clinical characteristics of TB and socioeconomic characteristics influence these outcomes is poorly understood. Here, we use polytomous regression analysis to identify clinical and epidemiological characteristics associated with unfavorable treatment outcomes among TB-HIV co-infected patients in Brazil. Methods: TB-HIV cases reported in the Brazilian information system (SINAN) between January 1, 2001 and December 31, 2011 were identified and categorized by TB treatment outcome (cure, default, death, and development of MDR TB). We modeled treatment outcome as a function of clinical characteristics of TB and patient socioeconomic characteristics by polytomous regression analysis. For each treatment outcome, we used cure as the reference outcome. Results: Between 2001 and 2011, 990,017 cases of TB were reported in SINAN, of which 93,147 (9.4%) were HIV co-infected. Patients aged 15–19 (OR = 2.86; 95% CI: 2.09–3.91) and 20–39 years old (OR = 2.30; 95% CI: 1.81–2.92) were more likely to default on TB treatment than those aged 0–14 years old. In contrast, patients aged ≥60 years were more likely to die from TB (OR = 2.22; 95% CI: 1.43–3.44) or other causes (OR = 2.86; 95% CI: 2.14–3.83). Black patients were more likely to default on TB treatment (OR = 1.33; 95% CI: 1.22–1.44) and die from TB (OR = 1.50; 95% CI: 1.29–1.74). Finally, alcoholism was associated with all unfavorable outcomes: default (OR = 1.94; 95% CI: 1.73–2.17), death due to TB (OR = 1.46; 95% CI: 1.25–1.71), death due to other causes (OR = 1.38; 95% CI: 1.21–1.57) and MDR-TB (OR = 2.29; 95% CI: 1.46–3.58). Conclusions: Socio-economic vulnerability has a significant effect on treatment outcomes among TB-HIV co-infected patients in Brazil. Enhancing social support, incorporation of alcohol abuse screening and counseling into current TB surveillance programs and targeting interventions to specific age groups are interventions that could improve treatment outcomes.

Survival of HIV patients with tuberculosis started on simultaneous or deferred HAART in the THRio cohort, Rio de Janeiro, Brazil

Background: The timing of highly active antiretroviral therapy (HAART) after a tuberculosis diagnosis in HIV-infected patients can affect clinical outcomes and survival. We compared survival after tuberculosis diagnosis in HIV-infected adults who initiated HAART and tuberculosis therapy simultaneously to those who delayed the start of HAART for at least two months. Methods: The THRio cohort includes 17,983 patients receiving HIV care in 29 public clinics in Rio de Janeiro, Brazil. HAART-naïve patients at the time of a new TB diagnosis between September 2003 and June 2008 were included. Survival was measured in days from diagnosis of TB. We compared survival among patients who initiated HAART within 60 days of TB treatment (simultaneous – ST) to those who started HAART >60 days of TB treatment or never started (deferred – DT). Kaplan–Meier plots and Cox proportional hazards regression analyses were conducted. Results: Of 947 patients diagnosed with TB, 572 (60%) were HAART naïve at the time of TB diagnosis; 135 were excluded because of missing CD4 count results. Among the remaining 437 TB patients, 56 (13%) died during follow-up: 25 (10%) among ST patients and 31 (16%) in DT group (p = 0.08). ST patients had lower median CD4 counts at TB diagnosis than DT patients (106 vs. 278, p < 0.001). Cox proportional hazards utilizing propensity score analysis showed that DT patients were more likely to die (adjusted HR = 1.89; 95% CI: 1.05–3.40; p = 0.03). Conclusion: HAART administered simultaneously with TB therapy was associated with improved survival after TB diagnosis. HAART should be given to patients with HIV-related TB as soon as clinically feasible. .

An evaluation of p16INK4a expression in cervical intraepithelial neoplasia specimens, including women with HIV-1

Although several studies have evaluated the role of p16INK4a as a diagnostic marker of cervical intraepithelial neoplasia (CIN) and its association with disease progression, studies regarding the role of p16INK4a in human immunodeficiency virus (HIV)-infected patients remain scarce. The present study was designed to determine the potential utility of p16INK4a as a diagnostic marker for CIN and invasive cervical cancer in HIV-positive and negative cervical specimens. An immunohistochemical analysis of p16INK4a was performed in 326 cervical tissue microarray specimens. Performance indicators were calculated and compared using receiving operating characteristics curve (ROC)/area under the curve. In HIV-1-negative women, the percentage of cells that was positive for p16INK4a expression was significantly correlated with the severity of CIN (p < 0.0001). A ROC curve with a cut-off value of 55.28% resulted in a sensitivity of 89%, a specificity of 81%, a positive predictive value of 91% and a negative predictive value of 78%. HIV-seropositive women exhibited decreased expression of p16INK4a in CIN2-3 specimens compared with HIV-negative specimens (p = 0.031). The ROC data underscore the potential utility of p16INK4a under defined conditions as a diagnostic marker for CIN 2-3 staging and invasive cervical cancer. HIV-1 infection, however, is associated with relatively reduced p16INK4a expression in CIN 2-3.

Behavior assessment of women attending a sexually transmitted disease clinic in Vitória, Brazil / Práticas comportamentais em mulheres atendidas em clínica de doenças sexualmente transmissíveis em Vitória, Brasil

BACKGROUND: Studies about sexual risk behaviors can provide information to support design strategies to control the spread of HIV infection. OBJECTIVE: To assess sexual risk behaviors among women attending a sexually transmitted diseases clinic in Vitória, Brazil. METHODS: A cross-sectional study was performed among women attending an STD/AIDS reference center. Enrolled participants were interviewed and provided a blood sample to determine HIV status. RESULTS: A total of 276 women participated. among 284 selected; 109 (39.5%) were HIV-positive and 167 (60.5%) HIV-negative. Median age was 31 years (interquartile range (IQR)24-36) and 69% of women were between 18 and 34 years of age. Women reported high access to information about STD (87%) and AIDS (90%) but information about sexuality was less common (55%). HIV-positive women asked their partners to use condoms more often than HIV-negatives (31% vs. 5%, p=0.02), and were more likely to have used a condom at last intercourse (65% vs. 33%, p<0.01). Among all patients, questions regarding risk of HIV transmission through sexual intercourse (99.6%) and needle sharing (99.2%) were most frequently answered correctly, while questions regarding risk of HIV transmission through blood donation (57%) were least. CONCLUSION: Though this population reports easy access to information and services for HIV/sexually transmitted diseases, most report little understanding of unsafe sexual behaviors, particularly HIV-negative women.

FUNDAMENTOS: Estudos sobre comportamentos sexuais de risco fornecem informações para programar estratégias para o controle da expansão da infecção pelo HIV/AIDS. OBJETIVO: Avaliar os comportamentos de risco sexual entre mulheres atendidas em clínica de doenças sexualmente transmissíveis em Vitória, Brazil. MÉTODOS: Estudo de corte-transversal foi realizado com mulheres atendidas no Centro de Referência para DST/Aids. As pacientes selecionadas foram entrevistadas e autorizaram a coleta de uma amostra de sangue para determinar sorologia para HIV. RESULTADOS: Um total de 276 mulheres participou, entre as 284 selecionadas; 109 (39,5%) eram HIV-positivas e 167 (60,5%) HIV-negativas. A mediana de idade foi 31 anos (distância interquartil 24-36) e 69% das mulheres tinham entre 18 e 34 anos de idade. As mulheres relataram alto grau de acesso a informações sobre doenças sexualmente transmissíveis (87%) e Aids (90%), mas as informações sobre saúde sexual foram menos comuns (55%). Mulheres HIV-positivas pediram a seus parceiros para usar preservativos mais comumente do que as HIV-negativas (31% vs. 5%, p=0,02), e relataram com maior frequência o uso do preservativo na ultima relação sexual (65% vs. 33%, p<0,01). Entre todas as pacientes, questões sobre o risco da transmissão de HIV através da relação sexual (99,6%) e compartilhar agulhas durante uso de drogas (99,2%) foram mais frequentemente respondidas de forma correta, enquanto que questões relacionadas ao risco de HIV através da doação de sangue (57%) foi menor. CONCLUSÕES: Apesar desta população relatar fácil acesso aos serviços e informações sobre doenças sexualmente transmissíveis/Aids, a maioria relatou entendimento inadequado sobre comportamentos sexuais inseguros, particularmente as mulheres HIV-negativas.

Physician adherence to guidelines for tuberculosis and HIV care in Rio de Janeiro, Brazil

BACKGROUND: Tuberculosis is the most common opportunistic infection among HIV-infected patients in Brazil. Brazil's national policy for HIV care recommends screening for latent tuberculosis (TB) and implementing isoniazid preventive therapy (IPT). OBJECTIVES: We compared physician adherence to TB screening and other prevention and care policies among HIV primary care clinics in Rio de Janeiro City. METHODS: Data on performance of CD4 counts, viral load testing, tuberculin skin testing (TST) and IPT were abstracted from patient charts at 29 HIV clinics in Rio de Janeiro as part of the TB/HIV in Rio (THRio) study. Data on use of pneumocystis jiroveci pneumonia (PCP) prophylaxis were also abstracted from a convenience sample of 150 patient charts at 10 HIV clinics. Comparisons were made between rates of adherence to TB guidelines and other HIV care guidelines. RESULTS: Among the subset of 150 patients with confirmed HIV infection in 2003, 96 percent had at least one reported CD4 counts result; 93 percent had at least one viral load result reported; and, PCP prophylaxis was prescribed for 97 percent of patients with CD4 counts < 200 cells/mm³ or when clinically indicated. In contrast, 67 patients (45 percent) had a TST performed (all eligible); and only 11 percent (17) of eligible patients started IPT. Among 12,027 THRio cohort participants between 2003 and 2005, the mean number of CD4 counts and viral load counts was 2.5 and 1.9, respectively, per patient per year. In contrast, 49 percent of 8,703 eligible patients in THRio had a TST ever performed and only 53 percent of eligible patients started IPT. CONCLUSION: Physicians are substantially more compliant with HIV monitoring and PCP prophylaxis than with TB prophylaxis guidelines. Efforts to improve TB control in HIV patients are badly needed.

Cost-effectiveness of community health worker versus home-based guardians for directly observed treatment of tuberculosis in Vitória, Espírito Santo State, Brazil / Custo-efetividade dos agentes comunitários de saúde versus supervisores domiciliares na realização do tratamento supervisionado da tuberculose, Vitória, Espírito Santo, Brasil

The objective of this study was to compare the costs and outcomes associated with guardian-supervised directly observed treatment relative to the standard of care Directly Observed Therapy, Short Course (DOTS) provided by community health workers (CHW). New cases of culture-positive pulmonary tuberculosis (TB) treated in Vitória, Espírito Santo State, Brazil, between January 2005 and December 2006 were interviewed and chose their preferred treatment strategy. Costs incurred by providers and patients (and patients' families) were estimated, and cost-effectiveness was assessed by comparing costs per successfully treated patient. 130 patients were included in the study; 84 chose CHW-supervised DOTS and 46 chose guardian-supervised DOTS. 45 of 46 (98 percent) patients treated with guardian-supervised DOTS were cured or completed treatment compared to 70/84 (83 percent) of the CHW-supervised patients (p = 0.01). Logistic regression showed only the strategy of supervision to be a significant association with treatment outcome, with guardian-supervised care strongly protective. Cost per patient treated with guardian-supervised DOTS was US$398, compared to US$548 for CHW-supervised DOTS. The guardian-supervised DOTS is an attractive option to complement CHW-supervised DOTS.

Comparar os custos e os resultados associados ao tratamento de tuberculose (TB) supervisionado por domiciliares quanto ao realizado pelos agentes comunitários de saúde (ACS). Participaram do estudo todos os casos de TB pulmonar com cultura positiva tratada na cidade de Vitória, Espírito Santo, Brasil, entre janeiro de 2005 e dezembro de 2006. Os pacientes escolheram a estratégia de tratamento preferencial. Os custos incorridos pelos prestadores e os doentes foram estimados, e relação custo-efetividade foi avaliada comparando os custos por doente tratado com sucesso. Um total de 130 pacientes foi incluído no estudo, 84 escolheram ACS e 46 escolheram tratamento supervisionado por domiciliares. 45 de 46 (98 por cento) dos doentes tratados com supervisionamento por domiciliares foram curados ou tratamento completado em comparação com 70/84 (83 por cento) dos pacientes ACS (p = 0,01). Regressão logística mostrou o tratamento supervisionado por domiciliares significativamente protetor em relação ao abandono do tratamento da TB ao realizado pelo ACS. Custo por paciente tratado com o tratamento supervisionado por domiciliares foi de US$ 398, em comparação com US$ 548 para ACS. Tratamento supervisionado por domiciliares é uma opção mais custo-efetividade do que a supervisão pelo ACS.

Perfil epidemiológico de pacientes adultos com tuberculose e AIDS no estado do Espírito Santo, Brasil: relacionamento dos bancos de dados de tuberculose e AIDS / Epidemiological profile of adult patients with tuberculosis and AIDS in the state of Espírito Santo, Brazil: cross-referencing tuberculosis and AIDS databases

OBJETIVO: Avaliar o perfil epidemiológico de pacientes com tuberculose (TB) e daqueles com TB e HIV no estado do Espírito Santo entre 2000 e 2006. MÉTODOS: Coletamos dados demográficos e clínicos dos pacientes de interesse do Centro de Vigilância Epidemiológica do Estado do Espírito Santo (banco de dados para TB), do Sistema de Informação de Agravos de Notificação, do Sistema de Informação sobre Mortalidade, do Sistema de Controle de Exames Laboratoriais da Rede Nacional de Contagem de Linfócitos CD4+/CD8+ e Carga Viral e do Sistema de Controle Logístico de Medicamentos (bancos de dados para HIV/AIDS). Todos os dados compilados foram cruzados. RESULTADOS: Durante o período do estudo, 9.543 pacientes com TB > 15 anos de idade foram identificados, dos quais 437 (4,6 por cento) tinham HIV. A mediana de idade não diferiu entre os pacientes com TB/AIDS e somente com TB (35 anos vs. 38 anos). Dos 437 pacientes com TB/AIDS, 298 (68,2 por cento) eram homens, e 156 (35,8 por cento) estavam na faixa etária de 30-39 anos. Quanto ao desfecho do tratamento da TB, 79,0 por cento foram curados, 9,7 por cento foram transferidos para outros locais, 6,0 por cento foram a óbito, 5,2 por cento abandonaram o tratamento, e 0,2 por cento desenvolveram TB multirresistente. O óbito foi 4,75 vezes mais comum nos pacientes com TB/AIDS do que naqueles somente com TB. A TB pulmonar representou 82,4 por cento dos casos. A combinação de TB pulmonar e extrapulmonar foi 8,2 vezes mais frequente nos pacientes com TB/AIDS do que naqueles somente com TB (IC95 por cento: 6,2-10,8). CONCLUSÕES: Nossos resultados enfatizam a significância da AIDS em pacientes com TB no Brasil, assim como a importância de se avaliar dados secundários a fim de melhorar a sua qualidade e desenvolver intervenções de saúde pública.

OBJECTIVE: To evaluate the epidemiological profile of patients with tuberculosis (TB) only and that of patients with TB/AIDS in the state of Espírito Santo, Brazil, between 2000 and 2006. METHODS: For the patients of interest, we collected demographic and clinical data from the Epidemiological Surveillance Center (TB database), Brazilian Case Registry Database, and Brazilian National Mortality Database, as well as the Brazilian National CD4+/CD8+ T Lymphocyte Count and Viral Load Network Laboratory Test Control System and the Logistic Medication Monitoring System (HIV/AIDS databases). All of the compiled data were cross-referenced. RESULTS: During the study period, we identified 9,543 TB patients > 15 years of age, 437 of whom (4.6 percent) had AIDS. The median age did not differ between TB/AIDS and TB-only patients (35 years vs. 38 years). Of the 437 TB/AIDS patients, 298 (68.2 percent) were male, and 156 (35.8 percent) were in the 30-39 age bracket. In terms of TB treatment outcome, 79.0 percent were cured, 9.7 percent were referred to other facilities, 6.0 percent died, 5.2 percent abandoned treatment, and 0.2 percent developed multidrug-resistant TB. Death was 4.75 times more common in patients with TB/AIDS than in those with TB only. Pulmonary TB accounted for 82.4 percent of the cases. The combination of pulmonary and extrapulmonary TB was 8.2 times more common in the TB/AIDS patients than in the TB-only patients (95 percent CI: 6.2-10.8). CONCLUSIONS: Our results emphasize the significance of AIDS among TB patients in Brazil, as well as the importance of evaluating secondary data in order to improve their quality and develop public health interventions.

Prevalence of patients with respiratory symptoms through active case finding and diagnosis of pulmonary tuberculosis among prisoners and related predictors in a jail in the city of Carapicuíba, Brazil / Prevalência de sintomáticos respiratórios através da busca ativa, diagnóstico de tuberculose pulmonar entre pessoas privadas de liberdade e fatores associados em uma cadeia pública no município de Carapicuíba, Brasil

BACKGROUND: Prisons offer a fertile setting for the transmission of tuberculosis due to the presence of many classic risk factors for both infection and disease: overcrowding, poor ventilation, and little sunlight. Prisoners are often malnourished and have poor hygiene and are more likely to have a background of alcohol and drug abuse. OBJECTIVES: To determine the prevalence of prisoners with respiratory symptoms and pulmonary tuberculosis (PTB) through active case finding in a prisoner population of the county jail of Carapicuíba, and to study possible related variables. METHODS: This was a cross-sectional study, and respiratory symptomatic individuals (RSI) were detected through active case finding. Socio-demographic data were collected from inmates' judicial history using a specific questionnaire. The RSI provided sputum specimens for detection of acid fast bacilli and culture for mycobacterium identification. RESULTS: Among the 397 prisoners studied, 154 reported respiratory symptoms for more than three weeks, and were considered RSI; the variables associated with RSI were: having already been tried and incarcerated for more than six months and seven were diagnosed as PTB (1,763 cases/ 100,000 inhabitants). CONCLUSIONS: The prevalence of RSI and PTB cases were respectively 39 and 35 times greater than the general population.

INTRODUÇÃO: Estabelecimentos prisionais são um campo favorável para a transmissão de tuberculose (TB), devido a presença de vários fatores de risco clássicos, tanto para a infecção como para a doença: aglomeração, falta de ventilação e de iluminação, como também o fato de os detentos receberem uma nutrição deficitária e os locais possuí-rem condições de higiene precárias; uma grande proporção dos detentos apresentam história pregressa de alcoolismo e uso de drogas ilícitas nas dependências desses estabelecimentos. OBJETIVOS: Determinar a prevalência de sintomáticos respiratórios (RSI) e casos de tuberculose pulmonar (TBP) através da busca ativa em população privada de liberdade na cadeia pública do município de Carapicuíba e estudar os prováveis fatores associados. MÉTODO: O desenho de estudo foi do tipo corte transversal, realizou-se a busca ativa de RSI e os dados sociodemográficos foram coletados em questionários específicos a partir dos processos judiciais dos participantes. Os RSI foram submetidos ao exame de baciloscopia e cultura para micobactérias do escarro. RESULTADOS: Dos 397 detentos estudados, 154 relataram tosse por mais de três semanas, considerados RSI. Os fatores associados à presença de sintomas respiratórios foram estar preso há mais de seis meses e ter sido julgado. Foram diagnosticados 7 casos de tuberculose pulmonar, 1.763 casos por 100.000 detentos. CONCLUSÕES: A prevalência de RSI e casos de TBP foram 39 e 35 vezes superior ao encontrado na população em geral respectivamente.

Tuberculosis and AIDS co-morbidity in Brazil: linkage of the tuberculosis and AIDS databases

This study evaluated differences in AIDS patients with and without tuberculosis (TB) in Espírito Santo State, Brazil. Standard regional AIDS (SINAN, SISCEL, SICLOM and SIM) and tuberculosis (SINAN) databases were used. TB and AIDS databases were linked using Reclink software, version 3, with SPSS software support to identify co-infected cases. Data from July 2000 to June 2006 in Espírito Santo State were linked. The results showed 3,523 adult AIDS cases and 9,958 adult TB cases resulted in 430 co-infected patients, who were compared to 1,290 AIDS patients who never developed TB. Among 430 co-infected patients, TB was diagnosed first in 223 (51.9 percent), AIDS was first in 44 (10.2 percent), and AIDS and TB were diagnosed concurrently in 163 (37.9 percent). Median age did not differ between co-infected cases (36 years (interquartile range [IQR] 29-43) and non-co-infected cases (34 years; IQR 28-42). Pulmonary tuberculosis was diagnosed in 239 (55.6 percent); 109 (25.3 percent) had extra-pulmonary TB and 82 (19.1 percent) had both presentations. In the final logistic regression model, living in a metropolitan area [Odds Ratio (OR)=1.43 (95 percent Confidence Interval (CI) 1.05-1.95)], education < 3 years [OR=3.03 (95 percentCI 1.56-5.88)] and CD4 counts < 200/mm³ [OR=1.14 (95 percentCI 1.09-1.18)] were associated with co-infection. This report emphasizes the significance of tuberculosis among AIDS cases in Brazil, and highlights the importance of evaluating secondary data for purposes of improving data quality and developing public health interventions.
