RESUMO

BACKGROUND: Sexually transmitted infections (STI) can have severe consequences. In Brazil, case management is recommended by the Clinical Protocol and Therapeutical Guidelines for Comprehensive Care for People with STIs (PCDT-IST). This study assessed the quality of PCDT-IST (2021) and reviewed the main recommendations for the management of STI that cause urethral discharge compared with the World Health Organization (WHO) STI Guidelines. METHODS: The PCDT-IST (2021) quality was independently assessed by 4 appraisers using the Appraisal of Guidelines Research and Evaluation instrument, version II (AGREE II). The PCDT-IST (2021) and the WHO Guidelines for the Management of Symptomatic STI (2021) were compared considering 14 different assessment domains. RESULTS: The PCDT-IST (2021) scores in the AGREE II domains were: Rigor of Development (58%), Applicability (35%), Editorial Independence (38%), Scope and Purpose (78%), Stakeholder Involvement (74%), and Clarity and Presentation (82%). The overall score was 67%, and all appraisers recommended the Brazilian guideline. Regarding the PCDT-IST (2021) and the WHO STI Guidelines (2021) comparation, 10 domains would be relevant for further reviewing the Brazilian recommendations: Diagnostic tests; Etiological approach; Treatment for recurrent urethral discharge; Treatment for urethritis without etiological agent identification; Treatment for gonococcal urethritis; Treatment for chlamydial urethritis; Retreatment for gonococcal infections; Treatment for Mycoplasma genitalium urethritis; Treatment for Trichomonas vaginalis urethritis; 10. Flowcharts. CONCLUSIONS: The PCDT-IST (2021) has a reasonable degree of quality. However, the domains of Applicability, Rigor of Development, and Editorial Independence must be better ensured. The guidelines comparison will help to select key topics that should be addressed with priority in the following national STI guidelines updates.

RESUMO

We field-assessed the accuracy, acceptability, and feasibility of the SD BIOLINE HIV/Syphilis Duo rapid diagnostic test in three groups: pregnant women, female sex workers (FSW), and men who have sex with men (MSM). Venous blood samples collected in the field were compared with the respective gold standard methods: SD BIOLINE HIV/Syphilis Duo Treponemal Test versus FTA-abs (Wama brand) treponemal laboratory test for syphilis, and SD BIOLINE HIV/Syphilis Duo Test versus the fourth generation Genscreen Ultra HIV Ag-Ag (Bio-Rad brand) laboratory test for HIV. From a total of 529 participants, 397 (75.1%) were pregnant women, 76 (14.3%) FSW and 56 (10.6%) MSM. Sensitivity and specificity parameters of HIV were 100.0% (95% CI: 82.35-100.0%) and 100.0% (95% CI: 99.28-100.0%), respectively. Sensitivity and specificity parameters found for TP antibody detection were 95.00% (95% CI: 87.69-98.62%) and 100.0% (95% CI: 98.18-100.0%), respectively. The SD BIOLINE HIV/Syphilis Duo Test showed high acceptability among participants (85.87%) and health professionals (85.51%), as well as easy usability by professionals (91.06%). The usability of the SD BIOLINE HIV/Syphilis Duo Test kit would not be a barrier to accessing rapid testing, if the product were incorporated into the list of health service supplies.

RESUMO

Abstract: To assess the adequacy of prenatal care offered in the Brazilian capital cities and the diagnosis of gestational syphilis through public data from health information systems. The modified Kotelchuck index for adequacy of prenatal care was built using Brazilian Information System on Live Births (SINASC) data. Data on gestational syphilis, congenital syphilis, estimated population coverage by the Family Health Strategy (FHS), the Municipal Human Development Index (MHDI) and data from National Program for Access and Quality Improvement in Primary Care (PMAQ-AB) were accessed in public sites. The profile of pregnant women associated with inadequate care was assessed by logistic regression. In total, 685,286 births were analyzed. Only 2.3% of women did not attend prenatal appointments. The mean adequacy was 79.7%. No correlation was found between adequacy of prenatal care and FHS coverage (p = 0.172), but a positive correlation was found with the MHDI (p < 0.001). Inadequacy of prenatal care was associated with age below 20 years old, schooling less than 4 years, non-white skin color and not having a partner. Among the congenital syphilis cases, 17.2% of mothers did not attend prenatal care. Gestational syphilis more often affected vulnerable women, including a higher proportion of adolescents, women with low schooling, and women of non-white color. The PMAQ-AB showed a median availability of 27.3% for syphilis rapid tests, 67.7% for benzathine penicillin, and 86.7% for benzathine penicillin administration by health teams. The use of public data showed a low adequacy of prenatal care in Brazilian capitals, denoting insufficient quality for the diagnosis and treatment of gestational syphilis, despite the availability of supplies. Continuous monitoring can be carried out using public data, indicating to local strategies to eliminate congenital syphilis.


Resumo: O estudo buscou avaliar a adequação do atendimento pré-natal oferecido nas capitais brasileiras e o diagnóstico da sífilis gestacional através de dados públicos dos sistemas de informação de saúde. Foi construído o indicador de Kotelchuck modificado para adequação do atendimento pré-natal, usando dados do Sistema de Informações sobre Nascidos Vivos (SINASC). Foram acessados em sites públicos os dados sobre sífilis gestacional, sífilis congênita, estimativa da cobertura populacional pela Estratégia Saúde da Família (ESF), Índice de Desenvolvimento Humano (IDH) municipal e dados do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB). O perfil das gestantes associado ao atendimento inadequado foi avaliado com base na regressão logística. Foram analisados um total de 685.286 nascimentos. Apenas 2,3% das mulheres não receberam atendimento pré-natal. A taxa média de adequação foi de 79,7%. Não foi encontrada correlação entre a adequação do pré-natal e a cobertura pela ESF (p = 0,172), mas houve correlação com o IDH municipal (p < 0,001). A inadequação da assistência pré-natal mostrou associação com a idade < 20 anos, escolaridade < 4 anos, raça/cor não-branca e situação conjugal sem companheiro. Entre os casos de sífilis congênita, 17,2% das mães não haviam recebido atendimento pré-natal, e a sífilis gestacional afetava mais as gestantes vulneráveis, incluindo uma proporção maior de adolescentes, mulheres com baixa escolaridade e mulheres não brancas. O PMAQ-AB mostrou uma disponibilidade mediana de 27,3% de testes rápidos para sífilis, 67,7% para penicilina benzatina e 86,7% para administração de penicilina benzatina pela equipe de saúde. O uso de dados públicos revelou baixa adequação do atendimento pré-natal nas capitais brasileiras, denotando qualidade insuficiente para o diagnóstico e tratamento da sífilis gestacional, apesar da disponibilidade de insumos. O monitoramento contínuo pode ser realizado com o uso de dados públicos, indicando estratégias locais para eliminar a sífilis congênita.


Resumen: El objetivo de este trabajo ha sido evaluar la adecuación de la atención prenatal que se ofreció en capitales brasileñas, y el diagnóstico de sífilis gestacional, mediante datos públicos de los sistemas de información de salud. El indicador modificado de Kotelchuck para la adecuación de la atención prenatal se construyó usando datos del Sistema de Información sobre Nacidos Vivos (SINASC). La información sobre sífilis gestacional, sífilis congénita, así como la cobertura de población estimada por la Estrategia Salud de Familia (ESF), Índice de Desarrollo Humano (IDH) municipal y datos del Programa Nacional para el Acceso Mejorado y Calidad de la Atención Básica (PMAQ-AB) se recabaron de sitios web públicos. El perfil de las mujeres embarazadas asociado con el cuidado inadecuado fue evaluado mediante regresión logística. En total, se analizaron 685.286 nacimientos. Solamente un 2,3% de las mujeres no atendieron a citas prenatales. La adecuación media fue de un 79,7%. No se encontró correlación entre la adecuación del cuidado prenatal y la cobertura de la ESF (p = 0,172), pero se encontró una correlación positiva con el MHDI (p < 0,001). La inadecuación del cuidado prenatal estuvo asociada con una edad < 20 años, escolaridad < 4 años, raza no blanca y no tener pareja. Entre los casos de sífilis congénita, un 17,2% de las madres no asistieron a la atención prenatal. La sífilis gestacional afectó más a menudo a las mujeres vulnerables, incluyendo una más alta proporción de adolescentes, mujeres con baja escolaridad, y mujeres de color no blanco. La PMAQ-AB mostró un promedio de disponibilidad de un 27,3%, en el caso de test rápidos de sífilis, un 67,7% para la penicilina benzatínica, y un 86,7% para la administración penicilina benzatínica por equipos de salud. El uso de los datos públicos mostró una baja adecuación del cuidado prenatal en capitales brasileñas, denotando una insuficiente calidad para el diagnóstico y tratamiento de la sífilis gestacional, a pesar de la disponibilidad de suministros. La supervisión continua se puede llevar a cabo usando datos públicos, apuntando a estrategias locales para eliminar la sífilis congénita.

RESUMO

BACKGROUND: The introduction of highly effective direct-acting antiviral (DAA) therapy for hepatitis C has led to calls to eliminate it as a public health threat through treatment-as-prevention. Recent studies suggest it is possible to develop a vaccine to prevent hepatitis C. Using a mathematical model, we examined the potential impact of a hepatitis C vaccine on the feasibility and cost of achieving the global WHO elimination target of an 80% reduction in incidence by 2030 in the era of DAA treatment. METHODS: The model was calibrated to 167 countries and included two population groups (people who inject drugs (PWID) and the general community), features of the care cascade, and the coverage of health systems to deliver services. Projections were made for 2018-2030. RESULTS: The optimal incidence reduction strategy was to implement test and treat programmes among PWID, and in settings with high levels of community transmission undertake screening and treatment of the general population. With a vaccine available, the optimal strategy was to include vaccination within test and treat programmes, in addition to vaccinating adolescents in settings with high levels of community transmission. Of the 167 countries modelled, between 0 and 48 could achieve an 80% reduction in incidence without a vaccine. This increased to 15-113 countries if a 75% efficacious vaccine with a 10-year duration of protection were available. If a vaccination course cost US$200, vaccine use reduced the cost of elimination for 66 countries (40%) by an aggregate of US$7.4 (US$6.6-8.2) billion. For a US$50 per course vaccine, this increased to a US$9.8 (US$8.7-10.8) billion cost reduction across 78 countries (47%). CONCLUSIONS: These findings strongly support the case for hepatitis C vaccine development as an urgent public health need, to ensure hepatitis C elimination is achievable and at substantially reduced costs for a majority of countries.

RESUMO

ABSTRACT Introduction and aim: Hepatitis C is a key challenge to public health in Brazil. The objective of this paper was to describe the Brazilian strategy for hepatitis C to meet the 2030 elimination goal proposed by World Health Organization (WHO). Methods: A mathematical modeling approach was used to estimate the current HCV-infected Brazilian population, and to evaluate the relative costs of two different scenarios to address HCV disease burden in Brazil: (1) if no further changes are made to the HCV treatment program in Brazil; (2) where the WHO targets for 2030 elimination are met through diagnosis and treatment efforts peaking before 2024. Results: An anti-HCV prevalence of 0.53% was calculated for the total population. It was estimated that the number of HCV-RNA+ individuals in Brazil in 2017 was 632,000 (0.31% of the population). Scale-up of treatment and diagnosis over time will be necessary in order to achieve WHO targets beginning in 2018. Direct costs (diagnostic, treatment and healthcare costs) are projected to increase significantly during the scale-up of treatment and diagnosis in the initial years of the intervention scenario, but then fall below the base case on an annual basis by 2025-2036, once HCV is eliminated, due to health sectors savings from the prevention of HCV liver-related morbidity and mortality. Conclusion: Achieving the WHO targets is technically feasible in Brazil with a scale-up of treatment and diagnosis over time, beginning in 2018. However, elimination of hepatitis C requires policy changes to substantially scale-up prevention, screening and treatment of HCV, together with public health advocacy to raise awareness among affected populations and healthcare providers.

RESUMO

The National Network for CD4+ T-lymphocyte counting of Brazil comprises 93 laboratories. This study reports the laboratory performances achieved in external quality assessment (EQA) rounds provides by Ministry of Health to evaluate the quality of the kits used and the performance of test by the technicians.Ten EQA rounds were analyzed according the EQA criteria aimed to evaluate individual laboratory performance on the basis of the accuracy of their results compared to the general mean obtained by all participating laboratories and the reproducibility of the results obtained between 2 samples from the same donor.The percentage of approved and failed laboratories in the EQAs tends to follow a uniform pattern. Since 2011, approval has remained above 80% and the failure rate has never exceeded 15%.EQA is very important to evaluate the performance of the laboratories, to identify monitor, and to resolve errors as quickly as possible.

RESUMO

PURPOSE: To improve the screening of Chlamydia trachomatis(C. trachomatis) in Brazil, an accurate and affordable method is needed. The objective of this study was to develop and assess the performance and costs of a new in-house real-time PCR (qPCR) assay for the diagnosis of C. trachomatis infection. METHODOLOGY: Asymptomatic women aged 14-25 years who attended primary health services in Manaus, Brazil, were screened for C. trachomatis using the Digene Hybrid Capture II CT-ID (HCII CT-ID) DNA test. A subset of cervical specimens were tested using an in-house qPCR and a commercial qPCR, ArtusC. trachomatis Plus RG PCR 96 CE (Artus qPCR) kit, as a reference test. A primer/probe based on the sequence of cryptic plasmid (CP) was designed. An economic evaluation was conducted from the provider's perspective. RESULTS: The primers were considered specific for C. trachomatis because they did not amplify any product from non-sexually transmitted bacterial species tested. Overall, 292 specimens were tested by both the commercial kit (Artus qPCR) and the in-house qPCR. Of those, one resulted in no amplification and was excluded from the analysis. The sensitivity, specificity, and positive and negative predictive values of the in-house qPCR were 99.5 % [95 % confidence interval (CI): 97.1-100], 95.1 % (95 % CI: 89-98.4), 97.4 % (95 % CI: 94-99.1) and 99.0 % (95 % CI: 94.5-100), respectively. The cost per case of C. trachomatis was £0.44 ($0.55) for HCII CT-ID, £1.16 ($1.45) for Artus qPCR and £1.06 ($1.33) for in-house qPCR. CONCLUSION: We have standardized an in-house qPCR to detect cervical C. trachomatis targeting CP. The in-house qPCR showed excellent accuracy and was more affordable than the commercial qPCR kit.

RESUMO

Abstract: Screening for Chlamydia trachomatis is not routinely offered to young asymptomatic women in Brazil. This study evaluated the performance, usefulness, and operational suitability of the Digene Hybrid Capture II (HCII) CT-ID DNA-test as an opportunistic screening tool to detect C. trachomatis in the public health system in Manaus, Amazonas State. Women aged 14-25 years who attended primary health care services were interviewed and one cervical specimen was collected during cytological screening. The HCII CT test was evaluated for its ability to detect the presence of C. trachomatis and against real-time PCR (q-PCR) in a subset of samples. Operational performance was assessed through interviews with providers and patients. Overall, 1,187 women were screened, and 1,169 had a HCII CT-ID test result (292 of these were also tested by q-PCR). Of those, 13.1% (n = 153) were positive. The sensitivity, specificity, positive and negative predictive values of HCII CT were 72.3% (95%CI: 65.4-78.6), 91.3% (95%CI: 84.1-95.9), 93.8% (95%CI: 88.5-97.1), and 64.4% (95%CI: 56.0-72.1), respectively. Sample collection caused discomfort in 19.7% of women. Among health professionals (n = 52), the main barriers reported included positive cases who did not return for results (56.4%), unwillingness to screen without an appointment (45.1%), and increase in their workload (38.8%). HCII CT-ID identified a high proportion of C. trachomatis cases among young women in Manaus. However, its moderate sensitivity limits its use as an opportunistic screening tool in primary health care settings in Manaus. Screening was well accepted although the barriers we identified, especially among health professionals, challenge screening detection and treatment efforts.


Resumo: O rastreamento de Chlamydia trachomatis não é feito de rotina em mulheres jovens assintomáticas no Brasil. O estudo avaliou o desempenho, utilidade e adequação operacional do teste de DNA Digene Hybrid Capture II (HCII) CT-ID como ferramenta de rastreamento oportunista para detectar C. trachomatis no sistema público de saúde em Manaus, Amazonas. Mulheres entre 14 e 25 anos de idade que frequentavam serviços de atenção básica foram entrevistadas, com a coleta de uma amostra cervicouterina durante o rastreamento citológico. O teste HCII CT foi avaliado em relação à capacidade de detectar a presença de C. trachomatis, e comparado à PCR em tempo real (q-PCR) em um sub-conjunto de amostras. O desempenho operacional foi avaliado através de entrevistas com profissionais e pacientes. Foram examinadas 1.187 mulheres, das quais 1.169 tiveram um resultado de teste HCII CT-ID (destas, 292 foram testadas também com q-PCR). Um total de 153 mulheres (13,1%) testaram positivas para C. trachomatis. A sensibilidade, especificidade e valores preditivos positivo e negativo do HCII CT foram 72,3% (IC95%: 65,4-78,6), 91,3% (IC95%: 84,1-95,9), 93,8% (IC95%: 88,5-97,1) e 64,4% (IC95%: 56,0-72,1), respectivamente. A coleta de amostras provocou desconforto em 19,7% das mulheres. As principais barreiras relatadas pelos profissionais de saúde (n = 52) eram casos positivos que não retornavam para os resultados (56,4%), falta de disponibilidade de realizar o rastreamento sem consulta agendada (45,1%) e aumento da carga de trabalho (38,8%). O HCII CT-ID identificou alta prevalência de C. trachomatis em mulheres jovens de Manaus. Entretanto, a sensibilidade moderada limita o uso como ferramenta de rastreamento oportunista em serviços de atenção básica naquela cidade. O rastreamento era bem-recebido, mas as barreiras identificadas, principalmente entre profissionais de saúde, limitam a detecção através do rastreamento e as iniciativas de tratamento.


Resumen: Los exámenes de control de Chlamydia trachomatis no se ofrecen habitualmente a las mujeres jóvenes asintomáticas en Brasil. Este estudio evaluó los resultados, utilidad e idoneidad operativa del test Digene Hybrid Capture II (HCII) CT-ID DNA como una herramienta de examen apropiada para detectar la C. trachomatis en el sistema de salud público de Manaus, Amazonas. Las mujeres con una edad comprendida entre los 14-25 años que asistieron a un centro de atención primaria fueron entrevistadas, y se recogió una muestra cervical durante el examen citológico. Se evaluó el test HCII CT, debido a su habilidad para detectar la presencia de C. trachomatis, frente al realtime PCR (q-PCR) en un subconjunto de muestras. El resultado operativo fue evaluado mediante entrevistas con proveedores y pacientes. Globalmente, se examinaron a 1.187 mujeres, y 1.169 de ellas contaban con los resultados de la prueba HCII CT-ID (a 292 de las cuales también se les aplicó el test q-PCR). Entre ellas, un 13,1% (n = 153) eran positivo. La sensibilidad, especificidad, los valores predictivos positivos y negativos del HCII CT fueron 72,3% (IC95%: 65,4-78,6), 91,3% (IC95%: 84,1-95,9), 93,8% (IC95%: 88,5-97,1), y 64,4% (IC95%: 56,0-72,1), respectivamente. La toma de muestras resultó incómoda en un 19,7% de las mujeres. Entre los profesionales de la salud (n = 52), las barreras principales informadas incluyeron casos positivos que no volvieron a recoger los resultados (56,4%), reticencia a realizarse el examen sin cita previa (45,1%), e incremento en su carga laboral (38,8%). El HCII CT-ID identificó un alto porcentaje de casos de C. trachomatis entre mujeres jóvenes en Manaus. No obstante, su moderada sensibilidad limita su uso como una herramienta idónea en los centros de atención primaria en Manaus. El examen fue bien aceptado, pese a que identificamos obstáculos, especialmente entre los profesionales de salud, lo que supone un desafío para la detección de la enfermedad que requiere esfuerzos para su tratamiento.

RESUMO

BACKGROUND: Point-of-care (POC) screening for HIV and syphilis using rapid testing was implemented in indigenous communities in the triple-border area of the Brazilian Amazon. We describe the context of the early introduction of POC screening, explore hindering and enabling factors for POC implementation, and recommend strategies for feasible, viable, and sustainable syphilis and HIV screening interventions. METHODS: This was a qualitative study based on grounded theory methodology. Data were collected using in-depth interviews, semi-structured questionnaires, and field observations and were analysed using the framework approach. Qualitative information was complemented by quantitative data for descriptive purposes. RESULTS: An overall high score for vulnerability to acquiring HIV and syphilis was observed among the indigenous communities. Health professionals reported satisfactory rapid testing acceptance, although concerns were raised about the pain of the fingerprick. Counselling-related challenges included ensuring the accuracy of translations, collaborating with translators and communicating positive test results. Over 3 months, 86.7% of the syphilis-positive individuals began treatment, and all of them notified their partners. Accessibility, measured as travel time via the local transportation network, was a barrier to health care access. A lack of gasoline for boats and other transportation was also a hindering factor at all levels of implementation. CONCLUSIONS: The recommendations address the preparation phase at the coordination level as well as at the training level. Tools such as strengths, weaknesses, opportunities, and threats (SWOT) analyses; checklists; context-adapted protocols; and fact sheets are very simple methods to facilitate implementation. The findings of this study are important because they may inform the implementation of new health technologies in low-resource national disease control programmes in remote communities.

RESUMO

INTRODUCTION: In 2011, the Brazilian Ministry of Health rolled out a program for the external quality assessment of rapid human immunodeficiency virus (HIV) tests using the dried tube specimen (DTS) method (EQA-RT/DTS-HIV). Our objective was to evaluate the implementation of this program at 71 voluntary counseling and testing centers (VCTCs) in the Brazilian Legal Amazonian area one year after its introduction. METHODS: Quantitative and qualitative study that analyzed secondary data and interviews with healthcare workers (HCWs) (n=39) and VCTC coordinators (n=32) were performed. The assessment used 18 key indicators to evaluate the three dimensions of the program's logical framework: structure, process, and result. Each indicator was scored from 1-4, and the aggregate results corresponding to the dimensions were expressed as proportions. The results were compared to the perceptions of the HCWs and coordinators regarding the EQA-RT/DTS-HIV program. RESULTS: The aggregate scores for the three dimensions of structure, process, and result were 91.7%, 78.6%, and 95%, respectively. The lowest score in each dimension corresponded to a different indicator: access to Quali-TR online system 39% (structure), registration in Quali-TR online system 38.7% (process), and VCTC completed the full process in the program's first round 63.4% (result). Approximately 36% of the HCWs and 52% of the coordinators reported enhanced trust in the program for its rapid HIV testing performance. CONCLUSIONS: All three program dimensions exhibited satisfactory results (>75%). Nevertheless, the study findings highlight the need to improve certain program components. Additionally, long-term follow-ups is needed to provide a more thorough picture of the process for external quality assessment.

RESUMO

OBJETIVO: Descrever estudo de caso de intervenção de base comunitária, desenvolvido na perspectiva construcionista-emancipatória, para o controle das DST/Aids. MÉTODOS: Estudo descritivo desenvolvido no município de Manacapuru, Amazonas, de 1997-2004, sobre a utilização de procedimentos desenhados em colaboração com agentes governamentais, profissionais de saúde e comunidade. Foram levantados dados sobre a dinâmica da prostituição e a venda de preservativos na cidade, características comportamentais, avaliação do processo e da assistência às DST/Aids. Sincronicamente, estabeleceram-se ações de prevenção e assistência na rede pública de saúde às DST, centro de testagem, sistema de vigilância epidemiológica, e capacitação de trabalhadoras do sexo. RESULTADOS: Observou-se o fortalecimento das trabalhadoras do sexo como multiplicadoras e sua legitimação como cidadãs e agentes de saúde em projetos com travestis, homossexuais e escolares. Houve incremento da venda de preservativos na cidade, da utilização de preservativos entre trabalhadoras do sexo, redução das DST bacterianas e estabilização da ocorrência de infecção pelo HIV/Aids e sífilis congênita. A sustentabilidade do programa de intervenção estudado, organizado no âmbito do Sistema Único de Saude, foi estimulada pela pactuação política garantindo sede e orçamento regulamentado em lei municipal, e pelo debate permanente dos resultados do processo e programa. CONCLUSÕES: O estudo fortaleceu a noção de que o controle efetivo das DST/Aids depende de uma abordagem sinérgica que combine intervenções no plano individual (biológica-comportamental), sociocultural e programático.


OBJECTIVE: To describe a case study of community-based intervention, developed in a constructionist-emancipatory framework to control STD/AIDS. METHODS: Descriptive study developed in the town of Manacapuru, in the state of Amazonas, from 1997 to 2004, focusing on procedures designed in collaboration with government agents, health professionals and the community. Data on the dynamics of prostitution and condom sales in this town, preventive practices and STD/AIDS care and process assessment were collected. Actions targeting STD prevention and care in the public healthcare system, a testing center, an epidemiological surveillance system and sex workers' qualification were established concomitantly. RESULTS: It was observed the strengthening of sex workers as peer educators and their legitimization as citizens and health agents in projects involving transvestites, homosexuals and students. There was an increase in condom sales in town, as well as in condom use among sex workers; reduction in bacterial STD; and stabilization of the incidence of HIV/AIDS infections and congenital syphilis. The sustainability of the intervention program studied, organized within the sphere of action of the Sistema Único de Saúde (National Health System), was promoted by a political pact, which guaranteed headquarters and municipal law-regulated budget, as well as by the constant debate over the process and program results. CONCLUSIONS: The study strengthened the notion that effective control of STD/AIDS depends on a synergic approach that combines interventions on individual (biological-behavioral), sociocultural and programmatic levels.
