“…This procedure avoids classifi cation of false negatives. 1 Oliveira et al 13 found that the prevalence of the booster effect was 8.4% among the professionals of a university hospital in the city of Campo Grande, Centeral-Western Brazil. In a study among medical students at a university in Rio de Janeiro, Silva et al 17 found a positive booster effect in 1.3%.…”

OBJETIVO: Estimar o risco de infecção tuberculosa em agentes comunitários de saúde envolvidos no controle da doença. MÉTODOS: Foi seguida uma coorte prospectiva, de abril de 2007 a maio de 2008, no município de Cachoeiro de Itapemirim, ES. A coorte foi composta por 61 agentes comunitários, divididos em não-expostos (n=37) e expostos (que acompanharam pacientes com tuberculose, n=24). Durante os 12 meses de seguimento, foi realizado teste tuberculínico, utilizando a tuberculina PPD RT23. Foi calculado o risco relativo e intervalo com 95% de confiança e foi avaliada a correlação entre a viragem tuberculínica e a história ocupacional dos agentes por meio do coeficiente de correlação de Pearson. RESULTADOS: A incidência da viragem foi de 41,7% no grupo dos expostos e 13,5% no grupo dos não expostos. O risco anual de infecção foi de 52,8% no grupo dos expostos e de 14,4% no grupo dos não expostos (p= 0,013). Observou-se associação entre viragem tuberculínica e exposição a paciente com tuberculose (RR= 3,08; IC 95%: 1,201;7,914). CONCLUSÕES: Os agentes que acompanharam pacientes com tuberculose em suas rotinas de serviço apresentaram risco de infecção maior que aqueles que não acompanharam pacientes com essa doença. A implementação de medidas administrativas de biossegurança de rotina, entre as quais a prova tuberculínica, devem ser priorizadas, considerando o alto risco de infecção tuberculosa entre os agentes comunitários de saúde.

“…In Europe and North America, although the prevalence of tuberculosis is lower, the reemergence of this disease has been well described, due to HIV/AIDS pandemics afflicting especially immigrants from Latin American countries and vulnerable populations (refugees, healthcare professionals, inmates and drugs addicts), who are more exposed to tuberculosis infection and disease (4,(21)(22)(23)(24)(25). Brazilian studies indicate a 20 to 50% prevalence of tuberculosis infection in susceptible persons such as healthcare professionals (25).…”

A cross-sectional study on HIV/AIDS was carried out in 108 outpatients from the university hospital of the Federal University of Mato Grosso do Sul, Campo Grande, Brazil, from July to December 2008, to investigate latent tuberculosis infection using the tuberculin skin test (TST). The prevalence of positive results was 13.9%. The CD4+ T cell count (p = 0.091) and the diagnosis time (p = 0.010) were statistically significant when compared with TST positivity. In the cohort of HIV/AIDS patients who had latent tuberculosis infection, the median diagnosis time was eight years. Undetectable viral load presented significant association (p = 0.046) with tuberculosis infection. The fact that numerous individuals with HIV/AIDS infection presented a negative reaction to the tuberculin skin test is probably related to alterations in the cellular immune response induced by HIV infection. The tuberculin test is a useful tool for the detection of latent tuberculosis infection and should be performed in all HIV/AIDS individuals at the time of the diagnosis and on a yearly basis, if negative. Both the early identification of the tuberculosis infection by the tuberculin skin test at the moment of immunological restoration and chemoprophylaxis in infected individuals are mechanisms to control HIV/AIDS and tuberculosis coinfection

“…(1,8) The preventive approach prioritizes individuals who are immunocompromised or are receiving immunosuppressive therapy, children younger than two years of age, and the elderly, as well as health care workers and medical students, who are at a higher risk of becoming infected because of occupational exposure. (9)(10)(11)(12)(13) Latent tuberculosis treatment with isoniazid plays a fundamental role in tuberculosis control and can prevent active tuberculosis in 60-90% of the cases. (13,14) Operational difficulties in identifying latent tuberculosis constitute major obstacles to the implementation of preventive therapy with isoniazid.…”

Objective: To investigate operational aspects of tuberculin skin test (TST) use in tuberculosis control programs and at specialized Brazilian National Sexually Transmitted Diseases/AIDS and Viral Hepatitis Program health care clinics in priority municipalities for tuberculosis control in the state of Mato Grosso do Sul, Brazil. Methods: This was a descriptive, cross-sectional, epidemiological survey. Data on qualifications/training of professionals administering TSTs, timing of the TST, procedures in cases of loss to follow-up (reading), material availability, and material storage were collected through interviews and technical visits. For the 2008-2009 period, we determined the numbers of screenings in vulnerable populations, of TSTs performed, and of patients treated for latent tuberculosis. Results: We interviewed 12 program managers in six municipalities. Some programs/clinics did not perform TSTs. Nursing teams administered the TSTs, results were read by non-specialists, and specialization/refresher courses were scarce. The PPD RT23 was stored in 5-mL flasks under appropriate conditions. Insulin syringes were commonly used. Testing was available during business hours, three times a week. In cases of loss to follow-up, telephone calls or home visits were made. Of the 2,305 TSTs evaluated, 1,053 (46%) were performed in indigenous populations; 831 (36%) were screenings in prisons, performed for training; and only 421 (18%) involved contacts of tuberculosis patients or vulnerable populations. Four vulnerable patients and 126 indigenous subjects were treated for latent tuberculosis. Conclusions: These priority municipalities showed operational difficulties regarding human resources, materials, and data records. ResumoObjetivo: Investigar a operacionalização da utilização do teste tuberculínico (TT) em programas de controle de tuberculose e em serviços de assistência especializada do Programa Nacional de Doenças Sexualmente Transmissíveis/AIDS e Hepatites Virais em municípios prioritários para o controle da tuberculose no estado de Mato Grosso do Sul. Métodos: Estudo epidemiológico descritivo, transversal, do tipo inquérito. A formação profissional dos responsáveis pela realização do TT, existência de treinamentos, período de realização dos TTs, conduta em caso de perda de leitura, insumos disponíveis e sua conservação foram levantados por meio de entrevistas e visitas técnicas. O número de inquéritos em populações vulneráveis, número de TTs realizados e número de pacientes em tratamento de tuberculose latente entre 2008 e 2009 foram também levantados. Resultados: Foram entrevistados 12 gestores de seis municípios. Alguns programas/serviços não realizavam o TT. A equipe de enfermagem realizava os TTs, não havia leitores especialistas, e treinamentos eram raros. A conservação dos frascos de PPD RT23 (5 mL) era adequada. Frequentemente utilizava-se a seringa de insulina. A realização de TT ocorria no horário comercial, três vezes na semana. Em caso de perda de leitura em alguns locais, realizava-se contato...
