Cobertura vacinal dos profissionais de um curso de especialização em Saúde da Família do Piauí Protección vacunal de los profesionales de un curso de especialización en Salud de la Familia de Piauí Vacinal covering of the professionals of the spcecialization course in Family Health of Piaui

O presente estudo tem como objetivo avaliar a cobertura vacinal dos alunos de um Curso de Especialização em Saúde da Família do Piauí. A população do estudo foi constituída por todos os 43 alunos da turma: 19 enfermeiros, 13 médicos e 11 cirurgiões-dentistas. Os dados foram coletados em 2004, utilizando-se questionários auto-aplicáveis. Encontrou-se uma cobertura vacinal de 81,3% para hepatite B, 76% para a vacina antiamarílica e 65,1% para dT. Além disso, 25 alunos (58,1%) relataram desconhecimento acerca das vacinas preconizadas pelo Programa Nacional de Imunização (PNI). Os resultados mostraram que esses profissionais de saúde não estão adequadamente vacinados, reforçando a necessidade da implantação de uma política sistemática de imunização para eles, tendo como base as normas preconizadas pelo PNI.<br>El presente estudio tiene como objetivo evaluar la protección vacunal de los estudiantes de un Curso de Especialización en salud de la Familia de Piauí-Brasil.

Comparison of Interferon-γ Release Assay to Two Cut-Off Points of Tuberculin Skin Test to Detect Latent Mycobacterium tuberculosis Infection in Primary Health Care Workers

BackgroundAn interferon-γ release assay, QuantiFERON-TB (QFT) test, has been introduced an alternative test for the diagnosis of latent Mycobacterium tuberculosis infection (LTBI). Here, we compared the performance of QFT with tuberculin skin test (TST) measured at two different cut-off points among primary health care work (HCW) in Brazil.MethodsA cross-sectional study was carried out among HCWs in four Brazilian cities with a known history of high incidence of TB. Results of the QFT were compared to TST results based on both ≥5 mm and ≥10 mm as cut-off points.ResultsWe enrolled 632 HCWs. When the cut-off value of ≥10 mm was used, agreement between QFT and TST was 69% (k = 0.31), and when the cut-off of ≥5 mm was chosen, the agreement was 57% (k = 0.22). We investigated possible factors of discordance of TST vs QFT. Compared to the TST-/QFT- group, risk factors for discordance in the TST+/QFT- group with TST cut-off of ≥5 mm included age between 41-45 years [OR = 2.70; CI 95%: 1.32-5.51] and 46-64 years [OR = 2.04; CI 95%: 1.05-3.93], BCG scar [OR = 2.72; CI 95%: 1.40-5.25], and having worked only in primary health care [OR = 2.30; CI 95%: 1.09-4.86]. On the other hand, for the cut-off of ≥10 mm, BCG scar [OR = 2.26; CI 95%: 1.03-4.91], being a household contact of a TB patient [OR = 1.72; CI 95%: 1.01-2.92] and having had a previous TST [OR = 1.66; CI 95%: 1.05-2.62], were significantly associated with the TST+/QFT- group. No statistically significant associations were found among the TST-/QFT+ discordant group with either TST cut-off value.ConclusionsAlthough we identified BCG vaccination to contribute to the discordance at both TST cut-off measures, the current Brazilian recommendation for the initiation of LTBI treatment, based on information gathered from medical history, TST, chest radiograph and physical examination, should not be changed
