ABSTRACT Objective: To estimate the prevalence of Sexually Transmitted Infections (STIs) in immigrants and refugees living in the metropolitan region of Goiânia, Goiás. Method: This is a cross-sectional and analytical study. Data collection was carried out from July 2019 to January 2020 and 308 immigrants and refugees were included in the sample. All were underwent face-to-face interviews and were tested for HIV, Syphilis, and Hepatitis B, using rapid tests. Results: The general prevalence for any of the STIs investigated was 8.8% (95%CI 6.0% – 12.3%), being 5.8% (95%CI 3.6% – 8.9%) for Hepatitis B, 2.3% for Syphilis (95%CI 1.00% – 4.4%) and 0.7% for HIV (95%CI 0.1% – 2.1%). Multiple analysis, using logistic regression, showed that the variables male gender (OR = 2.7) and length of time living in Brazil (OR = 2.6) were significantly associated with STIs (p < 0.05). Conclusion: The results of this study suggest that STIs are a health problem in immigrants/refugees, which appear to be enhanced with the length of migration in the country. Public policies that guarantee health care for this population shall be considered.

RESUMEN Objetivo: Estimar la prevalencia de Enfermedades de Transmisión Sexual (ETS) en inmigrantes y refugiados residentes en la región metropolitana de Goiânia, Goiás. Método: Se trata de un estudio transversal y analítico. La recolección de datos se llevó a cabo desde julio de 2019 hasta enero de 2020 y se incluyeron en la muestra 308 inmigrantes y refugiados. Todos fueron entrevistados cara a cara y sometidos a pruebas de VIH, Sífilis y Hepatitis B, mediante pruebas rápidas.. Resultados: La prevalencia general para cualquiera de las ETS investigadas fue de 8,8% (IC95% 6,0% – 12,3%), siendo 5,8% (IC95% 3,6% – 8,9%) para Hepatitis B, 2,3% para Sífilis (IC95% 1,00% – 4,4%) y 0,7% para VIH (IC95% 0,1% – 2,1%). El análisis múltiple, mediante regresión logística, mostró que las variables género masculino (OR = 2,7) y tiempo de residencia en Brasil (OR = 2,6) se asociaron significativamente con las ETS (p < 0,05). Conclusión: Los resultados de este estudio sugieren que las ETS son un problema de salud en inmigrantes/refugiados, que parecen exacerbarse con la duración de la migración en el país. Se deben considerar políticas públicas que garanticen la atención de la salud de esta población.

RESUMO Objetivo: Estimar a prevalência de Infecções Sexualmente Transmissíveis (IST) em imigrantes e refugiados residentes na região metropolitana de Goiânia, Goiás. Método: Trata-se de um estudo transversal e analítico. A coleta de dados foi realizada no período de julho de 2019 a janeiro de 2020 e integraram a amostra 308 imigrantes e refugiados. Todos foram entrevistados face-a-face e testados para HIV, Sífilis e Hepatite B, por meio de testes rápidos. Resultados: A prevalência geral para alguma das IST investigadas foi de 8,8% (IC95% 6,0% – 12,3%), sendo 5,8% (IC95% 3,6% – 8,9%) para Hepatite B, 2,3% para Sífilis (IC95% 1,00% – 4,4%) e 0,7% para HIV (IC95% 0,1% – 2,1%). A análise múltipla, por regressão logística, mostrou que as variáveis sexo masculino (OR = 2,7) e tempo de moradia no Brasil (OR = 2,6) foram associadas significativamente às IST (p < 0,05). Conclusão: Os resultados deste estudo sugerem que as IST são um problema de saúde em imigrantes/refugiados, que parecem ser exacerbadas com o tempo de migração no país. Políticas públicas que garantam a assistência à saúde dessa população devem ser consideradas.

ABSTRACT OBJECTIVE To estimate the prevalence of hepatitis A virus (HAV) and hepatitis E virus (HEV) among immigrants and refugees in Goiás, Central Brazil. METHODS Overall, 355 individuals were interviewed, and blood samples were tested for anti-HAV and anti-HEV IgG. Anti-HEV-positive samples were similarly tested for HEV RNA. RESULTS All participants were from Latin American countries, most of whom, young adult males. The overall anti-HAV IgG prevalence was 87.4% (95%CI: 83.5–90.4), of whom 94.9%, 75.6%, and 60% were from Haiti, Venezuela, and other Latin American countries, respectively (p < 0.001). Age above 19 years and more than 36 months residing in Brazil were associated with a higher prevalence of previous HAV and HEV infection, respectively. Of the children eligible for HAV vaccination according to the National Immunization Program, only eight (44%) had been vaccinated. The overall anti-HEV IgG prevalence was 6.5% (95%CI: 4.4–9.5). All anti-HEV IgG-positive individuals were Haitians, including a child born in Brazil. HEV RNA was detected in two of the anti-HEV IgG-positive samples. CONCLUSION The survey detected a high prevalence of anti-HAV and anti-HEV IgG among immigrants and refugees, and active HEV infection among some Haitian participants. Prevention measures are urgently required to interrupt enteric virus transmission in this emergent and vulnerable population.

Pregas vestibulares (PV) são responsáveis pela proteção das vias aéreas superiores e, nos indivíduos com AIDS, apresenta diminuição das células imunes, o que influencia na estrutura dos folículos linfoides (FL). OBJETIVO: Caracterizar a fibrose e a produção de imunoglobulinas nos FL das PV nos indivíduos com AIDS, com e sem infecções e subnutrição associadas. MATERIAIS E MÉTODOS: Foi realizado um estudo retrospectivo transversal em 71 PV de adultos autopsiados. Para a análise morfológica foi usada a coloração picro-sirius. A imuno-histoquímica foi realizada com os anticorpos: anti-IgA, anti-IgG, anti-IgM. RESULTADOS: Nos pacientes com AIDS, a quantidade de fibrose foi menor quando comparados com aqueles que não possuíam AIDS, o mesmo sendo encontrado nos pacientes com infecções ou subnutrição. As quantidades de IgA e IgG foram maiores nos indivíduos com AIDS, e os valores de IgM foram maiores nos casos com infecção. CONCLUSÃO: Este estudo contribui para o melhor conhecimento da variação dos constituintes dos FL das PV nos indivíduos com AIDS, bem como da influência de modificações arquiteturais, e da associação de outras entidades, como infecções respiratórias e a subnutrição, sobre a função destes FL.

Vestibular folds (VF) protect upper airways, but contain fewer immune cells in AIDS patients, which affects the structure of lymphoid follicles (LF). OBJECTIVE: To characterize fibrosis and immunoglobulin production in vestibular fold lymphoid tissues of AIDS patients with or with no infection and malnutrition. MATERIALS AND METHODS: A retrospective study of 71 adult vestibular fold autopsy specimens. The morphological analysis was done using the picrosirius staining method. Immunohistochemical methods consisted of anti-IgA, anti IgG, and anti IgM antibodies. RESULTS: Fibrosis was less intense in AIDS patients compared to subjects without AIDS; the same applied to patients with infection or malnutrition. IgA and IgG titers were higher in AIDS patients; IgM titers were higher in cases with infection. CONCLUSION: This study helps understand variations in lymphoid follicle components of AIDS patients; it also shows the influence of architectural changes and the effect of associated respiratory infection and malnutrition on lymphoid follicle function.
