RESUMO
OBJECTIVE To analyze the prevalence of IgG antibodies to Toxoplasma gondii in patients infected with HIV/AIDS and the association of demographic and social variables. METHODS Descriptive cross-sectional study that included the analysis of sociodemographic data and laboratory findings of 200 patients infected with HIV/AIDS treated in a laboratory unit in Maputo, Mozambique, in 2010. Individual data for all participants were collected with a self-administered questionnaire. Plasma samples were tested for IgG testing of anti- T. gondii using hemagglutination for the analysis of antibodies. RESULTS The seroprevalence of IgG anti- T. gondii was 46.0% (95%CI 39.2;52.9), 39.3% (95%CI 29.5;50.0) in men and 50.9% (95%CI 41.9;59.8) in women, with no difference between sex (OR 1.30; 95%CI 0.95;1.77; p = 0.12). Ages ranged from 10 to 60 years, with a higher prevalence of infection in older age groups, but with no significant difference between them. Regularly consuming cattle meat (OR 1.74; 95%CI 1.04;2.89, p = 0.05), breeding cats/dogs (OR 6.18; 95%CI 3.60;10.62, p < 0.000) and having regular contact with soil (OR 3.38; 95%CI 2.19;5.21; p < 0.000) were significantly associated with risk of latent infection. CONCLUSIONS Toxoplasmosis is an infection with high prevalence in Mozambique. Cultural and behavioral aspects increase the risk. Toxoplasmosis can be responsible in our environment by the great burden of morbidity and mortality associated with meningoencephalic injuries in patients with HIV/AIDS. .
OBJETIVO Evaluar la prevalencia de anticuerpos IgG anti- Toxoplasma gondii en personas infectadas por VIH/SIDA y la asociación de variables demográficas y sociales. MÉTODOS Estudio transversal que incluyó el análisis de datos sociodemográficos y de laboratorio de 200 personas infectadas por VIH/SIDA, atendidas en unidad de laboratorio en 2010 en la Provincia de Maputo, Mozambique. Los datos fueron colectados por medio de cuestionario auto llenado por todos los participantes. Para el análisis de anticuerpos, las muestras de plasma colectadas fueron confirmadas para evaluación anti- T. gondii por hemaglutinación. RESULTADOS La seroprevalencia de IgG anti- T. gondii fue de 46% (IC95% 39,2;52,9), 39,3% (IC95% 29,5;50,0) en hombres y de 50,9% (41,9-59,8%) en mujeres, sin diferencia entre sexo (OR 1.30; IC95% 0.95;1.77; p = 0.12). La edad varió de 10 a 60 años, con mayor prevalencia de infección en grupos etarios más ancianos, pero sin haber diferencia significativa entre ellos. Consumir carne de ganado bovino regularmente (OR 1,74; IC95% 1,04;2,89, p = 0,05), poseer cria de gatos/perros (OR 6,18; IC95% 3,60;10,62, p < 0,000) y tener contacto regular con la tierra (OR 3,38; IC95% 2,19;5,21, p < 0,000) estuvieron significativamente asociados al riesgo de infección latente. CONCLUSIONES La infección por toxoplasmosis presenta alta prevalencia en la población de Mozambique, cuyo riesgo se amplía por los aspectos culturales y de comportamiento. La toxoplasmosis puede ser responsable por la gran carga de morbi-mortalidad asociada a lesiones meningoencefálicas en personas con VIH/SIDA en el país. .
OBJETIVO Avaliar a prevalência de anticorpos IgG anti- Toxoplasma gondii em pessoas infectadas pelo HIV/Aids e a associação de variáveis demográficas e sociais. MÉTODOS Estudo transversal que incluiu a análise de dados sociodemográficos e laboratoriais de 200 pessoas infectadas por HIV/Aids, atendidas em unidade laboratorial em 2010 na Província de Maputo, Moçambique. Os dados foram coletados por meio de questionário autopreenchido por todos os participantes. Para a análise de anticorpos, amostras de plasma coletadas foram confirmadas para testagem de IgG anti- T. gondii por hemaglutinação. RESULTADOS A soroprevalência de IgG anti- T. gondii foi de 46,0% (IC95% 39,2;52,9), 39,3% (IC95% 29,5;50,0) em homens e de 50,9% (IC95% 41,9;59,8) em mulheres, sem diferença entre sexo (OR 1.30; IC95% 0.95;1.77; p = 0.12). A idade variou de 10 a 60 anos, com maior prevalência de infecção em grupos etários mais idosos, mas sem haver diferença significativa entre eles. Ter consumo regular de carne de gado bovino (OR 1,74; IC95% 1,04;2,89, p = 0,05), possuir criação de gatos/cães (OR 6,18; IC95% 3,60;10,62, p < 0,000) e ter contato regular com a terra (OR 3,38; IC95% 2,19;5,21, p < 0,000) estiveram significativamente associados ao risco de infecção latente. CONCLUSÕES A infecção por toxoplasmose apresenta alta prevalência na população de Moçambique, cujo risco amplia-se pelos aspectos culturais e comportamentais. A toxoplasmose pode ser responsável pela grande carga de morbimortalidade associada a lesões meningoencefálicas em pessoas com HIV/Aids no país. .
