Soroepidemiologia de Toxoplasma gondii em idosos atendidos pela Estratégia Saúde da Família, Porto Alegre, Rio Grande do Sul, Brasil

Abstract

O objetivo desse estudo foi avaliar a soroprevalência para Toxoplasma gondii e a relacionar com as condições socioeconômicas, higiênicas, sanitárias e de saúde nos idosos da Estratégia Saúde da Família - ESF, do município de Porto Alegre, Rio Grande do Sul, Brasil. A pesquisa realizada foi um estudo transversal, no qual foi aplicado um questionário de inquérito epidemiológico e realizada coleta de sangue. A avaliação de IgG e IgM anti-T. gondii foi realizada pela técnica de ELISA. Foram avaliados 599 idosos com soroprevalência para IgG anti-T. gondii de 88,0% e de 0,8% para IgM. Na análise multivariada, as variáveis que se associaram de forma independente para IgG positivo foram: faixa etária, renda pessoal e uso de óculos; e para IgM positivo: faixa etária, autopercepção de saúde e uso de óculos. Os resultados obtidos chamam a atenção pela alta prevalência de IgG anti-T. gondii nos idosos da ESF de Porto Alegre, gerando uma preocupação no caso de ocorrência de reativação da toxoplasmose e desenvolvimento dos sintomas mais graves dessa infecção.

Prevalence of seropositivity for toxoplasmosis in pregnant women in the Brazilian Federal District from 2014 to 2018

“…This result is in accordance with global data and national, since the World Health Organization (WHO) estimates that more than half of the world population is infected, this prevalence being conditioned to the social and economic determinants that differentiate countries [19,24,25]. According to studies in Brazil, the prevalence indicators for antibodies to toxoplasmosis vary from 54% to 80% [18][19][20][21][22][23][24][25]. The prevalence of toxoplasmosis infection, studied here, decreased over the period studied: from 81.84% in 2014 to 38.65% in 2018.…”

“…The WHO (World Health Organization) estimates that more than half of the world's population is infected, however, most individuals are asymptomatic and do not develop the disease [17]. The prevalence of infection can vary for each country, depending on its social and economic determinants [19,24,25]. In Brazil, the prevalence indicators for antibodies to toxoplasmosis vary widely, from 54% to 80%, with an equal distribution in both sexes, seroprevalence that increases with age and depends on different factors that influence its epidemiology.…”

Spatial and simultaneous representative seroprevalence of anti-Toxoplasma gondii antibodies in owners and their domiciled dogs in a major city of southern Brazil

“…More importantly, previous studies were mostly performed in specific toxoplasmosis risk groups such as pregnant women, children or elderly men, in contrast to the random household approach in the present study [51,52]. …”

“…gondii seroprevalence has been reported [52], while high socio-economic status was negatively associated [64]. Among low income workers, T .…”

Psychometric characteristics of the full and short versions of the IQCODE-BR among low income elderly persons with a low educational level

“…Of these, 7.0% have no income, 54.7% earn less than the minimum wage, 25.0% earn the equivalent of one to two monthly minimum wages, 5.0% earn the equivalent of two to four times the monthly minimum wage and approximately 2.0% earn the equivalent of four to six monthly minimum wages, as described in other studies using the same population group. 17,18 A total of 87 elderly individuals aged 60 to 90 years treated at the Ambulatório de Envelhecimento Cerebral ("Brain Aging Clinic") (AMBEC) in the period from March to December 2013, who were accompanied by an informant they had known for at least ten years, were included in the study. The AMBEC was created specifically at the Neurology Service of the Hospital São Lucas of PUCRS to care for the mental health of elderly individuals registered with PENCE.…”
