“…International studies have found a prevalence of 37.7% in the elderly who visited a medical center in Santiago, Chile, 8 and 26.5% among elderly patients at a hospital in Costa Rica. 11 However, more recent studies have identified a lower prevalence in the institutionalized elderly: 12.9% in Porto Alegre, Rio Grande do Sul, 9 and 9.5% in Uberlândia, Minas Gerais. 3 These differences in prevalence may occur due to the socioeconomic and environmental differences between the studied populations.…”

“…Previous studies have reported cases in certain areas where the prevalence of intestinal parasitic infections in elderly population ranges from 9.5% to 72.8%. 3,[7][8][9][10][11] To understand the reality and needs of each region, the Family Health Strategy (FHS) team, which is part of the Unified Health System in Brazil, implements health surveillance, promotion, prevention, and disease control activities. 12 The use of epidemiological tools and the collection of survey data by Community Health Workers (CHW) regarding the social and environmental factors that may affect human health enable closer proximity of health services to the population.…”

RESUMOOBJETIVO: A prevalência de enteroparasitoses é pouco relatada em estudos com a população idosa. Sendo assim, esse estudo teve como objetivo identificar a prevalência de enteroparasitoses associadas a fatores sociodemográficos e de saúde em idosos da Estratégia Saúde da Família (ESF). MÉTODOS: Estudo transversal, realizado com uma amostra aleatória de idosos da ESF do município de Porto Alegre. A coleta de dados foi realizada pelos agentes comunitários de saúde, que aplicaram um questionário geral de inquérito epidemiológico. A coleta de sangue e fezes foi realizada pela equipe do projeto, na unidade de saúde onde o idoso estava cadastrado. RESULTADOS: Foram avaliados 581 idosos e a prevalência de enteroparasitoses foi de 10,8%. Os parasitos encontrados foram: Endolimax nana (42,7%), Entamoeba coli (33,8%), Giardia lamblia (8,8%), Ascaris lumbricoides (5,9%), Strongyloides stercoralis (4,4%), Trichuris trichiura (2,9%) e Iodamoeba bütschlii (1,5%). CONCLUSÃO: A prevalência de enteroparasitoses foi baixa quando comparada com outros estudos e com predomínio de parasitos não patogênicos. Esses achados sugerem a possibilidade de transmissão interpessoal, contaminação ambiental ou mesmo a ocorrência de ingestão de alimentos ou água contaminados. Estes resultados ressaltam a importância da implementação de medidas relacionadas ao saneamento básico e programas contínuos de educação sanitária na comunidade estudada. PALAVRAS-CHAVE: enteropatias parasitárias; idoso; saúde pública. ABSTRACT OBJECTIVE:There are few studies on intestinal parasitic infections in elderly populations. Therefore, this study aimed to determine the prevalence of intestinal parasites and identify the association between this prevalence and the sociodemographic, environmental, and health factors of the elderly attended by the Family Health Strategy (FHS). METHOD: This cross-sectional study involved the analysis of data collected from a random sample of elderly individuals. Community health workers drafted a general questionnaire to collect epidemiological data. The project team also collected blood and stool samples at the healthcare unit where each individual was enrolled. RESULTS: Among 581 elderly people, the prevalence of intestinal parasites was 10.8%. The parasites found were as follows: Endolimax nana (42.7%), Entamoeba coli (33.8%), Giardia lamblia (8.8%), Ascaris lumbricoides (5.9%), Strongyloides stercoralis (4.4%), Trichuris trichiura (2.9%), and Iodamoeba bütschlii (1.5%). CONCLUSION: The prevalence of intestinal parasites in elderly persons was lower than that reported in other studies, and the parasites identified were predominantly non-pathogenic. The findings suggest the possibility that interpersonal transmission, environmental contamination, or the ingestion of contaminated food or water is occurring in this population. These findings also highlight the importance of the ongoing implementation of sanitation and hygiene education programs in this community.

The present study evaluates the prevalence of enteroparasitosis in the urban slums of Belo Horizonte, Brazil and the risk of transmitting enteroparasites to the family members of infected individuals. Stool samples were collected and examined at clinical laboratories near each slum. Individuals were identified and classified as positive for parasitosis (IP z ), and individuals with negative stool tests were classified as negative for parasitosis (IP 2 ) and enrolled as control patients. We collected samples from 594 patients, of which 20.2% and 79.8% were classified as IP z and IP 2 , respectively. In addition, 744 family members (FIPs) effectively participated in the study by providing fecal samples. In total, 1338 participants were evaluated. Of these, 34.6% were tested positive for parasitosis. Blastocystis was the most prevalent parasite, infecting 22.4% of individuals. Among FIPs, the overall prevalence was 46.1%. Of these, 50.6% and 44.7% were classified as FIPs z and FIPs 2 , respectively. These results showed that IP z did not impact the prevalence of infection within the studied communities, not constituting index cases of specific risk behaviors, suggesting that, in fact, these communities are exposed to similar oral-fecal routes of contamination.

“…Among the pathogenic helminths investigated, the one most often diagnosed is Strongyloides stercoralis (S. stercoralis), a nematode parasite that causes strongyloidiasis, a disease characterized by skin and digestive symptoms, in humans [1][2][3][4][5]. Parasitological surveys using more sensitive and rigorous techniques are needed to provide more reliable results and serve as the basis for future interventions involving sanitary and educational measures to improve health maintenance [2]. In this sense, research carried out for the refinement of techniques applied to the epidemiological survey to parasitic diseases, such as the strongyloidiasis, is necessary.…”

The present study is aimed at evaluating serological method using scFv anti-Strongyloides sp. and reporting the frequencies of the results with conventional parasitological technique (faeces) in elderly individuals. Among 112 elderly individuals (≥60 years of age), 14.28% were positive for at least one enteroparasite, with one individual positive for S. stercoralis. Sera were evaluated for the presence of anti-Strongyloides sp. antibodies using total or detergent fraction extracts of Strongyloides venezuelensis, which presented positivity rates of 19.64% and 10.71%, respectively. An anti-HSP60 single-chain variable fragment from Strongyloides sp. was used to detect parasite antigens, with 5.36% (6 individuals) of ELISA-positive individuals returning a positive result. While the serological test indicates previous or recent infection and may be limited by antigen purification, the anti-HSP60 method reflects the presence of Strongyloides sp. immune complexes and exhibits greater sensitivity and specificity. Our results demonstrate the variable occurrence of enteroparasites in elderly individuals residing in long-term nursing homes and validate a novel epidemiological tool to describe infection cases by Strongyloides sp.
