description A study on the frequency and risk factors related to visceral larva migrans (VLM)in 1,131 users of public and private laboratories in Goiania, Brazil, was performed. Antibodies anti-Toxocara canis were analyzed from sera by an immunoenzimaticassay (ELISA) employing as antigen, excretion and secretion products of thirdstage larvae of T. canis. In order to decrease the possibility of crossed reactionswith species of Ascaris genera, sera were treated previously with an extract ofAscaris suum. Samples were considered positive when optical density was above0.3. Qui-square tests were used for evaluation of differences of proportions.The frequency found was 18.9% (CI 95% 16.7-21.3). Besides serum collection,individuals that participated in the study, signed a consent form and were interviewedfor evaluation of the possible risk factors related with the transmission of viscerallarva migrans, such as: presence of dogs in the house and surroundings, historyof living in rural areas, drinking water resources, geophagia, use of river water,ingestion of vegetables without previous treatment, habit of washing hands beforemeals, manipulation of sand or earth. For evaluation of risk factors, odds ratio werecalculated, with the respective confidence intervals of 95%. The presence of dogsin houses and surroundings, history of geophagia and use of non filtered water wererisk factors statistically significant for transmission of VLM, after adjustment forpossible confounding variables. Even if the percentage of 18.9% of serum positivitycannot be extrapolated for the urban population of Goiania, results obtained suggestan elevated frequency of the infection by T. canis in this region.

Para apesquisa de anticorpos anti-Toxocara canis, as amostras de soro foram analisadas pelo ensaioimunoenzimático (ELISA) utilizando-se como antígeno produtos de excreção e secreção de larvas deterceiro estádio de T. canis. Para reduzir a possibilidade de reações cruzadas com espécies do gêneroAscaris, os soros foram previamente tratados com extrato de Ascaris suum. Foram consideradaspositivas as amostras que apresentaram resultados de densidade ótica acima de 0,3. Empregou-seo teste Qui-Quadrado para avaliar diferenças de proporção. A frequência encontrada foi de 18,9%(IC 95% 16,7-21,3). Além da coleta de soro, as pessoas que concordaram em participar do estudoassinaram um termo de consentimento livre e esclarecido e concederam entrevistas para avaliaçãodos prováveis fatores de risco relacionados à transmissão da larva migrans visceral, tais como:presença de cães no domicílio e peridomicílio, história de moradia em zona rural, disponibilidadede água encanada, geofagia, uso de água de rio e cisterna, ingestão de legumes e verduras semhigienização prévia, hábito de lavar as mãos antes das refeições, manipulação de terra e areia.Para avaliação dos fatores de risco, foram calculadas estimativas de risco (Odds Ratio - OR) comrespectivos intervalos de 95% de confiança. Presença de cães no domicílio/peridomicílio, história degeofagia e consumo de água sem filtrar constituíram fatores de risco estatisticamente significativosna transmissão de LMV, após ajuste para possíveis variáveis de confusão. Embora o percentual de18,9% de soropositividade não possa ser extrapolado para a população do aglomerado urbano deGoiânia, os resultados sugerem ser elevada a frequência da infecção por T. canis nesta região.Universidade Federal de Goiás2009-10-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/iptsp/article/view/783810.5216/rpt.v38i3.7838Revista de Patologia Tropical / Journal of Tropical Pathology; Vol. 38 No. 3 (2009); 197-206Revista de Patologia Tropical / Journal of Tropical Pathology; v. 38 n. 3 (2009); 197-2061980-81780301-0406reponame:Revista de patologia tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/iptsp/article/view/7838/5640info:eu-repo/semantics/openAccessdos Santos, Gilcilene MariaSilva, Simonne Almeida eBarbosa, Alverne BarbosaCampos, Dulcinéa Maria Barbosa2014-09-11T19:04:26Zoai:ojs.revistas.ufg.br:article/7838Revistahttps://revistas.ufg.br/iptspPUBhttps://revistas.ufg.br/iptsp/oairpt.iptsp@ufg.br1980-81780301-0406opendoar:2014-09-11T19:04:26Revista de patologia tropical (Online) - Universidade Federal de Goiás (UFG)false
