TIMEROSAL CONTIDO EM VACINAS E TRANSTORNOS DO ESPECTRO AUTISTA: REVISÃO DE LITERATURA
Resumo
O transtorno do espectro autista (TEA), antes considerado um distúrbio raro, passou a ter prevalência maior do que o câncer infantil, o diabetes e a síndrome de Down. Nos últimos anos houve crescimento exponencial do número de pesquisas sobre fatores ambientais associados ao TEA, dentre os quais se destacam os estudos epidemiológicos de associação entre TEA e timerosal contido em vacinas (TCV). O objetivo deste estudo foi analisar o progresso desses estudos e verificar se há consenso entre os pesquisadores. As bases MedLine e Scopus e a Biblioteca Virtual em Saúde (BVS) foram consultadas para identificar artigos publicados entre 2000 e 2017, adotando como termos de busca (em língua inglesa): “thimerosal”; “thiomersal”; “ethilmercury”; “autism spectrum disorder”; e “autism”. Dezesseis artigos foram selecionados por meio da leitura de títulos e textos. Observou-se que não houve consenso entre os pesquisadores dos Estados Unidos da América (EUA) sobre a associação entre timerosal e TEA, entretanto, todos os autores dos demais países concluíram não haver essa associação.
