O potencial terapêutico da hidroxicloroquina no tratamento de alopecias autoimunes
##plugins.themes.bootstrap3.article.main##
Resumo
Objetivo: Analisar os tipos de alopecias autoimunes que se beneficiam com o uso de hidroxicloroquina. Métodos: Trata-se de uma Revisão Integrativa da Literatura, com buscas nas plataformas National Library of Medicine (PubMed), Scientific Electronic Library Online (SciELO), Literatura Latino Americana e do Caribe em Ciências da Saúde (LILACS), a Biblioteca Virtual em Saúde (BVS) e o Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), em que foram usados Descritores em Ciências da Saúde (DeCS) em inglês: "Hydroxychloroquine" AND "Alopecia". Com a aplicação dos critérios de inclusão e exclusão, foram selecionados 29 artigos que constituíram essa pesquisa. Resultados: Foi observado que a eficácia da hidroxicloroquina (HCQ) varia entre os tipos de alopecias autoimunes, sendo frequentemente combinada a outras terapias, e seu uso exige monitorização. O subtipo mais abordado nos estudos foi a alopecia fibrosante frontal, com destaque na estabilização do quadro, principalmente quando utilizada em combinação com outras terapias. Considerações finais: A HCQ mostrou maior eficácia em alopecias autoimunes cicatriciais, com estabilização inflamatória e perfil de segurança favorável, especialmente em uso prolongado e combinado. Já nas alopecias não cicatriciais, os resultados foram inconsistentes, restringindo seu uso a casos refratários.
