Síndrome de Marfan, FBN1, Diagnóstico, Tratamento, TGF-βResumo
O presente estudo consiste numa revisão bibliográfica das bases de dados PubMed e Scielo. Os artigos foram buscados utilizando a expressão Marfan Syndrome. Obteve 239 artigos de livre acesso no PubMed e 06 no Scielo, foram selecionados 37 trabalhos mais relevantes dos últimos cinco anos no tocante aos aspectos genéticos, fisiopatologia, diagnóstico e tratamento, e mais sete de datas anteriores, devido a sua importância histórica. Síndrome de Marfan é uma doença sistêmica, autossômica dominante do tecido conjuntivo causada por mutações nas proteínas da matriz extracelular, especialmente a fibrilina-1. Afeta principalmente os sistemas cardiovascular, esquelético e olhos. As manifestações mais freqüentes são: aneurisma de aorta torácica, luxação do cristalino ocular e crescimento exagerado de ossos longos. Há um novo entendimento sobre o papel da regulação do fator de crescimento tumoral β. Esta revisão destaca fisiopatologia, manifestações clínicas, tratamento padrão, bem como opções terapêuticas inovadoras. Considera importante o acompanhamento multidisciplinar, objetivando o diagnóstico precoce, reduzindo a morbimortalidade dos indivíduos afetados.
