Miastenia gravis: a propósito de uma caso clínico
Palavras-chave:
acetilcolina, autoimune, miastenia gravisResumo
A miastenia gravis é uma doença autoimune da
junção neuromuscular na qual se verifica a produção
de anticorpos dirigidos contra os receptores
nicotínicos da acetilcolina, localizados na membrana
pós-sináptica. Esse ataque autoimune traduz-se,
clinicamente, por fraqueza muscular com
predomínio bulbar e fadiga com actividade muscular repetida.
Os autores, a propósito de um caso clínico,
discutem a etiopatogenia, manifestações clínicas,
diagnóstico e opções terapêuticas na miastenia gravis.
