Zusammenfassung
Die Myasthenia gravis ist eine erworbene Autoimmunerkrankung, die durch belastungsinduzierte vorzeitige Ermüdbarkeit der Muskulatur gekennzeichnet ist. Bei 85 % der Patienten sind Antikörper gegen den Acetylcholinrezeptor der neuromuskulären Synapse nachweisbar. Daneben finden sich Antikörper gegen den muskelspezifischen Tyrosinkinaserezeptor und das Low-density lipoprotein receptor-related protein 4 (LRP4). Bei etwa 20 % der Erkrankten wird ein Thymom nachgewiesen (häufig mit Titin-Antikörpern). Die Therapie umfasst eine Immunsuppression ergänzt durch Acetylcholinesterasehemmer. Die Thymektomie wird bei der generalisierten Myasthenie mit AChR-Antikörpern im Frühstadium der Erkrankung empfohlen und ist bei Thymomverdacht immer indiziert.
