Informations about the disease
Eine Reihe von neuromuskuläre Erkrankungen (NMD) betreffen auch den Gastrointestinaltrakt (GIT). Je nach NMD-Typ variiert die Prävalenz einer GIT-Beteiligung zwischen < 5 % (z. B. hereditäre Neuropathien, myofibrilläre Myopathien) und 100 % (z. B. MNGIE, OPMD). Insbesondere bei NMD mit Multisystembeteiligung kann die GIT-Beteiligung das klinische Erscheinungsbild dominieren oder zumindest einen signifikanten Teil des Krankheitsbildes ausmachen. Vertreter von NMD mit Multisystembeteiligung sind u. a. die mitochondrialen Erkrankungen (MID) und die myotonen Dystrophien. Syndromale MID mit GIT-Beteiligung sind u. a. das MNGIE-, das MELAS-, das Leigh- und das Pearson-Syndrom. Unter den Neuropathien findet man eine GIT-Beteiligung am häufigsten bei ALS und GBS. Eine GIT-Beteiligung kann auch ein Merkmal der Myasthenie sein. Die klinischen Manifestationen einer Magen-Darm-Beteiligung sind vielfältig und können den gesamten Magen-Darm-Trakt betreffen, von den Zähnen bis zum Rektum, einschließlich Leber und Bauchspeicheldrüse. Die bekanntesten klinischen Manifestationen einer Magen-Darm-Beteiligung sind Dysphagie, Übelkeit, Erbrechen, Reflux, Motilitätsstörungen der Hohlorgane, Hepatopathie, Diabetes, Durchfall, Verstopfung und Stuhlinkontinenz.
