[Systemic manifestations of myasthenia gravis and its putative pathogenesis].

Journal Article (English Abstract;Journal Article)

We studied the systemic manifestations of myasthenia gravis and its putative pathogenesis. 644 clinically, pharmacologically and electrophysiologically diagnosed patients with myasthenia gravis (MG) were studied. 33 patients had Graves disease, 5 periodic paralysis, 4 Hashimoto disease, and 4 epilepsy, polymyositis, rheumatoid arthritis and Guillain-Barre syndrome each. 45 patients had positive anti-skeletal-muscle antibodies, 9 positive anti-thyroid antibody, and 3 positive SSA and SSB. 11 MG patients with positive pyramidal signs (MG+PS) had no evidence of multiple sclerosis (MS) or other neurologic diseases. Compared with 12 MG patients without pyramidal signs (MG-PS) and 23 normal controls (NCs), they had not only high levels of IgGcsf and IgG syn, but also increased ratio of AChRAbcsf/AChRAbs (P < 0.05). Four MG patients had epilepsy. Four MG patients had severe memory disorders. Three MG patients had diseases of the peripheral nerves without diabetes mellitus and toxin. SGPT was significantly increased in 22 MG patients than in 9 normal controls (P < 0.05). These systemic manifestations were improved while MG was improved by immunological therapy. MG is a systemic autoimmune disease predominantly involving AChR on the postsynaptic membrane of N-M conjunction.
