Svensk definition
En autoimmun sjukdom som kännetecknas av svaghet och utmattningstendens i proximala muskler, särskilt i bäckengördeln, benen, bålen och skuldergördeln, medan ögonmusklerna förblir relativt opåverkade. Småcelligt karcinom i lungorna är en vanlig komplikation, men även andra elakartade tillstånd och autoimmuna sjukdomar kan ingå. Muskelsvagheten beror på försämrad signalöverföring vid nerv-muskelkontakten. Bristande presynaptisk kalciumkanalfunktion leder till att för lite acetylkolin frigörs i förhållande till nervretningen.
Engelsk definition
An autoimmune disease characterized by weakness and fatigability of proximal muscles, particularly of the pelvic girdle, lower extremities, trunk, and shoulder girdle. There is relative sparing of extraocular and bulbar muscles. CARCINOMA, SMALL CELL of the lung is a frequently associated condition, although other malignancies and autoimmune diseases may be associated. Muscular weakness results from impaired impulse transmission at the NEUROMUSCULAR JUNCTION. Presynaptic calcium channel dysfunction leads to a reduced amount of acetylcholine being released in response to stimulation of the nerve.
