A case of myasthenia gravis in which the interval to repeated exacerbation was prolonged by L-carnitine
We report the case of a 62-year-old woman diagnosed with myasthenia gravis. She felt dyspnea and weakness of bilateral upper limbs, followed by left blepharoptosis. Pyridostigmine markedly improved her symptoms. But later, blepharoptosis and head drop worsened and predonisolone was ineffective. Yet, after intravenous immunoglobulin therapy her symptoms markedly improved. However, her head drop worsened at intervals of 25.79 days on average. She was administered L-carnitine, and the interval until exacerbation became longer (40.67 days on average). This case is interesting because L-carnitine therapy has never been reported as therapy for myasthenia gravis. doi：10.11482/KMJ-E43（1）1 (Accepted on December 24, 2016)
