title: [Experience in the treatment of acute fulminating myasthenia gravis].
abstract: During past 15 years, 188 myasthenia gravis (MG) patients underwent thymomectomy or thymectomy with extended resection of the adipose tissue around the thymus in our institution. Four of 188 patients (2%) had to be given respiratory support within 2 months after the onset of MG. We defined this MG as the acute fulminating type. There were 2 male and 2 female patients, ranging in age from 22 to 44 years (average, 32.5 years). Three of these patients had thymoma. One of these patients was post-thymomectomy myasthenia gravis and another patient was d-penicillamine induced myasthenia gravis. Two patients admitted on respirator for respiratory crisis. All patients underwent operation within 2 weeks after admission. The duration of respiratory support ranged from 10 to 120 days (mean 44) after operation. The period of the hospital stay ranged from 8 months to 2 years 1 month (mean 1 year 5 months). During acute stage after operation, the patients needed ACTH, steroid, immunosuppressants (azathioprine, Bredinin) and plasma pheresis depending on their severity of myasthenic symptoms. In 2 patients dose of steroid could be reduced without deterioration of the symptoms. They are doing well with small dose of steroid. In one patient plasma pheresis was performed 6 years after thymectomy. Various symptoms due to myasthenia gravis and rheumatoid arthritis has recurred 10 years after thymectomy. The titer of acetylcholine receptor antibody of this patient has been continuing in high level.
