DIAS-TOSTA, Elza  and  MORATO-FERNANDES, Rubens Nelson. Myasthenia gravis: thymectomy, corticosteroid and plasmapheresis therapy. Arq. Neuro-Psiquiatr. [online]. 1989, vol.47, n.1, pp.39-50. ISSN 0004-282X.

This paper reviews a 12 year experience with myasthenia gravis management (surgical and drug therapy). A total of 27 patients were submitted to thymectomy, and 12 out of 13 showed fairly good results with this only form of therapy (15.3% with complete remission, 46.15% with marked improvement and 30.7% with moderate improvement). The other 14 need either a combination of surgery and plasmapheresis or corticosteroids with the cummulative results of: 14.8% of remission (4 out of 27), 74% of improvement (20 out of 27), 7.4% of worsening (2 out of 27) and 3.7% without change (1 out of 27). Two other patients not submitted to surgery showed either a stable state ot their symptoms or a mildly worsening. Another eight patients not submitted to surgery could not be hollowed up. The authors also conclude by the validity of the use of plasmapheresis in myasthenic crises leading to a transient relief of the symptoms and suggest the use of corticosteroids as a second choice, due to their undesirable side effects and difficulty in their reduction and elimination without worsening the symptoms. Other immunosuppressive drugs could be used in cases in which those above cited therapies showed unsuitable results.
