Polymyositis Followed by Myasthenia Gravis.

Serum immunogloblin levels in myasthenia gravis, polymyositis, and dermatomyositis.

Analyses of serum immunoglobulin (Ig) levels were performed in patients with myasthenia gravis, polymyositis and dermatomyositis, and in normal subjects. The mean IgG levels were elevated in the disease groups and there was minimal depression of serum IgM levels in nonthymectomized myasthenic patients. There was no consistent pattern with regard to selective immunoglobulin class abnormalities, ...

A case of myasthenia gravis in a 15 years old girl is pre·sented. The disease was present for 5 years before thymectomy was performed. Indications for thymectomy, preoperative pre­paration, anesthetic and surgical management is -discussed. 

Mitogen and muscle extract induced in vitro proliferative responses in myasthenia gravis, dermatomyositis, and polymyositis.

We have compared the lymphocyte in vitro proliferative response induced by muscle extract, phytohaemagglutinin, and pokeweed mitogen in peripheral blood lymphocytes of patients with myasthenia gravis, polymyositis, dermatomyositis, and normal subjects. Similar mean responses to antigen and mitogen were seen in cells of all groups of patients. The proliferative responses induced by muscle did no...
