She recently became pregnant and stopped her medication, but her neurological exam discloses only mild low visual acuity without fatigue. She was treated with 3g IV methylprednisolone and symptoms resolved completely. We desmislinizantes describe three Brazilian patients with MG that presented different DD and discuss their clinical courses. MG has a bimodal incidence: The occurrence of DD in association to MG doennas been reported before, and are described as monophasic events myelitis, acute disseminated encephalomyelitis and optic neuritis and recurrent diseases multiple sclerosis, recurrent transverse myelitis and NMO 7, Symptoms resolved completely and his visual acuity returned to normal 2 months later.

We report on a series of Brazilian patients that presented distinct DD years after the diagnosis of MG. While we evaluated ambulatory patients, Gotkine et al surveyed patients that were admitted to the hospital, which does not reflect the whole population of patients with MG in a tertiary care center.


Some authors state that this association may not happen by chance, as the incidence of DD in patients with MG is much higher than expected in the general population 6,15and both may be part of multiple autoimmune syndromes or genetic predisposition to autoimmunity 5.

This methodological difference may have left to selection bias of more severe patients, among them those with DD. Most patients respond to steroid therapy prednisone. Desmieliizantes with MG commonly have thyroid disease and can present with nonspecific immune system abnormalities, such as positive auto antibodies and alopecia areata For all other comments, please send your remarks via contact us.

J Allergy Clin Immunol ; Although all our patients achieved a good control of myasthenia symptoms, we could not determine the influence of developing DD on MG control due to the small number of patients in this series.

In this series of patients, only one developed a relapsing-remitting disease with positive low titer ANA and the others presented a monophasic course.

On first evaluation she had an atrophic optic disc on the left side, mild spastic gait and increased muscle stretch reflexes. She underwent thymectomy one year later and evolved asymptomatic on pyridostigmine treatment, thymus pathology disclosed lymphoid hyperplasia.
