9 However, clinicians should be cautious about discontinuing immunotherapy completely, as only about 10% of patients may achieve complete stable remission off immunotherapy. Approximately half of patients can achieve remission or minimal symptoms with low-dose immunotherapy. In the long term, it is preferable to steadily minimize immunosuppression if the patient’s condition remains stable, while watching for relapse or exacerbation. 4,8,9 An exception is in refractory myasthenia gravis, which accounts for approximately 10% of patients with generalized myasthenia gravis and can be associated with relapses and exacerbations late in the course. Patients who endure the first three years with relatively good symptom control tend to have a higher chance of gradual improvement or a steady state and, less often, worsening of the disease. While the early goal should focus on aggressive treatment to improve the patient’s functional status, care must be taken to avoid serious adverse effects from intense immunotherapy. However, the aforementioned studies of the natural course help guide the assessment of risks and benefits of immunosuppressive treatment. More immunotherapies for myasthenia gravis are now available. 4,5 In more recent series, the percentage of generalization from the ocular subtype was less, as low as 20% 6 to 50%. 4 In older studies, approximately two-thirds of cases of ocular myasthenia gravis subsequently progressed into the generalized subtype of these, approximately 80% did so within the first year and 90% within the first three years. In particular, ocular myasthenia gravis reaches its maximal severity within the first three years in most patients. In several such early studies, the mortality and morbidity rates were highest within the first three years of the disease and lower thereafter. 1 As a result, studies of its outcome done before the late 1960s generally reflected its natural course.

Not until the late 1960s was myasthenia gravis recognized as an immune-mediated disorder, and immunotherapies such as corticosteroids, azathioprine and methotrexate started to be used as treatments for it. Myasthenia gravis tends to progress, especially in the first several years, so we recommend treating it aggressively with immunosuppressants at the outset and then gradually easing back. How does the natural course affect the treatment strategy? The following frequently asked questions and answers aim to provide up-to-date, clinically relevant information about myasthenia gravis. Myasthenia gravis is typically categorized as either ocular (in which weakness is limited to the extrinsic ocular muscles and levator palpebrae superioris) or generalized (in which muscles beyond those in the ocular form are involved). A chronic autoimmune neuromuscular disorder causing skeletal muscle weakness, its primary pathophysiology involves dysfunction of the postsynaptic aspect at the neuromuscular junction, mainly a loss of acetylcholine receptor (AChR) function on the muscle membrane. The name “myasthenia gravis” comes from the Greek for muscle weakness and the Latin word for grave or serious. Part 1 is focused on questions pertaining to evaluation and diagnosis of myasthenia gravis.
