Summary

Pathology - Generalized myasthenia gravis (MG) is cause of muscle weakness that can have a significant impact on daily life activity but can also be, when respiratory or bulbar muscles are involved, life-threatening.

Rationale - Additionally to thymectomy, which indication of is still debated in absence of thymoma, the long-term treatment of generalized myasthenia gravis includes usually prednisone and azathioprine. However, the most used scheme for prescribing and tapering corticosteroid in MG resulted in a very important cumulative dose of prednisone. Indeed, at twelve month, more than 50 percent of patients are still daily treated with at least 18 mg of prednisone and the proportion of patients who are in remission and no longer taking prednisone is very low (Palace and NEWSOM Davis, Neurology 1998). Prolonged corticosteroid therapy is accompanied with various and major side effects, hypertension, osteoporosis, weight gain, glaucoma. Therefore, tapering, eventually discontinuing, prednisone earlier is a relevant therapeutic goal.

For this reason, the investigators will compare to the standard one, a strategy consisting of a rapid decrease in corticosteroid.

Objective - To assess whether, in patients with generalized MG requiring a long-term treatment with corticosteroids and azathioprine, that the strategy of rapid tapering allows discontinuing more rapidly the prednisone for equivalent efficacy than the classical strategy.

Conditions

Interventions

DRUG

Prednisone - Azathioprine

Rapid strategy consists of decreasing the prednisone dose if at each monthly consultation the patient fulfils the criteria for improvement or minimal manifestation state, in order to discontinue it before twelve months. The starting dose is 0.75 mg/kg/day. Classical strategy consists of decreasing the prednisone dose if at each monthly consultation the patient fulfils the criteria for minimal manifestation state, in order to discontinue it before twelve months. The starting dose is 1.5 mg/kg/2days.
