Treatment of myasthenia gravis with mycophenolate mofetil: a case report

We report a patient with myasthenia gravis (MG) who had marked clinical benefit in response to treatment with mycophenolate mofetil as documented by serial quantitative measures of strength and muscle fatigue. Our patient had experienced either adverse side effects or a suboptimal response to the usual immunosuppressive agents used in MG. Mycophenolate mofetil was used in combination with cyclosporine and prednisone and allowed for significant reductions in dosage of these immunosuppressants. We conclude that mycophenolate mofetil deserves further study as a therapeutic agent in MG. In particular, its role as a steroid-sparing agent and as a drug to be used in combination immunotherapy in more severe or refractory cases of MG should be investigated.
