Long‐term efficacy of mycophenolate mofetil in the control of severe intraocular inflammation

PURPOSE: To assess whether the previously demonstrated short-term efficacy of the immunosuppressant mycophenolate mofetil (MMF; CellCept, Roche) is maintained in the long-term management of refractory uveitis. METHODS: The study was an open-label, non-comparative retrospective series of 14 patients with refractory uveitis and treated with MMF for a mean of >33 months. Mycophenolate mofetil was given at a dosage of 1 g (oral) twice daily. Indications included prednisolone reduction, additive agent with cyclosporin, or replacement therapy (azathioprine or methotrexate). The intraocular inflammatory response, side-effects, and toxicity were monitored. RESULTS: Intraocular inflammation remained under control in 10 patients, unchanged in three and deteriorated in one patient. Transient side-effects included tiredness, headache and dizziness (one patient each, lasting less than 2 weeks from the time of MMF introduction). Mycophenolate mofetil was stopped in one patient because of absence of prolonged clinical improvement. Vision improved in 25% (7 eyes), did not change in 50% (14 eyes), but was reduced in 25% (7 eyes). CONCLUSIONS: Mycophenolate mofetil is safe for long-term usage and is recommended for treatment of refractory panuveitis or posterior uveitis with uncontrolled inflammation despite high prednisolone maintenance dosage (>15 mg/day) or toxicity or lack of efficacy of other immuno-suppressive agents. However, MMF is less effective for refractory uveitis unresponsive to azathioprine.
