Successful treatment of idiopathic orbital inflammation with mycophenolate mofetil.

PURPOSE: To report our experience with the use of mycophenolate mofetil for treatment of idiopathic orbital inflammation (IOI).

DESIGN

Noncomparative interventional case series.

METHODS

We reviewed the records of five patients with IOI who were treated with mycophenolate mofetil. The indications for use included recurrent inflammation after other therapies (four patients) and to avoid corticosteroid-induced blood sugar elevation in poorly controlled diabetes mellitus (one patient). Treated patients were followed for a median of 8.5 months (range, 4-30 months) after mycophenolate mofetil therapy was begun. Main outcome measures were response to treatment, treatment-related side effects, drug dosage, previous and final treatment regimens, and discontinuation of systemic corticosteroids.

RESULTS

Mycophenolate mofetil therapy was discontinued in one patient because of nausea. Each of the remaining four patients experienced complete resolution of orbital inflammation. Of these, only one patient remains on prednisone, but at a significantly reduced dose (1 mg/d).

CONCLUSION

Mycophenolate mofetil therapy resulted in the resolution of inflammation in patients with refractory or corticosteroid-dependent IOI and was used successfully for a first episode of IOI in a patient for whom corticosteroids were contraindicated.
