Enteric-coated mycophenolate sodium in the treatment of refractory pemphigus.
BACKGROUND
One of the major goals of pemphigus therapy is to reduce the patient's cumulative exposure to systemic corticosteroids. To investigate the efficacy of enteric-coated mycophenolate sodium (EC-MPS), 10 patients with active, refractory pemphigus vulgaris (PV) or foliaceous (PF) were treated with EC-MPS (1440 mg daily) and prednisone (75 mg daily) over 18 months.


METHODS
Following EC-MPS/prednisone therapy, disease progression was inhibited between days 30 and 45 in 9/10 patients (8 PV; 1 PF). At 18 months, 8/9 PV patients had clinically quiescent disease; EC-MPS therapy was no longer required in two patients as a result of disease remission. The remaining PV patient showed no response to treatment. The PF patient also had clinically quiescent disease but with high levels of anti-desmoglein-1. ECMPS dose was reduced to 720 mg daily in 4/9 patients by month 6. Average daily prednisone requirement decreased to 25 mg at 6 months and to 15 mg at 18 months. Three adverse events were reported: headache (two cases; one mild and one moderate) and significant increase in blood glucose (one case; moderate).


CONCLUSIONS
Enteric-coated mycophenolate sodium is effective and safe as an adjuvant therapy in patients with refractory pemphigus and may be effective even in patients whose disease is unresponsive to azathioprine.
