CURATIVE EFFECT OF DEXAMETHASONE-CYCLOPHOSPHAMIDE PULSE THERAPY FOR THE TREATMENT OF PEMPHIGUS-VULGARIS

In 1982, five patients having pemphigus vulgaris, four men and one woman, ranging in age between 16 and 48 years, were treated with an arbitrary regimen designed by us. The regimen consisted of giving 100 mg dexamethasone in 500 mL of 5% glucose by a slow intravenous infusion on three consecutive days, along with 500 mg cyclophosphamide on one day only. Such dexamethasone-cyclophosphamide pulses (DCP) were meant to be given once a month, but most patients were not regular in this treatment. In between these pulses the patients received only 50 mg cyclophosphamide orally per day. Oral corticosteroids were given only when necessary. After having received a total of 14 to 48 DCPS, further treatment for pemphigus was withdrawn. All the patients are in continuous clinical remission for the last 4 to 9 years and without any treatment for 2 to 7 years. Further studies on more pemphigus patients have yielded similar results suggesting that it may be possible to cure pemphigus.
