[Intravenous pulse methylprednisolone therapy for severe alopecia areata: an open study of 66 patients].
BACKGROUND
Treatment of alopecia areata is a difficult challenge. Some European publications have shown encouraging results with high dose pulse corticosteroid therapy in extensive plurifocal alopecia areata. We undertook a prospective open study between January 2000 and December 2001 using repeated pulse each month, with the aim of identifying the effects of this repetition and underlining the best indications.


METHODS
Sixty-six patients aged 9 to 60 years old presenting an extensive alopecia areata exceeding 30% of the scalp surface (n=47), alopecia totalis (n=8), alopecia universalis (n=8), ophiasic alopecia (n=3), for less than 12 months entered this study. The administered treatment was methylprednisolone 500 mg/d during 3 days or 5 mg/kg twice per day during 3 days in children. These pulses were repeated after 4 and 8 weeks, then a second series was carried out or not according to cases. The main evaluation criterion was the percentage of new terminal hair appearing on the bald areas, appreciated by clinical and photographic evaluation at 3 and 6 months.


RESULTS
Ophiasic alopecia areata did not respond to treatment. A quarter of patients presenting universal alopecia had a good response (higher than 80 p. 100) followed by a relapse in half the cases. Half of the patients presenting alopecia totalis had a good response, which was maintained three times out of four. Multifocal alopecia areata seems the best indication since the patients under study presented a good response in 63.8 p. 100 of cases (78 p. 100 when it was a first episode and 90.5 p. 100 if the treatment had been started in less than 3 months before). The repetition of the pulses did not appear to increase the number of responders.


CONCLUSIONS
This study provides the best indication of pulse methylprednisolone therapy: first recent episode of extensive plurifocal alopecia areata. These results are less convincing in long term history or other forms of alopecia areata.
