To compare the efficacy of oral prednisolone pulse therapy in comparison to the intravenous methylprednisolone pulse therapy in treatment of severe alopecia areata.

Forty patients with severe alopecia areata were enrolled and divided into 2 groups. Group A was treated with 200 mg oral prednisolone in one dose, every week for 3 months and group B were treated with 500 mg intravenous methylprednisolone on 3 continuous days each month for 6 months. Recovery rate after 1, 3, 6 and 12[th] months after treatment was significantly higher in group B compared to group A. Side effects included: acne [5 in group A and 7 in group B], heartburn [4 in group A and 5 in B], striae [4 in group A and 6 in group B] and were more seen in group B but it was not significant statistically. The recovery and rate was not significantly different between two sexes. In this study, 500 mg intravenous methylprednisolone in 3 continuous days each month for 6 months showed a better recovery rate in severe alopecia areata.
