[Prospective study of treatment of bullous pemphigoid by a class I topical corticosteroid]

The high mortality at 1 year of patients with bullous pemphigoid is considered to be due mainly to systemic corticosteroids. We report 20 cases of bullous pemphigoid treated solely with class I topical corticosteroid.

Twenty patients with bullous pemphigoid grade 1 and grade 2 were treated with clobetasol propionate 0.05 p. 100 cream at the initial dose of 12 mg/m2/day, progressively tapered over months. Severe forms of bullous pemphigoid covering more than 60 p. 100 of total body area were excluded.

35 p. 100 of the patients obtained a remission and 35 p. 100 healed (62.5 p. 100 of the mild forms, 16.7 p. 100 of the moderate forms). The average follow up was 11 months after the end of treatment. Side-effects were mild (cutaneous infections, dermal atrophy). Transitory biological anomalies were observed, mainly related to systemic absorption of clobetasol propionate. Some systemic adverse reactions were noted not necessarily attributed to treatment.

Topical steroid treatment was efficient in patients with mild bullous pemphigoid. Our results were comparable to those reported in the literature except for some cutaneous side effects.
