Superpotent topical corticosteroids (CS) have been demonstrated to improve bullous pemphigoid (BP) patients' survival. We assessed whether a mild regimen using lower doses of topical CS and a shorter duration could improve the outcome of BP patients even more. Three-hundred and twelve BP patients were included in a multicenter randomized controlled trial and stratified depending on the extent of BP as moderate (n=134) or extensive (n=178). Patients were randomly assigned to the standard regimen (clobetasol propionate cream, 40 g per day initially, with CS tapering over 12 months) or the mild regimen (10-30 g per day), with CS tapering over 4 months. A noninferior rate of BP control was obtained with the mild regimen 156/159 (98%) as compared with the standard regimen 150/150 (100%; P=0.005). Event-free survival, that is, the combined outcome of deaths and life-threatening adverse events did not differ between the two treatment groups (P=0.77). However, upon adjusting through the Cox model for age and Karnofsky score, a strong beneficial effect of the mild regimen was observed in patients with moderate BP, with an almost twofold decrease in the risk of death or life-threatening adverse events relative to the standard regimen (hazard ratio=0.54; 95% confidence interval, 0.30-0.97; P=0.039). This mild regimen allows a 70% reduction of the cumulative doses of CS and improves BP patients' outcome.
