摘要
The calcipotriene/betamethasone dipropionate two-compound scalp formulation has been shown to be safe and effective in the treatment of scalp psoriasis over 8 weeks, but the patients studied were mainly White and non-Hispanic. The aim of this study was to evaluate the efficacy and safety of the two-compound scalp formulation in the treatment of scalp psoriasis in Hispanic/Latino and Black/African American patients. A total of 99 Hispanic/Latino and 78 Black/African American patients were randomized double-blind in a 3 : 1 ratio to 8 weeks of once daily treatment of scalp psoriasis with either the two-compound scalp formulation (n = 135) or its vehicle (n = 42). In the two-compound group, 71.9% of patients had cleared or minimal disease at week 8 by the investigator's global assessment compared to 40.5% in the vehicle group (odds ratio 3.30; 95% CI 1.62-6.72; P < 0.001). For the five secondary efficacy response criteria, three (total sign score, thickness of scalp psoriasis, patient's global assessment) showed that two-compound scalp formulation was statistically significantly more effective than its vehicle, and the other two (redness and scaliness of scalp psoriasis) approached statistical significance in favor of the two-compound scalp formulation. There was no statistically significant difference (P = 1.00) between the percentage of patients with adverse reactions in the two-compound group (7.0%) and the vehicle group (7.9%). The two-compound scalp formulation is safe and effective in the treatment of scalp psoriasis over 8 weeks in Hispanic/Latino and Black/African American patients.
