Itch is common in psoriasis, adversely affecting health-related quality of life (HRQoL) and sleep.
We evaluated the efficacy of topical fixed-dose combination calcipotriol 50 μg/g plus betamethasone dipropionate 0.5 mg/g cutaneous foam (Cal/BD foam) on itch, itch-related sleep loss and HRQoL vs. foam vehicle.
We pooled data from three Phase II/III trials (NCT01536886/NCT01866163/NCT02132936) of Cal/BD foam vs. foam vehicle in adults with mild-severe psoriasis. For itch-related analyses, patients with baseline itch visual analogue scale (VAS) >40 (range 0-100) were analysed. Outcomes included the following: itch VAS reduction >40, ≥70% improvement in itch (Itch70) or itch-related sleep loss, 75% improvement in modified Psoriasis Area and Severity Index (excluding head; mPASI75) and Dermatology Life Quality Index (DLQI) scores 0/1 through 4 weeks.
Of 837 patients, 800 had baseline itch VAS >0 (Cal/BD foam, n = 610; foam vehicle, n = 190); 484 had baseline itch VAS >40. There was no correlation between itch VAS score and mPASI at baseline (R = 0.021). In patients with baseline itch VAS >40, more patients achieved itch VAS reduction >40 in the active vs. vehicle group from Day 5 onwards (Day 5: 57.5% vs. 40.2% [P < 0.05]; Week 4: 83.0% vs. 45.8% [P < 0.001]). More Cal/BD-foam-treated patients achieved Itch70 at Day 3 (34.2% vs. 22.5%; P < 0.05) through to Week 4 (79.3% vs. 38.1%; P < 0.001). In patients with baseline itch VAS >40 and sleep loss >20, improvements in itch-related sleep loss occurred at Week 1 and continued through 4 weeks. Itch-related improvements occurred before improvements in mPASI75. There were significant differences in the proportion of Cal/BD-foam- vs. foam-vehicle-treated patients with baseline DLQI >10 (n = 172 vs. n = 50) achieving DLQI ≤1 (25.0% vs. 4.0%; P = 0.001) and DLQI 0 (17.4% vs. 2.0%; P = 0.006) at Week 4.
Compared with foam vehicle, Cal/BD foam offers more rapid and effective itch relief, with associated significant improvements in sleep and DLQI.
瘙痒是银屑病的常见症状,会对健康相关生活质量(HRQoL)和睡眠产生不利影响。
评估固定剂量复方钙泊三醇 50μg/g 加倍他米松二丙酸酯 0.5mg/g 皮肤泡沫(Cal/BD 泡沫)与泡沫载体相比,在治疗瘙痒、瘙痒相关睡眠损失和 HRQoL 方面的疗效。
我们汇总了三项关于 Cal/BD 泡沫与泡沫载体在轻度至重度银屑病成人患者中的 II/III 期试验(NCT01536886/NCT01866163/NCT02132936)的数据。对于瘙痒相关分析,纳入基线瘙痒视觉模拟量表(VAS)>40(范围 0-100)的患者。主要疗效终点包括瘙痒 VAS 改善>40、瘙痒改善≥70%(Itch70)或瘙痒相关睡眠损失、改良银屑病面积和严重程度指数(不包括头部;mPASI75)和皮肤病生活质量指数(DLQI)评分改善至 0/1 分在 4 周内。
在 837 名患者中,800 名患者基线瘙痒 VAS >0(Cal/BD 泡沫组 n=610,泡沫载体组 n=190);484 名患者基线瘙痒 VAS >40。瘙痒 VAS 评分与基线时 mPASI 无相关性(R=0.021)。在基线瘙痒 VAS >40 的患者中,从第 5 天开始,活性治疗组较载体组有更多患者达到瘙痒 VAS 改善>40(第 5 天:57.5% vs. 40.2% [P<0.05];第 4 周:83.0% vs. 45.8% [P<0.001])。更多接受 Cal/BD 泡沫治疗的患者在第 3 天(34.2% vs. 22.5%;P<0.05)和第 4 周(79.3% vs. 38.1%;P<0.001)达到 Itch70。在基线瘙痒 VAS >40 和睡眠损失>20 的患者中,瘙痒相关睡眠损失在第 1 周开始改善,并持续至第 4 周。瘙痒改善先于 mPASI75 的改善。基线时 DLQI >10(n=172)的 Cal/BD 泡沫治疗患者与 DLQI≤1(25.0% vs. 4.0%;P=0.001)和 DLQI 0(17.4% vs. 2.0%;P=0.006)的比例显著高于泡沫载体治疗患者。
与泡沫载体相比,Cal/BD 泡沫能更迅速有效地缓解瘙痒,并显著改善睡眠和 DLQI。
