The aim of this post hoc analysis was to evaluate whether treatment of patients with atopic dermatitis (AD) with pimecrolimus cream 1% can decrease the development of flares necessitating the use of a topical corticosteroid on the face and thus reduce the need for use of topical corticosteroids in this sensitive skin area.
In a controlled, double-blind, multicentre study, 140 patients, aged 2 to 17 years, with facial involvement and mild to moderate disease after treatment of the initial flare with prednicarbate 0.25% cream were randomized to an intermittent treatment with pimecrolimus cream 1% twice daily or vehicle for 24 weeks. If a flare occurred, defined as an exacerbation (unacceptable severity of itching/scratching or onset of oozing) not controlled by study medication, patients were treated with prednicarbate 0.25% cream instead.
Patients in the vehicle group needed prednicarbate treatment on the face on 20.7% of the days vs. 11.7% of the study days in the pimecrolimus group (P = 0.0024). Fifty per cent of patients in the pimecrolimus group had no flare on the face during the treatment period compared with 37.5% of patients in the vehicle group (P = 0.012). The median time to first flare in pimecrolimus-treated patients was twice as long as in patients receiving vehicle (138 vs. 68 days, P = 0.01). Three adverse events (one case of skin burning) suspected to be related to use of the study medication were reported for three patients (3.9%) in the pimecrolimus group.
Long-term intermittent treatment of facial AD in children and adolescents with pimecrolimus cream 1% does significantly reduce the need for topical corticosteroids.
本事后分析的目的是评估用1%吡美莫司乳膏治疗特应性皮炎(AD)患者是否能减少面部需要使用外用糖皮质激素的皮疹发作,从而减少在这个敏感皮肤区域使用外用糖皮质激素的需求。
在一项对照、双盲、多中心研究中,140名年龄在2至17岁、面部受累且在用0.25%丙酰倍他米松乳膏治疗初始皮疹后患有轻至中度疾病的患者,被随机分为每日两次接受1%吡美莫司乳膏间歇治疗或接受赋形剂治疗,为期24周。如果发生皮疹发作,定义为病情加重(瘙痒/抓挠严重程度不可接受或出现渗液)且未被研究药物控制,则改用0.25%丙酰倍他米松乳膏治疗患者。
赋形剂组患者面部需要丙酰倍他米松治疗的天数占20.7%,而吡美莫司组为研究天数的11.7%(P = 0.0024)。吡美莫司组50%的患者在治疗期间面部未出现皮疹发作,而赋形剂组为37.5%(P = 0.012)。接受吡美莫司治疗的患者首次皮疹发作的中位时间是接受赋形剂治疗患者的两倍(138天对68天,P = 0.01)。吡美莫司组有3名患者(3.9%)报告了3起疑似与使用研究药物有关的不良事件(1例皮肤烧灼感)。
用1%吡美莫司乳膏对儿童和青少年面部AD进行长期间歇治疗确实能显著减少外用糖皮质激素的需求。
