Successful treatment of scalp psoriasis with Dovobet? ointment 使用得肤宝成功治疗头皮银屑病
Emerson R M, Howlett C Br J Dermatol 2004; 151(Suppl. 68): 52-53 Scalp psoriasis is a common problem in the general population and many patients experience both psychological and social embarrassment (van de Kerkhof PCM, de Hoop D, de Korte J, Kuipers MV. Scalp psoriasis, clinical presentations and therapeutic management. Dermatology 1998; 197: 326–34). A range of topical treatments is available, and treatments are often used in combination. Despite this, many patients suffer from suboptimal disease control. Dovobet ointment (Leo, Princes Risborough, U.K.; calcipotriol 50 microg g-1 and betamethasone dipropionate 0.5 mg g-1) has shown good efficacy in the treatment of body psoriasis (Kaufmann R, Bibby AJ, Bissonnette R et al. A new calcipotriol ? betamethasone dipropionate formulation (Daivobet?) is an effective once-daily treatment for psoriasis vulgaris. Dermatology 2002; 205: 389–93) but is not licensed for use on the scalp. We undertook an observational, uncontrolled, pilot study on the effectiveness of Dovobet ointment in the treatment of scalp psoriasis. Nine patients with scalp psoriasis were enrolled. All patients had been referred to secondary care having failed on one or more topical preparations prescribed by their general practitioner. Their mean age was 36 years, and mean duration of scalp psoriasis 8?6 years. Patients were graded for extent of scalp involvement (0–100%), itch (10-point scale), plaque thickness and scaliness (very severe, severe, moderate, mild and very mild). Assessments were made before treatment, at 1 week, and 4 weeks after starting treatment. Patients were also asked to assess the overall response to treatment at follow-up. Before treatment, seven were recorded as having very severe ? severe plaque thickness, eight very severe ? severe scaliness, and seven had > 50% scalp involvement. All patients applied Dovobet ointment at 18.00–19.00 h each evening and washed it out 4 h later, for a total duration of 4 weeks. After 1 week, six patients achieved marked improvement of their scalp psoriasis with decreased levels of itch, a reduction in disease extent (only two patients >50% surface area involvement), reduced plaque thickness and scaliness. By 4 weeks, seven patients reported marked overall improvement, one patient slight improvement and one patient failed to attend for assessment (telephone enquiry demonstrated lack of efficacy of therapy). Compliance with treatment was excellent; however, patients reported that the ointment made the hair very greasy, and was difficult to wash out. In conclusion, this is the first study to suggest that Dovobet ointment is an effective treatment for scalp psoriasis.
