摘要： 目的 探讨湿疹和特应性皮炎(AD)皮损处金黄色葡萄球菌(金葡菌)及其他细菌的定植情况,评价抗菌药物与糖皮质激素联合用药的疗效。方法 采用多中心、随机、双盲试验,在筛选日及治疗后第7、14和28天对皮损评分,并在皮损和非皮损处分离细菌。试验组外用抗菌药物和糖皮质激素,对照组外用基质和糖皮质激素。结果 共入选患者327例,湿疹208例,AD119例。湿疹皮损处细菌的阳性率为70.19%,金葡菌占47.26%;非皮损部位细菌阳性率为32.69%,金葡菌占27.94%。AD皮损处细菌阳性率为74.79%,金葡菌占79.78%;非皮损部位细菌阳性率为34.45%,金葡菌占80.49%。湿疹和AD皮损部位金葡菌的定植量均高于非皮损部位(P<0.01,P<0.05),细菌的定植量与皮损的严重程度呈正相关。两组患者治疗后总体疗效无明显差异(P>0.05),但湿疹临床症状评分指数>8分者及AD评分指数>7分者,在治疗的第7天,试验组与对照组的症状评分指数改善率存在显著差异(P<0.05),在治疗的第14天和第28天,两组差异均无显著性(P>0.05)。结论 湿疹和AD患者皮损部位细菌的检出率和金葡菌的带菌率均明显增高,说明金葡菌与湿疹皮炎的关系密切,早期联用抗菌药物可提高疗效。

Abstract: Objective To investigate the colonization features of Staphylococcus aureus (S. aureus) in the skin lesions of eczema and atopic dermatitis (AD), and to evaluate the therapeutic effect of combination topical treatment with mupirocin and hydrocortisone butyrate. Methods A multicentre, double-blind randomized trial was conducted. The SCORAD was evaluated on day 1, 7, 14 and 28. Swabs for bacterial isolation were taken from the lesional skin and non-lesional skin. A combination topical therapy with mupirocin ointment and hydrocortisone butyrate ointment was used in treatment group, with vehicle ointment and hydrocortisone butyrate ointment as a control. Results Three hundred and twenty seven patients were enrolled in the study, including 208 patients with eczema and 119 patients with atopic dermatitis. Bacteria were isolated from 70.19% of lesional skin and 32.69% of non-lesional skin of patients with eczema, in which S. aureus accounted for 47.26% and 27.94% respectively. Bacteria were isolated from 74.79% of the lesional skin and 34.45% of non-lesional skin of patients with atopic dermatitis, in which S. aureus accounted and 79.78% or 80.49% respectively. The amount of S. aureus colonized was markedly higher in the lesional skin than that in non-lesional skin, either in eczema patients or in atopic dermatitis (P<0.01, P<0.05), which was positively correlated with the severity of the lesion. There was no difference in the gross therapeutic effect between combination therapy group and control group after treatment. However, in the eczema patients with clinical score more than 8 or in the AD patients with clinical score more than 7, the therapeutic effect of the combination therapy group was superior to that in the control group (P<0.05) seven days after theatment. There were no differences between the two groups 14 days and 28 days after treatment (P>0.05). Conclusions The bacterial colonization, especially S. aureus, is more frequently dectected in the lesional skin of eczema patients and AD patients than that in the non-lesional skin, which may be related in the pathogenesis of eczema and AD. And, early application of combination therapy with topical antibiotics and corticosteroids is beneficial to the patients.
