特应性皮炎患者皮肤马拉色菌菌量及其与病情严重程度相关性研究
[摘要] 目的 检测特应性皮炎（AD）患者皮肤马拉色菌菌量，探讨其与病情严重程度的相关性。 方法 选取成都医学院第一附属医院2017年4～9月就诊的轻中重度AD患者各20例，采集其面部、上肢皮损区和非皮损区以及20例健康对照者相应区域的皮肤鳞屑标本，采用真菌荧光染色法在高倍镜下记录马拉色菌的密度，并分析马拉色菌密度与病情严重程度的相关性。 结果 轻中重度AD患者面部皮损区、非皮损区马拉色菌密度均明显高于上肢皮损区、非皮损区（P < 0.05），轻中重度AD患者各部位马拉色菌密度均明显高于健康对照者相应区域（P < 0.05），AD患者各部位马拉色菌密度与病情严重程度均无相关性（P > 0.05）。 结论 AD患者皮肤马拉色菌菌量与部位有关，与病情严重程度无关。

[Abstract] Objective To detect the amount of Malassezia in the skin of patients with atopic dermatitis （AD）， and explore its correlation with the disease severity. Methods 20 mild， 20 moderate and 20 severe AD patients were selected from the First Affiliated Hospital of Chengdu Medical College from April to September 2017. Skin scales were collected as samples from the lesion and non lesion areas on the face and upper limb of AD patients as well as the corresponding areas of 20 healthy control subjects. The density of Malassezia was recorded at high magnification by fluorescent staining method. Then the correlation between the density of Malassezia and the disease severity was analyzed. Results The density of Malassezia in the lesion and non lesion areas on the face of the mild， moderate and severe AD patients was significantly higher than those of the upper limbs （P < 0.05）. The density of Malassezia in each skin area of mild， moderate and severe AD patients was significantly higher than that of healthy control su...
