Being exposed to house dust mites intensifies atopic dermatitis. This study has investigated the contamination rate with mites in patient's residential home with atopic dermatitis.
In this cross-sectional study, 40 patients took part with atopic dermatitis (positive or negative for mites by prick Dermal Test). Samples were collected from 3 locations (living room, bedroom and bed) by vacuum cleaner. Dust samples (transferred to freezer -20 °C) were examined by direct method and flotation. The data were analyzed using statistical SPSS vr.20 software.
Twenty patients of positive prick test included 8 (40%) male and 12 (60%) female. The results of direct observation of mites: 7 cases (35%) in bedding sheets, 6 cases (30%) bedrooms' carpet, 3 cases (15%) living room's carpet. Twenty patients of negative prick test included 8 (40%) male and 12 (60%) female. Only mites were found (5%) in living room's carpets of negative prick test patients. was more frequent than e. (98% vs 83%).
Fifty-five percent of residential homes of prick test positive patients and only 5% of residential homes of prick test negative patients were positive for mite. Sunshine provided home had fewer mites than home where sunshine is not provided. Prick test positive patients used handmade carpets more than machine made ones. In positive prick test patients, mites were found in bed sheet and bedroom's carpet more than negative prick test patient's sheets and carpets.
接触屋尘螨会加重特应性皮炎。本研究调查了特应性皮炎患者住宅中的螨污染率。
在这项横断面研究中，40例特应性皮炎患者参与（通过皮肤点刺试验螨检测呈阳性或阴性）。用真空吸尘器从3个地点（客厅、卧室和床）采集样本。将灰尘样本（转移至-20°C冰箱）通过直接法和漂浮法进行检测。使用统计软件SPSS vr.20对数据进行分析。
20例点刺试验阳性患者中，男性8例（40%），女性12例（60%）。螨的直接观察结果：床单上7例（35%），卧室地毯6例（30%），客厅地毯3例（15%）。20例点刺试验阴性患者中，男性8例（40%），女性12例（60%）。在点刺试验阴性患者的客厅地毯中仅发现螨（5%）。 比 更常见（98%对83%）。
点刺试验阳性患者住宅中55%螨检测呈阳性，而点刺试验阴性患者住宅中仅5%螨检测呈阳性。有阳光照射的家中螨比没有阳光照射的家中少。点刺试验阳性患者使用手工地毯多于机制地毯。在点刺试验阳性患者中，床单和卧室地毯中发现螨的情况比点刺试验阴性患者的床单和地毯中更常见。
