Abstract

The pattern of itching in patients with atopic dermatitis has not been systematically studied. Therefore, this study aimed to assess the pattern of itching in adults with atopic dermatitis using questionnaires to assess for a circadian rhythm of itching in participating patients at a single institution (n = 241). A self-report questionnaire was used to assess circadian rhythm and intensity of itching in patients. In addition, the patients' disease severity (Eczema Area and Severity Index [EASI]) and quality of life (Dermatology Life Quality Index [DLQI]) were assessed. Itching occurred most frequently (74.69%) and with the greatest severity (62.66%) between 20:00 and 00:00, and the least number of patients (25.31%) experienced itching between 04:00 and 08:00. The DLQI and EASI scores both correlated with the average and maximum itch intensity (r = 0.582, r = 0.533, respectively; r = 0.539, r = 0.517, respectively; p < 0.001). The DLQI and EASI scores were associated with average itch intensity (B = 0.179, B = 0.204, respectively; 95% CI: 0.112 to 0.246, 95% CI: 0.096 to 0.313, respectively; p < 0.001), and the EASI score was associated with males and family history (B = 0.285, B = 0.287, respectively; 95% CI: 0.094 to 0.476, 95% CI: 0.096 to 0.478, respectively; p = 0.003). Adult patients with atopic dermatitis exhibited a circadian rhythm of itching; these study results could positively impact treatment approaches.

241 名成人特应性皮炎患者瘙痒的昼夜节律:横断面研究
特应性皮炎患者的瘙痒模式尚未得到系统研究。因此,本研究旨在评估成人特应性皮炎患者的瘙痒模式,采用问卷调查的方式,对一家机构的参与患者(n = 241)的瘙痒昼夜节律进行评估。该研究采用自我报告问卷来评估患者瘙痒的昼夜节律和强度。此外,还评估了患者的疾病严重程度(湿疹面积和严重程度指数[EASI])和生活质量(皮肤病生活质量指数[DLQI])。瘙痒发生频率最高(74.69%),严重程度最重(62.66%),发生时间为 20:00 至 00:00,而在 04:00 至 08:00 出现瘙痒的患者最少(25.31%)。DLQI 和 EASI 分数均与平均瘙痒强度和最大瘙痒强度相关(分别为 r = 0.582 和 r = 0.533;r = 0.539 和 r = 0.517; p
