Itch is an unpleasant symptom, affecting many dermatological patients. Studies investigating the occurrence and intensity of itch in dermatological patients often focus on a single skin disease and omit a control group with healthy skin. The aim of this multi-centre study was to assess the occurrence, chronicity and intensity (visual analogue scale 0-10) of itch in patients with different skin diseases and healthy-skin controls. Out of 3,530 dermatological patients, 54.3% reported itch (mean ± standard deviation itch intensity 5.5 ± 2.5), while out of 1,094 healthy-skin controls 8% had itch (3.6 ± 2.3). Chronic itch was reported by 36.9% of the patients and 4.7% of the healthy-skin controls. Itch was most frequent (occurrence rates higher than 80%) in patients with unclassified pruritus, prurigo and related conditions, atopic dermatitis and hand eczema. However, many patients with psychodermatological conditions and naevi also reported itch (occurrence rates higher than 19%).
瘙痒是一种令人不适的症状，影响许多皮肤科患者。研究瘙痒在皮肤科患者中的发生和强度的研究通常集中在单一的皮肤病上，而忽略了有健康皮肤的对照组。本多中心研究的目的是评估不同皮肤病患者和健康皮肤对照者瘙痒的发生、慢性和强度（视觉模拟评分 0-10）。在 3530 名皮肤科患者中，54.3%报告有瘙痒（平均±标准差瘙痒强度 5.5±2.5），而 1094 名健康皮肤对照者中 8%有瘙痒（3.6±2.3）。36.9%的患者和 4.7%的健康皮肤对照者报告有慢性瘙痒。未分类瘙痒、瘙痒症和相关疾病、特应性皮炎和手部湿疹患者瘙痒最常见（发生率高于 80%）。然而，许多精神皮肤病和痣患者也报告有瘙痒（发生率高于 19%）。
