全身性瘙痒是尿毒症最常见和持久的症状之一,原因尚不清楚。为了研究紫外线的疗效及其对皮肤钙、磷和镁含量的影响,本文调查了155例稳定的慢性血透析患者的瘙痒情况,对其中17例严重瘙痒患者作了单盲研究。同时对5例无瘙痒的透析患者和6名健康志愿者进行了研究。将17例瘙痒患者随机地分为两组:UVA(安慰剂)治疗组和UVB治疗组,血透析前二周全身照射,每周3次。6名健康志愿者用UVB全身照射,每周3次,共6次。
Systemic itching is one of the most common and persistent symptoms of uremia, the reason is not clear. In order to investigate the efficacy of UV light and its effects on calcium, phosphorus and magnesium levels in the skin, we investigated the pruritus in 155 patients with stable chronic hemodialysis and 17 patients with severe itch in a single-blind study. Five non-itch dialysis patients and six healthy volunteers were also studied. Seventeen patients with pruritus were randomly divided into two groups: UVA (placebo) -treated group and UVB-treated group. Whole body irradiation was performed two weeks before hemodialysis three times a week. Six healthy volunteers were exposed to UVB for 3 times a week for 6 times.
