Ten psoriasis patients who underwent a 4-week heliotherapy period in the Canary Islands were treated with ultraviolet B (UVB) phototherapy at relapse, 2-24 months later. In both settings, psoriasis improvement was monitored using a psoriasis severity index (PSI), and UV exposure was recorded with polysulphone films. In the 8 patients that could be evaluated, a median healing rate of 94% was recorded in the heliotherapy period, with a median cumulative UV dose of 46 erythemal units (EU). In the UVB phototherapy, a median improvement rate of 86% was found after a median cumulative UV dose of 112 EU. It is concluded that, on an erythemal UV dose basis, heliotherapy was more effective than UVB phototherapy in treating psoriasis.
10名在加那利群岛接受了为期4周日光疗法的银屑病患者，在复发时（2至24个月后）接受了紫外线B（UVB）光疗。在这两种情况下，均使用银屑病严重程度指数（PSI）监测银屑病的改善情况，并用聚砜膜记录紫外线暴露情况。在可评估的8名患者中，日光疗法期间的愈合率中位数为94%，累积紫外线剂量中位数为46红斑单位（EU）。在UVB光疗中，累积紫外线剂量中位数为112 EU后，改善率中位数为86%。得出的结论是，以红斑紫外线剂量为基础，日光疗法在治疗银屑病方面比UVB光疗更有效。
