A UV source of low-intensity output with peak effective emission in the 300 to 320-nm range, termed low-intensity selective UV phototherapy (LISUP), is being advocated for home phototherapy for psoriasis. Twenty patients with plaque-type psoriasis were treated three times a week as outpatients with this unit; the results were compared with those found in a similar group of 20 outpatients treated previously three times a week with a proved and effective protocol using erythemogenic exposures to a conventional UV-B source. Emollients were the only topical agents used during therapy. Eight patients had clearing and five others showed improvement with LISUP. Eighteen patients had clearing and one showed improvement with the UV-B protocol. We found LISUP less frequently effective when used three times a week in clearing plaque-type psoriasis. Therefore, we recommend a trial of this unit before purchase by the patient.
一种低强度输出的紫外线源，其峰值有效发射波长在300至320纳米范围内，称为低强度选择性紫外线光疗法（LISUP），现被推荐用于银屑病的家庭光疗。20例斑块型银屑病患者作为门诊患者，使用该设备每周接受三次治疗；将结果与另一组20例门诊患者的结果进行比较，这组患者此前每周使用传统UV-B光源进行三次致红斑照射的有效方案进行治疗。治疗期间仅使用润肤剂作为外用药物。8例患者病情完全清除，另外5例使用LISUP治疗后有所改善。18例患者病情完全清除，1例使用UV-B方案治疗后有所改善。我们发现，每周使用三次LISUP清除斑块型银屑病的效果较差。因此，我们建议患者在购买该设备前先试用。
