Three age- and sex-matched groups of 30 patients with chronic plaque psoriasis were treated by photochemotherapy (PUVA). Groups I and II received routine maintenance PUVA therapy at different intervals and Group III had no maintenance treatment. The remission time after the clearance treatment with PUVA is compared with the total cumulative dose of long wave ultraviolet light (UVA). A lower mean dose of UVA (51.0 +/- 1.7 joules/cm(2)) in Group III (no maintenance PUVA) achieved a comparable remission period to that after larger cumulative doses following routine maintenance therapy (87.8 +/- 4.9 and 77.0 +/- 4.1 joules/cm(2) in Groups I and II).
将30例慢性斑块状银屑病患者按年龄和性别匹配分为三组,接受光化学疗法(补骨脂素加长波紫外线,PUVA)治疗。第一组和第二组以不同间隔接受常规维持性PUVA治疗,第三组不进行维持治疗。比较了PUVA清除治疗后的缓解时间与长波紫外线(UVA)的总累积剂量。第三组(无维持性PUVA)较低的平均UVA剂量(51.0±1.7焦耳/平方厘米)所达到的缓解期,与常规维持治疗后较大累积剂量(第一组和第二组分别为87.8±4.9和77.0±4.1焦耳/平方厘米)后的缓解期相当。
