Psoralen UVA (PUVA) and narrow-band UVB (NBUVB) chemophototherapy are treatment options for psoriasis.
To compare the effectiveness of NBUVB with PUVA in Vietnamese psoriasis patients.
We conducted a non-randomized trial on 60 patients with plaque-type psoriasis (30 NBUVB, 30 PUVA). Both regimens were thrice-weekly. The extent of lesion was assessed by the Psoriasis Area Severity Index (PASI). Clearance was defined as a ≥ 75% reduction in a follow-up PASI score from baseline. Patients with clearance were followed-up until 6 months after stopping treatment. Relapse was defined as 50% or more of the original extent.
The proportion of patients achieving PASI75 was comparable (76.7% in NBUVB versus 80% in PUVA; p > 0.05). Patients in both groups had a similar number of sessions to achieve clearance but patients in the PUVA group exposed to a significantly higher cumulative UV dose. After six months, the relapse rate was higher in the NBUVB group compared with in the PUVA group (p > 0.05).
Thrice weekly NBUVB is as effective as thrice weekly PUVA in treating psoriasis for Vietnamese patients.
补骨脂素长波紫外线（PUVA）和窄谱中波紫外线（NBUVB）化学光疗是治疗银屑病的方法。
比较NBUVB与PUVA对越南银屑病患者的疗效。
我们对60例斑块型银屑病患者进行了一项非随机试验（30例接受NBUVB治疗，30例接受PUVA治疗）。两种治疗方案均为每周3次。通过银屑病面积和严重程度指数（PASI）评估皮损范围。清除定义为随访时PASI评分较基线降低≥75%。对达到清除的患者随访至停止治疗后6个月。复发定义为皮损范围达到原来的50%或更多。
达到PASI75的患者比例相当（NBUVB组为76.7%，PUVA组为80%；p>0.05）。两组患者达到清除所需的治疗次数相似，但PUVA组患者接受的累积紫外线剂量明显更高。6个月后，NBUVB组的复发率高于PUVA组（p>0.05）。
对于越南患者，每周3次的NBUVB治疗银屑病的效果与每周3次的PUVA相当。
