Background: Broad-band UVB alone or in combination with different topical drugs (anthralin, calcipotriol), systemic PUVA and bath-PUVA therapy are very effective and well-established treatment modalities for psoriasis. Objective: The aim of this retrospective study was to assess which of these routinely applied phototherapeutic modalities might be most effective and safe for the treatment of plaque-type psoriasis. Methods: Patients (n = 203) with moderate to severe (pretreatment Psoriasis Area and Severity Index score between 12 and 35) chronic plaque-type psoriasis treated between 1992 and 1998 at our department with either UVB (with/without anthralin or calcipotriol; n = 97), systemic PUVA (n = 19) or bath-PUVA therapy (n = 87) were evaluated for efficacy, duration of treatment, number of treatments necessary for complete remission (CR), cumulative light dose, side effects of therapy and duration of remission after therapy. Results: No statistically significant difference comparing the efficacy of bath-PUVA (CR in 72.4%), PUVA (CR in 89.5%) and UVB phototherapy (CR in 69.1%) was found. Although the duration of therapy was significantly longer for bath-PUVA (66 +/- 42 days) as compared to UVB treatment (50 +/- 27 days), the mean number of treatments did not differ significantly be-tween bath-PUVA (28 +/- 12), UVB therapy(30 +/- 12) and PUVA(26 +/- 13). Significantly fewer side effects of phototherapy were observed with bath-PUVA (14.9%) therapy compared to UVB treatment (30.9%). Also, the duration of remission after successful therapy was significantly longer for bath-PUVA (8.4 +/- 3.5 months) as compared to UVB phototherapy(5.1 +/- 4.2 months). Conclusion: Bath-PUVA therapy has some advantages over UVB phototherapy in the treatment of psoriasis: fewer UV-related acute side effects and a longer period of remission after therapy. However, the choice of treatment with either UVB, bath-PUVA or systemic PUVA should also be based on a history of previous response to treatment and patient considerations, including compliance and responsibility for following the precautions to avoid potential side effects.
