Comparison of psoralen-UVB and psoralen-UVA photochemotherapy in the treatment of psoriasis

Psoralen–ultraviolet A therapy vs. psoralen–ultraviolet B therapy in the treatment of plaque‐type psoriasis: our experience with Fitzpatrick skin type IV

“…Our results are consistent with those of de Berker et al 6 . who compared conventional PUVA with PUVB therapy using a narrow‐band (311 ± 2 nm) UVB exposure (TL‐01; Philips) in the treatment of plaque‐type psoriasis.…”

“…found that oral psoralen with UVB is more erythemogenic and efficacious in psoriasis than UVB alone. Recently, de Berker et al 6 . compared PUVA and PUVB in the treatment of psoriasis.…”

Phototherapy with Narrowband vs Broadband UVB

“…Anecdotal reports describe equal efficacy of psoralens in combination with nUVB when compared to PUVA, although it is unclear to what extent improvement was due to nUVB radiation alone (82)(83)(84). The combination of bath-PUVA plus additional nUVB has also been described with nUVB enhancing the phototoxic and therapeutic activities of bath-PUVA (85).…”

Comparative efficacy of narrow-band ultraviolet B phototherapy alone and its combination with topical 8-methoxypsoralen in psoriasis

“…de Berker et al [12] reported the results of a randomized trial in patients with plaque-type psoriasis comparing conventional PUVA with psoralenUVB therapy in 100 patients. They concluded that psoralenUVB treatment of psoriasis is as effective as PUVA.…”
