PUVA therapy was originally developed as a treatment for psoriasis. PUVA (psoralen and ultraviolet A radiation) treatment has been used for decades to treat severe psoriasis. Psoralens are chemicals found in certain plants that have the ability to absorb ultraviolet light in the UVA portion of the solar spectrum. PUVA is also of benefit in treating vitiligo, mycosis fungoides (cutaneous T-cell lymphoma), and graft versus host disease. The ability of tanning beds to treat psoriasis was compared on the basis of their UVB output, one with a UVB output of 4. Concurrent use of tanning beds and psoralen may be potentially used in hand eczema due to the low body surface area involved, as patients would only need to expose their hands to the tanning bed radiation. With minimal erythemal dosing of UVA light noted to be 10 100 J/cm2 16 commercial tanning beds could be used to deliver therapeutic doses of UVA light in the treatment of cutaneous T cell lymphoma, though we found no reported cases of this therapeutic approach. Aetna considers psoralens and ultraviolet A light (PUVA) treatments medically necessary for the following conditions after conventional therapies have failed:. For narrow-band UVB phototherapy for vitiligo, see CPB 0422 – Vitiligo. The use of UVA tanning salon treatments in the therapy of psoriasis is usually unsuccessful and is extremely unwise with concomitant psoralen and drug therapy.
The most commonly prescribed psoralen is methoxsalen (8-methoxypsoralen) but 5-methoxypsoralen and trisoralen are sometimes used. The part to be treated is soaked in this solution prior to exposure to UVA emitted from special fluorescent lamps. Bathwater PUVA is used to treat inflammatory skin disorders, mainly:. It is most often prescribed for psoriasis or eczema affecting the hands and feet. Phototherapy is the use of UV radiation in the treatment of skin disease. High-dose UVA-1 is no longer widely used. The first report on the use of the excimer laser to treat psoriasis goes back to 1997. Desydrotic hand eczema. UV is widely used by dermatologists in the treatment of certain skin diseases like Psoriasis and Vitiligo. This medication called psoralen, giving rise to the acronym PUVA, makes the skin more sensitive and responsive to. It is widely used in PUVA (Psoralen + UVA) treatment for psoriasis, eczema, vitiligo, and cutaneous T-cell lymphoma.
PsoralenIt is widely used in PUVA (Psoralen + UVA) treatment for psoriasis, eczema, vitiligo, and cutaneous T-cell lymphoma. Photochemotherapy (PUVA) is a type of ultraviolet radiation (UVA). PUVA is a combination treatment, which consists of Psoralens (P) and then exposing the skin to long wave UVA. PUVA is useful for patients with various skin disorders, including psoriasis, dermatitis, polymorphic light eruption, and mycosis fungoides. The effect of PUVA on the long-term prognosis of CTCL is unknown. Easy to use system interface for UVA and UVB settings as well as MED and MPD automatic Phototest mode.

This document addresses the use of home ultraviolet light (UV) therapy to treat various skin conditions. Pityriasis lichenoides is a rare collection of skin disorders that have been reported to progress to cutaneous lymphoma or an ulceronecrotic presentation, both of which carry a significant risk of mortality. There are several treatment options currently used, and the UVB phototherapy has become widely accepted as an important tool in the management of these conditions (Wang, 2010). One type of photochemotherapy known as PUVA (Psoralen with UVA) involves the topical or oral administration of psoralen (a potent photosensitizing drug), followed by exposure to varying doses of UVA light. I n recent years, photomedicine, the therapeutic use of UV radiation and visible light, has become a critical weapon in the war against skin disorders. Researchers and clinicians have developed a wide range of phototherapeutic techniques to treat a variety of conditions, including psoriasis, vitiligo and cutaneous T-cell lymphoma. Bath-PUVA and combinations with other topical and systemic treatment modalities can be used to either reduce. Mycosis fungoides (cutaneous T-cell lymphoma) responds well to either broadband or narrowband UVB; however, Dr.
