Ultraviolet phototherapy for pruritus

Ultraviolet-based therapy has been used to treat various pruritic conditions including pruritus in chronic renal failure, atopic dermatitis, HIV, aquagenic pruritus and urticaria, solar, chronic, and idiopathic urticaria, urticaria pigmentosa, polycythemia vera, pruritic folliculitis of pregnancy, breast carcinoma skin infiltration, Hodgkin's lymphoma, chronic liver disease, and acquired perforating dermatosis, among others. Various mechanisms of action for phototherapy have been posited. Treatment limitations, side effects, and common dosing protocols are reviewed.     

Ultraviolet radiation and immunosuppression

Ultraviolet (UV) radiation is a complete carcinogen. The effects of UV radiation are mediated via direct damage to cellular DNA in the skin and suppression of image surveillance mechanisms. In the context of organ transplantation, addiction of drugs which suppress the immune system add greatly to the carcinogenicity of UV radiation. This review considers the mechanisms of such effects.     

Ultraviolet A in vitiligo

Both types of Ultraviolet (UV), UVB (290-320 nm) and UVA (320-400 nm), produce increased pigmentation or tanning. However, no evaluation of UVA alone in the treatment of vitiligo has been reported. Therefore, it was the purpose of this work to study the pigmentogenic effect of UVA (5 and 15 J/cm(2)) in vitiligo. The study included 20 randomly selected patients with vitiligo involving more than 30% of the body surface area with a bilateral/symmetrical distribution. They were equally divided into two groups each of 10 patients. All patients received three weekly sessions of UVA, 15 J/cm(2) in group I and 5 J/cm(2) in group II, a total of 48 sessions over 16 weeks. Overall pigmentation of 60% and above was recorded in 50% and 10% of patients in groups I and II, respectively. We conclude that broadband UVA alone, without psoralens, and in appropriate doses may be of important therapeutic value in vitiligo.     

Ultraviolet A1 phototherapy

Long-wavelength ultraviolet A (340-400 nm; UVA1) therapy is currently available in only a few dermatology departments. Equipment capable of delivering this waveband has been available since 1981, but it is only over the past decade that increasing numbers of studies assessing the potential of this as a therapy have been published. High-dose UVA1, which requires expensive and space-occupying apparatus, is effective as a monotherapy for acute flares of atopic dermatitis, but it has not yet been formally assessed as an adjunct, rather than as an alternative to conventional therapies including potent and very potent topical corticosteroids. Low-dose (which can be administered using a standard phototherapy cubicle fitted with appropriate lamps) and medium-dose UVA1 may be less effective for this indication. Another condition for which UVA1 is effective, and is particularly promising because we have no reliably effective treatment already, is localized scleroderma. It also appears to be effective in systemic lupus erythematosus (although it is not yet clear when it is indicated, and its safety needs to be assessed in more patients) and in polymorphic light eruption (although there have been no studies suggesting that UVA1 will have any advantages over standard prophylactic phototherapies). Open studies and case series suggest that UVA1 may prove beneficial for various other diseases, including cutaneous T-cell lymphoma, lichen sclerosus, keloids, systemic sclerosis and hand dermatitis. In the centres where it is available, UVA1 has already proved a useful addition to the range of phototherapies previously available. However, much more research is needed to confirm its efficacy for many of its potential indications, and to determine when and how it should be used.
