Narrow-band UVB has been reported to be efficacious in patients with vitiligo. The epidermis of patients with vitiligo showed reduction in the levels of catalase, in association with high levels of hydrogen peroxidase (H2O2) that is toxic for melanocytes. Based on these findings, we studied the efficacy and safety of a topical gel containing catalase and superoxide dismutase (Vitix) in combinat...

BACKGROUND/PURPOSE There is no definite cure for vitiligo; however, treatment responses with photobiological modalities are quite acceptable. Of all these, narrow-band UVB phototherapy was proposed rather recently. Calcipotriol has been shown to have stimulating activity on melanogenesis besides immunomodulatory and anti-inflammatory effects. This study was performed to determine whether adding...

The first report of the use of ‘phototherapy’ in the treatment of skin disorders dates from 1400 BC from India when patients with vitiligo were given certain plant extracts (whose active ingredients included psoralens) and then exposed to the sun. The real interest in the use of ultraviolet (UV) irradiation in the treatment of various skin diseases started in the 19 century when Niels Finsen re...

Narrow-band UVB (NB-UVB) is light over a very narrow band of wavelengths (around 311 nm) that is concentrated in the therapeutic range and minimally in the sunburn range. It has therefore become the phototherapy treatment of choice for skin diseases. The minimal erythema dose (MED) on canine skin for standardizing dosage schedules in NB-UVB treatment and histopathological analyses were performe...

BACKGROUND The treatment of vitiligo remains a challenge. OBJECTIVE The purpose of this article is to review our results and experience with narrow-band ultraviolet (UV) B phototherapy for vitiligo. METHODS This is a retrospective analysis of our experience and results with patients with vitiligo who were treated with narrow-band UVB between November 1998 and November 1999. Narrow-band UVB ...

In patients with severe chronic atopic dermatitis (AD), both photochemotherapy [psoralen ultraviolet A (PUVA)] and narrow-band (TL-01) UV B phototherapy have been reported to be very effective. As no data exist on the relative therapeutic efficacy of these two regimens, we performed a randomized investigator-blinded half-side comparison study on 12 patients with severe chronic AD. Half-side irr...

Background: Chronic graft versus host disease (cGVHD) is a major cutaneous complication of bone marrow transplantation (BMT). Although milder forms of this process may be associated with a lower incidence of tumor recurrences, it is mandatory to develop a more efficient and less harmful therapeutic approach.Methods: This case-series study enrolled 7 patients diagnosed w...

BACKGROUND Only a few clinical trials have been performed on the treatment of generalized vitiligo in children. Recently, narrow-band UVB therapy has been reported to be an effective and safe therapeutic option in adult patients with vitiligo. OBJECTIVE We studied the efficacy and safety of UVB (311 nm) therapy in children with generalized vitiligo and evaluated the effect of the therapy on t...
