About

The aim of this study is to evaluate the influence of two concentrations of methotrexate on vitiligous lesions in patients with non-segmental vitiligo

Full description

Methotrexate, synthesized in the 1950s as an anticancer drug with an antiproliferative effect, is currently one of the most commonly used immunosuppressive agents in dermatology. The use of small, non-oncological doses has revealed its anti-inflammatory properties, including the impact on a number of cytokines involved in the pathogenesis of autoimmune diseases. It has been shown that treatment with methotrexate reduces the levels of TNF-alpha-producing T cells, while the number of IL-10 producing T cells increases. Methotrexate also inhibits the synthesis of interferon-γ. The above considerations justify the use of topical methotrexate in patients with vitiligo in order to obtain repigmentation.

A study has been designed as a single-center, randomized, double-blind, placebo-controlled pilot study with the enrollment of up to 100 active non-segmental vitiligo patients presenting with vitiligous lesions on both upper and lower limbs. Clinical effects of gel containing 1% methotrexate or 0.5% methotrexate applied on a preselected limb will be assessed in comparison with vehicle ointment applied on the opposite limb. All study participants will undergo clinical evaluation using Body Surface Area (BSA) and Vitiligo Area Scoring Index (VASI) scales at baseline, week 4, week 8 and week 12 time points. Precise assessment of skin lesions will be performed using photographic documentation obtained during each study visit and processed with NIS-Elements software.
