Vitiligo: Treatment...

There are a number of ways to alter the appearance of vitiligo without addressing its underlying cause. In mild cases, vitiligo patches can be hidden with makeup or other cosmetic camouflage solutions. If the affected person is pale-skinned, the patches can be made less visible by avoiding sunlight and the sun tanning of unaffected skin. However, exposure to sunlight may also cause the melanocytes to regenerate to allow the pigmentation to come back to its original color.

Corticosteroids

The traditional treatment given by most dermatologists is corticosteroid cream.

Phototherapy

Phototherapy may also beneficial using exposure to long-wave ultraviolet (UVA) light from the sun or from UVA lamps, together with Psoralen, called "PUVA", can help in many cases. Psoralen can be taken in a pill 1-2 hours before the exposure or as a Psoralen bath or soaking the area before the exposure. Lately, PUVA has been replaced with exposure to Narrowband UVB light at a wavelength of 311-313 nanometers. This treatment does not involve Psoralen since the effect of the lamp is strong enough. The source for the UVB Narrowband UVB light can be special fluorecent lamps that treat large area in few minutes, or high power fiber-optic devices in a fraction of a second.

Studies have also shown that immunomodulator creams such as Protopic and Elidel also cause repigmentation in some cases, when used with UVB Narrowband treatments.

Alternatively, some people with vitiligo opt for chemical depigmentation, which uses 20% monobenzylether of hydroquinone. This process is irreversible and generally ends up with complete or mostly complete depigmentation.

Transplants

In late October of 2004, doctors successfully transplanted melanocytes to vitiligo affected areas, effectively repigmenting the region. The procedure involved taking a thin layer of pigmented skin from the patient's gluteal region. Melanocytes were then separated out and used to make a cellular suspension. The area to be treated was then ablated with a medical laser, and the melanocyte graft applied. Three weeks later, the area was exposed to UV light repeatedly for two months. Between 73 and 84 percent of patients experienced nearly complete repigmentation of their skin. The longevity of the repigmentation differed from person to person.
