The existing treatment for vitiligo is as follows:
1. hormone therapy
(1) The system is mainly suitable for patients with generalized progressive vitiligo. The hormone is orally or intramuscularly injected to stabilize the leucoderma in the advancing stage as soon as possible.
(2) Local treatment, topical glucocorticoid is effective for treating limited vitiligo, but adverse reaction caused by long-term topical glucocorticoid should be noticed. The clinically commonly used medicines comprise halometasone ointment, mometasone furoate cream and the like.
2. Phototherapy and photochemotherapy
(1) Phototherapy with narrow-wave ultraviolet (NB-UVB) has certain effect on treating limited or generalized vitiligo.
(2) Photochemotherapy (PUVA) is a better treatment option for local externally-applied furocoumarins (8-MOP, psoralea tincture) and solarization of the limited vitiligo, and can be used for adults and children over 5 years old.
3. Transplantation therapy
It is suitable for patients with stable stage, few skin lesions for several days, and no scar. Common methods include autologous epidermal transplantation, microdermabrasion, autologous cultured melanocyte transplantation, etc.
4. Immunosuppressant
The externally applied calcineurin inhibitor (tacrolimus, pimecrolimus) has certain effect on the parts which are not suitable for using hormone or in order to avoid adverse reaction caused by long-term application of hormone.
5. Vitamin D3 derivatives
The vitamin D3 derivative can be used in combination therapy with NB-UVB, PUVA, etc. Can also be used in combination with topical hormone and calcineurin inhibitor.
