How to treat children's vitiligo with narrow-spectrum medium-wave ultraviolet physiotherapy

Type:Uv phototherapy   Time:2018-09-03 21:39:55 Narrow-band UVB (NB-UVB) is a relatively new treatment for dermatological diseases. Narrow-spectrum UVB is a new type of treatment for chronic diseases such as psoriasis and vitiligo. By irradiating the skin lesions with ultraviolet rays of a certain wavelength, a photochemical reaction or an immune response is regulated, thereby achieving the purpose of treating certain intractable skin diseases. So, how is the effect of narrow-band UVB physiotherapy on children with vitiligo?

Some studies have used NB-UVB in 51 children with pan-type vitiligo. It was found that more than 75% of the skin lesions recovered in 53% of the children, 80% of the children did not expand the skin lesions, and the quality of life index of the children was significantly improved. The side effects were very mild. . Schemchun et al. selected 11 patients with vitiligo, including confined, segmental, and generalized patients. Results of 7 patients completed a 1-year trial, 5 of which had more than 75% of lesion recovery, and 2 had 50% of skin lesions. After recovery, the remaining 4 patients failed to complete the trial due to time. The results also fully affirmed the efficacy of NB-UVB on vitiligo. After oral administration of 8-methoxy psoralen and UVA and NB-UVB, it was found that NB-UVB is more prone to erythema and hyperpigmentation, suggesting the efficacy of NB-UVB combined with 8-methoxypsoralen on vitiligo. worthy of study.

Kanwar et al performed NB-UVB therapy in 20 patients, and 15 patients achieved complete color recovery 1 year after treatment.

With the rapid development of medical optical technology, clinical narrow-wavelength ultraviolet (NB-UVB) local irradiation treatment of vitiligo has been widely used, gradually replacing psoralen photochemotherapy (PUVA), which has been proved by experiments and clinical practice. The treatment of vitiligo is more safe, especially in the treatment of pregnant women and children, the effect is good, the adverse reactions are small, the operation is simple and easy, and the economic burden is small.
