A novel combination therapy, an arthritis medication and light, was used to successfully restore skin color in vitiligo patients, shows study conducted by a team of Yale dermatologists published in JAMA Dermatology.
The study, led by associate professor of dermatology Brett King, M.D and his colleagues reported two cases of patients with significant loss of skin color from vitiligo, a chronic autoimmune disease that destroys skin pigment, leaving white splotches where there had been color. For King's patients, standard treatments, such as steroid creams and light treatment, had failed to restore pigmentation. To address these difficult cases, the research team combined the medication, tofacitinib, with narrow band ultraviolet B light therapy. In recent experiments, King and Dr. John Harris, a dermatologist at University of Massachusetts-Worcester, had shown that tofacitinib keeps the immune system from attacking the skin cells that manufacture melanin pigment (color), and light stimulates pigment-making cells to restore color to the skin.
After a few months of the combination therapy, there was remarkable improvement, report the researchers: One patient saw near-total restoration of skin color on her face, neck, chest, forearms, and shins. The other patient experienced similar success.
