Treatment for Graft-Versus-Host Disease includes Photopheresis.
Photopheresis is a highly specialized medical process that extracts and separates patients' white blood cells from the blood and exposes them to ultraviolet light and a photoactive drug. This process modifies the function of the white blood cells to potentially control or eliminate the cells contributing to the disease. The modified white blood cells are returned to patients to potentially stimulate a positive therapeutic response.
Photopheresis is a treatment in which white blood cells are collected, then treated with a medication that is activated by ultraviolet light, acting as a "vaccination" against disease-producing T-cells.
