Background technique

Blood product safety includes transfusion-associated graft-versus-host diseases caused by blood-borne pathogens (viruses, bacteria, protozoa, spirochetes, etc.), blood cells (such as lymphocytes). Common methods for virus inactivation in plasma include pasteurization, S/D, membrane filtration, methylene blue and riboflavin photochemistry. Among them, methylene blue is widely used in China, but There are some deficiencies in this method, including the residual toxicity of methylene blue, the loss of plasma protein after treatment, and the cumbersome operation; the method of preventing transfusion-related graft-versus-host disease is to irradiate blood (inactivate lymphocytes).

The riboflavin photochemical inactivation of the virus is considered to be a promising method. The principle is that riboflavin can be embedded in the nucleic acid of the virus due to its structural properties, and its electron transfer is stimulated under ultraviolet irradiation to oxidize the guanine on the nucleic acid. Residues, the nucleic acid of the virus is modified and damaged, can no longer be copied and repaired, so as to achieve the effect of inactivating the virus, and riboflavin is a safe drug, no toxic side effects, no need to be filtered after adding treatment. Among the existing approved products, only riboflavin photochemical method is used for virus inactivation of platelets, and a single device can only process up to two treatment units at a time.
