Oxidative stress is a common occurrence in red blood cell (RBC) storage in blood banks throughout the world. Typically RBC units stored under routine standard protocol (stored in SAGM-CPD additive solution) can only be kept up to forty-two days for transfusion usage before being discarded. I am studying the effects of Ascorbic Acid (AA), N-acetylcysteine amide (AD4), and Serotonin or 5-hydroxytryptamine (5- HT) as additives in blood bank storage to find out if these additives can reduce storageinduced oxidative stress on red blood cells (RBCs), as well as to understand how potential blood storage additives can affect the shelf life of blood and post-transfusion recovery in patients. I conducted a literature review by studying various journal articles that examined metabolism to proteomics and the synergy of the different additives. These various additives significantly alleviated a range of signs of oxidative stress on RBCs including but not limited to replenishing glutathione (GSH), decreasing percent hemolysis, inhibiting the phospholipid rearrangement, and encouraging ATP production. By reducing these symptoms of oxidative stress, RBCs are able to last longer without any significant changes biochemically, and decrease the chances of post-transfusion complications such as Graft vs Host Disease (GVHD). The new additive solution could potentially increase the patient’s post-transfusion recovery rates as well as increase the shelf life of RBC storage units past the standard forty-two days.
