Biopreservation: Extension of the ex vivo Life Span of Stored Human Erythrocytes by the Addition of Ascorbic Acid to Additive Solutions in Modern Blood Banking DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Jorge Andrés Fontes Graduate Program in Chemical and Biomolecular Engineering The Ohio State University 2014 Dissertation Committee: Andre Francis Palmer, Advisor Jeffery J. Chalmers David W. Wood Copyright by Jorge Andrés Fontes 2014 Abstract The main goal of the research discussed in this dissertation is to extend the life span of erythrocytes in hypothermic storage. This dissertation focuses on the modification of the composition of modern additive solutions by the addition of an antioxidant, ascorbic acid (AA), to extend both the absolute and effective shelf life of red blood cells (RBCs). The research focuses on the analysis of the biochemical and biophysical changes that occur during hypothermic storage of RBCs (i.e. storage lesion). It is focused on the protecting effect of the addition of AA against the slow oxidative damage incurred by reactive oxygen species (ROS) formed during hypothermic storage. This dissertation presents in vitro analyses of both human (Chapter 3) and canine (Chapter 4) erythrocytes stored in AA-supplemented additive solutions. The analyses described (Chapter 2) are quantifications of the functional status of stored RBCs during hypothermic storage. The methods described demonstrate that important in vitro results that could translate to increased shelf life, viability of RBCs after transfusion, and most importantly, safety for the recipient of stored RBCs. This cost effective chemical is used broadly and approved by the United States Food and Drug Administration (FDA). The incorporation of this small molecule antioxidant into modern additive solutions involves essentially no change in blood banking procedure or infrastructure. Alternative methodology for the extension of RBC shelf life include desiccation, cryopreservation, and rejuvenation where the extension of shelf life is iii associated with a high degree of manipulation, technical knowledge, increased losses, change in blood banking infrastructure, and economic cost. The knowledge gained from this work provides a push into the use of antioxidants as method of RBC biopreservation that has been seldom studied. Overall, this dissertation presents an additive solution modified with ascorbic acid with the potential of extending the life span of stored erythrocytes for use in transfusion medicine. iv Dedication Dedicated to my wife, Verónica Elizabeth Pereira, my parents, Jorge Enrique Fontes and Myriam Fontes, my brother, Adrián Gabriel Fontes and the rest of my extended family v Acknowledgments I would like to express my most sincere gratitude to my advisor, Professor Andre F.
