Ischemia/reperfusion (I/R) injury plays a pivotal role in the development of graft dysfunction and allograft rejection after transplantation. Excessive free radical production and massive consumption of endogenous antioxidants are common mechanisms underlying I/R injury and are implicated in posttransplant organ damage and reduced graft viability. Ascorbic Acid (AA) is an essential micronutrient involved in several biological processes, from antioxidative response to the modulation of apoptosis and inflammation. These properties, combined to the safety profile, low cost, and ease of administration and measurement, make AA a potential bullet for reducing I/R damage in the setting of solid organ transplantation. Although multiple preclinical and clinical studies have been performed to investigate the effectiveness of AA administration in reducing I/R injury during transplantation, its therapeutic potential remains controversial as well as the optimal dosage, timing, and combination with other antioxidants. In this review, we summarize the AA modulated metabolic pathways, focusing on its potential role in the treatment of solid organ (kidney, liver, lung, heart, and pancreas) transplantation.

D001205 Ascorbic Acid A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.

D017209 Apoptosis A regulated cell death mechanism characterized by distinctive morphologic changes in the nucleus and cytoplasm, including the endonucleolytic cleavage of genomic DNA, at regularly spaced, internucleosomal sites, i.e., DNA FRAGMENTATION. It is genetically programmed and serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
