Molecular Insights and Novel Approaches toward Individualized Arteriovenous Fistula Care

The aim of the paper is to summarize the current understanding of the molecular biology of arteriovenous fistula (AVF). It intends to encourage vascular access teams, care providers, and scientists, to explore new molecular tools for assessing the suitability of patients for AVF as vascular access for maintenance hemodialysis (HD). This review also highlights most recent discoveries and may serve as a guide to explore biomarkers and technologies for the assessment of kidney disease patients choosing to start kidney replacement therapy. Objective criteria for AVF eligibility are lacking partly because the underlying physiology of AVF maturation is poorly understood. Several molecular processes during a life cycle of an AVF, even before creation, can be characterized by measuring molecular fingerprints using newest “omics” technologies. In addition to hypothesis-driven strategies, untargeted approaches have the potential to reveal the interplay of hundreds of metabolites, transcripts, proteins, and genes underlying cardiovascular adaptation and vascular access-related adjustments at any given timepoint of a patient with kidney disease. As a result, regular monitoring of modifiable, molecular risk factors together with clinical assessment could help to reduce AVF failure rates, increase patency, and improve long-term outcomes. For the future, identification of vulnerable patients based on the assessme nt of biological markers of AVF maturation at different stages of the life...
