Abstract

Diabetes is a leading cause of chronic kidney disease (CKD) in the developed world. Promoters of the progression of kidney disease include the traditional profile of cardiovascular risk factors. However, the development of CKD and vulnerability to end-stage renal disease (ESRD) is highly variable. Determinants of the susceptibility to ESRD may include non-traditional risk factors such as gene-environment interactions, socio-geographic factors and/or treatment strategies. We review the conflicting clinical relevance of studies implicating pathways related to oxidative stress. These pathways are strongly implicated in the phenotype of some groups of high-risk patients and could assume importance in clinical care. Recent clinical trial evidence has shown that newer glucose-lowering agents also have beneficial effects on reducing the incidence of renal dysfunction and cardiovascular events in high-risk patients. Research is required to identify which patients will benefit most from newer approaches to managing diabetes. Understanding the relationship of non-traditional risk factors to renal and cardiovascular disease could help clinicians targeting new therapeutic approaches in the management of type 2 diabetes.
