The Role of Oxidative Stress and Systemic Inflammation in Kidney Disease and Its Associated Cardiovascular Risk
Chronic kidney disease (CKD) is a major global health burden, with a prevalence of 10–15% and high mortality rates. In particular, CKD portends a disproportionately high risk of cardiovascular disease beyond the traditional cardiovascular risk factors, with pathophysiological factors such as oxidative stress, inflammation and hyperuricaemia considered to exert an additional role in accelerated atherosclerosis. The presence of heightened oxidative stress and systemic inflammation in CKD is associated with increased mortality. The possible underlying mechanisms include gut dysbiosis, dialysis factors, infections, metabolic acidosis and hyperuricaemia. The state of oxidative stress and systemic inflammation are closely linked and perpetuate each other resulting in progression of CKD and cardiovascular disease. Potential interventions to alleviate the oxidative stress and inflammation in CKD include lifestyle modifications including dietary changes and exercise, optimization of dialysis procedure and pharmacotherapeutic agents including antioxidants. They present a potentially highly effective approach to add to the currently available traditional risk-modification strategies. To date, the majority of the published trials have had a small number of participants with a short duration of follow up. Therefore, no robust evidence has been established. Larger trials with meaningful clinical outcomes and longer follow up are required to evaluate such potential therapies.
