title: Metabolic syndrome and chronic kidney disease.
abstract: Obesity is a global health threat because of its associated metabolic and cardiovascular complications. Metabolic and hemodynamic complications of obesity (insulin resistance and hyperglycemia, hypertension, atherogenic dyslipidemia) are often clustered in the metabolic syndrome, leading to high cardiovascular morbidity and mortality. In recent years, epidemiological studies have clearly indicated that both obesity and the metabolic syndrome are independent risk factors for chronic kidney disease and these associations are at least in part independent of diabetes and hypertension per se. Additional mechanisms associated with obesity and metabolic syndrome leading to reduced renal function may include altered levels of adipose tissue hormones, inflammation, and oxidative stress. The ongoing worldwide obesity epidemic is therefore likely to increase the number of patients with chronic uremia and features of the metabolic syndrome in the next few years. Moreover, the onset and maintenance of renal damage may worsen metabolic syndrome features including insulin resistance and hypertension, leading to potential vicious cycles with negative clinical effect. Further understanding of the interactions between obesity, metabolic syndrome, and chronic kidney disease represents a potential strategy to design more effective treatments aimed at reducing morbidity and mortality in uremic patients.
