Association between components of metabolic syndrome with chronic kidney disease in Benin City, Nigeria

Background: The metabolic syndrome (MetS) is a constellation of risk factors of metabolic origin that promote the development of cardiovascular disease. More recently, an association with chronic kidney disease (CKD) is being reported. However, most of these studies are non-indigenous. The aim of the study was to determine the association between components of MetS and CKD in a Nigerian population.Methods: Patients with MetS were recruited from a tertiary hospital in Benin City, Nigeria. Blood pressures and body mass indices were measured. Plasma glucose, serum lipids, urea and creatinine and spot urine albumin: creatinine ratio were analyzed. CKD was defined as estimated glomerular filtration rate <60mls/min+ urinary ACR >30mg/g creatinine.Results: Obesity, waist/hip ratio, diastolic blood pressure, total cholesterol and LDL-cholesterol were associated with CKD in univariate analysis. Body mass index and diastolic blood pressure were independent predictors of CKD. There was a relationship between the number of MetS traits and CKD.Conclusions: CKD in patients with MetS may therefore result from a synergistic effect of components of the syndrome. Diastolic blood pressure and obesity may predict CKD in MetS patients. Early detection and treatment of obesity and hypertension may thus be a strategy to target the increasing prevalence of renal disease in MetS
