Urinary albumin excretion is independently associated with C-reactive protein levels in overweight and obese nondiabetic premenopausal women.
Department of Emergency and Transplant, University of Bari, Italy.
OBJECTIVES: C-reactive protein (CRP) and microalbuminuria are nowadays considered markers of chronic inflammation of the arterial wall and of endothelial dysfunction, respectively. An increase of CRP levels and of urinary albumin excretion (UAE) rate have both been reported to be independently associated with a higher risk of cardiovascular morbidity and mortality in the general population. The aim of the present study was to evaluate the possible correlation between UAE and CRP concentrations in overweight and obese premenopausal women. DESIGN AND SETTING: A cross-sectional study in a primary care setting. SUBJECTS, MAIN OUTCOME MEASURES: CRP levels and UAE rate were measured in 103 overweight and obese premenopausal women, aged 18-45 years. Other measurements included: central fat accumulation, as evaluated by waist circumference, insulin resistance, as calculated by homeostatic model assessment (HOMAIR); fat-free mass (FFM), as measured by bioimpedance analysis; blood pressure; and fasting plasma levels of glucose, insulin, and lipids. RESULTS: Urinary albumin excretion was positively correlated with body mass index (BMI) (P < 0.01), waist circumference (P < 0.001), diastolic blood pressure (P < 0.01), triglycerides (P < 0.01), HOMAIR (P < 0.05), and CRP levels (P < 0.05); and negatively associated with HDL cholesterol (P < 0.001). After multivariate analysis, diastolic blood pressure, HDL cholesterol, and CRP levels maintained their significant correlation with UAE. CONCLUSION: Our study shows a strong relationship between UAE and CRP concentrations, irrespective of age and other anthropometric and metabolic variables. On this basis, it can be argued that inflammation of the arterial wall, as indicated by higher CRP plasma levels, and endothelial dysfunction, as shown by higher UAE rate, might represent simultaneous phenomena in the development of atherosclerosis in overweight and obese premenopausal women.
