BACKGROUND: Accumulating evidence indicates that dyslipidaemia plays an important role in the progression of kidney disease in patients with diabetes. Hyperlipidaemia is a risk factor for microalbuminuria in patients with diabetes. Little information exists on the prevalence and control of dyslipidaemia among diabetic patients with microalbuminuria in China. The aims of this study were to investigate the prevalence and control of dyslipidaemia among diabetic patients with microalbuminuria in a Chinese hospital as well as factors affecting the disease. METHODS: A total of 1060 type 2 diabetic inpatients were assigned to the with-microalbuminuria group (n = 635) or the without-microalbuminuria group on the basis of urinary albumin-to-creatinine ratios (UACRs = 30-299 mg/g). Serum levels and the control of lipid profiles were assessed and classified according to the 2011 American Diabetes Association (ADA) guidelines, and low-density lipoprotein-cholesterol (LDL-C) was also assessed and classified according to Chinese intensified control criteria. Multiple regression analyses were performed to examine the factors affecting lipid variables. RESULTS: Among patients with microalbuminuria, a significantly lower prevalence was found (33.1% vs. 58.6%; 35.3% vs. 52.5%, all p < 0.001) at target levels [LDL-C < 2.60 mmol/L or high-density lipoprotein-cholesterol (HDL-C) > 1.0 mmol/L for men and >1.3 mmol/L for women]. According to the intensified LDL-C goal (<2.07 mmol/L), a lower prevalence was found in male patients (15.5% vs. 32.7%, p < 0.001). Fewer patients with microalbuminuria were adherent to the therapy prescribed for dyslipidaemia (28.8% vs. 43.3%, p < 0.001). Even among patients who were on lipid-lowering treatment, the majority of individuals remained uncontrolled for all three lipid fractions [LDL-C, HDL-C and triglyceride (TG)] (82.5% vs. 69.0%, p = 0.003). Lipid and lipoprotein parameters were associated with gender and age. CONCLUSION: In China, diabetic patients with microalbuminuria displayed typical dyslipidaemias and were not adequately controlled. Intensified LDL-C and overall lipid-lowering clinical goals are potential precautions taken against diabetic nephropathy.
