Characteristics of the Lipid Profile in Patients with Diabetes Mellitus and Chronic Kidney Disease

Abstract Background and aims Diabetes mellitus (DM) is one of the leading causes of end-stage chronic kidney disease (CKD). Patients with DM and CKD have a 10 or even 20 times higher cardiovascular risk (CVR) than the general population. Lipid metabolism disorders are more frequent in these patients, dyslipidemia being aggravated by the presence of hyperglycemia and insulin resistance. The main purpose of our study was to identify possible correlations between lipid profile parameters and altered renal function in patients with DM. We have also analyzed the correlations between lipid parameters, CKD, quality of glycemic control and CVR. Material and method: The study was performed on 2732 patients with DM which received medical treatment and care at the Center for Diabetes Timisoara, for a 6-month period from March to October 2016, 1508 women (55.2%) and 1224 men (44.8%), mean age 63.7 ± 9.1 (33-78) years and mean diabetes duration 12.4 ± 6.8 (6-33) years. The study group included 312 patients (11.4%) with T1DM and 2420 patients (88.6%) with T2DM. Results: The prevalence of CKD (GFR< 60 ml/min) was 12.5%. The levels of total cholesterol (TC), triglycerides (TG) and LDLc were significantly higher in the case of patients with DM and CKD (p<0.0001). Patients with CKD had twice the prevalence of ischemic heart disease and cerebrovascular disease when compared to patients without CKD. Peripheral artery disease was present in 16.9% of those with CKD and in 11% of those without CKD. Hypertension (HTN) was present in 91.8% of patients with CKD and in 67.1% of patients without CKD (GFR > 60 ml/min). Conclusion: Analyzed data showed a strong correlation between CKD, dyslipidemia and CVR in patients with DM. Impaired renal function was strongly correlated with age, duration of DM and weight status of these patients.
