    Introduction: Cardiovascular disease is the main cause of death in Type 2 diabetic patient. Similarly diabetic nephropathy is the major risk factor for morbidity and mortality in diabetes mellitus patients. Cystatin C as a marker of renal function can facilitate the early prediction of cardiovascular risk along with the other classical markers in DM Type 2 patients. Cystatin C is identified as a promising marker of renal dysfunction and has emerged as a biomarker of cardiovascular risk. This study aimed to estimate and correlate the levels of plasma cystatin C with cardiovascular risk markers in type 2 diabetes mellitus patients. Methods: The study population included type 2 diabetes mellitus patients above 18 years of either sex. Among 129 diabetes mellitus type 2 patients, 125 patients were recruited and divided into group A with HbA1c ≤ 6.5% Hb and group B with HbA1c> 6.5% Hb. Fasting blood samples were analyzed for FBG, Total cholesterol, TRIG, HDL and Creatinine by enzymatic method. LDL by direct turbidimetric method. Plasma cystatin C and HbA1c were estimated by immunoturbidimetric method and hs-CRP by particle enhanced immunoturbidimetric method. Cardiovascular risk ratios TC/HDL, LDL/HDL and others were calculated. Results: About 73% of the patients recruited had poorly managed diabetes Patients with poor glycemic control (Group B, n = 91) had significantly higher values of hs-CRP (10.57 ± 4.58 mg/L), Total Cholesterol (4.56 ± 0.25 mmol/L), LDL (4.10 ± 0.25 mmol/L), TC/HDL (4.10 ± 1.39), LDL/HDL (2.56 ± 0.22) and Creatinine (68.52 ± 38.02). The study revealed a positive correlation between cystatin C and the endothelial inflammatory marker hs-CRP (r = 0.93, p = 0.001). Similarly HbA1c, LDL/HDL, Cholesterol and Triglycerides showed positive correlations with cystatin C of (r = 0.92, p = 0.022), (r = 0.81, p < 0.0001), (r = 0.80, p < 0.0001) and (r = 0.80, p = 0.022) respectively. Cystatin C also had a correlation with HDL (r = 0.71, p = 0.018). Creatinine and cystatin C also showed a positive correlation. (r = 0.48, p < 0.0001) Conclusion: Plasma cystatin C, a preclinical marker of renal dysfunction can be used as a predictive marker of diabetic dyslipidemia and cardiovascular risk in poorly controlled Type 2 Diabetes mellitus patients.
