ABSTRACT: Background: Diabetic nephropathy is one of the major complications of diabetes. Nephropathy patients must be evaluated for dyslipidemia as it is an established risk factor for cardiovascular events. We compared the degree of dyslipidemia among type 2 diabetes mellitus (T2DM) subjects with or without nephropathy and analyzed the factors associated with nephropathy among them. Methods: In this retrospective study, T2DM patients with overt nephropathy were enrolled in the study group (n = 50); without nephropathy were enrolled in the control group (n = 50). Both groups were matched for age duration of diabetes. After taking informed consent anthropometrical clinical examinations were done. Biochemical investigations (Total cholesterol, TG, HDL, LDL, VLDL, sdLDL-C, S. urea, S. creatinine were done in SCB MCH, Biochemistry department. Urine microalbumin per gm of creatinine was done. TG/HDL-C ratio, a surrogate marker for small, dense, LDL particles (sdLDL), and estimated glomerular filtration rate (eGFR) were calculated using equations. Results were analyzed statistically using SPSS version 20. Results: Mean Total cholesterol, TG, LDL, sdLDL are significantly high in nephropathy patients with p values 0.026, 0.012, 0.014, 0.04 respectively. Estimated GFR has a significant positive correlation with TCHOL (r = −0.850, p = 0.01), TG (r = −0.14, p = 0.008), LDL (r = −0.62 p = 0.037). Estimated GFR has a significant negative correlation with S. urea (r = −0.587, p ≤ 0.01), S. creatinine (r = −0.59, p ≤ 0.01), UACR (r = −0.47, p ≤ 0.01). Dyslipidema sdLDL is significantly more in nephropathy group in comparison to diabetic group with p values 0.033, 0.045 respectively. Conclusion: Our study shows that dyslipidemia was highly prevalent among subjects with nephropathy. So cardiovascular risks can be averted by regular screening for dyslipidemia in diabetic nephropathy patients.
