Patients were subjected to blood and urine investigations. DNA extraction and Restriction fragment Length Polymorphism (RFLP) was done in Department of Biochemistry. Controls were unrelated healthy attendants with no history of Diabetes Mellitus, HTN, Chronic Kidney Disease (CKD). <strong>Results:</strong> Mean Systolic BP, Fasting Blood Glucose, Post Prandial Blood Glucose, HBA1c, Total Cholesterol were significantly higher in diabetes mellitus and diabetic nephropathy groups than control group. Estimated Glomerular Filtration Rate was significantly lower in diabetic nephropathy (p value < 0.001). UMCP1, Urinary Albumin Creatinine Ratio, TNF alfa were higher in diabetes mellitus and nephropathy with p value (<0.001, 0.006 < 0.001) respectively. In between DM and Diabetic Nephropathy groups nfkb1 gene expression, umcp1 and tnf alfa levels were significantly increased in Diabetic nephropathy with p value 0.019, <0.01, 0.001 respectively. Insertion/insertion NFkB1 gene polymorphisms were more in diabetic nephropathy group and were positively correlated with inflammatory markers UMCP1 (r = 0.517, p < 0.01) and TNF alfa (r = 0.172, p = 0.19). <strong>Conclusion:</strong> insertion/insertion NFkB1 gene polymorphism increases the risk of nephropathy by 2.52 times (OR = 2.52, 95% CI: 0.04 - 0.63, p value = 0.019) in diabetes patients in eastern India. 展开更多
