Background and objectives: Diabetic nephropathy and retinopathy are microvascular complications of diabetes. Nephropathy is clinically manifested as an increase in urine albumin excretion. Total white blood cell count is a crude but sensitive indicator of inflammation and studied in many cardiac and non-cardiac diseases as an inflammatory marker such as acute myocardial infarction, stroke, and heart failure. In this study, the association of neutrophil to lymphocyte ratio (NLR) with diabetic nephropathy and retinopathy. Methods: This was a prospective observational study performed on patients with diabetic nephropathy +/- retinopathy. A total of v104 subjects diagnosed with 3type 2 diabetes mellitus registered in this study. NLR was calculated by analyzing differential leukocyte count in complete blood picture. Spot Albuminuria was tested by immune turbidimetry method. Urine creatinine was tested by jaffe’s kinetic method by which spot urine microalbumin to creatinine ratio is calculated. ANOVA, Independent t-test, chi-square test, Karl Pearson correlation were applied to find significance. P<0.05 was considered as statistically significant. Results: Totally 104 diabetic subjects were registered, 52 subjects had DN and 52 had normal urine albumin. Mean±SD NLR for a normal group is 2.5±1.1 and in DN group is 3.4±1.4 which was highly significant (P =0.001). Conclusion: Our study showed that there was a significant relation between NLR and DN; and positive correlation between NLR and urine microalbumin to creatinine ratio. Therefore, NLR may be considered as a novel surrogate marker of DN.
