Abstract:Objective To explore the relationship between neutrophil to lymphocyte ratio (NLR) and type 2 diabetic nephropathy. Methods In this case-control study, the clinical data of 306 adult patients with type 2 diabetic nephropathy in our hospital from January 2010 to December 2015 were retrospectively analyzed. Then, the correlations of type 2 diabetic nephropathy with NLR, age, sex, duration of the disease, BMI, WBC count, neutrophil count, lymphocyte count, serum creatinine, blood urea nitrogen, serum uric acid, fasting blood glucose, glycosylated hemoglobin, total cholesterol, triglyceride, low -density lipoprotein and high -density lipoprotein were analyzed. Results Person correlation analysis showed that NLR was positively related with microalbuminuria (r = 0.868,p =0.012). Logistic regression analysis showed that NLR was a risk factor of type 2 diabetic nephropathy [OR = 2.955(95% CI: 1.445, 3.854),p = 0.022]. Conclusions High NLR is closely related to type 2 diabetic nephropathy. Clinical doctors should pay attention to type 2 diabetic patients with a high NLR.
