Abstract: Objective The study was conducted to assess the prediction of non-alcoholic fatty liver diseases (NAFLD) in patients with type 2 diabetes mellitus (T2DM) by neutrophil-to-lymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) . Methods 110 patients with T2DM and 121 patients with T2DM and NAFLD were included in the Department of Endocrinology, Second Provincial People's Hospital between January 2021 and October 2022, and the NAFLD was proven by ultrasonography. The blood routine was checked-up. The risk factors of T2DM with NAFLD were assessed by multivariate Logistic analysis, and predictive efficacy was evaluated by ROC curve. Results The body mass index in patients with T2DM and concomitant NAFLD was (25.4±3.5)kg/m2, much greater than [(23.2±3.1)kg/m2, P<0.05], while the course of disease was 5.0(2.0, 8.0)yr, significantly shorter than [8.0(3.0, 13.0)yr, P<0.05] in patients with T2DM; serum alanine aminotransferase, aspartate aminotransferase, glutamyl transpeptidase, uric acid, triglyceride and total cholesterol levels in patients with T2DM and NAFLD were all significantly greater than in patients with T2DM, while serum high density lipoprotein cholesterol level was much lower than in patients with T2DM (P<0.05); the blood lymphocyte count in patients with T2DM and NAFLD was (1.7±0.4)×109/L, much lower than [(2.2±0.6)×109/L, P<0.05], while the NLR and PLR were (2.4(1.8, 3.2)) and (126.1(93.3, 157.8)), both significantly greater than [1.5(1.2, 2.3) and 89.6(66.9, 116.5), respectively, P<0.05] in patients with T2DM; the Logistic analysis showed that the BMI, NLR and PLR were the risk factors for coincidence of NAFLD in patients with T2DM (P<0.05); the ROC analysis demonstrated that the sensitivities and the specificities by NLR and PLR in prediction of NAFLD in patients with T2DM were 64.5% and 75.0%, and 71.9% and 65.4%, respectively. Conclusion The surveillance of NLR and PLR, easily accessible, in patients with T2DM might help screen preliminarily NAFLD, and warrants further clinical investigation.
