We aimed to explore whether SII is associated with DPN in Chinese population.Methods: A cross-sectional study was conducted among 1460 hospitalized patients with T2DM. SII was calculated as the platelet count × neutrophil count/lymphocyte count, and its possible association with DPN was investigated by correlation and multivariate logistic regression analysis, and subgroup analyses.Results: Patients with higher SII quartiles had higher vibration perception threshold and prevalence of DPN (all P 5 years, hypertension, dyslipidaemia, poor glycaemic control, and estimated glomerular filtration rate < 90 mL/min/1.73 m2 (P for trend < 0.01 or P for trend < 0.05). The receiver operating characteristic curve analysis revealed that the optimal cut-off point of SII for predicting DPN was 617.67 in patients with T2DM, with a sensitivity of 45.3% and a specificity of 73%.Conclusion: The present study showed that higher SII is independently associated with increased risk of DPN, and SII might serve as a new risk biomarker for DPN in Chinese population.Keywords: systemic immune-inflammation index, diabetic peripheral neuropathy, vibration perception threshold, type 2 diabetes mellitus, Chinese population
