Abstract

Background: Chronic inflammation in type 2 diabetes mellitus (T2DM) is an essential contributor to the development of diabetic retinopathy (DR). The monocyte–to–high-density lipoprotein cholesterol (HDL-C) ratio (MHR) is a novel and simple measure related to inflammatory and oxidative stress status. However, little is known regarding the role of the MHR in evaluating the development of DR.Methods: A total of 771 patients with T2DM and 607 healthy controls were enrolled in this cross-sectional study. MHR determination and eye examination were performed. The association of MHR with the prevalence of DR in T2DM patients was analyzed.Results: The MHR in patients with DR was significantly higher than that in both non-DR diabetic patients (P < 0.05) and healthy controls (P < 0.01). No significance was observed in the MHR of different DR severity grades. Moreover, the MHR was similar between patients with non-macular oedema and those with macular oedema. Logistic regression analysis demonstrated that MHR was independently associated with the prevalence of DR in diabetic patients [odds ratio (OR) = 1.438, 95% confidence interval (CI): 1.249–1.655, P < 0.01]. After additional stratification by HbA1c level and diabetic duration, the MHR was still independently associated with the prevalence of DR.Conclusions: Our study suggests that the MHR can be used as a marker to indicate the prevalence of DR in patients with T2DM.

Highlights

Type 2 diabetes mellitus (T2DM) is a highly and rapidly evolving global health issue [1, 2], even in patients with prediabetes, the risk of macrovascular and microvascular disease were increased [3,4,5]
The monocyte count–to–high-density lipoprotein cholesterol (HDL-C) ratio (MHR) can reflect the inflammatory status and is related to the development of disease associated with chronic inflammation
Laboratory assessments consisted of fasting blood glucose, liver and renal function, uric acid, total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), which were examined by a HITACHI (Tokyo, Japan) 7180 Automatic Analyser using 8-h overnight fasting blood samples

Summary

Introduction

Type 2 diabetes mellitus (T2DM) is a highly and rapidly evolving global health issue [1, 2], even in patients with prediabetes, the risk of macrovascular and microvascular disease were increased [3,4,5]. Plasma high-density lipoprotein cholesterol (HDL-C) has an inverse relationship with DR risk [10, 11]. The monocyte count–to–HDL-C ratio (MHR) can reflect the inflammatory status and is related to the development of disease associated with chronic inflammation. Chronic inflammation in type 2 diabetes mellitus (T2DM) is an essential contributor to the development of diabetic retinopathy (DR). The monocyte–to–high-density lipoprotein cholesterol (HDL-C) ratio (MHR) is a novel and simple measure related to inflammatory and oxidative stress status. Little is known regarding the role of the MHR in evaluating the development of DR
