Abstract

Background: To explore serum inflammatory factors and 25-hydroxyvitamin D and diabetic vascular lesions in patients with T2DM.

Methods: A total of 362 adult (aged 18 years) patients with T2DM hospitalised from April 2022 to June 2024 were selected as research subjects. A patient's body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), age, sex, and length of illness were among the general data gathered. Blood parameters, glycated haemoglobin (HbA1c), fasting blood glucose (FPG), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), inflammatory factors [C-reactive protein (CRP), interleukin-6 (IL-6)], and 25-hydroxyvitamin D [25(OH) D] were determined. The homeostatic model assessment of insulin resistance index (HOMA-IR) and the systemic inflammatory index (SII) were computed. The vascular lesions were divided into three groups: the simple T2DM group (155 patients), the T2DM microvascular lesion group (122 patients), and the T2DM macrovascular lesion group (85 patients). One-way analysis of variance, the Kruskal-Wallis H test, or the c2 test was used for comparisons among multiple groups. The relationship between 25(OH) D and several inflammatory markers was examined using Spearman correlation analysis, and the factors influencing diabetic vascular lesions were analysed using multivariate logistic regression analysis.

Results: The levels of 25(OH) D in both the T2DM microvascular lesion group and the T2DM…
