The association between retinol binding protein 4 and peripheral neuropathy in type 2 diabetic patient

Background & Objective: The most common microvascular consequence of diabetes is peripheral neuropathy. A very common ailment that has a significant impact on a patient's quality of life is peripheral neuropathy (PN). The purpose of this study was to look into the possible link between retinol binding protein 4 (RBP4) and peripheral neuropathy in individuals with type 2 diabetes mellitus (T2D), as the relationship between RBP4 and PN is still unclear. Methodology: We enrolled 152 participants who were matched for age and sex in a case control study during August and December 2023. There were 50 healthy controls, 50 diabetic patients without PN, and 52 diabetic patients with PN. ELISA was used to measure serum RBP4. Results: Diabetic individuals with PN had significantly greater serum levels of RBP4 than diabetic patients without PN (P ˂ 0.001). Increased age (r = 0.262, P ˂ 0.01), DM duration (r = 0.565, P ˂ 0.01), and BMI (r = 0.183, P ˂ 0.05) were all substantially linked with RBP4 levels. RBP4 levels exhibited a negative correlation with high-density lipoproteins (HDL) and a positive correlation with total cholesterol, triglycerides, low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL). Conclusion: Elevated RBP4 level is strongly and independently linked with PN in type 2 diabetic patients, and may play an important role in PN progression.
