RESUMO
Objective:To investigate the association of serum cholinesterase(ChE) with insulin resistance(IR) in patients with type 2 diabetes mellitus(T2DM).Methods:General information and laboratory results of 376 hospitalized patients with type 2 diabetes were collected from the Endocrinology Department of Xuzhou Medical University Affiliated Hospital from June 2020 to November 2022. Based on quartile levels of serum cholinesterase(ChE), the patients were divided into four groups: Q1 group(≤7 912 IU/L), Q2 group(7 913-9 083 IU/L), Q3 group(9 084-10 304 IU/L), and Q4 group(≥10 305 IU/L). The Homeostasis model was used to evaluate insulin resistance(HOMA-IR) for each group, and the correlation between ChE and HOMA-IR was analyzed. Results:As ChE levels increased, HOMA-IR levels significantly increased( P<0.05). Spearman correlation analysis showed that ChE was positively correlated with body mass index, diastolic blood pressure, high-sensitivity C-reactive protein, HbA 1C, total cholesterol, triglycerides, low density lipoprotein-cholesterol(LDL-C), aspartate aminotransferase, alanine aminotransferase(ALT), glutamyl transpeptidase, prealbumin, albumin, uric acid, and HOMA-IR( P<0.05). ChE was negatively correlated with age, duration of diabetes, and blood urea nitrogen( P<0.05). Multivariat stepwise linear regression analysis showed that disease duration, body mass index, HbA 1C, ALT, and ChE were independent influencing factors of HOMA-IR( P<0.01). Logistic regression analysis showed that compared to the Q1 group, the risks of developing IR in the Q4, Q3, and Q2 groups were 3.969(1.791-8.797), 2.100(1.059-4.164), and 2.026(1.071-3.833), respectively. Conclusion:Serum ChE is closely associated with IR in patients with T2DM.
