Abstract:
Objective To explore the correlation between serum glycosylated hemoglobin(HbA1c),lym-phocyte activation gene-3(LAG-3)and thyroid nodules in patients with type 2 diabetes mellitus(T2DM).Methods A total of 120 T2DM patients with thyroid nodules admitted to the Third Hospital of Hebei Medi-cal University from July 2021 to July 2022 were included as the study group,and 100 simple T2DM patients(without thyroid nodules)were included as the control group during the same period.According to the patho-logical examination results of thyroid nodules,the study group was grouped into a benign nodule group(85 ca-ses)and a malignant nodule group(35 cases).Enzyme linked immunosorbent assay was applied to detect the serum LAG-3 level of all study subjects.Fully automated glycated hemoglobin analyzer was applied to detect HbA1c level in all study subjects.Spearman method was applied to analyze the correlation between serum HbA1c,LAG-3,and thyroid imaging report and data system(TI-RADS)scores in patients with T2DM and thyroid nodules.Multivariate Logistic regression was applied to analyze the influencing factors of T2DM with thyroid nodules.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of HbA1c and LAG-3 levels in T2DM with thyroid nodules.Results Compared with the control group,the level of HbA1c in the study group was obviously higher(P<0.05),while the level of LAG-3 was obviously lower(P<0.05).Compared with the benign nodule group,the serum LAG-3 level in the malignant nodule group was obviously lower(P<0.05),while the level of LAG-3 was obviously lower(P<0.05).Spearman analysis showed a positive correlation between HbA1c level and TI-RADS score in T2DM patients with thyroid nod-ules(r=0.378,P<0.001),while the serum LAG-3 level was negatively correlated with TI-RADS score(r=-0.472,P<0.001).The results of multivariate Logistic regression analysis showed that HbA1c was a risk factor for the occurrence of thyroid nodules in T2DM patients(P<0.05),and LAG-3 was a protective factor for the occurrence of thyroid nodules in T2DM patients(P<0.05).The combination of HbA1c and LAG-3 in the diagnosis of T2DM with thyroid nodules was superior to their individual diagnosis(Zcombination-HbA1c=2.542,P=0.011;Zcombination-LAG-3=3.098,P=0.002).Conclusion Patients with T2DM combined with thyroid nodules have obviously lower serum LAG-3 level and higher HbA1c level,and the two are related to the malignancy of thyroid nodules.
