Abstract:
Objective To investigate the interaction between serum uric acid(SUA)and islet β cell function,and its influence in the development of diabetic peripheral neuropathy(DPN)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 122 patients with T2DM who visited General Medicine Department of our hospital from January 2019 to May 2023 were enrolled in this study and divided into two groups according to whether they had DPN:T2DM group(n=30)and DPN group(n=92).Patients in DPN group were further divided into three groups according to the severity of DPN:mild DPN group(L-DPN,n=30),moderate DPN group(M-DPN,n=36)and severe DPN group(H-DPN,n=26).The clinical data and biochemical indexes were compared and analyzed among the four groups.Logistic multivariate analysis was used to analyze the relationship between SUA and islet β cell secretory function and severe DPN.Multivariate logistic regression was used to analyze the risk factors for the severity of DPN.Stepwise regression method was used to screen the most important related factors for the severity of DPN,and a nomogram model was constructed and validated.The interaction between SUA and islet β cell function,and its influence in the development of DPN in T2DM patients were analyzed.Results Multivariate logistic regression analysis showed that age,SUA,aspartate aminotransferase,HDL-C,HbAlc,islet β cell secretion function(C2/C0)and insulin resistance index(HOMA-IR)were all independent influencing factors for the severity of DPN(P<0.05).The C indices of SUA,C2/C0,HOMA-IR,HbAlc and HDL-C prediction models were 0.776 and 0.769 on the training set and validation set respectively,which were most correlated with the aggravation of DPN degree.The area under the curve of the nomogram model for predicting the risk of DPN severity was 0.928(95%CI 0.856～0.986)and 0.917(95%CI 0.856～0.986)before and after validation respectively.The mean absolute error of the calibration curve was 0.013,which could be used as a risk tool to predict the risk of DPN aggravation.The results of interaction analysis showed that there were multiplicative and additive interactions between SUA and islet β cell secretion.Conclusions There is an interaction between SUA and islet β cell secretion function,which is a risk factor for the aggravation of DPN.The risk factors can be early warned according to the nomogram model,so as to carry out targeted prevention and treatment for T2DM patients.
