Abstract:
Objective To investigate the relationship between serum uric acid (SUA) levels and insulin secretion and insulin re-sistance in subjects with different glucose loads .Methods Totally 389 patients met the requirements ,and the subjects underwent o-ral glucose tolerance test (OGTT) to measure fasting SUA ,OGTT 0 ,30 ,60 ,120 min glucose (GLU) and insulin (INS) .According to the results of OGTT ,the subjects were divided into normal glucose tolerance group (NGT group ,n= 88) ,pre diabetes group (preDM group ,n=109) and diabetes mellitus (DM group ,n= 182) ,the insulin secretion index (IGI) ,120 min insulin secretion (AUC INS120/AUC GLU120 ) ,insulin resistance index (HOMA-IR) and Matsuda index were calculated .Calculated the quartile of SUA to divide the subjects to four groups ,the levels of insulin secretion and insulin resistance were compared between different glu-cose loading groups at different levels of SUA .The linear regression equation between SUA and insulin secretion and HOMA-IR was calculated .Results The SUA in DM group was lower than that of PreDM group [(346 .66 ± 90 .60)mmol/L vs .(367 .36 ± 92 .34)mmol/L] ,but slightly higher than that of NGT group[(339 .34 ± 89 .51)mmol/L] ,the difference was statistically significant (P<0 .01) .The IGI index and AUC INS120/AUC GLU120 index of DM group decreased with the increase of SUA (P<0 .01) ,and the Matsuda index decreased with the increase of SUA level (P<0 .05) .The linear equation of SUA and the IGI ,AUC INS120/AUC GLU120 ,HOMA-IR ,Matsuda index was Y=4 .050+0 .144X ,Y=2 .343+0 .206X ,Y =1 .288+0 .176X ,Y=129 .373-0 .202X re-spectively .Conclusion SUA was significantly associated with insulin secretion and insulin sensitivity .Insulin secretion in group DM increased with increasing SUA levels ,and insulin sensitivity decreased with increasing SUA levels .The linear equation of SUA and insulin secretion ,insulin sensitivity may be used to assess insulin function .
