Abstract:
Objective:To investigate the association of 24 h urinary glucose between blood glucose fluctuation and islet function.Methods:A cross-sectional survey of 124 inpatients with type 2 diabetes was conducted,the clinical data were collected,dynamic blood glucose monitoring system(CGMS)was applied to assess blood glucose fluctuation,the pancreatic β cell secretion function was calculated,aiming to investigate the association of 24 h urinary glucose between blood glucose fluctuation and islet function.Objective:The average of the renal threshold for glucose(RTG)was 11.8 mmol/L and of which 75%were elevated(>10 mmol/L).24 h urinary glucose was 30.54 g.Correlation analysis demonstrated that 24 h urinary glucose was positively associated with fasting blood glucose(FBG),2 h postprandial blood glucose(2 h PBG),the mean blood glucose(MBG),fasting plasma(preprandial)glucose area under the curve(AUC2),postprandial glucose area under the curve(AUC1)and glomerular filtration rate(eGFR),there was a significantly negative relationship between 24 h urinary glucose and the mean amplitude of glucose excursions(MAGE)and RTG,but not associated with course of disease,gender,age of patient,body mass index(BMI),blood pressure、absolute means of daily differences(MODD),the pancreatic β cell secretion function and HbA1c.Multiple stepwise regression analysis showed that 24 h urine sugar was correlated with MAGE,MBG,FBG,eGFR,RTG and AUC2(absolute value of β' was-0.668,0.437,0.148,0.116,-0.107,and 0.086,respectively;P<0.05).Conclusions:The average of the renal threshold for glucose in patients with type 2 diabetes was elevated.The 24 h urinary glucose was related to blood glucose level,blood glucose fluctuations assessed by CGMS,eGFR and RTG,among which,MAGE influenced 24 h urinary glucose most.MAGE may be the most predictive risk factor for 24 h urinary glucose.
