RESUMEN
Forty-eight men with normal glucose tolerance were divided into fatty liver disease ( NAFLD, n =23 ) and non-NAFLD (n =25 ) groups. The blood glucose excursion was evaluated by continuous glucose monitoring system. The results showed that the mean amplitude of glucose excursion[MAGE, (2. 17± 1.13 vs 1.45±0. 42 )mmol/L]and standard deviation of blood glucose[SDBG, (0. 88 ±0. 45 vs 0. 61 ±0. 21 ) mmol/L]were significantly higher in NAFLD group than in non-NAFLD group( both P＜0. 05 ). MAGE and SDBG were positively correlated with body mass index, waist circumference, and the increased value of plasma glucose 0. 5 h after glucose loading( △G30,all P＜0. 05 ). In multiple regression analysis, △G30, waist circumference, and age were significant independent predictors for MAGE( P＜0. 05 or P＜0. 01 ). △G30 and waist circumference were significant independent predictors for SDBG( P＜0. 05 or P＜0. 01 ).
RESUMEN
Objective To explore relationship between excursion of blood glucose levels and cognitive performance in diabetic patients over aged 60 years.Methods A total of 108 diabetic patients over aged 60 years were recruited in this study and they wore under continuous blood glucose monitoring system (CGMS) for three days to evaluate excursion of their mean blood glucose (MBG) level and its standard deviation (SD).All the participants accepted cognitive function tests during continuous blood glucose monitoring, including mini mental status examination (MMSE), Montreal cognitive assessment (MOCA) and clock drawing test (CDT).Relationship of the SD of blood glucose level and cognitive performance in the three cognitive tests was assessed.Data were analyzed with CGMS software version 3.0.Results The SD reversely correlated with scores of MMSE (r = - 0.324, P ＜ 0.01 ) and CDT ( r =-0.325, P = 0.001 ), but they did not significantly correlate with MOCA scores (r = -0.212, P =0.081 ).Statistically significant difference was observed between the SD and scores of all three cognitive tests adjusted for glycosylated hemoglobin Alc (HbAlc) level (r = -0.387, -0.046 and -0.292, P =0.029, ＜0.001 and ＜ 0.001, respectively).The SD reversely correlated with scores of MMSE, MOCA and CDT adjusted for MBG (r= -0.314, -0.466 and -0.345, P ＜0.01, respectively).Results of multivariate linear regression analysis showed that the SD reversely correlated to scores of MMSE, MOCA and CDT (β = - 0.378, - 0.224 and - 0.346, all P ＜ 0.05).Conclusions Excursion of blood glucose levels can influence their cognitive performance in diabetic patients over aged 60 years, leading to decrease in their overall cognitive function and activities as its excursion large enough.
RESUMEN
Objective To compare the excursion of blood glucose (BG) in the type 2 diabetes mellitus treated with oral antidiabetic drugs (OADs) plus glargine or human isophane insulin (HII). Methods A 1 : 1 randomization schedule assigned 30 type 2 diabetics inadequately controlled on OADs (fasting BG>9.0 mmol/L and HbA1C > 8.5%) to 2 groups additionally treated with glargine or HII. The insulin dose was titrated to achieve fasting capillary BG<6.0 mmol/L. Montoring BG with continuous glucose monitoring system, then the standard deviation of BG (SDBG), maximal excursion of BG (LAGE) and coefficient of variation (CV) of fasting plasma glucose (FPG) were calculated. Results SDBG (1.49±0.35 vs 1.73±0.46), LAGE (3.23±0.76 vs 3.73± 1.00) and CV-FPG (17.26±2.24 vs 20.33±3.21) were lower in glargine group than those in HII group (P< 0.05). No difference could be found in hypoglycaemia between two groups. Conclusion OADs plus glargine could make blood glucose more stable than OADs plus HII without increasing the incidence of hypoglycaemia.
RESUMEN
A total of 123 type 2 diabetics was randomised into 3 groups to receive gliclazide-MR, gliclazide or glibenclamide treatments for 16 weeks.All the subjects took self-monitoring of blood glucose (SMBG) during the trial.The effect of therapy was similar in 3 groups.The subtraction value between maximum and minimum blood glucose, mean postprandial maximum blood glucose, postprandial 2 h blood glucose, postprandial 2 h serum insulin and hypoglycaemia events were lower in gliclazide-MR group than those in glibenclamide group (all P＜0.01).The data suggest that SMBG is an useful method to evaluate blood glucose excursion.
RESUMEN
A total of 126 patients with type 2 diabetes mellitus were randomized into two groups:one received glimepiride 1 mg twice daily and the other 2 mg once daily.Fasing blood glucose(BG),BG 2 h after meals(breakfast,lunch and dinner)and HbA_(IC)were tested,△and standard deviation of the 4 point BG were calculated.It was found that two kinds of administration of glimepiride were equally effective in decreasing BG and once daily aministration could ease better the fluctuation of BG.
RESUMEN
The effects of human insulin 70/30 and insulin lispro 75/25 were compared in improving postprandial blood glucose excursions in 106 patients with type 1 or 2 diabetes in a one-month,open-labelled,self- controlled trial .The results showed that treatment of diabetic patients with insulin lispro 75/25 significantly improved 2 h postprandial blood glucose excursion compared to pre-study with human insulin 70/30 (baseline) without any significant adverse events or sustained hypoglycemic episodes.These physiological benefits were associated with a patient preference for insulin lispro 75/25.
