ABSTRACT

Objective To observe the effect of saxagliptin combined insulin four times to strengthen the vola-tility on blood glucose variability in patients with type 1 diabetes.Methods According to random number table meth-od,60 patients with type 1 diabetes were divided into DPP4 group(28 cases)and the control group(32 cases).The control group was given insulin four times to strengthen the volatility(insulin aspart/insulin lispro +insulin glargine /insulin detemir),the DPP4 group on the basis of insulin four times to strengthen the volatility plus the saxagliptin 5mg/d,all patients into the group after1 -3D and 13 -15D using CGMS(Medtronic)continuously monitor the blood glucose.Results (1)Within the group comparisonthe DPP4 group1 -3d after treatmentMAGE and SDBG,MBG, LAGE,PT10.0,PT3.9 were lower than before treatment,including MAGE [(6.91 ±1.63)mmol/L vs.(6.31 ± 1.42)mmol/L,t =0.993],SDBG[(2.63 ±0.81)mmol/L vs.(2.41 ±0.51)mmol/L,t =0.751],MBG[(11.51 ± 1.24)mmol/L vs.(10.87 ±2.01)mmol/L,t =1.077],LAGE[(9.43 ±1.73)mmol/L vs.(8.56 ±1.97)mmol/L, t =1.125],PT10.0[(12.99 ±5.61)% vs.(9.66 ±5.03)%,t =1.427],PT3.9[(5.51 ±2.43)% vs.(5.07 ± 2.44)%,t =1.141],there were statistically significant differences compared with before treatment(all P 0.05);13 -15d after treatmentMAGE[(6.88 ±1.49)mmol/L vs.(2.97 ±0.86)mmol/L,t =3.021],SDBG[(2.77 ±0.73)mmol/L vs.(1.12 ±0.43)mmol/L,t =1.964],MBG [(11.67 ±1.46)mmol/L vs.(7.44 ±0.93)mmol/L,t =2.760],LAGE[(9.55 ±1.77)mmol/L vs.(6.53 ±1.21)mmol/L, t =2.409],PT10.0[(13.58 ±5.14)% vs.(4.72 ±2.37)%,t =2.657],PT3.9[(5.36 ±2.05)% vs.(3.05 ± 2.60)%,t =1.840]were decreased,there were statistically significant differences compared with before treatment (P 0.05 );13 -15d after treatmentMAGE [(6.91 ±1.63 )mmol/L vs.(6.07 ± 1.36)mmol/L,t =1.223],SDBG[(2.63 ±0.81)mmol/L vs.(1.91 ±0.93)mmol/L,t =0.984],MBG[(11.51 ± 1.24)mmol/L vs.(8.82 ±1.13)mmol/L,t =1.808],LAGE[(9.43 ±1.73)mmol/L vs.(7.06 ±1.57)mmol/L, t =1.963],PT10.0[(12.99 ±5.61)% vs.(6.74 ±3.35)%,t =2.012],PT3.9[(5.51 ±2.43)% vs.(4.73 ± 2.57)%,t =1.541]were decreased,there were statistically significant differences in MBG,LAGE,PT10.0 compared with before treatment(all P <0.05).Group comparision1 -3d after treatmentthe DPP4 groupMAGE[(4.81 ± 1.15)mmol/L vs.(6.31 ±1.42)mmol/L,t =2.351],SDBG[(2.14 ±0.69)mmol/L vs.(2.41 ±0.51)mmol/L, t =1.332],MBG[(9.76 ±1.58)mmol/L vs.(10.87 ±2.01)mmol/L,t =0.856],LAGE[(7.74 ±1.88)mmol/L vs.(8.56 ±1.97)mmol/L,t =2.102],PT10.0 [(7.47 ±4.96)% vs.(9.66 ±5.03)%,t =2.667],PT3.9 [(4.64 ±2.14)% vs.(5.07 ±2.44)%,t =1.890]were all significantly lower than the control group,there were statistically significant differences in MAGE,LAGE,PT10.0 between the two groups(all P <0.05).13 -15d after treatmentthe above indictors,the DPP 4 group was decreased obviously compared with the control group,MAGE [(2.97 ±0.86)mmol/L vs.(6.07 ±1.36)mmol/L,t =2.854],SDBG[(1.12 ±0.43)mmol/L vs.(1.91 ± 0.93)mmol/L,t =2.328],MBG[(7.44 ±0.93)mmol/L vs.(8.82 ±1.13)mmol/L,t =2.125],LAGE[(6.53 ± 1.21)mmol/L vs.(7.06 ±1.57)mmol/L,t =2.111],PT10.0[(4.72 ±2.37)% vs.(6.74 ±3.35)%,t =2.312] and PT3.9 [(3.05 ±2.60)% vs.(4.73 ±2.57)%,t =2.237],there were statistically significant differences between the two groups (P <0.05 or P <0.01).Conclusion The combination of DPP4 inhibitors and insulin four renforcement can improve blood glucose fluctuation in patients with type 1 diabetes,reduce the dosage of insulin and not increase incidence of hypoglycemic events.
