目的 观察沙格列汀联合持续皮下输注胰岛素对胰岛β细胞功能较差的T2DM患者血糖波动的影响. 方法 选取胰岛功能较差的T2DM患者30例,采用持续皮下输注胰岛素治疗15d,第10天后不再调整胰岛素剂量,第13天晨起开始口服沙格列汀,第11~15天采用动态血糖监测系统(CGMS)监测血糖,比较第11~12天和第14~15天平均血糖波动幅度(MAGE)、血糖水平标准差(SD-BG)、最大血糖波动幅度(LAGE)、平均血糖水平(MBG)、血糖>10.0 mmol/L的时间百分率(PT10.0)、血糖<3.9 mmol/L时间百分率(PT3.9)的变化. 结果 与口服沙格列汀前相比,口服沙格列汀后MAGE [(5.28±1.44)vs(3.27±0.76)mmol/L,P<0.01]、SDBG[(2.43±0.50)vs(1.79±0.45) mmol/L,P<0.01]、MBG[(8.05±1.01) vs (6.94±0.72) mmol/L,P<0.01]、LAGE[(8.91±1.57) vs(6.77±1.13)mmol/L,P<0.01]、PT10.0[(11.69±4.18)%vs (4.03±2.50)%,P<0.01]下降,PT3.9[(4.07±3.00)%vs (4.72±2.66)%,P>0.05]变化比较差异无统计学意义. 结论 沙格列汀联合持续皮下输注胰岛素可改善胰岛功能较差的T2DM患者血糖波动,且不增加低血糖事件发生.
Objective To evaluate the efficacy of saxagliptin on blood glucose fluctuations by continuous glucose monitoring system (CGMS) in long-course T2DM patients with poor β-cell function. Methods Thirty T2DM patients with poor β-cell function were treated with insulin-pump for fifteen days. The insulin dose was not adjusted after the tenth day, and saxagliptin was add-on to the previous therapy on the thirteenth to fifteenth days. CGMS was performed for the last five days. The mean amplitude of glycaemic excursion (MAGE), standard deviation of blood glucose ($DBG) and mean blood glucose (MBG), percentage period of hyperglycemia (glucose〉 10.0 mmol/L, PT10.0), percentage period of hypoglycemia (glucose〈3.9 mmol/L,PT3.9) of the patients on the eleventh to twelfth and fourteenth to fifteenth were compared. Results Compared with pre-administration of saxagliptin, the levels of MAGE [(5.28±1.44) vs (3.27_±0. 76)mmol/L,P〈0.01],SDBG [(2.43±0.50) vs (1.79±0.45)mmol/L,P〈 0.01],MBG [(8.05±1.01) vs (6.94±0.72)mmol/L,P〈0. 01],LAGE [(8. 91±1.57)vs(6. 77±1.13) mmol/L,P〈 0. 01 ], PT10.0 [( 11.69 ± 4.18 ) % vs (4.03 ± 2.50) %, P 〈 0.01] were significantly decreased. There was no significant difference on PT3.9 [(4.07±3.00)% vs (4.72± 2. 66)%, P〉 0. 05]. Conclusion Adding saxagliptin on long-course T2DM patients with poor β-cell function receiving insuiin-pump therapy is effective for improving glucose fluctuations without increasing the incidence of hypoglycemic events.
