摘要
目的探讨2型糖尿病患者接受持续皮下胰岛素输注(CSII)治疗时CSII对胰岛功能评估的影响。方法2015年5至12月于中山大学附属第三医院内分泌与代谢病学科住院的125例2型糖尿病患者停用原降糖药物1d后检测空腹血糖、糖化血红蛋白、血脂、C肽(空腹、固定餐餐后30min、2h),检测后接受CSII治疗。血糖达标后在继续使用CSII的情况下检测空腹、固定餐餐后30min、2hC肽。检测当天晚上22时开始停止CSII治疗,第2天重复前1天检测。结果与CSII治疗前比较,停CSII后空腹[(0.41±0.16)比(0.35±0.20)nmol/L,P=0.015]、餐后30min[(0.71±0.33)比(0.57±0.31)nmol/L,P=0.005]、餐后2h[(1.37±0.75)比(0.84±0.54)nmol/L,P〈0.001]C肽水平均较治疗前各相应时间点C肽水平升高,而停CSII前空腹[(0.23±0.13)nmol/L]、餐后30min[(n39±0.26)nmol/L]、餐后2h[(0.67±0.50)nmol/L]C肽水平则低于治疗前相应时间点C肽水平(P〈0.001,P〈0.001,P=0.023)。经CSⅡ治疗后,停CSⅡ后各时间点的C肽水平较停CSⅡ前明显升高(均P〈0.001),各时间点C肽升高百分比分别为:141%(空腹)、127%(餐后1h)及219%(餐后2h)。结论为提高评估胰岛功能的准确性,使用CSII治疗的2型糖尿病患者评估胰岛功能时最好停用CSⅡ。
Objective To evaluate the impact of continuous subcutaneous insulin infusion (CSII) on β-cell function assessment. Methods One hundred and twenty-five patients with type 2 diabetes (T2DM) admitted to Third Affiliated Hospital of Sun Yat-sen University treated with CSII were enrolled from May to December 2015. Blood samples were collected to measure their fasting blood glucose, haemoglobin Alc, blood lipids and plasma C peptide levels (fasting, 30 min and 120 rain after a mixed meal) on the next day of their admission before CSII started. When patients achieved the target of fasting capillary glucose ≤ 7. 0 mmol/L, C-peptide levels (0 min, 30 min and 120 min after a mixed meal) were measured. Then CSII were stopped at 10 pm with the same tests repeated on the next day. Results Compared with those measured before CSII [0 min: (0. 35 ± 0. 20) nmol/L, 30 min: (0. 57 ± 0. 31 ) nmol/L, 120 min: (0. 84 ±0. 54) nmol/L], C-peptide levels after stopping CSII at all time points [0 min: (0.41 ± 0. 16) nmo]/L, 30 min: (0. 71±0. 33) nmol/L, 120 min: (1.37 ±0. 75) nmol/L] increased (P=0. 015, P= 0. 005, P 〈 0. 001 ) even glucose control was achieved, but significantly decreased immediately before CSII was stopped [0 min: (0. 23 ±0. 13)nmol/L, 30 rain: (0. 39 ±0. 26) nmol/L, 120 min: (0. 67± 0. 50) nmol/L] (P 〈 0.001, P 〈 0. 001, P = 0. 023). The C-peptide after stopping CSII increased to 141% (0 min), 127% (30 min) and 219% (120 min) respectively compared to those before stopping CSII. Conclusion CSII therapy should be stopped for accurate evaluation of β-cell function due to its " β-cell rest" effect in T2DM.
