摘要:
[Objective]To compare the efficacy of short-term insulin pump intensification therapy for the treatment of newly diagnosed type 2 diabetes mellitus(T2DM), with different body mass index(BMI). [Methods] According to BMI(BMI≥25 kg/m2 ) , 40 cases of newly diagnosed T2DM were assigned into obesity group(group, n =20) and non-obesity group(NOB group, n =20). Insulin pump intensification therapy was used for both groups for a week. Fasting blood glucose(FBG) , insulin(FINS) , c-peptide(FCP) , 2-hours postprandial glucose(2hPG) and HbA1c were measured on admission. Waist-to-hip ratio(WHR) , insulin resistance index(HOMA-IR) and insulin secretion index(HOMA-β) were calculated. FBG, 2hPG, the days of blood glucose up to the standard and insulin dose between two groups before and after insulin pump intensification therapy were compared. [Results]There were significant differences in WHR, BMI, FINS, FCP, HO-MA-IR and HOMA-β in obesity group between OB group and NOB group( P <0. 01). After insulin pump intensification therapy, blood glucose in two groups reached the standard. The time of blood glucose up to the standard in OB group was obviously shorter than that in NOB group( P <0. 01) , but insulin dose in OB group was higher than that in NOB group( P <0. 05). [Conclusion]Insulin secretion and reserve function in newly diagnosed T2DM with obesity are better. Compared with non-obesity T2DM, blood glucose in T2DM with o-besity after insulin pump intensification therapy can be controlled in an ideal range for a shorter time.%[目的]比较不同体质指数(BMI)的初诊2型糖尿病(T2DM)患者短期胰岛素泵强化治疗效果.[方法]将40例初诊2型糖尿病患者按照BMI≥25 kg/m2分为肥胖组(OB组)与非肥胖组(NOB组),每组20例.两组均进行1周的胰岛素泵强化治疗,检测入院时空腹血糖(FBG)、胰岛素(FINS)和C肽(FCP),餐后2小时血糖(2hPG),糖化血红蛋白(HbA1c),计算腰臀比(WHR)、胰岛素抵抗指数(HOMA-IR)及胰岛素分泌指数(HOMA-β),比较胰岛素泵强化治疗前后两组FBG、2hPG,血糖达标天数及达标时胰岛素日用量的差异.[结果]OB组较NOB组WHR、BMI、FINS、FCP、HOMA-IR及HOMA-β差异有显著性( P <0.01),胰岛素泵强化治疗后均可使两组血糖达标,OB组较NOB组达标时间明显缩短( P <0.01),但OB组胰岛素用量高于NOB组( P <0.05).[结论]初诊肥胖型T2DM患者胰岛素分泌及储备功能较好,经短期胰岛素泵强化治疗后,较非肥胖型T2DM能在较短时间内将血糖控制在理想的范围.
