Objective To identify the best therapy regimen for a patient with rare hypoglycemia due to insulin autoantibody (IAA). Methods We searched The Cochrane Library (Issue 3, 2008), PubMed (1966-July 2009), EMbase (1974-July 2009) and CBM (1978-July 2009) to identify relevant evidence. The quality of the retrieved studies was critically assessed. Results A total of 291 records were retrieved. No clinical guidelines, systematic reviews or clinical randomized studies were identified. Thirty treatment-related studies involving 6 interventions showed that insulin combined with Prednisone was relatively more effective and safer than conventional therapies. Conclusion The steroid treatment might be useful for the improvement of glycamic control in patients with high IAA levels and severe hypoglycemia and hyperglycemia due to insulin antibodies raised against subcutaneously-injected human insulin.
【摘要】 目的 探讨胰岛素强化治疗对2型糖尿病（type 2 diabetes mellitus，T2DM）患者血清脂联素（adiponectin，APN）的影响。 方法 2007年7—12月，研究纳入连续使用胰岛素治疗至少3个月但血糖控制欠佳[6.5%≤糖化血红蛋白（hemoglobin A1c， HbA1c）≤11.0%]的T2DM患者40例，其中男18例，女22例；年龄29~〖JP2〗69岁；平均诊断T2DM病史11年。治疗方案为进行16周的胰岛素强化治疗，血糖控制目标为空腹血糖≤7 mmol/L，〖JP〗餐后2 h血糖≤8 mmol/L。分别于强化治疗前、强化治疗4周后及强化治疗16周后测定HbA1c以及血清APN水平。 结果 与强化治疗前相比，胰岛素治疗4周后空腹及三餐后2 h血糖明显下降（Plt;0.05），但HbA1c和血清APN水平差异无统计学意义（Pgt;0.05）；强化16周后，HbA1c水平明显低于治疗前和治疗4周后且差异具有统计学意义（Plt;0.05），APN水平高于治疗前和治疗4周后且差异有统计学意义（Plt;0.05）。体质量指数在强化治疗16周后明显增加且与强化治疗前和强化治疗后4周相比差异具有统计学意义（Plt;0.05）。APN与空腹血糖（b=-0.225，P=0.013）、早餐后2 h血糖（b=-0.229，P=0.012）呈负相关。 结论 胰岛素强化治疗可以提高T2DM患者血清APN水平。【Abstract】 Objective To investigate the effect of intensive insulin therapy on serum adiponectin (APN) level in patients with type 2 diabetes mellitus (T2DM). Methods Forty patients with T2DM who had undergone insulin therapy for at least three months but with their blood glucose poorly controlled [glycosylated hemoglobin Alc (HbA1c) level ranged from 6.5% to 10.0%] from July to December 2007 were enrolled in this study. There were 18 males and 22 females with their age ranged from 29 to 69 years. They had an average time of T2DM history of 11 years. Intensive insulin therapy was carried out for 16 weeks with a target of less than 7 mmol/L for fasting blood glucose and 8 mmol/L for postprandial blood glucose. HbA1c and serum adiponectin concentrations were detected at baseline, at week 4 after intensive therapy and at the end of the study. Results After 4 weeks of intensive blood glucose control, fasting and postprandial blood glucose levels decreased significantly (Plt;0.05), but the HbA1c and serum APN concentrations did not reduce remarkably (Pgt;0.05). After 16 weeks of treatment, the level of HbA1c was significantly lower than those at baseline and 4 weeks after treatment (Plt;0.05), and serum APN concentration increased significantly (Plt;0.05), compared with those two time points. However, an evident increase of body mass index (BMI) was found while compared with BMI at baseline and 4 weeks after treatment (Plt;0.05). The linear regression analysis indicated that APN was negatively associated with fasting blood glucose (b=-0.225,P=0.013) and blood glucose level 2 hours after breakfast (b=-0.229,P=0.012). Conclusion Intensive insulin therapy can improve serum adiponectin level in type-2 diabetic patients.
