Comparison of glargine insulin versus rosiglitazone addition in poorly controlled type 2 diabetic patients on metformin plus sulfonylurea

OBJECTIVE: We sought to examine the mechanisms by which the addition of glargine insulin or rosiglitazone improves glycemic control in type 2 diabetic subjects poorly controlled on maximally effective doses of metformin plus sulfonylurea. RESEARCH DESIGN AND METHODS: Subjects (aged 47 +/- 11 years, BMI 31 +/- 5 kg/m(2), HbA(1c) [A1C] 9.4 +/- 1.3%) received bedtime glargine insulin (titrated based on the fasting plasma glucose [FPG], n = 10) or rosiglitazone (4 mg twice daily, n = 10). At baseline and after 4 months, A1C was measured and an oral glucose tolerance test and a 3-h euglycemic insulin (80 mU/m(2) per min) clamp with [3-(3)H]glucose were performed. RESULTS: A1C and FPG decreased similarly in the glargine insulin (9.1 +/- 0.4 to 7.6 +/- 0.3% and 212 +/- 14 to 139 +/- 5 mg/dl, respectively, both P < 0.0001) and rosiglitazone (9.4 +/- 0.3 to 7.6 +/- 0.4% and 223 +/- 14 to 160 +/- 19 mg/dl, respectively, both P < 0.005) groups. After 4 months, endogenous glucose production (EGP) declined similarly with glargine insulin (2.27 +/- 0.10 to 1.73 +/- 0.12 mg . kg(-1) . min(-1), P < 0.0001) and rosiglitazone (2.21 +/- 0.12 to 1.88 +/- 0.12 mg . kg(-1) . min(-1), P = 0.01). The hepatic insulin resistance index declined in the rosiglitazone group (32 +/- 3 to 21 +/- 1 mg . kg(-1) . min(-1) x microU/ml, P = 0.03 vs. baseline and P < 0.05 vs. glargine insulin) and did not change in the glargine group (22 +/- 5 to 20 +/- 3 mg . kg(-1) . min(-1) x microU/ml, P = NS). At 4 months, glargine insulin (3.6 +/- 0.5 to 4.2 +/- 0.4 mg . kg(-1) . min(-1), P < 0.01) and rosiglitazone (2.7 +/- 0.3 to 3.8 +/- 0.3 mg . kg(-1) . min(-1), P < 0.0005) increased R(d), but the increment was greater in the rosiglitazone group (P < 0.05). Diastolic blood pressure was reduced only by rosiglitazone (P < 0.01). CONCLUSIONS: Triple therapy with glargine insulin or rosiglitazone similarly reduced A1C, primarily by suppressing basal EGP (hepatic). Glargine insulin reduced basal EGP by increasing plasma insulin levels, while rosiglitazone decreased basal hepatic glucose production by improving hepatic insulin sensitivity.     

罗格列酮钠对2型糖尿病合并与不合并非酒精性脂肪肝患者疗效和安全性的比较

目的观察罗格列酮钠对血糖控制未达标的2型糖尿病(T2DM)合并与不合并非酒精性脂肪肝(NAFL)患者的降糖疗效和安全性。方法 2009年1月-2011年1月60例仅用磺脲类和二甲双胍治疗血糖控制未达标的T2DM患者,按合并和不合并NAFL分为观察组和对照组各30例,两组均在原口服降糖药基础上联合加用国产罗格列酮钠4 mg 1次/d,治疗共3个月,观察治疗前后的血糖、胰岛素、糖化血红蛋白(HbA1c)、体质量指数(BMI)、血脂、肝功、血压水平以及药物不良反应,并比较治疗后的血糖达标率。结果两组患者治疗后的空腹血糖(FPG)、餐后2 h血糖(2hPG)、HbA1c、空腹胰岛素、甘油三酯和极低密度脂蛋白胆固醇均较治疗前下降,高密度脂蛋白胆固醇较治疗前升高(P<0.05),而丙氨酸转氨酶、总胆固醇、低密度脂蛋白胆固醇及血压无明显变化(P>0.05),但观察组治疗后的FPG和2hPG均较对照组下降更明显(P<0.01),且血糖达标率为73.3%,显著高于对照组的46.7%(P<0.05),同时观察组餐后2 h胰岛素(2hINS)水平在治疗前后均明显高于对照组而且治疗后有显著下降(P<0.01),但对照组治疗后2hINS虽然也有下降但无统计学意义(P>0.05)。观察组治疗前后BMI无明显变化,但对照组治疗后BMI有明显的升高(P<0.05)。结论国产罗格列酮钠片对血糖控制未达标的T2DM合并和不合并NAFL患者均有进一步降低血糖、HbA1c以及改善血脂的作用,但对T2DM合并NAFL的患者的降糖疗效更显著,未见加重肝功能损坏,不良反应小,可作为此类患者联合用药的一种选择。

背景:针刺治疗2型糖尿病具有很好的疗效。目的:观察针刺对2型糖尿病模型大鼠胰岛β细胞胰岛素表达的影响。方法:将糖尿病模型大鼠按随机化原则分为针刺组、西药组、模型组,同时设置正常对照组。针刺组大鼠取足三里、内庭和胰俞穴给予针刺治疗,西药组用罗格列酮0.2mg/kg灌胃,模型组用双蒸水2mL/kg灌胃,均1次/d,连续4周。结果与结论:①血糖:针刺组明显低于模型组、西药组(P<0.05)。②血脂:针刺组胆固醇和三酰甘油低于模型组(P<0.05);高密度脂蛋白胆固醇明显高于模型组(P<0.01)。针刺组三指标与西药组比较差异无显著性意义。③胰岛β细胞胰岛素表达:针刺组显著高于模型组和西药组(P<0.05)。④胰岛形态:模型组与西药组胰岛结构不完整,结构破坏,胰岛素染色效果差;针刺组胰岛结构趋向完整,胰岛素染色颗粒明显。说明针刺可显著提高2型糖尿病模型大鼠胰岛β细胞胰岛素表达水平,有效改善胰岛β细胞功能。     

The combined effect of triple therapy with rosiglitazone, metformin, and insulin aspart in type 2 diabetic patients

OBJECTIVE: Type 2 diabetes is caused by reduced insulin secretion and insulin resistance in skeletal muscle and liver. We tested the combination therapy with insulin aspart, rosiglitazone, and metformin with the purpose of treating all three defects in order to test the hypothesis that this "triple therapy" will normalize glucose metabolism. RESEARCH DESIGN AND METHODS: Sixteen obese type 2 diabetic outpatients on human NPH or MIX (regular + NPH insulin) insulin twice daily were randomized to either triple therapy, i.e., insulin aspart (a rapid-acting insulin analog) at meals, metformin (which improves hepatic insulin sensitivity), and rosiglitazone (which improves peripheral insulin sensitivity), or to continue their NPH or MIX insulin twice daily for 6 months. Insulin doses were adjusted in both groups based on algorithms. HbA(1c), insulin dose, hypoglycemic episodes, insulin sensitivity (clamp), hepatic glucose production (tracer), and diurnal profiles of plasma glucose and insulin were used in evaluating treatment. RESULTS: In the triple therapy group, HbA(1c) declined from 8.8 to 6.8% (P < 0.01) without inducing severe hypoglycemic events. Postprandial hyperglycemia was generally avoided, and the diurnal profile of serum insulin showed fast and high peaks without any need to increase insulin dose. In the control group, the insulin dose was increased by 50%, but nevertheless both HbA(1c) and 24-h blood glucose profiles remained unchanged. Insulin sensitivity improved in both skeletal muscle and the liver in the triple therapy group, whereas no change was observed in the control group. CONCLUSIONS: We conclude that treatment of the three major pathophysiological defects in type 2 diabetic subjects by triple therapy significantly improved glucose metabolism in obese type 2 diabetic subjects.     

Vascular effects of improving metabolic control with metformin or rosiglitazone in type 2 diabetes

OBJECTIVE: The aim of this study was to test whether vascular reactivity is modified by improving metabolic control and peripheral insulin resistance in type 2 diabetes. RESEARCH DESIGN AND METHODS: In a randomized, double-blind design, we assigned 74 type 2 diabetic patients to rosiglitazone (8 mg/day), metformin (1,500 mg/day), or placebo treatment for 16 weeks and measured insulin sensitivity (euglycemic insulin clamp), ambulatory blood pressure, and forearm blood flow response to 1) intra-arterial acetylcholine (ACh), 2) intra-arterial nitroprusside, 3) the clamp, and 4) blockade of nitric oxide (NO) synthase. RESULTS: Compared with 25 nondiabetic subjects, patients had reduced insulin sensitivity (30 +/- 1 vs. 41 +/- 3 micromol. min(-1). kg fat-free mass(-1); P < 0.001) and reduced maximal response to ACh (586 +/- 42 vs. 883 +/- 81%; P < 0.001). Relative to placebo, 16 weeks of rosiglitazone and metformin similarly reduced fasting glucose (-2.3 +/- 0.5 and -2.3 +/- 0.5 mmol/l) and HbA(1c) (-1.2 +/- 0.3 and -1.6 +/- 0.3%). Insulin sensitivity increased with rosiglitazone (+6 +/- 3 micromol. min(-1). kg fat-free mass(-1); P < 0.01) but not with metformin or placebo. Ambulatory diastolic blood pressure fell consistently (-2 +/- 1 mmHg; P < 0.05) only in the rosiglitazone group. Nitroprusside dose response, clamp-induced vasodilatation, and NO blockade were not affected by either treatment. In contrast, the slope of the ACh dose response improved with rosiglitazone (+40% versus baseline, P < 0.05, +70% versus placebo, P < 0.005) but did not change with either metformin or placebo. This improvement in endothelium-dependent vasodilatation was accompanied by decrements in circulating levels of free fatty acids and tumor necrosis factor-alpha. CONCLUSIONS: At equivalent glycemic control, rosiglitazone, but not metformin, improves endothelium dependent vasodilatation and insulin sensitivity in type 2 diabetes.     

The effect of rosiglitazone on overweight subjects with type 1 diabetes

OBJECTIVE: To evaluate the safety and effectiveness of rosiglitazone in the treatment of overweight subjects with type 1 diabetes. RESEARCH DESIGN AND METHODS: A total of 50 adult type 1 diabetic subjects with a baseline BMI > or =27 kg/m(2) were randomly assigned in a double-blind fashion to take insulin and placebo (n = 25) or insulin and rosiglitazone 4 mg twice daily (n = 25) for a period of 8 months. Insulin regimen and dosage were modified in all subjects to achieve near-normal glycemic control. RESULTS: Both groups experienced a significant reduction in HbA(1c) (A1C) level (rosiglitazone: 7.9 +/- 1.3 to 6.9 +/- 0.7%, P < 0.0001; placebo: 7.7 +/- 0.8 to 7.0 +/- 0.9%, P = 0.002) and a significant increase in weight (rosiglitazone: 97.2 +/- 11.8 to 100.6 +/- 16.0 kg, P = 0.008; placebo: 96.4 +/- 12.2 to 99.1 +/- 15.0, P = 0.016). Baseline measures of BMI (P = 0.001), total daily insulin dose (P = 0.002), total cholesterol (P = 0.005), HDL cholesterol (P = 0.001), and LDL cholesterol (P = 0.02) were predictors of improvement in A1C level only in the group treated with rosiglitazone. Total daily insulin dose increased in subjects taking placebo (74.0 +/- 33.8 to 82.0 +/- 48.9 units, P < 0.05 baseline vs. week 32), but it decreased slightly in subjects taking rosiglitazone (77.5 +/- 28.6 to 75.3 +/- 33.1 units). Both systolic blood pressure (137.4 +/- 15.6 vs. 128.8 +/- 14.8 mmHg, baseline vs. week 32, P < 0.02) and diastolic blood pressure (87.2 +/- 9.4 vs. 79.4 +/- 7.2 mmHg, P < 0.0001) improved in the group treated with rosiglitazone. The total incidence of hypoglycemia did not differ between groups. CONCLUSIONS: Rosiglitazone in combination with insulin resulted in improved glycemic control and blood pressure without an increase in insulin requirements, compared with insulin- and placebo-treated subjects, whose improved glycemic control required an 11% increase in insulin dose. Weight gain and hypoglycemia were similar in both groups at the end of the study. The greatest effect of rosiglitazone occurred in subjects with more pronounced markers of insulin resistance.

Addition of biphasic insulin aspart 30 to rosiglitazone in type 2 diabetes mellitus that is poorly controlled with glibenclamide monotherapy

BACKGROUND: The incidence of type 2 diabetes mellitus (DM) is rapidly increasing worldwide. Results from large-scale studies show that tight blood glucose (BG) control improves the outcome of patients with type 2 DM. OBJECTIVE: This trial assessed the short-term efficacy and tolerability of adding a thiazolidinedione (rosiglitazone [ROS]) to existing sulfonylurea (SU) therapy (glibenclamide) compared with switching to combination treatment with a premixed insulin (biphasic insulin aspart 30 [BIAsp 30], a rapid-acting insulin analog) and the thiazolidinedione in a select group of patients with type 2 DM whose metabolic control was inadequate with SU monotherapy. METHODS: In this 6-week, multicenter, open-label, parallel-group trial, patients with type 2 DM whose BG level was not adequately controlled with glibenclamide monotherapy (glycosylated hemoglobin [HbA1c] 8%-13%) were randomized either to replace glibenclamide with BIAsp 30 (individually titrated dosages starting with 6-8 U BID) plus rosiglitazone (4 mg once daily) (BIAsp 30 + ROS group) or to add rosiglitazone (4 mg once daily) to their pretrial doses of glibenclamide (GLIB + ROS group). Patients measured their BG levels immediately before each of the 3 main meals, 90 minutes after the start of each meal, and at bedtime, and mean BG levels were calculated at weeks 0 (baseline), 1, 2, 4, 6, and at 2-week follow-up (week 8). The primary end point was change in mean daily BG level during treatment. Secondary end points included preprandial, postprandial, and bedtime BG levels, serum fructosamine level HbA, and fasting BG level, which were measured at each study visit. Tolerability was assessed using hematologic and biochemical parameters, vital signs, and physical examination. RESULTS: Forty-nine patients (32 men, 17 women; mean [SD] age, 59.1 [8.9] years; mean [SD] body mass index, 27.7 [3.7] kg/m2) participated in the study. A significant difference was found between treatments in the change in mean daily BG level from baseline to week 6 (P=0.01). After the 6-week treatment period, change in mean serum fructosamine level was significantly greater for BIAsp 30 + ROS compared with GLIB + ROS (P=0.02). HbA1c decreased in both treatment groups from baseline to study end, but the difference between groups was nonsignificant. The changes in fasting BG from baseline to study end also were nonsignificant between groups. Both combinations were well tolerated. CONCLUSIONS: This short-term study in patients with type 2 DM whose BG level was poorly controlled with glibenclamide monotherapy suggests that switching to a combination of BIAsp 30 + ROS was efficacious and well tolerated and provided an alternative to adding rosiglitazone to existing glibenclamide treatment. The study also suggests that BIAsp 30 may be associated with greater improvements in short-term metabolic control.
