Background

Gestational diabetes mellitus (GDM) is known to increase the risk of cardiovascular diseases. Measuring the carotid artery intimal-medial thickness (CIMT) is a non-invasive technique used to evaluate early atherosclerosis and to predict future cardiovascular diseases. We examined the association between CIMT and cardiovascular risk factors in young Korean women with previous GDM.

Methods

One hundred one women with previous GDM and 19 women who had normal pregnancies (NP) were recruited between 1999 and 2002. At one year postpartum, CIMT was measured using high-resolution B-mode ultrasonography, and oral glucose tolerance tests were performed. Fasting glucose, glycated hemoglobin A1c (HbA1c), insulin levels and lipid profiles were also measured. CIMTs in the GDM and NP groups were compared, and the associations between CIMT and cardiovascular risk factors were analyzed in the GDM group.

Results

CIMT results of the GDM group were not significantly different from those of the NP group (GDM, 0.435±0.054 mm; NP, 0.460±0.046 mm; P=0.069). In the GDM group, a higher HbA1c was associated with an increase in CIMT after age adjustment (P=0.011). CIMT results in the group with HbA1c >6.0% were higher than those of the normal HbA1c (HbA1c ≤6.0%) (P=0.010). Nine of the patients who are type 2 diabetes mellitus converters within one year postpartum but showed no significant difference in CIMT results compared to NP group.

Conclusion

Higher HbA1c is associated with an increase in CIMT in women with previous GDM. However, CIMT at one year postpartum was not increased in these women compared to that in NP women.

Background

Sulfonylurea primarily stimulates insulin secretion by binding to its receptor on the pancreatic β-cells. Recent studies have suggested that sulfonylureas induce insulin sensitivity through peroxisome proliferator-activated receptor γ (PPARγ), one of the nuclear receptors. In this study, we investigated the effects of sulfonylurea on PPARγ transcriptional activity and on the glucose uptake via PPARγ.

Methods

Transcription reporter assays using Cos7 cells were performed to determine if specific sulfonylureas stimulate PPARγ transactivation. Glimepiride, gliquidone, and glipizide (1 to 500 µM) were used as treatment, and rosiglitazone at 1 and 10 µM was used as a control. The effects of sulfonylurea and rosiglitazone treatments on the transcriptional activity of endogenous PPARγ were observed. In addition, 3T3-L1 adipocytes were treated with rosiglitazone (10 µM), glimepiride (100 µM) or both to verify the effect of glimepiride on rosiglitazone-induced glucose uptake.

Results

Sulfonylureas, including glimepiride, gliquidone and glipizide, increased PPARγ transcriptional activity, gliquidone being the most potent PPARγ agonist. However, no additive effects were observed in the presence of rosiglitazone. When rosiglitazone was co-treated with glimepiride, PPARγ transcriptional activity and glucose uptake were reduced compared to those after treatment with rosiglitazone alone. This competitive effect of glimepiride was observed only at high concentrations that are not achieved with clinical doses.

Conclusion

Sulfonylureas like glimepiride, gliquidone and glipizide increased the transcriptional activity of PPARγ. Also, glimepiride was able to reduce the effect of rosiglitazone on PPARγ agonistic activity and glucose uptake. However, the competitive effect does not seem to occur at clinically feasible concentrations.

Background

Our goal was to investigate the effects of low intensity resistance training on body fat, muscle mass and strength, cardiovascular fitness, and insulin sensitivity in type 2 diabetes.

Methods

Twenty-eight overweight women with type 2 diabetes were randomly assigned to a resistance training group (RG, n = 13) or a control group (CG, n = 15). RG performed resistance training using elastic bands, of which strength was equal to 40 to 50% of one repetition maximum (1RM), for three days per week. Each exercise consisted of three sets for 60 minutes. We assessed abdominal fat using computed tomography, muscle mass using dual-energy X-ray absorptiometry, and muscle strength using Keiser's chest and leg press. Insulin sensitivity was measured using the insulin tolerance test, and aerobic capacity was expressed as oxygen uptake at the anaerobic threshold (AT-VO2) before and after the 12-week exercise program.

Results

The age of participants was 56.4 ± 7.1 years, duration of diabetes was 5.9 ± 5.5 years, and BMI was 27.4 ± 2.5 kg/m2, without significant differences between two groups. During intervention, a greater increase in muscle mass and greater decreases in both total fat mass and abdominal fat were observed in RG compared to those of CG (P = 0.015, P = 0.011, P = 0.010, respectively). Increase in 1RM of upper and lower extremities was observed in the RG (P = 0.004, P = 0.040, respectively), without changes in AT-VO2 and insulin resistance in either group.

Conclusion

In conclusion, the low intensity resistance training was effective in increasing muscle mass and strength and reducing total fat mass without change of insulin sensitivity in type 2 diabetic patients.

BACKGROUND
Weight loss through low-calorie diets (LCDs) decreases visceral fat (VF). However, the effects on muscle mass, changes of dietary quality, and insulin sensitivity are unknown for Korean obese type 2 diabetic subjects. Therefore, this study examined such effects of LCDs. METHODS: A total of 30 obese type 2 diabetic subjects (body mass index, 27.0 +/- 2.2 kg/m2) were randomly assigned to an LCD or control group. Subjects on LCDs took 500~1,000 kcal fewer energy than their usual dietary intake (1,000~1,500 kcal/day) over the course of 12 weeks. The abdominal VF and femoral muscle mass were evaluated by computed tomography, and insulin sensitivity was assessed using an insulin tolerance test (Kitt; rate constant for plasma glucose disappearance, %/min). Dietary nutrient intake consumed by subjects was assessed by 3-day food records. RESULTS: The percent VF reduction was -23.4 +/- 17.2% in the LCD group and -9.8 +/- 11.8% in the control group after 12 weeks (P < 0.001, P = 0.002). However, significant decrease in femoral mass or proportional change of marcronutrient intake and mean adequacy ratio were not found in the LCD group, as compared to the control group. Insulin sensitivity improved in the LCD group, as compared to the control group (P = 0.040). CONCLUSION: LCD effectively improved insulin sensitivity and reduced abdominal VF without reduction of femoral muscle and dietary quality in obese type 2 diabetic subjects.

AbstractAbstract PDF
BACKGROUND
Combination fitness regimens (including aerobic and resistance exercises) are effective for improving cardio-respiratory fitness, reducing visceral fat and increasing insulin sensitivity in diabetic patients. The combination exercise intensity that a patient is capable of is limited by his or her aerobic capacity and one repetition maximum (1RM). We investigated the relationships between 1RM, aerobic exercise capacity and body mass index in patients with type 2 diabetes. METHODS: A total of 177 (men: 85, women: 92) diabetic subjects with HbA1c < or = 10% were enrolled. Muscle strength and 1RM were assessed bychest press (upper body) and leg press (lower body). We assessed aerobic capacity by VO2max and muscle mass by bioimpedance analysis. RESULTS: There was no correlation between 1RM and VO2max in type 2 diabetic patients (upper: P = 0.122, lower: P = 0.138 for men, and upper: P = 0.952, lower: P = 0.570 for women). However, 1RM was significantly correlated with muscle mass both in men and women (upper: r = 0.493, P < 0.001, r = 0.315, P = 0.002 lower: r = 0.437 P < 0.001, r = 0.307, P =0.003, respectively). There was also a significant correlation between 1RM and BMI. In obese male subjects with BMI > or = 25 kg/m2, we observed a significant correlation between muscle mass and BMI (r = 0.374, P = 0.032), but this correlation was not observed in women. CONCLUSION: Clinicians treating Korean type 2 diabetic subjects should recommend resistance exercise to their patients. In particular, obese women with diabetes may receive greater benefits by increasing muscle mass through resistance exercises.

AbstractAbstract PDF
BACKGROUND
It is difficult to improve muscle strength with only aerobic exercise training in type 2 diabetes patients. Resistance training is effective for improving muscle mass, muscle strength and insulin sensitivity. One repetition maxima (1RM), or the maximum amount of weight a subject can lift in a single repetition, may be a useful unit for evaluating the results of resistance training in type 2 diabetic patients. This study was aimed to assess baseline values for 1RM in a sample of Korean type 2 diabetes mellitus patients that are scaled for intensity and load of exercise, and to assess the relationship of 1RM to age. METHODS: A total of 266 (male: 95, female: 171) Korean patients with type 2 diabetes mellitus were included in the study sample. Maximal muscle strength was assessed by measuring 1RM for each subject (KEISER, Fresno, CA, USA). Two different exercises were used to measure 1RM: the chest press for the upper extremities, and the leg press for the lower extremities. RESULTS: Both upper and lower values of 1RM decreased with age in men and women; upper 1RM: r = -0.454, P<0.001 in men, r = -0.480, P< 0.001 in women, lower 1RM: r = -0.569, P<0.001 in men, and r = -0.452, P<0.001 in women. Values of 1RM significantly decreased in men only after the age of 70. In women, values of 1RM continuously decreased after the age of 60. CONCLUSION: The maximal muscle strength of individuals with type 2 diabetes decreases with age. We believe that resistance training is especially beneficial for type 2 diabetes mellitus patients after the sixth decade of life.

AbstractAbstract PDF
BACKGROUND
Exercise offers protection against atherosclerosis and insulin resistance. We evaluated the benefits of exercise at different levels of intensity for ameliorating inflammation, endothelial dysfunction, and insulin resistance in a sample of type 2 diabetic subjects. METHODS: Fifty-nine overweight women with type 2 diabetes were randomly assigned to control (CG, N = 18), moderate-intensity exercise (MEG, N = 17), and vigorous-intensity exercise (VEG, N = 14) groups. Patients in the two experimental groups completed a 12-week exercise program, with their exercise activities monitored by accelerometers. We assessed the patients' body weights, total abdominal fat (TF), subcutaneous fat (SF) and visceral fat (VF) via computed tomography, measurements of plasma levels of hs-C-reactive protein (hs-CRP) and interleukin-6 (IL-6), assessment of endothelial function by brachial artery flow-mediated dilation (FMD), and evaluation of insulin sensitivity by insulin tolerance tests, at baseline, at the end of the 12-week interventions, and one year after initiation of the study. RESULTS: At baseline, the average age of all subjects was 54 +/- 7 years, and average body mass index (BMI) was 26.9 +/- 2.5 kg/m2. During the intervention, patients in the MEG and VEG groups expended comparable amounts of activity-related calories (488.6 +/- 111.9 kcal/day, 518.8 +/- 104.1 kcal/day, respectively). Although BMI, TF, and SF decreased similarly in the MEG and VEG groups (deltaBMI: -1.1 +/- 0.7, -0.8 +/- 0.5, deltaTF: -4,647 +/- 3,613 mm2, -2,577 +/- 2,872 mm2, deltaSF: -2,057 +/- 2,021 mm2, -1,141 +/- 1,825 mm2, respectively), compared to control (P<0.01), hs-CRP, IL-6, and FMD remained constant in both exercise groups even after completion of the 12-week exercise intervention. Insulin sensitivity improved only in patients subjected to vigorous exercise (VEG). Visceral fat loss was observed only in patients subjected to moderate exercise (MEG). At one-year follow up, these values had all returned to baseline. CONCLUSION: Exercise vigorous enough to result in significant weight and fat reduction did not ameliorate inflammation and endothelial dysfunction as measured at the end of a 12-week exercise intervention, nor did it result in sustained improvements in insulin sensitivity in type 2 diabetic subjects.

AbstractAbstract PDF
BACKGROUND
The results of previous studies suggest that portion size is a major factor dictating dietary energy intake. We investigated the relationship between frequencies of rice meals, bowl volumes, and dietary energy intake in a sample of patients with type 2 diabetes. METHODS: A total of 203 type 2 diabetes patients were enrolled in the study. A one-week food diary was collected from each patient and used to assess the types of meal consumed as well as the context of consumption. The volumes of the eating vessels (rice, soup and side dish bowls) used by each patient were obtained by comparisons to measuring cylinders, and dietary energy and macronutrient intake were estimated for each patient by consulting three-day dietary records. RESULTS: The mean age of the 203 subjects (male: 76, female: 127) was 53.9 +/- 9.1 years and the average body mass index (BMI) was 25.6 +/- 4.2 kg/m2. Among the subjects who ate three times per day, 96.4% consumed rice more than twice out of three meals. The median volume of rice bowls used by patients was 350 cc, of soup bowls was 530 cc and of side dish bowls was 260 cc. Portion size, as estimated by rice bowl volume, was not associated with BMI. Male subjects tended to eat out of larger rice and soup bowls (P < 0.001). Portion size was correlated with energy intake from rice (P = 0.021), but not with total energy intake (kcal/kg/day), especially in male subjects. CONCLUSION: Portion size of rice bowl was correlated with energy intake from rice, but not with total energy intake in male subjects with type 2 diabetes. To design effective meal planning methods for patients with type 2 diabetes, further prospective studies are warranted to investigate causative relationships between portion size andmetabolic conditions as well as variation by gender.

AbstractAbstract PDF
BACKGROUND
Skeletal muscle is the most important tissue contributing to insulin resistance. Several studies have shown that accumulation of intramyocellular lipid is associated with the development of insulin resistance. Thus, proteins involved in lipid transport, storage and metabolism might also be involved in insulin action in skeletal muscle. Adipose differentiation-related protein (ADRP), which is localized at the surface of lipid droplets, is known to be regulated by peroxisome proliferator activated receptor gamma (PPARgamma). However, it is not known whether ADRP plays a role in regulating glucose uptake and insulin action in skeletal muscle. METHODS: ADRP expression in skeletal muscle was measured by RT-PCR and western blot in db/db mice with and without PPARgamma agonist. The effect of PPARgamma agonist or high lipid concentration (0.4% intralipos) on ADRP expression was also obtained in cultured human skeletal muscle cells. Glucose uptake was measured when ADRP was down-regulated with siRNA or when ADRP was overexpressed with adenovirus. RESULTS: ADRP expression increased in the skeletal muscle of db/db mice in comparison with normal controls and tended to increase with the treatment of PPARgamma agonist. In cultured human skeletal muscle cells, the treatment of PPARgamma agonist or high lipid concentration increased ADRP expression. siADRP treatment decreased both basal and insulin-stimulated glucose uptake whereas ADRP overexpression increased glucose uptake in cultured human skeletal muscle cells. CONCLUSION: ADRP expression in skeletal muscle is increased by PPARgamma agonist or exposure to high lipid concentration. In these conditions, increased ADRP contributed to increase glucose uptake. These results suggest that insulin-sensitizing effects of PPARgamma are at least partially achieved by the increase of ADRP expression, and ADRP has a protective effect against intramyocellular lipid-induced insulin resistance.

AbstractAbstract PDF
Autoantibody negative fulminant type 1 diabetes mellitus is a novel subtype of type 1 diabetes, which is characterized by a remarkably abrupt onset, metabolic derangement such as diabetic ketoacidosis at diagnosis, low HbA1c level at onset and a negative islet-related autoantibodies. The prevalence of fulminant type 1 diabetes has large difference between Japan and other countries. The precise reason for this regional variation remains to be clarified. One of the possible explanations is genetic background such as genotype of class II HLA molecule.
