Background

Combination of metformin to reduce the fasting plasma glucose level and an α-glucosidase inhibitor to decrease the postprandial glucose level is expected to generate a complementary effect. We compared the efficacy and safety of a fixed-dose combination of voglibose plus metformin (vogmet) with metformin monotherapy in drug-naïve newly-diagnosed type 2 diabetes mellitus.

Methods

A total of 187 eligible patients aged 20 to 70 years, with a glycosylated hemoglobin (HbA1c) level of 7.0% to 11.0%, were randomized into either vogmet or metformin treatments for 24 weeks. A change in the HbA1c level from baseline was measured at week 24.

Results

The reduction in the levels of HbA1c was −1.62%±0.07% in the vogmet group and −1.31%±0.07% in the metformin group (P=0.003), and significantly more vogmet-treated patients achieved the target HbA1c levels of <6.5% (P=0.002) or <7% (P=0.039). Glycemic variability was also significantly improved with vogmet treatment, estimated by M-values (P=0.004). Gastrointestinal adverse events and hypoglycemia (%) were numerically lower in the vogmet-treated group. Moreover, a significant weight loss was observed with vogmet treatment compared with metformin (−1.63 kg vs. −0.86 kg, P=0.039).

Conclusion

Vogmet is a safe antihyperglycemic agent that controls blood glucose level effectively, yields weight loss, and is superior to metformin in terms of various key glycemic parameters without increasing the risk of hypoglycemia.

Background

We compared the efficacies of vildagliptin (50 mg twice daily) relative to pioglitazone (15 mg once daily) as an add-on treatment to metformin for reducing glycosylated hemoglobin (HbA1c) levels in Korean patients with type 2 diabetes.

Methods

The present study was a multicenter, randomized, active-controlled investigation comparing the effects of vildagliptin and pioglitazone in Korean patients receiving a stable dose of metformin but exhibiting inadequate glycemic control. Each patient underwent a 16-week treatment period with either vildagliptin or pioglitazone as an add-on treatment to metformin.

Results

The mean changes in HbA1c levels from baseline were –0.94% in the vildagliptin group and –0.6% in the pioglitazone group and the difference between the treatments was below the non-inferiority margin of 0.3%. The mean changes in postprandial plasma glucose (PPG) levels were –60.2 mg/dL in the vildagliptin group and –38.2 mg/dL in the pioglitazone group and these values significantly differed (P=0.040). There were significant decreases in the levels of total, low density lipoprotein, high density lipoprotein (HDL), and non-HDL cholesterol in the vildagliptin group but increases in the pioglitazone group. The mean change in body weight was –0.07 kg in the vildagliptin group and 0.69 kg in the pioglitazone group, which were also significantly different (P=0.002).

Conclusion

As an add-on to metformin, the efficacy of vildagliptin for the improvement of glycemic control is not inferior to that of pioglitazone in Korean patients with type 2 diabetes. In addition, add-on treatment with vildagliptin had beneficial effects on PPG levels, lipid profiles, and body weight compared to pioglitazone.

Background

We evaluated the disease profile and clinical management, including the status of both glycemic control and complications, in patients with diabetes who were transferred to referral hospitals in Korea.

Methods

Patients referred to 20 referral hospitals in Gyeongsangnam/Gyeongsangbuk-do and Jeollanam/Jeollabuk-do with at least a 1-year history of diabetes between January and June 2011 were retrospectively reviewed using medical records, laboratory tests, and questionnaires.

Results

A total of 654 patients were enrolled in the study. In total, 437 patients (67%) were transferred from clinics and 197 (30%) patients were transferred from hospitals. A total of 279 patients (43%) visited higher medical institutions without a written medical request. The main reason for the referral was glycemic control in 433 patients (66%). Seventy-three patients (11%) had received more than one session of diabetic education. Only 177 patients (27%) had been routinely self-monitoring blood glucose, and 146 patients (22%) were monitoring hemoglobin A1c. In addition, proper evaluations for diabetic complications were performed for 74 patients (11%). The most common complication was neuropathy (32%) followed by nephropathy (31%). In total, 538 patients (82%) had been taking oral hypoglycemic agents. A relatively large number of patients (44%) had been taking antihypertensive medications.

Conclusion

We investigated the clinical characteristics of diabetic patients and identified specific problems in diabetic management prior to the transfer. We also found several problems in the medical system, which were divided into three medical institutions having different roles in Korea. Our findings suggested that the relationships among medical institutions have to be improved, particularly for diabetes.

Background

Recent studies have shown the importance of postprandial glucose (PPG) in the development of diabetes complications. This study was conducted in order to survey the perceptions of clinicians and diabetic patients with respect to PPG management and the current status of diabetes education.

Methods

This was a cross-sectional study involving face-to-face interviews and an open questionnaire survey conducted in Korea. A total of 300 patients and 130 clinicians completed questionnaires, which included current education status, self monitoring of blood glucose (SMBG), criteria of diagnosis and management, and perceptions relating to PPG management.

Results

While there was a significantly higher perceived need for diabetes education, the sufficiency of the current education was considered to be severely lacking. Fasting plasma glucose (FPG), PPG, and glycosylated hemoglobin (HbA1c) were all important considerations for clinicians when making a diagnosis of diabetes, although PPG was considered less important than FPG or HbA1c in the treatment of diabetes. Most clinicians and patients were aware of the importance of PPG, but actual education on the importance of PPG was not actively being delivered.

Conclusion

Our study showed that the current status of diabetes education is insufficient to meet the needs of the Korean population. A considerable gap was found to exist between awareness and what was actually taught in the current education program in regard to the importance of PPG. These results suggest that clinicians need to be more active in patient education, especially in regard to the importance of PPG.

Background

The highly developed endoplasmic reticulum (ER) structure in pancreatic beta cells is heavily involved in insulin biosynthesis. Thus, any perturbation in ER function inevitably impacts insulin biosynthesis. Recent studies showed that the expression of tribbles-related protein 3 (TRB3), a mammalian homolog of Drosophilia tribbles, in various cell types is induced by ER stress. Here, we examined whether ER stress induces TRB3 expression in INS-1 cells and found that TRB3 mediates ER stress-induced suppression of insulin gene expression.

Methods

The effects of tunicamycin and thapsigargin on insulin and TRB3 expression in INS-1 cells were measured by Northern and Western blot analysis, respectively. The effects of adenovirus-mediated overexpression of TRB3 on insulin, PDX-1 and MafA gene expression in INS-1 cells were measured by Northern blot analysis. The effect of TRB3 on insulin promoter was measured by transient transfection study with constructs of human insulin promoter.

Results

The treatment of INS-1 cells with tunicamycin and thapsigargin decreased insulin mRNA expression, but increased TRB3 protein expression. Adenovirus-mediated overexpression of TRB3 decreased insulin gene expression in a dose-dependent manner. A transient transfection study showed that TRB3 inhibited insulin promoter activity, suggesting that TRB3 inhibited insulin gene expression at transcriptional level. Adenovirus-mediated overexpression of TRB3 also decreased PDX-1 mRNA expression, but did not influence MafA mRNA expression.

Conclusions

This study showed that ER stress induced TRB3 expression, but decreased both insulin and PDX-1 gene expression in INS-1 cells. Our data suggest that TRB3 plays an important role in ER stress-induced beta cell dysfunction.

A conference was convened by the Korean Diabetes Association and the Korean Endocrine Society on September 7, 2009 to discuss and organize the results of research on intensive glucose control for the prevention of cardiovascular disease in patients with type 2 diabetes. Professor Kyung Soo Park led the conference, and Professors Kwang Won Kim and Ho Young Son acted as chairmen. Professors Doo Man Kim, Tae Sun Park, and Bong Soo Cha reported on intensive glucose control and diabetic complications, including the UK Prospective Diabetes Study (UKPDS), Diabetes Control and Complication Trial (DCCT) research results, the recently published Action to Control Cardiovascular Risk in Diabetes (ACCORD), Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE), and Veterans Affairs Diabetes Trial (VADT) research, as well as meta-analyses. Professor Jeong-Taek Woo reported on the manuscript written by the committee for the Korean Diabetes Association which dealt with the treatment of diabetes mellitus. Professors Kyung Soo Ko, Joong Yeol Park, Hyun Shik Son, Moon-Kyu Lee, Dong-Won Byun, and Yoon-Sok Chung participated in the discussion and collected information for the manuscript from all of the participants. The aim of the debate was to determine how to establish target goals for intensive glucose control and how to individualize those goals. The participants concluded that there was no need to modify the recommendation of maintaining an HbA1c under 6.5%, the current blood glucose treatment goal that is recommended by the Korean Diabetes Association. In addition, individual target goals for glucose control were recommended depending on the situation of each patient. We report on the consensus statement from the meeting.
