Background
This study investigates the long-term efficacy and safety of evogliptin add-on therapy in patients with inadequately controlled type 2 diabetes mellitus (T2DM) previously received dapagliflozin and metformin (DAPA/MET) combination.
Methods
In this multicenter randomized placebo-controlled phase 3 trial, patients with glycosylated hemoglobin (HbA1c) levels 7.0% to 10.5% (n=283) previously used DAPA 10 mg plus MET (≥1,000 mg) were randomly assigned to the evogliptin 5 mg once daily or placebo group (1:1). The primary endpoint was the difference in the HbA1c level from baseline at week 24, and exploratory endpoints included the efficacy and safety of evogliptin over 52 weeks (trial registration: ClinicalTrials.gov NCT04170998).
Results
Evogliptin add-on to DAPA/MET therapy was superior in HbA1c reduction compared to placebo at weeks 24 and 52 (least square [LS] mean difference, –0.65% and –0.55%; 95% confidence interval [CI], –0.79 to –0.51 and –0.71 to –0.39; P<0.0001). The proportion of patients achieving HbA1c <7% was higher in the triple combination group at week 52 (32.14% vs. 8.51% in placebo; odds ratio, 5.62; P<0.0001). Evogliptin significantly reduced the fasting glucose levels and mean daily glucose levels with improvement in homeostatic model assessment of β-cell function (LS mean difference, 9.04; 95% CI, 1.86 to 16.21; P=0.0138). Adverse events were similar between the groups, and no serious adverse drug reactions were reported in the evogliptin group.
Conclusion
Long-term triple combination with evogliptin added to DAPA/MET showed superior HbA1c reduction and glycemic control compared to placebo at 52 weeks and was well tolerated.

This report presents the status of diabetic neuropathy (DN) in Korea as determined using a National Health Insurance ServiceNational Sample Cohort (NHIS-NSC). Annual prevalences of DN were estimated by age and gender using descriptive statistics. Pharmacological treatments for DN were also analyzed. The annual prevalence of DN increased from 24.9% in 2006 to 26.6% in 2007, and thereafter, gradually subsided to 20.8% in 2015. In most cases, pharmacological treatments involved a single drug, which accounted for 91.6% of total prescriptions in 2015. The most commonly used drugs (in decreasing order) were thioctic acid, an anti-convulsive agent, or a tricyclic antidepressant. In conclusion, the prevalence of DN decreased over the 10-year study period. Thioctic acid monotherapy was usually prescribed for DN. To reduce the socio-economic burden of DN, more attention should be paid to the diagnosis of this condition and to the appropriate management of patients.

Background

Only few studies have shown the efficacy and safety of glucose-control strategies using the quadruple drug combination. Therefore, the aim of the present study was to investigate the usefulness of the quadruple combination therapy with oral hypoglycemic agents (OHAs) in patients with uncontrolled type 2 diabetes mellitus (T2DM).

Methods

From March 2014 to December 2018, data of patients with T2DM, who were treated with quadruple hypoglycemic medications for over 12 months in 11 hospitals in South Korea, were reviewed retrospectively. We compared glycosylated hemoglobin (HbA1c) levels before and 12 months after quadruple treatment with OHAs. The safety, maintenance rate, and therapeutic patterns after failure of the quadruple therapy were also evaluated.

Results

In total, 357 patients were enrolled for quadruple OHA therapy, and the baseline HbA1c level was 9.0%±1.3% (74.9±14.1 mmol/mol). After 12 months, 270 patients (75.6%) adhered to the quadruple therapy and HbA1c was significantly reduced from 8.9%±1.2% to 7.8%±1.3% (mean change, −1.1%±1.2%; P<0.001). The number of patients with HbA1c <7% increased significantly from 5 to 68 (P<0.005). In addition, lipid profiles and liver enzyme levels were also improved whereas no changes in body weight. There was no significant safety issue in patients treated with quadruple OHA therapy.

Conclusion

This study shows the therapeutic efficacy of the quadruple OHA regimen T2DM and demonstrates that it can be an option for the management of T2DM patients who cannot use insulin or reject injectable therapy.

Background

There is limited information regarding the optimal third-line therapy for managing type 2 diabetes mellitus (T2DM) that is inadequately controlled using dual combination therapy. This study assessed the efficacy and safety of pioglitazone or glimepiride when added to metformin plus alogliptin treatment for T2DM.

Methods

This multicenter, randomized, active-controlled trial (ClinicalTrials.gov: NCT02426294) recruited 135 Korean patients with T2DM that was inadequately controlled using metformin plus alogliptin. The patients were then randomized to also receive pioglitazone (15 mg/day) or glimepiride (2 mg/day) for a 26-week period, with dose titration was permitted based on the investigator's judgement.

Results

Glycosylated hemoglobin levels exhibited similar significant decreases in both groups during the treatment period (pioglitazone: −0.81%, P<0.001; glimepiride: −1.05%, P<0.001). However, the pioglitazone-treated group exhibited significantly higher high density lipoprotein cholesterol levels (P<0.001) and significantly lower homeostatic model assessment of insulin resistance values (P<0.001). Relative to pioglitazone, adding glimepiride to metformin plus alogliptin markedly increased the risk of hypoglycemia (pioglitazone: 1/69 cases [1.45%], glimepiride: 14/66 cases [21.21%]; P<0.001).

Conclusion

Among patients with T2DM inadequately controlled using metformin plus alogliptin, the addition of pioglitazone provided comparable glycemic control and various benefits (improvements in lipid profiles, insulin resistance, and hypoglycemia risk) relative to the addition of glimepiride.

Background

Sitagliptin is a highly selective dipeptidyl peptide-4 (DPP-4) inhibitor that increases blood levels of active glucagon-like peptide (GLP)-1 and glucose-dependent insulinotrophic polypeptide (GIP), resulting in increased insulin secretion. While studies conducted in other countries have indicated the efficacy and safety of using sitagliptin to treat type 2 diabetes mellitus (T2DM), its predictors of effects to sitagliptin are not well understood. Therefore, we evaluated the predictive clinical parameters for the therapeutic benefits of sitagliptin when added to an ongoing metformin or sulfonylurea therapy in Korean T2DM subjects.

Methods

We obtained data from 251 Korean T2DM subjects who had recently started taking sitagliptin as add-on therapy. Exclusion criteria included any insulin use. Changes in HbA1c (ΔHbA1c) and fasting plasma glucose (ΔFPG) were assessed by comparing baseline levels prior to sitagliptin administration to levels 12 and 24 weeks after treatment. Responders were defined as subjects who experienced decrease from baseline of >10% in ΔHbA1c or >20% in ΔFPG levels at 24 weeks.

Results

We classified 81% of the subjects (204 out of 251) as responders. The responder group had a lower mean body mass index (23.70±2.40 vs. 26.00±2.26, P≤0.01) and were younger (58.83±11.57 years vs. 62.87±12.09 years, P=0.03) than the non-responder group.

Conclusion

In Korean T2DM subjects, sitagliptin responders had lower body mass index and were younger compared to non-responders.

Background

Inflammation plays a role in the response to metabolic stress in type 2 diabetes. However, the effects of rosiglitazone on inflammation of skeletal muscle have not been fully examined in type 2 diabetes.

Methods

We investigated the effects of the insulin-sensitizing anti-diabetic agent, rosiglitazone, on the progression of skeletal muscle inflammation in Otsuka Long-Evans Tokushima Fatty (OLETF) type 2 diabetic rats. We examined the expression of serologic markers (serum glucose, insulin and free fatty acid) and inflammatory cytokines (tumor-necrosis factor-α, interleukin [IL]-1β and IL-6) in OLETF rats from early to advanced diabetic stage (from 28 to 40 weeks of age).

Results

Serum glucose and insulin concentrations were significantly decreased in rosiglitazone-treated OLETF rats compared to untreated OLETF rats. Rosiglitazone treatment significantly decreased the concentrations of serum inflammatory cytokines from 28 to 40 weeks of age. The mRNA expression of various cytokines in skeletal muscle was reduced in rosiglitazone-treated OLETF rats compared with untreated OLETF rats. Furthermore, rosiglitazone treatment resulted in the downregulation of ERK1/2 phosphorylation and NF-κB expression in the skeletal muscle of OLETF rats.

Conclusion

These results suggest that rosiglitazone may improve insulin sensitivity with its anti-inflammatory effects on skeletal muscle.

AbstractAbstract PDF
BACKGROUND
Streptozotocin-induced diabetic animals are characterized by hyperphagia due to deficiencies of insulin and leptin. Forkhead box-containing protein of the O subfamily-1 (FoxO1) regulates energy homeostasis by regulating energy expenditure and food intake as well as mediating insulin and leptin signals in the hypothalamus. To identify the mediator of diabetic hyperphagia, we examined the effects of insulin or leptin on hypothalamic FoxO1 expression in a diabetic animal model. METHODS: Diabetes was induced in mice (C57BL/6) by intraperitoneal administration of streptozotocin (200 mg/kg). Stainless steel cannula was implanted into the lateral ventricle of the brain in each mouse. After three weeks, the mice were administered saline, insulin or leptin via intracerebroventricular (ICV) route. The medial hypothalamus was isolated to evaluate the mRNA expressions of FoxO1 and neuropeptides. RESULTS: Streptozotocin-induced diabetic mice exhibited significant elevations of blood glucose and food intake and significantly low levels of serum insulin and leptin. The levels of hypothalamic FoxO1 mRNA were significantly increased in diabetic mice. The hypothalamic expression of neuropeptide Y (NPY) mRNA was increased, but the expression of preproopiomelanocortin (POMC) mRNA was decreased in diabetic mice. ICV administration of insulin or leptin attenuated the upregulation of hypothalamic FoxO1 mRNA, and resulted in downregulation of NPY mRNA and upregulation of POMC mRNA in diabetic mice. CONCLUSION: We observed that the expression of hypothalamic FoxO1 mRNA was increased in streptozotocin-induced diabetic mice, and that it was significantly attenuated by central administration of insulin or leptin. These results suggest that hypothalamic FoxO1 is the direct mediator of diabetic hyperphagia.

AbstractAbstract PDF
BACKGROUND
Recent studies suggest that serum Cystatin C is both a sensitive marker for renal dysfunction and a predictive marker for cardiovascular diseases. We aimed to evaluate the association between Cystatin C and various biomarkers and to find out its utility in estimating risk for cardiovascular diseases in type 2 diabetic patients. METHODS: From June 2006 to March 2008, anthropometric measurements and biochemical studies including biomarkers for risk factors of cardiovascular diseases were done in 520 type 2 diabetic patients. A 10-year risk for coronary heart diseases and stroke was estimated using Framingham risk score and UKPDS risk engine. RESULTS: The independent variables showing statistically significant associations with Cystatin C were age (beta = 0.009, P < 0.0001), hemoglobin (beta = -0.038, P = 0.0006), serum creatinine (beta = 0.719, beta < 0.0001), uric acid (beta = 0.048, P = 0.0004), log hsCRP (beta = 0.035, P = 0.0021) and homocysteine (beta = 0.005, P = 0.0228). The levels of microalbuminuria, carotid intima-media thickness, fibrinogen and lipoprotein (a) also correlated with Cystatin C, although the significance was lost after multivariate adjustment. Calculated risk for coronary heart diseases increased in proportion to Cystatin C quartiles: 3.3 +/- 0.4, 6.2 +/- 0.6, 7.6 +/- 0.7, 8.4 +/- 0.7% from Framingham risk score (P < 0.0001); 13.1 +/- 0.9, 21.2 +/- 1.6, 26.1 +/- 1.7, 35.4 +/- 2.0% from UKPDS risk engine (P < 0.0001) (means +/- SE). CONCLUSIONS: Cystatin C is significantly correlated with various emerging biomarkers for cardiovascular diseases. It was also in accordance with the calculated risk for cardiovascular diseases. These findings verify Cystatin C as a valuable and useful marker for predicting future cardiovascular diseases in type 2 diabetic patients.

AbstractAbstract PDF
BACKGROUND
Insulin resistance syndrome (IRS), a clustering of hypertension, impaired glucose tolerance, low HDL cholesterol and high triglyceride, is prevalent in Korea. We studied the correlational structure of IRS using factor analysis to evaluate whether a single process underlies in the clustering of these risk factors. METHODS: Factor analysis was performed using data from 1,018 non-diabetic subjects (388 men and 630 women) who participated in the Jungup epidemiological study. RESULTS: Factor analysis reduced 9 correlated risk factors to 4 independent factors, each reflecting a different aspect of IRS: hypertension factor (increased systolic and diastolic blood pressure), glucose intolerance factor (increased fasting and postload glucose), obesity factor (increased body mass index, waist circumference, and increased insulin), and dyslipidemia factor (increased trigly- cerides and decreased HDL cholesterol). Increased insulin was also loaded into dyslipidemia factor in men and glucose intolerance factor in women. These factors explained about 70% of the total variance in the data. Three factors such as the glucose intolerance factor, the dyslipidemia factor and the obesity factor, were linked through mutual association with hyperinsulinemia, while hypertension factor was not associated with hyperin- sulinemia. Age-adjusted mean BP by BMI tertile and fasting insulin level tertile for men and women increased progressively with increase in BMI in men and women. There was no significant elevation of mean BP according to increase in fasting insulin level. In contrast to premenopausal women in whom hyperinsulinemia show mutual association with the glucose intolerance factor, the dyslipidemia factor, and the obesity factor, hyperinsulinemia was only loaded into obesity factor in postmenopausal women. CONCLUSION: These results suggested that more than one process underlies the clustering of IRS. In sulin resistance alone did not seem to be the single underlying mechanism of IRS. Especially, hypertension was not correlated with hyperin- sulinemia.

AbstractAbstract PDF
BACKGROUND
Glomerular hyperfiltration (GHF) is found in 30-40% of patients with type 1 diabetes at the onset of the disease. Several lines of evidence suggest that this might be responsible for the development of diabetic nephropathy. However, it is still controversial whether GHF is a risk factor in patients with type 2 diabetes. This led us to perform a five-year-prospective study in normoalbuminuric type 2 diabetic patients. METHODS: A total of 68 patients with type 2 diabetes were studied prospectively, They were all normoalbuminuric initially. Glomerular filtration rate was determined by the 51Cr-EDTA single injection method and urinary albumin excretion rate by the radioimtnunoassay method. RESULTS: GHF was present in 19 out of 68 patients. At follow-up, l7 out of 49 patients of the normofiltration group and 3 out of 19 patients of GHF group progressed to microalbuminuria (p>0.05). Multiple logistic regression analysis revealed that the known duration of diabetes, systolic hypertension, and the presence of retinopathy were independently associated with the development of microalbuminuria. CONCLUSION: Our study suggests that GHF does not predict the subsequent development of diabetic nephropathy as indicated by the elevation of the urinary albumin excretion rate during the five year interval.

AbstractAbstract PDF
BACKGROUND
Microalbuminuria is associated with increased cardiovascular mortality in type 2 diabetic patients and non-diabetic subjects. This study was undertaken to determine the prevalence ot microalbuminuria among diabetic and non-diabetic subjects in Korea and to determine the factors associated with microalbuminuria. METHOD: A sample of 1,791 subjects aged > 40 years living in Jungup district were selected from the 28,380 inhabitants using a random cluster sampling method. Among these subjects, 1,006 of them (56.1%) underwent the 75 g oral glucose tolerance test that was also part of the timed overnight urine collection. 46 subjects were excluded because they had signs of urinary tract infection (n=41) or overt proteinuria (n=5). Microalbuminuria was defined as urinary albumin excretion rate (UAER) between 20 and 200 pg/min. RESULTS: Subjects with microalbuminuria had a higher weight and body mass index (BMI), abdominal circumference, systolic and diastolic blood pressure (BP), fasting and 2hr plasma glucose, fasting semm insulin and proinsulin concentrations than subjects without microalbuminuria. The prevalence of micro- albuminuria increased as the glucose tolerance worsened[6.0% in normal glucose tolerance, 11.8% in impaired glucose tolerance (IGT) and 21.8% in diabetes, respectively; x trend=25.9, p<0.(0001]. Mean UAER of subjects with hypertension was greater than that of subjects without hypertension (7.8+0.9ug/min vs. 9.6+0.7ug/min, p<0.001). Univariate analysis revealed that the UAER was significantly (p<0.05) correlated with weight and BMI, abdominal circumference, systolic and diastolic BP, fasting and 2hr plasma glucose, fasting serum insulin and proinsulin after sex-adjustment. Multiple regression analysis revealed that weight or BMI, diastolic BP, 2hr plasma glucose and fasting serum insulin were independently associated with UAER in non-diabetic subjects. CONCLUSION: The present study demonstrates that the prevalence of microalburninuria is higher in patients with glucose intolerance. The association of the UAER with BMI, diastolic BP, 2hr plasma glucose and fasting serum insulin suggest that microalbuminuria is a feature of the insulin resistance syndrome.

AbstractAbstract PDF
BACKGROUND
The clustering of hypertension, impaired glucose tolerance, low HDL cholesteml and high triglyceride is known as insulin resistance syndrome (IRS). We studied the prevalence of insulin resistance syndrome among subjects living in Jungup district, Korea. METHODS: Among a total of 151,000 subjects over 40 years of years living in Jungup district, a sample of 1,791 was selected using a random cluster sampling method. Oral glucose tolerance test revealed 1,018 subjects with normal or impaired glucose tolerance. The IRS was defined as the coexistence of two or more components of triad; hypertension, impaired glucose tolerance and dyslipidemia (triglycerides >= 200mg/dL and HDL <45 mg/dL for woman, HDL < 35 mg/dL for men). RESULTS: Twenty-one percent of men and 45% of women were obese and 50.8% and 61.9% were hypertensive. Eleven percent of men and 16 percent of women were found to have dyslipidemia. The prevalence of impaired glucose tolerance was 10.2% for men and 15.7% for women. The prevalence of IRS in the Jungup population was 12.8% for men and 19.6% for women. The prevalence of IRS increased according to the plasma level of insulin. There was a positive correlation between the number of components of IRS and the level of fasting plasma insulin. CONCLUSION: We conclude that the prevalence of IRS is high in Korean subjects. The close correlation between the IRS components and fasting insulin level suggests that cardiovascular risk is associated with insulin resistance.
