Background
To evaluate the safety and effectiveness of empagliflozin in routine clinical settings, we collected and assessed the clinical profiles of Korean patients with type 2 diabetes mellitus.
Methods
This was a post-marketing surveillance study of empagliflozin 10 and 25 mg. Information on adverse events and adverse drug reactions (ADRs) was collected as safety data sets. Available effectiveness outcomes, including glycosylated hemoglobin (HbA1c) level, fasting plasma glucose, body weight, and blood pressure, were assessed.
Results
The incidence rate of ADRs was 5.14% in the safety dataset (n=3,231). Pollakiuria, pruritis genital, and weight loss were the most common ADRs. ADRs of special interest accounted for only 1.18%, and there were no serious events that led to mortality or hospitalization. In the effectiveness data set (n=2,567), empagliflozin significantly reduced the mean HbA1c level and body weight during the study period by –0.68%±1.39% and –1.91±3.37 kg (both P<0.0001), respectively. In addition, shorter disease duration, absence of dyslipidemia, and higher baseline HbA1c levels were identified as the clinical features characteristic of a “responder” to empagliflozin therapy.
Conclusion
Empagliflozin is a safe and potent glucose-lowering drug in routine use among Korean patients with type 2 diabetes mellitus. It is expected to have better glycemic efficacy in Korean patients with poorly controlled type 2 diabetes mellitus.

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

Whether pancreatic steatosis has a local or systemic effect, like ectopic fat of other major organs, remains unknown. Data on the influence of pancreatic steatosis on microvascular complication are rare. Therefore, we investigated the relationship between pancreatic steatosis and diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM).

Methods

The attenuation of three pancreatic regions (head, body, and tail) and the spleen (S) in 186 patients with T2DM was measured using non-enhanced computed tomography imaging. We used three parameters for the assessment of pancreatic steatosis (‘P’ mean: mean attenuation of three pancreatic regions; P–S: difference between ‘P’ mean and ‘S’; P/S: the ‘P’ mean to ‘S’ ratio). The presence of DR was assessed by an expert ophthalmologist using dilated fundoscopy.

Results

The average P mean was 29.02 Hounsfield units (HU), P–S was −18.20 HU, and P/S was 0.61. The three pancreatic steatosis parameters were significantly associated with the prevalence of DR in non-obese T2DM patients. In the non-obese group, the odds ratios of P mean, P–S, and P/S for the prevalence of DR, after adjustment for age, sex, and glycosylated hemoglobin level, were 2.449 (P=0.07), 2.639 (P=0.04), and 2.043 (P=0.02), respectively.

Conclusion

In this study, pancreatic steatosis was significantly associated with DR in non-obese patients with T2DM. Further studies are necessary to clarify the causal relationship between pancreatic steatosis and the development of DR.

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

Diabetes mellitus is a major independent risk factor for cardiovascular disease (CVD), but high cardiovascular risk in diabetes mellitus patients is not completely explained by clustering traditional risk factors. Recently, associations between diabetic polyneuropathy (DPN) and macrovasculopathy have been suggested. We aimed to assess associations between DPN and cardiovascular complications in type 2 diabetic patients.

Methods

Microvascular and cardiovascular complications were evaluated in 1,041 type 2 diabetic patients.

Results

In patients with DPN, the age, prevalence of hypertension, diabetes duration, systolic blood pressure, pulse pressure, and hemoglobin glycation (HbA1c) levels were significantly higher, while the high density lipoprotein cholesterol (HDL-C) levels were lower than in those without DPN. The prevalence of CVD was higher in patients with DPN. In multivariate analysis, DPN was independently associated with CVD (odds ratio, 1.801; 95% confidence interval, 1.009 to 3.214).

Conclusion

Our results showed that DPN was associated with a high prevalence of cardiovascular disease in type 2 diabetic patients, but further studies are needed to investigate the causative nature of associations between DPN and CVD.

Abstract PDF

BACKGROUND
Although the majority of diabetes mellitus (DM) patients diagnosed as adults have non-autoimmune forms of the disease, islet autoimmunity is encountered in some patients initially thought to have type 2 DM. The phenotype of DM patients with glutamic acid decarboxylase (GAD) antibodies is different from that of patients with GAD antibody-negative type 2 DM, with features such as relative leanness and hyperglycemia which may influence the development of complications. We sought to compare the prevalence of chronic complications in patients with and without the GAD antibody. METHODS: We recruited 427 patients (M: 218, F: 209) that were clinically diagnosed with type 2 DM after the age of 35 years. We measured GAD antibody and assessed the factors associated with chronic microvascular and macrovascular complications. RESULTS: Of these patients, 26 were GAD antibody-positive. The patients with GAD antibody had lower systolic blood pressure, higher high-density lipoprotein cholesterol value, and lower level of fasting and stimulated C-peptide than patients without GAD antibody (P < 0.05). Also, the patients with GAD antibody had lower prevalence of retinopathy compared with the patients without GAD antibody (19.2 vs. 47.9%; P < 0.05). The prevalence of nephropathy, peripheral neuropathy and cardiovascular autonomic neuropathy did not differ between the groups. In addition, the prevalence of coronary heart disease, cerebrovascular disease and peripheral arterial disease did not differ between the two groups. CONCLUSION: This study suggests that diabetic patients with GAD antibody have a lower risk for the development of retinopathy compared with patients without GAD antibody.

Abstract PDF: Transient hypoglycemic hemiparesis is a rare but important presentation of hypoglycemia that is frequently misdiagnosed as stroke. The development of hemiparesis as a result of hypoglycemia was first described in 1928. Thereafter over the years, several cases have been sporadically reported in Korea, but case reports of recurrent hypoglycemic hemiparesis are rare. We recently experienced a case of recurrent hypoglycemic hemiparesis in an adult with type 1 diabetes mellitus. A 30-year-old woman with type 1 diabetes receiving daily multiple subcutaneous insulin injections was admitted with right hemiparesis. She had had admitted with the same symptom and recovered with oral carbohydrates in twice 2 years ago. Her clinical course improved over 2 hours after infusion of dextrose solution. Further investigations such as CT, MRI and MRA revealed no abnormality

Abstract PDF: BACKGROUND
Increased platelet aggregability is known to be one of the important risk factors for diabetic vascular complications. The relationship between platelet aggregability and diabetic macrovascular complications, varying severity of diabetic microvascular complications and other possible factors was evaluated in Korean adults. METHODS: Platelet aggregability was measured with platelet rich plasma by addition of adenosine diphosphate (ADP) in 45 cases. Normal control group (n=15) was compared with diabetics without macrovascular complications (n=15), diabetics with macrovascular complications (n=15) and several groups divided accoring to the severity of microvascular complications. RESULTS: 1) The mean maximum value of platelet aggregation was 70.3+/-5.3% in control group, and 80.0+/-7.3% in diabetics (p<0.005). 2) The mean maximum value of platelet aggregation was 78.0+/-5.5% in diabetics without macrovascular complications and 83.5+/-7.1% in diabetics with macrovascular complications (p=0.093). 3) The mean maximum value of platelet aggregation was 77.0+/-5.1% in normoproteinuria group, 78.1+/-7.3% in microproteinuria group, and 82.9+/-6.2% in overt proteinuria group (p=0.083). 4) The mean maximum value of platelet aggregation was 77.2+/-6.8% in diabetes without neuropathy group and 82.9+/-6.2% in diabetes with neuropathy group (p=0.114). 5) The mean maximum value of platelet aggregation was 79.3+/-4.9% in diabetes with normal funduscopic findings, 80.2+/-7.3% in diabetes with background retinopathy and 81.6+/-7.9% in diabetes with proliferative retinopathy (p=0.852). 6) Blood glucose showed positive correlations with the mean maximum platelet aggregation ( =0.529, p<0.005). CONCLUSION: The elevated mean maximum value of platelet aggregation was found in diabetics and there were no significant differences between macrovascular complications and between varying severity of retinopathy, neuropathy and proteinuria. Blood glucose showed positive correlations with mean maximum platelet aggregation. Hyperglycemia was a major risk factor affecting platelet aggregation in diabetics and its control may play an important role in prevention of diabetic vascular complications.

Abstract PDF: BACKGROUND
The risk of atherosclerosis is increased in subjects with diabetes mellitus. Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic vascular disease in subjects without diabetes. The contribution of Lp(a) to the increased risk for atherosclerosis and diabetic complications in subjects with diabetes is not well known. In this report we examined the relationship between Lp(a) levels and development of vascular (macro- and microvascular) complications, and the relationship between Lp(a) and other risk factors for vascular complications in subjects with non-insulin-dependent diabetes mellitus(NIDDM), METHODS: For this study we evaluated 152 patients with NIDDM(72 women and 80 men). Lp(a) level was measured with N-Latex Lp(a) Reagent. Electrocardiography, coronary angiography, brain CT/MRI, doppler velocimetry and peripheral angiography were done for diagnosis of macravascular complieations, and fundus camera, nerve conduction velocity, BBV (beat to beat variation), VPT(vibration perception threshold) and 24-hour urine protein amount were examined for diagnosis of microvascular complications. RESULTS: Lp(a) levels in subjects with ischemic heart disease, cerebrovascular disease and diabetic retinopathy were significantly higher than those in subjects without above mentioned diseases. ApoB/ApoA1 ratio and LDL-cholesterol levels in subjects with Lp(a) level>30mg/dL were significantly higher than those in subjects with Lp(a) level 30mg/dL, and Lp(a) has a positive correlation with ApoB/ApoA1 ratio and LDL-cholesterol in NIDDM patients with vasculopathy. CONCLUSION: These results suggest that high Lp(a) levels seem to be associated with macrovascular and microvascular(especially with retinopathy) complications in subjects with NIDDM and Lp(a) level should be measured in the NIDDM with high level of ApoB/ApoA1 ratio and/or LDL-eholesterol.
