Aims
To evaluate the effects of initiating sodium‐glucose cotransporter‐2 (SGLT2) inhibitors on cardiorenal outcomes and mortality compared to dipeptidyl peptidase‐4 (DPP‐4) inhibitors as active ...comparators in patients diagnosed with type 2 diabetes with a history of percutaneous coronary intervention (PCI).
Materials and Methods
We used an active‐comparator, new‐user design and nationwide data from the National Health Insurance Service in South Korea from 2014 to 2019. Of the 56 392 patients who underwent PCI, 4610 new SGLT2 inhibitor users were paired 1:1 with DPP‐4 inhibitor users for analysis using propensity‐score matching.
Results
During 13 708.59 person‐years of follow‐up, the initiation of SGLT2 inhibitors, compared with the initiation of DPP‐4 inhibitors, was associated with a significantly lower risk of composite repeat revascularization, myocardial infarction, stroke, heart failure (HF), all‐cause death and end‐stage renal disease (ESRD). The beneficial effects of SGLT2 inhibitor use were consistent with the components of stroke, HF, all‐cause death and ESRD. In the cohort that included health examination data, including anthropometric and metabolic factors, new use of SGLT2 inhibitors was associated with a significantly lower risk of HF (hazard ratio HR 0.574, 95% confidence interval CI 0.36–0.915), all‐cause death (HR 0.731, 95% CI 0.567–0.942), and ESRD (HR 0.076, 95% CI 0.018–0.319). The effects of SGLT2 inhibitor use were consistent regardless of the timing of the previous PCI.
Conclusions
The initiation of SGLT2 inhibitors in patients with type 2 diabetes and a history of PCI was significantly associated with a reduced risk of cardiorenal consequences and mortality, irrespective of time since the last PCI.
Aims
We aimed to investigate weight change in patients with new‐onset type 2 diabetes mellitus and the association of weight loss on diabetes remission in Korean adults.
Materials and Methods
We used ...the health examination database of the Korean National Health Insurance Service. Patients diagnosed with type 2 diabetes mellitus from 2009 to 2012 were enrolled and followed to 2017. The baseline body weight was measured at the health examination closest to the time the patient was enrolled, and the change was calculated by examining the weight measured at the subsequent examination within 2 years. Remission was defined as fasting blood glucose less than 126 mg/dl at two or more consecutive health examinations after stopping medication.
Results
In total, 114, 874 patients with new‐onset type 2 diabetes mellitus were analysed. Of these, 23 156 (20.2%) lost more than 5% of their body weight, and 2429 (2.1%) achieved remission. The adjusted odds ratio for remission in the weight loss group was 2.56 (95% confidence interval 2.35‐2.79) compared with the group with stable body weight. Sensitivity analysis according to the degree of weight change showed that the greater weight loss, the higher the likelihood of remission. In the subgroup analysis, the effects of weight loss on remission were significantly greater in subgroups of age <65 years, male sex and body mass index >25.
Conclusion
Weight loss within the first 2 years of treating type 2 diabetes mellitus was associated with diabetes remission. Physicians should pay more attention to weight management in new‐onset type 2 diabetes mellitus, particularly for young and obese individuals.
Aim
This study aimed to investigate the effects of repeated detection of non‐alcoholic fatty liver disease (NAFLD) on the incidence risk of type 2 diabetes in young adults.
Materials and Methods
In ...this nationwide population‐based observational study using data from the Korean National Health Insurance Service, approximately 1 125 015 young adults aged 20‐39 years who underwent health screening four times between 2009 and 2013 were included. NAFLD was defined as a fatty liver index (FLI) of ≥60. Repeated detection of NAFLD scores was defined as the number of times the participants met the criteria for NAFLD (0‐4). To account for the degree of repeated detection of NAFLD, weighted repeated NAFLD scores were scaled as a sum by assigning points (0 points for FLI <30, 1 point for 30 ≤ FLI < 60, and 2 points for FLI ≥60) ranging from 0 to 8 points.
Results
The multivariable‐adjusted hazard ratios of type 2 diabetes associated with repeated detection of NAFLD scores of 1, 2, 3 and 4 were 2.74 (95% confidence interval 2.57‐2.921), 3.45 (3.221‐3.694), 4.588 (4.303‐4.892) and 6.126 (5.77‐6.504), respectively. The incidence risk of type 2 diabetes increased significantly with repeated detection of the NAFLD score. In the analysis of the weighted repeated NAFLD score, the hazard ratios for the incidence of type 2 diabetes showed a significant continuous positive linear association with increasing scores.
Conclusions
Repeated detection of NAFLD influenced the incidence risk of type 2 diabetes in young adults, and a higher degree of repeated detection of NAFLD was independently associated with the risk of type 2 diabetes in young adults.

Summary
Background
A better way to define obesity is in terms of the percentage of body fat (BF). Subjects with normal weight, but excess BF are vulnerable to cardiovascular diseases.
Objective
To ...evaluate the prevalence and characteristics of subjects having normal weight obesity (NWO) using optimal cut‐offs of the BF percentage reflecting risk factors for cardiovascular disease (CVD) in Korean adults.
Design and setting
The Korea National Health and Nutrition Examination Survey in the Korean population conducted in 2009–2010.
Participants
We surveyed 5313 men and 6904 women aged 20 years or older.
Measurements
We investigated the relations between the BF percentage (measured by dual‐energy X‐ray absorptiometry) and obesity‐related risk factors for CVD (diabetes mellitus, hypertension and dyslipidaemia) in Korean adults. NWO was defined as the combination of a normal body mass index (BMI; 18·5–22·9 kg/m2 in Asian subjects) and BF percentages above the determined cut‐off values.
Results
There were strong and graded associations of increasing BF percentages with the prevalence of CVD risk factors. The first cut‐off values (defined as being overweight) in men and women were 20·6% and 33·4% BF, respectively, and the second cut‐off values (defined as obesity) were 25·7% and 36·0% BF. Thirty‐two per cent of normal weight adults had BF percentages greater than or equal to the overweight or obesity cut‐offs (NWO). Subjects with NWO had a lower appendicular skeletal muscle mass, a more atherogenic lipid profile and greater insulin resistance.
Conclusions
Obesity can be defined as 26% BF or greater in Korean men and 36% BF or greater in Korean women. There was a high prevalence of clustering of cardiometabolic abnormalities among subjects with NWO.
Aims/Introduction
We aimed to investigate whether there are differences in the risk factors or markers for the progression of diabetic retinopathy (DR) and diabetic nephropathy (DN) in type 2 ...diabetes mellitus.
Materials and Methods
We carried out a 3‐year retrospective cohort study of 604 patients with type 2 diabetes mellitus. The outcomes were the progression of DR (worsening of the DR stage) and DN (an estimated glomerular filtration rate decline >12%) at the 3‐year follow up. The mean hemoglobin A1c (HbA1c) level and HbA1c variability (HbA1c‐VAR) were calculated.
Results
The mean HbA1c and HbA1c‐VAR levels were higher in the DR progressors (n = 67) than in the DR non‐progressors (n = 537). The mean HbA1c was a significant predictor for DR progression independent of the duration of diabetes and HbA1c‐VAR levels. The urine albumin‐to‐creatinine ratio at baseline and HbA1c‐VAR levels were higher in the DN progressors (n = 34) than in the DN non‐progressors (n = 570). The triglyceride to high‐density lipoprotein cholesterol ratio at baseline tended to be higher in the DN progressors than in the DN non‐progressors. HbA1c‐VAR levels and the triglyceride‐to‐high‐density lipoprotein cholesterol ratio were significant predictors for DN progression independent of estimated glomerular filtration rate and the urine albumin‐to‐creatinine ratio.
Conclusions
Average glycemia was significantly associated with progression of DR, whereas glycemic variability and dyslipidemia were significantly associated with progression of DN in type 2 diabetes mellitus.
Aim
To determine whether the twice‐daily (BID) regimen is superior to the once‐daily (QD) regimen for managing glycaemic variability by comparing the effects of anagliptin 100 mg BID versus ...sitagliptin 100 mg QD.
Materials and Methods
A double‐blinded, randomized, multicentre study was performed in 89 patients with type 2 diabetes treated with metformin alone (6.5% < HbA1c < 8.5%). Subjects were randomly assigned to anagliptin 100 mg BID or sitagliptin 100 mg QD in a 1:1 ratio for 12 weeks. Continuous glucose monitoring was used to measure the mean amplitude of glycaemic excursion (MAGE) and postprandial time in range (TIR) before and after dipeptidyl peptidase‐4 (DPP‐4) inhibitor treatment to compare glycaemic variability.
Results
The decrease from baseline in MAGE at 12 weeks after DPP‐4 inhibitor treatment was significantly greater in the anagliptin BID group than in the sitagliptin QD group (P < .05); −30.4 ± 25.6 mg/dl (P < .001) in the anagliptin group versus −9.5 ± 38.0 mg/dl (P = .215) in the sitagliptin group. The TIR after dinner increased by 33.0% ± 22.0% (P < .001) in the anagliptin group and by 14.6% ± 28.2% (P = .014) in the sitagliptin group, with a statistically significant difference (P = .009). No statistically significant differences were observed between the groups in the changes in HbA1c and fasting plasma glucose (FPG).
Conclusions
The anagliptin BID regimen for the treatment of type 2 diabetes was superior in blood glucose control after dinner to improve glycaemic variability, as indicated by MAGE and TIR, but was equivalent to the QD regimen in terms of HbA1c and FPG.
Previous studies suggest that dipeptidyl peptidase-4 (DPP-4) inhibitors and sodium glucose cotransporter 2 (SGLT2) inhibitors have different effects on the lipid profile in patients with type 2 ...diabetes. We investigated the effects of DPP-4 inhibitors and SGLT2 inhibitors on the lipid profile in patients with type 2 diabetes.
From January 2013 to December 2015, a total of 228 patients with type 2 diabetes who were receiving a DPP-4 inhibitor or SGLT2 inhibitor as add-on therapy to metformin and/or a sulfonylurea were consecutively enrolled. We compared the effects of DPP-4 inhibitors and SGLT2 inhibitors on the lipid profile at baseline and after 24 weeks of treatment. To compare lipid parameters between the two groups, we used the analysis of covariance (ANCOVA).
A total of 184 patients completed follow-up (mean age: 53.1 ± 6.9 years, mean duration of diabetes: 7.1 ± 5.7 years). From baseline to 24 weeks, HDL-cholesterol (HDL-C) levels were increased by 0.5 (95% CI, -0.9 to 2.0) mg/dl with a DPP-4 inhibitor and by 5.1 (95% CI, 3.0 to 7.1) mg/dl with an SGLT2 inhibitor (p = 0.001). LDL-cholesterol (LDL-C) levels were reduced by 8.4 (95% CI, -14.0 to -2.8) mg/dl with a DPP-4 inhibitor, but increased by 1.3 (95% CI, -5.1 to 7.6) mg/dl with an SGLT2 inhibitor (p = 0.046). There was no significant difference in the mean hemoglobin A1c (8.3 ± 1.1 vs. 8.0 ± 0.9%, p = 0.110) and in the change of total cholesterol (TC) (p = 0.836), triglyceride (TG) (p = 0.867), apolipoprotein A (p = 0.726), apolipoprotein B (p = 0.660), and lipoprotein (a) (p = 0.991) between the DPP-4 inhibitor and the SGLT2 inhibitor.
The SGLT2 inhibitor was associated with a significant increase in HDL-C and LDL-C after 24 weeks of SGLT2 inhibitor treatment in patients with type 2 diabetes compared with those with DPP-4 inhibitor treatment in this study.
This study was conducted by retrospective medical record review.
Cardiovascular autonomic neuropathy (CAN) is a risk factor for cardiovascular disease (CVD) and mortality in patients with type 2 diabetes. This study evaluated the relationship between CAN and ...recurrent CVD in type 2 diabetes. A total of 206 patients with type 2 diabetes who had a history of CVD within 3 years of enrollment were consecutively recruited from January 2001 to December 2009 and followed-up until December 2015. Cardiovascular autonomic function tests were performed using the following heart rate variability parameters: expiration-to-inspiration ratio, response to Valsalva maneuver and standing. We estimated the recurrence of CVD events during the follow-up period. A total of 159 (77.2%) of the 206 patients enrolled completed the follow up, and 78 (49.1%) patients had recurrent episodes of CVD, with an incidence rate of 75.6 per 1,000 patient-years. The mean age and diabetes duration were 62.5 ± 8.7 and 9.2 ± 6.9 years, respectively. Patients who developed recurrent CVD also exhibited hypertension (P = 0.004), diabetic nephropathy (P = 0.012), higher mean systolic blood pressure (P = 0.006), urinary albumin excretion (P = 0.015), and mean triglyceride level (P = 0.035) than did patients without recurrent CVD. Multivariable Cox hazard regression analysis revealed that definite CAN was significantly associated with an increased risk of recurrent CVD (hazard ratio HR 3.03; 95% confidence interval CI 1.39-6.60; P = 0.005). Definite CAN was an independent predictor for recurrent CVD in patients with type 2 diabetes who had a known prior CVD event.
The aim of the present study was to identify a threshold for the cholesterol level at which the risk of cardiovascular disease (CVD) begins to increase in people with type 2 diabetes mellitus (DM).
...Using the Korean National Health Insurance Service database, 2,077,135 people aged ≥ 40 years with type 2 DM who underwent regular health checks between 2009 and 2012 were included. Subjects with previous CVD were excluded. Cox regression analyses were performed to estimate the risk of CVD for each low-density lipoprotein cholesterol (LDL-C) group using the < 70 mg/dL as the reference group.
There were 78,560 cases of stroke (3.91%), and 50,791 myocardial infarction (MI, 2.53%) during a median follow-up of 7.1 years. Among participants not taking statins, LDL-C levels of 130-159 mg/dL and ≥ 160 mg/dL were significantly associated with the risk of MI: the hazard ratios (HRs) (95% confidence interval) were 1.19 (1.14-1.25) and 1.53 (1.46-1.62), respectively. Among participants taking statins, all categories of LDL-C level ≥ 70 mg/dL were significantly associated with increased risk of stroke and MI.
We identified an increased risk of CVD in people with an LDL-C level ≥ 130 mg/dL among individuals with type 2 DM not taking statins. The risk of CVD was significantly higher in those taking statins with an LDL-C level ≥ 70 mg/dL.
Abstract Background The hemoglobin glycation index (HGI) is an index of differences in the glycation of hemoglobin according to blood glucose level. The glycation gap (G-gap) is an empiric measure of ...the extent of disagreement between hemoglobin A1C (HbA1C) and glycated albumin (GA). The aim of this study was to investigate the extent of agreement between the HGI and G-gap with respect to GA level, and to elucidate factors related to a high HGI. Method Data were obtained from 105 patients with type 2 diabetes, and fasting blood glucose (FBG), HbA1c, and GA values were measured simultaneously. The G-gap was calculated as the difference between the measured and GA-based predicted HbA1c levels. HGI was calculated as the difference between measured and FBG-based predicted HbA1c levels. Results The HGI and G-gap were highly correlated according GA (r = 0.722, P < 0.001). In general, the two indices were similar in terms of both direction and magnitude. The classification of patients as high, moderate, or low glycators based on HGI versus G-gap was consistent for the majority of the population and only 5% of patients were reclassified from high to low or low to high. Fasting C-peptide levels decreased linearly, and the percentage of patients using insulin increased linearly, between the lowest and highest HGI tertile (both P < 0.05). Conclusions There was 95% agreement between the HGI and G-gap using GA among type 2 diabetes patients. Furthermore, a high HGI was associated with a higher prevalence of insulin use among type 2 diabetes patients.
