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.
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.
Insurance reimbursement provisions in South Korea limit osteoporosis medication availability for patients with T-scores exceeding - 2.5. This study aimed to evaluate the financial impact and fracture ...prevention of continuous denosumab therapy until a T-score>-2.0 (Dmab-C strategy), versus discontinuation of denosumab after reaching T-score>-2.5 (Dmab-D strategy) in osteoporosis patients.
A cost-consequence analysis from a Korean healthcare system perspective was performed using a newly developed Markov model. The incidence of vertebral and non-vertebral fracture, fracture-related deaths, drug costs, and fracture-treatment costs were estimated and compared between Dmab-C and Dmab-D strategy over a lifetime in eligible patients aged 55 years.
Base-case analysis revealed that Dmab-C prevented 32.21 vertebral fracture (VF) and 12.43 non-VF events per 100 patients over a lifetime, while reducing 1.29 fracture-related deaths. Lifetime direct healthcare cost saving per patient was KRW 1,354,655 if Dmab-C replaces Dmab-D. When productivity losses were considered, Dmab-C saved KRW 29,025,949 per patient compared to Dmab-D. The additional treatment costs of Dmab-C could be offset by the higher subsequent treatment costs and fracture treatment costs of Dmab-D. The sensitivity analysis showed consistent patterns with results of the base-case analysis.
Continuous treatment using denosumab until osteoporosis patients achieve and maintain a T-score of -2.0 would provide greater clinical and economic benefits in terms of fracture prevention and reduced mortality risks compared to outcomes from discontinuing treatment at a T-score of -2.5 or above. This new treatment strategy would effectively lower the risk of fractures and fracture-related mortality, ultimately leading to lower medical expenses.
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.
This study aimed to assess the effects of hormone replacement therapy (HRT) on bone mineral density (BMD) in young women who underwent allogeneic hematopoietic stem cell transplantation (HSCT).
This ...retrospective cohort included 234 female patients with premature ovarian insufficiency (POI) who underwent allogeneic HSCT between April 2009 and April 2016 at Seoul St. Mary's Hospital in Seoul, Korea. Inclusion criteria included adult patients who were age 40 years or younger at the time of transplantation and were followed for at least 3 years after HSCT.
At the first and second years after HRT, there was a significant increase in the BMD of the lumbar spine of the HRT group (n = 170) compared to that of the non-HRT group (n = 64) (P = .033 and P = .047, respectively). The BMD of the lumbar spine significantly increased from baseline by 4.16 ± 4.39% and 5.42 ± 5.86% after 1 and 2 years of HRT, respectively (P = .037 and P = .021). The BMD of the femoral neck and total hip also showed a significant percentage increase from baseline after 2 years of HRT. These changes were significant even in the presence of graft-versus-host disease or steroid exposure. For HRT that was initiated within 12 months after HSCT, the increase in BMD in the lumbar spine was greatest after 2 years of HRT.
These results support that early and active hormonal therapy might be beneficial for BMD in female HSCT recipients with POI.
Albuminuria is closely associated with diabetic retinopathy (DR), but the precise role of the albumin-to-creatinine ratio (ACR) in screening for DR remains to be determined. This study aimed to ...investigate an ACR threshold for predicting DR in patients with type 2 diabetes. A cross-sectional study was conducted on 1,102 type 2 diabetes patients, aged ≥30 years and recruited from the Korea National Health and Nutrition Examination Survey, 2010-2011. Participants were grouped by stage of DR: mild-to-moderate nonproliferative DR (NPDR), severe NPDR, and proliferative diabetic retinopathy (PDR). An early morning spot urine sample was obtained for ACR measurement. ROC curve analysis revealed that the optimal cut-off value of ACR for predicting DR was 2.26 mg/mmol (20 μg/mg). The prevalence of ACR ≥ 2.26 mg/mmol tended to increase with severity of DR. The risk for DR in patients with ACR ≥ 2.26 mg/mmol was higher than in those with ACR < 2.26 mg/mmol. The risk for severe NPDR and PDR also increased at ACR ≥ 2.26 mg/mmol. Normal-to-mildly increased albuminuria (an ACR of 2.26 mg/mmol) may predict the risk for DR development and progression in patients with type 2 diabetes.
