Diabetes mellitus and cognitive dysfunction are highly prevalent in the aging population. In the aging society, clinicians will be increasingly tasked with managing elderly patients who have both cognitive dysfunction and diabetes. A growing number of epidemiological and clinical studies confirmed that diabetes is associated with an increase in the risk of cognitive dysfunction and dementia. Cognitive dysfunction is of particular importance because it is associated with poor self-management ability, poor diabetes management with more frequent severe hypoglycemic episodes, and increased risk of cardiovascular morbidity and mortality. Current diabetes guidelines recommend screening for cognitive dysfunction in older and high-risk patients and providing individualized guidance for patients with cognitive dysfunction. Nonetheless, there is limited awareness among clinicians regarding this subject compared to other diabetic micro- and macrovascular complications. Recently, there has been increasing understanding in this field through multimodal neuroimaging and biomarkers for early detection of cognitive dysfunction in diabetes. In addition, new agents such as glucagon-like peptide 1 receptor agonists showed promising protective effects against cognitive dysfunction and dementia in patients with type 2 diabetes. In this review, we summarize the relationship between diabetes and cognitive dysfunction, especially dementia, and some contributing factors and pathogenesis of dementia in diabetes. We also review how anti-diabetic medications may influence cognitive dysfunction and clinical management guidance.

Two European cohort studies have suggested that Graves’ disease is associated with the development of Parkinson’s disease, although the results were limited and controversial. We evaluated whether patients with Graves’ disease had an increased risk of developing Parkinson’s disease according to treatment modality. We included 65 380 Graves’ disease patients and 326 900 healthy controls matched according to age and sex, using the Korean National Health Insurance database. The primary outcome was the incidences of Parkinson’s disease amongst Graves’ disease patients and controls. Subgroup analyses of Graves’ disease patients were performed according to anti-thyroid drug treatment, radioactive iodine therapy and surgery. The cumulative dose and duration values of anti-thyroid drug were calculated for each patient and categorized into highest, middle and lowest tertiles. Amongst 65 380 Graves’ disease patients, 301 Parkinson’s disease cases were diagnosed during 453 654 person-years of follow-up. Relative to the controls, and regardless of age, sex or comorbidities, the Graves’ disease patients had a 33% higher risk of developing Parkinson’s disease (hazard ratio: 1.33, 95% confidence interval: 1.17–1.51). Most Graves’ disease patients (96%) had received medical therapy, and increased risks of Parkinson’s disease were observed in the various subgroups for cumulative dose and treatment duration. This study revealed that Graves’ disease was an independent risk factor for developing Parkinson’s disease, and that the risk remained elevated regardless of demographic factors or treatment duration/dosage of the anti-thyroid drug. Clinicians should be aware that Graves’ disease patients have an increased risk of developing Parkinson’s disease, even though Graves’ disease patients are often relatively young.

Background Few studies have examined the relationship of sarcopenia with the microcirculation. The current study investigated the relationship of sarcopenia with microcirculatory function, as assessed by skin perfusion pressure (SPP), in type 2 diabetes mellitus (T2DM) patients. Methods In total, 102 T2DM patients who underwent SPP measurements and bioelectrical impedance analysis (BIA) were enrolled in this cross-sectional study. SPP was assessed using the laser Doppler technique. Sarcopenia was defined as low height-adjusted appendicular muscle mass (men, l7 kg/m2; women, l5.7 kg/m2) using BIA. We divided the participants into two groups based on SPP (≤50 and g50 mm Hg), and an SPP below 50 mm Hg was considered to reflect impaired microcirculation. Results Fourteen patients (13.7%) were diagnosed with impaired microcirculatory function of the lower limb based on SPP. The prevalence of sarcopenia in all subjects was 11.8%, but the percentage of patients with an SPP ≤50 mm Hg who had sarcopenia was more than triple that of patients with an SPP g50 mm Hg (28.6% vs. 9.1%, P=0.036). A significant positive correlation was found between SPP and appendicular muscle mass adjusted for height (P=0.041 for right-sided SPP). Multiple logistic regression analysis showed that patients with sarcopenia had an odds ratio of 4.1 (95% confidence interval, 1.01 to 24.9) for having an SPP ≤50 mm Hg even after adjustment for confounding factors. Conclusion These results suggest that sarcopenia may be significantly associated with impaired microcirculation in patients with T2DM. Nonetheless, the small number of patients and wide CI require cautious interpretation of the results.

Background We aimed to examine the associations between the risk of decreased renal function, obesity, and weight changes in Korean type 2 diabetic patients with normal renal function. Methods Type 2 diabetic patients (n = 1060) who visited the diabetic clinic at Soonchunhyang University Bucheon Hospital between 2001 and 2007 with follow up surveys completed in 2016 to 2017 were recruited into the study. Decreased renal function was defined as an estimated glomerular filtration rate 2. Weight change was calculated between baseline and each follow-up survey. Multivariate analysis was used to evaluate the longitudinal association of baseline obesity and weight changes with the risk of decreased renal function. Results This study revealed that baseline obesity was associated with the risk of decreased renal function after adjusting for clinical variables in type 2 diabetic patients (odds ratio [OR] 1.40; 95% confidence intervals [CI] 1.08–2.04; p = 0.025). Follow-up (mean = 12 years) revealed that weight gain > 10% was associated with the risk of decreased renal function after adjusting for clinical variables in type 2 diabetic patients with normal renal function at baseline (OR 1.43; CI 1.11–2.00; p = 0.016). Weight loss was not associated with the risk of decreased renal function in type 2 diabetic patients with normal renal function at baseline. Conclusions Baseline obesity was associated with the increased risk of decreased renal function in Korean type 2 diabetic patients with normal renal function. Weight gain > 10% independently predicted the risk of decreased renal function. Large prospective studies are needed to clarify causal associations between obesity, weight change, and decreased renal function in patients with type 2 diabetes.

Background This study was performed to investigate the association between the amount of alcohol consumption or binge drinking and obesity-related comorbidities in Korean men. Methods A total of 103,048 men aged 19 years or older were investigated in the 2016 Korean Community Health Survey. The participants were divided into five groups according to the standard number of alcoholic drinks consumed per week. Results Of the total participants, 20.7% were in the high alcohol consumption group, consuming more than 28 drinks per week. After adjustment for clinical factors, high alcohol consumption was significantly associated with higher odds ratios (ORs) of obesity (OR, 1.449; 95% confidence interval [CI], 1.412 to 1.591; P P P P = 0.0015) and high alcohol consumption was not associated with a higher risk of diabetes (OR, 0.945; 95% CI, 0.86 to 1.039; P = 0.0662). Among drinkers, except for social drinkers, binge drinking was significantly associated with higher risks of obesity, hypertension, diabetes, and dyslipidemia. Conclusions High alcohol consumption was associated with higher risks of obesity, hypertension, and dyslipidemia in Korean men. In contrast, high consumption was not associated with a higher risk of diabetes. In particular, binge drinkers were associated with higher risks of obesity, hypertension, diabetes, and dyslipidemia compared to non-binge drinkers.

Background: Cardiovascular risk remains increased despite optimal low density lipoprotein cholesterol (LDL-C) level induced by intensive statin therapy. Therefore, recent guidelines recommend non-high density lipoprotein cholesterol (non-HDL-C) as a secondary target for preventing cardiovascular events. The aim of this study was to assess the efficacy and tolerability of omega-3 fatty acids (OM3-FAs) in combination with atorvastatin compared to atorvastatin alone in patients with mixed dyslipidemia. Methods: This randomized, double-blind, placebo-controlled, parallel-group, and phase III multicenter study included adults with fasting triglyceride (TG) levels ≥200 and

The only known, effective intervention for non-alcoholic fatty liver disease (NAFLD) is weight loss, and there is no approved pharmacotherapy. Recently, new hypoglycemic agents, such as sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1RAs), and their effects on NAFLD have received substantial interest. Herein, we review the currently available human studies regarding the effects of SGLT2 inhibitors and GLP-1RAs on NAFLD/non-alcoholic steatohepatitis in patients with type 2 diabetes mellitus, and we describe the possible mechanisms explaining the positive effects of these agents on NAFLD.

Objective:The aim of this study is to investigate the association between glucagon-to-insulin ratio and the presence of nonalcoholic fatty liver disease on ultrasonography in participants with type 2 diabetes mellitus.Research design and methods:This cross-sectional study was performed with data obtained from 172 participants with type 2 diabetes mellitus admitted to a University hospital of Korea. Participants were assessed for serum fasting and postprandial serum glucagon-to-insulin ratio and divided into tertiles. Nonalcoholic fatty liver disease was defined as ultrasonographically detected fatty liver.Results:Prevalence of nonalcoholic fatty liver disease was significantly decreased across tertile of fasting and postprandial glucagon-to-insulin ratio ( p = 0.009 for trend, p = 0.001 for trend, respectively). Lower glucagon-to-insulin ratio was significantly associated with the presence of nonalcoholic fatty liver disease even after adjustment for potential confounding variables [fasting glucagon-to-insulin ratio: odds ratio (95% confidence interval), 2.68 (1.08–6.86)], postprandial glucagon-to-insulin ratio: [2.72 (1.03–7.35)]. The participants in the lowest tertile of fasting glucagon-to-insulin ratio had higher body mass index, visceral fat thickness, subcutaneous fat thickness, homeostasis model assessment–insulin resistance and shorter duration of diabetes mellitus.Conclusion:This study suggests that lower glucagon relative insulin may be independently associated with nonalcoholic fatty liver disease in participants with type 2 diabetes.

Purpose In the present study, the authors investigated the effects of selenium on inflammation, hyaluronan production, and oxidative stress in primary cultured orbital fibroblasts of patients with Graves ophthalmopathy (GO). Methods Orbital adipose/connective tissue specimens were obtained during the course of orbital surgery for patients with GO (n = 7) and other noninflammatory problems (n = 5). After incubation with various concentrations of sodium selenite for 48 hours, supernatants from primary cultures were collected. Hyaluronan and cytokine levels were measured using commercially available enzyme-linked immunosorbent assay kits. To determine the effect of selenium on reactive oxygen species (ROS) production stimulated by H2O2 (100 μM) for 30 minutes, the cells were pretreated with various concentrations of sodium selenite for 60 minutes. Results Interleukin (IL)-6 and tumor necrosis factor-alpha levels were significantly higher in orbital fibroblasts of patients with GO than in orbital fibroblasts of control patients. Hyaluronan production was suppressed by selenium in cultured orbital fibroblasts of patients with GO. Inflammatory cytokines such as IL-1α, IL-8, and tumor necrosis factor-alpha were suppressed by selenium in cultured orbital fibroblasts of patients with GO. IL-1β and IL-6 were not suppressed by selenium in cultured orbital fibroblasts of patients with GO. Selenium pretreatment reduced intracellular ROS generation stimulated by H2O2 in cultured orbital fibroblasts of patients with GO. Conclusions In conclusion, hyaluronan production, inflammatory cytokines, and intracellular ROS generation were suppressed by selenium in cultured orbital fibroblasts of patients with GO. Several inflammatory cytokines may be suppressed by selenium in cultured orbital fibroblasts of patients with GO. This study provide the basis for use of selenium in the treatment of GO.

Background This study aimed to investigate the recent prevalence, management, and comorbidities of diabetes among Korean adults aged ≥30 years by analyzing nationally representative data. Methods This study used data from the Korea National Health and Nutrition Examination Survey from 2016 to 2018, and the percentage and total number of people ≥30 years of age with diabetes and impaired fasting glucose (IFG) were estimated. Results In 2018, 13.8% of Korean adults aged ≥30 years had diabetes, and adults aged ≥65 years showed a prevalence rate of 28%. The prevalence of IFG was 26.9% in adults aged ≥30 years. From 2016 to 2018, 35% of the subjects with diabetes were not aware of their condition. Regarding comorbidities, 53.2% and 61.3% were obese and hypertensive, respectively, and 72% had hypercholesterolemia as defined by low-density lipoprotein cholesterol (LDL-C) ≥100 mg/dL in people with diabetes. Of the subjects with diabetes, 43.7% had both hypertension and hypercholesterolemia. With regard to glycemic control, only 28.3% reached the target level of

Aims Diabetic peripheral neuropathy (DPN) is one of the most common and early manifested complication in T2D. Previous reports have shown that painful sensation of diabetic peripheral neuropathy (DPN) results in sleep problems in type 2 diabetes (T2D)1, 2. However, it is not known that subtype of DPN, the painless DPN also is associated with poor sleep quality in T2D. The purpose of the current study was to investigate the association between painless DPN and poor sleep quality in T2D. Methods A total of 146 patients of T2D who did not previously diagnose with symptomatic DPN were recruited into the study. Among the patients, painless DPN was diagnosed by using the current perception threshold (CPT) test. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Results The percentage of painless DPN was significantly higher in the poor sleep quality group than the good sleep quality group (70.0% vs. 35.5%, P Conclusions The current study showed that painless DPN was associated with poor sleep quality. Future studies are required to clarify the pathophysiologic causal relationship between painless DPN and sleep quality. References 1. Gore M, Brandenburg NA, Dukes E, Hoffman DL, Tai K-S, Stacey B.

We aimed to evaluate the efficacy and safety profile of lobeglitazone compared with sitagliptin as an add-on to metformin in patients with type 2 diabetes as well as other components of metabolic syndrome. Patients inadequately controlled by metformin were randomly assigned to lobeglitazone (0.5 mg, n = 121) or sitagliptin (100 mg, n = 126) for 24 weeks. The mean changes in HbA1c of the lobeglitazone and sitagliptin groups were -0.79% and -0.86%, respectively; the between-group difference was 0.08% (95% confidence interval, -0.14% to 0.30%), showing non-inferiority. The proportion of patients having two or more factors of other metabolic syndrome components decreased to a greater extent in the lobeglitazone group than in the sitagliptin group (-11.9% vs. -4.8%; P < .0174). Favourable changes in the lipid metabolism were also observed with lobeglitazone, which had a similar safety profile to sitagliptin. Lobeglitazone was comparable with sitagliptin as an add-on to metformin in terms of efficacy and safety.

This population-based cross-sectional study aimed to investigate recent trends in the prevalence and treatment of gestational diabetes mellitus (GDM) in Korea. We also investigated trends in annual prevalence rate of pregnancy-induced hypertension (PIH) and cesarean section (C-section) in GDM patients.We used data from the Health Insurance Review and Assessment-National Patient Sample (HIRA-NPS) database, 2012-2016. Non-GDM (n = 53,698) and GDM (n = 7956) patient data were analyzed for each year.The annual increase in the prevalence of GDM was 11.1% over 2012-2016, with a significant continuously increasing trend (p 0.0001). Age-stratified analysis showed that the annual prevalence of GDM significantly increased in patients below 40 years of age, but was not statistically significant as an increasing trend in patients above 40 years of age. Annual PIH prevalence rate among GDM women showed decreasing trend but was not statistically significant. An annual increase in C-section rate above 5% in GDM patients was statistically significant in both unadjusted and adjusted for age and PIH models.The prevalence of GDM in Korean women and C-section rates in women with GDM showed a significantly increasing trend, 2012-2016. There is a need for further efforts to monitor this trend and to identify associated risk factors for GDM in Korean women.

Background Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are expected to improve the liver function of patients with non-alcoholic fatty liver disease (NAFLD) combined type 2 diabetes mellitus (T2DM) by its characteristic mechanism. This study was designed to investigate the effect of dapagliflozin, one of the SGLT2i, on the liver function of T2DM with NAFLD when combined with metformin. Methods Among patients who received dual oral hypoglycemic agents within the 3 months of diagnosing NAFLD, patients who had abnormal alanine aminotransferase (ALT) level (>40 IU/L) were included. Patients were divided into two groups: metformin+dapagliflozin group and metformin+dipeptidyl peptidase-4 inhibitors (DPP4i) group. Demographic data, biochemical data and the clinical and treatment histories of all patients were reviewed. Results A total of 102 patients were included (dapagliflozin group, n=50; DPP4i group, n=52). Dapagliflozin group showed more weight loss and more ALT decline than DPP4i group (-2.9 kg vs. -0.4 kg, P=0.005; -21.1 U/L vs. -9.5 U/L, P=0.008, respectively) and the proportion of patients with ALT normalization after treatment was also significantly higher in the dapagliflozin group (80.0% vs. 61.5%, P=0.041). The effect of dapagliflozin with metformin on ALT normalization remained significant after adjustment for confounding variables including body weight loss (odds ratio, 3.489; P=0.046). Conclusion ALT improvement was statistically significant in the dapagliflozin than the DPP4i when combined with metformin and the result was consistent after adjustment for confounding variables including body weight loss.

Background This report presents the recent prevalence and comorbidities related to diabetes in Korea by analyzing the nationally representative data. Methods Using data from the Korea National Health and Nutrition Examination Survey for 2013 to 2014, the percentages and the total number of subjects over the age of 30 years with diabetes and prediabetes were estimated and applied to the National Population Census in 2014. Diagnosis of diabetes was based on fasting plasma glucose (≥126 mg/dL), current taking of antidiabetic medication, history of previous diabetes, or glycosylated hemoglobin (HbA1c) ≥6.5%. Impaired fasting glucose (IFG) was defined by fasting plasma glucose in the range of 100 to 125 mg/dL among those without diabetes. Results About 4.8 million (13.7%) Korean adults (≥30 years old) had diabetes, and about 8.3 million (24.8%) Korean adults had IFG. However, 29.3% of the subjects with diabetes are not aware of their condition. Of the subjects with diabetes, 48.6% and 54.7% were obese and hypertensive, respectively, and 31.6% had hypercholesterolemia. Although most subjects with diabetes (89.1%) were under medical treatment, and mostly being treated with oral hypoglycemic agents (80.2%), 10.8% have remained untreated. With respect to overall glycemic control, 43.5% reached the target of HbA1c

Background : Vitamin D deficiency is known to increase the incidence of metabolic syndrome. Nonalcoholic fatty liver disease is a common metabolic disease in patients with type 2 diabetes. This study evaluated nonalcoholic fatty liver disease and abdominal fat accumulation according to 25-hydroxyvitamin D status in patients with type 2 diabetes. Methods : The study comprised 302 patients with type 2 diabetes. Patients were divided into three groups based upon their 25-hydroxyvitamin D status: vitamin D deficient group (

Background and aims To evaluate the efficacy and safety of evogliptin, a newly developed dipeptidyl peptidase-4 inhibitor, in patients with type 2 diabetes (T2D) inadequately controlled by diet and exercise. Materials and methods In this randomized, double-blind, placebo-controlled, parallel-group, multicenter, phase III study, 160 patients with T2D were assigned to either an evogliptin 5 mg or placebo group for 24 weeks. The primary endpoint was the mean change in glycated hemoglobin (HbA1c) from baseline to week 24. Results The mean baseline HbA1c levels were similar between the evogliptin and the placebo groups (7.20 ± 0.56 vs. 7.20 ± 0.63%, respectively). At week 24, evogliptin significantly reduced HbA1c levels from baseline compared to placebo (−0.23 vs. 0.05%, respectively, P < .0001). Additionally, the proportion of patients achieving HbA1c < 6.5% was significantly higher in the evogliptin group than that in the placebo group (33.3 vs. 15.2%, respectively, P = .008). The overall incidence of adverse events, including hypoglycemia, was similar between the two groups. Conclusions In this 24-week study, once daily evogliptin monotherapy significantly improved glycemic control and was well tolerated in patients with T2D.

Some clinical manifestations of obesity include nonalcoholic fatty liver disease, type 2 diabetes, and cardiovascular disease. Calorie restriction may aid in weight loss in the short term. Exercise and physical activity are other means of weight loss. However, the efficacy of exercise and physical activity in weight reduction in obese populations is still unknown. In this review, we discuss the effects of exercise and physical activity in obese and overweight populations. We also discuss the effects of aerobic exercise and/or resistance training in weight loss and maintenance.

Aims The aim of this study was to investigate the association between the glycated albumin (GA) to glycated hemoglobin (HbA1c) (GA/HbA1c) ratio and grade of non-alcoholic fatty liver disease (NAFLD) on ultrasonography (US) in patients with type 2 diabetes mellitus (T2DM). Methods This retrospective, cross-sectional study was performed with data obtained from 186 T2DM patients. Participants were assessed for serum GA/HbA1c ratio and fatty liver using US. NAFLD was defined as ultrasonographically detected fatty liver and was graded as normal, mild, moderate, and severe fatty liver. Results A total of 98 subjects (53%) were diagnosed with NAFLD on US, of which 47 (48%) had moderate-to-severe grade of NAFLD. The mean GA level and GA/HbA1c ratio significantly decreased across increasing NAFLD stages (34% vs. 29% vs. 27% vs. 28%, p =0.023 for trend; 3.1vs. 2.9vs. 2.6vs. 2.7, p =0.001 for trend, respectively), whereas there was no significant difference in HbA1c level among groups ( p =0.714 for trend). There was a significant decrease in prevalence of NAFLD across GA/HbA1c ratio tertiles (67% vs. 58% vs. 41%, p for trend=0.007). Multivariate logistic regression analysis showed that individuals with the lowest GA/HbA1c ratio had an odds ratio (OR) of 2.75 (95% CI=1.06–7.13) for having any grade of NAFLD and an OR of 4.48 [1.20–16.74] for moderate-to-severe grade NAFLD compared with the highest GA/HbA1c ratio even after adjustment for confounding factors ( p =0.038, p =0.026, respectively). Conclusion The present study showed that GA/HbA1c ratio was significantly inversely associated with the presence and severity of NAFLD on US.

Aims This trial consisted of a 24-week multicenter, randomised, double-blind, double-dummy, active-controlled study and a 52-week open label extension study to assess the efficacy and safety of evogliptin, a novel dipeptidyl peptidase-4 inhibitor, compared to sitagliptin in patients with type 2 diabetes who have inadequate glycaemic control with metformin alone. Materials and Methods Adult type 2 diabetes mellitus patients (N = 222) with HbA1c 6.5–11% on stable metformin doses (≥1000 mg/day) were randomised 1:1 to add-on 5 mg evogliptin (N = 112) or 100 mg sitagliptin (N = 110) once daily for 24 weeks. The primary efficacy analysis consisted of a comparison of the change from baseline HbA1c at week 24. Non-inferiority was concluded if the upper limit of the two-sided 95% confidence interval for the HbA1c difference between the treatments was

Fine-needle aspiration biopsy (FNAB) cannot distinguish a follicular thyroid carcinoma (FTC) from a follicular adenoma in follicular lesions. We designed this study to determine whether the preoperative thyroglobulin (Tg) and change in serum Tg during thyroid-stimulating hormone (TSH) suppression can predict FTC in thyroid nodules with a cytological diagnosis of follicular lesion.Among 854 patients who underwent thyroid surgery, the 198 patients who presented with thyroid nodules with a cytological diagnosis of follicular lesion were analyzed. Predictive factors for malignancy were evaluated using multivariate logistic regression models. Subgroup analyses of patients with TSH suppression therapy by levothyroxine were also conducted.Thirty-two patients (16%) had FTC, and 166 patients had confirmed benign nodules. The median preoperative serum Tg levels were significantly higher in patients with FTC compared to those with benign pathology (449 vs. 34 ng/mL, p0.001). The serum Tg (odds ratios (OR) 10.311, p0.001) and tumor volume (OR 4.500, p = 0.035) were found to be independent predictors for FTC in all patients with a cytological diagnosis of follicular lesion. Forty-eight patients received TSH suppression therapy. When we performed subgroup analyses on the patients with TSH suppression therapy, decrease less than 15% in serum Tg during TSH suppression was found to be an independent predictor of FTC (OR 13.918, p = 0.018).Preoperative serum Tg and changes in serum Tg during TSH suppression independently predict FTC in thyroid nodules with a cytological diagnosis of follicular lesion.

Sarcopenia is more prevalent in diabetes than controls and is related with higher cardiovascular events such as critical limb ischemia and mortality in T2DM. Microvascular dysfunction in diabetes plays a crucial role in the development of diabetic complications. Skin perfusion pressure (SPP) using laser Doppler technique is valuable in the evaluation of microcirculation function and limb ischemia. Although previous study reported that sarcopenia is independently associated with diabetic foot disease and even it is regarded as a chronic complication of T2DM, no studies have examined the relationship of sarcopenia and microcirculation. The current analysis is an attempt to evaluate the undisclosed relationship of sarcopenia and skin perfusion pressure. We analyzed the data of 188 patients with T2DM performing laser Doppler technique for measuring SPP. Sarcopenia was defined low appendicular muscle mass adjusted for height (Men 50 mmHg. SPP below 50 mmHg was considered as impaired microcirculation. The mean age and SPP of total subjects were 51 years and 72 mmHg. A total of 26 patients (13.8%) were diagnosed with impaired function of microcirculation in limb on SPP. The prevalence of sarcopenia in total subjects was 8%. The prevalence of sarcopenia increased significantly in SPP ≤50 mmHg group than in SPP >50 mmHg (23% vs. 5.3%, p=0.028). Significant positive correlation was found between SPP and appendicular muscle mass adjusted for height (p=0.008). Multiple logistic regression analysis showed that patients with sarcopenia had an odds ratio of 6.1 (95% CI =1.2-31.7) for having of SPP ≤50 mmHg even after adjustment for confounding factors (p=0.032). Our results suggest that the sarcopenia is significantly associated with the presence of impaired function of microcirculation on SPP in T2DM. Disclosure C. Jung: None. D. Choi: None. C. Kim: None.
