A Case of Type 1 Diabetes Mellitus with Diabetic Ketoacidosis Presenting with Transient Severe Fatty Liver and Subsequent Liver Dysfunction.

Patients often present with severe fatty liver (FL) due to insulin deficiency at the onset of diabetic ketoacidosis (DKA). On the other hand, glycogenic hepatopathy (GH) is a possible cause of liver dysfunction in patients with DKA. We herein report a case of type 1 diabetes mellitus with severe FL at the onset of DKA, who demonstrated subsequent marked liver dysfunction after achieving an improvement of FL. As liver dysfunction persisted even after the FL improved, GH was suspected to be the cause of liver dysfunction. FL and GH have different prognoses and should therefore be differentiated using imaging studies and biopsies.

Effectiveness of DialBetesPlus, a self-management support system for diabetic kidney disease: Randomized controlled trial.

We evaluated the effectiveness of a mobile health (mHealth) intervention for diabetic kidney disease patients by conducting a 12-month randomized controlled trial among 126 type 2 diabetes mellitus patients with moderately increased albuminuria (urinary albumin-to-creatinine ratio (UACR): 30-299 mg/g creatinine) recruited from eight clinical sites in Japan. Using a Theory of Planned Behavior (TPB) behavior change theory framework, the intervention provides patients detailed information in order to improve patient control over exercise and dietary behaviors. In addition to standard care, the intervention group received DialBetesPlus, a self-management support system allowing patients to monitor exercise, blood glucose, diet, blood pressure, and body weight via a smartphone application. The primary outcome, change in UACR after 12 months (used as a surrogate measure of renal function), was 28.8% better than the control group's change (P = 0.029). Secondary outcomes also improved in the intervention group, including a 0.32-point better change in HbA1c percentage (P = 0.041). These improvements persisted when models were adjusted to account for the impacts of coadministration of drugs targeting albuminuria (GLP-1 receptor agonists, SGLT-2 inhibitors, ACE inhibitors, and ARBs) (UACR: -32.3% [95% CI: -49.2%, -9.8%] between-group difference in change, P = 0.008). Exploratory multivariate regression analysis suggests that the improvements were primarily due to levels of exercise. This is the first trial to show that a lifestyle intervention via mHealth achieved a clinically-significant improvement in moderately increased albuminuria.

Immediate Impact of Switching from Dipeptidyl Peptidase 4 (DPP4) Inhibitors to Low-Dose (0.3 mg) Liraglutide on Glucose Profiles: A Retrospective Observational Study.

INTRODUCTION: As treatment agents for diabetes, liraglutide is a long-acting glucagon-like peptide 1 receptor agonist, and dipeptidyl peptidase 4 (DPP4) inhibitors are widely used because of their safety and tolerability. Regular treatment with liraglutide has been reported to significantly reduce blood glucose levels, but the impact of low-dose (0.3 mg) liraglutide on blood glucose levels immediately after treatment switching from a DPP4 inhibitor remains unknown. METHODS: We conducted a single-arm, retrospective, observational study in 55 inpatients with type 2 diabetes (T2D) to investigate the changes (Δ) in their blood glucose levels at six time points (6-point) from the day before (day -1) to the day after (day 1) by switching the antidiabetic treatment from a DPP4 inhibitor to liraglutide 0.3 mg (low-dose liraglutide) once daily. We also attempted to identify factors associated with the blood glucose-lowering effects of liraglutide. RESULTS: The median values of the changes in fasting, preprandial, and postprandial blood glucose levels and the fluctuations in the blood glucose levels expressed as the standard deviation of the 6-point blood glucose levels were significantly lower on day 1 than on day -1 (P < 0.05, P < 0.0001, P < 0.0001, P < 0.01, respectively); there were no cases of severe hypoglycemia. The Δ blood glucose levels were not associated with the baseline serum hemoglobin A1c values or with any markers of the insulin secreting capacity. There were no associations between the previously used blood glucose-lowering drug and the Δ blood glucose levels. CONCLUSION: Switching from a DPP4 inhibitor to low-dose (0.3 mg) liraglutide once daily significantly reduced the blood glucose levels and excursions of the blood glucose levels even from the very day after the treatment switch, with no serious adverse events.

Impact of Participant Characteristics on Clinical Outcomes with iGlarLixi in Type 2 Diabetes: Post Hoc Analysis of SPARTA Japan.

INTRODUCTION: The real-world SPARTA Japan study confirmed the effectiveness and safety of the fixed-ratio combination of insulin glargine 100 U/mL plus lixisenatide (iGlarLixi) once daily over 6 months in Japanese people with type 2 diabetes (T2D). This post hoc analysis examined the impact of participant characteristics on the achievement of age-defined glycaemic targets with iGlarLixi therapy. METHODS: The retrospective, observational SPARTA Japan study included adults with T2D who initiated iGlarLixi. In this analysis, data from insulin-naïve and insulin-experienced participants were separately assessed to compare glycated haemoglobin (HbA1c), body weight and safety outcomes between those who achieved ('achieved' group) and those who did not achieve ('not-achieved' group) age-defined glycaemic targets after 6 months of iGlarLixi. The not-achieved group was further stratified by whether or not their iGlarLixi dose was increased during treatment. RESULTS: In total, 418 participants were included in this analysis (138 insulin naïve and 280 insulin experienced). Among both insulin-naïve and insulin-experienced participants, those in the achieved group were older and had lower baseline HbA1c than those in the not-achieved group. Compared with the not-achieved group, the achieved group showed significantly greater HbA1c reductions from baseline (in both insulin-naïve and insulin-experienced participants) and significantly greater body weight reductions (in insulin-naïve participants), despite some participants in the not-achieved group receiving significantly higher insulin glargine doses than those in the achieved group. In both insulin-naïve and insulin-experienced participants, the incidence of hypoglycaemia and gastrointestinal-related adverse events was similar in the achieved and not-achieved groups. In a multivariate analysis, glycaemic target achievement was significantly more likely in older individuals and those who lost weight during iGlarLixi treatment. CONCLUSIONS: Achievement of age-defined glycaemic targets with iGlarLixi treatment for 6 months was significantly affected by increased age and body weight loss, regardless of prior insulin exposure. TRIAL REGISTRATION: UMIN-CTR Trials Registry, UMIN000044126; registered 10 May 2021.

iGlarLixi is an injectable product used to treat type 2 diabetes that contains a fixed combination of two drugs, insulin glargine (at a concentration of 100 U/mL) and lixisenatide. The SPARTA Japan study investigated the effectiveness of controlling blood glucose levels and the safety of iGlarLixi in Japanese people when taken once daily for over 6 months as part of their routine medical care. The analysis reported in this article looked back at data from SPARTA Japan to assess whether certain characteristics of the people who took part in the study affected how well blood glucose targets were met. People who had previously taken insulin and those who had not were identified, and their results were assessed separately. The people were divided into those who had met their blood glucose level target (with the target defined as the glycated haemoglobin level for each person based on their age) and those who had not met their target. It was found that people who achieved their blood glucose target while receiving iGlarLixi were more likely to be older, to have had a lower glycated haemoglobin level before starting iGlarLixi, and to have lost weight during treatment than those who did not achieve their target, whether or not they had previously been treated with insulin. Side effects of excessively low blood glucose levels or gastrointestinal upset with iGlarLixi treatment occurred in a similar number of people who achieved or did not achieve their blood glucose target.

Efficacy of StepAdd, a Personalized mHealth Intervention Based on Social Cognitive Theory to Increase Physical Activity Among Patients With Type 2 Diabetes Mellitus: Protocol for a Randomized Controlled Trial.

BACKGROUND: Increasing physical activity improves glycemic control in patients with type 2 diabetes (T2D). Mobile health (mHealth) interventions have been proven to increase exercise, but engagement often fades with time. As the use of health behavior theory in mHealth design can increase effectiveness, we developed StepAdd, an mHealth intervention based on the constructs of social cognitive theory (SCT). StepAdd improves exercise behavior self-efficacy and self-regulation through the use of goal-setting, barrier-identifying, and barrier-coping strategies, as well as automatic feedback functions. A single-arm pilot study of StepAdd among 33 patients with T2D showed a large increase in step count (mean change of 4714, SD 3638 daily steps or +86.7%), along with strong improvements in BMI (mean change of -0.3 kg/m2) and hemoglobin A1c level (mean change of -0.79 percentage points). OBJECTIVE: In this study, we aim to investigate the efficacy and safety of StepAdd, an mHealth exercise support system for patients with T2D, via a large, long, and controlled follow-up to the pilot study. METHODS: This is a randomized, open-label, multicenter study targeting 160 patients with T2D from 5 institutions in Japan with a 24-week intervention. The intervention group will record daily step counts, body weight, and blood pressure using the SCT-based mobile app, StepAdd, and receive feedback about these measurements. In addition, they will set weekly step count goals, identify personal barriers to walking, and define strategies to overcome these barriers. The control group will record daily step counts, body weight, and blood pressure using a non-SCT-based placebo app. Both groups will receive monthly consultations with a physician who will advise patients regarding lifestyle modifications and use of the app. The 24-week intervention period will be followed by a 12-week observational period to investigate the sustainability of the intervention's effects. The primary outcome is between-group difference in the change in hemoglobin A1c values at 24 weeks. The secondary outcomes include other health measures, measurements of steps, measurements of other behavior changes, and assessments of app use. The trial began in January 2023 and is intended to be completed in December 2025. RESULTS: As of September 5, 2023, we had recruited 44 patients. We expect the trial to be completed by October 8, 2025, with the follow-up observation period being completed by December 31, 2025. CONCLUSIONS: This trial will provide important evidence about the efficacy of an SCT-based mHealth intervention in improving physical activities and glycemic control in patients with T2D. If this study proves the intervention to be effective and safe, it could be a key step toward the integration of mHealth as part of the standard treatment received by patients with T2D in Japan.

Effects of hybrid closed-loop system on glycemic control and psychological aspects in persons with type 1 diabetes treated with sensor-augmented pump: A prospective single-center observational study.

AIMS/INTRODUCTION: This study evaluated the effects of the Medtronic MiniMed 770G hybrid closed-loop system on glycemic control and psychological aspects in persons with type 1 diabetes mellitus. MATERIALS AND METHODS: This 3-month prospective observational study included 22 participants with type 1 diabetes mellitus who used the Medtronic MiniMed 640G predictive low-glucose suspend system and were switched to the 770G system. Time in the range of 70-180 mg/dL and glycated hemoglobin levels were evaluated; satisfaction, emotional distress and quality of life were assessed using self-reported questionnaires, including the Diabetes Treatment Satisfaction Questionnaire Status, Problem Area in Diabetes and Diabetes Therapy-Related Quality of Life. RESULTS: Time in the range of 70-180 mg/dL increased (63.5 ± 13.4 to 73.0 ± 10.9% [mean ± standard deviation], P = 0.0010), and time above the range of 181-250 mg/dL decreased (26.9 ± 8.9 to 19.6 ± 7.1%, P < 0.0005). Glycated hemoglobin levels decreased (7.7 ± 1.0 to 7.2 ± 0.8%, P = 0.0021). The percentage of participants with time below the range of 54-69 mg/dL <4% of readings increased from 91% to 100% (P < 0.0005). No significant changes were detected in the satisfaction, emotional distress and quality of life levels, but increased sensor calibration might be related to worsened emotional distress and quality of life. CONCLUSIONS: The hybrid closed-loop system decreased hyperglycemia and minimized hypoglycemia, but did not improve psychological aspects compared with the predictive low-glucose suspend system, probably because sensor calibration was increased.

Pretreatment body mass index affects achievement of target blood pressure with sodium-glucose cotransporter 2 inhibitors in patients with type 2 diabetes mellitus and chronic kidney disease.

Sodium-glucose cotransporter 2 inhibitor (SGLT2-I) shows excellent antihypertensive effects in addition to its hypoglycemic effects. However, whether body mass index (BMI) affects the antihypertensive effect of SGLT2-I remains unknown. We investigated the impact of baseline BMI on the achievement of target blood pressure (BP) with SGLT2-I treatment in Japanese patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD). We retrospectively evaluated 447 Japanese patients with T2DM and CKD treated with SGLT2-I for at least 1 year. The primary outcome was achieving the target BP (<130/80 mmHg) after SGLT2-I treatment. Patients were divided into two groups according to a baseline BMI of 29.1 determined by receiver operating characteristic analysis and analyzed in a cohort model with propensity score matching. In each group, 130 patients were compared by propensity score matching. The target BP achievement rate was significantly higher in the BMI < 29.1 group than in the BMI ≥ 29.1 group (34% and 21%, respectively, p = 0.03). The odds ratio for achieving the target BP in the BMI ≥ 29.1 group was 0.50 (95% confidence interval, 0.28-0.90, p = 0.02). The BMI < 29.1 group had significantly lower systolic and diastolic BPs after SGLT2-I treatment than the BMI ≥ 29.1 group. Only the BMI < 29.1 group was showed a significant decrease in the logarithmic albumin-to-creatinine ratio from baseline after SGLT2-I treatment. In patients with T2DM and CKD, baseline BMI was associated with the antihypertensive effects of SGLT2-I. Patients in the lower baseline BMI group were more likely to achieve the target BP after SGLT2-I treatment. Pretreatment BMI affects the antihypertensice effect of SGLT2 inhibirors in patients with T2DM and CKD.

Development and Validation of Prediction Models for the 5-year Risk of Type 2 Diabetes in a Japanese Population: Japan Public Health Center-based Prospective (JPHC) Diabetes Study.

BACKGROUND: This study aimed to develop models to predict the 5-year incidence of type 2 diabetes mellitus (T2DM) in a Japanese population and validate them externally in an independent Japanese population. METHODS: Data from 10,986 participants (aged 46-75 years) in the development cohort of the Japan Public Health Center-based Prospective Diabetes Study and 11,345 participants (aged 46-75 years) in the validation cohort of the Japan Epidemiology Collaboration on Occupational Health Study were used to develop and validate the risk scores in logistic regression models. RESULTS: We considered non-invasive (sex, body mass index, family history of diabetes mellitus, and diastolic blood pressure) and invasive (glycated hemoglobin [HbA1c] and fasting plasma glucose [FPG]) predictors to predict the 5-year probability of incident diabetes. The area under the receiver operating characteristic curve was 0.643 for the non-invasive risk model, 0.786 for the invasive risk model with HbA1c but not FPG, and 0.845 for the invasive risk model with HbA1c and FPG. The optimism for the performance of all models was small by internal validation. In the internal-external cross-validation, these models tended to show similar discriminative ability across different areas. The discriminative ability of each model was confirmed using external validation datasets. The invasive risk model with only HbA1c was well-calibrated in the validation cohort. CONCLUSION: Our invasive risk models are expected to discriminate between high- and low-risk individuals with T2DM in a Japanese population.

The concomitant use of sodium-glucose co-transporter 2 inhibitors improved the renal outcome of Japanese patients with type 2 diabetes treated with glucagon-like peptide 1 receptor agonists.

Aims: This study aimed to clarify the renal influence of glucagon-like peptide 1 receptor agonists (GLP1Ras) with or without sodium-glucose co-transporter 2 inhibitors (SGLT2is) on Japanese patients with type 2 diabetes mellitus (T2DM). Methods: We retrospectively extracted 547 patients with T2DM who visited the clinics of members of Kanagawa Physicians Association. The progression of albuminuria status and/or a ≥ 15% decrease in the estimated glomerular filtration rate (eGFR) per year was set as the renal composite outcome. Propensity score matching was performed to compare GLP1Ra-treated patients with and without SGLT2i. Results: After matching, 186 patients in each group were compared. There was no significant difference of the incidence of the renal composite outcomes (17% vs. 20%, P = 0.50); however, the annual decrease in the eGFR was significantly smaller and the decrease in the urine albumin-to-creatinine ratio was larger in GLP1Ra-treated patients with the concomitant use of SGLT2is than in those without it (-1.1 ±â€…5.0 vs. -2.8 ±â€…5.1 mL/min/1.73 m2, P = 0.001; and -0.08 ±â€…0.61 vs. 0.05 ±â€…0.52, P = 0.03, respectively). Conclusion: The concomitant use of SGLT2i with GLP1Ra improved the annual decrease in the eGFR and the urine albumin-to-creatinine ratio in Japanese patients with T2DM.

Proposed carbohydrate antigen 19-9 (CA19-9) cut-off values for the detection of pancreatic cancer in patients with poorly controlled diabetes: a real-world study.

CA19-9 is a tumor marker for pancreatic cancer (PC), and the nondiabetic cut-off level is 37 U/mL. CA19-9 levels are said to rise in patients with tumors like PC and intraductal papillary mucinous neoplasm (IPMN). CA19-9 levels have also been shown to be related to HbA1c levels. We hypothesized that the CA19-9 cut-off levels would differ between patients with poorly controlled diabetes. This real-world trial was designed to test our hypotheses. This was a retrospective cohort study. All inpatients with poorly controlled diabetes had mean HbA1c levels of 10.0% and were divided into three groups: those with pancreatic cancer (PC group, N = 20), those with IPMN (IPMN group, N = 55), and those with neither (NC group, N = 985). Serum CA19-9 levels in the PC group were significantly higher than in the IPMN and NC groups (p < 0.001). CA19-9 levels did not differ statistically between the IPMN and NC groups. According to the receiver operating characteristic (ROC) analysis, serum CA19-9 levels of 98.4 U/mL had the highest sensitivity and specificity to detect PC, when comparing PC to IPMN + NC groups. Using this cut-off, the sensitivity and specificity of CA19-9 for PC were 70.0% and 96.5%, respectively, with a 0.81 area under the ROC curve. CA19-9 levels in two inpatients were >98.4 U/mL, most likely due to hepatocellular carcinoma and esophageal cancer. CA19-9 cut-off levels were thought to be 98.4 U/mL. However, we should keep in mind that the sensitivity and specificity were not 100%.

Hepatic FASN deficiency differentially affects nonalcoholic fatty liver disease and diabetes in mouse obesity models.

Nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes are interacting comorbidities of obesity, and increased hepatic de novo lipogenesis (DNL), driven by hyperinsulinemia and carbohydrate overload, contributes to their pathogenesis. Fatty acid synthase (FASN), a key enzyme of hepatic DNL, is upregulated in association with insulin resistance. However, the therapeutic potential of targeting FASN in hepatocytes for obesity-associated metabolic diseases is unknown. Here, we show that hepatic FASN deficiency differentially affects NAFLD and diabetes depending on the etiology of obesity. Hepatocyte-specific ablation of FASN ameliorated NAFLD and diabetes in melanocortin 4 receptor-deficient mice but not in mice with diet-induced obesity. In leptin-deficient mice, FASN ablation alleviated hepatic steatosis and improved glucose tolerance but exacerbated fed hyperglycemia and liver dysfunction. The beneficial effects of hepatic FASN deficiency on NAFLD and glucose metabolism were associated with suppression of DNL and attenuation of gluconeogenesis and fatty acid oxidation, respectively. The exacerbation of fed hyperglycemia by FASN ablation in leptin-deficient mice appeared attributable to impairment of hepatic glucose uptake triggered by glycogen accumulation and citrate-mediated inhibition of glycolysis. Further investigation of the therapeutic potential of hepatic FASN inhibition for NAFLD and diabetes in humans should thus consider the etiology of obesity.

Impact of glycated hemoglobin on 2-year clinical outcomes in elderly patients with atrial fibrillation: sub-analysis of ANAFIE Registry, a large observational study.

BACKGROUND: This ANAFIE Registry sub-analysis investigated 2-year outcomes and oral anticoagulant (OAC) use stratified by glycated hemoglobin (HbA1c) levels among Japanese patients aged ≥ 75 years with non-valvular atrial fibrillation (NVAF) with and without clinical diagnosis of diabetes mellitus (DM). METHODS: The ANAFIE Registry was a large-scale multicenter, observational study conducted in Japan; this sub-analysis included patients with baseline HbA1c data at baseline. The main endpoints evaluated (stroke/systemic embolic events [SEE], major bleeding, intracranial hemorrhage, cardiovascular death, all-cause death, and net clinical outcome [a composite of stroke/SEE, major bleeding, and all-cause death]) were stratified by HbA1c levels (< 6.0%; 6.0% to < 7.0%; 7.0% to < 8.0%; and ≥ 8.0%). RESULTS: Of 17,526 patients with baseline HbA1c values, 8725 (49.8%) patients had HbA1c < 6.0%, 6700 (38.2%) had 6.0% to < 7.0%, 1548 (8.8%) had 7.0% to < 8.0%, and 553 (3.2%) had ≥ 8.0%. Compared with other subgroups, patients with HbA1c ≥ 8.0% were more likely to have lower renal function, higher CHA2DS2-VASc and HAS-BLED scores, higher prevalence of non-paroxysmal AF, and lower direct OAC (DOAC) administration, but higher warfarin administration. The HbA1c ≥ 8.0% subgroup had higher event rates for all-cause death (log-rank P = 0.003) and net clinical outcome (log-rank P = 0.007). Similar trends were observed for stroke/SEE. In multivariate analysis, risk of all-cause death (adjusted hazard ratio [aHR]: 1.46 [95% confidence interval 1.11-1.93]) and net clinical outcome (aHR 1.33 [1.05-1.68]) were significantly higher in the HbA1c ≥ 8.0% subgroup. No significant differences were observed in risks of major bleeding or other outcomes in this and other subgroups. No interaction was observed between HbA1c and OACs. Use/non-use of antidiabetic drugs was not associated with risk reduction; event risks did not differ with/without injectable antidiabetic drugs. CONCLUSIONS: Among elderly Japanese patients with NVAF, only HbA1c ≥ 8.0% was associated with increased all-cause death and net clinical outcome risks; risks of the events did not increase in other HbA1c subgroups. Relative event risks between patients treated with DOACs and warfarin were not modified by HbA1c level. TRIAL REGISTRATION: UMIN000024006; date of registration: September 12, 2016.

Protective Effects of Imeglimin and Metformin Combination Therapy on ß-Cells in db/db Male Mice.

Imeglimin and metformin act in metabolic organs, including ß-cells, via different mechanisms. In the present study, we investigated the impacts of imeglimin, metformin, or their combination (Imeg + Met) on ß-cells, the liver, and adipose tissues in db/db mice. Imeglimin, metformin, or Imeg + Met treatment had no significant effects on glucose tolerance, insulin sensitivity, respiratory exchange ratio, or locomotor activity in db/db mice. The responsiveness of insulin secretion to glucose was recovered by Imeg + Met treatment. Furthermore, Imeg + Met treatment increased ß-cell mass by enhancing ß-cell proliferation and ameliorating ß-cell apoptosis in db/db mice. Hepatic steatosis, the morphology of adipocytes, adiposity assessed by computed tomography, and the expression of genes related to glucose or lipid metabolism and inflammation in the liver and fat tissues showed no notable differences in db/db mice. Global gene expression analysis of isolated islets indicated that the genes related to regulation of cell population proliferation and negative regulation of cell death were enriched by Imeg + Met treatment in db/db islets. In vitro culture experiments confirmed the protective effects of Imeg + Met against ß-cell apoptosis. The expression of Snai1, Tnfrsf18, Pdcd1, Mmp9, Ccr7, Egr3, and Cxcl12, some of which have been linked to apoptosis, in db/db islets was attenuated by Imeg + Met. Treatment of a ß-cell line with Imeg + Met prevented apoptosis induced by hydrogen peroxide or palmitate. Thus, the combination of imeglimin and metformin is beneficial for the maintenance of ß-cell mass in db/db mice, probably through direct action on ß-cells, suggesting a potential strategy for protecting ß-cells in the treatment of type 2 diabetes.

Predicting three categories of Dementia Assessment Sheet for Community-based Integrated Care System 8-items score-based glycemic targets using the number of animal names recalled.

AIMS/INTRODUCTION: The Dementia Assessment Sheet for Community-based Integrated Care System 8-items (DASC-8) assesses memory, orientation, instrumental activities of daily living and basic activities of daily living. Category I (DASC-8 score ≤10), category II (11 ≤ DASC-8 score ≤16) and category III (DASC-8 score ≥17) have been defined. Based on these categories, the glycemic targets in diabetes patients aged ≥65 years have been proposed by the Japan Diabetes Society and the Japan Geriatrics Society Joint Committee. DASC-8 is difficult to apply to patients without family members or supportive persons. We propose a verbal fluency test as the screening tool. MATERIALS AND METHODS: We enrolled 69 inpatients aged ≥65 years with type 2 diabetes, who were administered the DASC-8 and VF tests, which included recalling animal names and common nouns starting with a specified letter in 1 min. The relationship between DASC-8 and verbal fluency test scores was investigated. RESULTS: Animal fluency correlated with DASC-8 scores after adjustment for patient characteristics. Animal scores correlated with orientation, instrumental activities of daily living and basic activities of daily living scores of DASC-8, and tended to show a relationship with DASC-8 memory scores. An animal score ≥8 predicted category I with a sensitivity of 89% and a specificity of 57%. An animal score ≤6 predicted category III with a sensitivity of 85% and a specificity of 67%. CONCLUSIONS: Animal scores would be useful in predicting the categories of DASC-8. Animal fluency could be a screening tool of DASC-8 when a patient's family member or supportive person is absent.

Endocrinological evaluation of dawn phenomenon in patients with diabetes and comparison of insulin glargine U-100 biosimilar (Insulin Glargine BS Injection "Lilly") and glargine U-300 (Lantus XR): a randomized controlled study.

We investigated the pathophysiology of the dawn phenomenon by examining the effects of changes in blood glucose levels from late night to early morning on various hormones in a group taking glargine BS and a group taking Lantus XR, with the goal of achieving better glycemic control. Patients with types 1 and 2 diabetes scheduled for inpatient education were divided into BS and XR groups. Blood glucose levels were tracked from 0:00 to 7:00, while blood samples were extracted at 3:00 and 7:00 to measure glucose levels and hormones related to the dawn phenomenon. Overall, we analyzed blood sample and intermittently scanned Continuous Glucose Monitoring data of 43 and 40 patients, respectively. From 0:00 to 7:00, the mean blood glucose was significantly lower in the BS group, although the fluctuation was similar (p < 0.0001). The BS group also exhibited significantly higher ∆ACTH (p = 0.0215) and ∆ cortisol (p = 0.0430) than the XR group. In the BS group, ∆Glu exhibited a significant negative correlation with ∆ACTH and ∆cortisol (p = 0.0491). Similar findings were not observed in the XR group. These results suggest that XR may be a better choice for long-acting insulin since it is less likely to induce cortisol secretion. Further, analysis of the dawn phenomenon and non-dawn phenomenon groups showed the mean CPR levels at 3:00 and 7:00 were significantly higher in the latter (p = 0.0135). This supports the conventional belief that appropriate basal insulin replacement therapy is a beneficial treatment for the dawn phenomenon.

A Disproportionality Analysis of the Adverse Effect Profiles of Methimazole and Propylthiouracil in Patients with Hyperthyroidism Using the Japanese Adverse Drug Event Report Database.

Background: Antithyroid drugs (ATDs) are frequently used to achieve euthyroidism in patients with hyperthyroidism. ATDs cause characteristic common and rare adverse events; however, comprehensive comparisons between methimazole (MMI) and propylthiouracil (PTU) in terms of adverse events are limited. Methods: In this study, we thoroughly explored adverse events in association with MMI and PTU use with a disproportionality analysis using the Japanese Adverse Drug Event Report (JADER) database and evaluated the prevalence of MMI and PTU prescriptions using the National Database of Health Insurance Claims and Specific Health Checkups (NDB) Open Data Japan. We analyzed 3271 cases of MMI use and 1029 cases of PTU use with respect to 9789 preferred terms (PTs) for adverse events registered in the JADER database by calculating and comparing reporting odds ratios (RORs). Results: We found that 8 PTs, including agranulocytosis (p < 0.0001, 4.01-fold), aplasia cutis congenita (p < 0.0001, 123.22-fold), and exomphalos (p = 0.0002, 22.17-fold), demonstrated significantly higher RORs (more than 4-fold) for MMI use than for PTU use. Nineteen PTs, including anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (p < 0.0001, 29.84), rapidly progressive glomerulonephritis (p < 0.0001, 6.44), and pulmonary alveolar hemorrhage (p < 0.0001, 7.77), had RORs for PTU use more than four times those for MMI use. NDB Open Data Japan showed more frequent PTU prescriptions than MMI prescriptions for women of reproductive age. Conclusions: This large-scale study confirmed that a variety of congenital malformations were identified as having significantly high RORs for MMI use, while diseases related to ANCA-associated vasculitis were specific to PTU.

Effects of switching from liraglutide to semaglutide or dulaglutide in patients with type 2 diabetes: A randomized controlled trial.

INTRODUCTION: Few studies have examined the effects of glucagon-like peptide-1 receptor agonist switching, particularly in Japanese patients. Therefore, we aimed to investigate the effects of switching from liraglutide to semaglutide or dulaglutide on blood glucose, body weight, and the occurrence of adverse effects in clinical practice. MATERIALS AND METHODS: This was an open-label, prospective, randomized, parallel-group controlled trial. Patients with type 2 diabetes treated with liraglutide (0.6 or 0.9 mg) at Yokosuka Kyosai Hospital in Japan were recruited from September 2020 to March 2022 and, after obtaining informed consent, randomly assigned to the semaglutide or dulaglutide group (1:1). Changes in the glycated hemoglobin level from baseline to weeks 8, 16, and 26 were evaluated post-treatment. RESULTS: Initially, 32 participants were enrolled, of whom 30 completed the study. Glycemic control was significantly better in the semaglutide group than in the dulaglutide group (-0.42 ± 0.49% vs -0.00 ± 0.34%, P = 0.0120). Body weight significantly decreased in the semaglutide group (-2.6 ± 3.6 kg, P = 0.0153), whereas no change was observed in the dulaglutide group (-0.1 ± 2.7 kg, P = 0.8432). We found a significant difference in body weight between the groups (P = 0.0469). The proportion of participants who reported adverse events was 75.0% and 18.8% in the semaglutide and dulaglutide groups, respectively. One patient in the semaglutide group had difficulty continuing treatment due to severe vomiting and weight loss. CONCLUSIONS: Switching from once-daily liraglutide to once-weekly semaglutide 0.5 mg significantly improved glycemic control and body weight compared with switching to once-weekly dulaglutide 0.75 mg.

Sleep duration and food intake in people with type 2 diabetes mellitus and factors affecting confectionery intake.

AIMS/INTRODUCTION: We carried out a cross-sectional study of people with type 2 diabetes mellitus to elucidate the association between sleep duration and food intake. MATERIALS AND METHODS: Overall, 2,887 participants with type 2 diabetes mellitus (mean age 63.0 years; 61.1% men; mean glycated hemoglobin level 7.5%) were included in this study. The participants' self-reported dietary habits and sleep duration were evaluated using a brief self-administered dietary history questionnaire and Pittsburgh Sleep Quality Index, respectively. The participants were categorized into the following four groups based on sleep duration: <6, 6-6.9, 7-7.9 (reference) and ≥8 h. RESULTS: No significant differences were observed between the groups regarding energy intake (kcal/day), absolute intake (g/day) or relative intake (% energy) of carbohydrates, total fat, proteins and fibers. However, confectionery intake was higher in the <6 h group and lower in the ≥8 h group than in the reference group after adjustment for confounding factors. In multivariate analysis, sleep durations <6 h and ≥8 h significantly correlated with increased (95% confidence interval 0.55 to 3.6; P = 0.0078) and decreased (95% confidence interval -4.0 to -0.32; P = 0.021) confectionery intake, respectively. Confectionery intake was positively correlated with female sex, glycated hemoglobin level and dyslipidemia, whereas it was negatively correlated with alcohol consumption and current smoking status. CONCLUSIONS: Short sleep duration is associated with high confectionery intake in people with type 2 diabetes mellitus; this might disturb their glycemic control. Therefore, short sleepers with type 2 diabetes mellitus could improve their glycemic control by avoiding confectionery intake and maintaining adequate sleep duration.

Use of iGlarLixi for the Management of Type 2 Diabetes in Japanese Clinical Practice: Prior Treatment Subgroup Analysis of the SPARTA Japan Study.

INTRODUCTION: iGlarLixi, a fixed-ratio combination of insulin glargine 100 U/mL and the glucagon-like peptide 1 receptor agonist (GLP-1 RA) lixisenatide, is one option for treatment intensification in individuals with type 2 diabetes (T2D) who are unable to achieve targeted glycaemic control with their current glucose-lowering agent. Real-world data on the impact of prior treatment on the effectiveness and safety of iGlarLixi may be useful to guide individualised treatment decisions. METHODS: This analysis of the 6-month, retrospective, observational SPARTA Japan study compared glycated haemoglobin (HbA1c), body weight and safety for pre-specified subgroups defined by prior treatment: post oral antidiabetic agent (OAD), GLP-1 RA, basal insulin (BI) + OADs (BOT), GLP-1 RA + BI or multiple daily injections (MDI). The post BOT and MDI subgroups were further divided on the basis of prior dipeptidyl peptidase 4 inhibitor (DPP-4i) use, and the post MDI group was divided on the basis of whether participants continued bolus insulin. RESULTS: Of the 432 participants in the full analysis set (FAS), 337 were included in this subgroup analysis. Across subgroups, mean baseline HbA1c ranged from 8.49% to 9.18%. iGlarLixi significantly (p < 0.05) reduced mean HbA1c from baseline in all but the post GLP-1 RA + BI group. At 6 months, these significant reductions ranged from 0.47% to 1.27%. Prior DPP-4i exposure had no impact on the HbA1c-lowering effect of iGlarLixi. Mean body weight decreased significantly in the FAS (0.5 kg) and the post BOT (1.2 kg) and MDI (1.5 and 1.9 kg) subgroups but increased in the post GLP-1 RA subgroup (1.3 kg). iGlarLixi treatment was generally well tolerated, with very few participants discontinuing because of hypoglycaemia or gastrointestinal events. CONCLUSION: In participants with suboptimal glycaemic control on various regimens, 6 months of iGlarLixi treatment improved HbA1c in all but one prior treatment subgroup (GLP-1 RA + BI), and was generally well tolerated.

Despite initially receiving oral treatment for their diabetes, many individuals with type 2 diabetes are unable to achieve their blood glucose targets and require treatment intensification as their disease progresses. In these individuals, options for treatment intensification include adding an injectable therapy, such as a glucagon-like peptide 1 receptor agonist or basal insulin, or the combination of both. However, the impact of previously received treatments on the ability of treatment intensification to improve outcomes in these individuals has yet to be evaluated. Here, we report the findings of an analysis that aimed to determine the influence of different treatment backgrounds on the effectiveness and safety of iGlarLixi, a fixed-ratio combination (i.e. combined as a single subcutaneous injection) of the glucagon-like peptide 1 receptor agonist lixisenatide and basal insulin glargine 100 U/mL, in Japanese individuals with type 2 diabetes. We found that iGlarLixi improved glycaemic control and was well tolerated in most individuals, regardless of previously received treatments. These results suggest that iGlarLixi may offer an effective option for improving outcomes in Japanese individuals with type 2 diabetes who require treatment intensification.

Effect of dulaglutide and long-acting insulin combination therapy in patients with type 2 diabetes: a retrospective observational study.

Objective: The study aimed to evaluate the long-term effects of combination therapy comprising dulaglutide and long-acting insulin, on glycemic control in patients with type 2 diabetes. Methods: This retrospective observational study included 20 patients with type 2 diabetes who underwent blood glucose management with intensive insulin therapy for a limited period. All patients were switched from intensive insulin therapy to combination therapy comprising dulaglutide and long-acting insulin. Hemoglobin A1c was evaluated before and 4, 12, and 24 weeks after starting combination therapy. Continuous glucose monitoring was conducted before and 1 and 24 weeks after starting combination therapy. Results: Hemoglobin A1c levels were significantly reduced after 4, 12, and 24 weeks of combination therapy (- 2.2% ± 0.4%, P < 0.0001; - 3.7% ± 0.8%, P = 0.0003; and - 3.6% ± 0.8%, P = 0.0005, respectively). Glycemic variability (% coefficient of variation) was significantly decreased after 1 and 24 weeks of combination therapy (- 5.7% ± 2.1%, P = 0.011; and - 8.7% ± 2.4%, P = 0.003, respectively) and the percentage of readings and time > 250 mg/dL at 24 weeks was significantly improved (- 2.2% ± 0.8%, P = 0.019). Conclusion: Combination therapy with dulaglutide and long-acting insulin resulted in better blood glucose control than intensive insulin therapy, which persisted for 24 weeks. Combination therapy also reduced blood glucose fluctuations and the number of self-injections needed.
