Impacts of medication adherence and home healthcare on the associations between polypharmacy and the risk of severe hypoglycemia among elderly diabetic patients in Taiwan from 2002 to 2012: A nationwide case-crossover study. Geriatr Nurs 2024; 58:8-14. [PMID: 38729064 DOI: 10.1016/j.gerinurse.2024.04.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 04/12/2024] [Accepted: 04/19/2024] [Indexed: 05/12/2024]
Abstract
AIM To assess how medication adherence and home healthcare support influence the role of polypharmacy in induced hypoglycemia events among elderly diabetic patients. METHODS This case-crossover study retrieved records on diabetic patients >=65 years with severe hypoglycemia from 2002 to 2012 in Taiwan. Case period defined as 1-3 days before severe hypoglycemia was compared with a preceding control period of the same length, with an all-washout period of 30 days. Moreover, the modifiable effects of medication adherence and home healthcare service use were evaluated by stratified analysis. RESULTS Totally 2,237 patients were identified. Polypharmacy use was associated with the risk of severe hypoglycemia. Patients receiving polypharmacy without home healthcare services (aOR: 1.34; 95 % CI: 1.16-1.54) and those with poor adherence to anti-diabetic medications (aOR: 1.48; 95 % CI: 1.24-1.77) were significantly associated with an elevated risk of severe hypoglycemia. In patients with good adherence, non-home healthcare users being prescribed with polypharmacy had a higher risk of severe hypoglycemia. In the group that received home healthcare services, patients with poor adherence using polypharmacy had a higher risk of severe hypoglycemia. CONCLUSIONS Good adherence and receiving home healthcare services were associated with a decreased odds of severe hypoglycemic events in elderly diabetic patients, regardless of the fact whether they were prescribed with polypharmacy.

Abstract
INTRODUCTION This study aimed to understand the actual status of multimorbidity and polypharmacy among patients with type 2 diabetes using glucose-lowering drugs, and to assess the effects of patient characteristics on severe hypoglycemia and glycemic control. METHODS We designed a retrospective cohort study using health insurance claims and medical checkup data in Japan from April 2016 to February 2021 and identified patients with type 2 diabetes who were prescribed glucose-lowering drugs. We analyzed data on patient characteristics, including multimorbidity and polypharmacy, calculated the incidence rate for severe hypoglycemic events, applied a negative binomial regression model to explore factors that affected severe hypoglycemia, and analyzed the status of glycemic control in the subcohort for which HbA1c data were available. RESULTS Within the analysis population (n = 93,801), multimorbidity was present in 85.5% and mean ± standard deviation for oral drug prescriptions was 5.6 ± 3.5 per patient, while for those aged 75 years or older these numbers increased to 96.3% and 7.1 ± 3.5, respectively. The crude incidence rate for severe hypoglycemia was 5.85 (95% confidence interval 5.37, 6.37) per 1000 person-years. Risk factors for severe hypoglycemia included younger and older age, prior severe hypoglycemia, use of insulin, sulfonylurea, two-drug therapy including sulfonylurea or glinides, three-or-more-drug therapy, excessive polypharmacy, and comorbidities including end-stage renal disease (ESRD) requiring dialysis. Subcohort analysis (n = 26,746) showed that glycemic control is not always maintained according to guidelines. CONCLUSION Patients with type 2 diabetes, particularly older patients, experienced high multimorbidity and polypharmacy. Several risk factors for severe hypoglycemia were identified, most notably younger age, ESRD, history of severe hypoglycemia, and insulin therapy.

Abstract
INTRODUCTION Hypoglycemia is listed as an adverse effect in the package inserts of not only hypoglycemic agents but also many other drugs. We aimed to clarify real-world factors related to an increased risk of hypoglycemia-related hospitalization (HRH) in Japanese patients with type 2 diabetes (T2D) on non-hypoglycemic agents that have been associated with hypoglycemia. RESEARCH DESIGN AND METHODS This cross-sectional study was performed using data from the Medical Data Vision administrative claims database. We identified patients with T2D who were enrolled in the database between April 2014 and October 2019. Logistic regression analyses were performed to identify clinical factors associated with HRH due to non-hypoglycemic agents. RESULTS Among 703 745 patients with T2D, 10 376 patients (1.47%) experienced HRH. The use of 332 non-hypoglycemic agents was associated with hypoglycemia. Multivariate analysis was performed to calculate OR for HRH. Seventy-five drugs had an OR greater than 1, and the values were significant. The OR was the highest for diazoxide (OR 15.5, 95% CI 4.87 to 49.3). The OR was higher than 2.0 for methylphenidate (OR 5.15, 95% CI 1.53 to 17.3), disulfiram (OR 4.21, 95% CI 2.05 to 8.62) and hydrocortisone (OR 2.89, 95% CI 1.11 to 7.51). CONCLUSION This large retrospective analysis revealed that the risk of HRH from some non-hypoglycemic agents in patients with T2D may be increased. The results of this study are expected to support treatment planning by physicians and healthcare professionals involved in diabetes care.

Abstract
BACKGROUND A pharmacist-led, individualised, educational intervention (SUGAR) was formulated to prevent hypoglycaemia among elderly patients with type 2 diabetes mellitus (T2DM) in Jordan. OBJECTIVE(S) To evaluate the effectiveness of the SUGAR intervention added to usual care compared with usual care only in preventing hypoglycaemic attacks in elderly patients with T2DM in Jordan. METHODS A single-centre, pragmatic, open-label, randomised controlled trial with embedded process evaluation was conducted at the outpatient clinics of a hospital in Jordan. Elderly patients (≥65 years) with T2DM and on sulfonylurea, insulin, or at least three anti-diabetic medications were recruited and parallelly randomised to the SUGAR intervention with usual care or the control (usual care) groups. The primary outcome was the rate of total hypoglycaemic attacks per patient after 3 months from randomisation. Secondary outcomes included rate of hypoglycaemia subtypes, the incidence of any and subtypes of hypoglycaemia, hypoglycaemia-free survival probability, and incidence of fasting hyperglycaemia necessitating therapy modification. Outcomes were measured through glucose meters and diaries, assessed at 3 months, and analysed by intention to treat. RESULTS A total of 212 participants (mean age 68.98 years, 58.96% men) were randomly allocated (106 in each group), with 190 (89.62%) participants completing the study. The mean of total hypoglycaemic attacks was less in the intervention group compared with the control group (3.91 [SD 7.65] vs. 6.87 [SD 11.99]; p < 0.0001) at three months. The intervention significantly reduced the rate of hypoglycaemia subtypes; the odds to experience any, severe, and symptomatic hypoglycaemia; and increased hypoglycaemia-free survival probability compared with the control group at three months. Incidence of fasting hyperglycaemia necessitating therapy modification was similar between groups. CONCLUSIONS The SUGAR intervention can prevent hypoglycaemia without increasing the risk of fasting hyperglycaemia warranting therapy adjustment in elderly Jordanians with T2DM.

Abstract
Background Diabetes is a major public health concern with a considerable impact on healthcare expenditures. Deciding on health insurance coverage for new drugs that meet patient needs is a challenge facing policymakers. Our study aimed to assess patients’ preferences for public health insurance coverage of new anti-diabetic drugs in China. Methods We identified six attributes of new anti-diabetic drugs and used the Bayesian-efficient design to generate choice sets for a discrete choice experiment (DCE). The DCE was conducted in consecutive samples of type 2 diabetes patients in Jiangsu Province. The mixed logit regression model was applied to estimate patient-reported preferences for each attribute. The interaction model was used to investigate preference heterogeneity. Results Data from 639 patients were available for analysis. On average, the most valued attribute was the improvement in health-related quality of life (HRQoL) (β = 1.383, p < 0.001), followed by positive effects on extending life years (β = 0.787, p < 0.001), and well-controlled glycated haemoglobin (β = 0.724, p < 0.001). The out-of-pocket cost was a negative predictor of their preferences (β = -0.138, p < 0.001). Elderly patients showed stronger preferences for drugs with a lower incidence of serious side effects (p < 0.01) and less out-of-pocket costs (p < 0.01). Patients with diabetes complications favored more in the length of extended life (p < 0.01), improvement in HRQoL (p < 0.05), and less out-of-pocket costs (p < 0.001). Conclusion The new anti-diabetic drugs with significant clinical effectiveness and long-term health benefits should become the priority for public health insurance. The findings also highlight the value of accounting for preference heterogeneity in insurance policy-making.

Abstract
AIMS/INTRODUCTION Strict management of glucose levels in elderly people with diabetes or with comorbidities exposes them to the risk of severe hypoglycaemia (capillary or venous glucose ≤3.3 mmol/L) and the associated morbidity and mortality. We aimed to describe the clinical, laboratory, and epidemiological characteristics of people with diabetes admitted to the Emergency Department in Cayenne, French Guiana for severe hypoglycaemia and identify avoidable behaviours in this population. MATERIALS AND METHODS An observational epidemiological study of adults with diabetes who presented to the Emergency Department with severe hypoglycaemia was conducted between 2015 and 2018. Their medical history, clinical and laboratory data were collected. The primary outcome was the association between therapeutic misuse and age ≥65 years. RESULTS Overall, 178 admissions were analysed. The main cause of hypoglycaemia was insulin dosing-error or inappropriate glycaemic targets. Among those ≥65 years, 59% had a glycated haemoglobin ≤48 mmol/mol (6.5%), and the median duration of their diabetes was 20 years. Among them, 60% were treated with sulfonylurea, repaglinide, biphasic insulin, or mixed drugs, and 48% were on non-diabetes related treatments that had a hypoglycaemic effect. Furthermore, 23% of the elderly treated with oral antidiabetics had chronic kidney disease. CONCLUSION Many avoidable risk factors for severe hypoglycaemia have been highlighted, in particular insulin dosing errors or non-compliance with recommendations for participants ≥ 65 years. Primary care physicians and homecare nurses need to provide preventive interventions and undergo training.

Abstract
BACKGROUND Self-management of blood glucose levels to avoid hypoglycemia is vital for patients with type 2 diabetes mellitus (T2DM). The association between specific metrics of glycemic variability (glycosylated hemoglobin A1c [HbA1c] and fasting plasma glucose [FPG]) and severe hypoglycemia has not been fully studied in patients with T2DM. METHODS In this post hoc analysis, patients with established T2DM with a high risk of cardiovascular disease were included in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study. The Cox proportional hazards model was used to investigate the relationship between glycemic variability and hypoglycemia requiring medical assistance (HMA) and hypoglycemia requiring any third-party assistance (HAA). The prognostic value of HbA1c/FPG variability for our predefined outcomes was compared using Harrell's C method. RESULTS After adjusting for confounders, each increase in HbA1c variability of 1 standard deviation (SD) indicated a higher risk of HAA (hazard ratio [HR]: 1.10; 95% confidence interval [CI]: 1.03-1.16; P < 0.01) and HMA events (HR: 1.11; 95% CI: 1.03-1.20; P < 0.01). Meanwhile, each increase in FPG variability of 1 SD increased the risk of HAA (HR: 1.40; 95% CI: 1.31-1.49; P < 0.01) and HMA events (HR: 1.46; 95% CI: 1.35-1.57; P < 0.01). Meanwhile, models, including FPG variability, had better prognostic value for our predefined outcomes than HbA1c variability (P < 0.01). CONCLUSIONS Increased visit-to-visit variability in HbA1c and fasting glycemia is associated with a greater risk of severe hypoglycemic events in T2DM patients. FPG variability is a more sensitive indicator than HbA1c variability. TRIAL REGISTRATION http://www.clinicaltrials.gov. Unique identifier: NCT00000620.

Abstract
BackgroundValidation studies on diabetes definitions using nationwide healthcare databases are scarce. We evaluated the validity of diabetes definitions using disease codes and antidiabetic drug prescriptions in the Japanese Diagnosis Procedure Combination (DPC) data via medical chart review.MethodsWe randomly selected 500 records among 15,334 patients who participated in the Japan Public Health Center-Based Prospective Study for the Next Generation in Yokote City and who had visited a general hospital in Akita between October 2011 and August 2018. Of the 500 patients, 98 were linked to DPC data; however, only 72 had sufficient information in the medical chart. Gold standard confirmation was performed by board-certified diabetologists. DPC-based diabetes definitions were based on the International Classification of Diseases, 10th Revision codes, and antidiabetic prescriptions. Sensitivity, specificity, and the positive and negative predictive values (PPV and NPV, respectively) of DPC-based diabetes definitions were evaluated.ResultsOf 72 patients, 23 were diagnosed with diabetes by chart review; 19 had a diabetes code, and 13 had both a diabetes code and antidiabetic prescriptions. The sensitivity, specificity, PPV, and NPV were 89.5% (95% confidence interval: 66.9-98.7), 96.2% (87.0-99.5), 89.5% (66.9-98.7), and 96.2% (87.0-99.5), respectively, for (i) diabetes codes alone; 89.5% (66.9-98.7), 94.3% (84.3-98.8), 85.0% (62.1-96.8), and 96.2 (86.8-99.5) for (ii) diabetes codes and/or prescriptions; 68.4% (43.4-87.4), 100% (93.3-100), 100% (75.3-100), and 89.8% (79.2-96.2) for (iii) both diabetes codes and prescriptions.ConclusionsOur results suggest that DPC data can accurately identify diabetes among inpatients using (i) diabetes codes alone or (ii) diabetes codes and/or prescriptions.

Abstract
Time in range (TIR) is an index of glycemic control obtained from continuous glucose monitoring (CGM). The aim was to compare the glycemic variability of treatment with sulfonylureas (SUs) in type 2 diabetes mellitus (T2DM) with well-controlled glucose level (TIR > 70%). The study subjects were 123 patients selected T2DM who underwent CGM more than 24 h on admission without changing treatment. The primary endpoint was the difference in glycemic variability, while the secondary endpoint was the difference in time below range < 54 mg/dL; TBR < 54, between the SU (n = 63) and non-SU (n = 60) groups. The standard deviation, percentage coefficient of variation (%CV), and maximum glucose level were higher in the SU group than in the non-SU group, and TBR < 54 was longer in the high-dose SU patients. SU treatment was identified as a significant factor that affected %CV (β: 2.678, p = 0.034). High-dose SU use contributed to prolonged TBR < 54 (β: 0.487, p = 0.028). Our study identified enlarged glycemic variability in sulfonylurea-treated well-controlled T2DM patients and high-dose SU use was associated with TBR < 54. The results highlight the need for careful adjustment of the SU dose, irrespective of glycated hemoglobin level or TIR value.

BACKGROUND We investigated the long-term safety and effectiveness of linagliptin in Japanese type 2 diabetes (T2D) patients starting linagliptin add-on therapy in routine clinical practice. RESEARCH DESIGN AND METHODS This 3-year prospective, observational, post-marketing surveillance (PMS) was conducted in Japanese patients starting linagliptin add-on therapy. The primary outcome was the incidence of adverse drug reactions (ADRs). The secondary outcome was the change from baseline in HbA1c. RESULTS The safety analysis set comprised of 3,372 patients. Mean ± standard deviation (SD) age was 66.5 ± 12.4 years. Most patients (63.2%) received linagliptin in combination with another antidiabetic drug, most commonly a sulfonylurea (38.6%). The incidence of ADRs was 11.39%; the most common ADRs according to MedDRA preferred terms were diabetes mellitus (1.25%), hypertension (0.83%), and hypoglycemia (0.80%). In the effectiveness analysis set (n = 3,029), mean ± SD HbA1c was 7.76 ± 1.37% at baseline and 7.26 ± 1.19% at last observation; mean change from baseline to last observation was - 0.49 ± 1.33%; sustained reductions in HbA1c were observed. These results were consistent across patient subgroups. CONCLUSIONS In this PMS, linagliptin add-on therapy for Japanese T2D patients had a safety profile consistent with its known profile and HbA1c reductions over 3 years were observed.

Abstract
BACKGROUND Previous meta-analysis investigating the incidence and prevalence of hypoglycaemia in both types of diabetes is limited. The purpose of this review is to conduct a systematic review and meta-analysis of the existing literature which investigates the incidence and prevalence of hypoglycaemia in individuals with diabetes. METHODS PubMed, Embase and Cochrane library databases were searched up to October 2018. Observational studies including individuals with diabetes of all ages and reporting incidence and/or prevalence of hypoglycaemia were included. Two reviewers independently screened articles, extracted data and assessed the quality of included studies. Meta-analysis was performed using a random effects model with 95% confidence interval (CI) to estimate the pooled incidence and prevalence of hypoglycaemia in individuals with diabetes. RESULTS Our search strategy generated 35,007 articles, of which 72 studies matched the inclusion criteria and were included in the meta-analysis. The prevalence of hypoglycaemia ranged from 0.074% to 73.0%, comprising a total of 2,462,810 individuals with diabetes. The incidence rate of hypoglycaemia ranged from 0.072 to 42,890 episodes per 1,000 person-years: stratified by type of diabetes, it ranged from 14.5 to 42,890 episodes per 1,000 person-years and from 0.072 to 16,360 episodes per 1,000-person years in type 1 and type 2 diabetes, respectively. CONCLUSION Hypoglycaemia is very common among individuals with diabetes. Further studies are needed to investigate hypoglycaemia-associated risk factors.

Abstract
OBJECTIVES Studies showing that individuals with non-small cell lung cancer (NSCLC) and diabetes mellitus (DM) have reported poor outcomes after pulmonary resection with varying results. Therefore, we investigated the clinical impact of preoperative DM on postoperative morbidity and survival in individuals with resectable NSCLC. PATIENTS AND METHODS Data of individuals who underwent pulmonary resection for NSCLC from 2000 to 2015 were extracted from the database of Kyoto University Hospital. The primary endpoint was the incidence of postoperative complications, and secondary endpoints were postoperative length of hospital stay and overall survival. The survival rate was analyzed using the Kaplan-Meier method. RESULTS A total of 2,219 patients were eligible for the study. The median age of participants was 67 years. Among them, 39.5% were women, and 259 (11.7%) presented with DM. The effect of DM on the incidence of postoperative complications and postoperative length of hospital stay was not significant. Although the 5-year survival rates were similar in both patients with and without DM (80.2% versus 79.4%; p = 0.158), those with DM who had a hemoglobin A1c level ≥ 8.0% had the worst survival. CONCLUSIONS In individuals with resectable NSCLC, preoperative DM does not influence the acute phase postoperative recovery. However, poorly controlled preoperative DM could lead to low postoperative survival rates.

Abstract
AIMS/INTRODUCTION The incidence of severe hypoglycemia and its risk factors including an insulin-sensitizing adipokine, adiponectin, were prospectively investigated in Japanese patients with type 1 or insulin-treated type 2 diabetes. MATERIALS AND METHODS A total of 207 participants with type 1 diabetes (mean age 55 years) and 1,396 with insulin-treated type 2 diabetes (mean age 65 years) from the local diabetes registry were followed for 5 years (follow-up rate 99%). Severe hypoglycemia was defined as events requiring the assistance of others for recovery from hypoglycemia. RESULTS The incidence of severe hypoglycemia was 9.2 per 100 person-years in those with type 1 diabetes, and 2.3 per 100 person-years in those with insulin-treated type 2 diabetes, respectively. For type 1 diabetes, the risk was significant in those with a history of severe hypoglycemia within the previous year, slow eating and higher serum adiponectin (the highest vs the lowest in quartile hazard ratio 2.36, 95% confidence interval 1.22-4.69). For insulin-treated type 2 diabetes, the risk included age ≥65 years, history of severe hypoglycemia within the previous year, alcohol consumption ≥60 g/day, larger insulin dose and higher serum adiponectin (the highest vs the lowest in quartile, hazard ratio 2.95, 95% confidence interval 1.22-4.69). For all participants, the incidence of severe hypoglycemia increased along with serum adiponectin (age- and sex-adjusted hazard ratio 1.65 per 1 standard deviation increase of log serum adiponectin, 95% confidence interval 1.45-1.87). CONCLUSIONS The incidence of severe hypoglycemia was prospectively determined, and the association between severe hypoglycemia and higher serum adiponectin was observed in Japanese patients with type 1 and insulin-treated type 2 diabetes.

Abstract
AIMS Using data from DISCOVER (NCT02322762; NCT02226822), a 3-year, global, observational study programme of patients with type 2 diabetes initiating second-line glucose-lowering therapy, we assessed socioeconomic factors associated with hypoglycaemic events and fear of hypoglycaemia. METHODS Data were collected at baseline (second-line therapy initiation) and 6, 12 and 24 months. Factors associated with experiencing a hypoglycaemic event at baseline or during follow-up were determined using a hierarchical logistic regression model and an interval-censored survival analysis, respectively. Fear of hypoglycaemia was assessed using the hypoglycaemia fear survey-II (HFS-II). RESULTS The overall proportion of patients reporting hypoglycaemic events during follow-up was 7.3%; this was higher in middle-income countries than in high-income countries (8.4% vs 5.8%, p < 0.001). Factors associated with an increased risk of hypoglycaemia during follow-up included living in a country with a low gross national income, use of glucose-monitoring equipment and second-line treatment with insulin, meglitinides or sulphonylureas (versus metformin). Experiencing hypoglycaemia was associated with increased HFS-II worry and overall scores. CONCLUSIONS Our results highlight the global inequity in the treatment of type 2 diabetes. Increased risk of hypoglycaemia in middle-income countries may be explained by limited treatment options and may be underestimated because of limited access to glucose-monitoring equipment.

Abstract
Background Hypoglycemia is a pathological condition in which the serum glucose level measures less than 3.0 mmol/L. It is a well-known complication in patients with diabetes mellitus. Age, body weight, gender, insulin usage, nutritional therapy, body mass index (BMI), the presence of diabetes complications, intensive care unit admission, and infection were reported as possible risk factors that may increase the risk of hypoglycemia. Therefore, this study aimed to analyze predisposing factors for hypoglycemia among hospitalized patients with type 2 diabetes in King Abdulaziz Medical City. Method This is a retrospective, case-control study design. The study included 326 hospitalized patients with type 2 diabetes; 152 experienced hypoglycemia (blood glucose <3.9) at least once during hospitalization and have been compared to 174 in the non-hypoglycemic group (blood glucose ≥3.9). Data were extracted from their electronic medical records (EMRs). Results This study reported that patients with lower BMI (28.80 ± 7 versus 31.20 ± 12.93) experienced hypoglycemia (P-value 0.044). Those hospitalized with infections or had acquired infections or required intensive care unit (ICU) admission during hospitalization had a higher risk to develop hypoglycemia (P-value 0.005, 0.003, and <0.001, respectively). Moreover, the use of multiple doses of insulin therapy or basal-plus insulin therapy was associated with a higher risk of hypoglycemia (P-value 0.012 and 0.028, respectively). Those on supplemental insulin were less likely to develop hypoglycemia (P-value <0.001). Patients on oral feeding had a lower chance of having a hypoglycemic attack (P-value 0.002) while those on tube feeding had double the odds (OR=2.37). Conclusions Infection, intensive care unit admission, lower body mass index, insulin regimen and nutritional therapy (enteral feeding and nothing-per-mouth (NPO)) were correlated with an elevated risk of having hypoglycemia in hospitalized patients with type 2 diabetes mellitus.

Abstract
AIM Our aim was to investigate the effects of add-on canagliflozin with glimepiride dose adjustment or glimepiride dose adjustment on pancreatic beta cell function in patients with type 2 diabetes mellitus and inadequate glycemic control despite stable triple therapy (metformin, teneligliptin, and glimepiride) plus diet/exercise therapy. METHODS Forty patients on stable triple therapy were randomized to glimepiride dose adjustment without (glimepiride group) or with add-on canagliflozin 100 mg (canagliflozin group) for 24 weeks. The glimepiride dose was adjusted every 4 weeks based on continuous glucose monitoring over the previous 2 weeks according to a prespecified algorithm. After the 24-week treatment period, the patients returned to the pre-intervention regimen for 1 week (wash-out period). Patients underwent 75 g OGTTs at the start of the run-in period and at the end of the wash-out period. The primary endpoint was the change in disposition index (DI). RESULTS Thirty-nine patients completed the study (canagliflozin, n = 19; glimepiride, n = 20). The change in DI was +5.1% and -11.0% in the canagliflozin and glimepiride groups, respectively, with a between-group difference ratio of 18.0% (P = 0.330). HbA1c, fasting plasma glucose, body weight, and daily-life continuous glucose monitoring-derived parameters improved in the canagliflozin group. Hypoglycemia occurred in 60% (44 episodes) and 70% (79 episodes) of patients in the canagliflozin and glimepiride groups, respectively. The change in DI was significantly correlated with the changes in glycemic control and variability in overall cohort. CONCLUSION Adding canagliflozin to the triple therapy improved beta cell function by 18%, but it did not reach statistical significance. This study also demonstrated a correlation between the change in DI and glycemic control. As canagliflozin improved both glucose level and variability with relatively lower risk of hypoglycemia compared with glimepiride dose adjustment, adding canagliflozin to the triple therapy may be clinically beneficial.

Abstract
INTRODUCTION Insulin glargine 300 U/ml (U300) was registered based on the EDITION clinical trial program. The aim of this database analysis was to describe the profile of adult U300 recipients with type-1 (T1DM) or type-2 diabetes (T2DM). METHODS The analysis was based on data from the German DIVE/DPV registries. Patients were sampled in May (DIVE) and in March 2018 (DPV) and divided into those who commenced U300 within the 1st year (early adopters) or 2nd year (late adopters). Patients were further compared to patients receiving U100 during the same time period. RESULTS Among 581,519 adult patients contained in the databases, 7268 with either T1 or T2DM received U300 and 22,050 U100. Baseline characteristics of U300 and U100 recipients did not differ substantially in both types of diabetes. Patients with T2DM had many risk factors and comorbidities. The median HbA1c (both T1DM and T2DM, 8.1% for U300 and 7.9 and 8.3% for U100) and fasting blood glucose values were similar at baseline. Severe hypoglycemia was less prevalent in T2DM and among recipients of U300 (3.1 vs. 3.9%), whereas in T1DM the rate was higher (10.6 vs. 10.1%). There were minor, but clinically probably irrelevant, differences in age and BMI for T1DM and T2DM between the first and second years. Patients with T2DM being initiated in the second year had a higher HbA1c value (8.6 vs. 8.3%) than those initiated during the first year. Patients in clinical practice showed substantially higher HbA1c values in both T1DM and T2DM, and doses used were lower than those reported from the EDITION trial program. U300 patients had a longer diabetes duration (T1 and T2DM), a higher BMI and received higher basal insulin doses (T1 and T2DM) compared to U100. While HbA1c was comparable, the rate of severe hypoglycemia under U300 was reduced in T2DM but not T1DM with or without adjustment for differences in baseline characteristics in T2DM. CONCLUSION The data confirm the clinical profile documented for U300 in the EDITION studies during the first years of its registration. In an unselected patient population, there was a lesser rate of severe hypoglycemia but at a comparable HbA1c. FUNDING German Centre for Diabetes Research (DZD) (01GI1106), the European Foundation for the Study of Diabetes (EFSD) and the German Diabetes Society (DDG). The DIVE registry (organized as Diabetes Agenda 2010 GmbH, Berlin, Germany) received funding from Sanofi, AstraZeneca, Bayer, and Abbott and was conducted under the auspices of diabetesDE.

J Diabetes Investig 2019; 10:857-865. [PMID: 30325576 PMCID: PMC6497613 DOI: 10.1111/jdi.12959] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Revised: 10/05/2018] [Accepted: 10/11/2018] [Indexed: 01/05/2023] Open
Abstract
AIMS/INTRODUCTION The present study aimed to describe hospital utilization and examine actual medical costs for severe hypoglycemic events in patients with type 2 diabetes mellitus in Japan. MATERIALS AND METHODS Medical resource utilization associated with severe hypoglycemia was evaluated using a receipt database of acute-care hospitals in Japan. Patients with type 2 diabetes treated with antihyperglycemic agents were included. Severe hypoglycemic events were identified and divided into two groups: with or without hospitalization. Total and attributable medical costs per event were calculated based on the actual medical treatment after severe hypoglycemic events. Attributable costs were estimated from the receipt codes directly associated with the treatment of severe hypoglycemia. RESULTS In the hospitalized patients, the median length of hospital stay was 11 days, and the median total and attributable medical costs were ¥402,081 and ¥302,341, respectively. The majority of the hospitalized patients underwent a radiographic examination and general blood tests. Apart from the hospitalization costs, the costs associated with diagnosis accounted for 29.6% of the total medical costs. In the outpatients, 60.6% visited hospitals only once for the severe hypoglycemic event, whereas 11.4% visited hospitals daily for a week after the severe hypoglycemic event. The mean number of hospital visits of the outpatient after a severe hypoglycemic event was 2.7 ± 2.6 days. The median total and attributable medical costs were ¥265,432 and ¥4,628, respectively. CONCLUSIONS Significant medical resources are used for the treatment of severe hypoglycemic events of patients with type 2 diabetes in Japan.

Diabetes Obes Metab 2019; 21:648-657. [PMID: 30370611 DOI: 10.1111/dom.13568] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2018] [Revised: 10/22/2018] [Accepted: 10/25/2018] [Indexed: 12/12/2022]
Abstract
AIM To determine the incidence of severe hypoglycaemia and its predictors in community-based patients with type 2 diabetes studied between 2008 and 2013 compared with those in a cohort of patients with type 2 diabetes from the same geographical area assessed a decade earlier. METHODS We studied 1551 participants (mean age 65.7 years, 51.9% men) with type 2 diabetes from the longitudinal observational Fremantle Diabetes Study Phase II (FDS2). Severe hypoglycaemia was ascertained as that requiring ambulance attendance, emergency department services and/or hospitalization. Cox proportional hazards modelling was used to determine predictors of a first episode of severe hypoglycaemia, and negative binomial regression was used to identify predictors of frequency. RESULTS Sixty-three participants (4.1%) experienced 83 episodes, representing an incidence of 1.34/100 participant-years (95% confidence interval [CI] 1.08 to 1.67; vs 1.67/100 participant-years [95% CI 1.31-2.13] in the Fremantle Diabetes Study Phase I [FDS1]; P = 0.18). Those experiencing severe hypoglycaemia experienced one to four episodes in both cohorts. The independent predictors of incident severe hypoglycaemia in the FDS2 were: older age; higher educational attainment; alcohol consumption; current smoking; sulphonylurea/insulin treatment; prior severe hypoglycaemia; renal impairment; and plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP). The same variables except smoking were associated with frequency of severe hypoglycaemia. Most of these risk factors paralleled those in the FDS1, but current smoking and plasma NT-proBNP were novel. CONCLUSIONS The incidence and frequency of severe hypoglycaemia did not change between the Fremantle Diabetes Study phases but novel risk factors, including plasma NT-proBNP, were observed in the FDS2.

Evaluation of health utility values for diabetic complications, treatment regimens, glycemic control and other subjective symptoms in diabetic patients using the EQ-5D-5L. Acta Diabetol 2019; 56:309-319.

Abstract
AIMS This study aimed to reveal health utility values for diabetic complications and treatment regimens with adjustment for glycemic control and other clinical manifestations in a diabetic population. METHODS The EuroQol 5-Dimension 5-Level (EQ-5D-5L) health utility values for 4963 Japanese diabetic patients were analyzed using a multivariate regression model including major complications and treatment regiments (minimally adjusted model), and that additionally included glycemic control and other subjective symptoms (musculoskeletal, dental, respiratory, gastrointestinal, urinary, and cutaneous symptoms, and hearing impairment) (further adjusted model). RESULTS The mean utility value was 0.901 ± 0.137. In the minimally adjusted model, blindness, overt nephropathy, regular dialysis, cardiac symptom, sequelae of stroke, symptomatic peripheral neuropathy, decreased sensation, claudication, foot ulcer/gangrene, major amputation, and complex treatment regimens were significantly associated with lower utility values, whereas proliferative retinopathy without blindness, coronary artery disease without cardiac symptom, sequela-free cerebrovascular disease, asymptomatic peripheral artery disease, and minor amputation were not. Major complications and treatment regimens that showed significant association in the minimally adjusted model still presented significant impact on the utility decrement in the further adjusted model. However, most of their regression coefficients were lower in absolute value compared to those in the minimally adjusted model. CONCLUSIONS The utility decrement related to each diabetic complication varied with its severity and accompanying symptoms. Complex treatment regimens were independently associated with lower utility values. The utility decrement associated with diabetic complication and complex treatment regimens would be overestimated in the analysis without adjustment for glycemic control or other subjective symptoms.

Abstract
BACKGROUND Guidelines for Type 2 diabetes mellitus (T2DM) management in Japan provide physicians the discretion to select treatment options based on patient pathophysiology of the disease. There exists a wide variation of preference for initial antidiabetes drugs (AD). The current database analysis aimed to understand the real world treatment patterns in drug-naive patients with T2DM in Japan. METHODS We analyzed data of patients (≥ 18 years) diagnosed with T2DM between October 2012 and September 2016 from the Medical Data Vision, a Diagnosis Procedure Combination database. The primary objective was to determine the proportion of T2DM patients receiving each type of treatment as first-line therapy among the drug-naive cohort. RESULTS Of the 436,546 drug-naive patients, 224,761 received their first-line T2DM treatment in the outpatient setting. The mean age of the patient population was 65.6 years at index date. Dipeptidyl peptidase-4 (DPP-4) inhibitor was the most prescribed (56.8%) outpatient AD monotherapy, followed by metformin (15.4%). DPP-4 inhibitors were prescribed over metformin in patients with renal disease (odds ratio [OR]: 4.20; p < 0.0001), coronary heart disease and stroke (OR: 2.22; p < 0.0001). Male (OR: 1.03; p = 0.0026), presence of diabetic complications [retinopathy (OR: 1.33; p < 0.0001), neuropathy (OR: 1.05; p = 0.0037), nephropathy (OR: 1.08; p < 0.0001)] and a high baseline HbA1c (OR: 1.45; p < 0.0001) received treatment intensification during 180 days. CONCLUSION DPP-4 inhibitors were the most prevalent first-line T2DM treatment followed by metformin in Japan. The findings from this retrospective analysis also support the previously published web survey results and can help understand the real world utilization of T2DM treatment.Trial registration Retrospectively registered.

The effect of cassia seed extract on the regulation of the LKB1-AMPK-GLUT4 signaling pathway in the skeletal muscle of diabetic rats to improve the insulin sensitivity of the skeletal muscle. Diabetol Metab Syndr 2019; 11:108. [PMID: 31890042 PMCID: PMC6924081 DOI: 10.1186/s13098-019-0504-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2019] [Accepted: 12/09/2019] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND This study aimed to observe the hypoglycemic effect of cassia seed extract in rats with type-2 diabetes mellitus and its effect on reducing insulin resistance in the skeletal muscle. METHODS 50 rats were randomly divided into the normal, model, high-dose, middle-dose, and low-dose groups of cassia seed extract (n = 10 each). A high-fat diet combined with streptozotocin administration was adopted to build type 2 diabetes models. The cassia seed extract groups were fed different concentrations cassia seed extract while the normal and model groups were fed the same volume of normal saline. The weight, FINS, GIR, insulin tolerance, blood glucose and blood lipid level, oxidative stress indices and expressions related to the LKB1-AMPK-GLUT4 pathway were detected and compared between the two groups. RESULTS Compared with the normal group, the model group showed lower weight, glucose infusion rate and expressions related to LKB1-AMPK-GLUT4 pathway and higher FINS, insulin tolerance, blood glucose and blood lipid level and oxidative stress indices (all P < 0.05). Compared with the model group, higher weight, glucose infusion rate and expressions related to LKB1-AMPK-GLUT4 pathway and lower FINS, insulin tolerance, blood glucose and blood lipid level and oxidative stress indices were observed in all groups that were administered cassia see extract (all P < 0.05). CONCLUSION Cassia seed extract could noticeably improve the insulin resistance of diabetic rats and enhance the insulin sensitivity of their skeletal muscles. Its mechanism may be related to damage repair of the LKB1-AMPK-GLUT4 signaling pathway and oxidative stress in the skeletal muscle.
