Sulfonylurea prescription patterns in elderly patients with type 2 diabetes mellitus: A comprehensive analysis of real-world data from pharmacies in Japan. J Diabetes Investig 2024. [PMID: 39226073 DOI: 10.1111/jdi.14302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 07/29/2024] [Accepted: 08/15/2024] [Indexed: 09/04/2024] Open
Abstract
AIMS/INTRODUCTION The study aim was to investigate sulfonylurea prescription patterns in elderly patients (age ≥65 years) with type 2 diabetes mellitus in Japan. Sulfonylurea use among older adults has been insufficiently examined, despite the associated risks of hypoglycemia. MATERIALS AND METHODS This retrospective cross-sectional survey entailed analysis of Japanese pharmacy data, extracted from the Musubi database, for patients (age 20-100 years) prescribed sulfonylureas between November 2022 and October 2023. Dose distribution, adherence to the Diabetes Treatment Guidelines for the Elderly 2023 and coprescription of other diabetes medications were investigated. RESULTS Of the total 91,229 patients, 80.1% were prescribed glimepiride, 16.3% gliclazide and 3.6% glibenclamide. In patients aged ≥65 years, exceeding the recommended dose (>1 mg/day for glimepiride, >40 mg/day for gliclazide) was numerically higher for glimepiride (25.0%) than for gliclazide (7.8%). The most common prescribing patterns were quadruple therapy with a sulfonylurea, a dipeptidyl peptidase-4 inhibitor, an sodium-glucose transporter 2 inhibitor and a biguanide in patients aged 65 to <75 years, and dual therapy with a sulfonylurea and a dipeptidyl peptidase-4 inhibitor in patients aged ≥75 years. Unfortunately, glinide was coprescribed for 338 (0.5%) of elderly patients. Insulin was coprescribed for 3,682 (5.6%) of elderly patients. CONCLUSIONS Analysis of real-world sulfonylurea prescription data found guideline non-adherence, namely, excessive prescription of glimepiride, use of glibenclamide in elderly patients, and common coprescription with dipeptidyl peptidase-4 inhibitors. These findings might provide an opportunity to reconsider the treatment of patients with type 2 diabetes mellitus who are over-prescribed sulfonylureas to reduce residual risks, such as hypoglycemia.

Effects of continuous positive airway pressure therapy on glucose metabolism in patients with obstructive sleep apnoea and type 2 diabetes: a systematic review and meta-analysis. Eur Respir Rev 2023; 32:230083. [PMID: 37673425 PMCID: PMC10481331 DOI: 10.1183/16000617.0083-2023] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 06/27/2023] [Indexed: 09/08/2023] Open
Abstract
Obstructive sleep apnoea is a highly prevalent chronic disorder and has been shown to be associated with disturbed glucose metabolism and type 2 diabetes. However, the evidence from individual clinical trials on the effect of continuous positive airway pressure (CPAP) treatment on glycaemic control in patients with co-existing obstructive sleep apnoea and type 2 diabetes remains controversial. A systematic review of randomised controlled trials assessing the effect of CPAP on glycaemic control in patients with obstructive sleep apnoea and type 2 diabetes was conducted using the databases MEDLINE, Embase, Cochrane and Scopus up to December 2022. Meta-analysis using a random-effect model was performed for outcomes that were reported in at least two randomised controlled trials. From 3031 records screened, 11 RCTs with a total of 964 patients were included for analysis. CPAP treatment led to a significant reduction in haemoglobin A1c (HbA1c) (mean difference -0.24%, 95% CI -0.43- -0.06%, p=0.001) compared to inactive control groups. Meta-regression showed a significant association between reduction in HbA1c and hours of nightly CPAP usage. CPAP therapy seems to significantly improve HbA1c and thus long-term glycaemic control in patients with type 2 diabetes and obstructive sleep apnoea. The amount of improvement is dependent on the hours of usage of CPAP and thus optimal adherence to CPAP should be a primary goal in these patients.

Management of Diabetes and Hypertension within the Gulf Region: Updates on Treatment Practices and Therapies. Diabetes Ther 2022; 13:1253-1280. [PMID: 35679010 PMCID: PMC9178531 DOI: 10.1007/s13300-022-01282-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 05/17/2022] [Indexed: 11/20/2022] Open
Abstract
Cardiovascular disease (CVD) is a leading cause of death globally, driven by the high rates of risk factors, such as diabetes and hypertension. As the prevalence of these risk factors is particularly high in the Gulf region, better diagnosis and management of type 2 diabetes (T2D) and hypertension has the potential to dramatically reduce adverse cardiovascular outcomes for individuals in that part of the world. This article provides a summary of presentations made during the EVIDENT summit, a virtual symposium on Evidence in Diabetes and Hypertension, held in September 2021, including a review of the various guidelines for both T2D and hypertension, as well as recent findings relevant to the safety and efficacy for therapies relating to these conditions. Of relevance to the Gulf region, the risk of hypoglycaemia with sulfonylureas during Ramadan was reviewed. For the management of T2D, sulfonylureas have been a long-standing medication used to achieve glycaemic control; however, differences have emerged between early and later generations, with recent studies suggesting improvements in the safety profiles of late-generation sulfonylureas. For patients with hypertension, incremental therapy changes are recommended to reduce the risk of cardiovascular complications that are associated with increasing blood pressure. For first-line therapy, angiotensin-converting enzyme inhibitors (ACEi), such as perindopril, have been demonstrated to reduce the risk of cardiovascular and all-cause mortality. The addition of calcium channel blockers and diuretics to ACEi has been shown to be effective in patients with poorly controlled hypertension. The different renin-angiotensin-aldosterone system inhibitors are reviewed, and the benefit of combination therapies, including amlodipine and indapamide in patients with difficult-to-control hypertension, is investigated. The benefits of lifestyle modifications for these patients are also discussed, with important clinical considerations that are expected to inform patient management in daily clinical practice.

Abstract
Background:
Persistent hyperglycemia in diabetes mellitus (DM) is considered as the leading cause of morbidity and mortality associated with both microvascular and macrovascular complications and has a greater economic impact. This study aimed to assess the impact of socioeconomic status, prescribing patterns, and patient compliance in type 2 diabetes mellitus patients.
Method:
This study was carried out in the department of medicine and diabetic clinic of Hakeem Abdul Hameed (HAH) Centenary Hospital at Hamdard University, New Delhi, India. We conducted a prospective observational study on prescribing patterns and monitoring of adverse drug reactions (ADRs) in patients with type 2 DM (T2DM) taking standard care. We enrolled 150 confirmed cases and data was obtained from pre-validated questionnaires and then coded and analyzed to observe the association between variables.
Results:
The glycosylated haemoglobin level in 56 % of cases was between 6.4 to 8.0 and cardiovascular complications were observed as the major comorbidities. 45.33 % of cases were on mono drug therapy and Metformin (23. 52 %) was the drug of choice followed by Glimepiride (23.52 %). Among the dual drug therapies, Sitagliptin with Metformin and in triple-drug therapy, Glimepiride concurrent with Metformin and Voglibose was the most preferred drug in the treatment of T2DM. Sitagliptin was observed to be a major patient burden (46.213 USD). In only 7.33 % of cases, we observed definite ADR in T2DM patients. Underprivileged awareness, mainly due to low literacy, was a major concern in the development of new cases of T2DM.
Conclusion:
We observed better patient compliance and disease awareness program is required to be implemented. The use of oral hypoglycaemic drugs is still dominant in clinical practice and cardiovascular disorders as comorbidities emerge as a greater challenge in terms of patient outcome and cost burden.

Abstract
AIMS/INTRODUCTION Knowing the collective clinical factors that determine patient response to glucose-lowering medication would be beneficial in the treatment of type 2 diabetes. We carried out a retrospective cohort study to explore the combination of clinical factors involved in its therapeutic efficacy. MATERIALS AND METHODS The results of cohort studies retrieved using the CoDiC® database across Japan from January 2005 to July 2018 were analyzed based on criterion that using insulin therapy indicates severe type 2 diabetes. RESULTS A logistic regression analysis showed that age at diagnosis, disease duration, hemoglobin A1c (HbA1c) and serum C-peptide reactivity (CPR) at medication commencement were associated with the probability of insulin treatment. Receiver operating characteristic curve showed that these clinical factors predicted insulin treatment positivity with an area under the curve of >0.600. The area under the curve increased to 0.674 and 0.720 for the disease duration-to-age at diagnosis ratio and HbA1c-to-CPR ratio, respectively. Furthermore, area under the curve increased to 0.727 and 0.750 in the indices (duration-to-age ratio at diagnosis × 43 + HbA1c) and (duration-to-age ration at diagnosis × 21 + HbA1c-to-CPR ratio), respectively. After stratification to three groups according to the indices, monthly HbA1c levels during 6 months of treatment were higher in the upper one-third than in the lower one-third of patients, and many patients did not achieve the target HbA1c level (53 mmol/mol) in the upper one-third, although greater than fourfold more patients were administered insulin in the upper one-third. CONCLUSIONS The combination of disease duration-to-age at diagnosis and HbA1c-to-CPR ratios is a collective risk factor that predicts response to the medications.

Abstract
AIMS To identify patient-specific factors associated with early metformin treatment modification among type 2 diabetes patients before and after implementation of the updated 2015 NICE (National Institute for Health and Care Excellence) guideline. METHODS We conducted a population-based cohort study using data from the Clinical Practice Research Datalink GOLD database (2009-2016). Patients ≥ 18 years, newly treated with metformin only, during the period of valid data collection were included. The first prescription defined start of follow-up. Determinants of treatment modification in two cohorts (before and after implementation of the updated guideline) were studied by time-dependent Cox proportional hazards regression. RESULTS After implementation of the updated guideline, patients were less likely to receive sulphonylureas (62.3% vs 41.3%) or thiazolidediones (4.7% vs 2.2%) and more likely to receive dipeptidyl peptidase-4 inhibitors (15.8% vs 27.1%) or sodium-glucose cotransporter-2 inhibitors (0.8% vs 9.9%). Some determinants influenced general practitioners' prescribing differently after implementation of the updated guideline compared to before, including a high body mass index and heart failure. CONCLUSIONS Our results indicate that a first step towards tailored prescribing has been made. However, not all determinants that are important to consider when prescribing second-line glucose-lowering agents were of influence on general practitioners' prescribing.

Abstract
Japan's guidelines emphasize tailored therapy, but do not guide physicians on the use of a specific regimen in drug-naive patients. The role of long-term initial therapy could be important in key elements of diabetes treatment, such as continuation of the initially prescribed drug. We investigated the frequency of occurrence to treatment intensification after the initiation of metformin or dipeptidyl peptidase-4 inhibitor treatment. In multivariable-adjusted Cox proportional hazards models, initiation of dipeptidyl peptidase-4 inhibitor was associated with a low hazard of intensification. The findings of this survey showed that dipeptidyl peptidase-4 inhibitors were the preferred first-line treatment in Japan because of the high continuation rate of the treatment and hemoglobin A1c-lowering effect. This information would provide guidance in selecting initial hypoglycemic drugs to optimize the treatment of type 2 diabetes mellitus patients in Japan and Asia.

Abstract
AIMS/INTRODUCTION To evaluate linagliptin prescribing in type 2 diabetes mellitus patients with different comorbidities, an expanded Japanese post-marketing surveillance also collected baseline data for patients initiating other glucose-lowering drugs. MATERIALS AND METHODS Patients initiating linagliptin monotherapy were enrolled, then the next patient starting monotherapy with another glucose-lowering drug was enrolled (2012-2014). Baseline data were collected and analyzed by the Medical Dictionary for Regulatory Activities system organ class. Analyses were descriptive, and meaningful differences defined as absolute standardized difference >10%. RESULTS Over 4,200 type 2 diabetes mellitus patients were enrolled. Most system-organ class comorbidities were more common in patients initiating linagliptin versus other glucose-lowering drugs, with meaningful differences observed for metabolism/nutritional (50.5 vs 45.5%, respectively), cardiac (12.2 vs 8.6%, respectively), vascular (56.4 vs 51.3%, respectively) and renal/urinary disorders (9.9 vs 5.7%, respectively). CONCLUSIONS Expanding the linagliptin Japanese post-marketing surveillance revealed linagliptin prescribing to a type 2 diabetes mellitus population with more comorbidities versus other glucose-lowering drugs. Although such preferential prescribing might be expected, as linagliptin requires no dose adjustment or monitoring in renally or hepatically impaired patients, this innovative post-marketing surveillance approach generated important evidence that could only be shown in such a non-randomized comparative study. These data generated insights important for the design and interpretation of observational studies and spontaneous reports, which are key for public health.

Abstract
5-Aminolevulinic acid (5-ALA) is a delta amino acid naturally present in every living cell of the human body. 5-ALA is produced in the mitochondria as the first product of the porphyrin synthesis pathway and composes heme; exogenously supplemented 5-ALA helps in upregulating mitochondrial functions. Mitochondrial dysfunction has been associated with the pathophysiology of diabetes mellitus. Thus, in this review, we evaluate the mechanisms of action and adverse effects of common medications used to treat type 2 diabetes mellitus as well as 5-ALA including its mechanism and possible use in diabetes management.

Abstract
BACKGROUND The global pandemic of type 2 diabetes mellitus (T2DM) is an enormous clinical and socioeconomic burden. Biguanides and DPP-4 inhibitors (DPP-4i) are the most commonly used therapies in Japanese T2DM patients. When glycemic control is not adequate despite combination of these drugs, there is no consensus on the next step drug. Systematic reviews and meta-analyses of previous trials have indicated that glycemic control with triple combination therapies yields similar results. Thus, beneficial effects on cardiovascular risk factors may be important. The present study was designed to evaluate body fat percentage and several insulin resistance parameters after addition of tofogliflozin or glimepiride to the regimens of patients being treated with metformin and a DPP-4 inhibitor but failing to attain adequate blood glucose control. METHODS Sodium glucose cotransporter-2 inhibitor, tofogliflozin versus glimepiride, comparative trial in patients with type 2 diabetes on body composition is an ongoing, multicenter, prospective, randomized, open-label, parallel-group trial. T2DM patients treated with metformin/DPP-4 inhibitor dual therapy have been recruited and randomly assigned to 20 mg/day tofogliflozin (n = 32) or 0.5 mg/day glimepiride (n = 32) groups, with either of these drugs being added to pre-existing regimens for 24 weeks. PLANNED OUTCOMES The primary endpoint is the change in body fat percentage from baseline to 24 weeks. The secondary outcomes are changes in body composition other than fat percentage, body weight, parameters related to glycemic control and β-cell function, parameters related to lipids and arteriosclerosis, parameters related to liver function, parameters related to diabetic nephropathy, and uric acid levels. Safety parameters will also be analyzed. This is the first trial comparing the effects and safety of adding an SGLT2i and a sulfonylurea as the third-line oral agent to metformin/DPP-4i dual therapy. The results will provide valuable information for choosing third-line oral agents. TRIAL REGISTRATION UMIN000026161. FUNDING Kowa Co. Ltd. and Kowa Pharmaceutical Co. Ltd., Tokyo, Japan.

Abstract
INTRODUCTION Canagliflozin, a sodium-glucose co-transporter-2 (SGLT2) inhibitor, improves various cardiometabolic parameters. Although canagliflozin was originally discovered in Japan, no comprehensive summary of its effects in Japanese patients has been reported. As differences exist in the pathologic features of diabetes between Japanese and non-Japanese populations, it is important to consolidate Japanese data for canagliflozin. Areas covered: The authors summarize Japanese clinical trial and post-marketing surveillance data for canagliflozin, and make comparisons with non-Japanese data. They also consider the therapeutic potential of canagliflozin in Japanese patients by presenting results from the CANagliflozin cardioVascular Assessment Study (CANVAS) Program. Expert opinion: In Japanese patients, canagliflozin 100 mg, administered as monotherapy or combination therapy, improved blood glucose, body weight, and blood pressure, and was well tolerated; the efficacy and safety profiles were comparable to previous clinical studies in other countries. In the CANVAS Program, canagliflozin reduced major cardiovascular events, and although Japan was not included in this program, canagliflozin may have cardiovascular benefits in Japanese patients, in whom control of multiple risk factors is important for preventing diabetic complications. Patients with high cardiovascular risk often have multiple comorbidities, so it is important to consider the risk-benefit balance of using SGLT2 inhibitors in individual patients.

Abstract
BACKGROUND This post-marketing surveillance examined the safety and efficacy of long-term teneligliptin therapy in Japanese patients. RESEARCH DESIGN AND METHODS We report interim results (cut-off date: 28 June 2017) of a 3-year PMS undertaken in subjects with type 2 diabetes mellitus (T2DM). Survey items included demographics, treatments, adverse drug reactions (ADRs), and laboratory variables. A subgroup analysis was also performed across three age groups (<65 years; 65 to <75 years; ≥75 years). Main outcome measures were incidence of ADRs, laboratory variables, and change in glycated hemoglobin (HbA1c) from baseline over time. RESULTS Of 11,677 patients registered, data from 10,532 patients (6,338 males/4,194 females) were analyzed for the safety analysis set; the median administration period was 731 days. Overall, ADRs and serious ADRs were reported in 364 (3.46%) and 91 patients (0.86%), respectively. The most common ADRs were all hypoglycemia (0.32%), constipation (0.27%), and hepatic function abnormal (0.24%). No change in mean body weight occurred, and a reduction in mean HbA1c was observed until 2 years. The safety and efficacy profiles did not differ markedly among the three age groups. CONCLUSIONS These interim results show that teneligliptin was well tolerated and improved hyperglycemia in Japanese patients with T2DM in clinical practice.

J Diabetes Investig 2016; 7:386-95. [PMID: 27330726 PMCID: PMC4847894 DOI: 10.1111/jdi.12430] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2015] [Revised: 08/27/2015] [Accepted: 09/09/2015] [Indexed: 01/03/2023] Open
Abstract
AIMS/INTRODUCTION We carried out an observational cohort study to examine the relationship between the efficacy of oral antidiabetic drugs and clinical features in type 2 diabetics. MATERIALS AND METHODS We analyzed the CoDiC(®) database of the Japan Diabetes Data Management Study Group across 67 institutions in Japan. In a total of 3,698 drug-naïve patients who were initiated with metformin, dipeptidyl peptidase-4 inhibitor (DPP-4i) or sulfonylurea (SU) from 2007 to 2012, we evaluated body mass index (BMI) and hemoglobin A1c (HbA1c). The patients were stratified according to their clinical features, and matched using a propensity score to adjust for baseline factors. RESULTS HbA1c was reduced with all drugs, with the largest effect elicited by DPP-4i and the smallest by SU (P = 0.00). HbA1c increased with SU after 6 months in the patients stratified by an age-of-onset of <50 years (P = 0.00). BMI increased with SU in the patients stratified by a BMI of <25 (P = 0.00), and decreased with metformin in the patients with a BMI >25 (P = 0.00). The reduction in HbA1c was larger in patients with HbA1c of ≥8%, compared with that in patients with HbA1c of <8% (P = 0.00). HbA1c during the study period was higher in patients who were added to or swapped with other drug(s), than in patients continued on the original drug (P = 0.00). CONCLUSIONS The effect on bodyweight and glycemic control differed among metformin, DPP-4i and SU, and the difference was associated with clinical features.
