Abstract
Type 2 diabetes (T2D) is a disease characterized by heterogeneously progressive loss of islet β cell insulin secretion usually occurring after the presence of insulin resistance (IR) and it is one component of metabolic syndrome (MS), and we named it metabolic dysfunction syndrome (MDS). The pathogenesis of T2D is not fully understood, with IR and β cell dysfunction playing central roles in its pathophysiology. Dyslipidemia, hyperglycemia, along with other metabolic disorders, results in IR and/or islet β cell dysfunction via some shared pathways, such as inflammation, endoplasmic reticulum stress (ERS), oxidative stress, and ectopic lipid deposition. There is currently no cure for T2D, but it can be prevented or in remission by lifestyle intervention and/or some medication. If prevention fails, holistic and personalized management should be taken as soon as possible through timely detection and diagnosis, considering target organ protection, comorbidities, treatment goals, and other factors in reality. T2D is often accompanied by other components of MDS, such as preobesity/obesity, metabolic dysfunction associated steatotic liver disease, dyslipidemia, which usually occurs before it, and they are considered as the upstream diseases of T2D. It is more appropriate to call "diabetic complications" as "MDS-related target organ damage (TOD)", since their development involves not only hyperglycemia but also other metabolic disorders of MDS, promoting an up-to-date management philosophy. In this review, we aim to summarize the underlying mechanism, screening, diagnosis, prevention, and treatment of T2D, especially regarding the personalized selection of hypoglycemic agents and holistic management based on the concept of "MDS-related TOD".

Efficacy and tolerability of initial triple combination therapy with metformin, dapagliflozin and saxagliptin compared with stepwise add-on therapy in drug-naïve patients with type 2 diabetes (TRIPLE-AXEL study): A multicentre, randomized, 104-week, open-label, active-controlled trial. Diabetes Obes Metab 2024; 26:3642-3652. [PMID: 38853720 DOI: 10.1111/dom.15705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 05/13/2024] [Accepted: 05/23/2024] [Indexed: 06/11/2024]
Abstract
AIM To evaluate the efficacy and tolerability of an initial triple combination therapy (TCT) compared with conventional stepwise add-on therapy (SAT) in patients with newly diagnosed type 2 diabetes (T2D). MATERIALS AND METHODS This multicentre, randomized, 104-week, open-label trial randomized 105 patients with drug-naïve T2D (with HbA1c level ≥ 8.0%, < 11.0%) to the TCT (1000 mg of metformin, 10 mg of dapagliflozin and 5 mg of saxagliptin once daily) or SAT (initiated with metformin, followed by glimepiride and sitagliptin) groups. The primary outcome was the proportion of patients who achieved an HbA1c level of less than 6.5% without hypoglycaemia, weight gain of 5% or higher, or discontinuation of drugs because of adverse events at week 104. RESULTS HbA1c reduction from baseline at week 104 was similar between the groups (the least squares mean change was -2.56% in the TCT group vs. -2.75% in the SAT group). The primary outcome was achieved in 39.0% and 17.1% of the TCT and SAT groups, respectively, with a risk difference of 22.0 (95% confidence interval 3.0, 40.8; P = .027). HbA1c level less than 6.5% at week 104 was 46.3% in both the TCT and SAT groups, whereas the incidence of hypoglycaemia, weight gain, or discontinuation of drugs was 16.7% and 62.0% in the TCT and SAT groups, respectively (P < .001). TCT was well-tolerated and had fewer adverse events than SAT. CONCLUSIONS Among newly diagnosed patients with T2D, initial TCT effectively lowered HbA1c levels with higher tolerability and safety than SAT for 104 weeks, suggesting a novel strategy for initial combination therapy in T2D patients.

Mahmoud F, Mueller T, Mullen A, Sainsbury C, Rushworth GF, Kurdi A. Patterns of initial and first-intensifying antidiabetic drug utilization among patients with type 2 diabetes mellitus in Scotland, 2010-2020: A retrospective population-based cohort study. Diabetes Obes Metab 2024; 26:2684-2694. [PMID: 38558305 DOI: 10.1111/dom.15584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 03/13/2024] [Accepted: 03/19/2024] [Indexed: 04/04/2024]
Abstract
AIM To evaluate the utilization and prescribing patterns of antidiabetic drugs (ADDs) for patients with type 2 diabetes mellitus (T2DM) at treatment initiation and first intensification. METHODS A retrospective cohort study was performed using linked routinely collected data of patients with T2DM who received ADDs between January 2010 and December 2020 in Scotland. The prescribing patterns were quantified using frequency/percentages, absolute/relative change, and trend tests. RESULTS Overall, 145 909 new ADD users were identified, with approximately 91% (N = 132 382) of patients receiving a single ADD at first treatment initiation. Metformin was the most often prescribed monotherapy (N = 118 737, 89.69%). A total of 50 731 patients (39.40%) who were started on metformin (N = 46 730/118 737, 39.36%) or sulphonylurea (SU; N = 4001/10 029, 39.89%) monotherapy had their treatment intensified with one or more additional ADD. Most initial-metformin (45 963/46 730; 98.36%) and initial-SU users (3894/4001; 97.33%) who added further drugs were intensified with single ADDs. SUs (22 197/45 963; 48.29%) were the most common first-intensifying monotherapy after initial metformin use, but these were replaced by sodium-glucose cotransporter-2 (SGLT2) inhibitors in 2019 (SGLT2 inhibitors: 2039/6065, 33.62% vs. SUs: 1924/6065, 31.72%). Metformin was the most frequently added monotherapy to initial SU use (2924/3894, 75.09%). Although the majority of patients received a single ADD, the use of combination therapy significantly increased over time. Nevertheless, there was a significant increasing trend towards prescribing the newer ADD classes (SGLT2 inhibitors, dipeptidyl peptidase-4 inhibitors) as monotherapy or in combination compared with the older ones (SUs, insulin, thiazolidinediones) at both drug initiation and first intensification. CONCLUSIONS An overall increasing trend in prescribing the newer ADD classes compared to older ADDs was observed. However, metformin remained the most commonly prescribed first-line ADD, while SGLT2 inhibitors replaced SUs as the most common add-on therapy to initial metformin use in 2019.

Abstract
Management of type 2 diabetes mellitus (T2DM) largely relies on medication adherence of individuals with diabetes to achieve optimal glycemic control. The economic burden of diabetes could impede adherence, leading to a reduction in treatment efficacy and increased risk of complications. Furthermore, monotherapy in diabetes is losing traction due to its ineffectiveness in achieving early and sustained optimal glycemic control in a significant proportion of the population. Hence, clinicians prefer combination treatment due to their improved efficacy and safety. Considering these factors, the current review highlights the safety and efficacy of the affordable combination therapies, a dual therapy, glipizide + metformin, and a triple-drug combination of glimepiride + metformin + pioglitazone and its applicability in the management of T2DM among individuals with diabetes in India.

Abstract
BACKGRUOUND We investigated the long-term efficacy and safety of initial triple therapy using metformin, a dipeptidyl peptidase-4 inhibitor, and a sodium-glucose cotransporter-2 inhibitor, in patients with type 2 diabetes mellitus. METHODS We enrolled 170 drug-naïve patients with glycosylated hemoglobin (HbA1c) level >7.5% who had started triple therapy (metformin, sitagliptin, and empagliflozin). Glycemic, metabolic, and urinary parameters were measured for 24 months. RESULTS After 24 months, HbA1c level decreased significantly from 11.0%±1.8% to 7.0%±1.7%. At 12 and 24 months, the rates of achievement of the glycemic target goal (HbA1c <7.0%) were 72.5% and 61.7%, respectively, and homeostasis model assessment of β-cell function and insulin resistance indices improved. Whole-body fat percentage decreased by 1.08%, and whole-body muscle percentage increased by 0.97% after 24 months. Fatty liver indices and albuminuria improved significantly. The concentration of ketone bodies was elevated at the baseline but decreased after 24 months. There were no serious adverse events, including ketoacidosis. CONCLUSION Initial triple combination therapy with metformin, sitagliptin, and empagliflozin led to achievement of the glycemic target goal, which was maintained for 24 months without severe hypoglycemia but with improved metabolic function and albuminuria. This combination therapy may be a good strategy for drug-naïve patients with type 2 diabetes mellitus.

Combinational application of the natural products 1-deoxynojirimycin and morin ameliorates insulin resistance and lipid accumulation in prediabetic mice. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 121:155106.

Abstract
BACKGROUND Prediabetes, a stage characterized by chronic inflammation, obesity and insulin resistance. Morin and 1-deoxynojirimycin (DNJ) are natural flavonoids and alkaloids extracted from Morus nigra L., exhibiting anti-hyperglycemic efficacy. However, the benefits of DNJ are shadowed by the adverse events, and the mechanism of morin in anti-diabetes remains under investigation. PURPOSE In this study, the combinational efficacy and mechanisms of DNJ and morin in ameliorating insulin resistance and pre-diabetes were investigated. METHODS The mice model with prediabetes and Alpha mouse liver-12 (AML-12) cell model with insulin resistance were established. The anti-prediabetic efficacy of the drug combination was determined via analyzing the blood glucose, lipid profiles and inflammatory factors. The application of network pharmacology provided guidance for the research mechanism. RESULTS In our study, the intervention of morin ameliorated the insulin resistance via activating the Peroxisome proliferator-activated receptor γ (PPARγ). However, PPARγ activation leaded to the lipid accumulation in prediabetic mice. The combination of 5 mg/kg dose of DNJ and 25 mg/kg morin effectively hindered the progression of T2DM by 87.56%, which was achieved via inhibition of Suppressors of cytokine signaling 3 (SOCS3) and promotion of PPARγ as well as SOCS2 expression. Furthermore, this treatment exhibited notable capabilities in combating dyslipidemia and adipogenesis, achieved by suppressing the Cluster of differentiation 36/ Sterol-regulatory element binding proteins-1/ Fatty acid synthetase (CD36/Serbp1/Fas) signaling. CONCLUSION This research confirmed that the drug combination of DNJ and morin in ameliorating insulin resistance and lipid accumulation, and revealed the potential mechanisms. In summary, the combination of DNJ and morin is an underlying alternative pharmaceutical composition in T2DM prevention.

Abstract
General practitioners see in their consultation a a significant number of patients at high vascular risk (VR). The European Guidelines for Cardiovascular Disease Prevention (2021) recommend a new risk classification and intervention strategies on on vascular risk factors (RF), with the aim of providing a shared decision-making recommendations between professionals and patients. In this document we present a critical analysis of these guidelines, offering possible solutions that can be implemented in Primary Care. It should be noted that there are positive aspects (lights) such as that the SCORE2 (from forty to sixty-nine years) and SCORE2-OP models (from seventy to eighty-nine years) are based on more current cohorts and measure cardiovascular risk in a more accurately manner. In addition, it is proposed to differentiate different risk thresholds according to age-groups. For sake of practicality, cardiovascular risk can be estimated using different websites with the new computer models. However, among the negative aspects (shadows), it seems to be add complexity implementing nine subgroups of subjects according to their age or level of risk, with a defined thresholds that could cause a substantial increase in the potential number of subjects susceptible to treatment without a clear evidence that supports it. In addition, two-step RF interventions could delay achievement of therapeutic goals, especially in very high-risk patients, diabetics, or patients with cardiovascular disease. Given these limitations, in this document we propose practical recommendations in order to simplify and facilitate the implementation of the guideline in primary care.

Abstract
Diabetes mellitus (DM) is a group of metabolic diseases characterized by hyperglycemia that can occur in children, adults, elderly people, and pregnant women. Oxidative stress is a significant adverse factor in the pathogenesis of DM, especially type 2 diabetes mellitus (T2DM), and metabolic syndrome. Natural polysaccharides are macromolecular compounds widely distributed in nature. Some polysaccharides derived from edible plants and microorganisms were reported as early as 10 years ago. However, the structural characterization of polysaccharides and their therapeutic mechanisms in diabetes are relatively shallow, limiting the application of polysaccharides. With further research, more natural polysaccharides have been reported to have antioxidant activity and therapeutic effects in diabetes, including plant polysaccharides, microbial polysaccharides, and polysaccharides from marine organisms and animals. Therefore, this paper summarizes the natural polysaccharides that have therapeutic potential for diabetes in the past 5 years, elucidating their pharmacological mechanisms and identified primary structures. It is expected to provide some reference for the application of polysaccharides, and provide a valuable resource for the development of new diabetic drugs.

Abstract
AIM To evaluate the efficacy and safety of the initial combination therapy versus a stepwise approach in newly diagnosed type 2 diabetes (T2D) by conducting a systematic review and meta-analysis of observational cohort studies and randomized controlled trials (RCTs). METHODS Studies were identified from MEDLINE, Embase, the Cochrane Library, and through search of bibliographies to January 2022. Study-specific risk ratios (RRs) and mean differences with 95% confidence intervals (CIs) were pooled. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. RESULTS Eight articles including four unique RCTs (n = 5527 participants) and one observational cohort study (n = 200) that compared initial combination therapy versus stepwise therapy were included. The RR for myocardial infarction comparing initial combination therapy versus stepwise therapy was 1.21 (95% CI 0.74-2.00). Initial combination therapy reduced levels of fasting plasma glucose and glycated haemoglobin: mean differences -0.97 mmol/L (95% CI -1.41, -0.53) and -24.92 mmol/mol (95% CI -25.67, -24.27), respectively. Initial combination therapy versus stepwise therapy reduced lipid levels, blood pressure and intima media thickness, with no differences in body composition variables, neuropathy, retinopathy or adverse events. Single-study results showed that initial combination therapy reduced creatinine levels and urine albumin excretion rate. The quality of the evidence ranged from moderate to very low. CONCLUSIONS Except for improving cardiometabolic and glycaemic variables, a limited number of studies characterized by small sample sizes show that initial combination therapy for newly diagnosed T2D may be similar in efficacy and safety to stepwise therapy with respect to cardio-renal outcomes. There is a lack of sufficient evidence to recommend initial combination therapy with glucose-lowering agents in newly diagnosed T2D with the aim of preventing cardio-renal outcomes. Definitive RCTs are warranted.

Abstract
SIGNIFICANCE Combining 0.01% atropine with soft multifocal contact lenses (SMCLs) failed to demonstrate better myopia control than SMCLs alone. PURPOSE The Bifocal & Atropine in Myopia (BAM) Study investigated whether combining 0.01% atropine and SMCLs with +2.50-D add power leads to greater slowing of myopia progression and axial elongation than SMCLs alone. METHODS Participants of the BAM Study wore SMCLs with +2.50-D add power daily and administered 0.01% atropine eye drops nightly (n = 46). The BAM subjects (bifocal-atropine) were age-matched to 46 participants in the Bifocal Lenses in Nearsighted Kids Study who wore SMCLs with +2.50-D add power (bifocal) and 46 Bifocal Lenses in Nearsighted Kids participants who wore single-vision contact lenses (single vision). The primary outcome was the 3-year change in spherical equivalent refractive error determined by cycloplegic autorefraction, and the 3-year change in axial elongation was also evaluated. RESULTS Of the total 138 subjects, the mean ± standard deviation age was 10.1 ± 1.2 years, and the mean ± standard deviation spherical equivalent was -2.28 ± 0.89 D. The 3-year adjusted mean myopia progression was -0.52 D for bifocal-atropine, -0.55 D for bifocal, and -1.09 D for single vision. The difference in myopia progression was 0.03 D (95% confidence interval [CI], -0.14 to 0.21 D) for bifocal-atropine versus bifocal and 0.57 D (95% CI, 0.38 to 0.77 D) for bifocal-atropine versus single vision. The 3-year adjusted axial elongation was 0.31 mm for bifocal-atropine, 0.39 mm for bifocal, and 0.68 mm for single vision. The difference in axial elongation was -0.08 mm (95% CI, -0.16 to 0.002 mm) for bifocal-atropine versus bifocal and -0.37 mm (95% CI, -0.46 to -0.28 mm) for bifocal-atropine versus single vision. CONCLUSIONS Adding 0.01% atropine to SMCLs with +2.50-D add power failed to demonstrate better myopia control than SMCLs alone.

Abstract
Background Evidence is limited in comparing treatment modification by substitution or add‐on of glucose‐lowering medications in patients with type 2 diabetes. This observational study aims to compare switching versus add‐on of incretin‐based drugs among patients with type 2 diabetes on background sodium‐glucose cotransporter‐2 inhibitors (SGLT2i). Methods and Results This population‐based, retrospective cohort study was conducted using the IQVIA Medical Research Data, including adults with type 2 diabetes on background SGLT2i from 2005 to 2020. New users of incretin‐based drugs were allocated into the “Switch” group if they had discontinued SGLT2i treatment, or the “Add‐on” group if their background SGLT2i was continued. Baseline characteristics of patients were balanced between groups. Study outcomes were all‐cause mortality, cardiovascular diseases, kidney diseases, hypoglycemia, and ketoacidosis. Patients were observed from the index date of initiating incretin‐based drugs until the earliest of an outcome event, death, or data cut‐off date. Changes in anthropometric and metabolic parameters were also compared between groups from baseline to 12‐month follow‐up. A total of 2888 patients were included, classified into “Switch” (n=1461) or “Add‐on” group (n=1427). Median follow‐up was 18 months with 5183 person‐years. Overall, no significant differences in the risks of study outcomes were observed between groups; however, patients in the “Add‐on” group achieved significantly greater reductions in glycated hemoglobin, weight, percentage weight loss, and systolic blood pressure than their “Switch” counterparts. Conclusions Initiating incretin‐based drugs as add‐on among patients with type 2 diabetes on background SGLT2i was associated with risks of clinical end points comparable to switching treatments, in addition to better glycemic and weight control observed with the combination approach.

Abstract
The vascular endothelium is present within metabolic organs and actively regulates energy metabolism. Here we show osteocalcin, recognized as a bone-secreted metabolic hormone, is expressed in mouse primary endothelial cells isolated from heart, lung and liver. In human osteocalcin promoter-driven green fluorescent protein transgenic mice, green fluorescent protein signals are enriched in endothelial cells lining aorta, small vessels and capillaries and abundant in aorta, skeletal muscle and eye of adult mice. The depletion of lipoprotein receptor-related protein 1 induces osteocalcin through a Forkhead box O -dependent pathway in endothelial cells. Whereas depletion of osteocalcin abolishes the glucose-lowering effect of low-density lipoprotein receptor-related protein 1 depletion, osteocalcin treatment normalizes hyperglycemia in multiple mouse models. Mechanistically, osteocalcin receptor-G protein-coupled receptor family C group 6 member A and insulin-like-growth-factor-1 receptor are in the same complex with osteocalcin and required for osteocalcin-promoted insulin signaling pathway. Therefore, our results reveal an endocrine/paracrine role of endothelial cells in regulating insulin sensitivity, which may have therapeutic implications in treating diabetes and insulin resistance through manipulating vascular endothelium.

Abstract
Step-wise addition of antihyperglycemic agents (AHA) after the initiation of metformin monotherapy has been the traditional approach for the treatment of type 2 diabetes mellitus (T2DM) world-wide. Emerging evidence increasingly suggests that metformin-based combination therapy, especially with the newer AHA that lowers HbA1c glucose-dependently and do not potentiate hypoglycemia, could be a potentially better option for durable glycemic control with good tolerability compared to diabetes monotherapy. In this review, we descriptively analyzed the evidence available from the systematic reviews and meta-analyses of randomized head-to-head trials that reported the efficacy and safety outcomes of diabetes monotherapy, metformin-based combination therapies, and monotherapy versus metformin-based combination therapies.

Abstract
Metformin, gallic acid and a combination of both improved glucose metabolism and antioxidant status in diabetic rats. Metformin, gallic acid and a combination of both lowered levels of IL-6 and TNF-α in liver and pancreas of diabetic rats. Metformin, gallic acid and a combination of both decreased the expression of ATF4 in liver and pancreas of diabetic rats. Metformin/GA combination appeared more effective than metformin only and gallic acid only.
Over time, diabetes patients usually need combination therapy involving two or more agents, including phytonutrients to attain therapeutic targets. The purpose of this research is to elucidate the combined effect of metformin and gallic acid (GA) on glucose metabolism, inflammation as well as oxidative and endoplasmic reticulum (ER) stresses in fructose-fed diabetic rats. Thirty-five rats of Wistar strain were arbitrarily distributed into five groups, each containing seven animals as follows: normal control, diabetic control, groups administered 100 mg/kg bw metformin only, 50 mg/kg bw gallic acid only and a combination of both. Experimental animals were made diabetic by single injection of 40 mg/kg streptozotocin (intraperitoneally) subsequent to 14 days administration of 10 % fructose prior. Treatment of rats continued for 21 days following diabetes confirmation. Glucose and insulin levels as well as lipid profile were evaluated in the serum, while activities of catalase and superoxide dismutase were estimated in both liver and pancreas. In addition, levels of malondialdehyde, interleukin-6 and tumor necrosis factor-alpha, as well as expression of activating transcription factor-4 were evaluated in liver and pancreas of diabetic rats. Activities of glucose-6-phosphatase and glucokinase were also determined in liver of diabetic animals. Metformin only, GA only and combination of metformin and GA significantly improved antioxidant status and glucose homeostasis while inflammation and endoplasmic reticulum stress were significantly ameliorated in diabetic rats. Metformin/GA combination appeared to improve glucose metabolism by increasing insulin level and ameliorating the dysregulated activities of glucose metabolizing enzymes and ER stress better than either metformin only or GA only. It could be concluded that coadministration of metformin/GA produced a combined effect in ameliorating diabetes in Wistar rats and could be considered in treatment of diabetes.

Changes in fasting patterns during Ramadan, and associated clinical outcomes in adults with type 2 diabetes: A narrative review of epidemiological studies over the last 20 years. Diabetes Res Clin Pract 2021; 172:108584.

Abstract
Although religious guidance exempts some Muslims with type 2 diabetes from fasting during Ramadan, many choose to fast. The associated risks for fasting adults with diabetes includes hypoglycemia, hyperglycemia, ketoacidosis, dehydration, and thrombosis. Thus, it is important that healthcare professionals support individuals who choose to fast to minimize risks. We reviewed three epidemiologic studies to understand how fasting patterns during Ramadan and associated clinical outcomes in adults with type 2 diabetes have evolved over two decades (2000-2020). Over a period of time people with diabetes choosing to fast during Ramadan are displaying increasingly complex profiles in terms of their diabetes, with increased disease duration, greater body mass index, and elevated pre-Ramadan mean glycated hemoglobin levels. Despite this, in the most recent study, >85% of adults with type 2 diabetes still chose to fast. Increased risk of hypoglycemia remains a major concern despite some improvements over time, which could be attributable to enhanced education programs, and changes in treatment type and/or dose prior to and/or during Ramadan. Our review highlights the evolution in fasting patterns over two decades and serves as an update for healthcare professionals to provide appropriate guidance to ensure that Ramadan fasting is safe and rewarding.

Abstract
Type 2 diabetes (T2D) in the East Asian population is characterized by phenotypes such as low body mass index, an index of β-cell dysfunction, and higher percentage of body fat, an index of insulin resistance. These phenotypes/pathologies may predispose people to early onset of diabetes with increased risk of stroke and renal disease. Less than 50% of patients with T2D in East Asia achieve glycaemic targets recommended by national or regional guidelines, which may be attributable to knowledge and/or implementation gaps. Herein, we review the latest evidence with special reference to East Asian patients with T2D and present arguments for the need to use early combination therapy to intensify glycaemic control. This strategy is supported by the 5-year worldwide VERIFY study, which reported better glycaemic durability in newly diagnosed patients with T2D with a mean HbA1c of 6.9% treated with early combination therapy of vildagliptin plus metformin versus those treated with initial metformin monotherapy followed by addition of vildagliptin only with worsening glycaemic control. This paradigm shift of early intensified treatment is now recommended by the American Diabetes Association and the European Association for the Study of Diabetes. In order to translate these evidence to practice, increased awareness and strengthening of the healthcare system are needed to diagnose and manage patients with T2D early for combination therapy.

Abstract
BACKGROUND The sodium/glucose cotransporter-2 inhibitors (SGLT-2i) and glucagon-like-1 receptor agonists (GLP-1RA) are antidiabetic agents effective both in hemoglobin A1c (HbA1c) reduction (with a low risk of hypoglycemia) and cardiovascular event prevention. In patients with type 2 diabetes, the add-on value of combination therapy of GLP-1RA and an SGLT-2i seems promising.
AIM To investigate whether the efficacy of GLP-1RA and SGLT-2i combination observed in randomized controlled trials translates into therapeutic benefits in the Croatian population during routine clinical practice and follow-up.
METHODS We included 200 type 2 diabetes patients with poor glycemic control and analyzed the effects of treatment intensification with (1) GLP-1RA on top of SGLT-2i, (2) SGLT-2i on top of GLP-1RA compared to (3) simultaneous addition of both agents. The primary study endpoint was the proportion of participants with HbA1c < 7.0% and/or 5% bodyweight reduction. Secondary outcomes included changes in fasting plasma glucose (FPG), prandial plasma glucose, low-density lipoprotein cholesterol, estimated glomerular filtration rate (eGFR), and cardiovascular (CV) incidents assessment over a follow-up period of 12 mo.
RESULTS The majority of patients were over 65-years-old, had diabetes duration for more than 10 years. The initial body mass index was 39.41 ± 5.49 kg/m2 and HbA1c 8.32 ± 1.26%. Around half of the patients in all three groups achieved target HbA1c below 7%. A more pronounced decrease in the HbA1c seen with simultaneous SGLT-2i and GLP-1RA therapy was a result of higher baseline HbA1c and not the effect of initiating combination therapy. The number of patients achieving FPG below 7.0 mmol/L was significantly higher in the SGLT-2i group (P = 0.021), and 5% weight loss was dominantly achieved in the simultaneous therapy group (P = 0.044). A composite outcome (reduction of HbA1c below 7% (53 mmol/mol) with 5% weight loss) was achieved in 32.3% of total patients included in the study. Only 18.2% of patients attained composite outcome defined as HbA1c below 7% (53 mmol/mol) with 5% weight loss and low-density lipoprotein cholesterol < 2.5 mmol/L. There were no significant differences between treatment groups. No differences were observed regarding CV incidents or eGFR according to treatment group over a follow-up period.
CONCLUSION Combination therapy with GLP-1RA and SGLT-2i is effective in terms of metabolic control, although it remains to be determined whether simultaneous or sequential intensification is better.

Insights from VERIFY: Early Combination Therapy Provides Better Glycaemic Durability Than a Stepwise Approach in Newly Diagnosed Type 2 Diabetes. Diabetes Ther 2020; 11:2465-2476. [PMID: 32975711 PMCID: PMC7547931 DOI: 10.1007/s13300-020-00926-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Accepted: 09/10/2020] [Indexed: 12/26/2022] Open
Abstract
The treatment aims for type 2 diabetes are to prevent complications and premature mortality, and improve quality of life. Glycaemic control is central to these aims; clinical guidelines have sought to achieve this with a stepwise approach starting with lifestyle measures and metformin, adding further medications once glycated haemoglobin (HbA1c) levels rise above a predefined threshold. However, treatment intensification can be delayed when HbA1c levels increase, and HbA1c levels become inadequately controlled in many patients. Clinical inertia can result in sustained elevated levels of HbA1c; when combined with a late diagnosis, this negatively impacts patients' prognosis. Early combination therapy using medications with complementary modes of action could achieve optimal glycaemic targets and alter the course of the disease more than metformin alone. The multinational VERIFY study (clinicaltrials.gov NCT01528254) provided evidence accrued over 5 years, demonstrating the potential of early combination therapy: time to loss of glycaemic control was nearly doubled, and more than twice the number of patients experienced extended glycaemic control, with a vildagliptin-metformin combination therapy versus metformin alone. The study also showed a delay in secondary treatment failure in patients receiving the combination. Early combination therapy therefore offers a different trajectory to the stepwise approach. Translating these findings into clinical practice will require early detection and diagnosis of type 2 diabetes plus a shift in disease management. Nonetheless, the potential benefits of sustained and continuous disease control that early combination therapy offers represent the start of a new era in early diagnosis and intensive management, to achieve the treatment aims of type 2 diabetes.

Abstract
AIM To assess the efficacy and safety of combination therapy with a glucagon-like peptide-1 receptor agonist (GLP-1 RA) and a sodium-glucose co-transporter-2 inhibitor (SGLT2i) in patients with type 2 diabetes. METHODS We searched Medline, Embase, the Cochrane Library and grey literature sources up to 2 December 2019 for randomized controlled trials in adults with type 2 diabetes assessing the combination of GLP-1RA and SGLT2i, either as co-initiation therapy or as add-on to each other, against placebo or an active comparator. The primary outcome was change in HbA1c . Secondary outcomes included change in body weight, blood pressure and estimated glomerular filtration rate, and incidence of severe hypoglycaemia, all-cause mortality, cardiovascular mortality, myocardial infarction, stroke and hospitalization for heart failure. We pooled data using random effects meta-analyses. RESULTS Seven trials (1913 patients) were eligible. Compared with GLP-1RA, GLP-1RA/SGLT2i combination therapy was associated with a greater reduction in HbA1c (weighted mean difference -0.61%, 95% CI -1.09% to -0.14%, four studies), body weight (-2.59 kg, -3.68 to -1.51 kg, three studies) and systolic blood pressure (-4.13 mmHg, -7.28 to -0.99 mmHg, four studies). Compared with SGLT2i, GLP-1RA/SGLT2i combination therapy reduced HbA1c (-0.85%, -1.19% to -0.52%, six studies) and systolic blood pressure (-2.66 mmHg, -5.26 to -0.06 mmHg, six studies), but not body weight (-1.46 kg, -2.94 to 0.03 kg, five studies). After excluding data for one trial that had a considerably longer duration than the remaining studies, body weight was also reduced versus SGLT2i (-1.79 kg, -2.99 to -0.59 kg, five studies). Combination therapy did not increase the incidence of severe hypoglycaemia. Data for mortality and cardiovascular outcomes were scarce. CONCLUSIONS GLP-1RA/SGLT2i combination therapy seems to reduce HbA1c , body weight and systolic blood pressure without increasing the risk of severe hypoglycaemia compared with either GLP-1RA or SGLT2i. No conclusions can be made regarding long-term effectiveness or the effect on cardiovascular outcomes.

Abstract
AIM To determine the patterns and predictors of pharmacological treatment initiation for type 2 diabetes and whether treatment initiation is consistent with Australian clinical practice guidelines that recommend metformin monotherapy. METHODS Individuals aged 40-99 years initiating a non-insulin type 2 diabetes medication between July 2013 and February 2018 were identified from a 10% random national sample of pharmacy dispensing data. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the predictors of initiating sulfonylurea monotherapy, non-guideline monotherapy and combination therapy compared with metformin monotherapy. Predictors included age, sex, initiation year and comorbidities determined using the Rx-Risk comorbidity index. RESULTS Of the 47 860 initiators, [47% women, mean age 60.7 (sd 12.1) years], 85.8%, 4.6%, 1.9% and 7.7% received metformin monotherapy, sulfonylurea monotherapy, non-guideline monotherapy and combination therapy, respectively. Increasing age was associated with increasing odds of initiating sulfonylurea monotherapy and non-guideline monotherapy. Combination therapy initiation was less likely in women (OR 0.74, 95% CI 0.69-0.79) and people with more comorbidities (e.g. OR 0.36, 95% CI 0.29-0.44 for seven or more comorbidities vs. no comorbidities) but more likely in congestive heart failure (OR 1.42, 95% CI 1.22-1.65), cerebrovascular disease (OR 1.50, 95% CI 1.32-1.69) and dyslipidaemia (OR 1.29, 95% CI 1.19-1.40). CONCLUSION Treatment initiation in Australia is largely consistent with clinical practice guidelines, with 86% of individuals initiating metformin monotherapy. Initiation on combination therapy was more common in men and in those with fewer comorbidities.

Abstract
Introduction: There are positive aspects regarding the prescribing of fixed dose combinations (FDCs) versus prescribing the medicines separately. However, these have to be balanced against concerns including increased costs and their irrationality in some cases. Consequently, there is a need to review their value among lower- and middle-income countries (LMICs) which have the greatest prevalence of both infectious and noninfectious diseases and issues of affordability.Areas covered: Review of potential advantages, disadvantages, cost-effectiveness, and availability of FDCs in high priority disease areas in LMICs and possible initiatives to enhance the prescribing of valued FDCs and limit their use where there are concerns with their value.Expert commentary: FDCs are valued across LMICs. Advantages include potentially improved response rates, reduced adverse reactions, increased adherence rates, and reduced costs. Concerns include increased chances of drug:drug interactions, reduced effectiveness, potential for imprecise diagnoses and higher unjustified prices. Overall certain FDCs including those for malaria, tuberculosis, and hypertension are valued and listed in the country's essential medicine lists, with initiatives needed to enhance their prescribing where currently low prescribing rates. Proposed initiatives include robust clinical and economic data to address the current paucity of pharmacoeconomic data. Irrational FDCs persists in some countries which are being addressed.

Abstract
AIM To evaluate the efficacy and safety of triple therapy with low-dose dapagliflozin plus saxagliptin added to metformin in uncontrolled type 2 diabetes. MATERIALS AND METHODS This 24-week, double-blind trial (NCT02681094) randomized 883 patients (glycated haemoglobin [HbA1c] 7.5-10.0%) on metformin ≥1500 mg/d to add-on dapagliflozin 5 mg/d plus saxagliptin 5 mg/d or to add-on of either monocomponent. The primary endpoint was change in HbA1c from baseline. RESULTS Baseline mean ± SD patient characteristics were: age 56.7 ± 10.5 years; HbA1c 8.2 ± 0.9%; and diabetes duration 7.6 ± 6.1 years. Triple therapy significantly decreased HbA1c versus dual therapy (-1.03% vs. -0.63% [dapagliflozin] vs. -0.69% [saxagliptin]; P < .0001). More patients achieved HbA1c <7.0% with triple versus dual therapy (41.6% vs. 21.8% [dapagliflozin; P < .0001] vs. 29.8% [saxagliptin; P = .0018]). Triple therapy significantly decreased fasting plasma glucose (-1.5 mmol/L vs. -1.1 mmol/L [dapagliflozin; P = .0135] vs. -0.7 mmol/L [saxagliptin; P < .0001]) and body weight (-2.0 kg vs. -0.4 kg [saxagliptin; P < .0001]), and β-hydroxybutyrate levels were lower than with dapagliflozin plus metformin (mean difference -0.51; P = .0009). Urinary tract/genital infections and hypoglycaemia occurred in <5.0% and 5.8% of patients, respectively, with triple therapy. CONCLUSIONS Triple therapy with once-daily dapagliflozin 5 mg, saxagliptin 5 mg and metformin significantly improved glycaemic control versus dual therapy with either agent added to metformin in uncontrolled type 2 diabetes, and was generally well tolerated.

Abstract
Objective: Type 2 diabetes (T2D) is more common in Hispanic than non-Hispanic white (NHW) populations worldwide, and ethnicity, among other factors, may affect response to therapy. The efficacy and safety of insulin glargine 100 units/mL (iGlar) and the fixed-ratio combination of iGlar and the glucagon-like peptide 1 receptor agonist lixisenatide (iGlarLixi) was assessed in Hispanic and NHW patients with T2D from 25 countries. Methods: In this post hoc analysis, data from two 30-week randomized controlled trials comparing iGlar and iGlarLixi in patients with T2D uncontrolled on basal insulin ± oral antidiabetes drugs (OADs; LixiLan-L: NCT02058160) or uncontrolled on metformin ± OADs (LixiLan-O: NCT02058147) were evaluated. Results: Of the 1,512 patients included across trials, 301 were Hispanic and 1,211 NHW. Compared with iGlar, iGlarLixi resulted in greater reductions in glycated hemoglobin (A1C) and 2-hour postprandial glucose and a higher proportion of patients at target A1C <7.0% (<53 mmol/mol), regardless of ethnicity. Among NHWs from the LixiLan-L trial, documented symptomatic hypoglycemia (plasma glucose ≤70 mg/dL) rates were higher with iGlar compared with iGlarLixi (P = .06), whereas this trend was reversed among Hispanics (P = .07). Nevertheless, in both trials, a greater proportion of patients taking iGlarLixi than iGlar reached the composite efficacy endpoints of target A1C without hypoglycemia and target A1C without weight gain, regardless of ethnicity. Conclusion: These results indicate that iGlarLixi is a viable therapeutic option for both Hispanic and NHW patients with T2D, as it is efficacious without a significant increase in hypoglycemia, irrespective of ethnicity.

Abstract
Background: The incidence of Type 2 Diabetes Mellitus (T2DM) in Egypt is considered one of the highest in the world. Metformin and Sulfonylureas are usually prescribed together due to their efficacy and their relatively low cost. Organic cation transport 1, encoded by SLC22A1 gene, is the main transporter of metformin into hepatocytes, which is considered metformin site of action. Sulfonylureas enhance insulin release from pancreatic B-cells through binding to sulfonylurea receptor 1, encoded by ABCC8 gene. Single nucleotide polymorphisms in the SLC22A1 and ABCC8 genes might affect the response of each drug. Aims: To investigate the influence of SLC22A1 rs622342 (A>C) and ABCC8 rs757110 (A>C) genetic variants on the efficacy of metformin and glimepiride combination therapy in Egyptian T2DM patients. Methods: Observational cross-sectional study in which patients receiving metformin and glimepiride combination therapy for at least 6 months were included for genotyping and classified into either responders or non-responders, based on their HbA1C level. Results: A total of 127 patients were included and genotyped. They were divided into 93 responders (HbA1C<7%) and 34 non-responders (HbA1C≥7%). Minor allele frequencies for rs622342 and rs757110 were 0.189 and 0.271, respectively. Only SLC22A1 rs622342 variant was found to be associated with the response of combination therapy, in which AA alleles carriers were 2.7-times more responsive to metformin than C allele carriers (Recessive model, odds ratio = 2.718, p = 0.025, 95% CI = 1.112–6.385). Conclusion: Genotyping of rs622342 can be useful in predicting the response to metformin in combination therapy in Egyptian T2DM patients.

Abstract
INTRODUCTION iGlarLixi is a titratable, fixed-ratio combination of insulin glargine (100 units/mL) and lixisenatide (33 μg/mL). This review evaluates the overall safety and adverse event (AE) profile of iGlarLixi in patients with type 2 diabetes. METHODS We collated patient-level data from the phase 2 LixiLan proof-of-concept trial and the phase 3 LixiLan-L (insulin-experienced patients) and LixiLan-O (insulin-naïve patients) trials to evaluate AEs associated with iGlarLixi. We also describe data from the ELIXA study to examine pancreatitis and pancreatic cancer, and the ELIXA and ORIGIN studies for cardiovascular safety data. RESULTS Patients treated with iGlarLixi had improved glycemic control with a similar incidence of documented symptomatic hypoglycemia (plasma glucose ≤ 70 mg/dL) compared with iGlar. Incidence of severe hypoglycemia (an event requiring third-party assistance) was low in all treatment arms in both LixiLan-L and LixiLan-O. Rates of gastrointestinal AEs in patients treated with iGlarLixi tended to be lower compared with lixisenatide alone, but higher than those treated with iGlar alone. Gastrointestinal AEs were generally mild to moderate in intensity and transient. Antibodies formed in response to iGlarLixi did not have any significant clinical impact, with similar safety observed for antibody-positive and antibody-negative populations. Rates of allergic reactions, malignancy, renal impairment, and cardiovascular events were low and comparable between treatment groups. Older age (≥ 65 years) and gender did not affect efficacy or safety. CONCLUSION iGlarLixi has a safety profile that is consistent with that of its two active components insulin glargine and lixisenatide, with no signals for pancreatitis or thyroid C cell tumors, and no black-box warning for iGlarLixi. There were no unexpected safety findings; iGlarLixi had beneficial effects on glycemic control, with no increased risk of hypoglycemia, despite a greater glycated hemoglobin A1c reduction. In addition, there were also fewer gastrointestinal AEs associated with iGlarLixi compared with lixisenatide alone. FUNDING Sanofi US Inc.

Combination Therapy with an SGLT2 Inhibitor as Initial Treatment for Type 2 Diabetes: A Systematic Review and Meta-Analysis. J Clin Med 2019; 8:jcm8010045. [PMID: 30621212 PMCID: PMC6352265 DOI: 10.3390/jcm8010045] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Revised: 12/29/2018] [Accepted: 12/29/2018] [Indexed: 02/06/2023] Open
Abstract
Background: Guidelines differ with regard to indications for initial combination pharmacotherapy for type 2 diabetes. Aims: To compare the efficacy and safety of (i) sodium-glucose cotransporter 2 (SGLT2) inhibitor combination therapy in treatment-naïve type 2 diabetes adults; (ii) initial high and low dose SGLT2 inhibitor combination therapy. Methods: PubMed, Embase and Cochrane Library were searched for randomised controlled trials (RCTs) of initial SGLT2 combination therapy. Mean difference (MD) for changes from baseline (HbA1c, weight, blood pressure) after 24–26 weeks of treatment and relative risks (RR, safety) were calculated using a random-effects model. Risk of bias and quality of evidence was assessed. Results: In 4 RCTs (n = 3749) there was moderate quality evidence that SGLT2 inhibitor/metformin combination therapy resulted in a greater reduction in HbA1c (MD (95% CI); −0.55% (−0.67, −0.43)) and weight (−2.00 kg (−2.34, −1.66)) compared with metformin monotherapy, and a greater reduction in HbA1c (−0.59% (−0.72, −0.46)) and weight (−0.57 kg (−0.89, −0.25)) compared with SGLT2 inhibitor monotherapy. The high dose SGLT2 inhibitor/metformin combination resulted in a similar HbA1c but greater weight reduction; −0.47 kg (−0.88, −0.06) than the low dose combination therapy. The RR of genital infection with combination therapy was 2.22 (95% CI 1.33, 3.72) and 0.69 (95% CI 0.50, 0.96) compared with metformin and SGLT2 inhibitor monotherapy, respectively. The RR of diarrhoea was 2.23 (95% CI 1.46, 3.40) with combination therapy compared with SGLT2 inhibitor monotherapy. Conclusions: Initial SGLT2 inhibitor/metformin combination therapy has glycaemic and weight benefits compared with either agent alone and appears relatively safe. High dose SGLT2 inhibitor/metformin combination therapy appears to have modest weight, but no glycaemic benefits compared with the low dose combination therapy.
