The Effect of Sodium-Glucose Cotransporter Inhibitors on Renal Function as Adjunctive to Insulin in Adults with Type 1 Diabetes: An Updated Multilevel Meta-analysis of Randomized Controlled Trials. Diabetes Ther 2024; 15:521-532. [PMID: 38180713 PMCID: PMC10838855 DOI: 10.1007/s13300-023-01523-0] [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: 11/19/2023] [Accepted: 12/14/2023] [Indexed: 01/06/2024] Open
Abstract
INTRODUCTION This systematic review aimed to summarize the existing evidence from published randomized controlled trials (RCTs) on the impact of sodium-glucose cotransporter (SGLT) inhibitors on albuminuria levels and renal function in patients with type 1 diabetes mellitus (T1D). METHODS The literature search was performed through Medline (via PubMed), Cochrane Library, and Scopus until November 11, 2023. Double-independent study selection, data extraction, and quality assessment were performed. Evidence was pooled with three-level mixed-effects meta-analysis. RESULTS In total, 5221 participants with T1D among 11 RCTs were analyzed. All RCTs had low risk of bias according to the Cochrane Collaboration tool (RoB 2). SGLT inhibitors were associated with a significantly greater reduction in urine albumin-to-creatinine ratio (UACR) compared to controls (MD = - 23.13%; 95% CI = [- 33.69, - 12.57]; P < 0.001; level of evidence high). On the basis of subgroup analysis, this effect was consistent across all available SGLT inhibitors, irrespective of the dosage. Finally, a neutral class effect was observed on the estimated glomerular filtration rate (eGFR, MD = - 1.03 mL/min/1.73 m2; 95% CI = [- 2.26, 0.19]; P = 0.1; level of evidence moderate). Only empagliflozin was associated with a significant reduction in eGFR compared to placebo (MD = - 2.23 mL/min/1.73 m2; 95% CI = [- 3.62, - 0.84]; P = 0.002). CONCLUSION Our findings suggest that adjunctive therapy with SGLT inhibitors results in a significant reduction in albuminuria, while their use is associated with a neutral effect on creatinine clearance, as a measure of renal function. Future renal outcome trials are needed to assess SGLT inhibitors' role in the pharmacological armamentarium against diabetic nephropathy in T1D.

[PMID: 37980217 DOI: 10.1016/j.pcd.2023.10.010] [Citation(s) in RCA: 1] [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: 07/06/2023] [Revised: 10/08/2023] [Accepted: 10/22/2023] [Indexed: 11/20/2023]
Abstract
AIMS Sodium glucose cotransporter2 (SGLT2) inhibitors are controversial in the treatment of type 1 diabetes mellitus (T1DM). This study is a systematic evaluation of the safety of SGLT2 inhibitors usage in T1DM. METHODS Comprehensive literature search in six databases from inception to September 2022. Randomized controlled trials (RCTs) of T1DM treated with SGLT2 inhibitor vs. placebo were included. Data were extracted from the literature that met the inclusion criteria. After quality evaluation by the Cochrane risk bias assessment tool, meta-analysis was performed using Revman 5.4 and Stata 17.1. RESULTS The study consisted of 16 RCTs with 7192 patients. The results indicated that SGLT2inhibitors reduce glycated hemoglobin (HbA1c, Mean difference (MD)- 0.29%, P < 0.05), fasting plasma glucose (FPG, MD-0.85 mmol/L, P < 0.05), mean amplitude of glucose excursions (MAGE, 15.75 mg/dL, P < 0.05), body weight (MD-3.49 kg, P < 0.05), and total insulin dosage (MD-7.14 IU/day, P < 0.05). Furthermore, cautious SGLT2 inhibitors did not induce the risk of hypoglycemia (RR1.00, P = 0.86), urinary tract infections (RR1.02, P = 0.085), and diarrhea (RR1.34, P = 0.523). CONCLUSION Based on this meta-analysis, SGLT22 inhibitors reduce insulin dosage without increasing the risk of hypoglycemia and diabetic ketoacidosis for type 1 diabetes mellitus in 1month.

Glucagon-Like Peptide 1 Analogues as Adjunctive Therapy for Patients With Type 1 Diabetes: An Updated Systematic Review and Meta-analysis. J Clin Endocrinol Metab 2023; 109:279-292. [PMID: 37561012 DOI: 10.1210/clinem/dgad471] [Citation(s) in RCA: 1] [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: 06/02/2023] [Revised: 07/24/2023] [Accepted: 08/09/2023] [Indexed: 08/11/2023]
Abstract
CONTEXT Concomitant obesity is common among patients with type 1 diabetes mellitus (T1DM), yet adjunctive therapy options are scarce. OBJECTIVE We assess the efficacy and adverse outcomes of glucagon-like peptide 1 (GLP-1) analogues when used as adjunctive therapy for T1DM. METHOD PubMed, EMBASE, Cochrane Central, and Scopus databases were searched for randomized controlled trials up to December 2022. Efficacy outcomes were A1c level, body weight, and total daily insulin (TDI) after ≥12 weeks of GLP-1 therapy. We also assessed 12 different adverse outcomes. Subgroup analysis was done for newly diagnosed or C-peptide positive (C-pos) patients. We report the certainty of evidence based on the GRADE assessment tool. RESULTS A total of 24 studies using 4 different GLP-1 analogues with a total of 3377 patients were included. Liraglutide had the most substantial evidence with effect sizes on A1c (-0.09%/mg), weight (-2.2 kg/mg), and TDI (-4.32 IU/mg). Liraglutide dose was the greatest predictor of greater average weight loss and TDI decrease but was associated with higher odds of nausea (OR 6.5; 95% CI, 5.0-8.4) and ketosis (OR 1.8; 95% CI, 1.1-2.8). Odds of severe (OR 0.67; 95% CI, 0.43-1.04) or symptomatic hypoglycemia (OR 0.89; 95% CI, 0.53-1.51) were not significantly elevated. Among C-pos patients, greater A1c decrease (-0.51% vs -0.28%) but similar weight loss and TDI were seen. Effect sizes for exenatide were similar, but studies had higher risk of bias and safety data were sparse. CONCLUSION Our meta-analysis supports therapeutic benefits of liraglutide for patients with T1DM mainly for weight loss and insulin dose reduction. Newly diagnosed or C-pos patients do not appear to experience greater weight loss benefits.

Abstract
SGLT2i (sodium glucose transporter type 2 inhibitors) are pharmacological agents that act by inhibiting the SGLT2, by reducing the renal plasma glucose threshold and inducing glycosuria, resulting in a blood glucose lowering effect. In recent years, studies demonstrating some additional positive effects of SGLT2i also in the treatment of T1D have increased progressively. The SGLT2i dapagliflozin and sotagliflozin have been temporarily licensed for use by the European Medical Agency (EMA) as an adjunct to insulin therapy in adults with T1D with a body mass index of 27 kg/m2 or higher. However, in the meantime, the US Food and Drug Administration (FDA) Endocrinologic and Metabolic Drugs Advisory Committee was divided, citing concerns about the main side effects of SGLT2i, especially diabetic ketoacidosis (DKA). The aim of this manuscript was to conduct an update on current evidence and recommendations of the reported use of SGLT2i in the treatment of T1D in humans. Preclinical studies, clinical trial and real world data suggest benefits in glycaemia control and nefro-cardiovascular protection, even though several studies have documented an important increase in the risk of DKA, a serious and life-threatening adverse event of these agents. SGLT2i potentially addresses some of the unmet needs associated with T1D by improving glycaemic control with weight loss and without increasing hypoglycemia, by reducing glycaemic variability. However, due to side effects, EMA recommendation for SGLT2 use on T1D was withdrawn. Further studies will be needed to determine the safety of this therapy in T1D and to define the type of patient who can benefit most from these medications.

Abstract
Background The treatment duration of insulin-sodium-glucose co-transporter inhibitors (SGLTis) co-treatment of type 1 diabetes mellitus (T1DM) patients in randomized controlled trials (RCTs) varies by 1-52 weeks. Henceforth, treatment duration-wise, we compared the following insulin-treatment adjuncts- mega- versus low-dose SGLTis, SGLTis versus placebo, and different SGLTi dosages. Method Double-blinded RCTs reporting the above were searched (using terms like insulin-dependent, "juvenile-onset diabetes," and "sodium glucose cotransport*") in the PubMed, Embase, and Scopus databases and appraised using a Cochrane tool. The risks across different SGLTi-dosages were compared using network meta-analysis. Random-effect pairwise meta-analysis was performed for the remaining harm juxtapositions. Meta-analyses were performed for the following treatment durations- < 4 weeks, 4 to < 24 weeks, and ≥ 24 weeks. For meta-analysis and certainty of evidence assessment, we used the Stata statistical software and the GRADE method, respectively. Results A total of 15 (low risks of bias) studies sourcing data from about 7,330 T1DM patients were reviewed. Meta-analysis findings of ≥ 24 weeks long trials were- a. SGLTi-insulin co-treatment increased the genital infection (GI) (RR: 3.51; 95% CI: 2.59, 4.77), diabetic ketoacidosis (DKA) and (RR: 3.25; 95% CI:1.29, 8.16), and serious side effects (RR: 1.43; 95% CI: 1.05, 1.94) risk. b. SGLT2i-insulin increased the GI risk (RR: 3.77; 95% CI: 2.31, 6.16; high-quality evidence). c. Sotagliflozin-insulin increased the GI (RR: 3.36; 95% CI: 2.28, 4.96) and DKA (RR: 6.69; 95% CI: 2.75, 16.32) risk (both high-quality evidence). Compared to low-dose, megadose SGLTi treatment for 4 to < 24 weeks increased the GI risk. The remaining analyses were not statistically significantly different. Conclusion On moderate to long-term treatment (24-52 weeks) of T1DM patients, insulin-SGLT2i co-treatment was associated with GI risk, and insulin-sotagliflozin co-treatment was associated with DKA and GI risk.

Abstract
Background: To assess the efficacy and safety of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) used as an adjunct to insulin therapy in adults with type 1 diabetes. Methods: A search of electronic databases (Medline, Embase, and the Cochrane Central Register of Controlled Trials) from 1 January 1950 to 23 May 2021 was conducted to find randomized controlled trials. The primary outcome was the change in HbA1c. Eight efficacy and six safety secondary endpoints were evaluated via meta-analysis. Weighted mean difference (WMD) and odds ratio (OR), alongside 95% confidence interval (CI), were calculated using the random effects model. Results: Among 1,379 candidate studies, 11 trials comprising 2,856 participants satisfied the inclusion criteria. Overall, GLP-1 RA adjunctive therapy reduced HbA1c by -0.21% (95% CI, -0.33 to -0.10), weight by -4.04 kg (-4.8 to -3.27), systolic pressure by -2.57 mmHg (-4.11 to -1.03), and diastolic blood pressure by -1.02 mmHg (-1.99 to -0.06). In addition, there was a decrease in prandial insulin dose (WMD, -4.23 IU; 95% CI, -5.26 to -3.20), basal insulin dose (-2.40 IU; -3.93 to -0.87), and total insulin dose (-5.73 IU; -10.61 to -0.86). Moreover, GLP-1 RAs did not increase the incidence of severe hypoglycemia, diabetic ketoacidosis, or severe adverse events. However, GLP-1 RAs increased the incidence of gastrointestinal adverse events (OR, 2.96; 95% CI, 2.33-3.77). Conclusion: Our meta-analysis of randomized clinical trials suggests moderate beneficial effects of GLP-1 RAs on the metabolic profile in patients with type 1 diabetes, without an increased risk of serious adverse events.

Abstract
Dapagliflozin has been used to treat patients with type 1 diabetes mellitus; however, the actual drug efficacy of dapagliflozin on glycated hemoglobin (HbA1c) and whether there is a rebound from dapagliflozin efficacy on HbA1c remain unknown. The present study aimed to explore the actual therapeutic effect and rebound situation of dapagliflozin on HbA1c in type 1 diabetes mellitus patients. A total of 1,594 type 1 diabetes mellitus patients were enrolled for analysis using a non-linear mixed effect model from randomized controlled trials from published literature works including two 5 mg/day dapagliflozin dosage groups and three 10 mg/day dapagliflozin dosage groups. The change rate of HbA1c from a baseline value was chosen as a dapagliflozin pharmacodynamic evaluation index. After deducting control group effects, the therapeutic effect of 5 and 10 mg/day dapagliflozin on HbA1c in type 1 diabetes mellitus patients had no significant difference. In addition, the actual maximal efficacy (AEmax) of dapagliflozin on HbA1c was -6.24% at week 9. When it reached the AEmax, the dapagliflozin pharmacodynamic rebound on HbA1c occurred, and when the treatment was continued for 0.5 and 1 year, the actual efficacies were -4.70% (75% AEmax) and -3.27% (52% AEmax), respectively. This was the first time to clarify the actual therapeutic effect and rebound situation of dapagliflozin on HbA1c in type 1 diabetes mellitus patients, providing a reference value for clinical practices.

Abstract
INTRODUCTION There have been many recent advances in the treatment of type 1 diabetes (T1D) including in insulin formulations, continuous glucose monitoring (CGM) technology and automated insulin delivery. However, long-term optimal glycemic control is still only achieved in a minority. AREAS COVERED Adjunct therapy - the use of therapeutic agents other than insulin - is one strategy aimed at improving outcomes. An ideal adjunct agent would improve glycemic control, reduce weight (or weight gain), reduce insulin requirement and prevent complications (e.g. cardiorenal) without increasing hypoglycemia. The amylin analogue pramlintide has been licensed in the USA, while the sodium glucose co-transporter-2 inhibitor (SGLT2i) dapagliflozin, was briefly (2019 - 2021) licensed for type 1 diabetes in Europe and the UK. However, other agents from the type 2 diabetes (T2D) arena including metformin, other SGLT2is, glucagon-like peptide-1 receptor agonists (GLP-1RA) and dipeptidyl peptidase-IV (DPP-4) inhibitors have been investigated. EXPERT OPINION As evidence emerges for cardiorenal protection by SGLT2is and GLP-1RAs in T2D, it has become increasingly important to know whether people with T1D can also benefit. Here, we review recent trials of adjunct agents in T1D and discuss the efficacy and safety of these agents (alone and in combination) in an era in which continuous glucose monitoring is becoming standard of care.

Abstract
The current study aims to assess the protective effects of dapagliflozin (Dapa; a sodium-glucose cotransporter-2 inhibitor) and/or liraglutide (Lira; a glucagon-like peptide 1 agonist) in an experimental model of diabetic cardiomyopathy (DCM). A single dose of streptozotocin (STZ) was administrated to male Sprague-Dawley rats by intraperitoneal injection at a dose of 50 mg/kg to induce diabetes mellitus (DM). Dapa (1 mg/kg, orally), Lira (0.4 mg/kg, s.c.), and Dapa-Lira combination were administrated for 8 weeks once-daily. Blood samples were evaluated for glucose level and biochemical markers of cardiac functions. Cardiac tissue was dissected and assessed for redox homeostasis (malondialdehyde (MDA), glutathione (GSH), and catalase (CAT)), pro-inflammatory mediators (NF-κB and tumor necrosis factor-α (TNF-α)), and apoptotic effectors (caspase-3). Moreover, the effect of treatments on the cardiac cellular structure was studied. Dapa and/or Lira administration resulted in significant improvement of biochemical indices of cardiac function. Additionally, all treatment groups demonstrated restoration of oxidant/antioxidant balance. Moreover, inflammation and apoptosis key elements were markedly downregulated in cardiac tissue. Also, histological studies demonstrated attenuation of diabetes-induced cardiac tissue injury. Interestingly, Dapa-Lira combination treatment produced a more favorable protective effect as compared to a single treatment. These data demonstrated that Dapa, Lira, and their combination therapy could be useful in protection against DM-accompanied cardiac tissue injury, shedding the light on their possible utilization as adjuvant therapy for the management of DM patients.

Wang DD, He SM, Han Y, Wang TY, Wang YM. Quantifying the relationship between dapagliflozin and loss of weight in type 1 diabetes mellitus patients. J Clin Pharm Ther 2021; 47:237-242. [PMID: 34755375 DOI: 10.1111/jcpt.13572] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 10/09/2021] [Accepted: 11/01/2021] [Indexed: 12/25/2022]
Abstract
WHAT IS KNOWN AND OBJECTIVES Dapagliflozin was the first oral treatment approved in type 1 diabetes mellitus (T1DM) patients, simultaneously improving body weight. However, the time course and dose effect of dapagliflozin on loss of weight in T1DM patients was still unknown. The present study aimed to investigate quantitative relationship between dapagliflozin and loss of weight in T1DM patients based on Model-based Meta-analysis. METHODS Five dapagliflozin dosage groups, two of them were 5 mg/day and three of them were 10 mg/day, 1612 T1DM patients were analysed with maximal effect (Emax ) model, and evaluation index was change rate of body weight from baseline value. RESULTS In these T1DM patients, dosages were not incorporated into model, indicating no significant dose-response relationship between 5 and 10 mg/day affecting loss of weight. Emax and the treatment duration to reach half of the maximal effects (ET50 ) of dapagliflozin influencing loss of weight in T1DM patients were -4.9% and 10.4 weeks, and the duration to achieve 25%, 50%, 75%, and 80% (plateau) of Emax were 3.5, 10.4, 31.2, and 41.6 weeks. WHAT IS NEW AND CONCLUSIONS It was the first time to explore quantitative relationship between dapagliflozin and loss of weight in T1DM patients. To achieve the plateau period in loss of weight, 5 mg/day dapagliflozin was required for at least 41.6 weeks.

Abstract
Closed-loop insulin delivery systems are fast becoming the standard of care in the management of type 1 diabetes and have led to significant improvements in diabetes management. Nevertheless, there is still room for improvement for the closed-loop systems to optimize treatment and meet target glycemic control. Adjunct treatments have been introduced as an alternative method to insulin-only treatment methods to overcome diabetes treatment challenges and improve clinical and patient reported outcomes during closed-loop treatment. The adjunct treatment agents mostly consist of medications that are already approved for type 2 diabetes treatment and aim to complete the missing physiologic factors, such as the entero-endocrine system, that regulate glycemia in addition to insulin. This paper will review many of these adjunct therapies, including the basic mechanisms of action, potential benefits, side effects, and the evidence supporting their use during closed-loop treatment.

Abstract
Increased glucagon level was hypothesized to participate in the ketoacidosis associated with sodium-glucose co-transporter 2 inhibitors (SGLT2i) treatment. However, the effect of SGLT2i on glucagon remains controversial. Hence, we conducted this meta-analysis to assess the overall effect of SGLT2i treatment on plasma fasting glucagon level in patients with diabetes. PubMed/MEDLINE, Embase, and Cochrane databases were searched for studies published before August 2020. Clinical trials in patients with type 1 diabetes mellitus and type 2 diabetes mellitus with reports of glucagon changes before and after SGLT2i intervention were included. Eligible trials were analyzed by fixed-effect model, random effect model, and meta-regression analysis accordingly. In total, ten trials were included in this meta-analysis. Compared with the non-SGLT2i treatment group, SGLT2i treatment resulted in increased plasma fasting glucagon levels with significance (WMD, 8.35 pg/ml; 95% CI, 2.17-14.54 pg/ml, P<0.01) in patients with diabetes mellitus. Besides, when compared with non-SGLT2i control group, the insulin level decreased (WMD, -2.78 μU/ml; 95% CI, -5.11 to -0.46 μU/ml, P = 0.02) and ketone body level increased (WMD, 0.17 mmol/l; 95% CI, 0.09-0.25 mmol/l, P<0.01) in patients with type 2 diabetes. In conclusion, our result indicated SGLT2i intervention would increase the plasma fasting glucagon level in patients with diabetes mellitus. The increase in plasma fasting glucagon level may be associated with reduced insulin level. The increased glucagon-insulin ratio after the use of SGLT2i may make diabetic patients susceptible to ketosis.

Abstract
OBJECTIVES Dapagliflozin (Dapa) could potentially be used to treat type 1 diabetes mellitus. We tested the hypothesis that it would influence blood lipid levels and visceral fat accumulation in a rodent diabetic model. METHODS We used three groups of male Wistar rats: Controls, streptozotocin (STZ)-treated rats and STZ-treated orally with Dapa (STZ+Dapa), 10 mg/kg/day for six weeks. Blood glucose and serum lipids levels were determined. Plasma levels of lipases (hormone-sensitive lipase, HSL and lipoprotein lipase, LPL), adipokines (leptin and adiponectin) and proinflammatory cytokines [tumour necrosis factor-alpha (TNFα) and interleukin-6 (IL-6)] were determined by ELISA assays. mRNA levels in the perirenal fat were determined by real-time PCR. KEY FINDINGS Dapa suppressed STZ-related hyperglycemia by 20% (P < 0.05) and increased serum HDL when compared to the controls and the STZ-only treated rats (both P < 0.05). STZ treatment caused elevations of other serum lipids that were resistant to Dapa treatment. Dapa treatment also increased both plasma and visceral fat mRNA levels of leptin, LPL and IL-6, while decreasing plasma and fat expressions of HSL and TNFα compared to the STZ-only treated rats (all P < 0.05). CONCLUSIONS Our results suggest that Dapa, in addition to its antidiabetic effect, also influences the function of adipose tissue which could be beneficial in the treatment of diabetes.

Abstract
AIMS/INTRODUCTION Several clinical trials reported the effects of sodium-glucose cotransporter (SGLT) inhibitors in type 1 diabetes patients. This meta-analysis aimed to assess the efficacy and safety of SGLT inhibitors in type 1 diabetes patients. MATERIALS AND METHODS Relevant studies were identified in the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure and Wan Fang databases through 1 April 2020. Differences were expressed as the 95% confidence interval (CI) or weighted mean difference (WMD) for continuous outcomes, and risk ratio (RR) for discontinuous outcomes. RESULTS A total of 13 RCTs with 7,962 cases were included. SGLT inhibitors reduced the fasting plasma glucose level (WMD -1.320 mmol/L, 95% CI -1.609 to -1.031, P < 0.001), glycated hemoglobin level (WMD -0.386%, 95% CI -0.431 to -0.342, P < 0.001) and daily total insulin dose (WMD -5.403, 95% CI -7.218 to -3.859, P < 0.001). However, higher risks of diabetic ketoacidosis (RR 5.042, 95% CI 3.160-8.046, P < 0.001), urinary tract infections (RR 1.259, 95% CI 1.034-1.533,P = 0.022) and genital infections (RR 2.995, 95% CI 1.953-4.594, P < 0.001) were associated with SGLT inhibitors, but SGLT inhibitors did not increase the hypoglycemia risk (RR 0.980, 95% CI 0.840-1.144,P = 0.799). In subgroup analysis, with a significant reduction of fasting plasma glucose, glycated hemoglobin and daily insulin doses, SGLT1/2 inhibitor did not increase genitourinary tract infections compared with a placebo. CONCLUSIONS SGLT2 and SGLT1/2 inhibitors can improve glycemic control in patients with type 1 diabetes.

Abstract
Introduction The efficacy of dapagliflozin for type 1 diabetes remains controversial. We conduct a systematic review and meta-analysis to explore the treatment efficacy of dapagliflozin versus placebo in patients with type 1 diabetes. Methods We have searched PubMed, EMbase, Web of science, EBSCO and Cochrane library databases through May 2019 for randomized controlled trials (RCTs) assessing the effect of dapagliflozin versus placebo for type 1 diabetes. This meta-analysis is performed using the random-effect model. Results Six RCTs are included in the meta-analysis. Overall, compared with control group for type 1 diabetes, dapagliflozin treatment shows favorable impact on glycated hemoglobin HbA1c (standard mean difference SMD=-3.93; 95% confidence interval CI =-4.44 to -3.48; P<0.00001), HbA1c reduction of ≥0.5% (risk ratio RR=1.98; 95% CI=1.65 to 2.39; P<0.00001), and fasting plasma glucose FPG (SMD=-0.93; 95% CI=-1.77 to -0.10; P=0.03). There is no statistical difference of hypoglycemia (RR=1.09; 95% CI=0.66 to 1.79; P=0.75) or adverse events (RR=1.07; 95% CI=0.96 to 1.20; P=0.20) between two groups, but the incidence of ketone-related events is higher than those in control group (RR=0.28; 95% CI=3.96 to 11.52; P=0.01). Conclusions Dapagliflozin treatment benefits to reduce HbA1c and FPG for type 1 diabetes.

Abstract
The growing proportion of type 1 diabetes mellitus (T1DM) patients with clinical features of insulin resistance (IR) has led to the description of a distinctive T1DM subgroup, still unrecognised by current guidelines, called double diabetes, assumingly associated with poorer metabolic phenotype and increased risk of micro- and macrovascular complications. The main goal of identifying double diabetes, estimated to be present in up to half of T1DM patients, is timely implementation of appropriate therapeutic interventions to reduce the increased risk of chronic complications and other adverse metabolic traits associated with this condition. Proposed diagnostic criteria are largely divided into three different groups: family history of type 2 diabetes mellitus (T2DM), obesity/metabolic syndrome, and IR. Estimated glucose disposal rate may prove the most reliable marker of double diabetes. In addition to general measures (diet, physical activity, antihypertensive, and lipid-lowering medications, etc.) and development of new insulin preparations with more hepatic action, double diabetes patients may derive more benefit from agents developed for T2DM. Indeed, such potentially promising agents include glucagon-like peptide-1 receptor agonists, sodium-glucose contrasporter-2 inhibitors, and their combination. We are now awaiting long-term trials assessing metabolic and vascular benefits of these medications in double diabetes.

Abstract
Sodium glucose cotransporter-2 (SGLT2) is a sodium-dependent glucose transporter responsible for renal absorption of glucose. Dapagliflozin is an SGLT2 inhibitor used in patients with type 1 diabetes to promote urinary glucose excretion, but to date, randomized controlled trials (RCTs) to evaluate the effect of this drug in this disease have not been systematically evaluated. Therefore, the aim of the present study was to evaluate the efficacy and safety of dapagliflozin, as an adjuvant therapy to insulin, in the treatment of type 1 diabetes mellitus through a systematic review and meta-analysis. The Cochrane Library Database, Medline and Embase databases were used to search articles published between January 1st 2004 and February 5th 2020 with no language restrictions relating to RCTs. After extracting the data, the quality of the RCTs was evaluated and the data were statistically analyzed. A total of 4 RCTs with 1,691 participants were included. Dapagliflozin resulted in decreased glycosylated hemoglobin A1c (0.40-0.45%), body weight (2.52-3.85 kg), mean daily glucose (0.76-0.99 mmol/l) and mean amplitude of glucose excursion (0.54-1.07 mmol/l; all with P<0.00001) compared to placebo. Subgroup analysis by dose indicated no significant difference in all efficacy outcome indicators between dapagliflozin at 5 and at 10 mg (P>0.1). Compared with placebo, the use of dapagliflozin in patients with type 1 diabetes increased the risk of adverse events and serious adverse events (P<0.05), but did not increase the risks of infection, diabetic ketoacidosis (DKA) and discontinuation due to adverse events. Analysis by dose group suggested that no significant difference in all safety outcome indicators between dapagliflozin at 5 and at 10 mg (P>0.1). In conclusion, dapagliflozin had a significant effect on type 1 diabetes. However, the use of dapagliflozin significantly increased the incidence of adverse events and serious adverse events compared with placebo. Dapagliflozin-assisted short-term (24 weeks) insulin therapy for type 1 diabetes did not increase the risk of DKA but additional high-quality studies are required to determine its long-term efficacy and safety.

Abstract
AIM To systematically review the effects of pharmacological and lifestyle interventions on body weight as a secondary outcome in people with type 1 diabetes. METHODS The Ovid Medline, Embase and Cochrane Library databases were searched for relevant pharmacological (glucagon-like peptide-1 [GLP-1] receptor agonist, sodium-glucose co-transporter-2 [SGLT-2] inhibitor, dipeptidyl peptidase-4 [DPP-4] inhibitor and metformin) and lifestyle intervention studies (diet and exercise) for adults with type 1 diabetes reporting body weight change and HbA1c published from January 2000 to May 2020. Meta-analyses were performed for 16 randomized controlled trials (RCTs). RESULTS Thirty-three RCTs (n = 9344 participants), 26 pharmacological (on average 43.9 years, 83.1 kg, HbA1c 8.1%; 55.8% male) and seven lifestyle-based interventions (on average 37.0 years, 85.0 kg, HbA1c 8.1%; 84.6% male), were analysed. The GLP-1 receptor agonist liraglutide 0.6 mg (mean difference [MD]: -2.22 kg [95% CI: -2.55 to -1.90]), 1.2 mg (MD: -3.74 kg [95% CI: -4.16 to -3.33]) and 1.8 mg (MD: -4.85 kg [95% CI: -5.29 to -4.41]), and the SGLT-2 inhibitors empagliflozin 2.5 mg (MD: -1.47 kg [95% CI: -2.23 to -0.71]), 10 mg (MD: -2.77 kg [95% CI: -3.24 to -2.31]) and 25 mg (MD: -3.06 kg [95% CI: -3.57 to -2.55]) and sotagliflozin 200 mg (MD: -2.40 kg [95% CI: -2.87 to -1.94]) and 400 mg (MD: -3.23 [95% CI: -3.73 to -2.72]) were associated with significant reductions in body weight. No significant effect on body weight was found for DPP-4 inhibitors, other GLP-1-receptor agonists, metformin, or for lifestyle interventions (i.e. exercise and diet). CONCLUSIONS In people with type 1 diabetes, several adjuvant pharmacological interventions showed weight reduction as a secondary outcome. Future studies in overweight people with type 1 diabetes are needed to establish whether the lifestyle and pharmacological interventions reviewed here have potential as components of complex interventions aimed at body weight reduction as a primary outcome.

Abstract
Dapagliflozin (SGLT-2 inhibitor) and sotagliflozin (SGLT1/2 inhibitor) are two of the drugs of SGLT inhibitor class which have been recommended by the National Institute for Health and Care Excellence (NICE) in people with type 1 diabetes with BMI ≥27 kg/m2 . Dapagliflozin is licensed in the UK for use in the NHS while sotagliflozin may be available in future. These and possibly other SGLT inhibitors may be increasingly used in people with type 1 diabetes as new licences are obtained. These drugs have the potential to improve glycaemic control in people with type 1 diabetes with the added benefit of weight loss, better control of blood pressure and more time in optimal glucose range. However, SGLT inhibitors are associated with a higher incidence of diabetic ketoacidosis without significant hyperglycaemia. The present ABCD/Diabetes UK joint updated position statement is to guide people with type 1 diabetes and clinicians using these drugs help mitigate this risk and other potential complications. Particularly, caution needs to be exercised in people who are at risk of diabetic ketoacidosis due to low calorie diets, illnesses, injuries, starvation, excessive exercise, excessive alcohol consumption and reduced insulin administration among other precipitating factors for diabetic ketoacidosis.

Abu-Zaid A, Altowairqi AK, Dissanayaka T, Oganesyan A, Bhagavathul AS, Alhabeeb H, Baradhwan A, Alomar S, Tom S. A systematic review and dose-response meta-analysis on the efficacy of dapagliflozin in patients with type 1 diabetes mellitus. Pharmacol Res 2021; 165:105456. [PMID: 33515709 DOI: 10.1016/j.phrs.2021.105456] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 12/06/2020] [Accepted: 01/21/2021] [Indexed: 01/10/2023]
Abstract
Formulation of insulin analogs and its delivery are developed in over recent years but glycemic control in most patients with type-1 diabetes mellitus (DM) is not adequate yet. The aim of this meta-analysis is to evaluate the efficacy of dapagliflozin in patients with type-1 DM. The MEDLINE/PubMed, Scopus, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science databases were searched up to Aug 2020 to identify the potential literature. Random-effects model (DerSimonian and Laird method) was used to estimate the pooled effect size as weighted mean difference (WMD) with 95 % confidence interval (CI). Five randomized placebo-controlled trials with 11 arms were included in the quantitative analysis. The pooled results suggested a significant reduction in glycated hemoglobin A1C (HbA1C; WMD: -0.36 %, 95 % CI: -0.55, -0.18), body weight (WMD: -4.02 kg, 95 % CI: -4.78, -3.25), and total daily insulin dose (TDID; WMD: -10.36 %, 95 % CI: -13.42, -7.29), as well as an increase in 24-h urinary glucose excretion (24-h UGE; WMD: 90.02 g/24-h, 95 % CI: 72.96, 107.09) in dapagliflozin group compared to control group. Dose of dapagliflozin had a significant effect on body weight reduction (Coef = -3.7, p = 0.01) and 24-h UGE (coef = 0.85, p = 0.005). Pooled results of this meta-analysis identified a significant reduction in HbA1c levels, body weight, and TDID, and a substantial increase in 24-h UGE in patients who received dapagliflozin versus placebo.

Assessing the risk of ketoacidosis due to sodium-glucose cotransporter (SGLT)-2 inhibitors in patients with type 1 diabetes: A meta-analysis and meta-regression. PLoS Med 2020; 17:e1003461. [PMID: 33373368 PMCID: PMC7771708 DOI: 10.1371/journal.pmed.1003461] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Accepted: 11/23/2020] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Sodium-glucose cotransporter-2 (SGLT2) inhibitors (SGLT2i) showed benefits in type 1 diabetes mellitus (T1DM), but the risk of diabetic ketoacidosis (DKA) limits their use. Ability to predict DKA risk and therapeutic responses would enable appropriate patient selection for SGLT2i. We conducted a meta-analysis and meta-regression of randomized controlled trials (RCTs) evaluating SGLT2i in T1DM to assess moderators of the relative risk (RR) of DKA, of glycemic (HbA1c, fasting plasma glucose, continuous glucose monitoring parameters, insulin dose, and insulin sensitivity indices) and non-glycemic (body mass index (BMI), systolic BP, renal function, albuminuria, and diabetic eye disorders) efficacy, and of other safety outcomes (including hypoglycemia, infections, major adverse cardiovascular events, and death). METHODS AND FINDINGS We searched MEDLINE, Cochrane Library, EMBASE, ClinicalTrials.gov, Cochrane CENTRAL Register of Controlled Trials, and other electronic sources through August 30, 2020, for RCTs comparing SGLT2i with active comparators or placebo in adult patients with T1DM. Reviewers extracted data for relevant outcomes, performed random effects meta-analyses, subgroup analyses, and multivariable meta-regression. The strength of evidence was summarized with the GRADE approach. Among 9,914 records identified, 18 placebo-controlled RCTs (7,396 participants, 50% males, mean age 42 y (range 23 to 55 y), 5 different SGLT2i evaluated), were included. Main outcome measures were effect sizes and moderators of glycemic and non-glycemic efficacy and of safety outcomes. In a multivariable meta-regression model, baseline BMI (β = 0.439 [95% CI: 0.211, 0.666], p < 0.001) and estimated glucose disposal rate (eGDR) (β = -0.766 [-1.276, -0.256], p = 0.001) were associated with the RR of DKA (RR: 2.81; 95% CI:1.97, 4.01; p < 0.001, R2 = 61%). A model including also treatment-related parameters (insulin dose change-to-baseline insulin sensitivity ratio and volume depletion) explained 86% of variance across studies in the risk of DKA (R2 = 86%). The association of DKA with a BMI >27 kg/m2 and with an eGDR <8.3 mg/kg/min was confirmed also in subgroup analyses. Among efficacy outcomes, the novel findings were a reduction in albuminuria (WMD: -9.91, 95% CI: -16.26, -3.55 mg/g, p = 0.002), and in RR of diabetic eye disorders (RR: 0.27[0.11, 0.67], p = 0.005) associated with SGLT2i. A SGLT2i dose-response gradient was consistently observed for main efficacy outcomes, but not for adverse events (AEs). Overall, predictors of DKA and of other AEs differed substantially from those of glycemic and non-glycemic efficacy. A limitation of our analysis was the relatively short (≤52 weeks) duration of included RCTs. The potential relevance for clinical practice needs also to be confirmed by real-world prospective studies. CONCLUSIONS In T1DM, the risk of DKA and main therapeutic responses to SGLT2i are modified by baseline BMI and insulin resistance, by total insulin dose reduction-to-baseline insulin sensitivity ratio, and by volume depletion, which may enable the targeted use of these drugs in patients with the greatest benefit and the lowest risk of DKA.

Abstract
BACKGROUND The placebo response in patients with diabetes mellitus is very common. A systematic evaluation needs to be updated with the current evidence about the placebo response in diabetes mellitus and the associated factors in clinical trials of anti-diabetic medicine. METHODS Literature research was conducted in Medline, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov for studies published between the date of inception and June 2019. Randomized placebo-controlled trials conducted in type 1and type 2 diabetes mellitus (T1DM/T2DM) were included. Random-effects model and meta-regression analysis were accordingly used. This meta-analysis was registered in PROSPERO as CRD42014009373. RESULTS Significantly weight elevation (effect size (ES) = 0.33 kg, 95% CI, 0.03 to 0.61 kg) was observed in patients with placebo treatments in T1DM subgroup while significantly HbA1c reduction (ES = - 0.12%, 95% CI, - 0.16 to - 0.07%) and weight reduction (ES = - 0.40 kg, 95% CI, - 0.50 to - 0.29 kg) were observed in patients with placebo treatments in T2DM subgroup. Greater HbA1c reduction was observed in patients with injectable placebo treatments (ES = - 0.22%, 95% CI, - 0.32 to - 0.11%) versus oral types (ES = - 0.09%, 95% CI, - 0.14 to - 0.04%) in T2DM (P = 0.03). Older age (β = - 0.01, 95% CI, - 0.02 to - 0.01, P < 0.01) and longer diabetes duration (β = - 0.02, 95% CI, - 0.03 to - 0.21 × 10-2, P = 0.03) was significantly associated with more HbA1c reduction by placebo in T1DM. However, younger age (β = 0.02, 95% CI, 0.01 to 0.03, P = 0.01), lower male percentage (β = 0.01, 95% CI, 0.22 × 10-2, 0.01, P < 0.01), higher baseline BMI (β = - 0.02, 95% CI, - 0.04 to - 0.26 × 10-2, P = 0.02), and higher baseline HbA1c (β = - 0.09, 95% CI, - 0.16 to - 0.01, P = 0.02) were significantly associated with more HbA1c reduction by placebo in T2DM. Shorter diabetes duration (β = 0.06, 95% CI, 0.06 to 0.10, P < 0.01) was significantly associated with more weight reduction by placebo in T2DM. However, the associations between baseline BMI, baseline HbA1c, and placebo response were insignificant after the adjusted analyses. CONCLUSION The placebo response in diabetes mellitus was systematically outlined. Age, sex, disease severity (indirectly reflected by baseline BMI and baseline HbA1c), and disease duration were associated with placebo response in diabetes mellitus. The association between baseline BMI, baseline HbA1c, and placebo response may be the result of regression to the mean.

Abstract
AIM To conduct an overall safety assessment of sodium-glucose co-transporter-2 (SGLT-2) inhibitors used for the treatment of patients with type 1 diabetes (T1D), including ketoacidosis, genital infection, volume depletion, liver and kidney injury events, cardiovascular events, diarrhea and severe hypoglycaemia. MATERIALS AND METHODS We searched three databases (Pubmed, Embase and the Cochrane Library) for randomized controlled trials that treated T1D by using SGLT-2 inhibitors from 2000 to 5 March 2020. RESULTS Of the 1653 articles identified that fit our search criteria, 22 studies included qualitative-based results, eight of which were randomized clinical trials that included quantitative-based results. Compared with the control group, the SGLT-2 inhibitors treatment group was found to have had an increased incidence of ketoacidosis (P < .00001, OR 4.34, 95% CI [2.37, 7.96], I2 = 18%), events leading to discontinuation (P < .0001, OR 1.76, 95% CI [1.34, 2.31], I2 = 0%), genital infection (P < .00001, OR 3.64, 95% CI [2.82, 4.70], I2 = 0%), volume depletion (P = .006, OR 2.10, 95% CI [1.23, 3.59], I2 = 4%) and diarrhoea (P = .008, OR 1.64, 95% CI [1.14, 2.36], I2 = 0%). However, according to subgroup analysis, the risk of diarrhoea was dose-related. The incidence of urinary tract infection, cardiovascular events, renal events, liver injury and fracture was not significantly different for the treatment group compared with the control group. CONCLUSIONS Despite showing some promise as a treatment approach, the application of SGLT-2 inhibitors for patients with T1D should be considered with caution.

Abstract
In spite of developments with novel insulin preparations, novel modes of insulin delivery with insulin infusion pumps, and the facility of continuous glucose monitoring, only 20% of patients with type 1 diabetes are under adequate control. The need for innovation is clear, and, therefore, the use of adjunct therapies with other pharmacological agents currently in use for type 2 diabetes, has been tried. Currently, pramlintide is the only agent licensed for use in this condition in addition to insulin. Global trials have been conducted with liraglutide, a glucagon-like peptide 1 receptor agonist (GLP-1RA), dapagliflozin, a sodium glucose cotransporter 2 (SGLT2) inhibitor, and sotagliflozin, an inhibitor of both SGLT1 and SGLT2 transporters. While dapagliflozin and sotagliflozin have now been licensed for clinical use in this condition in Europe and Japan, they have hitherto not been licensed in the United States due to a small increase in the risk of diabetic ketoacidosis. However, these agents reduce glycosylated hemoglobin (HbA1c) by 0.4%, reduce glycemic oscillations, and do not increase the risk of hypoglycemia. Liraglutide, on the other hand, induced a smaller reduction in HbA1c and thus was not considered for a license. However, further trials are currently being conducted with a combination of semaglutide, the most potent GLP-1RA, and dapagliflozin to determine whether this approach would yield better outcomes.

Combination Therapy With Canagliflozin Plus Liraglutide Exerts Additive Effect on Weight Loss, but Not on HbA 1c, in Patients With Type 2 Diabetes. Diabetes Care 2020; 43:1234-1241. [PMID: 32220916 PMCID: PMC7411279 DOI: 10.2337/dc18-2460] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Accepted: 02/27/2020] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To examine the effect of combination therapy with canagliflozin plus liraglutide on HbA1c, endogenous glucose production (EGP), and body weight versus each therapy alone. RESEARCH DESIGN AND METHODS Forty-five patients with poorly controlled (HbA1c 7-11%) type 2 diabetes mellitus (T2DM) on metformin with or without sulfonylurea received a 9-h measurement of EGP with [3-3H]glucose infusion, after which they were randomized to receive 1) liraglutide 1.2 mg/day (LIRA), 2) canagliflozin 100 mg/day (CANA), or 3) liraglutide 1.2 mg plus canagliflozin 100 mg (CANA/LIRA) for 16 weeks. At 16 weeks, the EGP measurement was repeated. RESULTS The mean decrease from baseline to 16 weeks in HbA1c was -1.67 ± 0.29% (P = 0.0001), -0.89 ± 0.24% (P = 0.002), and -1.44 ± 0.39% (P = 0.004) in patients receiving CANA/LIRA, CANA, and LIRA, respectively. The decrease in body weight was -6.0 ± 0.8 kg (P < 0.0001), -3.5 ± 0.5 kg (P < 0.0001), and -1.9 ± 0.8 kg (P = 0.03), respectively. CANA monotherapy caused a 9% increase in basal rate of EGP (P < 0.05), which was accompanied by a 50% increase (P < 0.05) in plasma glucagon-to-insulin ratio. LIRA monotherapy reduced plasma glucagon concentration and inhibited EGP. In CANA/LIRA-treated patients, EGP increased by 15% (P < 0.05), even though the plasma insulin response was maintained at baseline and the CANA-induced rise in plasma glucagon concentration was blocked. CONCLUSIONS These results demonstrate that liraglutide failed to block the increase in EGP caused by canagliflozin despite blocking the rise in plasma glucagon and preventing the decrease in plasma insulin concentration caused by canagliflozin. The failure of liraglutide to prevent the increase in EGP caused by canagliflozin explains the lack of additive effect of these two agents on HbA1c.

Abstract
Aims: We evaluated the real-life efficacy and safety of empagliflozin in combination with optimized insulin therapy in patients with type 1 diabetes (T1D). Methods: This was a prospective study, including 27 patients with T1D treated with insulin therapy to whom empagliflozin was added according to an off-label protocol approved for use in clinical practice. The primary end point was the change in HbA1c 52 weeks after the addition of empagliflozin to insulin therapy. Blood pressure (BP), weight, and safety were also assessed. Results: At week 52, the addition of empagliflozin significantly reduced HbA1c from 8.0% ± 0.7% to 7.2% ± 0.8% (P < 0.001). The mean percentage of time in range for capillary glucose monitoring increased from 50% to 62% (P = 0.008) in parallel to a -0.08 IU/(kg·day) reduction in insulin requirements (P = 0.031). There was also a reduction in the body weight (-8 kg) and in systolic BP from 134 to 127 mmHg (P < 0.001). The most commonly reported adverse events were genitourinary infections (10 episodes in 52 weeks of follow-up). One patient developed an episode of mild diabetic ketoacidosis that motivated empagliflozin withdrawal. No severe hypoglycemic events were registered. Conclusions: Our results suggested that the use of empagliflozin following a strict off-label protocol may represent an effective and safe option in real life among patients with T1D, improving metabolic control, and ameliorating some cardiovascular risk factors.

Abstract
Cardiovascular outcome trials have provided evidence that sodium-glucose cotransporter 2 inhibitor (SGLT2i) treatment is associated with remarkably favorable cardiovascular outcomes. Here, we offer a novel hypothesis that may encompass many of these hypothetical mechanisms, i.e., the ability of SGLT2i to modify the trajectory of cell response to a toxic environment through modifications of cellular life history programs, either the defense program or the dormancy program. The choice between these programs is mainly determined by the environment. Hyperglycemia can be considered a toxic determinant able to interfere with the basic programs of cell evolution. While the defense program is characterized by activation of the immune response and anabolic metabolism, the dormancy program is an energy-preserving state with high resistance to environmental stressors, and it has strong analogy with animal hibernation where fuel is stored, metabolic rate is suppressed, and insulin secretion is reduced. The metabolic changes that follow treatment with SGLT2i are reminiscent of the metabolic picture characteristic of the dormancy program. Therefore, we hypothesize that the beneficial cardioprotective effects of SGLT2i may be related to their ability to switch cell life programming from a defense to a dormancy state, thus lending additional benefit.

Abstract
PURPOSE OF REVIEW Dementia is rapidly growing as sources of morbidity and mortality as the US population ages, but its pathophysiology remains poorly understood. As a result, no disease-modifying treatments currently exist. We review the evidence that nonesterified fatty acids may play a key role in this condition. RECENT FINDINGS Nonesterified fatty acids appear to influence several pathways leading to dementia. In addition to their vascular effects, these moieties cross the blood-brain barrier, where they are toxic to several cell types. They may also influence insulin metabolism in the brain directly and indirectly, and some drugs that lower circulating levels appear to slow cognitive decline and brain atrophy in diabetes. SUMMARY Nonesterified fatty acids may contribute to dementia, much as they do to diabetes and cardiovascular disease. Several therapeutic agents lower circulating levels of nonesterified fatty acids and should be tested for their potential preventive effects on cognitive decline in healthy populations before irreversible neuronal attrition occurs.

Abstract
BACKGROUND The safety and efficacy of sodium glucose co-transporter 2 (SGLT2) inhibitors in a dose-dependent manner for type 1 diabetes mellitus (T1DM) are unclear. METHODS Randomized clinical trials (RCT) were searched from PubMed, EMBASE, the Cochrane Library, Web of Science and ClinicalTrials until August 2018. RESULTS Thirteen RCT with 5397 participants were included. SGLT2 inhibitors were proved to be effective in glycemic control and weight loss in T1DM. In the subgroups of different doses, SGLT2 inhibitors exhibited reductions in glycated haemoglobin, bodyweight, fasting plasma glucose, mean daily glucose, basal insulin dose, bolus insulin dose, estimated glomerular filtration rate and systolic blood pressure, and elevations in the mean amplitude of glucose excursions, and percentage of time in target glucose range in a dose-dependent manner. Reductions in total insulin dose and urinary glucose excretion were dose-independent. SGLT2 inhibitors did not induce hypoglycemia, severe hypoglycemia, cardiovascular events, bone fracture and all-cause mortality, but increased the risk of adverse events (AE), adverse events related to the drug treatment, infections, diabetic ketoacidosis (DKA) and renal disease correlated with dosage. CONCLUSIONS SGLT2 inhibitors in high and moderate doses can achieve a better outcome on efficacy, but may induce a higher risk of adverse events, especially DKA.

Diabetes Obes Metab 2019; 21 Suppl 2:62-77.

Abstract
Many patients with type 1 diabetes (T1D) struggle to achieve glycaemic control and experience significant fluctuations in glucose concentrations, despite insulin treatment. Sodium-glucose co-transporter (SGLT)-2 inhibitors and dual SGLT-1/2 inhibitors increase glucose elimination via the kidneys and reduce hyperglycaemia via insulin-independent mechanisms. This review examines available efficacy and safety data for these agents under investigation as adjunctive therapy for T1D. Across randomized trials of up to 52 weeks, SGLT-2 inhibitors or SGLT-1/2 inhibitors as an adjunct to insulin demonstrated significant reductions in glycated haemoglobin, glucose exposure, and measures of glycaemic variability, as well as increased time in the target glycaemic range, compared with placebo. Non-glycaemic benefits included reductions in body weight and insulin doses, as well as improvements in some cardiovascular risk factors and treatment satisfaction. SGLT-2 inhibitors and SGLT-1/2 inhibitors were associated with similar rates of hypoglycaemia but a higher incidence of genitourinary infections, compared with placebo. Diabetic ketoacidosis occurred more often with SGLT-2 inhibitors and SGLT-1/2 inhibitors vs placebo, although the incidence was generally low. Risk mitigation strategies in light of clinical trial data are also discussed. Positive data from randomized controlled trials of the SGLT-2 inhibitor dapagliflozin have led to the approval of dapagliflozin as an adjunct to insulin in adults with T1D having body mass index ≥27 kg/m2 in whom insulin does not provide adequate glycaemic control in Europe and to approval as an adjunct to insulin for adults with T1D in Japan.

Abstract
For type 1 diabetes patients with inadequate glycemic control, one treatment option is to increase the insulin dose (scenario 1), which should not give rise to a “metabolic imbalance.” A second option is additional treatment with a sodium–glucose cotransporter 2 inhibitor, which might lead to a “metabolic imbalance” (scenario 2). A reduction in insulin dose in addition to administration of a sodium–glucose cotransporter 2 inhibitor might further increase the “metabolic imbalance” (scenario 3).![]()

Abstract
OBJECTIVE People with type 1 diabetes often have suboptimal glycemic control. The gold standard of treatment is basal-bolus insulin or subcutaneous insulin infusion via insulin pump. Although insulin therapy improves glycemic control, weight gain and hypoglycemia often limit achievement of hemoglobin A1C (A1C) goals. The number of people with type 1 diabetes who are overweight or obese is increasing, and there are many similarities between what was historically called type 1 and type 2 diabetes. Therefore, there is rationale for using antihyperglycemic agents that target other pathophysiological abnormalities to facilitate weight loss and improve glycemic control. DATA SOURCES We performed a MEDLINE search from 1975 through October 2018 to identify articles that studied noninsulin agents in adults with type 1 diabetes and body mass index (BMI) ≥25 kg/m2. STUDY SELECTION AND DATA EXTRACTION Identified articles were included if the study duration was ≥4 weeks, included ≥20 patients, and set mean baseline BMI ⩾25kg/m2. DATA SYNTHESIS This review summarizes 32 clinical trials. Amylin mimetics, sodium-glucose-like transporter-2 inhibitors, and glucagon-like-peptide-1 receptor agonists demonstrate the greatest improvements in body weight and A1C. The most common adverse effects are hypoglycemia and ketosis. Relevance to Patient Care and Clinical Practice: Patients with type 1 diabetes may have interest in starting noninsulin agents. Clinicians need to be knowledgeable in the efficacy and adverse effect profile of these agents, specifically in people with type 1 diabetes. CONCLUSIONS Adding noninsulin antihyperglycemic agents may benefit select overweight or obese adults with type 1 diabetes. These agents are off-label, and if used, close monitoring is essential.

Abstract
We investigated the short-term effects of dapagliflozin as adjunct to insulin on insulin sensitivity, postprandial glucose excursions and ketone body production in type 1 diabetes mellitus (T1DM). A total of seven male patients completed the randomized, double-blind, placebo-controlled cross-over trial, receiving 10 mg of dapagliflozin daily for 3 days, followed by placebo, or the reverse. At Day 3, hyperinsulinaemic, euglycaemic clamps and oral glucose tolerance test clamps with repeated blood sampling were performed. Required glucose infusion and blood glucose excursions did not differ significantly between dapagliflozin treatment and placebo (P = 0.491; P = 0.342). Prior to oral glucose, total ketone bodies showed a higher trend following dapagliflozin treatment (P = 0.051). Following oral glucose, total ketone bodies decreased while concentrations of total GLP-1 were higher following dapagliflozin (P = 0.009). Non-esterified free fatty acids did not differ between dapagliflozin treatment and placebo and ketonuria was absent under both conditions. In T1DM, short-term addition of dapagliflozin to insulin influenced neither postprandial glucose excursions nor insulin sensitivity. Following oral glucose, total ketone bodies decreased in parallel with an increase in GLP-1 concentrations, which were higher under dapagliflozin treatment as compared with placebo.

Abstract
OBJECTIVE This 24-week, double-blinded, phase 3 clinical trial (DEPICT-2; ClinicalTrials.gov, NCT02460978) evaluated efficacy and safety of dapagliflozin as adjunct therapy to adjustable insulin in patients with inadequately controlled type 1 diabetes (HbA1c 7.5-10.5%). RESEARCH DESIGN AND METHODS Patients were randomized 1:1:1 to dapagliflozin 5 mg (n = 271), dapagliflozin 10 mg (n = 270), or placebo (n = 272) plus insulin. Insulin dose was adjusted by investigators according to self-monitored glucose readings, local guidance, and individual circumstances. RESULTS Baseline characteristics were balanced between treatment groups. At week 24, dapagliflozin significantly decreased HbA1c (primary outcome; difference vs. placebo: dapagliflozin 5 mg -0.37% [95% CI -0.49, -0.26], dapagliflozin 10 mg -0.42% [-0.53, -0.30]), total daily insulin dose (-10.78% [-13.73, -7.72] and -11.08% [-14.04, -8.02], respectively), and body weight (-3.21% [-3.96, -2.45] and -3.74% [-4.49, -2.99], respectively) (P < 0.0001 for all). Mean interstitial glucose, amplitude of glucose excursion, and percent of readings within target glycemic range (>70 to ≤180 mg/dL) versus placebo were significantly improved. More patients receiving dapagliflozin achieved a reduction in HbA1c ≥0.5% without severe hypoglycemia compared with placebo. Adverse events were reported for 72.7%, 67.0%, and 63.2% of patients receiving dapagliflozin 5 mg, dapagliflozin 10 mg, and placebo, respectively. Hypoglycemia, including severe hypoglycemia, was balanced between groups. There were more adjudicated definite diabetic ketoacidosis (DKA) events with dapagliflozin: 2.6%, 2.2%, and 0% for dapagliflozin 5 mg, dapagliflozin 10 mg, and placebo, respectively. CONCLUSIONS Dapagliflozin as adjunct therapy to adjustable insulin in patients with type 1 diabetes was well tolerated and improved glycemic control with no increase in hypoglycemia versus placebo but with more DKA events.

Abstract
INTRODUCTION Despite intensified insulin treatment, many persons with type 1 diabetes (T1D) do not achieve glycemic and metabolic targets. Consequently, non-insulin chemical therapies that improve glycemic control and metabolic parameters without increasing the risk of adverse events (including hypoglycemia) are of interest as adjunct therapies to insulin. AREAS COVERED In this review, the authors discuss the efficacy and safety of non-insulin therapies, including pramlintide, glucagon-like peptide-1 (GLP-1) receptor agonists, dipeptidyl peptidase-4 inhibitors (DPP-4), sodium-glucose cotransporter (SGLT1 and SGLT2) inhibitors, metformin, sulfonylureas, and thiazolidinediones as add-on therapies to insulin in T1D. EXPERT OPINION The current evidence shows that the efficacy of non-insulin therapies as add-on therapies to insulin is minimal or modest with an average HbA1c reduction of 0.2-0.5% (2-6 mmol/mol). Indeed, the current focus is on the development of SGLT inhibitors as adjuncts to insulin in type 1 diabetes. Studies of subgroups with obesity, residual beta-cell function (including newly diagnosed patients) and patients prone to hypoglycemia could be areas of future research.

Abstract
PURPOSE OF REVIEW To identify and evaluate the recent trials of sodium-glucose cotransporter 1 and 2 (SGLT1 and SGLT2, respectively) inhibitor use in patients with type 1 diabetes (T1D). SGLT-2 inhibitors have been approved by the Food and Drug Administration (FDA) and are effectively used in the treatment of type 2 diabetes (T2D). However, many studies (phase I-III) have validated their effects beyond improving glycemic control and have shown potential adjunctive use in adult patients with T1D treated with insulin therapy alone. RECENT FINDINGS A review of the literature showed that there is a potential adjunctive role for the SGLT inhibitors with insulin in T1D for improving glycemic control. The inTandem3 (A phase III study to evaluate the safety of sotagliflozin in patients with type 1 diabetes who have inadequate glycemic control with insulin therapy alone) and the DEPICT-1 (Dapagliflozin evaluation in patients with inadequately controlled type 1 diabetes) trials demonstrated significant benefits in adult patients with T1D. The SGLT inhibitors may become the first oral medication to be approved for adjunctive use in T1D. SUMMARY The risk of diabetic ketoacidosis still remains a concern, but considering additional benefits beyond glucose control, with proper counseling and education, these medications may allow a larger number of patients to achieve target glucose control without weight gain or increased risk of hypoglycemia.

Abstract
New treatments for type 1 diabetes are an unmet need. We investigated the efficacy and safety of adding sodium-glucose co-transporter-2 (SGLT2) inhibitors to insulin for type 1 diabetes by conducting a meta-analysis of prospective randomized, placebo-controlled trials. A search of electronic databases up to October 2017 identified 1361 studies, of which 14 were investigated (N = 4591). Meta-analysis showed that SGLT2 inhibitor therapy significantly reduced glycated haemoglobin (HbA1c) concentration by 0.4% (95% confidence interval [CI] 0.35, 0.46; P < .001, I2 = 0%), fasting plasma glucose by 1.14 mmol/L (95% CI 0.8,1.47), body weight by 2.68 kg (95% CI 2.0, 3.36), and systolic blood pressure by 3.37 mmHg (95% CI 1.46, 5.28). In addition, bolus insulin decreased by 3.6 units/day (95% CI 2.0, 5.3), and basal insulin decreased by 4.2 units/day (95% CI 2.2, 6.3). Continuous glucose monitoring showed a decrease in glucose excursions compared with placebo, with reduced variation of mean blood glucose, glucose standard deviation, and mean amplitude of glucose excursion. There was no significant increase in the rate of hypoglycaemia or severe hypoglycaemia; however, SGLT2 inhibitor therapy increased diabetic ketoacidosis (odds ratio [OR] 3.38) and genital tract infection (OR 3.44). Add-on SGLT2 inhibitor therapy might be advantageous for type 1 diabetes, but its use should be considered carefully.

Abstract
The sodium-glucose cotransporter type 1 (SGLT1) is the primary transporter for absorption of glucose and galactose in the gastrointestinal tract. Inhibition blunts and delays postprandial glucose (PPG) excursion. Sodium-glucose cotransporter type 2 (SGLT2) is expressed in the kidney, where it reabsorbs 90% of filtered glucose. Thus, a dual SGLT1 and SGLT2 inhibition (compared with selective SGLT2 inhibition) could result in lower PPG and robust A1c reduction even in patients with reduced kidney function. Sotagliflozin is an oral potent dual inhibitor of the insulin-independent SGLT1 and SGLT2. Preliminary data released from phase 2 and 3 clinical studies in adults with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) showed improved glycemic control, and met efficacy endpoints beyond A1c with a safety profile consistent with the SGLT class: significant reduction in body weight, systolic blood pressure, and efficacy maintained in lower estimated glomerular filtration rate levels with no increased hypoglycemia. Increased risk of diabetic ketoacidosis (DKA) with uncharacteristically mild-to-moderate glucose elevations (euglycemic DKA) is associated with the use of all the approved SGLT2 inhibitors. Factors that trigger DKA include insulin reductions, low caloric and fluid intake, intercurrent illness, and alcohol use. However, DKA is detectable and manageable with proper patient education. With sotagliflozin, DKA rates were not higher than the expected background rate in T1DM, but numerically higher than placebo. Sotagliflozin is the first oral SGLT1 and SGLT2 inhibitor developed for the treatment of adult patients with T1DM, in adjunct with insulin, and has the potential to address unmet needs for patients with T1DM and possibly T2DM, with a favorable benefit/risk profile.

Abstract
INTRODUCTION There is a clear unmet clinical need in people with Type 1 diabetes (T1DM) considering present day insulin therapy. New insulin analogues and novel technologies allowing more tailored insulin administration have improved the quality of life of people with T1DM, but issues like hypoglycemia, weight gain and variability in glucose profiles remain problematic. Areas covered: In this review, the clinical efficacy, safety and tolerability of dapagliflozin, a sodium-glucose cotransporter type 2 inhibitor, in type 1 diabetes (T1DM) is described based on a review of phase 2 and 3 studies to date. Expert opinion: Dapagliflozin has shown promising results as an adjunct therapy in T1DM, resulting in better glucose control, weight loss and lower blood pressure. No increase in hypoglycemia risk, in particular severe hypoglycemia, was observed, but, in comparison with reports in Type 2 diabetes (T2DM), genital infections were more prevalent. Dapagliflozin use was accompanied with decreases in insulin doses, but, to date, only a low risk of diabetic ketoacidosis (DKA) was reported. However, caution is needed when interpreting this data, arising from well controlled clinical trials, with intensive education programs around ketone measurements and DKA prevention. Further studies will need to establish how high the DKA risk is and how to mitigate this in a real-world setting.

Abstract
AIMS Sodium-glucose cotransporter 2 (SGLT2) inhibitors are currently FDA approved for the management of type 2 diabetes. Our objective was to review the available evidence of the effects of SGLT2 inhibitors on HbA1c, body weight, and total daily insulin dose, as well as their safety profile in patients with type 1 diabetes. METHODS Four randomized controlled trials (RCTs) were identified by conducting a systematic search of PubMed, Embase, Web of Science, Scopus and Cochrane library databases through August 2017. Data on study design, sample size, mean ± standard deviation of HbA1c, body weight, and total daily insulin dose, as well as reported adverse events were extracted. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were calculated using a random-effects model. RESULTS Relative to placebo, therapy with SGLT2 inhibitors led to significant reductions in HbA1c (WMD 0.39; 95% CI 0.27, 0.51), body weight (WMD 2.76; 95% CI 1.11, 4.40), and total daily insulin dose (WMD 5.03; 95% CI 1.83, 8.23). In addition, there was no significant difference in the rate of adverse events. CONCLUSIONS The current study lends supports for the development of SGLT2 inhibitors in combination with insulin as a treatment option for patients with type 1 diabetes.

Abstract
While the use of incretins, including GLP-1 receptor agonists and PDD-IV inhibitors, is well established in the treatment of type 2 diabetes, many other aspects of these agents are yet to be discovered and utilized for their potential clinical benefit. These include the potential role of GLP-1 receptor agonists in the induction of weight loss, blood pressure reduction, anti-inflammatory and nephro- and cardio-protective actions. Their potential benefit in type 1 diabetes is also being investigated. This review will attempt to comprehensively describe novel discoveries in the field of incretin pathophysiology and pharmacology beyond their classical role in the treatment of type 2 diabetes.

Abstract
Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are increasingly used for the treatment of type 2 diabetes (T2D) and can improve glucose control also in type 1 diabetes (T1D). In May 2015, regulatory agencies issued a warning that SGLT2is may cause diabetic ketoacidosis (DKA). We report details on 2 new cases of SGLT2i-associated DKA and review the literature for similar cases within randomized controlled trials (RCTs), cohort studies and single reports. We searched the medical literature for reports of SGLT2i-associated DKA cases. A quantitative analysis of frequency and clinical characteristics is reported. The 2 narrative cases illustrate that SGLT2i-associated DKA can occur in patients with T1D incorrectly diagnosed as T2D, perhaps without the presence of obvious DKA precipitating factors. The incidence of SGLT2i-associated DKA was less than 1/1000 in randomized controlled trials and 1.6/1000 person-years in cohort studies. We retrieved detailed data on 105 SGLT2i-associated DKA case reports, wherein 35% showed glucose levels of less than 200 mg/dL and 22% were not associated with typical triggers. In case reports and in pharmacovigilance databases, duration of SGLT2i treatment before DKA onset was extremely variable. Fatal SGLT2i-associated DKA episodes were found only in pharmacovigilance databases and represented 1.6% of all reported cases. DKA is a rare adverse event during SGLT2i therapy. Predisposing and precipitating factors are still incompletely understood, although a minority of cases lacked typical DKA triggers. More narrative case series and cohort studies are needed to better understand the true risk and the spectrum of this adverse event.

Abstract
Type 1 diabetes mellitus (T1DM) is characterized by relative or absolute insulin deficiency. Despite treatment with insulin therapy, glycemic goals are not always met, and insulin therapy is sometimes limited by adverse effects, including hypoglycemia and weight gain. Several adjunctive therapies have been evaluated in combination with insulin in patients with T1DM to improve glycemic control while minimizing adverse effects. Pramlintide, an amylin analog, can improve glycemic control, primarily through lowering postprandial blood glucose levels. Patients may experience weight loss and an increased risk of hypoglycemia and require additional mealtime injections. Metformin provides an inexpensive, oral treatment option and may reduce blood glucose, especially in overweight or obese patients with minimal risk of hypoglycemia. Metformin may be more effective in patients with impaired insulin sensitivity. Glucagon-like peptide-1 receptor agonists reduce primarily postprandial blood glucose and insulin dose and promote weight loss. They are expensive, cause transient nausea, may increase risk of hypoglycemia and require additional injections. Sodium-glucose transport-2 inhibitors improve glycemic control, promote weight loss and have low risk of hypoglycemia with appropriate insulin adjustment; however, these agents may increase the risk of diabetic ketoacidosis in patients with T1DM. Patient-specific characteristics should be considered when selecting adjunctive therapy for patients with T1DM. Close monitoring, insulin dose adjustments and patient education are all important to ensure safe and effective use of these agents.

Lancet Diabetes Endocrinol 2017; 5:864-876.

Abstract
BACKGROUND Dapagliflozin is a sodium-glucose cotransporter-2 inhibitor approved for the treatment of type 2 diabetes. We aimed to assess the efficacy and safety of dapagliflozin as an add-on to adjustable insulin in patients with inadequately controlled type 1 diabetes. METHODS DEPICT-1 was a double-blind, randomised, parallel-controlled, three-arm, phase 3, multicentre study done at 143 sites in 17 countries. Eligible patients were aged 18-75 years and had inadequately controlled type 1 diabetes (HbA1c between ≥7·7% and ≤11·0% [≥61·0 mmol/mol and ≤97·0 mmol/mol]) and had been prescribed insulin for at least 12 months before enrolment. After an 8 week lead-in period to optimise diabetes management, patients were randomly assigned (1:1:1) using an interactive voice response system to dapagliflozin 5 mg or 10 mg once daily, given orally, or matched placebo. Randomisation was stratified by current use of continuous glucose monitoring, method of insulin administration, and baseline HbA1c. The primary efficacy outcome was the change from baseline in HbA1c after 24 weeks of treatment in the full analysis set, which consisted of all randomly assigned patients who received at least one dose of study drug. An additional 55 patients who were incorrectly and non-randomly allocated to only dapagliflozin treatment groups were included in the safety analysis set. This study was registered with ClinicalTrials.gov, number NCT02268214; data collection for the present analysis was completed on Jan 4, 2017, and a 28 week extension phase is ongoing. FINDINGS Between Nov 11, 2014, and April 16, 2016, 833 patients were assigned to treatment groups and included in safety analyses (dapagliflozin 5 mg [n=277] vs dapagliflozin 10 mg [n=296] vs placebo [n=260]; 778 of these patients were randomly assigned and included in the full analysis set for efficacy analyses (259 vs 259 vs 260; difference due to randomisation error affecting 55 patients). Mean baseline HbA1c was 8·53% (70 mmol/mol; SD 0·67% [7·3 mmol/mol]). At week 24, both doses of dapagliflozin significantly reduced HbA1c compared with placebo (mean difference from baseline to week 24 for dapagliflozin 5 mg vs placebo was -0·42% [95% CI -0·56 to -0·28; p<0·0001] and for dapagliflozin 10 mg vs placebo was -0·45% [-0·58 to -0·31; p<0·0001]). Among patients in the dapagliflozin 5 mg (n=277), dapagliflozin 10 mg (n=296), and placebo (n=260) groups, the most common adverse events were nasopharyngitis (38 [14%] vs 36 [12%] vs 39 [15%]), urinary tract infection (19 [7%] vs 11 [4%] vs 13 [5%]), upper respiratory tract infection (15 [5%] vs 15 [5%] vs 11 [4%]), and headache (12 [4%] vs 17 [6%] vs 11 [4%]). Hypoglycaemia occurred in 220 (79%), 235 (79%), and 207 (80%) patients in the dapagliflozin 5 mg, dapagliflozin 10 mg, and placebo groups, respectively; severe hypoglycaemia occurred in 21 (8%), 19 (6%), and 19 (7%) patients, respectively. Adjudicated definite diabetic ketoacidosis occurred in four (1%) patients in the dapagliflozin 5 mg group, five (2%) in the dapagliflozin 10 mg group, and three (1%) in the placebo group. INTERPRETATION Our results suggest that dapagliflozin is a promising adjunct treatment to insulin to improve glycaemic control in patients with inadequately controlled type 1 diabetes.

Liraglutide acutely suppresses glucagon, lipolysis and ketogenesis in type 1 diabetes. Diabetes Obes Metab 2017; 19:1306-1311.

Abstract
In view of the occurrence of diabetic ketoacidosis associated with the use of sodium-glucose transport protein-2 inhibitors in patients with type 1 diabetes (T1DM) and the relative absence of this complication in patients treated with liraglutide in spite of reductions in insulin doses, we investigated the effect of liraglutide on ketogenesis. Twenty-six patients with inadequately controlled T1DM were randomly divided into 2 groups of 13 patients each. After an overnight fast, patients were injected, subcutaneously, with either liraglutide 1.8 mg or with placebo. They were maintained on their basal insulin infusion and were followed up in our clinical research unit for 5 hours. The patients injected with placebo maintained their glucose and glucagon concentrations without an increase, but there was a significant increase in free fatty acids (FFA), acetoacetate and β-hydoxybutyrate concentrations. In contrast, liraglutide significantly reduced the increase in FFA, and totally prevented the increase in acetoacetate and β-hydroxybutyrate concentrations while suppressing glucagon and ghrelin concentrations. Thus, a single dose of liraglutide is acutely inhibitory to ketogenesis.
