Abstract
AIMS/INTRODUCTION In the present meta-analysis, we aimed to determine the effects of sodium-glucose cotransporter 2 inhibitor (SGLT-2i) in addition to insulin therapy on cardiovascular risk factors in type 2 diabetes patients. MATERIALS AND METHODS Randomized controlled trials were identified by searching the PubMed, Embase and Cochrane Library databases published before September 2017. The intervention group received SGLT-2i as add-on treatment to insulin therapy, and the control group received placebos in addition to insulin. We assessed pooled data, including weighted mean differences and 95% confidence intervals (CIs) using a random-effects model. RESULTS A total of 10 randomized controlled trials (n = 5,159) were eligible. The weighted mean differences for systolic blood pressure and diastolic blood pressure were -3.17 mmHg (95% CI -4.53, -1.80, I2 = 0%) and -1.60 mmHg (95% CI -2.52, -0.69, I2 = 0%) in the intervention groups. Glycosylated hemoglobin, fasting plasma glucose, postprandial glucose and daily insulin were also lower in the intervention groups, with relative weighted mean differences of -0.49% (95% CI -0.71, -0.28%, I2 = 92%), -1.10 mmol/L (95% CI -1.69, -0.51 mmol/L, I2 = 84%), -3.63 mmol/L (95% CI -4.36, -2.89, I2 = 0%) and -5.42 IU/day (95% CI -8.12, -2.72, I2 = 93%). The transformations of uric acid and bodyweight were -26.16 μmol/L (95% CI -42.14, -10.17, I2 = 80%) and -2.13 kg (95% CI -2.66, -1.60, I2 = 83%). The relative risk of hypoglycemia was 1.09 (95% CI 1.02, 1.17, P < 0.01). The relative risks of urinary tract and genital infection were 1.29 (95% CI 1.03, 1.62, P = 0.03) and 5.25 (95% CI 3.55, 7.74, P < 0.01). CONCLUSIONS The results showed that in the intervention group, greater reductions were achieved for blood pressure, glucose control, uric acid and bodyweight. This treatment regimen might therefore provide beneficial effects on the occurrence and development of cardiovascular events.

Journal of diabetes investigation. 2019;(1):108-117
Abstract
AIMS/INTRODUCTION It is unclear how changes in body composition induced by sodium-glucose cotransporter 2 (SGLT2) inhibitor treatment correlate with metabolic profile changes. We aimed to clarify how metabolic profile changes correlate with body component changes, and if SGLT2 inhibitor treatment causes sarcopenia and bone mineral content (BMC) loss. MATERIALS AND METHODS Moderately obese Japanese type 2 diabetes patients, treated with luseogliflozin for a year, were observed prospectively and evaluated for body composition changes. We analyzed the changes in the individual body components during treatment, and their correlation with other clinical variables. RESULTS The efficacy analysis set comprised 37 of 43 enrolled patients. The total fat mass significantly decreased early in the treatment at and after week 4, with a mean decrease of -1.97 kg (95% confidence interval -2.66 to -1.28) at week 24. The visceral fat area at week 24 showed an average downward trend, although this was not significant. The changes in visceral fat area in individual patients showed a significant negative correlation with the extent of the baseline visceral fat area (r = -0.399, P = 0.023). The skeletal muscle mass index showed a significant but small change at and after week 36. The BMC profile showed a transient significant decrease only at week 12. No significant change in BMC was noted at other time-points. CONCLUSIONS Luseogliflozin treatment brought about favorable changes in body composition and metabolism of moderately obese Japanese type 2 diabetes patients, accompanied by body fat reduction, and minimal muscle and BMC reduction.

[Application of new glucose lowering drugs: DPP-4 inhibitors, GLP-1 receptor agonists and SGLT-2 inhibitors].
Verburg, AFE, van den Donk, M, Wiersma, T
Nederlands tijdschrift voor geneeskunde. 2019
Abstract
A comprehensive review of the literature on DPP-4 inhibitors, GLP-1 receptor agonists and SGLT-2 inhibitors has resulted in small changes to the medication roadmap of the type 2 diabetes mellitus standard of the Dutch College of General Practitioners. SGLT-2 inhibitors and GLP-1 receptor agonists may have benefits related to cardiovascular outcomes in patients with high cardiovascular risk, especially in those who have experienced a cardiovascular event. However, ascribing effectiveness related to cardiovascular outcomes on the basis of a single cardiovascular safety trial is premature. Metformin, sulfonylurea derivatives and insulin are still the cornerstone of type 2 diabetes mellitus treatment in primary care.

Abstract
OBJECTIVE In people with type 2 diabetes, sodium-glucose cotransporter 2 inhibitors (SGLT2i) reduce cardiovascular risk and progression of diabetic kidney disease. Our aim was to determine whether sotagliflozin (SOTA), a dual SGLT1i and SGLT2i, had favorable effects on clinical biomarkers suggestive of kidney protection in adults with type 1 diabetes. RESEARCH DESIGN AND METHODS In this 52-week pooled analysis, 1,575 adults enrolled in the inTandem1 and inTandem2 trials were randomized to SOTA 200 mg, 400 mg, or placebo in addition to optimized insulin therapy. Changes in cardiorenal biomarkers were assessed. RESULTS At 52 weeks, in response to SOTA 200 and 400 mg, the placebo-corrected least squares mean change from baseline in estimated glomerular filtration rate was -2.0 mL/min/1.73 m2 (P = 0.010) and -0.5 mL/min/1.73 m2 (P = 0.52), respectively. Systolic blood pressure difference was -2.9 and -3.6 mmHg (P < 0.0001 for both); diastolic blood pressure changed by -1.4 (P = 0.0033) and -1.6 mmHg (P = 0.0008). In participants with baseline urinary albumin-to-creatinine ratio (UACR) ≥30 mg/g, UACR decreased by 23.7% (P = 0.054) and 18.3% (P = 0.18) for SOTA 200 and SOTA 400 mg, respectively, versus placebo. Increases in serum albumin and hematocrit and reductions in uric acid were observed throughout 52 weeks with both SOTA doses. CONCLUSIONS SOTA was associated with short- and long-term renal hemodynamic changes, which were similar to those seen with SGLT2i in type 2 diabetes. Further investigation around cardiorenal effects of SOTA in people with type 1 diabetes is justified.

Abstract
BACKGROUND The aim of the study is to update and determine the effects of sodium glucose cotransporter 2 (SGLT2) inhibitor therapy on fracture and bone mineral density (BMD) in patients with type 2 diabetes mellitus (T2DM). METHODS We identified 27 eligible randomized controlled trials (RCTs) that compared the efficacy and safety of SGLT2 inhibitors to a placebo in 20 895 T2DM participants, with an average duration of 64.22 weeks. The relative risk (RR) of bone fracture and weighted mean difference (WMD) of changes in the BMD from baseline were determined to evaluate the risk of fracture. The degree of heterogeneity was evaluated by the I2 statistic, and publication bias was estimated using a funnel plot and Egger test. RESULTS The pooled RR was 1.02 (95% CI [0.81, 1.28]) with low heterogeneity, indicating that SGLT2 inhibitor treatment was not correlated with a higher risk of fracture. Additionally, no increased risk was found for patients with different ages, sexes, and levels of HbA1c and some biochemical indicators. Three trials with 1303 patients reported a change in the BMD from baseline. SGLT2 inhibitor treatment did not decrease the BMD at four skeletal sites (lumbar spine, femoral neck, total hip, and distal forearm), and the overall WMD was 0.08 (95% CI [-0.09, 0.26]). No significant publication bias was detected. CONCLUSIONS No increased risk for bone fracture was detected in patients with T2DM treated with SGLT2 inhibitors in this meta-analysis. SGLT2 inhibitor therapy did not appear to affect bone health, but more long-term detailed data are needed to validate this conclusion.

Clinical therapeutics. 2019;(2):322-334.e11
Abstract
PURPOSE The aim of this study was to systematically evaluate the effect of sodium-glucose cotransporter 2 (SGLT2) inhibitor monotherapy on the weight of patients with type 2 diabetes mellitus (T2DM) and to compare different SGLT2 inhibitors with other oral glucose-lowering medications. METHODS PubMed, EMBASE, Cochrane Library, and the ClinicalTrials.gov Web site were searched for relevant randomized controlled trials. Patients with T2DM in the included studies were administered SGLT2 inhibitor monotherapy for at least 12 weeks. The primary outcome was the change in weight from baseline; the secondary outcome was the proportion of patients achieving a weight reduction ≥5%. A pairwise meta-analysis using the DerSimonian-Laird random effects model and a network meta-analysis with Bayesian Markov chain Monte Carlo random effects models were performed. FINDINGS A total of 29 randomized controlled trials (11,999 patients) with a low risk of bias were identified. The results showed that the mean weight loss ranged from -2.26 kg (95% credible interval [CrI], -2.71 to -1.76) with canagliflozin 300 mg to -0.79 kg (95% CrI, -1.54 to -0.05) with ipragliflozin 25 mg compared with metformin. Compared with linagliptin and sitagliptin, the mean weight loss ranged from -3.17 kg (95% CrI, -3.67 to -2.57) with canagliflozin 300 mg to -0.93 kg (95% CrI, -1.92 to 0.05) with ipragliflozin 25 mg. Canagliflozin 300 mg reduced weight to a greater extent than the other SGLT2 inhibitors, with a probability of 99.44%. SGLT2 inhibitors also improved the proportions of patients achieving ≥5% weight loss. The effect of SGLT2 inhibitors on weight reduction was associated with dosage. IMPLICATIONS Available evidence from randomized controlled trials suggests that SGLT2 inhibitor monotherapy exerts more beneficial effects on weight reduction than both metformin and dipeptidyl peptidase 4 inhibitors. The weight reduction effect of 300 mg canagliflozin is greater than that of most other SGLT2 inhibitors. More types of SGLT2 inhibitors in a head-to-head trial, as well as a comparison between SGLT2 inhibitors and glucagon-like peptide 1 receptor agonists, will be involved in our further research.

Journal of diabetes investigation. 2019;(4):1004-1011
Abstract
AIMS/INTRODUCTION Non-alcoholic fatty liver disease is frequently associated with type 2 diabetes, and constitutes an important risk factor for the development of hepatic fibrosis and hepatocellular carcinoma. Because there remains no effective drug therapy for non-alcoholic fatty liver disease associated with type 2 diabetes, we evaluated the efficacy of sodium-glucose cotransporter 2 inhibitor. METHODS AND MATERIALS In the present pilot, prospective, non-randomized, open-label, single-arm study, we evaluated the effect of 100 mg canagliflozin administered once daily for 12 months on serological markers, body composition measured by bioelectrical impedance analysis method and hepatic fat fraction measured by magnetic resonance imaging in type 2 diabetes patients with non-alcoholic fatty liver disease. RESULTS Canagliflozin significantly reduced body and fat mass, and induced a slight decrease in lean body or muscle mass that did not reach significance at 6 and 12 months. Reductions in fat mass in each body segment (trunk, arms and legs) were evident, whereas those in lean body mass were not. The hepatic fat fraction was reduced from a baseline of 17.6 ± 7.5% to 12.0 ± 4.6% after 6 months and 12.1 ± 6.1% after 12 months (P < 0.0005 and P < 0.005), whereas serum liver enzymes and type IV collagen concentrations improved. From a mean baseline hemoglobin A1c of 8.7 ± 1.4%, canagliflozin significantly reduced hemoglobin A1c after 6 and 12 months to 7.3 ± 0.6% and 7.7 ± 0.7% (P < 0.0005 and P < 0.01). CONCLUSIONS Canagliflozin reduced body mass, fat mass and hepatic fat content without significantly reducing muscle mass.

Heart failure drug treatment.
Rossignol, P, Hernandez, AF, Solomon, SD, Zannad, F
Lancet (London, England). 2019;(10175):1034-1044
Abstract
Heart failure is the most common cardiovascular reason for hospital admission for people older than 60 years of age. Few areas in medicine have progressed as remarkably as heart failure treatment over the past three decades. However, progress has been consistent only for chronic heart failure with reduced ejection fraction. In acutely decompensated heart failure and heart failure with preserved ejection fraction, none of the treatments tested to date have been definitively proven to improve survival. Delaying or preventing heart failure has become increasingly important in patients who are prone to heart failure. The prevention of worsening chronic heart failure and hospitalisations for acute decompensation is also of great importance. The objective of this Series paper is to provide a concise and practical summary of the available drug treatments for heart failure. We support the implementation of the international guidelines. We offer views on the basis of our personal experience in research areas that have insufficient evidence. The best possible evidence-based drug treatment (including inhibitors of the renin-angiotensin-aldosterone system and β blockers) is useful only when optimally implemented. However, implementation might be challenging. We believe that disease management programmes can be helpful in providing a multidisciplinary, holistic approach to the delivery of optimal medical care.

Abstract
BACKGROUND AND OBJECTIVES The sodium glucose cotransporter 2 (SGLT-2) inhibitor dapagliflozin is a novel drug for the treatment of diabetes mellitus. Recent studies suggest that SGLT-2 inhibitors affect phosphate homeostasis, but their effects on phosphate-regulating hormones in patients with diabetic kidney disease are still unclear. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We performed a post-hoc analysis of a double-blind, randomized, crossover trial in patients with type 2 diabetes with early-stage diabetic kidney disease on stable renin-angiotensin-aldosterone system blockade, with an albumin-to-creatinine ratio between 100 and 3500 mg/g, eGFR≥45 ml/min per 1.73 m2, and glycosylated hemoglobin≥7.2% and <11.4%. Patients were randomized to dapagliflozin 10 mg/d or placebo during consecutive 6-week study periods, separated by a 6-week wash-out. We investigated effects on circulating phosphate, calcium, parathyroid hormone (PTH), fibroblast growth factor 23 (FGF23), 25-hydroxyvitamin D (25[OH]D), and 1,25-dihydroxyvitamin D (1,25[OH]2D) levels. RESULTS Thirty-one patients (age 62 years; 23% female) were analyzed. Compared with placebo, dapagliflozin increased serum phosphate by 9% (95% confidence interval, 4% to 15%; P=0.002), PTH increased by 16% (3% to 30%; P=0.01), FGF23 increased by 19% (0.3% to 42%; P=0.05), and serum 1,25(OH)2D decreased by -12% (-25% to 4%; P=0.12). Calcium and 25(OH)D were unaffected. We found no correlation between changes in markers of phosphate homeostasis and changes in eGFR or 24-hour albumin excretion during dapagliflozin treatment. CONCLUSIONS Dapagliflozin increases serum phosphate, plasma PTH, and FGF23. This effect was independent of concomitant changes in eGFR or 24-hour albumin excretion.

Abstract
AIMS: To assess the dapagliflozin exposure-response relationship in Japanese and non-Japanese patients with type 1 diabetes mellitus (T1DM) and investigate if a dose adjustment is required in Japanese patients. MATERIALS AND METHODS Data from two clinical studies were used to develop a non-linear mixed effects model describing the relationship between dapagliflozin exposure (area under the concentration curve) and response (24-hour urinary glucose excretion [UGE]) in Japanese and non-Japanese patients with T1DM. The effects of patient-level characteristics (covariates; identified using a stepwise procedure) on response was also assessed. Simulations were performed using median-normalized covariate values. RESULTS Data from 84 patients were included. Average self-monitored blood glucose (SMBG) at day 7, change from baseline in total insulin dose at day 7, and baseline estimated glomerular filtration rate (eGFR) all had a significant effect on 24-hours UGE, with SMBG being the most influential. Dapagliflozin systemic exposure for matching doses and baseline eGFR was similar between Japanese and non-Japanese patients; however, higher SMBG and a greater reduction in total insulin dose was observed in the Japanese population. When the significant covariates were included, the model fit the data well for both populations, and accurately predicted exposure-response in the Japanese and non-Japanese populations, in agreement with the observed data. CONCLUSIONS There was no difference in dapagliflozin exposure-response in Japanese and non-Japanese patients with T1DM once differences in renal function, glycaemic control and insulin dose reductions between studies were considered. Therefore, no dose adjustment is recommended in Japanese patients with T1DM.
