Xu C, Li H, Xu Q, Zhao K, Hao M, Lin W, Ma X, Gao X, Kuang H. Dapagliflozin ameliorated retinal vascular permeability in diabetic retinopathy rats by suppressing inflammatory factors. J Diabetes Complications 2024; 38:108631. [PMID: 38340519 DOI: 10.1016/j.jdiacomp.2023.108631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 09/28/2023] [Accepted: 10/15/2023] [Indexed: 02/12/2024]
Abstract
BACKGROUND Diabetic retinopathy is a common microvascular complication of diabetes and one of the major causes of blindness in the working-age population. Emerging evidence has elucidated that inflammation drives the key mechanism of diabetes-mediated retinal disturbance. As a new therapeutic drug targeting diabetes, whether dapagliflozin could improve vascular permeability from the perspective of anti-inflammatory effect need to be further explored. METHODS Type 2 diabetic retinopathy rat model was established and confirmed by fundus fluorescein angiography (FFA). ELISA detected level of plasma inflammatory factors and C-peptide. HE staining, immunohistochemistry and western blot detected histopathology changes of retina, expression of retinal inflammatory factors and tight junction proteins. RESULTS Dapagliflozin exhibited hypoglycemic effect comparable to insulin, but did not affect body weight. By inhibiting expression of inflammatory factors (NLRP3, Caspase-1, IL-18, NF-κB) in diabetic retina and plasma, dapagliflozin reduced damage of retinal tight junction proteins and improved retinal vascular permeability. The anti-inflammatory effect of dapagliflozin was superior to insulin. CONCLUSIONS Dapagliflozin improved retinal vascular permeability by reducing diabetic retinal and plasma inflammatory factors. The anti-inflammatory mechanism of dapagliflozin is independent of hypoglycemic effect and superior to insulin.

Abstract
BACKGROUND Sodium-glucose cotransporter-2 inhibitors are an innovative diabetes treatment that lowers blood sugar levels without insulin. A growing body of evidence suggests that blood sugar levels are tightly correlated with uric acid levels in their blood and urine. To alleviate type 2 diabetes (T2DM) suffering, we tested dapagliflozin on serum and urinary uric acid levels of patients with T2DM and measured its efficacy in reducing uric acid levels. METHODS A study was conducted on 60 people with T2DM. Patients were treated with Dapagliflozin doses of 10 mg daily for 3 months. Three months later, we measured body weight, fasting, and postprandial blood glucose levels, Hemoglobin A1C (HbA1c), serum lipids, renal function tests, routine urine, and serum uric acid. RESULTS A number of clinical parameters of T2DM patients were compared to those of healthy subjects of the same age group. A comprehensive analysis of all parameters was conducted to evaluate dapagliflozin's impact. After 90 days of dapagliflozin treatment, serum uric acid levels dropped significantly from 9.0 to 8 mg/dL in the dapagliflozin group, as well as uric acid percentage in urine changed from 16.1 to 23.6 %. After three months of treatment, HbA1C levels decreased from 9.8 % to 8.5 %. CONCLUSION Following treatment with dapagliflozin, the patients' Homeostatic Model Assessment for Insulin Resistance decreased to 4.0. Further, multivariate correlation analysis showed a correlation of serum uric acid with glycemic profile positively. In conclusion, dapagliflozin lowers uric acid levels and increases insulin sensitivity in diabetic patients to improve their glycemic control.

Diabetes Ther 2023; 14:2015-2030. [PMID: 37837581 PMCID: PMC10597985 DOI: 10.1007/s13300-023-01481-7] [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: 08/18/2023] [Accepted: 09/25/2023] [Indexed: 10/16/2023] Open
Abstract
Body composition is related to cardiometabolic disorders and is a major driver of the growing incidence of type 2 diabetes mellitus (T2DM). Altered fat distribution and decreased muscle mass are related to dysglycemia and impose adverse health-related outcomes in people with T2DM. Hence, improving body composition and maintaining muscle mass is crucial in T2DM. Sodium-glucose cotransporter 2 (SGLT2) inhibitors are novel glucose-lowering medications gaining popularity because of their cardiorenal-protective effects and weight-lowering characteristics. However, reports on myopathy secondary to SGLT2 inhibitor treatment raised a safety concern. The importance of maintaining muscle mass in people with T2DM necessitates further investigation to explore the impact of novel medications on body composition. In this review, we discussed current evidence on the impact of SGLT2 inhibitors on body composition in people with T2DM.

Comparison of Sodium-Glucose Cotransporter-2 Inhibitors and Thiazolidinediones for Management of Non-Alcoholic Fatty Liver Disease: A Systematic Review and Meta-Analysis. Clin Res Hepatol Gastroenterol 2023; 47:102111. [PMID: 36931466 DOI: 10.1016/j.clinre.2023.102111] [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: 10/06/2022] [Revised: 02/27/2023] [Accepted: 03/08/2023] [Indexed: 03/19/2023]
Abstract
BACKGROUND The pharmacologic treatment of non-alcoholic fatty liver disease (NAFLD) remains unclear. METHODS Two reviewers searched PubMed, SCOPUS, Cochrane Central and clinicaltrials.gov for randomized controlled trials (RCTs) of patients with NAFLD with or without type 2 diabetes mellitus (T2DM) receiving TZDs vs SGLT2 inhibitors. The primary outcomes were change in alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) and improvement in steatosis and fibrosis. The secondary outcomes were changes in lipid profile, body weight and glycated hemoglobin (HbA1c). Random effects models with continuous outcomes as weighted mean differences (WMD) with 95% confidence intervals (CI) were used. RESULTS Five studies (n= 311 NAFLD patients) were included. Patients treated with SGLT2 inhibitors (n= 156) showed significant decrease in visceral fat area (VFA; WMD 23.45, p<0.00001) and body weight (WMD 4.22, p<0.00001) as compared to those treated with TZDs (n= 155). Patients from both groups showed improvement in AST (WMD 1.21, p= 0.40), ALT (WMD -0.46, p= 0.81), GGT (WMD -0.47, p= 0.84), hepatic fibrosis (WMD 0.11, p= 0.52), LDL (WMD 2.19, p= 0.35), HbA1c (WMD -0.16%, p= 0.20), HOMA-IR (WMD: -0.04, p= 0.91) and FPG (WMD -7.37, p= 0.28) which was equivalent and non-significant. CONCLUSION The improvement in liver enzymes, steatosis and fibrosis caused by SGLT2 inhibitors and TZDs was similar. SGLT2 inhibitors, however, resulted in a significant decrease in VFA and body weight. As weight loss is found to have a positive effect on the resolution of steatosis and fibrosis in NAFLD patients, SGLT2 inhibitors may have the potential to be considered for long-term management, however, further research needs to be conducted to determine the utility of SGLT2 inhibitor class of antidiabetic drugs for effectively treating NAFLD.

Abstract
INTRODUCTION Hypertension is a well-established risk factor for cardiovascular (CV) events in patients with chronic kidney disease (CKD), heart failure, obesity, and diabetes. Despite the usual prescribed antihypertensive therapies, many patients fail to achieve the recommended blood pressure (BP) targets. AREAS COVERED This review summarizes the clinical BP-lowering data presented in major CV and kidney outcome trials for sodium-glucose cotransporter-2 (SGLT2) inhibitors, as well as smaller dedicated BP trials in high-risk individuals with and without diabetes. We have also highlighted potential mechanisms that may contribute to the antihypertensive effects of SGLT2 inhibitors, including natriuresis and hemodynamic changes, a loop diuretic-like effect, and alterations in vascular physiology. EXPERT OPINION The antihypertensive properties of SGLT2 inhibitors are generally modest but may be larger in certain patient populations. SGLT2 inhibitors may have an additional role as an adjunctive BP-lowering therapy in patients with hypertension at high risk of CV disease or kidney disease.

Abstract
AIMS The present study aims to determine the effects of sodium-glucose cotransporter 2 (SGLT-2) inhibitors on the serum uric acid (SUA) levels of patients with type 2 diabetes mellitus (T2DM) in Asia. METHODS PubMed, CENTRAL, Embase and Cochrane Library databases were searched for randomized controlled trials of SGLT-2 inhibitors in patients with T2DM up to 15 July 2021, without language or date restrictions. RESULTS In total, 19 high-quality studies (4218 participants) were included in the present network meta-analysis. All of the included SGLT-2 inhibitors (empagliflozin, dapagliflozin, canagliflozin, ipragliflozin, luseogliflozin and tofogliflozin) significantly decreased SUA levels compared with those of the control [total standard mean difference -0.965, 95% CI (-1.029, -0.901), p = .000, I2 = 98.7%] in patients with T2DM. Subgroup analysis and meta-regression showed that the combined analysis of different inhibitors might lead to heterogeneity of the results. Therefore, among the SGLT-2 inhibitors, the results of the subsequent network meta-analysis revealed that luseogliflozin and dapagliflozin ranked the highest in terms of lowering SUA levels among the SGLT-2 inhibitors. Moreover, the network meta-analysis declared that luseogliflozin (1 and 10 mg) and dapagliflozin (5 mg) led to a superior reduction in SUA in patients with T2DM. CONCLUSIONS SGLT-2 inhibitors could significantly reduce SUA levels in patients with T2DM, particularly luseogliflozin (1 and 10 mg) and dapagliflozin (5 mg) possess the best effects. Therefore, SGLT-2 inhibitors look extremely promising as an antidiabetes treatment option in patients with T2DM with high SUA.

Abstract
AIMS Non-alcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease in Western countries and a common comorbidity with type 2 diabetes (T2D). It lacks effective pharmacotherapy. We aimed to summarize the evidence on the effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors on liver structure and function. MATERIALS AND METHODS Meta-analysis of randomized clinical trials in PubMed, Web of Science and ClinicalTrials.gov from their inception to April 2019. Trials evaluating liver function and/or structure and comparing SGLT2 inhibitors with placebo or other oral antidiabetic drugs in patients with T2D were included. Twenty studies (from 3033) were included. A total of 1950 patients with T2D, with or without NAFLD, were treated with SGLT2 inhibitors for at least 8 weeks, and 1900 patients were used as controls. Independent extraction was carried out by two observers. This study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis. RESULTS SGLT2 inhibitors induced a significant decrease in serum alanine (-7.43U/L, [95%CI -12.14, -2.71], p < 0.01), in aspartate aminotransferases (-2.83U/L, [-4.71, -0.95], p < 0.01), as well as in gamma glutamyl transferase (-8.21U/L, [-9.52, -6.91], p < 0.01), and an increase in total plasma bilirubin (8.19% [0.79, 15.59], p < 0.01), comparing with placebo or other oral antidiabetic drugs. SGLT2 inhibitors treatment was associated with a decrease in liver steatosis (-3.39% [-6.01, -0.77], p < 0.0.1). CONCLUSIONS Treatment with SGLT2 inhibitors improves liver structure and function in patients with T2D. This meta-analysis suggests that SGLT2 inhibitors are a promising pharmacological approach for treatment of NAFLD.

Abstract
OBJECTIVE This study aimed to evaluate the effect of adiposity and fat distribution on the odds of elevated cardiovascular risk factors among adults with type 2 diabetes mellitus. METHODS The present cross-sectional study included 2,427 adults with type 2 diabetes mellitus. Body fat was assessed by dual-energy x-ray absorptiometry. Multivariate-adjusted logistic regression was used to estimate effects of adiposity parameters on elevated hemoglobin A1c (HbA1c , ≥7.0%), hypertension (blood pressure ≥140/90 mmHg), and elevated low-density lipoprotein (LDL) cholesterol (≥2.6 mmol/L). RESULTS The multivariable-adjusted odds ratio (OR) for elevated HbA1c was 0.82 (95% CI: 0.70-0.96) for each SD increase in leg fat mass. The multivariable-adjusted OR for hypertension was 1.15 (95% CI: 1.00-1.32) for each SD increase in android fat mass. Multivariable-adjusted ORs for elevated LDL cholesterol ranged from 1.16 (95% CI: 1.00-1.35) to 1.27 (95% CI: 1.06-1.51) for each SD increase in arm and android fat mass and percentage of total, truncal, arm, and android fat. Each SD increase in BMI, truncal-to-leg fat ratio, and android-to-gynoid fat ratio was significantly associated with increased risks of elevated HbA1c , hypertension, and elevated LDL cholesterol. CONCLUSIONS Subcutaneous fat in the lower body was associated with a more favorable glycemic profile, but not blood pressure or lipid profile, whereas central adiposity was associated with poor control of cardiovascular risk factors among patients with type 2 diabetes mellitus.

Abstract
Aims:
The aim of this study is to provide an overview of several emerging anti-diabetic
molecules.
Background:
Diabetes is a complex metabolic disorder involving the dysregulation of glucose homeostasis
at various levels. Insulin, which is produced by β-pancreatic cells, is a chief regulator of glucose
metabolism, regulating its consumption within cells, which leads to energy generation or storage as glycogen.
Abnormally low insulin secretion from β-cells, insulin insensitivity, and insulin tolerance lead to
higher plasma glucose levels, resulting in metabolic complications. The last century has witnessed extraordinary
efforts by the scientific community to develop anti-diabetic drugs, and these efforts have resulted
in the discovery of exogenous insulin and various classes of oral anti-diabetic drugs.
Objective:
Despite these exhaustive anti-diabetic pharmaceutical and therapeutic efforts, long-term
glycemic control, hypoglycemic crisis, safety issues, large-scale economic burden and side effects remain
the core problems.
Method:
The last decade has witnessed the development of various new classes of anti-diabetic drugs
with different pharmacokinetic and pharmacodynamic profiles. Details of their FDA approvals and
advantages/disadvantages are summarized in this review.
Results:
The salient features of insulin degludec, sodium-glucose co-transporter 2 inhibitors, glucokinase
activators, fibroblast growth factor 21 receptor agonists, and GLP-1 agonists are discussed.
Conclusion :
In the future, these new anti-diabetic drugs may have broad clinical applicability. Additional
multicenter clinical studies on these new drugs should be conducted.

Abstract
Background Raised serum uric acid (SUA) level is commonly observed in patients with type 2 diabetes mellitus (T2DM) and is associated with increased morbidity and mortality. Sodium-glucose cotransporter 2 inhibitor, a novel oral diabetic drug, might exert a potential hypouricemic effect. We evaluated the effects of dapagliflozin on SUA levels in hospitalized T2DM patients with inadequate glycemic control. Methods In this randomized controlled trial, 59 T2DM hospitalized patients with inadequate glycemic control were assigned to the dapagliflozin 10 mg group (n=29) or the control group (n=30). The primary outcome was changes in SUA levels from the baseline to good glycemic control. Additional outcomes included correlations between baseline SUA levels, urinary parameters, and the changes in SUA levels. This trial is registered in the Chinese Clinical Trial Registry (number ChiCTR1800015830). Results Compared to baseline level, SUA levels had significantly decreased in both groups (P<0.001 for the dapagliflozin group and P=0.013 for the control group). Mean changes from baseline in SUA levels for dapagliflozin vs the control group were 68.03 vs 25.90 μmol/L (P=0.0406). Adjusted mean SUA levels were lower in the dapagliflozin group (273.28 vs 307.57 μmol/L; P=0.0089). In T2DM patients treated with dapagliflozin, the decrease in SUA levels was positively correlated with baseline SUA levels (P<0.0001) but not correlated with changes in 24-hour urine volume, 24-hour urine glucose, or 24-hour urinary uric acid. Conclusion Dapagliflozin could improve glycemic control and lower SUA levels in hospitalized patients with uncontrolled T2DM. Longer-time trials are required to further demonstrate the hypouricemic effect of dapagliflozin and explore the potential underlying mechanisms.

Abstract
Patients with growth hormone deficiency (GHD) have an increased risk of atherosclerosis and vascular mortality. Evidence suggests that endothelial dysfunction is involved in all stages of atherogenesis. This study examined the effect of growth hormone (GH) replacement therapy on diacron-reactive oxygen metabolites (d-ROMs) and endothelial function in Japanese patients with GHD, using peripheral arterial tonometry. This was an open-label, prospective, case-control study. Nine patients with GHD who had not previously received any GH replacement therapy were enrolled. The following parameters were evaluated at baseline (before treatment), and after 24 weeks of GH replacement therapy: endothelial function using the reactive hyperemia index (RHI; EndoPAT® system), d-ROMs, blood pressure, and fasting lipid levels. Plasma GH and insulin-like growth factor-1 (IGF-1) levels were measured at baseline and after 24 weeks of GH replacement therapy. We also enrolled eight controls with pituitary disease but no GH deficiency. Over 24 weeks of GH replacement therapy, the serum IGF-1 levels normalized with significant improvement in the RHI (from 1.65 ± 0.33 to 1.92 ± 0.26, p < 0.05) and decreased d-ROM levels (from 356.8 ± 64.1 to 303.1 ± 43.3 U.CARR, p < 0.05). There were no significant improvements in the RHI or d-ROM levels in controls. GH replacement therapy in Japanese patients with GHD may be mediated by the reduced oxidative stress and the d-ROMs associated with the treatment.
