The mechanisms of the renoprotective effects of sodium-glucose cotransporter 2 inhibitors are unknown. This study aimed to explore the effect and mechanism of tofogliflozin on urinary albumin by administration, withdrawal, and re-administration.

Individuals with type 2 diabetes mellitus and stage 2 or 3 diabetic nephropathy were enrolled. Tofogliflozin was administered for 24 weeks, withdrawn for 12 weeks (withdrawal period), and re-administered for 24 weeks. The primary endpoint was the change in urinary albumin/creatinine ratio (UACR). The secondary endpoints included hemoglobin A1c (HbA1c), hepatic biomarkers, lipid profiles, physical examinations, and blood counts.

A total of 47 individuals were enrolled. UACR significantly decreased throughout the observation period. It also significantly decreased, increased, and again decreased during the period of the 1st administration, withdrawal, and re-administration, respectively. HbA1c, body weight, waist circumference, and systolic blood pressure also showed the same tendency. Aspartate aminotransferase and alanine aminotransferase significantly decreased throughout the observation period, but did not increase during the withdrawal period.

Urinary albumin improved during the administration of tofogliflozin and worsened during its withdrawal, suggesting the reversibility of its renoprotective effect. The administration of tofogliflozin should be continued to avoid the reversal of glycemic control, renoprotective effects, and other beneficial effects.

SGLT-2 inhibitors (SGLT-2i) provide good glycaemic control and weight loss, ensuring clinically relevant cardiorenal benefits in subjects with and without type 2 diabetes (T2D); however, their use is related to an enhanced risk of urogenital infections, mainly in female subjects. We performed a prospective observation to assess incidence of urogenital complications in male sex new users of gliflozins.

In the 2021-2023 years, solely based on clinical indication, we started such therapy in 272 male T2D subjects; follow up visits were performed after about 1 year.

At follow up, 90 subjects had discontinued SGLT-2i; 36 of them (40 %) due to onset of urogenital symptoms. We observed 6 cases of phimosis. Subjects who discontinued the treatment due to these side effects had a higher BMI and a better eGFR at baseline and they were less frequently treated with DPP-IV inhibitors.

A proper evaluation of the patient's phenotype might be useful in identifying subjects less prone to develop side effects driving SGLT-2i discontinuation; the combined use of SGLT-2i and DPP-IV inhibitors appears to be associated to a better long-term compliance to therapy in men.

The four-drug regimen for heart failure with reduced ejection fraction (HFrEF) significantly reduces the risks of hospitalization and mortality. To identify key adverse drug events (ADEs) warranting attention with this regimen, we conducted a real-world pharmacovigilance analysis based on the FDA Adverse Event Reporting System (FAERS) events.

We collected ADE reports of the four-drug regimen from FAERS that matched this regimen over a 10-year period. Disproportionality analysis and subgroup analysis were performed using four algorithms. Time-to-onset (TTO) analysis was used to assess the temporal risk patterns of ADE occurrence. Lastly, logistic regression was applied to investigate the relationship-value between patient characteristics and ADEs.

A total of 1,237 cases with 6,580 ADE reports were collected. Disproportionality analysis identified the most frequent ADEs as hypotension, acute kidney injury (AKI), and hyperkalemia. TTO analysis revealed a median TTO of 39 days for all important medical events, and the median TTO for AKI was 28 days, both fitting an early failure curve.

In the comprehensive management of HFrEF with the four-drug regimen, in addition to routine monitoring of ADEs such as hypotension and hyperalemia, early-onset AKI should be a particular focus.

Post hoc analyses of clinical trials suggest that sodium-glucose cotransporter-2 inhibitors (SGLT-2i) lower the risk of hyperkalemia and facilitate the use of renin-angiotensin system inhibitors (RASi) in people with type 2 diabetes. Whether this is also observed in routine care is unclear. We investigated whether SGLT-2i lowered the risk of hyperkalemia and RASi discontinuation as compared to dipeptidyl peptidase 4 inhibitors (DPP-4i).

Using the target trial emulation framework, we studied adults with type 2 diabetes (T2D) who started SGLT-2i or DPP-4i in Stockholm, Sweden (2014-2021). The outcomes were incident hyperkalemia (potassium >5.0 mmol/l), mild hyperkalemia (potassium >5-≤5.5 mmol/l), and moderate to severe hyperkalemia (potassium >5.5 mmol/l). Among RASi users, we studied time to RASi discontinuation through evaluation of pharmacy fills. Cox regression with inverse probability of treatment weighting was used to estimate per-protocol hazard ratios (HRs).

In total, 29 849 individuals (15 326 SGLT-2i and 14 523 DPP-4i initiators) were included (mean age 66 years, 37% women). About one-third of participants in each arm discontinued treatment within 1 year. Compared with DPP-4i, SGLT-2i use was associated with a lower rate of hyperkalemia (HR 0.77; 95% CI: 0.64-0.93), including both mild (0.76; 0.62-0.93) and moderate/severe (0.53; 0.40-0.69) hyperkalemia events. Of 19 116 participants who used RASi at baseline, 7% discontinued therapy. Initiation of SGLT-2i vs. DPP-4i was not associated with the rate of RASi discontinuation (0.97; 0.83-1.14). Results were consistent in intention-to-treat analysis and across strata of sex, cardiovascular disease, use of MRA, and use of RASi.

In patients with diabetes managed in routine clinical care, the use of SGLT-2i was associated with lower rates of hyperkalemia compared with DPP-4i. Possibly because of a relatively high rate of treatment discontinuations, this was not accompanied by higher persistence on RASi therapy.

Regular coffee intake is recognized as a protective factor against various chronic diseases, particularly diabetes. However, the correlation between coffee intake-both the act of drinking coffee and the amount consumed-and diabetic kidney disease (DKD) remains uncertain. The goal of this study is to measure the correlation between coffee intake and DKD.

This cross-sectional study was based on data from the 2007 to 2016 National Health and Nutrition Examination Survey (NHANES). DKD was characterized by the coexistence of diabetes combined with impaired glomerular filtration rate (eGFR < 60 mL/min/1.73 m2) or ACR ≥ 30 mg/g. Weighted logistic regression and restricted cubic spline (RCS) analyses were adopted to evaluate the correlation between coffee intake and DKD. The subgroup analyses were implemented to assess the reliability of the results.

The study included 13,177 participants, representing a weighted population of 125,388,198 individuals. Among them, 8198 (64%) participants consumed coffee and 1430 (7.6%) were classified as having DKD. After controlling for covariates, multivariable logistic regression showed a negative correlation between moderate coffee intake and DKD (OR = 0.68; 95% CI: 0.55-0.83; P < 0.001). The RCS analysis suggested a U-shaped, non-linear correlation between coffee intake and DKD (P overall = 0.013; P nonlinear = 0.047). The subgroup analyses further supported the stability and reliability of these findings.

The results indicate a U-shaped correlation between coffee intake and diabetic kidney disease.

Kidney transplantation is the optimal treatment for end-stage kidney disease, but many patients also have diabetes mellitus. This study compares long-term outcomes between new users of sodium-glucose cotransporter-2 inhibitors (SGLT2i) and dipeptidyl peptidase-4 inhibitors (DPP-4i) in kidney transplant recipients with diabetes mellitus. Data from the TriNetX Collaborative Network, including 89,710 patients with diabetes mellitus who underwent kidney transplantation between January 1, 2015, and June 30, 2023, were analyzed. From this cohort, 1410 matched pairs of SGLT2i and DPP-4i users were selected based on propensity scores. The results showed that SGLT2i users had a lower risk of dialysis (hazards ratio: 0.694) and all-cause mortality (hazards ratio: 0.687) compared with DPP-4i users. There were no significant differences in the risk of posttransplant infections, transplant rejection, or hospitalization between the 2 groups. Additionally, SGLT2i users had significantly lower cumulative incidences of dialysis and mortality. In conclusion, this study, using data from TriNetX, demonstrated that SGLT2i treatment in kidney transplant recipients with diabetes mellitus is associated with lower risks of dialysis and mortality, suggesting it may help preserve kidney function and improve survival in this population.

To compare the risk of composite peripheral artery disease (PAD) surgical outcome, including peripheral revascularization and amputation procedures, between new users of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and dipeptidyl peptidase 4 inhibitors (DPP-4is).

This retrospective cohort study of U.S. veterans age ≥18 years with diabetes who received care from the Veterans Health Administration was performed from 1 October 2000 to 31 December 2021. Data were linked to Medicare, Medicaid, and the National Death Index. New use of SGLT2i or DPP-4i medications as an add-on to metformin, sulfonylurea, or insulin treatment alone or in combination was evaluated for an association with PAD surgical procedure for peripheral revascularization and amputation. A Cox proportional hazards model for time-to-PAD event analysis compared the risk of a PAD event between SGLT2is and DPP-4is in a propensity score-weighted cohort with a competing risk of death and allowance for events to occur up to 90 days or 360 days after stopping SGLT2is.

The weighted cohort included 76,072 SGLT2i vs. 75,833 DPP-4i use episodes. The median age was 69 years, HbA1c was 8.4% (interquartile range [IQR] 7.5-9.4%), and the median diabetes duration was 10.1 (IQR 6.6-14.6) years. There were 874 and 780 PAD events among SGLT2i and DPP-4i users, respectively, for an event rate of 11.2 (95% CI 10.5-11.9) and 10.0 (9.4-10.6) per 1,000 person-years (adjusted hazard ratio [aHR] 1.18 [95% CI 1.08-1.29]). When PAD events were allowed for 360 days after SGLT2i use ended, the aHR was 1.16 (95% CI 1.06-1.26).

SGLT2i as an add-on diabetes therapy was associated with an increased cause-specific hazard of PAD surgeries compared with DPP-4i.

Diabetic kidney disease (DKD) represents the predominant and severe microvascular complication associated with diabetes, frequently culminating in End-Stage Kidney Disease (ESKD). The escalating prevalence of diabetes has correspondingly led to a rise in DKD incidence, imposing significant challenges on both individuals and society. The etiology of DKD is multifaceted and remains devoid of definitive therapeutic interventions. This article examines the pharmacological actions and mechanisms of different drugs used for the prevention and treatment of DKD that are currently in clinical use or undergoing development. The goal is to offer insights for early intervention based on therapeutic combinations to potentially slow kidney disease progression.

Although there is concern about the association of sodium-glucose cotransporter-2 inhibitor (SGLT2i) use with musculoskeletal pain, hypovolemia, and urinary tract infection in patients with severe chronic kidney disease (CKD), information on these adverse events is insufficient. The aim of this systematic review and meta-analysis was to assess whether SGLT2i increases the risk of urinary tract infection, hypovolemia, and musculoskeletal pain in these patients.

MEDLINE via PubMed, the Cochrane Central Register of Controlled Trials, and the ClinicalTrials.gov website were comprehensively searched to extract all relevant studies. Randomized controlled trials (RCTs) were selected that compared SGLT2i versus placebo, and the study populations consisted of patients with CKD stage 3 or higher.

Eleven studies were eligible for inclusion. SGLT2i tended to increase the risk of hypovolemia [risk ratio (RR) 1.15, 95% confidence interval (CI) 0.98-1.35, P = 0.08, high certainty] but did not increase the risk of urinary tract infection (RR 1.03, 95% CI 0.94-1.12, P = 0.56, high certainty) or musculoskeletal pain (RR 0.69, 95% CI 0.41-1.17, P = 0.17, high certainty). Subgroup analysis of patients with heart disease was performed for the outcome of hypovolemia, and the results showed a significant difference in hypovolemia (RR 1.21, 95% CI 1.06-1.39, P < 0.01, moderate certainty) between SGLT2i and placebo.

This meta-analysis suggests that SGLT2i may increase the risk of hypovolemia in patients with moderate to severe CKD and heart disease but is not associated with urinary tract infection or musculoskeletal pain.

Diabetic nephropathy is a severe chronic complication characterized by cytotoxicity, inflammation, and fibrosis, ultimately leading to renal failure. This study systematically investigated the effects of the PARP1 inhibitor PJ-34 on high glucose-induced cytotoxicity, inflammation, and fibrosis in HK-2 cells, as well as its improvement on neuropathic pain response and transforming growth factor β (TGFβ) expression in a type 1 diabetes mellitus diabetic nephropathy mouse model. Through cellular and animal experiments, we observed that PJ-34 significantly enhanced the proliferative capacity of cells damaged by high glucose, reduced apoptosis, and decreased the release of proinflammatory factors TGFα, interleukin-6, and interleukin-1β. In the type 1 diabetes mellitus nephropathy mouse model, the administration of PJ-34 substantially improved parameters of neuropathic pain, alleviated renal tissue damage, reduced indicators of renal functional impairment-inhibited renal fibrosis, and reduced the key protein expression in the epithelial-mesenchymal transition process, acting through the regulation of the TGFβ/Smads signaling pathway. This study elucidated the mechanism of action of the PARP1 inhibitor PJ-34 as a potential therapeutic agent for diabetic nephropathy, offering a novel strategy for its treatment.

This study aims to evaluate the incidence of hyperkalemia and serum potassium levels associated with the use of sodium-glucose cotransporter-2 inhibitors (SGLT-2i), renin-angiotensin-aldosterone system inhibitors (RAASi) and concurrent use of these medications in individuals with diabetic kidney disease (DKD).

A comprehensive systematic search was performed in EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Scopus, and PubMed database, covering studies up to March 2024. Relevant randomized controlled trials (RCT) included adults with DKD who were treated with SGLT-2i and RAASi or their combination, with a minimum follow-up duration of 12 weeks. The primary outcomes assessed were the incidence of hyperkalemia and serum potassium levels were the primary outcomes assessed. The surface under the cumulative ranking curves (SUCRA) was utilized for ranking purposes.

The study included 36 trials, encompassing 45,120 participants, comparing various interventions. SGLT-2i (SUCRA = 88.5%) was found to significantly reduce the risk of hyperkalemia. In contrast, the combination of ACEI/ARB + MRA (SUCRA = 5.7%) increased the risk of hyperkalemia. However, when SGLT-2i was added to the ACEI/ARB + MRA regimen, the incidence of hyperkalemia was found to decrease. Subgroup analyses on MRA showed that ACEI/ARB + spironolactone posed the highest risk of hyperkalemia. ACEI/ARB + SGLT-2i mitigated serum potassium level.

SGLT-2i was effective in reducing the incidence of hyperkalemia incidence, whereas a combination of ACEI/ARB and MRA might elevate the incidence of hyperkalemia in individuals with DKD.

No clear consensus exists regarding the safest anti-diabetic drugs with the least adverse events on bone health. This umbrella systematic review therefore aims to assess the published meta-analysis studies of randomized controlled trials (RCTs) conducted in this field.

All relevant meta-analysis studies of RCTs assessing the effects of anti-diabetic agents on bone health in patients with diabetes mellitus (DM) were collected in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). English articles published until 15 March 2023 were collected through the search of Cochrane Library, Scopus, ISI Web of Sciences, PubMed, and Embase using the terms "Diabetes mellitus", "anti-diabetic drugs", "Bone biomarker", "Bone fracture, "Bone mineral density" and their equivalents. The methodological and evidence quality assessments were performed for all included studies.

From among 2220 potentially eligible studies, 71 meta-analyses on diabetic patients were included. Sodium-glucose cotransporter-2 inhibitors (SGLT-is) showed no or equivalent effect on the risk of fracture. Dipeptidyl peptidase-4 inhibitors (DPP-4is) and Glucagon-like peptide-1 receptor agonists (GLP-1Ras) were reported to have controversial effects on bone fracture, with some RCTs pointing out the bone protective effects of certain members of these two medication classes. Thiazolidinediones (TZDs) were linked with increased fracture risk as well as higher concentrations of C-terminal telopeptide of type I collagen (CTx), a bone resorption marker.

The present systematic umbrella review observed varied results on the association between the use of anti-diabetic drugs and DM-related fracture risk. The clinical efficacy of various anti-diabetic drugs, therefore, should be weighed against their risks and benefits in each patient.

This study aimed to investigate the association between the utilization of Sodium-dependent glucose cotransporters inhibitors (SGLT2i) in real-world settings and kidney outcomes in patients with type 2 diabetes (T2D) and chronic kidney disease (CKD) in mainland China.

In a retrospective analysis of electronic medical records from West China Hospital of Sichuan University, patients with T2D and CKD were included. Patients were divided into two groups, those initiating treatment with SGLT2i and those receiving other glucose-lowering drugs (oGLDs). The primary focus lies in examining the impact of SGLT2i on the decline slope of eGFR and major kidney events in these patients.

We enrolled 944 patients diagnosed with both T2D and CKD. Out of these, 605 patients were prescribed SGLT2i, while the remaining 339 patients received oGLDs. The median follow-up duration were 16.8 months and 20.6 months, respectively. Throughout the follow-up period, we observed a significant decrease in the rate of eGFR decline in patients using SGLT2i (4.94 mL/min/1.73 m2 per year reduction compared to oGLDs, 95% CI: 4.73-5.15). A total of 101 kidney composite endpoint events occurred, with 31 events in the SGLT2i group and 70 events in the oGLDs group. The use of SGLT2i was associated with a 65% decrease in the risk of kidney composite endpoint events (hazard ratio 0.35, 95% CI 0.19-0.63).

In clinical practice, SGLT2i have shown favorable effects on kidney prognosis in patients with T2D and CKD in mainland China. These effects remain consistent across patients with varying risks of CKD progression.

To assess the cost-effectiveness of diabetic nephropathy treatment with sodium-glucose cotransporter-2 (SGLT2) inhibitors in Japanese clinical practice, considering diabetes-related complications.

A population-based Monte Carlo simulation was used to estimate the cost-effectiveness for people with diabetic nephropathy who initiated pharmacotherapy with an SGLT2 inhibitor plus conventional treatment or conventional treatment alone, based on quality-adjusted life-years (QALYs) and healthcare costs. The Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation study (CREDENCE) and the Japanese Society for Dialysis Research statistical survey were the primary sources of probability and mortality, while Japanese Health Insurance Claims Data were the cost source. The state transition model included diabetic nephropathy, hospitalization due to cardiovascular disease, dialysis, and death. One-way and probabilistic sensitivity analyses were used to explore model uncertainty.

Using the threshold of JPY 5 000 000 per QALY, SGLT2 inhibitor plus conventional treatment was more cost-effective than conventional treatment alone, with an incremental cost-effectiveness ratio of JPY 654 309 per QALY. Treating 100 000 people, SGLT2 inhibitor plus conventional treatment prevented 2234 deaths and reduced 5793 fewer heart failure cases, 3967 fewer myocardial infarctions and stroke events. Sensitivity analysis affirmed the robustness of these results for patients aged under 70 years.

The SGLT2 inhibitor treatment appeared to be cost-effective for the overall population of our study and particularly for younger patients (<70 years old). For older patients (≥70 years old), the cost-effectiveness was less clear and may require further evaluation. Decision-makers should consider this age-based heterogeneity when making recommendations about SGLT2 inhibitor treatment.

Sodium-dependent glucose transporter 2 inhibitors (SGLT2i) have been increasingly used with proven efficacy in patients with heart failure (HF), regardless of diabetes status. Grubić Rotkvić et al recently published an observational study on SGLT2i therapy in patients with type 2 diabetes mellitus and asymptomatic HF. They found that the use of SGLT2i led to reduced cardiac load and improved cardiovascular performance, reinforcing the evolving paradigm that SGLT2i are not merely glucose-lowering agents but are integral to the broader management of cardiovascular risk in patients with type 2 diabetes mellitus. The study by Grubić Rotkvić et al contributes to the growing body of literature supporting the early use of SGLT2i in patients with diabetic cardiomyopathy, offering a potential strategy to mitigate the progression of HF. Future larger studies should be conducted to confirm these findings, and explore the long-term cardiovascular benefits of SGLT2i, particularly in asymptomatic patients at risk of developing HF.

Studies on the correlation of exposure to metals with diabetic kidney disease (DKD) is scarce, especially concerning the impact of mixed metals on DKD. This study aimed to explore the association of blood heavy metals with DKD risk among type 2 diabetes mellitus (T2DM) patients. This cross-sectional study enrolled patients with T2DM in NHANES 2011-2020. ICP‒MS was applied to detect five metals, namely, Pb, Cd, Hg, Se and Mn, in blood. At the same time, the impacts of exposure to single and mixed metals on DKD were assessed using multivariable logistic regression, WQS, and BKMR models. The relationship was examined based on age, sex, BMI, hypertension, smoking status and PIR. Totally 2362 participants were enrolled for final analysis. Among them, 634 (26.84%) patients undergoing T2DM had DKD. Logistic regression indicated that, Pb (Q4: OR [95% CI]: 1.557 [1.175, 2.064]) was related to DKD when all covariates were adjusted. The WQS analysis, which was set in a positive directional mode, suggested that Pb was correlated positively with a higher incidence of DKD. In BKMR analysis, linear dose‒response curves were generated for Pb when fixing the other metals in the 50th percentile. In addition, exposure to mixed metals was significantly positively related to DKD. Subgroup analysis during logistic regression demonstrated that Pb was significantly and positively related to DKD in females, over 50 years, those with over 25 kg/m2, no hypertension, no smoking status and under PIR. Serum albumin (ALB) did not regulate the indirect impact of blood Pb on DKD risk. The results showed that the increased mixed metal concentration may lead to an increased DKD risk among patients with T2DM. Blood Pb is positively related to the DKD risk in diabetic patients, especially, in females, over 50 years, those with over 25 kg/m2, no hypertension, no smoking status and under PIR in T2DM patients. According to our observations, Pb absorption at least slightly influences DKD occurrence and progression. More studies are needed to validate the results in this work and illustrate the relevant biological mechanism.

This meta-analysis was designed to investigate cardio-renal outcomes and safety of sodium-glucose cotransporter-2 inhibitors (SGLT2i) as a therapeutic option among chronic kidney disease(CKD) patients with GFR < 60 mL/min/1.73 m2, regardless of their diabetic status.

We conducted a full-scale search from MEDLINE, EMBASE and the Cochrane Library database to identify eligible studies up to Jun 2024. All randomized controlled trials (RCTs) comparing cardio-renal outcomes and/or safety of SGLT2i in CKD patients with eGFR < 60 mL/min/1.73 m2 were involved. The relative risk (RR) and 95% confidence interval (CI) for primary outcomes and adverse events were computed by random-effects mode. We used I2 statistic to analyze heterogeneity. Publication bias was assessed by Egger's test.

Our study incorporated 17 RCTS, including 27,928 patients. In CKD patients with eGFR < 60 mL/min/1.73 m2, SGLT2i decreased risks of cardiovascular events (seven studies, 17,355 participants, RR 0.77, 95% CI 0.70-0.84), hospitalization for heart failure (HHF) (seven studies, 17,869 participants, RR 0.73, 95% CI 0.65-0.82), cardiovascular death (eight studies, 23,079 participants, RR 0.81, 95% CI 0.74 to 0.88) and renal composite outcomes (eight studies, 22,525 participants, RR 0.70, 95% CI 0.61-0.80) with lower risks of any serious adverse effects(fourteen studies, 19,654 participants, RR 0.91, 95% CI 0.87-0.95), hypoglycemia (nine studies, 16,412 participants, RR 0.91, 95% CI 0.84-0.98), hyperkalemia (four studies, 2693 participants, RR 0.68, 95% CI 0.51-0.93) and acute renal injury (five studies, 5424 participants, RR 0.79, 95% CI 0.65-0.95) compared to placebo. SGLT2i also slowed eGFR decline (total slopes: five studies, 10,370 participants, mean difference 1.17, 95%CI 0.86-1.49; chronic slopes: four studies, 8459 participants, mean difference 2.12, 95%CI 1.64-2.61). Further subgroup analyses revealed that SGLT2i decreased relative risks of cardiovascular outcomes(three studies, 1075 participants, RR 0.76, 95% CI 0.54-0.82), HHF(four studies, 1280 participants, RR 0.74, 95% CI 0.55-1.00) and renal composite outcomes (six studies,4375 participants, RR 0.78, 95% CI 0.68-0.88) with no increased adverse events in the CKD 4 patients.

SGLT2i significantly improved cardio-renal outcomes and were generally safe in CKD patients with eGFR < 60 mL/min/1.73 m2 and with eGFR < 30 mL/min/1.73 m2. Future large-scale RCTs are needed to confirm the robustness of these results.

The objective of this study is to investigate the association between diabetic kidney disease (DKD) and various adiposity indexes, including the visceral adiposity index (VAI), lipid accumulation product index (LAPI), visceral fat area (VFA), and subcutaneous fat area (SFA) in type 2 diabetes mellitus (T2DM) patients. 1176 T2DM patients was stratified into normoalbuminuria (NO), microalbuminuria (MI), and macroalbuminuria (MA) groups based on their urinary albumin-creatinine ratio (UACR) levels. To analyse the correlation between DKD and VAI, LAPI, VFA, and SFA. Multiple linear, restricted cubic spline (RCS), subgroup analyses, and multinomial logistic regression were employed. After adjusting for confounding variables, UACR levels were positively associated with VAI, LAPI, and VFA. RCS curves demonstrated a J-shaped dose-response relationship between VAI and LAPI levels with UACR levels, while a linear correlation was observed between UACR levels and VFA. Using the NO and MI as reference groups, the MA group was analysed as the observational group. DKD severity was positively associated with VAI, LAPI and VFA. When evaluating DKD prognostic risk, with the low-risk and medium-risk groups serving as reference categories, a significant positive correlation was identified with prognostic risk and VAI, LAPI, and VFA in the high-risk or very high-risk groups. In patients with T2DM, DKD severity and prognostic risk were positively correlated with VAI, LAPI, and VFA levels.

People with type 2 diabetes mellitus (T2DM) are at higher risk of developing cardiovascular disease, heart failure, chronic kidney disease, and premature death than people without diabetes. Therefore, treatment of diabetes aims to reduce these complications. Sodium-glucose co-transporter 2 (SGLT2) inhibitors have shown beneficial effects on cardiorenal and metabolic health beyond glucose control, making them a promising class of drugs for achieving the ultimate goals of diabetes treatment. However, despite their proven benefits, the use of SGLT2 inhibitors in eligible patients with T2DM remains suboptimal due to reports of adverse events. The use of SGLT2 inhibitors is particularly limited in older patients with T2DM because of the lack of treatment experience and insufficient long-term safety data. This article comprehensively reviews the risk-benefit profile of SGLT2 inhibitors in older patients with T2DM, drawing on data from prospective randomized controlled trials of cardiorenal outcomes, original studies, subgroup analyses across different age groups, and observational cohort studies.

The association between sodium-glucose cotransporter-2 (SGLT2) inhibitors and the risk of urogenital infections remains controversial. This study aimed to investigate the association between SGLT2 inhibitors and the incidence of perineal soft tissue infections, including Fournier's gangrene (FG), genital bacterial infections, and urinary tract infections (UTIs), using administrative claims data in Japan.

In this retrospective cohort study, we utilized the JMDC Claims Database. The study included patients aged 18 years or older diagnosed with type 2 diabetes mellitus, identified by a diagnostic code, who received new prescriptions for SGLT2 inhibitors or dipeptidyl peptidase 4 (DPP-4) inhibitors between April 2014 and August 2020. Using one-to-one propensity score (PS) matching, we compared the incidence of perineal soft tissue infections, including FG, genital bacterial infection, and UTIs between groups treated with SGLT2 and DPP-4 inhibitors. Hazard ratios (HR) and their 95% confidence intervals (CI) were estimated using the Cox proportional hazards model.

We identified 34,897 patients in the SGLT2 inhibitor group and 135,311 patients in the DPP-4 inhibitor group. After one-to-one PS matching, 31,665 pairs were generated. The mean age of the patients was 51 years, with approximately 70% being male. The use of SGLT2 inhibitors was associated with a decreased risk of UTI (HR 0.90, 95% CI 0.83-0.98) and an increased risk of genital bacterial infection (HR 1.23, 95% CI 1.03-1.46) compared to DPP-4 inhibitors. However, no significant association was observed with perineal soft tissue infection (HR 1.05, 95% CI 0.61-1.81).

SGLT2 inhibitors were associated with a reduced risk of UTI and an increased risk of genital bacterial infection. They showed no significant association with perineal soft tissue infection when compared to DPP-4 inhibitors. Future research should explore broader demographics, focusing on the elderly and achieving gender balance, to gain a comprehensive understanding of infection risks.

To provide an update on the effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors on stroke in patients with type 2 diabetes (T2D).

PubMed, Embase, and Cochrane Library were systematically searched for randomized controlled trials (RCTs) comparing SGLT2 inhibitors versus placebo or other therapies in patients with T2D and reporting stroke endpoint. We computed the risk ratios (RRs) to binary endpoints, with 95 % confidence intervals (CIs).

A total of 71 RCTs and 105,914 patients were included, of whom 62,488 (59 %) were randomized to the SGLT2 inhibitors group. The follow-up ranged from 12 weeks to 4.2 years. There were no significant differences between groups in all types of stroke (RR 0.96; 95 % CI 0.89-1.04), ischemic stroke (RR 0.89; 95 % CI 0.76-1.04), and transient ischemic attack (RR 0.96; 95 % CI 0.79-1.16). Patients on SGLT2 inhibitors experienced lower rates of hemorrhagic stroke (RR 0.62; 95 % CI 0.39-0.98). In the subgroup analysis of the type of drug, sotagliflozin significantly reduced all types of stroke (RR 0.74; 95 % CI 0.56-0.97).

In this meta-analysis of 71 RCTs comprising 105,914 patients with T2D, SGLT2 inhibitors were not associated with a reduced risk of stroke and transient ischemic attack compared to placebo or other therapies; however, there was a trend toward reduced risk of hemorrhagic stroke. Among all SGLT2 inhibitors, sotagliflozin significantly reduced the risk of stroke.

Diabetic kidney disease (DKD) is one of the leading causes of end-stage renal disease worldwide and significantly increases the risk of premature death due to cardiovascular diseases. Elevated urinary albumin levels are an important clinical feature of DKD. Effective control of albuminuria not only delays glomerular filtration rate decline but also markedly reduces cardiovascular disease risk and all-cause mortality. New drugs for treating DKD proteinuria, including sodium-glucose cotransporter two inhibitors, mineralocorticoid receptor antagonists, and endothelin receptor antagonists, have shown significant efficacy. Auxiliary treatment with proprietary Chinese medicine has also yielded promising results; however, it also faces a broader scope for development. The mechanisms by which these drugs treat albuminuria in patients with DKD should be described more thoroughly. The positive effects of combination therapy with two or more drugs in reducing albuminuria and protecting the kidneys warrant further investigation. Therefore, this review explores the pathophysiological mechanism of albuminuria in patients with DKD, the value of clinical diagnosis and prognosis, new progress and mechanisms of treatment, and multidrug therapy in patients who have type 2 diabetic kidney disease, providing a new perspective on the clinical diagnosis and treatment of DKD.

Extracellular matrix (ECM) stiffness is closely related to the progress of diabetic cardiomyopathy (DCM) and the response of treatment of DCM to anti-diabetic drugs. Dapagliflozin (Dapa) has been proven to have cardio-protective efficacy for diabetes and listed as the first-line drug to treat heart failure. But the regulatory relationship between ECM stiffness and treatment efficacy of Dapa remains elusive.

This work investigated the effect of ECM stiffness on DCM progression and Dapa efficacy using both in vivo DCM rat model and in vitro myocardial cell model with high glucose injury. First, through DCM rat models with various levels of myocardial injury and administration with Dapa treatment for four weeks, the levels of myocardial injury, myocardial oxidative stress, expressions of AT1R (a mechanical signal protein) and the stiffness of myocardial tissues were obtained. Then for mimicking the stiffness of myocardial tissues at early and late stages of DCM, we constructed cell models through culturing H9c2 myocardial cells on the polyacrylamide gels with two stiffness and exposed to a high glucose level and without/with Dapa intervention. The cell viability, reactive oxygen species (ROS) levels and expressions of mechanical signal sensitive proteins were obtained.

The DCM progression is accompanied by the increased myocardial tissue stiffness, which can synergistically exacerbate myocardial cell injury with high glucose. Dapa can improve the ECM stiffness-induced DCM progression and its efficacy on DCM is more pronounced on the soft ECM, which is related to the regulation pathway of AT1R-FAK-NOX2. Besides, Dapa can inhibit the expression of the ECM-induced integrin β1, but without significant impact on piezo 1.

Our study found the regulation and effect of biomechanics in the DCM progression and on the Dapa efficacy on DCM, providing the new insights for the DCM treatment. Additionally, our work showed the better clinical prognosis of DCM under early Dapa intervention.

Diabetic kidney disease (DKD), one of the microvascular complications in patients with diabetes mellitus, is a common cause of end-stage renal disease. Cellular senescence is believed to be an essential participant in the pathogenesis of DKD. Although there is evidence that Alpiniae oxyphyllae fructus (AOF) can ameliorate DKD progression and organismal senescence, its ability to ameliorate renal cellular senescence in DKD as well as active components and molecular mechanisms remain to be explored.

This study aimed to investigate the role of AOF in the treatment of cellular senescence in DKD and to explore its active components and potential molecular mechanisms.

The pharmacological efficacy of AOF in ameliorating cellular senescence in DKD was assessed by establishing DKD mouse models and HK-2 cells under high glucose stress. UHPLC-QTOF-MS was used to screen the active compounds in AOF, which were used in conjunction with network pharmacology to predict the molecular mechanism of AOF in the treatment of cellular senescence in DKD.

In vivo experiments showed that AOF reduced GLU, mAlb, Scr, BUN, MDA, SOD levels, and ameliorated renal pathological damage and renal cell senescence in DKD mice. In vitro experiments showed that AOF-containing serum improved the decline in HK-2 cell viability and alleviated cellular senescence under high glucose intervention. The results of the UHPLC-QTOF-MS screened 26 active compounds of AOF. The network pharmacological analyses revealed that Cubebin, 2',6'-dihydroxy-4'-methoxydihydrochalcone, Chalcone base + 3O,1Prenyl, Batatasin IV, and Lucidenolactone were the five core compounds and TP53, SRC, STAT3, PIK3CA, and AKT1 are the five core targets of AOF in the treatment of DKD. Molecular docking simulation results showed that the five core compounds had good binding ability to the five core targets. Western blot validated the network pharmacological prediction results and showed that AOF and AOF-containing serum down-regulate the expression of TP53, and phosphorylation of SRC, STAT3, PIK3CA, and AKT.

Our study shows that AOF may delay the development of cellular senescence in DKD by down-regulating the levels of TP53, and phosphorylation of SRC, STAT3, PIK3CA, and AKT.

To evaluate the comparative effectiveness of sodium-glucose cotransporter-2 (SGLT-2) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, and dipeptidyl peptidase-4 (DPP-4) inhibitors in preventing hyperkalemia in people with type 2 diabetes in routine clinical practice.

Population based cohort study with active-comparator, new user design.

Claims data from Medicare and two large commercial insurance databases in the United States from April 2013 to April 2022.

1:1 propensity score matched adults with type 2 diabetes newly starting SGLT-2 inhibitors versus DPP-4 inhibitors (n=778 908), GLP-1 receptor agonists versus DPP-4 inhibitors (n=729 820), and SGLT-2 inhibitors versus GLP-1 receptor agonists (n=873 460).

Hyperkalemia diagnosis in the inpatient or outpatient setting. Secondary outcomes were hyperkalemia defined as serum potassium levels ≥5.5 mmol/L and hyperkalemia diagnosis in the inpatient or emergency department setting.

Starting SGLT-2 inhibitor treatment was associated with a lower rate of hyperkalemia than DPP-4 inhibitor treatment (hazard ratio 0.75, 95% confidence interval (CI) 0.73 to 0.78) and a slight reduction in rate compared with GLP-1 receptor agonists (0.92, 0.89 to 0.95). Use of GLP-1 receptor agonists was associated with a lower rate of hyperkalemia than DPP-4 inhibitors (0.79, 0.77 to 0.82). The three year absolute risk was 2.4% (95% CI 2.1% to 2.7%) lower for SGLT-2 inhibitors than DPP-4 inhibitors (4.6% v 7.0%), 1.8% (1.4% to 2.1%) lower for GLP-1 receptor agonists than DPP-4 inhibitors (5.7% v 7.5%), and 1.2% (0.9% to 1.5%) lower for SGLT-2 inhibitors than GLP-1 receptor agonists (4.7% v 6.0%). Findings were consistent for the secondary outcomes and among subgroups defined by age, sex, race, medical conditions, other drug use, and hemoglobin A1c levels on the relative scale. Benefits for SGLT-2 inhibitors and GLP-1 receptor agonists on the absolute scale were largest for those with heart failure, chronic kidney disease, or those using mineralocorticoid receptor antagonists. Compared with DPP-4 inhibitors, the lower rate of hyperkalemia was consistently observed across individual agents in the SGLT-2 inhibitor (canagliflozin, dapagliflozin, empagliflozin) and GLP-1 receptor agonist (dulaglutide, exenatide, liraglutide, semaglutide) classes.

In people with type 2 diabetes, SGLT-2 inhibitors and GLP-1 receptor agonists were associated with a lower risk of hyperkalemia than DPP-4 inhibitors in the overall population and across relevant subgroups. The consistency of associations among individual agents in the SGLT-2 inhibitor and GLP-1 receptor agonist classes suggests a class effect. These ancillary benefits of SGLT-2 inhibitors and GLP-1 receptor agonists further support their use in people with type 2 diabetes, especially in those at risk of hyperkalemia.

The evidence for sodium-glucose cotransporter 2 inhibitors (SGLT2i) in the treatment of type 2 diabetes or chronic heart failure was sufficient but lacking in acute coronary syndrome (ACS). Our aim was to investigate the effects of SGLT2i on cardiovascular outcomes in ACS patients. Studies of SGLT2i selection in ACS patients were searched and pooled. Outcomes included all-cause death, adverse cardiovascular events, cardiac remodeling as measured by the left ventricular end-diastolic dimension (LVEDD) and left ventricular end-systolic dimension (LVESD), cardiac function as assessed by the left ventricular ejection fraction (LVEF) and NT-proBNP, and glycemic control. Twenty-four studies with 12,413 patients were identified. Compared to the group without SGLT2i, SGLT2i showed benefits in reducing all-cause death (OR 0.72, 95% CI [0.61, 0.85]), major adverse cardiovascular events (MACE) (OR 0.44, 95% CI [0.30, 0.64]), cardiovascular death (OR 0.66, 95% CI [0.54, 0.81]), heart failure (OR 0.52, 95% CI [0.44, 0.62]), myocardial infarction (OR 0.68, 95% CI [0.56, 0.83]), angina pectoris (OR 0.37, 95% CI [0.17, 0.78]), and stroke (OR 0.48, 95% CI [0.24, 0.96]). Results favored SGLT2i for LVEDD (MD -2.03, 95% CI [-3.29, -0.77]), LVEF (MD 3.22, 95% CI [1.71, 4.72]), and NT-proBNP (MD -171.53, 95% CI [-260.98, -82.08]). Thus, SGLT2i treatment reduces the risk of all-cause death and MACE and improves cardiac remodeling and function in ACS patients.

Diabetes is associated with high risks of premature chronic kidney disease (CKD), cardiovascular diseases, cardiovascular death and impaired quality of life. People with diabetes are more likely to develop kidney impairment, and approximately one in three adults with diabetes have CKD. People with CKD and diabetes experience a substantially higher risk of cardiovascular outcomes. Sodium-glucose co-transporter protein 2 (SGLT2) inhibitors have shown potential effects in preventing kidney and cardiovascular outcomes in people with CKD and diabetes. However, new trials are emerging rapidly, and evidence synthesis is essential to summarising cumulative evidence.

This review aimed to assess the benefits and harms of SGLT2 inhibitors for people with CKD and diabetes.

We searched the Cochrane Kidney and Transplant Register of Studies up to 17 November 2023 using a search strategy designed by an Information Specialist. Studies in the Register are continually identified through regular searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov.

Randomised controlled studies were eligible if they evaluated SGLT2 inhibitors versus placebo, standard care or other glucose-lowering agents in people with CKD and diabetes. CKD includes all stages (from 1 to 5), including dialysis patients.

Two authors independently extracted data and assessed the study risk of bias. Treatment estimates were summarised using random effects meta-analysis and expressed as a risk ratio (RR) or mean difference (MD), with a corresponding 95% confidence interval (CI). Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. The primary review outcomes were all-cause death, 3-point and 4-point major adverse cardiovascular events (MACE), fatal or nonfatal myocardial infarction (MI), fatal or nonfatal stroke, and kidney failure.

Fifty-three studies randomising 65,241 people with CKD and diabetes were included. SGLT2 inhibitors with or without other background treatments were compared to placebo, standard care, sulfonylurea, dipeptidyl peptidase-4 (DPP-4) inhibitors, or insulin. In the majority of domains, the risks of bias in the included studies were low or unclear. No studies evaluated the treatment in children or in people treated with dialysis. No studies compared SGLT2 inhibitors with glucagon-like peptide-1 receptor agonists or tirzepatide. Compared to placebo, SGLT2 inhibitors decreased the risk of all-cause death (20 studies, 44,397 participants: RR 0.85, 95% CI 0.78 to 0.94; I2 = 0%; high certainty) and cardiovascular death (16 studies, 43,792 participants: RR 0.83, 95% CI 0.74 to 0.93; I2 = 29%; high certainty). Compared to placebo, SGLT2 inhibitors probably make little or no difference to the risk of fatal or nonfatal MI (2 studies, 13,726 participants: RR 0.95, 95% CI 0.80 to 1.14; I2 = 24%; moderate certainty), and fatal or nonfatal stroke (2 studies, 13,726 participants: RR 1.07, 95% CI 0.88 to 1.30; I2 = 0%; moderate certainty). Compared to placebo, SGLT2 inhibitors probably decrease 3-point MACE (7 studies, 38,320 participants: RR 0.89, 95% CI 0.81 to 0.98; I2 = 46%; moderate certainty), and 4-point MACE (4 studies, 23,539 participants: RR 0.82, 95% CI 0.70 to 0.96; I2 = 77%; moderate certainty), and decrease hospital admission due to heart failure (6 studies, 28,339 participants: RR 0.70, 95% CI 0.62 to 0.79; I2 = 17%; high certainty). Compared to placebo, SGLT2 inhibitors may decrease creatinine clearance (1 study, 132 participants: MD -2.63 mL/min, 95% CI -5.19 to -0.07; low certainty) and probably decrease the doubling of serum creatinine (2 studies, 12,647 participants: RR 0.70, 95% CI 0.56 to 0.89; I2 = 53%; moderate certainty). SGLT2 inhibitors decrease the risk of kidney failure (6 studies, 11,232 participants: RR 0.70, 95% CI 0.62 to 0.79; I2 = 0%; high certainty), and kidney composite outcomes (generally reported as kidney failure, kidney death with or without ≥ 40% decrease in estimated glomerular filtration rate (eGFR)) (7 studies, 36,380 participants: RR 0.68, 95% CI 0.59 to 0.78; I2 = 25%; high certainty) compared to placebo. Compared to placebo, SGLT2 inhibitors incur less hypoglycaemia (16 studies, 28,322 participants: RR 0.93, 95% CI 0.89 to 0.98; I2 = 0%; high certainty), and hypoglycaemia requiring third-party assistance (14 studies, 26,478 participants: RR 0.75, 95% CI 0.65 to 0.88; I2 = 0%; high certainty), and probably decrease the withdrawal from treatment due to adverse events (15 studies, 16,622 participants: RR 0.94, 95% CI 0.82 to 1.08; I2 = 16%; moderate certainty). The effects of SGLT2 inhibitors on eGFR, amputation and fracture were uncertain. No studies evaluated the effects of treatment on fatigue, life participation, or lactic acidosis. The effects of SGLT2 inhibitors compared to standard care alone, sulfonylurea, DPP-4 inhibitors, or insulin were uncertain.

SGLT2 inhibitors alone or added to standard care decrease all-cause death, cardiovascular death, and kidney failure and probably decrease major cardiovascular events while incurring less hypoglycaemia compared to placebo in people with CKD and diabetes.

This study was designed to assess the associations between emerging cardiometabolic indices-the atherogenic index of plasma (AIP), the stress hyperglycemia ratio (SHR), the triglyceride-glucose (TyG) index, and the homeostasis model assessment of insulin resistance (HOMA-IR)-and the incidence of diabetic kidney disease (DKD) in type 2 diabetes (T2D) patients.

We consecutively enrolled 4351 T2D patients. The AIP, SHR, TyG index, and HOMA-IR were calculated from baseline parameters. DKD was defined as a urine albumin/creatinine ratio > 30 mg/g or an eGFR < 60 mL/min per 1.73 m. All participants were categorized into tertiles based on the cardiometabolic indices. Multivariate logistic regression models, restricted cubic splines, and receiver operating characteristic (ROC) curves were used for analysis.

A total of 1371 (31.5%) patients were diagnosed with DKD. A restricted cubic spline showed a J-shaped association of the AIP and TyG index with DKD, a log-shaped association between HOMA-IR and DKD, and a U-shaped association between the SHR and DKD incidence. Multivariate logistic regression revealed that individuals in the highest tertile of the four cardiometabolic indices had a significantly greater risk of DKD than did those in the lowest tertile (AIP: OR = 1.08, 95% CI = 1.02-1.14, P = 0.005; SHR: OR = 1.42, 95% CI = 1.12-1.81, P = 0.004; TyG index: OR = 1.86, 95% CI = 1.42-2.45, P < 0.001; HOMA-IR: OR = 2.24, 95% CI = 1.52-3.30, P < 0.001). The receiver operating characteristic curves showed that the HOMA-IR score was better than other indices at predicting the risk of DKD, with an optimal cutoff of 3.532.

Elevated AIP, SHR, TyG index and HOMA-IR are associated with a greater risk of DKD in patients with T2D. Among these indices, the HOMA-IR score demonstrated the strongest association with and predictive value for DKD incidence.

Diabetic kidney disease (DKD) is the major complication of diabetes mellitus (DM) and one of the leading causes of end-stage renal disease. Early detection and treatment are contributing to delay the progression of DKD. Dietary management has potential benefits for DKD, especially the intake of polyunsaturated fatty acids (PUFAs). However, there is a lack of sufficient evidence, so we aimed to explore the association between PUFAs intake and DKD progression.

In the National Heath and Nutrition Examination Survey (NHANES) between 2011-2018, a cross-sectional study was conducted among adults with T2DM. DKD was diagnosed with urine albumin to creatinine ratio (ACR) ≥ 30 mg/g or estimated glomerular filtration rate (eGFR) ＜60 ml/min/1.73 m2. Using Survey package of R to arrange the collected PUFAs intake data in order from small to large and divide them into four equal parts, which were expressed as Q1, Q2, Q3 and Q4 respectively. To investigate the association between PUFAs intake and DKD, a weighted univariate logistic regression analysis was performed and the odds ratio (OR) and 95% confidence interval (CI) were calculated for the association with DKD and PUFAs quartiles.

The study involved 3287 participants with T2DM, including 2043 non-DKD and 1244 DKD patients. The results showed that the intake of PUFAs was a protective factor for DKD (p = 0.022), and with the increase of the PUFAs, renal function improved in DKD patients, the adjusted mean of eGFR and Scr changing from 57 (41, 86) in Q1 to 71 (55, 101) ml/min in Q4 (p 0.001), 103 (73, 131) in Q1 to 90 (68, 117) in Q4 (p = 0.031), respectively.

Our study indicated that intake of more PUFAs may contribute to delay DKD progression, while different n-6/n-3 ratios need to be explored to protect the kidney.

Sodium-glucose cotransporter 2 inhibitors (SGLT2Is) have beneficial effects on the renal function of chronic kidney disease (CKD) patients, although the types of patients suitable for this treatment remain unclear.

A retrospective observational study was conducted on CKD patients who were treated with SGLT2I in our department from 2020 to 2023. The estimated glomerular filtration rate (eGFR) just before treatment was defined as the baseline and the difference between pre-and post-treatment eGFR slopes were used to compare the improvement of renal function. Logistic regression analysis was used to evaluate the independent factors for its improvement.

A total of 128 patients were analyzed (mean age: 67.2 years; number of women: 28 [22%]). The mean eGFR was 42.1 mL/min/1.73 m2, and urine protein was 0.66 g/gCr. The eGFR slopes of patients with an eGFR <30 mL/min/1.73 m2 were improved significantly after treatment (-0.28 to -0.14 mL/min/1.73 m2/month, p < 0.001) but were worsened in patients with an eGFR ≥30 mL/min/1.73 m2. Logistic analysis for the improvement in eGFR slopes showed that women (odds ratio [OR], 5.63; 95% confidence interval [CI], 1.16-27.3; p = 0.03), use of mineralocorticoid receptor antagonists (OR, 11.79; 95% CI, 1.05-132.67; p = 0.012) and rapid decline of eGFR before treatment (OR, 12.8 per mL/min/1.73 m2/month decrease in eGFR; 95% CI, 3.32-49.40; p < 0.001) were significant independent variables.

SGLT2Is may have beneficial effects, especially for rapid decliners of eGFR, including advanced CKD.

Numerous studies demonstrated the risk factors for urological complications in patients with diabetes before sodium-glucose co-transporter 2 inhibitor (SGLT2i) became commercially available. This study aimed to comprehensively investigate urological characteristics in patients with type 2 diabetes (T2DM) after SGLT2i became commercially available.

We examined 63 outpatients with T2DM suspected of bacteriuria based on urinary sediment examinations. Urine cultures were performed, and lower urinary tract symptoms (LUTS) were assessed via questionnaires. Patients with bacteriuria were assessed using ultrasonography to measure post-void residual volume (PVR). Utilizing demographic and laboratory data, a random forest algorithm predicted LUTS, bacteriuria, and symptomatic bacteriuria (SB).

Thirty-two patients had LUTS and 31 had bacteriuria. High-density lipoprotein cholesterol level was crucial in predicting LUTS, while age was crucial in predicting bacteriuria. In predicting SB among patients with bacteriuria, creatinine level and estimated glomerular filtration rate were crucial. Our models had high predictive accuracy for LUTS (area under the curve [AUC] = 0.846), followed by bacteriuria (AUC = 0.770) and SB (AUC = 0.938) in receiver operating characteristic curve analysis. These predictors were previously reported as risk factors for urological complications. Although SGLT2i use was not an important predictor in our study, all SGLT2i users with bacteriuria had SB and exhibited higher PVR compared to non-SGLT2i users with bacteriuria.

This study's random forest model highlighted distinct essential predictors for each urological condition. The predictors were consistent before and after SGLT2i became commercially available.

The aim of this study is to evaluate the safety of this drug in diabetic patients with comorbidities of all systems.

In this review, the beneficial effects of this drug and its mechanism on the disorders of every system of humans in relation to diabetes have been studied, and finally, its adverse effects have also been discussed. The search for relevant information is carried out in the PubMed and Google Scholar databases by using the following terms: diabetes mellitus type 2, SGLT, SGLT2 inhibitors, (SGLT2 inhibitors) AND (Pleiotropic effects). All English-published articles from 2016 to 2023 have been used in this study. It should be noted that a small number of articles published before 2016 have been used in the introduction and general informations.

Its beneficial effects on improving cardiovascular disease risk factors and reducing adverse events caused by cardiovascular and renal diseases have proven in most large clinical studies that these effects are almost certain. It also has beneficial effects on other human systems such as the respiratory system, the gastrointestinal system, the circulatory system, and the nervous system; more of them are at the level of clinical and pre-clinical trials but have not been proven in large clinical trials or meta-analyses.

With the exception of a few adverse effects, this drug is considered a good choice and safe for all diabetic patients with comorbidities of all systems.

Chronic kidney disease (CKD) is a prevalent complication of Type II diabetes (T2D). The coexistence of CKD with T2D is comparable to cardiovascular disease (CVD) when the estimated glomerular filtration rate declines below 60 ml/min/1.73 m2. Screening and early detection of people with high risk for CKD would be beneficial in managing CKD progress and the associated complications such as CV complications. Renin-angiotensin-aldosterone system inhibitors (RAASi) have demonstrated beneficial effects in delaying CKD progression, but they carry the risk of hyperkalemia. Nonsteroidal mineralocorticoid antagonists (nsMRA), such as finerenone, exhibit considerable efficacy in their anti-inflammatory, antifibrotic, and renal protective effects with demonstrable reductions in CV complications. In addition, nsMRAs do not cause significant changes in serum potassium levels compared to traditional steroidal MRA. Ongoing research explores the capacity of the sodium-glucose transport protein 2 inhibitors (SGLT-2i), combined with nsMRA, to produce synergistic renal protective effects and reduce the risk of hyperkalemia. Also, a dedicated renal outcomes study (FLOW study) involving a once-weekly injectable Glucagon-like peptide-1 receptor agonist, semaglutide, was halted early by the data monitoring committee due to having achieved the predefined efficacy endpoint and considerations related to renal disease. In CKD patients with T2D on nsMRA, hyperkalemia management requires a comprehensive approach involving lifestyle adjustments, dietary modifications, regular serum potassium level monitoring, and potassium binders, if necessary. Withholding or down-titration of nsMRAs with close monitoring of serum potassium levels may be required in patients with concerning potassium levels. In light of the current state of knowledge, this review article explores the perspectives and approaches that HCPs may consider when monitoring and managing hyperkalemia in CKD patients with T2D.

Hyperkalemia is a common adverse event in patients with chronic kidney disease (CKD) and type 2 diabetes and limits the use of guideline-recommended therapies such as renin-angiotensin system inhibitors. Here, we evaluated the comparative effects of sodium-glucose cotransporter-2 inhibitors (SGLT-2i), glucagon-like peptide-1 receptor agonists (GLP-1RA) and dipeptidyl peptidase-4 inhibitors (DPP-4i) on the risk of hyperkalemia. We conducted a population-based active-comparator, new-user cohort study using claims data from Medicare and two large United States commercial insurance databases (April 2013-April 2022). People with CKD stages 3-4 and type 2 diabetes who newly initiated SGLT-2i vs. DPP-4i (141671 patients), GLP-1RA vs. DPP-4i (159545 patients) and SGLT-2i vs. GLP-1RA (93033 patients) were included. The primary outcome was hyperkalemia diagnosed in inpatient or outpatient settings. Secondary outcomes included hyperkalemia diagnosed in inpatient or emergency department setting, and serum potassium levels of 5.5 mmol/L or more. Pooled hazard ratios and rate differences were estimated after propensity score matching to adjust for over 140 potential confounders. Initiation of SGLT-2i was associated with a lower risk of hyperkalemia compared with DPP-4i (hazard ratio 0.74; 95% confidence interval 0.68-0.80) and contrasted to GLP-1RA (0.92; 0.86-0.99). Compared with DPP-4i, GLP-1RA were also associated with a lower risk of hyperkalemia (0.80; 0.75-0.86). Corresponding absolute rate differences/1000 person-years were -24.8 (95% confidence interval -31.8 to -17.7), -5.0 (-10.9 to 0.8), and -17.7 (-23.4 to -12.1), respectively. Similar findings were observed for the secondary outcomes, among subgroups, and across single agents within the SGLT-2i and GLP-1RA classes. Thus, SGLT-2i and GLP-1RA are associated with a lower risk of hyperkalemia than DPP-4i in patients with CKD and type 2 diabetes, further supporting the use of these drugs in this population.

Contrast-induced nephropathy has become increasingly prevalent as the age and prevalence of comorbidities in the general population have increased. Most cases of contrast-induced nephropathy are reversible; however, some may progress to acute kidney disease, and subsequently, to chronic kidney disease. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are known for their renoprotective effects. However, whether the use of these inhibitors affects the risk of contrast-induced kidney injury remains unclear.

Data were collected from the Taipei Medical University Clinical Research Database. We included patients with diabetes who had contrast exposure between 2016 and 2020 because of computed tomography or coronary angiography. The primary outcome was the risk of a major adverse kidney event (MAKE), which encompassed acute kidney disease, chronic kidney disease progression, and the need for renal replacement therapy. Overlap weighting was performed to reduce the effects of potential confounders.

This study included 12 421 patients, who were divided into two groups: SGLT2i users (n = 920) and nonusers (n = 11 501). The follow-up period after contrast exposure was 6 months. The risk of a MAKE was lower in SGLT2i users than in nonusers (incidence, 36.9 vs. 49.9 per 1000 person-months, respectively; P = .0011). Furthermore, the incidence of acute kidney disease or chronic kidney disease progression was significantly lower in the SGLT2i users than in nonusers. However, no significant between-group difference was noted in the incidence of other MAKEs.

SGLT2i may be safely used in diabetic patients needing contrast exposure. The risk of a MAKE may be lower in SGLT2i users than in nonusers.

Recent studies demonstrate that sodium-glucose cotransporter 2 inhibitors (SGLT2i) and dipeptidyl peptidase-4 inhibitors (DPP4i), two classes of antidiabetic drugs, are cardioprotective. However, the mechanisms of these benefits and their comparative efficacy remain unclear. We aimed to compare the effects of these antidiabetic agents on cardiac function, perfusion, and microvascular density using a swine model of chronic myocardial ischemia.

Chronic myocardial ischemia was induced in Yorkshire swine by ameroid constrictor placement to the left circumflex artery. Two weeks later, pigs were administered vehicle ("CON", 8 pigs), 300 mg SGLT2i canagliflozin, ("CANA", 8 pigs), or 100 mg DPP4i sitagliptin ("SIT", 5 pigs) daily. Five weeks later, pigs were euthanized. Cardiac function, perfusion, collateralization, and protein expression were determined by pressure-volume catheter, microsphere analysis, immunofluorescence, and immunoblotting, respectively.

Compared with SIT, CANA was associated with improved stroke volume and cardiac output, with a trend towards reduced left ventricular stiffness. Both CANA and SIT trended towards improved perfusion compared to CON, but there were no differences between the two treatment groups. SIT was associated with improved capillary density with a trend towards improved arteriolar density compared to CANA. Both CANA and SIT were associated with increased expression of vascular endothelial cadherin compared to CON, without differences in treatment groups. SIT pigs had decreased 5' adenosine monophosphate-activated protein kinase activation compared to CON and CANA. There was a trend towards increased endothelial nitric oxide synthase activation in the SIT group compared to CON. There were no differences in activation of extracellular signal-regulated kinase 1/2 across groups.

In the setting of chronic myocardial ischemia, canagliflozin is associated with improved cardiac function compared to sitagliptin, with similar effects on perfusion despite differences in microvascular collateralization.

Garlic (Allium sativum L.) is a popular spice that is widely used for food and medicinal purposes and has shown potential effects on diabetic kidney disease (DKD). Nevertheless, systematic preclinical studies are still lacking. In this meta-analysis and systematic review, we evaluated the role and potential mechanisms of action of garlic and its derived components in animal models of DKD. We searched eight databases for relevant studies from the establishment of the databases to December 2022 and updated in April 2023 before the completion of this review. A total of 24 trials were included in the meta-analysis. It provided preliminary evidence that supplementing with garlic could improve the indicators of renal function (BUN, Scr, 24 h urine volume, proteinuria, and KI) and metabolic disorders (BG, insulin, and body weight). Meanwhile, the beneficial effects of garlic and its components in DKD could be related to alleviating oxidative stress, suppressing inflammatory reactions, delaying renal fibrosis, and improving glucose metabolism. Furthermore, time-dose interval analysis exhibited relatively greater effectiveness when garlic products were supplied at doses of 500 mg kg-1 with interventions lasting 8-10 weeks, and garlic components were administered at doses of 45-150 mg kg-1 with interventions lasting 4-10 weeks. This meta-analysis and systematic review highlights for the first time the therapeutic potential of garlic supplementation in animal models of DKD and offers a more thorough evaluation of its effects and mechanisms to establish an evidence-based basis for designing future clinical trials.
