Cardiovasc Diabetol 2024; 23:323. [PMID: 39217364 PMCID: PMC11366144 DOI: 10.1186/s12933-024-02413-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2024] [Accepted: 08/19/2024] [Indexed: 09/04/2024] Open
Abstract
BACKGROUND Diabetes mellitus (DM), prediabetes, and insulin resistance are highly prevalent in patients with ischemic stroke (IS). DM is associated with higher risk for poor outcomes after IS. OBJECTIVE Investigate the risk of recurrent vascular events and mortality associated with impaired glucose metabolism compared to normoglycemia in patients with IS and transient ischemic attack (TIA). METHODS Systematic literature search was performed in PubMed, Embase, Cochrane Library on 21st March 2024 and via citation searching. Studies that comprised IS or TIA patients and exposures of impaired glucose metabolism were eligible. Study Quality Assessment Tool was used for risk of bias assessment. Covariate adjusted outcomes were pooled using random-effects meta-analysis. MAIN OUTCOMES Recurrent stroke, cardiac events, cardiovascular and all-cause mortality and composite of vascular outcomes. RESULTS Of 10,974 identified studies 159 were eligible. 67% had low risk of bias. DM was associated with an increased risk for composite events (pooled HR (pHR) including 445,808 patients: 1.58, 95% CI 1.34-1.85, I2 = 88%), recurrent stroke (pHR including 1.161.527 patients: 1.42 (1.29-1.56, I2 = 92%), cardiac events (pHR including 443,863 patients: 1.55, 1.50-1.61, I2 = 0%), and all-cause mortality (pHR including 1.031.472 patients: 1.56, 1.34-1.82, I2 = 99%). Prediabetes was associated with an increased risk for composite events (pHR including 8,262 patients: 1.50, 1.15-1.96, I2 = 0%) and recurrent stroke (pHR including 10,429 patients: 1.50, 1.18-1.91, I2 = 0), however, not with mortality (pHR including 9,378 patients, 1.82, 0.73-4.57, I2 = 78%). Insulin resistance was associated with recurrent stroke (pHR including 21,363 patients: 1.56, 1.19-2.05, I2 = 55%), but not with mortality (pHR including 21,363 patients: 1.31, 0.66-2.59, I2 = 85%). DISCUSSION DM is associated with a 56% increased relative risk of death after IS and TIA. Risk estimates regarding recurrent events are similarly high between prediabetes and DM, indicating high cardiovascular risk burden already in precursor stages of DM. There was a high heterogeneity across most outcomes.

Abstract
Ischemic stroke is the primary reason for human disability and death, but the available treatment options are limited. Hence, it is imperative to explore novel and efficient therapies. In recent years, pyroptosis (a pro-inflammatory cell death characterized by inflammation) has emerged as an important pathological mechanism in ischemic stroke that can cause cell death through plasma membrane rupture and release of inflammatory cytokines. Pyroptosis is closely associated with inflammation, which exacerbates the inflammatory response in ischemic stroke. The level of inflammasomes, GSDMD, Caspases, and inflammatory factors is increased after ischemic stroke, exacerbating brain injury by mediating pyroptosis. Hence, inhibition of pyroptosis can be a therapeutic strategy for ischemic stroke. In this review, we have summarized the relationship between pyroptosis and ischemic stroke, as well as a series of treatments to attenuate pyroptosis, intending to provide insights for new therapeutic targets on ischemic stroke.

Heliyon 2023; 9:e16171. [PMID: 37287614 PMCID: PMC10232936 DOI: 10.1016/j.heliyon.2023.e16171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 04/22/2023] [Accepted: 05/08/2023] [Indexed: 06/09/2023] Open
Abstract
Objective Famotidine has been proposed as a promising candidate for the treatment of coronavirus disease 2019 (COVID-19). However, there is limited research on the association of famotidine with the poor prognosis of COVID-19. Methods The Korean nationwide cohort included 6,556 patients who tested positive on RT-PCR for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The poor COVID-19-related outcomes were defined on the basis of having encountered the composite outcome of high oxygen therapy, intensive care unit admission, administration of mechanical ventilation, or death. In addition, we performed exposure-driven propensity score matching for no H2-blocker use versus current famotidine use, and other H2-blocker use versus current famotidine use. Results 4,785 (73.0%) patients did not use a H2-blocker, 393 (6.0%) patients were currently used famotidine, and 1,292 (19.7%) patients currently used H2-blocker other than famotidine. In multivariable analysis after matching (no H2-blocker use versus current famotidine use), there was no significant association between current famotidine use and composite outcomes (adjusted odd ratios [aOR]: 1.30, 95% confidence interval [CI]: 0.55-3.06). On the other hand, another matched cohort (other H2-blocker use versus current famotidine use), demonstrated a positive association between current famotidine use and composite outcomes (aOR: 3.56, 95% CI: 1.03-12.28). Conclusions Our study results did not support the potential of famotidine as a therapeutic agent for COVID-19. A rather unexpected result could be observed in the comparisons between current famotidine use and other H2-blocker use; it was observed that current famotidine use increased the risk of poor COVID-19 related outcomes. Further studies are needed to clearly prove the causal relationship with several H2-blockers, including famotidine.

Cardiovasc Diabetol 2023; 22:106. [PMID: 37147722 PMCID: PMC10163714 DOI: 10.1186/s12933-023-01841-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 04/25/2023] [Indexed: 05/07/2023] Open
Abstract
INTRODUCTION Ischemic stroke patients with diabetes are at high risk for recurrent stroke and cardiovascular complications. Pioglitazone, a type of thiazolidinedione, has been shown to reduce cardiovascular complications in patients with ischemic stroke and type 2 diabetes (T2D) or insulin resistance. Lobeglitazone is a novel thiazolidinedione agent that improves insulin resistance and has similar glycemic efficacy to pioglitazone. Using population-based health claims data, we evaluated whether lobeglitazone has secondary cardiovascular preventive effects in patients with ischemic stroke and T2D. METHODS This study has a nested case-control design. From nationwide health claims data in Korea, we identified patients with T2D admitted for acute ischemic stroke in 2014-2018. Cases were defined who suffered the primary outcome (a composite of recurrent stroke, myocardial infarction, and all-cause death) before December 2020. Three controls were selected by incidence density sampling for each case from those who were at risk at the time of their case occurrence with exact matching on sex, age, the presence of comorbidities, and medications. As a safety outcome, we also evaluated the risk of heart failure (HF) according to the use of lobeglitazone. RESULTS From the cohort of 70,897 T2D patients with acute ischemic stroke, 20,869 cases and 62,607 controls were selected. In the multivariable conditional logistic regression, treatment with lobeglitazone (adjusted OR 0.74; 95% CI 0.61-0.90; p = 0.002) and pioglitazone (adjusted OR 0.71; 95% CI 0.64-0.78; p < 0.001) were significantly associated with a lower risk for the primary outcome. In a safety outcome analysis for HF, treatment with lobeglitazone did not increase the risk of HF (adjusted OR 0.90; 95% CI 0.66-1.22; p = 0.492). CONCLUSIONS In T2D patients with ischemic stroke, lobeglitazone reduced the risk of cardiovascular complications similar to that of pioglitazone without an increased risk of HF. There is a need for further studies on the cardioprotective role of lobeglitazone, a novel thiazolidinedione.

Abstract
Alzheimer's disease (AD) is the main cause of dementia in older age. The prevalence of AD is growing worldwide, causing a tremendous burden to societies and families. Due to the complexity of its pathogenesis, the current treatment of AD is not satisfactory, and drugs acting on a single target may not prevent AD progression. This review summarizes the multi-target pharmacological effects of thiazolidinediones (TZDs) on AD. TZDs act as peroxisome proliferator-activated receptor gamma (PPARγ) agonists and long-chain acyl-CoA synthetase family member 4 (ACSL4) inhibitors. TZDs ameliorated neuroinflammation and ferroptosis in preclinical models of AD. Here, we discussed recent findings from clinical trials of pioglitazone in the treatment of AD, ischemic stroke, and atherosclerosis. We also dissected the major limitations in the clinical application of pioglitazone and explained the potential benefit of pioglitazone in AD. We recommend the use of pioglitazone to prevent cognitive decline and lower AD risk in a specific group of patients.

Abstract
Background Chronic surgical anaesthesia and uncontrolled hyperglycemia are bidirectional risk factors for the development of psychiatric, cerebrovascular, and cardiovascular diseases. Objective The current study was designed to elucidate the neuroprotective effects of anti-diabetic agents in pre and post-surgical anaesthesia exposure on diabetic ischemic rats. Methods The diabetes type-2 was induced and rats having more than 250 gm/dl blood glucose levels were considered for study. Administration of anaesthetic agents (ketamine 100 mg/kg IP, xylazine 10 mg/kg IP) were done pre and post MCAo surgery for 7 days. The treatment with anti-diabetic agents (voglibose, saxagliptin, repaglinide, dapagliflozin) was carried out after 7 days of Post MCAo surgery for one week. After treatment, assessment of neurobehavioral function was carried out using Morris Water Maze. After that, brains were excised and bloods were collected from all groups subjected for assessment of neuromodulator levels, oxidative stress parameters, serum biochemical biomarkers. Results The treatment with voglibose and saxagliptin not only improved neuromodulator levels statistically significant (p < 0.001) and cognitive profile but also significantly improved (p < 0.01) overall stroke serum biomarkers (Serum Glucose, GGT, CRP, CK-MB, LDH). Conclusion The results of the present study, suggested that chronic exposure of anaesthesia worsens the cognition and increases risk of stroke biomarkers in diabetic conditions. We can conclude that voglibose, saxagliptin, and dapagliflozin can significantly improve the postoperative mortality, morbidity, and cognitive dysfunction caused by post-surgical stress and chronic anaesthesia-induced cognitive dysfunction.

Abstract
INTRODUCTION We investigated cardiovascular risk due to proton pump inhibitor (PPI) treatment using a self-controlled case series (SCCS) study design, a type of case-only design and an approach to overcome between-person confounding in which individuals act as their own control. METHODS We conducted an SCCS study using the National Health Insurance Service-Health Screening cohort in Korea (2002-2015). The cohort included 303,404 adult participants without prior cardiovascular events, who were followed up until December 2015. The primary outcome was a composite of stroke or myocardial infarction. The SCCS method estimated the age-adjusted incidence rate ratio between periods with and without exposure to PPI among patients with primary outcomes. As sensitivity analysis, conventional multivariable Cox proportional regression analyses were performed, which treated the exposure to PPI and H2 blocker during follow-up as time-dependent variables. RESULTS In the SCCS design, 10,952 (3.6%) patients with primary outcomes were included. There was no association between PPI exposure and primary outcome (incidence rate ratio 0.98, 95% confidence interval [CI] 0.89-1.09). In the time-dependent Cox regression analyses, both PPI (adjusted hazard ratio 1.36, 95% CI 1.24-1.49) and H2 blocker (adjusted hazard ratio 1.46, 95% CI 1.38-1.55) were associated with an increased risk of the primary outcome. DISCUSSION Negative findings in the SCCS design suggest that association between increased cardiovascular risk and PPI, frequently reported in prior observational studies, is likely due to residual confounding related to conditions with PPI treatment, rather than a true relationship.

Abstract
Abstract
Background
Research on the association of non-alcoholic fatty liver disease (NAFLD) with prognosis in COVID-19 has been limited. We investigated the association between the fatty liver index (FLI), a non-invasive and simple marker of NAFLD, and the severe complications of COVID-19 patients in South Korea.
Methods
We included 3122 COVID-19-positive patients from the nationwide COVID-19 cohort dataset in South Korea between January and June 2020. The FLI was calculated using triglyceride, body mass index, glutamyl transpeptidase, and waist circumference, which were obtained from the national health screening program data. Severe complications related to COVID-19 were defined as the composite of mechanical ventilation, intensive care unit treatment, high-oxygen flow therapy, and death within 2 months after a COVID-19 infection. We performed a multivariate logistic regression analysis for the development of severe complications in COVID-19 patients.
Results
The mean ± standard deviation of FLI were 25.01 ± 22.64. Severe complications from COVID-19 occurred in 223 (7.14%) patients, including mechanical ventilation in 82 (2.63%) patients, ICU admission in 126 (4.04%), high-flow oxygen therapy in 75 (2.40%), and death in 94 (3.01%) patients, respectively. The multivariate analysis indicated that the highest tertile (T3) of FLI was positively associated with severe complications from COVID-19 (adjusted odds ratio (OR): 1.77, 95% confidence interval (CI) (1.11–2.82), P = 0.017) compared with the lowest tertile (T1).
Conclusions
Our study demonstrated that FLI, which represents NAFLD, was positively associated with an increased risk of severe complications from COVID-19. FLI might be used as a prognostic marker for the severity of COVID-19.

Abstract
BACKGROUND The exact pathophysiological mechanism of transient global amnesia (TGA) is unknown. It is debatable whether TGA is a risk factor for stroke. Therefore, here we investigated the possibility of TGA as a risk factor for stroke in a real-world setting using large-scale nationwide health claims data. METHODS We used health claims data from the Korean National Health Insurance Service (NHIS). Patients diagnosed with TGA between 2007 and 2013 were selected. We initially extracted patients without TGA who were preferentially matched for age and sex with the patients with TGA at a ratio of 10:1 from the whole dataset. Further, we performed 1:2 propensity score matching analysis to balance the baseline characteristics between the two groups. In the propensity score-matched dataset, we performed multivariable Cox regression analysis to investigate the association between TGA and stroke type, including ischaemic, haemorrhagic and all stroke types. RESULTS Patients with TGA (n=14 673) were selected from the NHIS database. After extracting from the whole database (n=140 486) and propensity score matching their data at a 1:2 ratio, a total of 10 448 and 20 442 patients were finally assigned to the TGA and control groups, respectively. The multivariable Cox regression analysis demonstrated that the TGA group had a higher risk of ischaemic stroke and all types of stroke (adjusted HR=1.194; 95% CI: 1.043 to 1.368; and HR=1.197; 95% CI: 1.056 to 1.357, respectively). CONCLUSIONS Analysis of the nationwide claims database showed that TGA could be an important risk factor for stroke, especially for ischaemic stroke.

Abstract
Objective To understand the incidence of stroke in patients with type 2 diabetes mellitus (T2DM) and/or hypertension (HTN), and provide a basis for the prevention of stroke in these patients. Methods A prospective cohort study was performed for adults with T2DM and/or HTN. The follow-up period was 1 year. The incidence and recurrence rate of stroke was calculated and a multivariate Cox proportional hazard was used to analyze influencing factors of stroke occurrence and recurrence in the follow-up of patients with T2DM and/or HTN. Results Of the 1,650 patients with T2DM and/or HTN, 1,213 patients had no history of stroke. After 1 year of follow-up, 147 new stroke cases occurred, and the incidence rate of stroke was 12.1%. Among the patients who had stroke history (413), there were 116 cases of stroke with a recurrence rate of 26.5%. Seven risk factors were independently associated with stroke occurrence among patients without stroke history, included smoking, abnormal total cholesterol abnormal low-density lipoprotein patients with comorbid T2DM with HTN, physical inactivity, carotid artery stenosis (CAS), and higher scores of National Institutes of Health Stroke Scale (NIHSS). Higher scores of NHISS and CAS were independent risk factors for the recurrence of stroke among patients with stroke history. Conclusions Patients with T2DM and/or HTN have a higher rate of new stroke and recurrence after 1-year follow-up. Actively identifying the controllable risk factors, such as smoking and physical inactivity, will help reduce the risk of stroke and recurrence in patients with T2DM and HTN.

Abstract
BACKGROUND Periodontitis is a common chronic inflammatory disease and one of oral complications in diabetes. Diabetes-related microvascular complications and periodontitis are also closely related to systemic inflammation. We hypothesized that periodontitis and oral hygiene markers might increase the risk of microvascular complications in diabetes mellitus. METHODS We enrolled 11,353 diabetes participants without prior microvascular complications who received complete oral health checkups in the National Health Insurance Service-National Health Screening Cohort in 2003-2004. The primary outcome was the first development of diabetes-related microvascular complications, including nephropathy, neuropathy, and retinopathy. RESULTS The age of all participants was 55.27 ± 9.46 years, and 7833 (68.99%) participants were male. Periodontitis was noted in 8.37%. During the 7.03 ± 4.30 year of the mean follow-up period, 7227 patients experienced diabetes-related microvascular complications (2645 with nephropathy, 2513 with neuropathy, 2069 with retinopathy). Multivariable Cox regression analyses revealed that periodontitis was an independent risk factor for diabetes-related microvascular complications (adjusted hazard ratio (HR):1.13; 95% confidence interval (CI):1.04-1.23; p = 0.004). In the secondary analysis for individual microvascular complications, periodontitis was an independent risk factor for retinopathy (adjusted HR: 1.21; 95% CI: 1.04-1.40; p = 0.013). CONCLUSIONS The presence of periodontitis was associated with an increased risk of microvascular complications in diabetes patients.

Abstract
Nearly 18 million people died from cardiovascular diseases in 2019, of these 85% were due to heart attack and stroke. The available therapies although efficacious, have narrow therapeutic window and long list of contraindications. Therefore, there is still an urgent need to find novel molecular targets that could protect the brain and heart against ischemia without evoking major side effects. Nuclear receptors are one of the promising targets for anti-ischemic drugs. Modulation of estrogen receptors (ERs) and peroxisome proliferator-activated receptors (PPARs) by their ligands is known to exert neuro-, and cardioprotective effects through anti-apoptotic, anti-inflammatory or anti-oxidant action. Recently, it has been shown that the expression of aryl hydrocarbon receptor (AhR) is strongly increased after brain or heart ischemia and evokes an activation of apoptosis or inflammation in injury site. We hypothesize that activation of ERs and PPARs and inhibition of AhR signaling pathways could be a promising strategy to protect the heart and the brain against ischemia. In this Review, we will discuss currently available knowledge on the mechanisms of action of ERs, PPARs and AhR in experimental models of stroke and myocardial infarction and future perspectives to use them as novel targets in cardiovascular diseases.

Abstract
Infection is associated with occurrence and worsening of heart failure (HF). However, studies on the association of susceptibility and severe complications of coronavirus disease 2019 (COVID-19) with HF history are limited. From the Korean nationwide COVID-19 data set, 212,678 participants with at least one severe acute respiratory syndrome coronavirus 2 real-time reverse transcription polymerase chain reaction (RT-PCR) test were included between January 1 and June 4, 2020. To investigate the association of HF with susceptibility and severe complications of COVID-19, 1:4 ratio propensity score matching (PSM) and logistic regression analysis were performed. The primary outcome was a composite outcome of mechanical ventilation, intensive care unit (ICU) admission, and death. After PSM, COVID-19 PCR positivity did not show a significant difference according to HF history in multivariable analysis (odds ratio [OR]: 0.91, 95% confidence interval (CI) (0.79-1.04), p = 0.146). Of 7630 individuals with confirmed COVID-19 infection, 310 (4.1%) had HF history. The overall primary outcome occurred in 426 (5.6%) individuals, including 159 (2.1%) cases of mechanical ventilation, 254 (3.3%) cases of ICU admission, and 215 (2.8%) cases of death. In multivariate logistic analysis, presence of HF history was associated independently with primary outcome (OR: 1.99, 95% CI: 1.42-2.79, p < 0.001), particularly mortality (OR: 2.02, 95% CI: 1.36-3.00, p < 0.001). Our study demonstrated that HF history is associated poor prognosis, particularly mortality, in COVID-19. Patients with HF can have severe complication if infected with COVID-19; therefore, careful management are necessary.

Abstract
BACKGROUND Stroke remains a leading cause of death and disability throughout the world. It is well established that Diabetes Mellitus (DM) is a risk factor for stroke, while other risk factors include dyslipidaemia and hypertension. Given that the global prevalence of diabetes steadily increases, the need for adequate glycaemic control and prevention of DM-related cardiovascular events remains a challenge for the medical community. Therefore, a re-examination of the latest data related to this issue is of particular importance. OBJECTIVE This review aims to summarise the latest data on the relationship between DM and stroke, including epidemiology, risk factors, pathogenesis, prevention and biomarkers. METHODS For this purpose, comprehensive research was performed on the platforms PubMed, Google Scholar and EMBASE with a combination of the following keywords: diabetes mellitus, stroke, macrovascular complications, diabetic stroke, cardiovascular disease. CONCLUSIONS Much progress has been made in stroke in people with DM in terms of prevention and early diagnosis. In the field of prevention, the adaptation of the daily habits and the regulation of co-morbidity of individuals play a particularly important role. Simultaneously, the most significant revolution has been brought by the relatively new treatment options that offer protection to the cardiovascular system. Moreover, many prognostic and diagnostic biomarkers have been identified, paving the way for early and accurate diagnoses. However, to date, there are crucial points that remain controversial and need further clarification.

Abstract
BACKGROUND Cardiovascular risk increases following herpes zoster. We investigated whether treatment with antiviral agents, steroids, and common cardiovascular medications was associated with the risk of postherpetic cardiovascular events. METHODS This was a nationwide population-based, retrospective, cohort study using the National Health Insurance Service health claims data in Korea. We included patients with a first-ever diagnosis of herpes zoster in 2003-2014 and no prior cardiovascular event. The primary outcome was the occurrence of composites of myocardial infarction (International Statistical Classification of Diseases, Tenth Revision, code I21) and stroke (codes I60-I63) since the herpes zoster. We analyzed the exposure (intravenous or oral administration) to antiviral agents, steroids, antithrombotics, and statins within ±7 days from the index date of herpes zoster diagnosis. Follow-up was performed until occurrence of the primary outcome, death, or 31 December 2015, whichever came first. RESULTS Of 84 993 patients with herpes zoster, the proportions of patients who received the treatment with antiviral agents, steroids, antithrombotics, and statins were 90.5%, 48.0%, 9.1%, and 7.9%, respectively. During the mean (standard deviation) follow-up period of 5.4 (3.1) years, 1523 patients experienced the primary outcome. Multivariate Cox regression analysis demonstrated that treatment with antiviral agents (adjusted hazard ratio, 0.82; 95% confidence interval, .71-.95) and statins (0.71; .59-.85) were significantly associated with the lower risk of primary outcome. Use of antithrombotics and steroids were not associated with the risk. CONCLUSIONS After herpes zoster, treatment with antiviral agents was significantly associated with lower risk of cardiovascular events. We need more information on the cardiovascular protective role of herpes zoster treatments.

Pioglitazone use associated with reduced risk of the first attack of ischemic stroke in patients with newly onset type 2 diabetes: a nationwide nested case-control study. Cardiovasc Diabetol 2021; 20:152. [PMID: 34315501 PMCID: PMC8314540 DOI: 10.1186/s12933-021-01339-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Accepted: 07/08/2021] [Indexed: 11/12/2022] Open
Abstract
Background Pioglitazone use is known to be associated with a reduced risk of recurrent stroke in patients with diabetes mellitus (DM) who have a history of stroke. However, it is unclear whether this benefit extends to patients without a history of stroke. We aimed to evaluate the association between pioglitazone use and development of first attack of ischemic stroke in patients with newly diagnosed type 2 DM. Methods Using longitudinal nationwide data from the 2002–2017 Korean National Health Insurance Service DM cohort, we analyzed the association between pioglitazone use and incidence of primary ischemic stroke using a nested case–control study. Among 128,171 patients with newly onset type 2 DM who were stroke-free at the time of DM diagnosis, 4796 cases of ischemic stroke were identified and matched to 23,980 controls based on age, sex, and the onset and duration of DM. The mean (standard deviation) follow-up time was 6.08 (3.34) years for the cases and controls. Odds ratios (ORs) and 95% confidence intervals (CIs) for the association between ischemic stroke and pioglitazone use were analyzed by multivariable conditional logistic regression analyses adjusted for comorbidities, cardiometabolic risk profile, and other oral antidiabetic medications. Results Pioglitazone use was associated with a reduced risk of first attack of ischemic stroke (adjusted OR [AOR] 0.69, 95% CI 0.60–0.80) when compared with non-use. Notably, pioglitazone use was found to have a dose-dependent association with reduced rate of ischemic stroke emergence (first cumulative defined daily dose [cDDD] quartile AOR 0.99, 95% CI 0.74–1.32; second quartile, AOR 0.77, 95% CI 0.56–1.06; third quartile, AOR 0.51, 95% Cl 0.36–0.71; highest quartile, AOR 0.48, 95% CI 0.33–0.69). More pronounced risk reduction was found in patients who used pioglitazone for more than 2 years. A further stratified analysis revealed that pioglitazone use had greater protective effects in patients with risk factors for stroke, such as high blood pressure, obesity, and current smoking. Conclusions Pioglitazone use may have a preventive effect on primary ischemic stroke in patients with type 2 DM, particularly in those at high risk of stroke.

Abstract
Glucagon-like peptide-1 (GLP-1) receptor (GLP-1R) agonist exendin-4 (Ex-4), a drug that has been used in the clinical treatment of type 2 diabetes mellitus, also confers a neuroprotective effect against stroke. Although GLP-1 analogs were reported to induce sustained insulin secretion and glucose tolerance improved after cessation of treatment, no study has revealed whether Ex-4 exerts sustained neuroprotection against stroke and the underlying mechanism after treatment cessation. In this study, mice were pretreated with Ex-4 for 7 days, and middle cerebral artery occlusion (MCAO) was performed on different days after cessation of Ex-4 treatment. Ex-4 ameliorated neurological dysfunction and reduced the infarct volume induced by MCAO. These protective effects lasted for 6 days after the cessation of Ex-4 treatment and were associated with sustained upregulation of PI3K, AKT, mTOR, and HIF-1α levels, as well as HIF-1α downstream genes. Knockdown of GLP-1R or HIF-1α in the brain by short hairpin RNA abolished Ex-4 treatment-mediated neuroprotection. In normal mice, Ex-4 treatment led to instant upregulation of p-PI3K, p-AKT, p-mTOR, and HIF-1α expression levels, which quickly returned to normal after cessation of Ex-4 treatment, while the expression levels of insulin growth factor-1 receptor (IGF-1R) remained high for 6 days after Ex-4 cessation. Additionally, Ex-4 did not directly induce IGF-1 production, which was only induced by MCAO. Ex-4 induces extended cerebral ischemic tolerance. This neuroprotective effect is associated with activation of GLP-1R and upregulation of IGF-1R in the brain, and the latter then activates the PI3K/AKT/mTOR/HIF-1 signaling pathway via binding to IGF-1 secreted from the ischemic brain.

Abstract
The global incidence and prevalence of type 2 diabetes have been escalating in recent decades. The total diabetic population is expected to increase from 415 million in 2015 to 642 million by 2040. Patients with type 2 diabetes have an increased risk of atherosclerotic cardiovascular disease (ASCVD). About two-thirds of patients with type 2 diabetes died of ASCVD. The association between hyperglycemia and elevated cardiovascular (CV) risk has been demonstrated in multiple cohort studies. However, clinical trials of intensive glucose reduction by conventional antidiabetic agents did not significantly reduce macrovascular outcomes.In December 2008, U.S. Food and Drug Administration issued a mandate that every new antidiabetic agent requires rigorous assessments of its CV safety. Thereafter, more than 200,000 patients have been enrolled in a number of randomized controlled trials (RCTs). These trials were initially designed to prove noninferiority. It turned out that some of these trials demonstrated superiority of some new antidiabetic agents versus placebo in reducing CV endpoints, including macrovascular events, renal events, and heart failure. These results are important in clinical practice and also provide an opportunity for academic society to formulate treatment guidelines or consensus to provide specific recommendations for glucose control in various CV diseases.In 2018, the Taiwan Society of Cardiology (TSOC) and the Diabetes Association of Republic of China (DAROC) published the first joint consensus on the "Pharmacological Management of Patients with Type 2 Diabetes and Cardiovascular Diseases." In 2020, TSOC appointed a new consensus group to revise the previous version. The updated 2020 consensus was comprised of 5 major parts: (1) treatment of diabetes in patients with multiple risk factors, (2) treatment of diabetes in patients with coronary heart disease, (3) treatment of diabetes in patients with stage 3 chronic kidney disease, (4) treatment of diabetes in patients with a history of stroke, and (5) treatment of diabetes in patients with heart failure. The members of the consensus group thoroughly reviewed all the evidence, mainly RCTs, and also included meta-analyses and real-world evidence. The treatment targets of HbA1c were finalized. The antidiabetic agents were ranked according to their clinical evidence. The consensus is not mandatory. The final decision may need to be individualized and based on clinicians' discretion.

Pioglitazone for primary stroke prevention in Asian patients with type 2 diabetes and cardiovascular risk factors: a retrospective study. Cardiovasc Diabetol 2020; 19:94. [PMID: 32563247 PMCID: PMC7306145 DOI: 10.1186/s12933-020-01056-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Accepted: 06/08/2020] [Indexed: 12/15/2022] Open
Abstract
Background Studies assessing the efficacy of pioglitazone solely for primary stroke prevention in Asian patients with type 2 diabetes mellitus (DM) and present multiple cardiovascular (CV) risk factors are rare. Thus, we aimed to assess the effect of pioglitazone on primary stroke prevention in Asian patients with type 2 DM without established CV diseases but with risk factors for CV diseases. Methods Between 2000 and 2012, we enrolled patients aged ≥ 18 years, who were newly diagnosed with type 2 diabetes and had at least one of the following CV risk factors: hypertension and hyperlipidemia. Patients with a history of stroke and those using insulin or glucagon-like peptide-1 agonist for more than 3 months were excluded. Patients were divided into the pioglitazone and non-pioglitazone groups based on their receipt of pioglitazone during the follow-up period. Propensity-score matching (1:1) was used to balance the distribution of the baseline characteristics and medications. Follow-up was terminated upon ischemic stroke development, withdrawal from the insurance system, or on December 31, 2013, whichever occurred first. The overall incidence of new-onset ischemic stroke in the two groups was subsequently compared. The subgroup analyses of ischemic stroke were conducted using different baseline features. Additionally, the effect of pioglitazone exposure dose on the occurrence of ischemic stroke was evaluated. Chi square test, Student’s t-test, competing risk regression models, Kaplan–Meier method, and log-rank test were some of the statistical tests conducted. Results A total of 13 078 patients were included in the pioglitazone and non-pioglitazone groups. Compared with patients who did not receive pioglitazone, those administered pioglitazone had a lower risk of developing ischemic stroke (adjusted hazard ratio: 0.78; 95% confidence interval: 0.62–0.95). The subgroup analyses defined by different baseline features did not reveal significant alterations in the observed effect of pioglitazone. Moreover, a significant decreasing trend in ischemic stroke risk with an increase in pioglitazone dose (p-value for trend = 0.04) was observed. Conclusion Pioglitazone use decreased the risk of new-onset ischemic stroke in Asian patients with type 2 DM and CV risk factors. Trial registration number CMUH104-REC2-115-CR4

Effect of saroglitazar 2 mg and 4 mg on glycemic control, lipid profile and cardiovascular disease risk in patients with type 2 diabetes mellitus: a 56-week, randomized, double blind, phase 3 study (PRESS XII study). Cardiovasc Diabetol 2020; 19:93. [PMID: 32560724 PMCID: PMC7305598 DOI: 10.1186/s12933-020-01073-w] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Accepted: 06/16/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The potential for PPAR agonists to positively affect risk of cardiovascular disease in patients with type 2 diabetes (T2DM) is of persistent attention. The PRESS XII study primarily aimed to evaluate the efficacy and safety of saroglitazar (2 mg and 4 mg) as compared to pioglitazone 30 mg on glycemic control in patients with type 2 diabetes mellitus. METHODS In this randomized double-blind study, patients with T2DM [glycosylated hemoglobin (HbA1c) ≥ 7.5%] were enrolled from 39 sites in India. Patients received once-daily doses of either saroglitazar or pioglitazone (1:1:1 allocation ratio) for a total of 24 weeks. Patients were continued in a double blind extension period for an additional 32 weeks. Efficacy evaluations of glycemic parameters [HbA1c (Primary endpoint at week 24), FPG and PPG] and other lipid parameters (TG, LDL-C, VLDL-C, HDL-C, TC, Non HDL-C, Apo A1 and Apo B) were conducted at week 12, 24 and 56 and compared to the baseline levels. The efficacy analyses were performed by using paired t-test and ANCOVA model. RESULTS A total of 1155 patients were enrolled in this study. The baseline characteristics were similar between the three treatment groups. The within group mean (± SD) change in HbA1c (%) from baseline of the saroglitazar (2 mg and 4 mg) and pioglitazone treatment groups at week 24 were: - 1.38 ± 1.99 for saroglitazar 2 mg; - 1.47 ± 1.92 for saroglitazar 4 mg and - 1.41 ± 1.86 for pioglitazone, respectively. Statistically significant reduction from baseline in HbA1c was observed in each treatment group at week 24 with p-value < 0.016. There was a significant reduction in TG, LDL-C, VLDL-C, TC and Non HDL-C with a significant increase in HDL-C from baseline levels (< 0.016). Most of the AE's were 'mild' to 'moderate' in severity and were resolved by the completion of the study. CONCLUSIONS Saroglitazar effectively improved glycemic control and lipid parameters over 56 weeks in patients of T2DM receiving background metformin therapy and has a promising potential to reduce the cardiovascular risk in T2DM patients.

Cardiovasc Diabetol 2020; 19:2. [PMID: 31910836 PMCID: PMC6945719 DOI: 10.1186/s12933-019-0979-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2019] [Accepted: 12/24/2019] [Indexed: 12/13/2022] Open
Abstract
Background and aim Peroxisome proliferator-activated receptor-γ (PPAR-γ) modulating treatment may have cardiovascular benefits in type 2 diabetes mellitus (T2DM) patients after ischemic stroke (IS). However, whether there are additional benefits from intensive PPAR-γ modulating treatments in Asian patients with T2DM and hypertension (HTN) after IS remains unknown. Methods Between 2001 and 2013, patients admitted due to IS were identified from the National Health Insurance Research Database of Taiwan. Patients with T2DM and HTN using angiotensin receptor blockers were further included. Eligible patients were divided into two groups: (1) pioglitazone and (2) non-pioglitazone oral anti-diabetic agent groups. Propensity score matching (1:2) was used to balance the distribution of baseline characteristics, stroke severity and medications. The primary outcome was recurrent IS. Subgroup analysis for recurrent IS in pioglitazone and/or telmisartan users, the trend of IS risks across different PPAR-γ intensity treatments, and dose-dependent outcomes across different pioglitazone possession ratios were further studied. Statistical significance was set at p < 0.05 and p < 0.1 for clinical outcomes and interaction of subgroup analyses, respectively. Results There were 3190 and 32,645 patients in the pioglitazone and non-pioglitazone groups. Patients of the pioglitazone group had a lower risk of recurrent IS (subdistribution hazard ratio, 0.91; 95% confidence interval 0.84–0.99). Pioglitazone was also associated with reduced recurrent IS in patients who also used telmisartan (p for interaction = 0.071). A graded correlation was found a borderline significant trend between the intensity of PPAR-γ therapy and following IS (p = 0.076). The dose-dependent outcome also showed that a borderline significant trend that higher pioglitazone possession ratio was associated with a lower risk of recurrent IS (p = 0.068). Conclusions The current study suggests that the use of pioglitazone in type 2 diabetic and hypertensive IS patients is associated with fewer recurrent IS events in an Asian population. Concurrent telmisartan use or a higher pioglitazone possession ratio may have a trend of increased pleiotropic effects, which could possibly be related to higher PPAR-γ effects. Future studies are warranted to confirm or refute the clinical effects and the possible mechanism of more intensive PPAR-γ-modulating treatments.
