Abstract
OBJECTIVE We aimed to investigate the relationship between coronary artery disease (CAD) and systemic inflammation indices and lipid metabolism-related factors and subsequently, discuss the clinical application of these factors in CAD. METHODS We enrolled 284 consecutive inpatients with suspected CAD and divided them into a CAD group and a non-CAD group according to coronary angiography results. Serum levels of angiopoietin-like protein 3 (ANGPTL3), angiopoietin-like protein 4 (ANGPTL4), fatty acid-binding protein 4 (FABP4), and tumor necrosis factor-α (TNF-α) levels were assessed using the ELISA and the systemic inflammation indices were calculated. Multivariate logistic regression was used to assess the risk factors of CAD. The receiver operating characteristic curve was used to determine the cutoff and diagnostic values. RESULTS The neutrophil-to-high density lipoprotein cholesterol ratio (5.04 vs. 3.47), neutrophil-to-lymphocyte ratio (3.25 vs. 2.45), monocyte-to-high density lipoprotein cholesterol ratio (MHR) (0.46 vs. 0.36), monocyte-to-lymphocyte ratio (0.31 vs. 0.26), systemic immune-inflammation index (SII) (696.00 vs. 544.82), serum TNF-α (398.15 ng/l vs. 350.65 ng/l), FABP4 (1644.00 ng/l vs. 1553.00 ng/l), ANGPTL3 (57.60 ng/ml vs. 52.85 ng/ml), and ANGPTL4 (37.35 ng/ml vs. 35.20 ng/ml) values showed a significant difference between the CAD and non-CAD groups ( P < 0.05). After adjusting for confounding factors, the following values were obtained: ANGPTL3 > 67.53 ng/ml [odds ratio (OR) = 8.108, 95% confidence interval (CI) (1.022-65.620)]; ANGPTL4 > 29.95 ng/ml [OR = 5.599, 95% CI (1.809-17.334)]; MHR > 0.47 [OR = 4.872, 95% CI (1.715-13.835)]; SII > 589.12 [OR = 5.131, 95% CI (1.995-13.200)]. These factors were found to be independently associated with CAD ( P < 0.05). Diabetes combined with MHR > 0.47, SII > 589.12, TNF-α >285.60 ng/l, ANGPTL3 > 67.53 ng/ml, and ANGPTL4 > 29.95 ng/l had the highest diagnostic value for CAD [area under the curve: 0.921, 95% CI, (0.881-0.960), Sensitivity: 88.9%, Specificity: 82.2%, P < 0.001]. CONCLUSION MHR > 0.47, SII > 589.12, TNF-α >285.60 ng/l, ANGPTL3 > 67.53 ng/ml, and ANGPTL4 > 29.95 ng/l were identified as independent CAD risk factors and have valuable clinical implications in the diagnosis and treatment of CAD.

Abstract
OBJECTIVE To establish a predictive model for poor prognosis after incomplete revascularization (ICR) in patients with multivessel coronary artery disease (MVD). METHODS Clinical data of 757 patients with MVD and ICR after percutaneous coronary intervention (PCI) in the Affiliated Hospital of Chengde Medical University from January 2020 to August 2021 were retrospectively collected. The least absolute shrinkage and selection operator regression method was used to screen variables, and multivariate logistic regression was used to establish a predictive model. An independent cohort was used to validate the model. The C-statistic was used to verify and evaluate the discriminative ability of the model; the calibration curve was drawn, and the decision curve analysis (DCA) was performed to evaluate the calibration degree, the clinical net benefit, and the practicability of the model. RESULTS The predictive factors included female, age, unconjugated bilirubin, uric acid, low-density lipoprotein, hyperglycemia, total occlusion, and severe tortuosity lesion on coronary angiography. The C-statistic of the training and validation sets were 0.628 and 0.745, respectively. The statistical value of the Hosmer-Lemeshow test for the calibration curve of the training and validation sets were 5.27(P = 0.873) and 6.27 (P = 0.792), respectively. DCA showed that the model was clinically applicable when the predicted probability value of major adverse cardiovascular events(MACEs) ranged from 0.07 to 0.68. CONCLUSIONS We established a predictive model for poor prognosis after ICR in patients with MVD. The predictive and calibration ability and the clinical net benefit of the predictive model were good, indicating that it can be used as an effective tool for the early prediction of poor prognosis after ICR in patients with MVD.

Abstract
OBJECTIVE The objective of this clinical practice guideline is to provide updated and new evidence-based recommendations for the comprehensive care of persons with diabetes mellitus to clinicians, diabetes-care teams, other health care professionals and stakeholders, and individuals with diabetes and their caregivers. METHODS The American Association of Clinical Endocrinology selected a task force of medical experts and staff who updated and assessed clinical questions and recommendations from the prior 2015 version of this guideline and conducted literature searches for relevant scientific papers published from January 1, 2015, through May 15, 2022. Selected studies from results of literature searches composed the evidence base to update 2015 recommendations as well as to develop new recommendations based on review of clinical evidence, current practice, expertise, and consensus, according to established American Association of Clinical Endocrinology protocol for guideline development. RESULTS This guideline includes 170 updated and new evidence-based clinical practice recommendations for the comprehensive care of persons with diabetes. Recommendations are divided into four sections: (1) screening, diagnosis, glycemic targets, and glycemic monitoring; (2) comorbidities and complications, including obesity and management with lifestyle, nutrition, and bariatric surgery, hypertension, dyslipidemia, retinopathy, neuropathy, diabetic kidney disease, and cardiovascular disease; (3) management of prediabetes, type 2 diabetes with antihyperglycemic pharmacotherapy and glycemic targets, type 1 diabetes with insulin therapy, hypoglycemia, hospitalized persons, and women with diabetes in pregnancy; (4) education and new topics regarding diabetes and infertility, nutritional supplements, secondary diabetes, social determinants of health, and virtual care, as well as updated recommendations on cancer risk, nonpharmacologic components of pediatric care plans, depression, education and team approach, occupational risk, role of sleep medicine, and vaccinations in persons with diabetes. CONCLUSIONS This updated clinical practice guideline provides evidence-based recommendations to assist with person-centered, team-based clinical decision-making to improve the care of persons with diabetes mellitus.

Abstract
AIM In 2019, the Italian Society of Diabetology and the Italian Association of Clinical Diabetologists nominated an expert panel to develop guidelines for drug treatment of type 2 diabetes. After identifying the effects of glucose-lowering agents on major adverse cardiovascular events (MACEs), all-cause mortality, and hospitalization for heart failure (HHF) as critical outcomes, the experts decided to perform a systematic review and meta-analysis on the effect of pioglitazone with this respect. DATA SYNTHESIS A MEDLINE database search was performed to identify RCTs, up to June 1st, 2021, with duration≥52 weeks, in which pioglitazone was compared with either placebo or active comparators. The principal endpoints were MACE and HHF (restricted for RCT reporting MACEs within their outcomes), all-cause mortality (irrespective of the inclusion of MACEs among the pre-specified outcomes). Mantel-Haenszel odds ratio (MH-OR) with 95% Confidence Interval (95% CI) was calculated for all the endpoints considered. Eight RCTs were included in the analysis for MACEs and HF (5048 and 5117 patients in the pioglitazone and control group, respectively), and 24 in that for all-cause mortality (10,682 and 9674 patients). Pioglitazone neither significantly increased nor reduced the risk of MACE, all-cause mortality, and HHF in comparison with placebo/active comparators (MH-OR: 0.90, 95% CI 0.78-1.03, 0.91, 95% CI 0.77, 1.09, and 1.16, 95% CI 0.73, 1.83, respectively). Pioglitazone was associated with a significant reduction of MACE in patients with prior cardiovascular events (MH-OR 0.84, 95% CI 0.72-0.99). CONCLUSIONS This meta-analysis showed no significant effects of pioglitazone on incident MACE, all-cause mortality, and HHF.

Abstract
BACKGROUND Patients with diabetes have a higher risk of requiring repeated percutaneous coronary intervention (PCI) than non-diabetic patients. We aimed to evaluate and compare the effects of anti-diabetic drugs on the secondary prevention of myocardial infarction among type 2 diabetes mellitus patients. METHODS We analyzed the general health check-up dataset and claims data of the Korean National Health Insurance Service of 199,714 participants (age ≥30 years) who underwent PCIs between 2010 and 2013. Those who underwent additional PCI within 1 year of their first PCI (n=3,325) and those who died within 1 year (n=1,312) were excluded. Patients were classified according to their prescription records for glucose-lowering agents. The primary endpoint was the incidence rate of coronary revascularization. RESULTS A total of 35,348 patients were included in the study. Metformin significantly decreased the risk of requiring repeat PCI in all patients (adjusted hazard ratio [aHR], 0.77). In obese patients with body mass index (BMI) ≥25 kg/m2, patients treated with thiazolidinedione (TZD) exhibited a decreased risk of requiring repeat revascularization than those who were not treated with TZD (aHR, 0.77; 95% confidence interval, 0.63 to 0.95). Patients treated with metformin showed a decreased risk of requiring revascularization regardless of their BMI. Insulin, meglitinide, and alpha-glucosidase inhibitor were associated with increased risk of repeated PCI. CONCLUSION The risk of requiring repeat revascularization was lower in diabetic patients treated with metformin and in obese patients treated with TZD. These results suggest that physicians should choose appropriate glucose-lowering agents for the secondary prevention of coronary artery disease.

Abstract
Type 2 diabetes individuals are at high risk for macrovascular complications: myocardial infarction, stroke and cardiovascular mortality. Recent cardiovascular outcome trials have demonstrated that agents in two antidiabetic classes (SGLT2 inhibitors and GLP-1 receptor agonists) reduce major adverse cardiovascular events. However, there is strong evidence that an older and now generically available medication, the thiazolidinedione, pioglitazone, can retard the atherosclerotic process (PERISCOPE and Chicago) and reduce cardiovascular events in large randomized prospective cardiovascular outcome trials (IRIS and PROactive). Pioglitazone is a potent insulin sensitizer, preserves beta-cell function, causes durable reduction in HbA1c, corrects multiple components of metabolic syndrome and improves nonalcoholic fatty liver disease/nonalcoholic steatohepatitis. Adverse effects (weight gain, fluid retention, fractures) must be considered, but are diminished with lower doses and are arguably outweighed by these multiple benefits. With healthcare expenses attributable to diabetes increasing rapidly, this cost-effective drug requires reconsideration in the therapeutic armamentarium for the disease.

Abstract
Type 2 diabetes (T2DM) is a leading cause of morbidity and mortality worldwide and a major economic burden. The prevalence of T2DM is rising, suggesting more effective prevention and treatment strategies are necessary. The aim of this narrative review is to summarize the pharmacologic treatment options available for patients with T2DM. Each therapeutic class is presented in detail, outlining medication effects, side effects, glycemic control, effect on weight, indications and contraindications, and use in selected populations (heart failure, renal insufficiency, obesity and the elderly). We also present representative cost for each antidiabetic category. Then, we provide an individualized guide for initiation and intensification of treatment and discuss the considerations and rationale for an individualized glycemic goal.

Different Effects of Thiazolidinediones on In-Stent Restenosis and Target Lesion Revascularization after PCI: A Meta-Analysis of Randomized Controlled Trials. Sci Rep 2017; 7:14464. [PMID: 29089560 PMCID: PMC5663835 DOI: 10.1038/s41598-017-14873-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2017] [Accepted: 10/17/2017] [Indexed: 12/12/2022] Open
Abstract
In-stent restenosis (ISR) remains the leading problem encountered after percutaneous coronary intervention (PCI). Thiazolidinediones (TZDs) has been shown to be associated with reduced ISR and target lesion revascularization (TLR); however, the results are inconsistent, especially between rosiglitazone and pioglitazone. In this study, fourteen RCTs with a total of 1350 patients were finally included through a systematical literature search of Embase, Pubmed, the Cochrane Library, and ClinicalTrials.gov from inception to January 31, 2017. The follow-up duration of the included trials ranged from 6 months to 18 months. The results demonstrated that TZDs treatment is associated with significantly reduced risk of TLR (RR:0.45, 95%CI 0.30 to 0.67 for pioglitazone, RR:0.68, 95%CI 0.46 to 1.00 for rosiglitazone). Pioglitazone is associated with significantly reduced risks of ISR (RR:0.47, 95%CI 0.27 to 0.81), major adverse cardiac events (MACE) (RR:0.44, 95%CI 0.30 to 0.64) and neointimal area (SMD: −0.585, 95%CI −0.910 to −0.261). No significant relationship was observed between rosiglitazone and ISR (RR:0.91, 95%CI 0.39 to 2.12), MACE (RR:0.73, 95%CI 0.53 to 1.00) and neointimal area (SMD: −0.164, 95%CI −1.146 to 0.818). This meta-analysis demonstrated that TZDs treatment is associated with significant reduction in ISR, TLR and MACE for patients after PCI. Pioglitazone treatment seems to have more beneficial effects than rosiglitazone and no significantly increased cardiovascular risk was detected for both agents.

Pioglitazone Ameliorates Smooth Muscle Cell Proliferation in Cuff-Induced Neointimal Formation by Both Adiponectin-Dependent and -Independent Pathways. Sci Rep 2016; 6:34707. [PMID: 27703271 PMCID: PMC5050439 DOI: 10.1038/srep34707] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2016] [Accepted: 08/15/2016] [Indexed: 01/11/2023] Open
Abstract
The aim of this study is to elucidate to what degree adiponectin is involved in TZD-mediated amelioration of neointimal formation. We investigated the effect of 3- or 8-weeks' pioglitazone on cuff-induced neointimal formation in adiponectin-deficient (APN-KO) and wild-type (WT) mice. Pioglitazone for 3 weeks reduced neointimal formation in the WT mice with upregulation of the plasma adiponectin levels, but failed to reduce neointimal formation in the APN-KO mice, suggesting that pioglitazone suppressed neointimal formation by adiponectin-dependent mechanisms. Pioglitazone for 3 weeks suppressed vascular smooth muscle cell (VSMC) proliferation and increased AdipoR2 expression in the WT mice. In vitro, globular adiponectin activated AMPK through both AdipoR1 and AdipoR2, resulting in the inhibition of VSMC proliferation. Interestingly, 8-weeks' pioglitazone was reduced neointimal formation in APN-KO mice to degree similar to that seen in the WT mice, suggesting that pioglitazone can also suppress neointimal formation via a mechanism independent of adiponectin. Pioglitazone for 8 weeks completely abrogated the increased VSMC proliferation, along with a reduction of cyclin B1 and cyclin D1 expressions and cardiovascular risk profile in the APN-KO mice. In vitro, pioglitazone suppressed these expressions, leading to inhibition of VSMC proliferation. Pioglitazone suppresses neointimal formation via both adiponectin-dependent and adiponectin-independent mechanisms.

Abstract
BACKGROUND In-stent restenosis (ISR) remains a common life-threatening complication and some studies have shown that pioglitazone can reduce the incidence of ISR in patients with drug-eluting stents (DES) implantation. We conducted a meta-analysis to assess the effect of pioglitazone in preventing ISR after DES implantation. METHODS Randomized controlled trials (RCTs) investigating the effects of pioglitazone for ISR after DES implantation were identified by systematic searches of multiple online databases and manual searches of related reference lists of identified trials through May 2014. The primary endpoint was the rate of ISR. Secondary endpoints included minimum lumen diameter, percentage stenosis of stented vessels, late loss, in-stent neointimal volume, target vessel revascularization (TVR), target lesion revascularization, myocardial infarction, stent thrombosis and death. RESULTS Five studies, comprising 255 pioglitazone-treated patients and 245 controls, were identified in the current meta-analysis. Pioglitazone did not significantly reduce the rate of ISR (P = 0.20) with low heterogeneity (I2 = 13.3%, P = 0.32). For the secondary outcomes, pioglitazone did not substantially affect the pooled estimates of these endpoints except late loss (P = 0.01) and TVR (P = 0.04). CONCLUSIONS The limited evidence indicates that pioglitazone does not demonstrate markedly beneficial effect in patients subjected to coronary DES implantation. However, the results should be interpreted with care given the small sample size. Further large-scale RCTs are needed.

Abstract
Much has been written regarding the recently discontinued Thiazolidinedione Intervention with Vitamin D Evaluation (TIDE) trial (ClinicalTrials.gov NCT00879970; Diabetologia 55: 36-45) and a variety of opinions have been advanced regarding its purpose, context and design (N Engl J Med 397: 959-964). As such, we deemed it appropriate to clarify TIDE's objectives, research questions and design and the clinical equipoise regarding its research questions.

Abstract
Insulin resistance is a key pathogenic defect of the clustered metabolic disturbances seen in polycystic ovary syndrome (PCOS). Metformin is an insulin sensitizer acting in the liver and the peripheral tissues that ameliorates the metabolic and reproductive defects in PCOS. In addition, pioglitazone is an insulin sensitizer used in diabetes mellitus type 2 (T2DM), improving insulin resistance (IR) in adipose tissue and muscles. In T2DM, these drugs are also used as a combined treatment due to their "add-on effect" on insulin resistance. Although the beneficial role of troglitazone (a member of the thiazolidinediones (TZDs) family) in PCOS has been shown in the past, currently only pioglitazone is available in the market. A few small randomized controlled trials have directly compared the effectiveness of pioglitazone in women with PCOS, while there are a limited number of small studies that support the beneficial metabolic add-on effect of pioglitazone on metformin-treated PCOS women as compared to metformin or pioglitazone monotherapy. These findings suggest a potentially promising role for combined pioglitazone/metformin treatment in the management of PCOS in metformin-resistant patients. In view of recent concerns regarding pioglitazone usage and its associated health risk, we aim to compare the pros and cons of each drug regarding their metabolic and other hormonal effects in women with PCOS and to explore the possible beneficial effect of combined therapy in certain cases, taking into consideration the teratogenic effect of pioglitazone. Finally, we discuss the need for a randomized controlled trial that will evaluate the metabolic and other hormonal effects of combined metformin/pioglitazone treatment in PCOS with selective treatment targets.

Abstract
Since their approval, thiazolidinediones (TZDs) have been used extensively as insulin-sensitizers for the management of type 2 diabetes mellitus (T2DM). Activation of peroxisomal proliferator-activated receptor gamma (PPARγ) nuclear receptors by TZDs leads to a vast spectrum of metabolic and antiinflammatory effects. In the past decade, clinicians and scientists across the fields of metabolism, diabetes, liver disease (NAFLD), atherosclerosis, inflammation, infertility, and even cancer have had high hopes about the potential for TZDs to treat many of these diseases. However, an increasing awareness about undesirable "off-target" effects of TZDs have made us rethink their role and be more cautious about the long-term benefits and risks related to their use. This review examines the most relevant work on the benefits and risks associated with TZD treatment, with a focus on the only PPARγ agonist currently available (pioglitazone), aiming to offer the reader a balanced overview about the current and future role of TZDs in the management of insulin-resistant states and T2DM.

Abstract
Peroxisome proliferator-activated receptor γ (PPAR-γ) is a key regulator of fatty acid metabolism, promoting its storage in adipose tissue and reducing circulating concentrations of free fatty acids. Activation of PPAR-γ has favorable effects on measures of adipocyte function, insulin sensitivity, lipoprotein metabolism, and vascular structure and function. Despite these effects, clinical trials of thiazolidinedione PPAR-γ activators have not provided conclusive evidence that they reduce cardiovascular morbidity and mortality. The apparent disparity between effects on laboratory measurements and clinical outcomes may be related to limitations of clinical trials, adverse effects of PPAR-γ activation, or off-target effects of thiazolidinedione agents. This review addresses these issues from a clinician's perspective and highlights several ongoing clinical trials that may help to clarify the therapeutic role of PPAR-γ activators in cardiovascular disease.

Effects of thiazolidinediones on cardiovascular events in patients with type 2 diabetes mellitus after drug-eluting stent implantation: a retrospective cohort study using the national health insurance database in Taiwan. Clin Ther 2012; 34:885-93. [PMID: 22440193 DOI: 10.1016/j.clinthera.2012.02.024] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2011] [Revised: 02/22/2012] [Accepted: 02/23/2012] [Indexed: 11/20/2022]
Abstract
BACKGROUND Thiazolidinediones (TZDs) may reduce in-stent restenosis and improve clinical outcomes in type 2 diabetic patients after bare-metal stent implantation. However, it is still unknown whether diabetic patients with drug-eluting stents (DESs) could benefit from treatment with TZDs. OBJECTIVE The objective was to evaluate the clinical outcomes of TZDs in type 2 diabetic patients within 1 year of receiving DESs. METHODS This retrospective cohort study was performed in 1743 Taiwanese type 2 diabetic patients (1137 men; 606 women) who received DESs between December 1, 2006 and December 31, 2007. Patients were classified into TZD (n = 268) or non-TZD groups (n = 1,475) using medication records within 3 months of the index hospitalization. Follow-up data were available through December 31, 2008. Clinical outcome measurements included death, myocardial infarction (MI), and repeat revascularization within 1 year after the index date of hospitalization. Cox proportional hazards model and other analyses were performed for the study. RESULTS For the TZD and non-TZD groups, the mean ages were 65.07 and 66.09 years, respectively, for those with limus-eluting stents (LESs) and 65.61 and 65.81 years, respectively, for those with paclitaxel-eluting stents (PESs). With or without TZD medication, there were no significant differences in the adjusted hazard ratios of death, MI, or repeat revascularization for diabetic patients who received LESs or PESs. TZD treatment in patients who received LESs and had a history of MI was associated with a higher risk of MI (hazard ratio = 5.292; 95% CI, 1.028-27.232). CONCLUSIONS TZDs did not improve the clinical outcomes in Taiwanese type 2 diabetes patients who received DESs. TZDs might have been a contributor to higher risk of MI in patients with LESs and a history of MI. Larger clinical trials are still needed to study this issue further.

Abstract
AIMS/OBJECTIVE Conflicting data regarding cardiovascular effects of thiazolidinediones (TZDs) and extra-skeletal effects of vitamin D supported the need for a definitive trial. The Thiazolidinedione Intervention with vitamin D Evaluation (TIDE) trial aimed to assess the effects of TZDs (rosiglitazone and pioglitazone) on cardiovascular outcomes and the effects of vitamin D (cholecalciferol) on cancers and mortality. METHODS A large multicentre 3 × 2 factorial double-blind placebo-controlled randomised trial recruited from outpatient primary care and specialty clinics in 33 countries. From June 2009 to July 2010, 1,332 people with type 2 diabetes and other cardiovascular risk factors aged ≥ 50 years whose HbA(1c) was 6.5-9.5% (48-80 mmol/mol) when using two or fewer glucose-lowering drugs were randomised by a central computer system to placebo (n = 541), rosiglitazone 4-8 mg/day (n = 399) or pioglitazone 30-45 mg/day (n = 392); 1,221 participants were randomised to placebo (n = 614) or vitamin D 1,000 IU/day (n = 607). Participants and all study personnel were blind to treatment allocation. The primary outcome for the TZD arm was the composite of myocardial infarction, stroke or cardiovascular death, and for the vitamin D arm it was cancer or all-cause death. All randomised participants were included in the primary analysis. RESULTS From the study design, 16,000 people were to be followed for approximately 5.5 years. However, the trial was stopped prematurely because of regulatory concerns after a mean of 162 days without consideration of the accrued data. In the TZD arm, the cardiovascular outcome occurred in five participants (0.9%) in the placebo groups and three participants (0.4%) in the TZD groups (two allocated to pioglitazone, one to rosiglitazone). In the vitamin D arm, the primary outcome occurred in three participants (0.5%) in the placebo group and in two participants (0.3%) receiving vitamin D. Adverse events were comparable in all groups. CONCLUSIONS/INTERPRETATION Uncertainty persists regarding the clinically relevant risks and benefits of TZDs and vitamin D because of the early cancellation of this comprehensive trial.

Abstract
Proliferation of vascular smooth muscle cells (SMCs) is a critical process for the development of atherosclerosis and complications of procedures used to treat atherosclerotic diseases, including postangioplasty restenosis, vein graft failure, and transplant vasculopathy. Peroxisome proliferator-activated receptor (PPAR) gamma is a member of the nuclear hormone receptor superfamily and the molecular target for the thiazolidinediones (TZD), used clinically to treat insulin resistance in patients with type 2 diabetes. In addition to their efficacy to improve insulin sensitivity, TZD exert a broad spectrum of pleiotropic beneficial effects on vascular gene expression programs. In SMCs, PPARgamma is prominently upregulated during neointima formation and suppresses the proliferative response to injury of the arterial wall. Among the molecular target genes regulated by PPARgamma in SMCs are genes encoding proteins involved in the regulation of cell-cycle progression, cellular senescence, and apoptosis. This inhibition of SMC proliferation is likely to contribute to the prevention of atherosclerosis and postangioplasty restenosis observed in animal models and proof-of-concept clinical studies. This review will summarize the transcriptional target genes regulated by PPARgamma in SMCs and outline the therapeutic implications of PPARgamma activation for the treatment and prevention of atherosclerosis and its complications.

Abstract
AIMS The aim of this study was to examine outcome subsequent to implantation of bare-metal stents (BMS) with pioglitazone, which are novel insulin-sensitizing agents, and drug-eluting stents (DES) in patients with diabetes. METHODS AND RESULTS A total of 139 consecutive Type 2 diabetic patients treated with stent were followed up for 3 years. Data on death, myocardial infarction (MI), target lesion revascularization (TLR), and stent thrombosis were ascertained from January 2003 to January 2006. Eighty-nine patients were treated with a BMS with pioglitazone, and 50 patients were treated with a DES. The incidence of MI was 1.1% in the BMS with pioglitazone group, 4.0% in the DES group [relative risk RR):0.52; 95% CI: 0.10-2.56]. The incidence of TLR was 22.5% in the BMS with pioglitazone group, 28.0% in the DES group (RR 0.89; 95% CI: 0.65-1.22). The incidence of stent thrombosis was 1.0% in the BMS with pioglitazone group, 4.0% in the DES group (RR 0.52; 95% CI: 0.10-2.56). Overall 3-year mortality was similar in the two groups (RR 0.77; 95% CI: 0.34-1.74). CONCLUSIONS During 3 years of follow-up, patients treated with BMS with pioglitazone had similar risks of death, TLR, MI, and stent thrombosis compared with patients treated with DES.

Abstract
Diabetes mellitus leads to the development of a host of micro- and macrovascular complications, which collectively lead to substantial morbidity and mortality. Among the microvascular complications of diabetes, diabetic kidney disease is the most common. Macrovascular complications from diabetes lead to a 2- to 4-fold increase in the incidence of cardiovascular disease and up to twice the mortality from cardiovascular causes as compared with nondiabetic individuals. This article discusses the various drug classes used to treat diabetes mellitus, and reviews the current clinical evidence linking glycemic control using these drug classes on diabetic kidney and cardiovascular disease.

Abstract
UNLABELLED NARRATIVE REVIEW: Myopathy, fracture, tendon rupture, and neuropathy are severe physical adverse effects associated with commonly prescribed medications. Recognition of and exercise adjustment for these medication-induced effects by the therapist is essential to providing adequate care. The normal structure and function of muscle, tendon, cartilage, or bone may be altered by medications, leading to significant disability. The number of patients presenting to therapists with medication-induced physical complaints is rising with increases in medication utilization. Therapists should be involved in adverse effect risk reduction by 1) identification and reporting of potential adverse medication reactions, 2) adjustment of exercise regimen when the patient is on a medication with potential damaging effects on tendon, muscle, or cartilage, and 3) vigilant screening for medication-induced myopathies, fractures, neuropathies, and tendinopathies. Although many medications induce physical adverse effects, understanding the most serious musculoskeletal effects of commonly prescribed medications is critical for therapists. LEVEL OF EVIDENCE 5.

Abstract
BACKGROUND AND AIM Pioglitazone has diverse multiple effects on metabolic and inflammatory processes that have the potential to influence cardiovascular disease pathophysiology at various points in the disease process, including atherogenesis, plaque inflammation, plaque rupture, haemostatic disturbances and microangiopathy. RESULTS Linking the many direct and indirect effects on the vasculature to the reduction in key macrovascular outcomes reported with pioglitazone in patients with type 2 diabetes presents a considerable challenge. However, recent large-scale clinical cardiovascular imaging studies are beginning to provide some mechanistic insights, including a potentially important role for improvements in high-density lipoprotein cholesterol with pioglitazone. In addition to a role in prevention, animal studies also suggest that pioglitazone may minimize damage and improve recovery during and after ischaemic cardio- and cerebrovascular events. DESIGN AND METHODS In this review, we consider potential cardiovascular protective mechanisms of pioglitazone by linking preclinical data and clinical cardiovascular outcomes guided by insights from recent imaging studies. CONCLUSION Pioglitazone may influence CVD pathophysiology at multiple points in the disease process, including atherogenesis, plaque inflammation, plaque rupture and haemostatic disturbances (i.e. thrombus/embolism formation), as well as microangiopathy.

Abstract
Thiazolidinediones (TZDs), agonists of the nuclear receptor peroxisome proliferator-activated receptor-gamma, induce the expression of many genes, including several enzymes and transporters involved in glucose and lipid metabolism. Although the efficacy of TZDs on blood glucose control in type 2 diabetes is not questionable, their cardiovascular effects have been debated, with beneficial or harmful actions suggested by different authors. This article reviews the available clinical evidence on the cardiovascular effects of TZDs, discussing possible mechanisms underlying the observed effects and suggesting some directions for future research.

Abstract
BACKGROUND Progressive beta-cell dysfunction and beta-cell failure are fundamental pathogenic consequences of type 2 diabetes. Dipeptidyl peptidase-IV inhibitors may exhibit improvement on preclinical measures of both beta-cell function, homeostasis model assessment of beta-cell (HOMA-beta) index, and beta-cell dysfunction, proinsulin/insulin ratio (PI/IR), correlating to beta-cell survival. RESEARCH DESIGN AND METHODS A systematic literature search through July 2008 was conducted to extract a consensus of randomized, controlled trials of sitagliptin therapy on measures of beta-cell function. A random-effects model meta-analysis evaluated effects on HOMA-beta and PI/IR versus placebo. Several subgroup analyses, including active control, were conducted. Studies were included if they met the following criteria: (1) randomized trials on sitagliptin; (2) placebo or active control; and (3) data reported on HOMA-beta or PI/IR. RESULTS A total of 11 trials (n = 3039) reported effects on HOMA-beta and 8 trials (n = 2325) on PI/IR versus placebo. Four trials (n = 1425) were included in the active control subgroup analysis. Sitagliptin significantly improved HOMA-beta index by 12.03% [95% confidence interval (CI), 9.45-14.60] versus placebo. Sitagliptin also significantly decreased PI/IR -0.06 (95% CI, -0.08 to -0.04). Sitagliptin was inferior to active control for HOMA-beta index [5.64% (95% CI, 0.38-10.90)], but not different in terms of PI/IR [0.01 (95% CI, -0.04 to 0.06)]. CONCLUSIONS Despite significant improvement in HOMA-beta index and PI/IR from placebo, there does not seem to be a benefit of dipeptidyl peptidase-IV inhibitors over other agents with respect to beta-cell function/activity. Long-term prevention of beta-cell dysfunction cannot be ruled out.

Abstract
BACKGROUND The thiazolidinediones pioglitazone and rosiglitazone have established efficacy in improving insulin sensitivity, glycaemic control, dyslipidaemia, hypertension and microalbuminuria in patients with type 2 diabetes. As specific agonists of peroxisome proliferator-activated receptor-gamma, thiazolidinediones have also demonstrated protective effects on a variety of atherosclerosis biomarkers and surrogate measures of cardiovascular disease. AIM This paper reviews the evidence for pleiotropic effects on a variety of non-traditional atherosclerotic risk factors. DISCUSSION Thiazolidinediones attenuate circulating levels of pro-inflammatory mediators in patients with type 2 diabetes, including C-reactive protein, interleukin-6, CD40L, monocyte chemoattractant protein-1 and metalloproteinase-9. These agents also increase levels of the vascular protective adipokine, adiponectin. The clinical significance of these findings is supported by evidence of improved endothelial dysfunction, reduced carotid intima media thickness and improvements in stenosis following coronary artery stent implantation in patients treated with thiazolidinediones. Limited data suggest that thiazolidinediones might also improve the circulating levels and functional activity of angiogenic endothelial progenitor cells, which independently predict the incidence of cardiovascular events and death. It should be noted that the US Food and Drug Administration and the European Medicines Agency have requested changes to the prescribing information for rosiglitazone to highlight the possibility of an increased risk with this agent in patients with ischaemic heart disease; on review, no such amendment was required for the pioglitazone prescribing information. Both agencies continue to suggest that the benefits of both thiazolidinediones outweight any possible detrimental effects. Further research remains to be conducted to elucidate the potentially differential vascular protective effects of thiazolidinediones. In the US, there are black box heart failure warnings for both agents. CONCLUSION In light of the established importance of reducing cardiovascular risk in patients with type 2 diabetes, current evidence continues to support the use of pioglitazone within multifactorial risk management strategies.

Abstract
AIM The aim of this meta-analysis of randomized clinical trials (RCT) was to assess whether pioglitazone is also associated with increased cardiovascular risk, as recently reported for rosiglitazone. METHODS RCT of pioglitazone were retrieved from Medline (any date up to 31 August 2007; English language only). Unpublished RCT were identified through http://www.clinicaltrials.gov or http://www.fda.gov websites, and results on cardiovascular outcomes were retrieved from investigators and/or sponsors, whenever possible. RCT were included in meta-analysis if pioglitazone was compared with other treatments (placebo, active comparators or no treatment) for at least 4 weeks. Ninety-four trials, 10 of which were unpublished, were retrieved; those included in the analysis, which excluded PROspective PioglitAzone Clinical Trial In MacroVascular Events (PROACTIVE), enrolled 11 268 and 9912 patients in the pioglitazone and comparator groups respectively. Data for analysis, extracted independently by two observers, included all-cause and cardiovascular mortality and incidence of non-fatal coronary events and heart failure. Proportions of outcome measures across treatment groups were compared by odds ratios (ORs) and 95% confidence interval. RESULTS Pioglitazone was associated with reduced all-cause mortality [OR 0.30 (0.14-0.63); p < 0.05], with no relevant effect on non-fatal coronary events. The observed increase in incidence of non-fatal heart failure was not statistically significant [OR 1.38 (0.90-2.12)]. CONCLUSION The use of pioglitazone does not appear to be harmful in terms of cardiovascular events and all-cause deaths.

Abstract
The treatment with rosiglitazone could be associated with increased risk for myocardial infarction (MI). This meta-analysis is aimed at identifying moderators of the effect of rosiglitazone on the risk of MI and chronic heart failure (CHF) in type 2 diabetic patients. The risk ratio (RR) of MI and CHF was calculated for each trial as the ratio of incidence density in rosiglitazone and comparator groups. A total of 86 trials were included. After adjusting for trial duration, RR for MI showed a significant inverse correlation with mean baseline HbA1c, triglycerides, and LDL-cholesterol (r=-0.24, -0.45, and -0.33, respectively; all p<0.05). Conversely, rosiglitazone-associated risk of MI was increased in trials with higher mean BMI or greater proportion of insulin-treated patients (r=0.26 and 0.42, respectively; p<0.05). Lower triglyceride levels were also associated with a higher rosiglitazone-induced risk of CHF (r=-0.23, p<0.05). Treatment with rosiglitazone could have divergent effects on cardiovascular risk, depending on the characteristics of the patients. Benefits could outweigh harms in patients with poor glycemic control and worse lipid profile; conversely, the drug could increase the risk of MI in obese or insulin-treated patients.

Abstract
OBJECTIVE To examine the cardiovascular effects of thiazolidinediones (TZDs), discuss concerns regarding this drug class and its relation to heart failure (HF) and myocardial infarction (MI), and address the clinical implications of HF and MI. DATA SOURCES Literature was accessed through MEDLINE (1979-April 2008) using the search terms type 2 diabetes mellitus, thiazolidinediones, cardiovascular events, heart failure, myocardial infarction, and edema. Reviews, meta-analyses, clinical trials, observational studies (case-control, cohort), and descriptive studies (case reports, case series) were included. STUDY SELECTION AND DATA EXTRACTION All articles that were written in English and identified from the data sources were reviewed. DATA SYNTHESIS The American Diabetes Association recommends metformin as first-line therapy for type 2 diabetes, with the subsequent addition of a TZD, sulfonylurea, or insulin if the target is not met. Beyond glucose lowering, TZDs improve various factors associated with cardiovascular risk. Whether the effects translate into beneficial cardiovascular outcomes is controversial. In PROactive (Prospective Pioglitazone Clinical Trial in Macrovascular Events), pioglitazone did not produce a significant reduction in the primary endpoint that included a composite of coronary and vascular deaths, but the secondary composite endpoint of all-cause mortality, MI, or stroke was significantly reduced. Concerns related to HF have led to warnings in the labeling of TZDs. The drugs are contraindicated in patients with New York Heart Association Class III or IV HF. Rosiglitazone, but not pioglitazone, is associated with an increased risk of myocardial ischemic events, although the absolute magnitude is extremely small. CONCLUSIONS Although the glycemic efficacy of TZDs is comparable to that of metformin, adverse effects and higher costs make TZDs less appealing for initial therapy. Among the TZDs, pioglitazone should be considered based on cardiovascular safety data. In combination with metformin, pioglitazone may be particularly beneficial for patients with diabetes and metabolic syndrome. For patients on rosiglitazone who are achieving glycemic goals and tolerating the therapy without apparent complications, rosiglitazone may be continued.

Abstract
Objectives To analyse the effects of rosiglitazone administered at different times on neointimal formation in hypercholesterolemic rabbits following vascular injury. Methods Thirty-nine rabbits on a hypercholesterolemic diet were included. The animals underwent balloon catheter injury to the right iliac artery on day 14. They were divided into three groups as follows: control group, 13 rabbits without rosiglitazone; group I, 13 rabbits treated with rosiglitazone (3 mg/Kg body weight/day) for 28 days after the vascular injury; and group II, 13 rabbits treated with rosiglitazone (3 mg/Kg body weight/day) during all the experiment (42 days). Histological analysis was done by an experienced pathologist who was unaware of the rosiglitazone treatment. Histomorphometric parameters were performed by calculation of the luminal and intimal layer area, and intima/media layer area ratio (the area of the intimal layer divided by the area of the medial layer). Results Intimal area was significantly lower in group II vs. CG (p = 0.024) and group I (p = 0.006). Luminal layer area was higher in group II vs. CG (p < 0.0001) and group I (p < 0.0001). Intima/media layer area ratio was equal between CG and group I. Intima/media layer ratio area was significantly lower in group II vs. control group (p < 0.021) and group I (p < 0.003). There was a significant reduction of 65% and 71% in intima/media layer area ratio in group II vs. control group and group I, respectively. Conclusion Pretreatment with rosiglitazone in hypercholesterolemic rabbits submitted to vascular injury significantly reduces neointimal formation.

Abstract
BACKGROUND Drug-eluting stents reduce the risk of restenosis after percutaneous coronary intervention (PCI) but may pose a risk of thrombosis. Cilostazol, an oral antiplatelet agent with pleiotropic effects including inhibition of neointimal hyperplasia, could hold the promise of preventing both restenosis and thrombosis. We systematically reviewed randomized clinical trials (RCTs) on the angiographic and clinical impact of cilostazol after PCI. METHODS We searched RCT in BioMedCentral, CENTRAL, clinicaltrials.gov, EMBASE, and PubMed (November 2007). Coprimary end points were binary angiographic restenosis and repeat revascularization, abstracted and pooled by means of random-effect relative risks (RRs). Small study/publication bias was appraised with multiple methods. RESULTS A total of 23 RCTs were included (5428 patients), with median follow-up of 6 months. Pooled analysis showed that cilostazol was associated with statistically significant reductions in binary angiographic restenosis (RR = 0.60 [0.49-0.73], P < .001) and repeat revascularization (RR = 0.69 [0.55-0.86], P = .001). Cilostazol appeared also safe, with no significant increase in the risk of stent thrombosis (RR = 1.35 [0.71-2.57], P = .36) or bleeding (RR = 0.71 [0.43-1.16], P = .17). However, small study bias was evident for both binary restenosis (P < .001) and repeat revascularization (P < .001), suggesting that at least part of the apparent benefits of cilostazol could be due to this type of confounding effect. CONCLUSIONS Cilostazol appears effective and safe in reducing the risk of restenosis and repeat revascularization after PCI, but available evidence is limited by small study effects. Awaiting larger RCTs, this inexpensive treatment can be envisaged in selected patients in which drug-eluting stents are contraindicated or when there is a need for neointimal hyperplasia inhibition.

Abstract
BACKGROUND Recent experimental studies have demonstrated that thiazolidinediones (TZDs) therapy inhibits proliferation and migration of vascular smooth muscle cells, accelerates endothelium reparation and attenuates neointimal hyperplasia. It implies that TZDs therapy may have beneficial effects on in-stent restenosis (ISR). Several small-sample clinical trials have evaluated the effect of TZDs therapy on ISR, however, the results were inconsistent across trials. METHODS AND RESULTS We performed a meta-analysis of all relevant randomized controlled trials to evaluate the effect of TZDs therapy on in-stent restenosis in patients undergoing coronary stenting. Eight trials involving 366 patients were included in this study. TZDs therapy was associated with a significant reduction in the risk of ISR in both diabetic (RR 0.37, 95% CI 0.23-0.59; P<0.0001) and non-diabetic patients (RR 0.16, 95% CI 0.05-0.45; P=0.0006). TZDs therapy was associated with a significant reduction in late lumen loss (WMD -0.54 mm, 95% CI -0.87 mm, -0.22 mm; P=0.001), percent diameter stenosis (WMD -15.7%, 95% CI -19.4%, -12.0%; P<0.00001), neointimal area/volume (SMD -0.76, 95% CI -1.13, -0.39; P<0.0001) and target lesion revascularization (RR 0.32, 95% CI 0.18-0.57; P=0.0001). CONCLUSIONS Our study suggests that TZDs therapy is an effective strategy in preventing ISR in both diabetic and non-diabetic patients undergoing coronary stenting. More studies, especially large multi-centre RCTs, are still warranted to further clarify the anti-restenotic effect of TZDs therapy.

Abstract
BACKGROUND The overall clinical benefit of thiazolidinediones (TZDs) as a treatment for hyperglycaemia can be difficult to assess because of the risk of congestive heart failure due to TZD-related fluid retention. Since prediabetic and diabetic patients are at high cardiovascular risk, the outcome and natural history of such risks need to be better understood. We aimed to examine the risk of congestive heart failure and of cardiac death in patients given TZDs. METHODS We used a search strategy to identify 3048 studies. 3041 were excluded, and we did a systematic review and meta-analysis of the seven remaining randomised double-blind clinical trials of drug-related congestive heart failure in patients given TZDs (either rosiglitazone or pioglitazone). We calculated pooled random-effects estimates of the risk ratios for development of congestive heart failure in patients given TZDs compared with controls. The main outcome measures were development of congestive heart failure and the risk of cardiovascular death. FINDINGS 360 of 20 191 patients who had either prediabetes or type 2 diabetes had congestive heart failure events (214 with TZDs and 146 with comparators). Results showed no heterogeneity of effects across studies (I2=22.8%; p for interaction=0.26), which indicated a class effect for TZDs. Compared with controls, patients given TZDs had increased risk for development of congestive heart failure across a wide background of cardiac risk (relative risk [RR] 1.72, 95% CI 1.21-2.42, p=0.002). By contrast, the risk of cardiovascular death was not increased with either of the two TZDs (0.93, 0.67-1.29, p=0.68). INTERPRETATION Congestive heart failure in patients given TZDs might not carry the risk that is usually associated with congestive heart failure which is caused by progressive systolic or diastolic dysfunction of the left ventricle. Longer follow-up and better characterisation of such patients is needed to determine the effect of TZDs on overall cardiovascular outcome.

Abstract
Pioglitazone, a member of the PPAR-gamma agonist drug family, has been demonstrated to improve both metabolic and vascular insulin resistance when applied to patients with Type 2 diabetes mellitus. The drug is well tolerated with fluid retention and weight gain being the most frequently described side effects. The observed effects (e.g., improvements in glucose and lipid metabolism, improvements of endothelial function and microcirculation, reduction of surrogate markers of atherosclerosis and inflammation and an improvement in hypertension) have made pioglitazone one of the frequently prescribed antidiabetic drugs in the US and Europe. Several trials have shown its potency to reduce carotid intima-media thickness, and outcome studies with pioglitazone have shown its potential to delay the progression of Type 2 diabetes and atherosclerosis and even reduce cardiovascular mortality. The purpose of this review is to provide an overview about recently published clinical results with pioglitazone. They underline the value of this drug when used alone or in combination with other antidiabetic drugs for a successful management of Type 2 diabetes mellitus.
