Role of dipeptidyl peptidase 4 inhibitors in the new era of antidiabetic treatment. World J Diabetes 2022; 13:85-96. [PMID: 35211246 PMCID: PMC8855136 DOI: 10.4239/wjd.v13.i2.85] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 07/29/2021] [Accepted: 01/26/2022] [Indexed: 02/06/2023] Open
Abstract
The last few years important changes have occurred in the field of diabetes treatment. The priority in the therapy of patients with diabetes is not glycemic control per se rather an overall management of risk factors, while individualization of glycemic target is suggested. Furthermore, regulatory authorities now require evidence of cardiovascular (CV) safety in order to approve new antidiabetic agents. The most novel drug classes, i.e., sodium-glucose transporter 2 inhibitors (SGLT2-i) and some glucagon-like peptide-1 receptor agonists (GLP-1 RA), have been demonstrated to reduce major adverse CV events and, thus, have a prominent position in the therapeutic algorithm of hyperglycemia. In this context, the role of previously used hypoglycemic agents, including dipeptidyl peptidase 4 (DPP-4) inhibitors, has been modified. DPP-4 inhibitors have a favorable safety profile, do not cause hypoglycemia or weight gain and do not require dose uptitration. Furthermore, they can be administered in patients with chronic kidney disease after dose modification and elderly patients with diabetes. Still, though, they have been undermined to a third line therapeutic choice as they have not been shown to reduce CV events as is the case with SGLT2-i and GLP-1 RA. Overall, DPP-4 inhibitors appear to have a place in the management of patients with diabetes as a safe class of oral glucose lowering agents with great experience in their use.

Is there a role of lipid-lowering therapies in the management of fatty liver disease? World J Hepatol 2022; 14:119-139. [PMID: 35126843 PMCID: PMC8790403 DOI: 10.4254/wjh.v14.i1.119] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 08/30/2021] [Accepted: 12/08/2021] [Indexed: 02/06/2023] Open
Abstract
Atherogenic dyslipidemia is characterized by increased triglyceride-rich lipoproteins and low high-density lipoprotein cholesterol concentrations. It is highly prevalent in non-alcoholic fatty liver disease (NAFLD) and contributes to the increased cardiovascular risk associated with this condition. Alongside insulin resistance it plays an important pathogenetic role in NAFLD/non-alcoholic steatohepatitis (NASH) development and progression. It has been shown that cholesterol-lowering reduces cardiovascular risk more in NAFLD vs non-NAFLD high-risk individuals. This evidence highlights the importance of effective lipid modulation in NAFLD. In this narrative review the effects of the most commonly used lipid-lowering therapies on liver outcomes alongside their therapeutic implications in NAFLD/NASH are critically discussed. Preclinical and clinical evidence suggests that statins reduce hepatic steatosis, inflammation and fibrosis in patients with NAFLD/NASH. Most data are derived from observational and small prospective clinical studies using changes in liver enzyme activities, steatosis/fibrosis scores, and imaging evidence of steatosis as surrogates. Also, relevant histologic benefits were noted in small biopsy studies. Atorvastatin and rosuvastatin showed greater benefits, whereas data for other statins are scarce and sometimes conflicting. Similar studies to those of statins showed efficacy of ezetimibe against hepatic steatosis. However, no significant anti-inflammatory and anti-fibrotic actions of ezetimibe have been shown. Preclinical studies showed that fibrates through peroxisome proliferator-activated receptor (PPAR)α activation may have a role in NAFLD prevention and management. Nevertheless, no relevant benefits have been noted in human studies. Species-related differences in PPARα expression and its activation responsiveness may help explain this discrepancy. Omega-3 fatty acids reduced hepatic steatosis in numerous heterogeneous studies, but their benefits on hepatic inflammation and fibrosis have not been established. Promising preliminary data for the highly purified eicosapentaenoic acid require further confirmation. Observational studies suggest that proprotein convertase subtilisin/kexin9 inhibitors may also have a role in the management of NAFLD, though this needs to be established by future prospective studies.

Early Investigational and Experimental Therapeutics for the Treatment of Hypertriglyceridemia. J Cardiovasc Dev Dis 2022; 9:jcdd9020042. [PMID: 35200696 PMCID: PMC8874974 DOI: 10.3390/jcdd9020042] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 01/01/2022] [Accepted: 01/20/2022] [Indexed: 02/04/2023] Open
Abstract
Hypertriglyceridemia has been identified as a risk factor for cardiovascular disease and acute pancreatitis. To date, there are only few drug classes targeting triglyceride levels such as fibrates and ω-3 fatty acids. These agents are at times insufficient to address very high triglycerides and the residual cardiovascular risk in patients with mixed dyslipidemia. To address this unmet clinical need, novel triglyceride-lowering agents have been in different phases of early clinical development. In this review, the latest and experimental therapies for the management of hypertriglyceridemia are presented. Specifically, ongoing trials evaluating novel apolipoprotein C-III inhibitors, ω-3 fatty acids, as well as fibroblast growth 21 analogues are discussed.

Abstract
Advances in several fields of cardiovascular (CV) medicine have produced new treatments (e.g. to treat dyslipidaemia) that have proven efficacy in terms of reducing deaths and providing a better quality of life. However, the burden of CV disease (CVD) remains high. Thus, there is a need to search for new treatment targets. Lipoprotein (a) [Lp(a)] has emerged as a potential novel target since there is evidence that it contributes to CVD events. In this narrative review, we present the current evidence of the potential causal relationship between Lp(a) and CVD and discuss the likely magnitude of Lp(a) lowering required to produce a clinical benefit. We also consider current and investigational treatments targeting Lp(a), along with the potential cost of these interventions.

Investigating the lowest threshold of vascular benefits from LDL cholesterol lowering with a PCSK9 mAb inhibitor (alirocumab) in healthy volunteers - a mechanistic physiological study (INTENSITY-LOW): protocol and study rationale. J Drug Assess 2019; 8:167-174. [PMID: 31692938 PMCID: PMC6818119 DOI: 10.1080/21556660.2019.1677673] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2019] [Accepted: 09/25/2019] [Indexed: 11/15/2022] Open
Abstract
Objective: Whether reducing low density lipoprotein cholesterol (LDL-C) is associated with cardiovascular benefits in low risk normocholesterolaemic subjects is unknown. The INTENSITY LOW [Investigating the lowest threshold of vascular benefits from LDL-cholesterol lowering with a PCSK9 mAb inhibitor (alirocumab) in healthy volunteers] study aims to assess whether lowering LDL-C by alirocumab monotherapy can improve endothelial-dependent vascular function compared with placebo (primary objective) in low-risk normocholesterolaemic healthy individuals. Changes in endothelial-dependent or endothelial-independent vascular function, arterial stiffness and biomarkers of systemic inflammation by alirocumab, atorvastatin or their combination are secondary objectives. Study design and methods: This is a single-center, randomized, two-period, single-blind, placebo-controlled clinical trial. The study was registered on clinicaltrials.gov (N03273972). It will include 30 healthy low-risk subjects with LDL-C < 4.1 mmol/l. After passing the screening visit (Visit 1), eligible participants will be randomized 1:1 to either subcutaneous alirocumab 150 mg or placebo. These will be administered as single doses in 2 visits 14 days apart (Visits 2 and 3). Atorvastatin 20 mg once nightly will be prescribed for 14 days at Visit 3 in both groups through to Visit 4. At baseline (Visit 2) and during all post-dose visits (Visits 3–4), endothelial function will be assessed using venous occlusion plethysmography. Specifically, changes in forearm blood flow responses to intra-arterial infusions of acetylcholine, sodium nitroprusside and L-NG-monomethyl-arginine acetate will be assessed as surrogates of endothelial-dependent and -independent vasodilatation. Additionally, arterial stiffness and carotid intima-media thickness will be evaluated at the same timepoints. The above-mentioned changes will be correlated with changes in lipid and systemic inflammation biomarkers.

Prevalence, Identification, and Scouting for Familial Hypercholesterolaemia Including Registries. Curr Pharm Des 2019; 24:3605-3615. [PMID: 30306861 DOI: 10.2174/1381612824666181009103440] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2018] [Revised: 09/25/2018] [Accepted: 10/02/2018] [Indexed: 11/22/2022]
Abstract
Background:
Familial Hypercholesterolaemia (FH) is the most common metabolic genetic disorder,
with around 13 million people worldwide having the disease. However, FH is globally underdiagnosed and undertreated,
while the vast majority of those treated do not achieve treatment goals.
Objective:
This review aims to clarify how to identify patients with FH.
Methods:
We performed a comprehensive search of the literature to identify available data.
Results:
Patients with FH are at high risk for cardiovascular events and death at an early age. Therefore, prompt
detection of individuals with FH is of pivotal importance in order to implement appropriate preventive measures
at a young age. Patient registries are a powerful tool for recording and monitoring a disease and encouraging
clinical practices, subsequently improving outcomes and reducing healthcare costs. National FH registries are
successfully applied in several countries (e.g. Spain, Denmark, UK, USA and the Netherlands). Importantly, in
the last few years, the European Atherosclerosis Society (EAS) launched a global FH network aiming to collect
data from specialized FH centres from different countries and establish a worldwide, standardised registry of
patients with FH.
Conclusion:
It appears that the establishment and proper function of such registries will improve FH diagnosis,
as well as preventive measures and management of FH patients.

Statins and mortality: the untold story. Br J Clin Pharmacol 2017; 83:938-941.

Abstract
Statins are first-line evidence-based drugs for the management of dyslipidaemias and to reduce the risk of cardiovascular events. However, statin clinical trials have shown marginally significant benefits on mortality, especially in the primary prevention setting. A major limitation of those trials is their relatively short follow-up. A reduced number of fatal events within a 5-year follow-up make mortality benefits unlikely to arise. This is particularly relevant for the primary prevention trials, where the risk of cardiovascular death is low. The short follow-up is a limitation for safety assessments too. However, extended major statin trials failed to detect any major safety concerns. Safety and efficacy assessments are even more complicated considering the differences of cardiovascular risk status in primary prevention individuals, and also given some potential ethnic and inter-individual genetic variations in response to statin treatment. Considerable evidence suggests a favourable risk-benefit balance for statin treatment. It can be assumed that statins reduce mortality in the long term by preventing cardiovascular events with complications that reduce lifespan. Unfortunately, this hypothesis cannot be proven as there is no current ethical basis on designing long-term placebo-controlled statin trials. Nevertheless, by effectively reducing disabilities related to cardiovascular events, statins have major benefits for public health. Therefore, clinicians should not withhold statin treatment awaiting proof of mortality benefits, as this may remain an 'untold story'.

Abstract
Objective. To evaluate the influence of clinical, biochemical and genetic markers on the response to antihypertensive treatment in patients with essential hypertension and the metabolic syndrome (MetS). Methods. Measurements of anthropometric indices, blood pressure (BP), and metabolic parameters were obtained from the medical records of 132 (77 women) newly diagnosed, untreated hypertensive patients. Renin-angiotensin-aldosterone system (RAAS) genes polymorphisms (including ACE I/D, angiotensinogen M235T, angiotensin II type 1 receptor [AT1-receptor] A1166C) were determined. Response to treatment was defined as BP less than 140/90 mmHg. Results. Patients with MetS (n=60) had higher systolic BP and pulse pressure and a more atherogenic lipid profile than patients without MetS.The frequencies of the ACE and the AT1-receptor gene polymorphisms were similar between patients with and without MetS. Response to treatment was positively associated with pulse pressure, and the presence of the C allele as well as the AC genotype of the AT1-receptor gene and inversely with age after adjustment for confounding factors. Conclusions. RAAS genes distribution does not differ between hypertensive patients with and without the MetS. Higher baseline pulse pressure levels, the presence of the C allele and/or the AC genotype may be in favour of a better response to structured antihypertensive treatment in patients with MetS. However, these findings need to be evaluated in future studies.

Abstract
Concerns have been raised because of observations of proteinuria associated with rosuvastatin treatment. In this open-label study, a potential dose-dependent effect was investigated of rosuvastatin on urinary protein excretion and renal function parameters in 90 hyperlipidemic patients randomly assigned to rosuvastatin 10 mg/day (n = 45) or 20 mg/day (n = 45). Urinary samples were collected from patients and 40 age- and gender-matched controls to determine electrolyte, uric acid, creatinine, and protein (total, albumin, IgG, and α1-microglobulin) levels at baseline and after 12 weeks. A dose-dependent increase in the excretion of α1-microglobulin (17.6% in rosuvastatin 10 vs 34.9% in rosuvastatin, 20 mg/day; P = .03 for the comparison between groups) was observed. A trend toward an increase in the estimated glomerular filtration rate was noted in only patients receiving 20 mg/day of rosuvastatin. These findings indicate that rosuvastatin treatment increases the urinary excretion of α1-microglobulin urinary excretion in a dose-dependent manner without adversely affecting renal function.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) might influence the metabolism of cholesterol and statins in the liver. AIM The impact of PPIs on low-density lipoprotein cholesterol (LDL-C) levels in statin-treated patients. METHODS Retrospective observational study including consecutive statin-treated individuals followed for ≥3 years in a university hospital lipid clinic. Demographic characteristics as well as clinical and laboratory data were recorded at baseline and the most recent visit. High, moderate and low-intensity statin therapy was defined according to the expected LDL-C reduction (≥50%, 30-50%, and <30%, respectively). We compared the LDL-C reduction in subjects receiving statin + PPI with those on statin alone and assessed the overall effect of PPI administration on LDL-C lowering. RESULTS Of 648 statin-treated subjects, 7% were also taking a PPI. There was no difference between PPI vs. non-PPI group regarding baseline characteristics and intensity of lipid-lowering therapy. Stepwise linear regression analysis showed that PPI use was significantly associated with LDL-C reduction (b =0.104, p =0.005) along with baseline LDL-C levels (b =0.482, p <0.001), treatment with ezetimibe (b =0.198, p <0.001), presence of diabetes (b =0.168, p <0.001), compliance with treatment (b =0.205, p <0.001), intensity of statin treatment (b =0.101, p =0.005) and cardiovascular risk (b =0.082, p =0.049). Subjects receiving statin + PPI had a higher LDL-C reduction by 6.4% compared with those taking a statin alone (fully adjusted p =0.005). CONCLUSIONS PPIs may modestly boost the statin-mediated LDL-C reduction. This effect should be confirmed by prospective clinical studies. Hippokratia 2015; 19 (4): 332-337.

Abstract
OBJECTIVES To investigate the effect of benchmarking on the quality of type 2 diabetes (T2DM) care in Greece. METHODS The OPTIMISE (Optimal Type 2 Diabetes Management Including Benchmarking and Standard Treatment) study [ClinicalTrials.gov identifier: NCT00681850] was an international multicenter, prospective cohort study. It included physicians randomized 3:1 to either receive benchmarking for glycated hemoglobin (HbA1c), systolic blood pressure (SBP) and low-density lipoprotein cholesterol (LDL-C) treatment targets (benchmarking group) or not (control group). The proportions of patients achieving the targets of the above-mentioned parameters were compared between groups after 12 months of treatment. Also, the proportions of patients achieving those targets at 12 months were compared with baseline in the benchmarking group. RESULTS In the Greek region, the OPTIMISE study included 797 adults with T2DM (570 in the benchmarking group). At month 12 the proportion of patients within the predefined targets for SBP and LDL-C was greater in the benchmarking compared with the control group (50.6 versus 35.8%, and 45.3 versus 36.1%, respectively). However, these differences were not statistically significant. No difference between groups was noted in the percentage of patients achieving the predefined target for HbA1c. At month 12 the increase in the percentage of patients achieving all three targets was greater in the benchmarking (5.9-15.0%) than in the control group (2.7-8.1%). In the benchmarking group more patients were on target regarding SBP (50.6% versus 29.8%), LDL-C (45.3% versus 31.3%) and HbA1c (63.8% versus 51.2%) at 12 months compared with baseline (p < 0.001 for all comparisons). CONCLUSION Benchmarking may comprise a promising tool for improving the quality of T2DM care. Nevertheless, target achievement rates of each, and of all three, quality indicators were suboptimal, indicating there are still unmet needs in the management of T2DM.

Abstract
OBJECTIVE There is a paucity of data regarding the attainment of lipid-lowering treatment goals according to the recent American College of Cardiology/American Heart Association (ACC/AHA) guidelines. The aim of the present study was to assess how applicable these 2013 recommendations are in the setting of an Outpatient University Hospital Lipid Clinic. METHODS This was a retrospective (from 1999 to 2013) observational study including 1000 consecutive adults treated for hyperlipidemia and followed up for ≥3 years. Comparisons for the applicability of current European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) and recent ACC/AHA guidelines were performed. RESULTS Achievement rates of low density lipoprotein cholesterol (LDL-C) targets set by ESC/EAS were 21%, 44% and 62% among patients at very high, high and moderate cardiovascular risk, respectively, receiving statin monotherapy. Among individuals on high-intensity statins only 47% achieved the anticipated ≥50% LDL-C reduction, i.e. the ACC/AHA target. The corresponding rate was significantly greater among those on statin + ezetimibe (76%, p < 0.05). Likewise, higher rates of LDL-C target attainment according to ESC/EAS guidelines were observed in patients on statin + ezetimibe compared with statin monotherapy (37, 50 and 71% for the three risk groups, p < 0.05 for the very high risk group). CONCLUSION The application of the ACC/AHA guidelines may be associated with undertreatment of high risk patients due to suboptimal LDL-C response to high-intensity statins in clinical practice. Adding ezetimibe substantially increases the rate of the ESC/EAS LDL-C target achievement together with the rate of LDL-C lowering response suggested by the ACC/AHA.

Abstract
Background: Prediabetes substantially increases cardiovascular risk. We examined the effect of rosuvastatin on the quantity and quality of low-density lipoprotein cholesterol (LDL-C) in patients with dyslipidemia having impaired fasting glucose (IFG) compared to normoglycemic patients with dyslipidemia. Methods: This was a prospective observational study including patients with dyslipidemia and IFG (IFG group, n = 49) matched with normoglycemic patients with dyslipidemia (control group, n = 64). Study participants, following dietary intervention, were prescribed rosuvastatin 10 or 20 mg/d to achieve LDL-C goals. Baseline as well as 24 weeks posttreatment changes in the serum lipid profile were evaluated. Moreover, analysis of the LDL subfraction profile was conducted using a polyacrylamide tube gel electrophoresis method. Results: Similar effects were observed in lipid profile in both treatment groups. Patients with IFG experienced a greater decrease in the cholesterol concentration of small dense LDL particles (−65.7%, P < .001 vs baseline) compared to controls (−38.5%, P < .001 vs baseline; P = .018 vs patients with IFG). There was no significant difference in the changes of cholesterol concentration of large and buoyant LDL particles in the IFG group when compared to the control group. A greater increase in the mean LDL particle size (+1.5%, P < .001 vs baseline) was noted in the IFG group compared to the control group at 24 weeks (+0.4%, P = .028 vs baseline; P = .008 vs IFG group). Conclusion: Targeting dyslipidemia with rosuvastatin was associated with more favorable changes in the LDL subfraction profile in patients with IFG compared to normoglycemic ones.

Abstract
This was a retrospective study that assessed achievement of lipid-lowering treatment targets in the setting of a University Hospital Lipid Clinic. Low-density lipoprotein cholesterol (LDL-C) goal attainment according to National Cholesterol Education Program-Adult Treatment Panel III (NCEP ATP III) and European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) guidelines was recorded in 1000 consecutive adult patients followed for ≥3 years (mean 8 years). The LDL-C targets according to the NCEP ATP III were attained by 66% and 86% of patients with "very high" (n = 477) and "high" (n = 408) cardiovascular risk, respectively. Fewer patients were within LDL-C goals according to the ESC/EAS guidelines: 25% and 42%. Overall, 92% of the patients were on statins: 67% were on statin monotherapy, while 33% were on combinations with ezetimibe (25%), ω-3 fatty acids (5%), fibrates (4%), or colesevelam (2%). Even in a specialist lipid clinic, a large proportion of patients are not at goal according to the recent ESC/EAS guidelines.

Abstract
Patients with type 2 diabetes mellitus (T2DM) frequently exhibit macrovascular complications of atherosclerotic cardiovascular (CV) disease. High density lipoproteins (HDL) are protective against atherosclerosis. Low levels of HDL cholesterol (HDL-C) independently contribute to CV risk. Patients with T2DM not only exhibit low HDL-C, but also dysfunctional HDL. Furthermore, low concentration of HDL may increase the risk for the development of T2DM through a decreased β cell survival and secretory function. In this paper, we discuss emerging concepts in the relationship of T2DM with HDL.

[PMID: 24567804 PMCID: PMC3932430 DOI: 10.4239/wjd.v5.i1.76] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2013] [Revised: 10/31/2013] [Accepted: 01/14/2014] [Indexed: 02/05/2023] Open
Abstract
AIM: To describe baseline data of the optimal type 2 diabetes management including benchmarking and standard treatment (OPTIMISE) study in Greece.
METHODS: “Benchmarking” is the process of receiving feedback comparing one’s performance with that of others. The OPTIMISE (NCT00681850) study is a multinational, multicenter study assessing, at a primary care level, whether using “benchmarking” can help to improve the quality of patient care, compared with a set of guideline-based reference values (“non-benchmarking”). In the Greek region, 797 outpatients (457 men, mean age 63.8 years) with type 2 diabetes were enrolled by 84 office-based physicians. Baseline characteristics of this population are presented.
RESULTS: Hypertension was the most prevalent concomitant disorder (77.3%) and coronary heart disease was the most frequent macrovascular complication of diabetes (23.8%). Most patients were overweight or obese (body mass index 29.6 ± 5 kg/m2), exhibiting mostly abdominal obesity (waist circumference 102.6 ± 13.6 cm). Biguanides were the most prevalent prescribed drugs for the management of diabetes (70.1% of all prescriptions), whereas statins (93.5% of all prescriptions) and angiotensin receptor blockers (55.8% of all prescriptions) were the most prevalent prescribed drugs for hyperlipidemia and hypertension, respectively. Only 37.4% of patients were on aspirin. Despite treatment, pre-defined targets for fasting plasma glucose (< 110 mg/dL), glycated hemoglobin (< 7%), systolic blood pressure (< 130 mmHg and < 125 mmHg for patients with proteinuria) and low density lipoprotein cholesterol levels (< 100 mg/dL and < 70 mg/dL for patients with coronary heart disease) were reached in a relatively small proportion of patients (29%, 53%, 27% and 31%, respectively). In a Greek population with type 2 diabetes, the control of glycemia or concomitant disorders which increase cardiovascular risk remains poor.
CONCLUSION: Despite relevant treatment, there is a poor control of diabetes, hypertension and hyperlipidemia in Greek outpatients with type 2 diabetes.

Abstract
After the withdrawal of troglitazone and rosiglitazone, pioglitazone remains the sole thiazolidinedione (TZD) still available. Pioglitazone is efficacious in improving glycemic control and reduce the risk of cardiovascular events. Although generally well-tolerated, pioglitazone was withdrawn by some national medicines agencies (e.g. in France and Germany) due to reports of increased incidence of bladder cancer. In this article, we review the literature on the association between pioglitazone and cancer in several sites, including the bladder. Pioglitazone, like other TZDs, increased differentiation, inhibited growth and proliferation, while provoked apoptosis in various cancer cells, including bladder cancer, in vitro and in vivo. However, a rat-specific carcinogenic effect of pioglitazone on the bladder was noted in vivo. Clinical data for the risk of various cancer sites mostly come from observational studies and are subject to bias. An increased risk for bladder cancer by pioglitazone was suggested by retrospective analyses. This risk was associated with the time of exposure and the age, by identifying 24 months and 65 years, respectively, as time 'thresholds' above which this risk becomes relevant. In contrast, no increased risk for bladder cancer was associated with pioglitazone in randomized clinical trials. Pioglitazone was associated with increased incidence of melanoma and non-Hodgkin lymphoma and decreased risk of renal cancer in one cohort study. These findings need to be re-evaluated on a prospective basis. There is no convincing evidence that pioglitazone increases or decreases the risk of cancer in other sites. In contrast, it was suggested that this drug may be useful either in the treatment of cancer complications or as an adjunct to chemotherapeutic agents. Considering the clinical benefit from the use of pioglitazone it is reasonable to wait until data from ongoing clinical trials are available before reaching definitive conclusions. Nevertheless, the potential for increased risk of bladder cancer should be taken into consideration, especially in the presence of other risk factors for bladder carcinogenesis (e.g. smoking).

Abstract
INTRODUCTION The aim of this study was to investigate the effect of the Mediterranean diet on the likelihood of having a non-fatal cardiovascular outcome, taking into account anxiety and depression status. METHODS This was a case-control study with individual matching by age and sex. During 2009-2010, 1000 participants were enrolled; 250 were consecutive patients with a first acute coronary syndrome (ACS), 250 were consecutive patients with a first ischemic stroke, and 500 were population-based control subjects, one-for-one matched to the patients by age and sex. Among other characteristics, adherence to the Mediterranean diet was assessed by the MedDietScore, anxiety was assessed with the Spielberger State-Trait Anxiety Inventory form Y-2, while depressive symptomatology was evaluated by the Zung Depression Rating Scale. RESULTS Higher adherence to the Mediterranean diet was associated with a lower likelihood of ACS and ischemic stroke, even after adjusting for anxiety or depression (ACS: OR=0.92, 95%CI 0.87-0.98 and 0.93, 0.88-0.98, respectively; ischemic stroke: 0.91, 0.84-0.98 and 0.90, 0.83-0.97, respectively). For both ACS and stroke patients, anxiety and depression were associated with a higher likelihood of ACS and stroke. When stratifying for depression or anxiety status, the Mediterranean diet remained a significantly protective factor only for people with low levels of depression and anxiety for ACS, and only for people with low levels of anxiety, as far as stroke was concerned. CONCLUSION Anxiety and depression seem to play a mediating role in the protective relationship between adherence to the Mediterranean diet and the likelihood of developing cardiovascular events.

Current role of fenofibrate in the prevention and management of non-alcoholic fatty liver disease. World J Hepatol 2013; 5:470-478.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a common health problem with a high mortality burden due to its liver- and vascular-specific complications. It is associated with obesity, high-fat diet as well as with type 2 diabetes mellitus (T2DM) and metabolic syndrome (MetS). Impaired hepatic fatty acid (FA) turnover together with insulin resistance are key players in NAFLD pathogenesis. Peroxisome proliferator-activated receptors (PPARs) are involved in lipid and glucose metabolic pathways. The novel concept is that the activation of the PPARα subunit may protect from liver steatosis. Fenofibrate, by activating PPARα, effectively improves the atherogenic lipid profile associated with T2DM and MetS. Experimental evidence suggested various protective effects of the drug against liver steatosis. Namely, fenofibrate-related PPARα activation may enhance the expression of genes promoting hepatic FA β-oxidation. Furthermore, fenofibrate reduces hepatic insulin resistance. It also inhibits the expression of inflammatory mediators involved in non-alcoholic steatohepatitis pathogenesis. These include tumor necrosis factor-α, intercellular cell adhesion molecule-1, vascular cell adhesion molecule-1 and monocyte chemoattractant protein-1. Consequently, fenofibrate can limit hepatic macrophage infiltration. Other liver-protective effects include decreased oxidative stress and improved liver microvasculature function. Experimental studies showed that fenofibrate can limit liver steatosis associated with high-fat diet, T2DM and obesity-related insulin resistance. Few studies showed that these benefits are also relevant even in the clinical setting. However, these have certain limitations. Namely, these were uncontrolled, their sample size was small, fenofibrate was used as a part of multifactorial approach, while histological data were absent. In this context, there is a need for large prospective studies, including proper control groups and full assessment of liver histology.

Abstract
BACKGROUND Fenofibrate has been used for the management of atherogenic dyslipidaemia for many years. Reports of fenofibrate-associated increases in serum creatinine (SCr) levels raised concerns regarding deleterious effects on renal function. DESIGN In this narrative review, we discuss available literature on the effect of fenofibrate on the kidney. RESULTS Most clinical studies showed a rapid (within weeks) raising effect of fenofibrate on SCr levels. This was often accompanied by declined estimated glomerular filtration rate. Risk predictors of this adverse effect might include increased age, impaired renal function and high-dose treatment. Also, the concomitant use of medications affecting renal hemodynamics (e.g. angiotensin-converting enzyme-inhibitors (ACEi) and angiotensin receptor blockers) may predispose to fenofibrate-associated increased SCr levels. Interestingly, SCr increases by fenofibrate were transient and reversible even without treatment discontinuation. Furthermore, fenofibrate was associated with a slower progression of renal function impairment and albuminuria in a long-term basis. Also, fenofibrate might be protective against pathological changes in diabetic nephropathy and hypertensive glomerulosclerosis. In this context, it is uncertain whether fenofibrate-associated increase in SCr levels mirrors true renal function deterioration. Several theories have been expressed. The most dominant one involved the inhibition of renal vasodilatory prostaglandins reducing renal plasma flow and glomerular pressure. Increased creatinine secretion or reduced creatinine clearance by fenofibrate was also suggested. These hypotheses should be settled by further studies. CONCLUSIONS Fenofibrate may not be a nephrotoxic drug. However, a close monitoring of SCr levels is relevant especially in high-risk patients. Increases in SCr levels ≥30% can impose treatment discontinuation.

Abstract
The renoprotective effect of statins has been recently disputed because of observations of proteinuria associated with rosuvastatin treatment, the newest drug of the class. Statin-induced proteinuria findings were mainly based on crudely quantitative dipstick assays. The authors quantitatively evaluated the effect of rosuvastatin at the recommended starting dose of 10 mg/d, on urine protein excretion in patients with primary dyslipidemia. Serum lipid and nonlipid parameters as well as urinary electrolyte, creatinine, and protein (total, albumin, immunoglobulin G, and alpha-1 microglobulin) levels were measured in 40 patients treated with rosuvastatin and 30 controls at baseline and after 12 weeks. The protein-to-creatinine ratios were used to assess urinary protein excretion. Rosuvastatin improved the lipid profile, produced no deterioration of kidney function, but induced a small but significant increase in the excretion of alpha-1 microglobulin (by 16%, P < .05) indicating that statin-related proteinuria involves low-molecular-weight proteins and is of proximal tubular origin.

Abstract
BACKGROUND AND AIMS Although significant evidence exists regarding the role of specific foods and dietary patterns on the development of cardiovascular disease, the influence of eating practices has not been thoroughly examined and understood. The aim of the present work was to evaluate the independent role of eating practices on the likelihood of developing an acute coronary syndrome (ACS) or ischemic stroke. METHODS AND RESULTS During 2009-2010, 1000 participants were enrolled; 250 were consecutive patients with a first ACS, 250 were consecutive patients with a first ischemic stroke and 500 were population-based control subjects (250 age-sex matched one-for-one with ACS patients, and 250 age-sex matched one-for-one with stroke patients). Eating practices were evaluated using a special questionnaire. Socio-demographic, clinical, psychological, dietary and other lifestyle characteristics were also measured. After controlling for potential confounding factors, each 20 min prolongation of dinner-to-sleep time was associated with 10% lower likelihood of ischemic stroke (95%CI: 0.83-0.98). Furthermore, eating practices related to stress (i.e., eating while being stressed, eating while working at the same time, skipping a meal due to work obligations) were associated with higher likelihood of having an ACS. Finally, eating while watching television was associated with lower likelihood of having an ACS (OR: 0.46, 95%CI: 0.27-0.78) or stroke event (OR: 0.42, 95%CI: 0.23-0.77). CONCLUSION Results of this work, present novel information, indicating the significance of eating practices, in addition to dietary patterns, regarding the development of coronary heart disease and stroke, and could be used in the primary prevention of CVD.

Abstract
CONTEXT Considerable controversy exists regarding the association of omega-3 polyunsaturated fatty acids (PUFAs) and major cardiovascular end points. OBJECTIVE To assess the role of omega-3 supplementation on major cardiovascular outcomes. DATA SOURCES MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials through August 2012. STUDY SELECTION Randomized clinical trials evaluating the effect of omega-3 on all-cause mortality, cardiac death, sudden death, myocardial infarction, and stroke. DATA EXTRACTION Descriptive and quantitative information was extracted; absolute and relative risk (RR) estimates were synthesized under a random-effects model. Heterogeneity was assessed using the Q statistic and I2. Subgroup analyses were performed for the presence of blinding, the prevention settings, and patients with implantable cardioverter-defibrillators, and meta-regression analyses were performed for the omega-3 dose. A statistical significance threshold of .0063 was assumed after adjustment for multiple comparisons. DATA SYNTHESIS Of the 3635 citations retrieved, 20 studies of 68,680 patients were included, reporting 7044 deaths, 3993 cardiac deaths, 1150 sudden deaths, 1837 myocardial infarctions, and 1490 strokes. No statistically significant association was observed with all-cause mortality (RR, 0.96; 95% CI, 0.91 to 1.02; risk reduction [RD] -0.004, 95% CI, -0.01 to 0.02), cardiac death (RR, 0.91; 95% CI, 0.85 to 0.98; RD, -0.01; 95% CI, -0.02 to 0.00), sudden death (RR, 0.87; 95% CI, 0.75 to 1.01; RD, -0.003; 95% CI, -0.012 to 0.006), myocardial infarction (RR, 0.89; 95% CI, 0.76 to 1.04; RD, -0.002; 95% CI, -0.007 to 0.002), and stroke (RR, 1.05; 95% CI, 0.93 to 1.18; RD, 0.001; 95% CI, -0.002 to 0.004) when all supplement studies were considered. CONCLUSION Overall, omega-3 PUFA supplementation was not associated with a lower risk of all-cause mortality, cardiac death, sudden death, myocardial infarction, or stroke based on relative and absolute measures of association.

Abstract
BACKGROUND Raised triglycerides (TG), decreased high-density lipoprotein cholesterol (HDL-C) levels and a predominance of small dense low density lipoproteins (sdLDL) are characteristics of the metabolic syndrome (MetS). OBJECTIVE To compare the effect of high-dose rosuvastatin monotherapy with moderate dosing combined with fenofibrate or ω-3 fatty acids on the lipoprotein subfraction profile in patients with mixed dyslipidaemia and MetS. METHODS We previously randomised patients with low-density lipoprotein cholesterol (LDL-C) > 160 and TG > 200 mg/dl to rosuvastatin monotherapy 40 mg/day (R group, n = 30) or rosuvastatin 10 mg/day combined with fenofibrate 200 mg/day (RF group, n = 30) or ω-3 fatty acids 2 g/day (Rω group, n = 30). In the present study, only patients with MetS were included (24, 23 and 24 in the R, RF and Rω groups respectively). At baseline and after 12 weeks of treatment, the lipoprotein subfraction profile was determined by polyacrylamide 3% gel electrophoresis. RESULTS The mean LDL size was significantly increased in all groups. This change was more prominent with RF than with other treatments in parallel with its greater hypotriglyceridemic capacity (p < 0.05 compared with R and Rω). A decrease in insulin resistance by RF was also noted. Only RF significantly raised HDL-C levels (by 7.7%, p < 0.05) by increasing the cholesterol of small HDL particles. The cholesterol of larger HDL subclasses was significantly increased by R and Rω. CONCLUSIONS All regimens increased mean LDL size; RF was the most effective. A differential effect of treatments was noted on the HDL subfraction profile.

Abstract
BACKGROUND Metabolic syndrome [MetS] is a chronic, progressive and multi-complex health problem that can trigger physical, emotional and psychosocial problems. The aim of this study is to investigate the association between MetS and health-related quality of life (HRQoL) as well as depressive and anxiety disorders. METHODS New consecutive patients who attended an outpatient lipid clinic for evaluation for MetS were eligible for inclusion in the study. The MetS was defined according to the new definition of International Diabetes Federation (IDF). The medical outcomes study, short form-36 (SF-36) was used to assess HRQoL. Anxiety and depressive symptoms were assessed by a validated Greek version of the hospital anxiety and depression scale (HADS). RESULTS Three hundred and fifty-nine subjects were involved of whom 206 [57.4%] met the diagnostic criteria for the MetS (cases) and 153 [42.6%] were free of MetS criteria (comparator group). MetS was associated with lower scores of all subscales of the SF-36 except of bodily pain. The physical component summary score of SF-36 was independently associated with gender (β = 2.41, P = .01), married or living together (β = 5.18, P = .001) and satisfactory household income (β = 5.77, P < .0001). The mental component summary score of SF-36 was independently associated with gender (β = 3.20, P = .003) and satisfactory household income (β = 3.94, P = .02). A predominance of anxiety and depressive symptoms was observed among subjects with MetS. CONCLUSIONS Our study demonstrated that subjects with MetS have significantly more impaired HRQoL than those without MetS. These findings suggest that HRQoL should be considered in the management of subjects with MetS.

Abstract
BACKGROUND Statin treatment may be associated with adverse effects on glucose metabolism. Whether this is a class effect is not known. In contrast, ezetimibe monotherapy may beneficially affect insulin sensitivity. OBJECTIVE The aim of this study was to compare the effects of three different regimens of equivalent low-density lipoprotein cholesterol (LDL-C) lowering capacity on glucose metabolism. METHODS A total of 153 patients (56 men), who had not achieved the LDL-C goal recommended by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) despite a 3-month dietary and lifestyle intervention, were randomly allocated to receive open-label simvastatin 40 mg or rosuvastatin 10 mg or simvastatin/ezetimibe 10/10 mg for 12 weeks. The primary end point was changes in homeostasis model assessment of insulin resistance (HOMA-IR). Secondary endpoints consisted of changes in fasting insulin levels, fasting plasma glucose (FPG), glycosylated haemoglobin (HbA(1c) ), the HOMA of β-cell function (HOMA-B) (a marker of basal insulin secretion by pancreatic β-cells), LDL-C and high sensitivity C reactive protein (hsCRP). RESULTS At week 12, all three treatment regimens were associated with significant increases in HOMA-IR and fasting insulin levels (p < 0.05 compared with baseline). No significant difference was observed between groups. No change in FPG, HbA(1c) and HOMA-B levels compared with baseline were noted in any of the three treatment groups. Changes in serum lipids and hsCRP were similar across groups. CONCLUSION To the extent that simvastatin 40 mg, rosuvastatin 10 mg and simvastatin/ezetimibe 10/10 mg are associated with adverse effects on insulin resistance, they appear to be of the same magnitude.

Clopidogrel vs. aspirin treatment on admission improves 5-year survival after a first-ever acute ischemic stroke. data from the Athens Stroke Outcome Project. Arch Med Res 2011; 42:443-50.

Abstract
BACKGROUND AND AIMS We undertook this study to compare the impact of aspirin vs. clopidogrel treatment on 5-year survival of patients experiencing a first-ever acute ischemic noncardioembolic stroke. METHODS This was a retrospective study involving patients with an acute ischemic stroke who had an indication for antiplatelet therapy (atherothrombotic, lacunar and cryptogenic stroke subtype). A total of 1228 (383 women) hospitalized due to an acute first-ever stroke and receiving aspirin (n = 880) or clopidogrel (n = 348) were finally involved. To determine the factors that independently predict 5-year survival statistical analysis including the Kaplan-Meier survival curve and multifactorial analysis (Cox regression) was performed. RESULTS Subjects treated with clopidogrel had improved 5-year survival compared with those receiving aspirin (log rank test: 16.4, p <0.0001). The difference in survival was evident as early as 6 months from index stroke: cumulative survival 93.8% for aspirin vs. 97% for clopidogrel (log rank test: 4.01, p = 0.045). The composite cardiovascular event (including stroke recurrence, myocardial infarction, unstable angina, coronary revascularization, aortic aneurysm rupture, peripheral atherosclerotic artery diseases, and sudden death) rates were lower in the clopidogrel group (n = 60, 17.2%) compared with the aspirin (n = 249, 28.3%) group (log rank test: 12.4, p <0.0001). This preferential effect of clopidogrel over aspirin was independent of age, gender, presence of cardiovascular disease other than stroke or cardiovascular risk factors as well as irrespective of the severity of stroke and days of hospitalization. CONCLUSIONS This study supports that clopidogrel is superior to aspirin in preventing death and cardiovascular events after an acute noncardioembolic ischemic stroke.

JUPITER and satellites: Clinical implications of the JUPITER study and its secondary analyses. World J Cardiol 2011; 3:207-14. [PMID: 21860701 PMCID: PMC3158868 DOI: 10.4330/wjc.v3.i7.207] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2011] [Revised: 05/21/2011] [Accepted: 05/28/2011] [Indexed: 02/06/2023] Open
Abstract
THE JUSTIFICATION FOR THE USE OF STATINS IN PREVENTION: an intervention trial evaluating rosuvastatin (JUPITER) study was a real breakthrough in primary cardiovascular disease prevention with statins, since it was conducted in apparently healthy individuals with normal levels of low-density lipoprotein cholesterol (LDL-C < 130 mg/dL) and increased inflammatory state, reflected by a high concentration of high-sensitivity C-reactive protein (hs-CRP ≥ 2 mg/L). These individuals would not have qualified for statin treatment according to current treatment guidelines. In JUPITER, rosuvastatin was associated with significant reductions in cardiovascular outcomes as well as in overall mortality compared with placebo. In this paper the most important secondary analyses of the JUPITER trial are discussed, by focusing on their novel findings regarding the role of statins in primary prevention. Also, the characteristics of otherwise healthy normocholesterolemic subjects who are anticipated to benefit more from statin treatment in the clinical setting are discussed. Subjects at "intermediate" or "high" 10-year risk according to the Framingham score, those who exhibit low post-treatment levels of both LDL-C (< 70 mg/dL) and hs-CRP (< 1 mg/L), who are 70 years of age or older, as well as those with moderate chronic kidney disease (estimated glomerular filtration rate < 60 mL/min every 1.73 m(2)) are anticipated to benefit more from statin treatment. Unlikely other statin primary prevention trials, JUPITER added to our knowledge that statins may be effective drugs in the primary prevention of cardiovascular disease in normocholesterolemic individuals at moderate-to-high risk. Also, statin treatment may reduce the risk of venous thromboembolism and preserve renal function. An increase in physician-reported diabetes represents a major safety concern associated with the use of the most potent statins.
