One-year atorvastatin treatment in hypercholesterolemic patients with or without carotid artery disease.
2006
Aim. Statins are the drugs of choice in heterozygous familial hypercholesterolemia (FH), which has a high risk of premature cardiovascular events including myocardial infarction, stroke, and surgical revascularization. Methods. A 1-year open-label study was conducted to test the efficacy and tolerability of Atorvastatin titrated to the target, in proven FH patients and to evaluate certain inflammatory parameters. One hundred and two FH patients (44 men and 58 women; mean age 58.7±3.6 years) were included in the study. After evaluation using the B-mode duplex scanning system of extracranial carotid arteries, the patients were divided into groups: Group 1 (15 men, 25 women) with carotid plaqu…
Statin intolerance – an attempt at a unified definition. Position paper from an International Lipid Expert Panel
2015
Statins are one of the most commonly prescribed drugs in clinical practice. They are usually well tolerated and effectively prevent cardiovascular events. Most adverse effects associated with statin therapy are muscle-related. The recent statement of the European Atherosclerosis Society (EAS) has focused on statin-associated muscle symptoms (SAMS), and avoided the use of the term 'statin intolerance'. Although muscle syndromes are the most common adverse effects observed after statin therapy, excluding other side effects might underestimate the number of patients with statin intolerance, which might be observed in 10 - 15% of patients. In clinical practice, statin intolerance limits effecti…
Lipid-lowering therapy use in primary and secondary care in Central and Eastern Europe: DA VINCI observational study.
2021
Abstract Background and aims Central and Eastern Europe (CEE) is a largely understudied region, despite having the highest cardiovascular disease mortality in Europe. This analysis aimed to assess the proportion of patients in CEE who achieved their LDL-C goals based on individual cardiovascular risk recommended by the 2016 and 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines. Methods The DA VINCI study was a cross-sectional observational study of primary and secondary prevention patients receiving lipid-lowering therapy across Europe between June 2017 and November 2018. Results In total, 2154 patients were enrolled from the Czech Republic (n = 509…
Statin use improves the efficacy of nivolumab in patients with advanced renal cell carcinoma
2022
Background: Statins are widely used in an ageing population, including subjects with solid malignancies. However, no conclusive evidence is currently available on their potential influence on patients' outcome. We aimed to assess whether statin exposure affects the survival of patients with metastatic renal cell carcinoma (mRCC) treated with nivolumab.Patients and methods: Medical records of patients with documented mRCC treated with second- or third-line nivolumab were reviewed at ten institutions from Italy, Spain and the USA. Patients were assessed for overall survival (OS), progression-free survival (PFS), and overall clinical benefit. Univariate and multivariate analyses were used to e…
Carotid Atherosclerosis Evolution When Targeting a Low-Density Lipoprotein Cholesterol Concentration70 mg/dL After an Ischemic Stroke of Atherosclero…
2020
Background: The TST trial (Treat Stroke to Target) showed the benefit of targeting a low-density lipoprotein cholesterol (LDL-C) concentration of <70 mg/dL in terms of reducing the risk of major cardiovascular events in 2860 patients with ischemic stroke with atherosclerotic stenosis of cerebral vasculature. The impact on carotid atherosclerosis evolution is not known. Methods: TST-PLUS (Treat Stroke to Target–Plaque Ultrasound Study) included 201 patients assigned to an LDL-C concentration of <70 mg/dL and 212 patients assigned to a target of 100±10 mg/dL. To achieve these goals, investigators used the statin and dosage of their choice and added ezetimibe as needed. Ultrasonographer…
Lovastatin causes sensitization of HeLa cells to ionizing radiation‐induced apoptosis by the abrogation of G2 blockage
2003
To investigate the effect of inhibition of Ras/Rho-regulated signalling by 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) on radiation-induced cell killing and apoptosis.Different human cell lines were pretreated or not with lovastatin before exposure to gamma-rays. Afterwards, radiation-induced cell killing, formation and repair of double-strand breaks, activation of radiation-inducible signal mechanisms (i.e. p53, p21, extracellular-signal-related kinase (ERK), NF-kappaB), changes in cell cycle progression and apoptosis were analysed.As shown by a colony formation assay, lovastatin sensitized HeLa cells to gamma-radiation-induced cell killing. The lovastati…
Potential use of HMG-CoA reductase inhibitors (statins) as radioprotective agents
2011
HMG-CoA reductase inhibitors (statins) are widely used in the therapy of hypercholesterolemia. Apart from their lipid-lowering activity, they have pleiotropic effects that are attributed to the inhibition of regulatory proteins, including Ras-homologous (Rho) GTPases. Here, we discuss the potential usefulness of statins to prevent normal tissue damage provoked by radiotherapy. Statins reduce the mRNA expression of pro-inflammatory and pro-fibrotic cytokines stimulated by ionizing radiation in vitro and alleviate IR-induced inflammation and fibrosis in vivo. The currently available data indicate that statins accelerate the rapid repair of DNA double-strand breaks and, moreover, mitigate the …
Lovastatin protects human endothelial cells from the genotoxic and cytotoxic effects of the anticancer drugs doxorubicin and etoposide
2006
Background and purpose: 3-Hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) are frequently used lipid-lowering drugs. Moreover, they exert pleiotropic effects on cellular stress responses and death. Here, we analysed whether lovastatin affects the sensitivity of primary human endothelial cells (HUVEC) to the anticancer drug doxorubicin. Experimental approach: We investigated whether pretreatment of HUVEC with low dose of lovastatin influences the cellular sensitivity to doxorubicin. To this end, cell viability, proliferation and apoptosis as well as DNA damage-triggered stress response were analysed. Key results: Lovastatin reduced the cytotoxic potency of doxorub…
Ultraviolet light-induced apoptotic death is impaired by the HMG-CoA reductase inhibitor lovastatin.
2003
HMG-CoA reductase inhibitors (i.e., statins) attenuate C-terminal isoprenylation of Rho GTPases, thereby inhibiting UV-C-induced activation of c-Jun-N-terminal kinases/stress-activated protein kinases (JNKs/SAPKs). Inhibition of UV-C-triggered JNK/SAPK activation by lovastatin is due to inhibition of Rac-SEK1/MKK4-mediated phosphorylation of JNKs/SAPKs at Thr183/Tyr185. UV-C-stimulated phosphorylation of p38 kinase (Thr180/Tyr182) is also impaired by lovastatin. Cell killing provoked by UV-C irradiation was significantly inhibited by lovastatin. This was paralleled by a reduced frequency of chromosomal aberrations, accelerated recovery from UV-C-induced transient replication blockage, inhib…
Lipid-lowering drug use in Italian primary care: effects of reimbursement criteria revision
2008
OBJECTIVE: To assess whether the prescribing pattern of lipid-lowering drugs (LLD) changed after reimbursement criteria revision in a general practice in southern Italy. METHODS: From the Caserta-1 Local Health Service database, 93 general practitioners (GPs) who had consistently sent data about their patients during the years 2003-2005 were recruited. Prevalence of use and incidence of new treatments were calculated for each year, stratified by three drug cohorts: statins, omega-3 fatty acids, and fibrates. Subanalyses by gender, age, and indication of use were performed. RESULTS: Overall, 1-year prevalence of LLD use increased from 2003 to 2004. After reimbursement criteria revision (Nove…
