OBJECTIVE: Atorvastatin reduces the incidence of cardiovascular events. However, the effects of atorvastatin on platelet aggregation are unknown. METHODS: Blood samples were obtained from 126 healthy volunteers. Prepared isolated platelet suspensions were adjusted with saline to three different concentrations of 100 × 10(9), 300 × 10(9), and 600 × 10(9) platelets/L. Platelet samples were incubated with atorvastatin (10(-7 )mol/L, 10(-6 )mol/L or 10(-5 )mol/L), and stimulated with ADP (10 µmol/L), arachidonic acid (0...

Statins, 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitors have been shown to improve diabetic nephropathy. However, whether they provide protection via Histone deacetylases (HDAC) inhibition is not clear. We conducted a comparative evaluation of Atorvastatin (AT) versus the non-statin cholesterol-lowering drug, Ezetimibe (EZT) on severity of diabetic nephropathy. Streptozotocin-treated male Wistar rats were fed a cholesterol-supplemented diet and gavaged daily with vehicle, AT or EZT. Control rats received normal diet and gavaged vehicle (n = 8-9/group)...

MicroRNA-122 (miR-122) is abundant in the liver and involved in lipid homeostasis, but its relevance to the long-term risk of developing metabolic disorders is unknown. We therefore measured circulating miR-122 in the prospective population-based Bruneck Study (n=810; survey year: 1995). Circulating miR-122 was associated with prevalent insulin resistance, obesity, metabolic syndrome, type-2 diabetes, and an adverse lipid profile. Among 92 plasma proteins and 135 lipid subspecies quantified with mass spectrometry, it correlated inversely with zinc-alpha-2-glycoprotein and positively with afamin, complement-factor H, VLDL-associated apolipoproteins, and lipid subspecies containing monounsaturated and saturated fatty acids...

This study seeks to investigate potential cardioprotection of Danlou Tablets in patients undergoing PCI with non-ST elevation acute coronary syndrome (NSTE-ACS). 219 patients with NSTE-ACS were randomised to Danlou Tablet pretreatment (n = 109) or placebo (n = 110). No patients received statins prior to PCI and all patients were given atorvastatin (10 mg/day) after procedure. The main endpoint was the composite incidence of major adverse cardiac events (MACEs) within 30 days after PCI. The proportion of patients with elevated levels of cTn I>5 × 99% of upper reference limit was significantly lower in the Danlou Tablet group at 8 h (22...

: Preliminary evidence suggests that statins may prevent major perioperative vascular complications. METHODS: We randomized 648 statin-naïve patients who were scheduled for noncardiac surgery and were at risk for a major vascular complication. Patients were randomized to a loading dose of atorvastatin or placebo (80 mg anytime within 18hours before surgery), followed by a maintenance dose of 40 mg (or placebo), started at least 12hours after the surgery, and then 40 mg/d (or placebo) for 7days...

A 70-year-old man with hypertension was admitted to our coronary ICU with acute anterior MI. Emergent primary PCI was planned and coronary angiography was performed. LAD artery was totally occluded in the proximal segment just after a huge 32 × 26 mm sized aneurysm. Emergent CABG operation was performed in 75 minutes because of multivessel disease including the RCA and left circumflex artery. Aneurysm was ligated and coronary bypass was performed using LIMA and saphenous grafts. The postoperative course of the patient was uneventful...

Large randomized controlled trials have not confirmed the effects of statin therapy on reduction of cardiovascular morbidity and mortality in end-stage kidney disease, despite that statins are still widely prescribed by nephrologists to chronic dialysis patients. The aim of the study was to analyze the attitudes of nephrologists towards statin use in hemodialysis patients. Self-designed questionnaire, containing 18 questions, was distributed among 115 nephrologists. The survey contained description of the results of 3 largest statin trials in nephrology...

The current study designed to clarify the mechanism of paraquat-induced cytotoxicity and protective effects of Atorvastatin on freshly isolated alveolar macrophages (AMs). AMs were collected via bronchoalveolar lavage and exposed to various concentrations of paraquat in the presence and absence of atorvastatin for 24h. Cell viability, myeloperoxidase activity; nitric oxide generation and total antioxidant capacity were assessed. Expression of TLR-4 at mRNA and protein levels were studied by using PCR and western blot methods Atorvastatin enhanced the paraquat-reduced cell viability and reduced the paraquat-induced myeloperoxidase activity and nitric oxide production...

Cardiovascular disease and depression often occur simultaneously in the same patient. Long-term polypharmacotherapy can lead to drug-induced oxidative stress. Data concerning the effects of concomitant treatment with atorvastatin and selective serotonin reuptake inhibitors (SSRIs) are lacking. The aim of the present study was to examine oxidative stress parameters in the blood of rats after 28 days treatment with atorvastatin combined with fluoxetine or paroxetine. The study was carried out on male Wistar rats weighing 200-250 g...

Chronic subdural haematoma (CSDH) is a common neurosurgical condition. Burr-hole for drainage is an effective treatment. However, recurrence can be up to 8-33% and is associated with morbidities and mortalities. The underlying pathogenesis was postulated to be localised inflammation and pathological aberrant vessels formation. Atorvastatin, an HMG-CoA reductase inhibitor, is a type of lipid-lowering medication. In animal studies and a preliminary clinical trial, Atorvastatin was shown to be effective in the treatment of CSDH...

PURPOSE: Therapeutic strategies that modulate ventricular remodeling can be useful after acute myocardial infarction (MI). In particular, statins may exert effects on molecular pathways involved in collagen metabolism. The aim of this study was to determine whether treatment with atorvastatin for 4 weeks would lead to changes in collagen metabolism and ventricular remodeling in a rat model of MI. METHODS: Male Wistar rats were used in this study. MI was induced in rats by ligation of the left anterior descending coronary artery (LAD)...

Recently, the European Society of Cardiology (ESC) and the European Atherosclerosis Society (EAS) published a consensus paper giving guidance on the definition and management of statin-associated muscle symptoms (SAMS), as well as the use of proprotein convertase subtilisin kexin 9 (PCSK9) inhibitors in very high-risk patients. The occurrence of SAMS can have a major negative impact on treatment adherence and, consequently, on the prognosis of cardiovascular diseases. In addition, both the ESC guidelines on the prevention of cardiovascular disease (CVD) in clinical practice with sections addressing global strategies to minimise the burden of CVD at population and individual levels, and the 2016 ESC/EAS guideline for the management of dyslipidaemias, focus on evaluation and treatment of SAMS...

BACKGROUND: Laboratory studies have demonstrated statin-induced apoptosis of cancer cells, including breast cancer cells, and evidence is accumulating on the mechanism of statin-induced apoptosis. However, despite numerous epidemiological studies, no consensus has been reached regarding the relationship between statin use and breast cancer risk. METHODS: This retrospective case-control study enrolled 4332 breast cancer patients and 21,660 age-matched controls registered in the National Health Insurance program of Taiwan, which covers approximately 99% of the population...

Doravirine is a novel, highly potent, once-daily non-nucleoside reverse transcriptase inhibitor in development for HIV-1 infection treatment. In vitro and clinical data suggest doravirine is unlikely to cause significant drug-drug interactions via major drug metabolizing enzymes or transporters. As a common HIV-1 infection comorbidity, hypercholesterolemia is often treated with statins, including the commonly prescribed atorvastatin. Atorvastatin is subject to drug-drug interactions with CYP3A4 inhibitors. Increased exposure due to CYP3A4 inhibition may lead to serious adverse events (AEs), including rhabdomyolysis...

BACKGROUND: 3-hydroxy-3-methylglutaryl coenzyme A reductase reductase inhibitors (statins) are generally well tolerated, with statin-associated muscle symptoms (SAMS) the most common side effect (~10%) seen in statin users. However, studies and clinical observations indicate that many of the self-reported SAMS appear to be nonspecific (ie, potentially not attributable to statins). OBJECTIVE: Mental health and well-being influence self-perception of pain, so we sought to assess the effect of baseline well-being and depression on the development of muscle pain with 6 months of atorvastatin 80 mg/d (ATORVA) or placebo in healthy, statin-naive adults...

Statins; a class of routinely prescribed cholesterol-lowering drugs; inhibit 3-hydroxy-3-methylglutaryl-coenzymeA reductase (HMGCR) and strongly induce endothelial thrombomodulin (TM); which is known to have anti-inflammatory; anti-coagulation; anti-oxidant; and radioprotective properties. However; high-dose toxicity limits the clinical use of statins. The vitamin E family member gamma-tocotrienol (GT3) also suppresses HMGCR activity and induces TM expression without causing significant adverse side effects; even at high concentrations...

In addition to its antioxidant properties, γ-tocotrienol also has the ability to inhibit HMG-CoA reductase, which is the key enzyme in the mevalonate pathway for cholesterol biosynthesis. Statins, the competitive inhibitors of HMG-CoA reductase, display potent anticancer activity and reversal ability of multidrug resistance in a variety of tumor cells, which is believed to be due to their inhibition of HMG-CoA reductase. Here, we determined the role of the mevalonate pathway in γ-tocotrienol-mediated reversal of multidrug resistance in cancer cells...

Although concern regarding the increased risk for new-onset diabetes mellitus (NODM) after statin treatment has been raised, there has been a lack of evidence in real-world clinical practice, particularly in East Asians. We investigated whether statin use is associated with risk for NODM in Koreans. We conducted a retrospective cohort study using the clinical research database from electronic health records. The study cohort consisted of 8265 statin-exposed and 33,060 matched nonexposed patients between January 1996 and August 2013...

REVIEW
Einar S Björnsson
Statins are generally well tolerated and adverse effects are relatively rare. Clinical trials are underpowered to detect uncommon adverse effects such as idiosyncratic drug-induced liver injury. This review is aimed at covering the current knowledge on the hepatotoxicity associated with statins and other lipid lowering drugs. Both atorvastatin and simvastatin have been associated with more than 50 case reports of liver injury and other statins have been implicated in this type of liver injury as well. Idiosyncratic liver injury due to statins has been reported to occur 1...
