Aims: Migration of monocytes into the arterial wall contributes to arterial inflammation and atherosclerosis progression. Since elevated low-density lipoprotein cholesterol (LDL-C) levels have been associated with activation of plasma monocytes, intensive LDL-C lowering may reverse these pro-inflammatory changes. Using proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies (mAbs) which selectively reduce LDL-C, we studied the impact of LDL-C lowering on monocyte phenotype and function in patients with familial hypercholesterolaemia (FH) not using statins due to statin-associated muscle symptoms...

INTRODUCTION: The first symptoms of myasthenia gravis (MG) usually involve weakness of the ocular muscles, making it relevant that ophthalmologists have updated information on studies as regards its relationship with the consumption of drugs, such as statins. MATERIALS AND METHODS: A bibliometric analysis was performed using the Scopus database and by a search strategy in the selection of documents containing descriptors related to statins in the «Title» («TI») field and the descriptors «ophthalm *', «myast *', «visual *' in other fields of the document (period 1986-2015)...

BACKGROUND AND AIM: The increasing number of coronary artery bypass grafting (CABG) is associated with a need for active introduction of methods improving immediate and long-term results of these interventions. Results of a number of studies conducted during recent years allow to consider high dose statin therapy one of such methods. In this article we present results of rosuvastatin administration to patients with ischemic heart disease (IHD) prior to surgery. METHODS: Rosuvastatin (40 mg/day) was given for 4 weeks before CABG to patients who had previously taken simvastatin (20 mg/day)...

Importance: In the Improved Reduction of Outcomes: Vytorin Efficacy International Trial, intensive low-density lipoprotein cholesterol (LDL-C)-reducing therapy with ezetimibe/simvastatin compared with simvastatin alone was associated with a significant reduction in cardiovascular events in 18 144 patients after acute coronary syndrome. The safety of very low LDL-C levels over the long-term is unknown. Objective: To assess the safety and clinical efficacy of achieving a very low (<30 mg/dL) level of LDL-C at 1 month using data from the Improved Reduction of Outcomes: Vytorin Efficacy International Trial...

OBJECTIVES: Prompted by the few studies available in the literature, we analysed patients with necrotising myopathy associated with anti-signal recognition particle (anti-SRP). METHODS: We conducted a retrospective, single-centre cohort study involving 14 patients with anti-SRP antibody followed between 2001 and 2016. RESULTS: Patients had a mean age at disease onset of 40.7 years and were predominantly female and of white ethnicity. At disease onset, all patients had limb muscle weakness with median serum of creatine phosphokinase level of 8080U/L, 64...

BACKGROUND: Statins are a group of drugs that reduce the levels of triglycerides and cholesterol in blood by inhibiting HMG-CoA reductase, an enzyme involved in rate limiting step in cholesterol synthesis. About 2-20% patients on statins develop toxic myopathies, which usually resolve on discontinuation of statin. More recently, an immune-mediated necrotizing myopathy has been found to be associated with statin use which in most cases requires treatment with immunosuppressants. OBJECTIVE: To perform a systematic review on published case reports and case series of statin-associated autoimmune myopathy...

BACKGROUND: Statins have well-known benefits in the prevention of cardiovascular disease, however, 7-29% of patients develop muscle side effects and up to 0.5% develop severe symptoms. Mitochondrial dysfunction has been associated with severe statin-induced myopathy (SM); however, there is a paucity of systematic studies in affected individuals. OBJECTIVES: The goal of this study was to combine clinical and laboratory features with quantitative biochemical and histopathologic studies of skeletal muscle biopsies from SM cases to determine what proportion could be attributed to mitochondrial dysfunction and how many of these had primary respiratory chain defects...

Delayed recovery from anesthesia remains a very challenging subject for anesthesiologists. This case report describes the clinical course of delayed recovery from neuromuscular blockade after laparoscopic partial nephrectomy in a patient on simvastatin. The patient was hypertensive on regular treatment with oral captopril 25 mg twice daily and amlodipine 5 mg once daily and hypercholesterolemic on regular simvastatin 40 mg once daily with a normal electrocardiogram (ECG). All preoperative laboratory findings were within normal ranges...

Skeletal muscle (SKM) injury is one of the major safety concerns in risk assessment for drug development. However, no appropriate pre-clinical animal model exists to evaluate drug-induced SKM injury except that caused by fibrates and statins. Thiazolidinedione, a PPARγ agonistic drug for type 2 diabetes mellitus, is widely used clinically but can induce adverse effects such as hepatotoxicity and SKM injury, as has been reported in recent decades. Moreover, thiazolidinedione-induced SKM injury has only been reported in humans, and no evidence of SKM injury has been observed in rodents...

BACKGROUND: Statins are used to lower cholesterol in plasma and are one of the most used drugs in the world. Many statin users experience muscle pain, but the mechanisms are unknown at the moment. Many studies have hypothesized that mitochondrial function could be involved in these side effects. AIM: The aim of the study was to investigate mitochondrial function after 2 weeks of treatment with simvastatin (S; n = 10) or pravastatin (P; n = 10) in healthy middle-aged participants...

The efficacy of statins is related to the 'common soil' hypothesis, which proposes oxidative stress and inflammation as main pathophysiologic processes in the disease group of diabetes and endothelial dysfunction. This study evaluated the recovery of erectile function after administration of chronic statin alone in streptozotocin (STZ)-induced diabetes mellitus (DM) rats, focusing on the anti-oxidative effects and consequentially recuperated endothelial function. A total of 45 male Sprague-Dawley rats (8 weeks old) were divided into three groups (n = 15 each): an age-matched normal control group (Control group), an uncontrolled DM group (DM group), and a statin-treated group (Statin group)...

Administration of simvastatin was followed by a decrease in activities of superoxide dismutase and cytochrome oxidase in rat mitochondria, which attested to dysfunction of the respiratory chain. The decrease in total ATPase and Ca(2+)-ATPase activities in muscle tissue homogenates reflected impaired transport of active cations essential for muscle contraction. We conclude that abnormal relationships in the system of energy synthetic and energy-dependent processes in myocytes serve as the molecular basis for the formation of statin-induced degenerative changes...

Simvastatin induced rhabdomyolysis with renal failure is a well reported clinical entity with hyperkalemia recognized as a life threatening risk. The risk of delayed hypercalcemia during the recovery of renal function is not well appreciated as this varies in severity and can be caused by multiple mechanisms. We present a patient with high dose simvastatin induced rhabdomyolysis leading to late onset of severe hypercalcemia due to calcium phosphate deposition in muscles diagnosed by distinctive bone scintigraphy...

A 49-year-old woman presented with progressive muscle weakness of the limbs and dysphagia. Her past and family medical history were unremarkable and she did not take statins or any other medications. Laboratory tests showed that serum levels of creatine kinase were elevated (13,565 IU/l) and anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) antibodies were detected in the serum. Other autoantibodies to the nuclear (ANA), RNP, aminoacyl-tRNA synthetases (ARS), and signal recognition particle (SRP) were negative...

REVIEW
Patrick du Souich, Ghislaine Roederer, Robert Dufour
Statins are effective drugs to reduce cardiovascular events secondary to dyslipidemia; however, they cause frequent undesirable side effects. The incidence of statin-induced myotoxicity (SIM) is presented by 7 to 29% of patients, depending upon the report. SIM may develop in presence of abnormally high concentrations of statins in the myocyte and/or in presence of muscular conditions that may predispose to SIM. High concentrations of statins in the myocyte may occur whenever the activity of liver influx membrane transporters, namely OATP1B1, of drug metabolizing enzymes, and of liver and muscular efflux transporters, MDR1 and BCRP, is reduced...

Physicians are among those prescribed statins and therefore, subject to potential statin adverse effects (AEs). There is little information on the impact of statin AEs on physicians affected by them. We sought to assess the character and impact of statin AEs occurring in physicians and retired physicians, and to ascertain whether/how personal experience of AEs moderated physicians' attitude toward statin use. Seven active or retired physicians from the United States communicated with the Statin Effects Study group regarding their personal experience of statin AEs...

We tested the hypothesis that a 6-week regimen of simvastatin would attenuate skeletal muscle adaptation to low-intensity exercise. Male C57BL/6J wildtype mice were subjected to 6-weeks of voluntary wheel running or normal cage activities with or without simvastatin treatment (20 mg/kg/d, n = 7-8 per group). Adaptations in in vivo fatigue resistance were determined by a treadmill running test, and by ankle plantarflexor contractile assessment. The tibialis anterior, gastrocnemius, and plantaris muscles were evaluated for exercised-induced mitochondrial adaptations (i...

PURPOSE OF REVIEW: In the last 6 years, our understanding of statin-associated myopathy expanded to include not only a toxic myopathy with limited and reversible side-effects but also an autoimmune variety in which statins likely induce an autoimmune myopathy that is both associated with a specific autoantibody and responsive to immunosuppression and immune modulation. This review widens the reader's understanding of statin myopathy to include an autoimmune process. RECENT FINDINGS: Statin-associated immune-mediated myopathy provides an example of an environmental trigger (statins) directly implicated in an autoimmune disease associated with a genetic predisposition as well as potential risk factors including concomitant diseases and specific statins...

Statins may offer protective effects in sepsis through anti-inflammatory, mitochondrial protection and other actions. We thus evaluated the effects of simvastatin on survival, organ and mitochondrial function, tissue and plasma ubiquinone levels and liver transcriptomics in a 3-day rat model of sepsis. Comparisons of rat plasma simvastatin and ubiquinone levels were made against levels sampled in blood from patients with acute lung injury (ALI) enrolled into a trial of statin therapy. Animals received simvastatin by gavage either pre- or post-induction of faecal peritonitis...

BACKGROUND: Non-muscle-invasive bladder cancer (NMIBC) is especially prevalent among the elderly. Many patients with NMIBC also have significant concomitant comorbidities, including cardiovascular diseases and hypercholesterolemia. Statins are the most commonly used cholesterol-depleting agents, and they may possess anticancer properties. The objective of this population-based study was to evaluate the effect of statins on the survival of individuals diagnosed with NMIBC. METHODS: This is a retrospective population-based cohort study that used administrative databases to identify individuals 66 years of age and older who were diagnosed with NMIBC between 1992 and 2012...
